Trust and Safeguards in Information Security: An Organizational Perspective

The word "Trust" is defined as related to information security. Based on ones understanding of securing your environment, what are some of the common safeguards is recommend to ensure trust is viable in an organization?

Defining Trust in Information Security

Trust as defined by Jacobs (2016) is a characteristic allowing one entity to assume that a second entity will behave exactly as the first entity expects. Trust can be viewed as assurance in the honesty, skill, character, and certainty of a person or thing.

Personnel and Physical Security in Information Assurance

Personnel Security

Process and procedures are needed to protect personnel security as Jacobs (2015) points out. The employee responsibilities need to be defined, and the employee must qualify for the role so that the risk is reduced from theft, fraud, or misuse of assets by the employee. An excellent example of checking personnel security or identities occurs in businesses that do work on behalf of the government. Each employee, visitor, supplier and any others that interact with the organization require having their identities checked and verified. In some cases, foreign personnel are unable to participate in specific meetings or able to conduct business in various parts of the building due to the sensitive nature of the information handled and discussed. Security policies and procedures for the organization identify what personnel can and cannot do including terminations or disciplinary action was taken for any wrongdoing as discussed by Jacobs (2015). Regular training by the organization is required do be sure team members are up to date with regulations and required constraints that need to be followed. At the time of employment as Jacobs (2015) a job description, already in place is provided to the employee, and the terms and conditions of the employment should be provided as defined by the human resources, compliance and legal teams. The job description should include any security roles and responsibilities required by the job candidate. A candidate background check and drug test also should be conducted before taking on a candidate for employment which will identify any past existing issues with the candidate. If the candidate is hired, the employment contract and nondisclosure agreement should be completed before any organizational assets are provided to the new employee.

Systems Engineering and Information Security Integration in the Development Lifecycle

Topic: Systems Engineering and Information Security

Systems Engineering Overview

Systems engineering centers on defining the client's requirements and functionality early in the development cycle. Then one refines and documents the requirements that represent the needs. The method continues into design synthesis, development, system validation, deployment, operation, and retirement while considering the entire problem or also known as the system life cycle (Jacobs, 2016, p. 31). In short systems engineering is an interdisciplinary method to building complex and technologically diverse systems as described by Douglass (2016).

Systems Engineering SIMILAR Methodology Example

Introduction

Systems engineering is an interdisciplinary team method meant to create a successful system as described by INCOSE. The systems engineering process takes into account both the business and technical needs of all the clients or customers. The ultimate goal of Systems Engineering is to provide a quality product that meets the client or customers needs as INCOSE points out. Systems engineering is concerned with handling a problem that is complex. The systems engineering process assists a team working on a solution to avoid omissions and invalid assumptions, can assist them in managing changing issues, and efficiently produce a cost-effective and robust solution as described by INCOSE. Using a systems engineering approach to building products and solutions efficient use of project cost and timeframes are managed and controlled effectively. The systems engineering team is always aware of the project requirements, interfaces and issues along with what the consequences are of making a change to the systems engineering plan and how the change will impact the overall project. Research showed, according to INCOSE, that systems engineering can save from 10% to 20% of a project's budget. INCOSE also points out that half of all project failure is preventable by using systems engineering techniques. The purpose of this paper is to discuss a practical example of System Engineering.

Understanding the Various Branches of Information Security

Mon, 03 Nov 2025 00:00:00 +0000

Understanding the Various Branches of Information Security

Introduction

The purpose of information security is to protect a companies or organization's valuable assets as Peltier (2013) points out. Information security includes securing computer hardware and software and information or data. The information security team, using the appropriate applications assist in defending the mission of the company or organization by protecting the physical and financial resources, reputation, legal position, employees and assets. An organizations information security program is devised so that security enables the organization to move forward not slow productivity down. For information security to become highly productive in a company, the company must explore and assess the information security risks to business unit(s) operations. The business or organization must also identify what policies, standards, and controls are essential in implementing to reduce the security risks identified. Promoting awareness and understanding amongst the team members is also required. Once policies, standards, and controls are implemented information security must assess the compliance and control effectiveness of what is put and place and revise if needed as Peltier (2013) discusses. The security enabled in a business must be layered in design and the approach to security is sometimes referred to as multilayered defense or defense in depth as Solomon, Kim, & Carrell (2015) discuss. The purpose of the paper is explain why it is important to understand the various branches of security.[^6][^8]

Amazon Web Services Cloud Information Security Risks and Compliance

Abstract

This paper examines the critical security considerations and compliance requirements for organizations migrating to Amazon Web Services (AWS) cloud infrastructure, addressing the widespread concerns among IT professionals regarding cloud security risks. The research explores AWS's Shared Responsibility Model as the fundamental framework for delineating security obligations between AWS and its customers, where AWS manages the security "of" the cloud infrastructure while customers maintain responsibility for security "in" the cloud. Through analysis of AWS's global infrastructure security services, the paper identifies key customer responsibilities including operating system security, data encryption, network configuration, and identity access management, while AWS maintains the physical infrastructure, hypervisor, and managed services.

Common Issues with Security Policy Implementation

Wed, 29 Oct 2025 00:00:00 +0000

Common Issues with Security Policy Implementation

Original Query

Discuss common issues with implementation of security policies and Discuss include common issues and possible mitigations to ensure policy can be enforced.

Common Implementation Issues

Implementation issues happen with security policies. Some of the common implementation issues, as described by Johnson (2014) are organization structure, fitting policies to leaders and targeting early adopters. The implementation of the policy has to take into account the type of organization, how large or small the organization is and what kind of technology is in use. One leader may present a security policy in a team meeting or town hall while another leader may be more hierarchical in the approach by holding a series of group meetings.

Introduction to Incident Response and Management

Incident response (IR) and Incident Management (IM) are similar when a disaster of any type occurs as described by Peltier (2013). IR and IM concepts document and developed and get utilized no matter why type of disaster that happened. The disaster could occur by computer security breach, a physical security attack or a natural disaster such as an earthquake.

Business Continuity and Disaster Recovery Planning Models

Mon, 27 Oct 2025 00:00:00 +0000

Compare and Contrast Various Business Continuity & Disaster Recovery Planning Models

Introduction

Business continuity is essential as described by Hiles (2014). It is the ability of an organization to survive and thrive, survive and bounce back after a disaster or catastrophes. The general objective is to accomplish the mission for the organization no matter what disruptions happen along the way. Business continuity as described by Rima (2013) focuses on an organization's capacity to continue operations irrespective of the nature of interruption. The business continuity planning (BCP) which is a methodology that can be studied, and practitioners can be certified by Rima (2013) points out. The disaster recovery plan is considered a subset of BCP since it addresses stopping the effects of the disaster, catastrophe or event. After the consequences of the disaster or event have been resolved, business continuity activities typically begin. Business continuity as described by Hiles (2014) is the constant readiness of all necessary assets that support critical business functions. Business continuity management (BCM) offers the readiness of the process and resources following a disruption in the business to ensure the continued achievement of mission critical objectives.

Types of Security Architecture and Design Models Explained

Sat, 25 Oct 2025 00:00:00 +0000

Appraise the Various Types of Security Architecture & Design Models

Security Architecture Overview

Security architecture is the view of the overall system architecture from a security perspective. Security architecture provides insight into the security services, mechanisms, technologies, and features that can be used to satisfy system security requirements as described by Tipton & Krause (2003). The security architecture offers recommendations in the context of the overall system architecture, and security mechanisms should be placed. The security view of a system architecture emphases the system security services and mechanisms, implementation of security related functionality, and identifies interdependencies among security-related components, services, mechanisms, and technologies, and at the same time reconciling any conflict between them. The security architecture is one aspect of an enterprise or system architecture, and can also include network architecture or connectivity architecture.

Physical Security Failure Points and Mitigation Strategies

Fri, 24 Oct 2025 00:00:00 +0000

Common Points of Failure and Strategies to Mitigate Physical Security Deficiencies

Layered Defense Approach

The nature of physical security ought to be like concentric rings or layers of defense with requirements for access that gets more difficult the closer one get to the center of the rings as described by Peltier (2013). The reason for the rings of security is evident because the security team takes some precautions to protect the organization.

Physical Security Models: Features and Functionality Compared

Thu, 23 Oct 2025 00:00:00 +0000

Evaluating the Features and Functionality of Various Physical Security Models

Three Levels of Information Security

Logical security, physical security, and premise security are the three levels of information security as described by Vacca (2013). Logical security protects data stored on computers from software and network threats. The physical safety or infrastructure security protects the information systems that store the data. Physical security must also protect the people who operate and maintain systems and those who use the data. Premises security normally entails protecting facilities security. Premise security protects the people and property within the facility or building(s) that make up the organization.

Cryptology Methods in Organizations, CAC vs. User/Password

Fri, 26 Apr 2024 00:00:00 +0000

Cryptology Methods in Organizations, CAC vs. User/Password

This text explores the different cryptology methods used for authentication within organizations. It compares the Common Access Card (CAC), used by federal agencies, with traditional username and password systems.

CAC: The CAC offers two-factor authentication with a physical card and a PIN. PKI certificates on the card enable encryption and secure communication. This method is more secure than single-factor authentication. However, it has limitations such as the "bathroom effect" and the inability to access multiple systems simultaneously.

Access Control Methods: MAC, DAC, RBAC, and More

Thu, 25 Apr 2024 00:00:00 +0000

Access Control Methods: A Comprehensive Guide

Access control is a cornerstone of information security, protecting valuable data and assets by regulating who or what can access them. This includes both physical and digital spaces. Access control systems enforce these rules, supporting the fundamental principles of confidentiality, integrity, and availability.

There are various access control categories:

Administrative controls: Policies, procedures, security awareness training
Physical controls: Security cameras, guards, locked rooms.
Technical controls: Encryption, smart cards, access control lists (ACLs).

Key access control models include:

Wed, 24 Apr 2024 00:00:00 +0000

Building Effective Security Awareness in Your Organization

In today's rapidly evolving technological landscape, security awareness is paramount. While technology improves, so do the tactics of bad actors. A robust security awareness program is essential for any organization to ensure that users understand and fulfill their information security responsibilities. This begins with clear policies and procedures, but must extend to continuous education and engagement. Effective security awareness empowers employees to recognize threats, protects valuable information assets, and fosters a strong security culture within the organization.

Symmetric, Asymmetric, and Hash Functions in Cryptography

Tue, 23 Apr 2024 00:00:00 +0000

Understanding Cryptography: Symmetric, Asymmetric, and Hash Functions

Cryptography, the practice of secure communication, encompasses several distinct approaches. Symmetric algorithms rely on a single, shared secret key between parties for both encryption and decryption. Asymmetric (public key) algorithms use a pair of keys – one public for encryption, and one private for decryption. Hash functions produce unique "fingerprints" of data, ensuring integrity and enabling applications like password storage. Understanding these distinct algorithms is crucial for choosing the appropriate method to protect sensitive information in various digital contexts.

Why is an Information Security Program Important for Your Company?

Understand why information security programs are crucial for businesses. Learn how they protect assets, raise awareness, and manage risks.

Why is an information security program important?

Information security is relevant and essential to a company because it protects the organization's valuable resources. A few examples of organization assets to protect are computer hardware, applications code, legal documents, and physical security of the organization office, as Peltier (2013) discusses. The security team in the organization must pick and implement the appropriate safeguards that assist the company's mission by defending financial and physical resources, their reputation, the employees, and any other tangible or intangible assets. Some employees believe security, as Peltier (2013) points out, prevents organizational goals from being reached by putting poorly selected rules and procedures on members of the organization and systems in place. A set of well-written policies, standards, and procedures are put in place to protect assets and support all business objectives.

Internet of Things (IoT): Rise and Impact on Daily Life

Fri, 01 Mar 2024 00:00:00 +0000

Internet of Things (IoT) and its Impact on Our Lives

A technological trend that started in its infancy years ago is now proliferating: the use of the Internet of Things (IoT). The term IoT was coined in 1982, as described by research by Farooq, Waseem, Mazhar, Khairi, and Kamal (2015). They describe the first IoT project as a modified Coke machine, which was network-enabled and connected to the Internet. The Coke machine could remotely identify the number of cans in the machine and whether they were cold over the Internet. In 1991, Mark Weiser, a visionary who worked at Parc Xerox, had a contemporary vision of IoT, back then called ubiquitous computing. Weiser envisioned embedding microprocessors in everyday objects so they can communicate information. Kevin Ashton, in 1999, proposed the term “Internet of Things” to describe a system of interconnected devices. The basic idea of IoT is to allow the exchange of information between invisibly embedded different real-world devices around us.

Wired vs. Wireless Data Transmission: Impact and Differences

Thu, 29 Feb 2024 00:00:00 +0000

Gain an Understanding Data Transmission: Wired vs. Wireless and Their Impact

Transmissions are impacted by different problems depending on the method of data transmission. The two types of data communications or transmissions are guided and unguided transmission, as Comer (2014) discusses. Guided media or wire transmissions consist of fiber optic, coaxial cable, and copper or aluminum twisted pair wire, as Varrall (2011) discusses. Unguided media, also known as wireless communication, transports electromagnetic waves with no physical conductor. Instead of physical conductors, the signal is broadcast via air and, therefore, is made accessible to someone having a device capable of receiving them, as Shinde (2000) describes.

DSL, Cable, Fiber & Cellular: Broadband Technologies Guide

What is Broadband? Different Types of Broadband Technologies Explained

What Is Broadband?

Broadband has grown worldwide, promoted by policymakers, network operators, and content providers, but it does not have a single standardized definition worldwide, as described by Kelly (2012). Broadband can mean multiple aspects of the network and services. This may or may not include:

The infrastructure used to deliver broadband services.
High-speed access to the Internet.
Services and applications available via broadband networks.

As Kelly (2012) points out, many countries established broadband based on the speed of services and applications offered on the network. Due to each country’s unique needs and history, including economic, geographic, and regulatory factors, definitions of broadband vary widely.

Database Failure Types, Causes, and Recovery Solutions

Sat, 24 Feb 2024 00:00:00 +0000

Types of Computer Failures

Database failures can usually be categorized into transaction, system, or media failures. Failed transactions in the middle of the execution can occur for many reasons, as described by Elmasri & Navathe (2015).

Most Common Failures:

The most common failures are described as computer failure, transaction or system error, exception or local error, database concurrency, or deadlock.

Computer failure:

Computer failures, sometimes called system crashes by specialists, occur when a piece of hardware fails. In high-end systems, there are usually redundant hardware components to keep the failures from occurring, but they do happen. A software failure is another type of computer failure. The software failure could be due to a vendor defect or by an application programming defect introduced in the code. The last example of a computer failure would be a network failure. A network failure can occur when a firewall change is introduced, the Internet connection fails, the firmware is updated on the switch, or other networking issues.

Disaster Recovery from Catastrophic Database Failures

Fri, 23 Feb 2024 00:00:00 +0000

Describe how disaster recovery from catastrophic failures is handled. Illustrate in detail

Catastrophes can be broken down into two subcategories: physical problems and catastrophes. Physical catastrophes can be air conditioner failures, power issues, fire, or hacking attacks. Catastrophic errors are usually caused by major disasters such as earthquakes or floods, which deem the data center no longer usable, as Elmasri & Navathe (2015) described.

When a physical problem or failure occurs with the database, such as a power outage, the database has restart capabilities built into it at start-up. The server power is restored, and the database management system is started. When starting, the database will go into recovery mode and replay or REDO the transactions in flight when the power outage occurred.

Essential Measures for Preventing SQL Injection Attacks

Thu, 22 Feb 2024 00:00:00 +0000

Preventive Measures Against SQL Injection Attacks

An SQL injection attack occurs by having an attacker inject a string input into the application; these changes or manipulate the SQL statement to the attacker’s advantage, as described by Elmasri & Navathe (2015). They indicate that an SQL injection attack inflicts damage to the database management system. Examples of ways damage could be done are unauthorized manipulation of data, retrieval of sensitive data, or execution of operating system-level commands.

Functional Dependency Closure Explained for Database Design

Sat, 17 Feb 2024 00:00:00 +0000

What Is Meant by the Closure of a Set of Functional Dependencies?

A functional dependency is a one-way dependency between two attributes at any given time. For a unique attribute

of value A there is one value of the attribute B associated with it through the relation. Even if the values for the attribute change, there is only one, as described by Harrington(2009). A functional dependency, as explained by Elmasri & Navathe (2015), is a constraint between two sets of attributes from the database.

Variable-Length Records and Separator Characters Explained

Sat, 17 Feb 2024 00:00:00 +0000

The Reasons For Having Variable-Length Records And The Use Of Separator Characters

There may be many reasons for a file having variable-length records, as described by Elmasri & Navathe (2015). They are described as one field that may need to be a varying size, a field that may contain a repeating group or value, a field that may be identified as an optional field, or a file that may contain more than one record type.

Database Anomalies: Insertion, Deletion, and Modification

Fri, 16 Feb 2024 00:00:00 +0000

Insertion, Deletion, and Modification Anomalies Are Considered Bad

An insertion anomaly is a situation that arises when one is prevented from inserting data into a relation because the complete primary key is not available. No part of a primary key can be null. Harrington (2009) points out that insertion anomalies usually occur in first-normal form relations that do not exist in the higher normal forms.

Insertion anomalies occur because there is usually data about more than one entity in the relation. An example of customer, item, and orders will be used to show an example of an insertion anomaly.

Demystifying SQL Retrieval Queries A Step-by-Step Breakdown

Thu, 15 Feb 2024 00:00:00 +0000

How Is SQL Query Retrieved, and Conceptually, What Is The Order oF Executing Each of The Six Clauses?

SQL or the Structured Query Language described by Bowman, Emerson, & Darnovsky (1997) was proposed in 1970 by Dr. E. F. Codd at IBM and developed the SQL language over the next decade at research facilities and universities. IBM announced the first commercial SQL production database in 1981, called SQL/DS.

The database management system (DBMS) is a complex application software. Before discussing conceptually how an SQL retrieval query is executed by specifying the conceptual order of executing each of the six clauses, let's understand how a DBMS processes SQL queries at a high level.

SQL Join Types: Inner vs. Outer Join Operations Explained

Wed, 14 Feb 2024 00:00:00 +0000

How Does One Choose Between the SQL Right Join Inner vs. Outer in SQL?

An SQL Join is an operation of accessing the data from two or more tables or relations. In simple terms, a join occurs whenever multiple tables or relations appear in the FROM clause of a query, as described by Bhanuprakash, Nijagunarya & Jayaram (2014).

Any number of attributes or columns can be chosen in the SELECT clause. When two tables are joined, one must find the standard columns from both tables to join the tables with a relational operator. If a column has the same name in both tables, it must be qualified by the table name to avoid the uncertainty of which table the column’s data should be retrieved.

Attribute and Relationship Inheritance in EER Diagrams

Tue, 13 Feb 2024 00:00:00 +0000

The Mechanism of Attribute/Relationship Inheritance and Why it Useful

The enhanced entity-relationship (EER) diagram includes the principles of the entity-relationship diagram with the addition of some other concepts as described by Tupper (2011). The additional concepts include subclasses and superclasses, specialization and generalization, inheritance, and categories.

With entities in a logical model, there are often sub-groups that are of critical interest to the business area that is modeled. For example, let's look at the entity vehicle. Vehicle entities include cars, sports utility vehicles, hybrids, crossovers, and trucks. The vehicle would be a superclass, and the car, sports utility vehicle, hybrid, crossover, and trucks are subclasses.

Enterprise project management (EPM) takes into account the organizational processes that are in place, any technology that the company is using, and the company organization hierarchy or structure, which assists the company in devising a strategy for running many projects at once as described by Verzuh (2015)

Mapping EER Model Constructs to Relations in Your Database

Sat, 10 Feb 2024 00:00:00 +0000

The Options for Mapping EER Model Constructs to Relations

There are many ways of mapping the constructs from the EER model into the relational model. There are mapping of specializations or generalizations, shared subclasses, or multiple inheritance and categories.

Several options are available for mapping several subclasses that together form a specialization. There are two main options for map specializations. The first is to map the whole specialization or subclasses to one single table. The second is to map the specialization or subclasses to multiple tables. Each option is a variation that depends on the constraints on the specialization/generalization, as Elmasri (2015) described. There are a few options for mapping specialization or generalization, as Elmasri (2015) points out.

Object vs. Relational Databases: Key Design Differences

Fri, 09 Feb 2024 00:00:00 +0000

The main differences between designing relational and object databases**

Object databases and (ODB) relationships have three distinct differences: how relationships are handled, how inheritance is handled, and the timing of specifying operations in object databases compared to relational databases as described by Elmasri & Navathe (2015).

Relationships are handled differently between ODBs and RDBs. The ODB uses the Object Identifier commonly known as an OID. The OID reference is the relationship property, or reference attribute, that relates objects, as Elmasri & Navathe (2015) point out. OID references for a binary relationship can be declared in one direction or both directions depending on the required access needed. If the binary relations is specified in both directions, this is the same as creating a relational database constraint.

Cursors in Embedded SQL: Usage, Power, and Performance

Thu, 08 Feb 2024 00:00:00 +0000

The cursor and usage in embedded SQL

The SQL language, by default, uses set-at-a-time processing. While this is used in most SQL queries, sometimes there is a need to loop through the set and execute a stored procedure or many different SQL statements for each row fetched. SELECT statements that return more than one row can present a problem when embedding them in a program, as Harrington (2010) identified. The host language variables can only handle one value at a time, and the SQL command processor cannot work with the host language arrays. So, the cursor allows the host language to extract a row at a time for processing.

Understanding Parameter Types in Database Cost Functions

Wed, 07 Feb 2024 00:00:00 +0000

Different Parameter Types in Database Cost Functions and Their Information Storage

The cost function is part of the query cost optimization module of the database management system. Elmasri & Navathe (2015) indicate that the optimizer heuristic rules or query transformations are not the only dependencies used for cost optimization.

The cost-based optimizer will estimate and compare the cost of executing a query by taking advantage of different execution strategies and algorithms, and it then chooses the strategy with the lowest cost estimate.

Agile Scrum Communication: Essential Tools and Techniques

Sat, 20 Jan 2024 00:00:00 +0000

Enhancing Project Communication Essential Tools and Techniques in Agile Scrum

Our company is using Agile Scrum to manage the project. The project communication for Agile Scrum is different from normal project communication. There are a few Agile Scrum techniques for increasing communications. This post covers three. The daily stand-up, iteration planning, and demo review sessions.

The daily communication with team members is achieved during a morning stand-up, as Cooke (2010) describes. The standup is normally done standing up, so it will not last long, but on our team, many sit down. The standup is for team members to communicate and coordinate what’s going on, monitor progress, and identify any obstacles that may be inhibiting progress, as Cooke (2010) discusses. The scrum master on our team displays an electronic Scrum board on the large screen in the meeting room using Rally Development software, now known as Computer Associates Agile. The software enables teams to support work with organizational priorities, continuously communicate on all the project progress, and coordinate work across multiple teams and distributed sites in the spirit of enterprise agility as described by RallyDev (2017). The scrum master displays current stories, which are units of work defined for a sprint, and asks each team member to communicate three things at the stand-up that usually lasts fifteen to thirty minutes. First, what did you complete yesterday? Then, what do you plan to complete today? Finally, do you have any blockers? The scrum master's job is to be sure the team members have no roadblocks that get in the way of completing stories in a sprint, as Cooke (2010) points out. The scrum master facilitates the meeting, and anything outside of the task's status on the scrum board is held until the end of stand-up for further discussion. This is referred as putting that discussion in the parking lot. The parking lot items come up during communication of status unrelated to a story, topic, or issue a team member would like to discuss with the team.

Software Project Estimation: Top Tools and Techniques

Fri, 19 Jan 2024 00:00:00 +0000

A Summary of the two most important tools and techniques used in estimating software project

Estimating is attempting to look into the future and predict the time and money needed to produce a result, as Verzuh (2015) points out. Since an estimate is, well, an estimate, it can be wrong sometimes, and stakeholders normally don’t like when project estimates or budgets do not align with the final cost, as Verzuh (2015) points out.

Managing Project Risks Tools and Strategies from Experience

Tue, 16 Jan 2024 00:00:00 +0000

Here we summarize risk management in a project. Identify tools that can be used to assist in risk management

Most projects are put together and identify significant deliverables and milestones to be delivered in a project, as Wills & Governance (2015) discuss. The deliverables and milestones are normally identified at the start of the project. As a project moves through the deliverables and milestones, risks and issues arise, actions must be taken, and decisions must be made. Risk should be managed the same as the project as Wills & Governance (2015) point out.

Stakeholder Identification and Engagement for Project Success

Mon, 15 Jan 2024 00:00:00 +0000

How will you identify stakeholders? How will you keep your stakeholders engaged and informed?

** At first, stakeholder identification seems pretty straightforward – name the people who will affect the project or be affected. All too frequently, some very important stakeholders are forgotten.

How will you identify stakeholders? How will you keep your stakeholders engaged and informed?

There are many ways to identify the stakeholder. One can use organization charts or directories to look for stakeholders, as Measey (2015) points out. When gathering stakeholders, it can be best to create a stakeholder list of people who should be involved in product delivery. If previous projects exist around the same product, one may be able to leverage the stakeholders participating in past projects. Another way to identify stakeholders is to hold a brainstorming session to capture every name, organization, or type of stakeholder needed for the project. This kind of workshop can be a great way to identify stakeholders, as Measey (2015) points out.

IT Projects and Business Strategy: Why Alignment Matters

Sat, 13 Jan 2024 00:00:00 +0000

Why is it critically vital to support IT projects with a business strategy?

A project consists of a beginning and end; in many cases, projects are used to achieve strategic organizational goals. A company may use projects to innovate, move into a new business market or use a project to drive down cost within the organization as described by Verzuh (2015).

Information technology is critical to most thriving businesses today. Information technology, in many cases, is essential in assisting in automation or streamlining business operations. Categorizing information systems projects that deliver the greatest business benefits, organizations must develop an information system plan that is in line with the organizations overall high-level strategic plan. As Laudon & Laudon (2007) points out, the strategic plan provides the organization a road map. The plan contains a statement of corporate goals and specifies how information technology will support the attainment of those goals.

Project Success vs. Efficiency: Understanding the Difference

Wed, 10 Jan 2024 00:00:00 +0000

The Relationship between Project Success and Project Efficiency

Introduction

A project is created to have a start and a conclusion or end. At the end of the project, the project manager is released from the project or moves onto the next project as Serrador &Turner (2015) discuss. Currently there two competing measures referred to as project efficiency and project success. Project efficiency takes into the account the budget, scope and time, which project management philosophy refers to as the triple constraint or the golden triangle. A majority of the literature on project management identify the project ends when it is delivered to the customer.

Triple Constraint in Project Management: Time, Cost, Quality

Sun, 07 Jan 2024 00:00:00 +0000

The Intricate Dance of the Triple Constraint: Balancing Time, Cost, and Quality in Project Management

Imagine a project as a three-legged stool. Each leg represents a crucial element for its success: Time, Cost, and Quality. This interconnected trio, known as the Triple Constraint, forms the foundation of every project endeavor. As described by Verzuh (2015), effectively managing these variables dictates the project's outcome, and it's the project manager's responsibility to orchestrate this intricate dance.

IoT Security Threats: Smart Home Device Vulnerabilities

Tue, 31 Jan 2017 00:00:00 +0000

Internet Of Things Risks: Smart Home Device Security Threats

Abstract

The Internet of Things (IoT) devices connected to the Internet in 2015 is estimated to be five billion. This number is seen growing to twenty-five billion within the next five years and thought to be the third wave of the Internet boom as described by O’Brien (2015). This paper focuses on the security risks associated with smart home devices. Most consumers are unable to maintain smart home IoT devices. These device vulnerabilities are a safety hazard that motivated writing this paper. Weak authentication & authorization methods are security risks to IoT devices. Denial of service attacks (DoS) affects IoT device security and availability. The research includes the creation of a home network and sampling ten smart home IoT products. Vulnerability tests were conducted using system analysis software to determine if passwords are encrypted or clear text and to understand if a Denial of Service attack stopped the IoT device from providing service. Passwords were found to be clear text 60% of the time connecting from a web client to an IoT device. A DoS attack vulnerability test found 70% of the devices unusable. Ideas to resolve security issues would be adoption of an IoT device certification standard adopted by the industry IoT manufactures. Requirements to be put in place for manufacturers to release software updates through automated patching. The consumer’s smart home IoT security risk are growing as online device use explode, and IoT manufacturers must be held responsible for protecting consumers security and privacy.

In a comment today about the Empty Oracle Recycle Bin, A person wanted to know how one turns off or disables the Oracle Recycle Bin?In ORACLE 10G Release 1 there is a knob to turn to disable the behavior of recycling bin. The “_recyclebin” which defaults to TRUE. We can disable it by setting it to FALSE.

Command to disable that would be:

Emptying the Oracle Recycle Bin in Oracle 10g Release 2

Thu, 04 Jan 2007 00:00:00 +0000

Empty Oracle Recycle Bin

A new feature in Oracle 10g Release 2 was the Reycycle Bin. The recycle bin in the Oracle database is where all dropped objects reside. Underneath the covers the object are taking up the same space when they were created.

"DROP TABLE mytable", it doesn't really drop it. It instead renames it to e.g.: BIN$67815682942.

Dropped objects are not deleted they are just rename with a prefix of BIN$$. One can get access to the data in a dropeed table or even use a Flashback Query if you have this feature enabled on your version of Oracle.

Relink Oracle Database Software on a Unix/Linux RAC Cluster

Mon, 01 Jan 2007 00:00:00 +0000

Relink Oracle Database Software on Unix Linux RAC Cluster

Had problems with running Oracle RAC on a cluster on Redhat Release 3 AS. So we started the conversion to Redhat Release 4 AS. We run a 2 node RAC Cluster on iSCSI Lefthand Networks SAN. The Oracle software is installed on a lun on each machine and the database is on lun’s of RAW disk manged by ASM. This allows flexability by moving the luns from OS to OS and recompiling the Oracle binaries when we need to move the Oracle Cluster to a new version of the OS.
