My InfoTech Journal: Decoding the Networking Enigma: OSI vs. TCP/IP Reference Models

My InfoTech Journal: Decoding the Networking Enigma: OSI vs. TCP/IP Reference Models The OSI (Open Systems Interconnection) Reference Model and the TCP/IP (Transmission Control Protocol/Internet Protocol) Reference Model: The OSI Reference Model and the TCP/IP Reference Model are both conceptual frameworks used to understand and standardize how different networking protocols and technologies interact. Here are some areas of comparison: 1. Number of Layers: OSI Model : It consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and  TCP/IP Model : It has four layers: Network Interface, Internet, Transport, and Application. 2. L ayer Functionality: OSI Model : Tends to be more comprehensive and abstract, defining each layer's functions independently. TCP/IP Model : Reflects the actual implementation of the Internet and focuses on how protocols are used in practice. 3.

Fortifying the Digital Frontier: Unmasking Network Security Risks and Solutions

Fortifying the Digital Frontier:  Unmasking Network Security Risks and Solutions It has been a while since my last post. I have been busy with work and learning Microsoft PowerBI and Power Automate. These are very good tools for dashboard creation and automation. Very easy to learn and use. Kudos to Microsoft for coming up with these great tools! Fast forward, I have recently enrolled in a Master of Information Systems (MIS) program via Distance Education. I am excited to be an online distance education student. It has been a    very long time since I was a student. I know there will be adjustments needed from me… to be diligent, to be disciplined in balancing my work-studies-life, and to persevere to achieve my goal of getting my Master’s Degree. I have decided to share my research in  MyInfoTech Journal  hoping these information will also be able to help those researching for similar topics. Today, I am researching on the  Network Layer  and its Security Implications . The informatio

Information Security Tenets (The CIA Triad)

My InfoTech Journal:   Information Security Tenets The CIA Triad The   three tenets or fundamental principles of Information Security are  Confidentiality ,  Integrity , and  Availability .  This is also commonly known as the CIA Triad . The Information Security  programs refers to the controls designed and implemented to protect these three tenets:  Confidentiality ,  Integrity , and  Availability .   What is Confidentiality? Confidentiality ensures that private information remains private and that these private information can only be accessed or viewed by authorized individuals on need to know basis. Information Security controls must therefore be put in place to protect the data from unauthorized disclosure.  Examples of  Information Security controls  to ensure Data Confidentiality : Access Control List (ACL) Username and Password  Encryption  Two-Factor Authentication (Password, Token, PIN, Biometric, etc) What is Integrity? Integrity refers to the accuracy and completeness of t

My InfoTech Journal: Unpacking the OSI Model: Your Guide to Networking Layers

My InfoTech Journal: Unpacking the OSI Model: Your Guide to Networking Layers The OSI (Open Systems Interconnection) reference model is a way to understand how different parts of computer networks communicate. Each layer having a specific job. 1. Physical Layer: This is the actual hardware, like cables and switches. Example: Ethernet cables connect devices in a network. 2. Data Link Layer: Ensures data is sent and received without errors within a local network. Example: Ethernet frames help in local data transfer. 3. Network Layer: Manages data routing between different networks. Example: IP (Internet Protocol) routers guide data between your home and a website. 4. Transport Layer: Ensures data arrives reliably and in order. Example: TCP (Transmission Control Protocol) guarantees error-free data transfer. 5. Session Layer: E stablishes, maintains, and ends connections between devices. Example: Setting up a video call on Skype. 6. Presentation Layer: Translates data into a format that
