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. Adoption / Use: OSI Model : Less commonly used in practice, but it is still valuab

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

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

Network Security: How to minimize the Risk of your Wireless Network

My InfoTech Journal: What you can do to minimize the risk of your wireless network? Access Points are usually targets for unauthorized access. You have to ensure that your access points are secured to prevent unauthorized access.  There are several ways of securing your wireless access points.  Here is a Security Tip from the US CISA. Change default password. Restrict access. Encrypt the data on your network. Protect your Service Set Identifier (SSID). Install a Firewall. Maintain Anti-Virus software.I Use file sharing with caution. Keep your access point software patched and up to date. Check your internet provider’s router or router manufacturers wireless security options. Connect Using Virtual Private Network (VPN). A more detailed discussion of this tip can be found in this post:   US CISA: Security Tip (ST 005-003) Securing Wireless Networks End Notes  US CISA: Security Tip Disclaimer   This article is a result of my personal research and is not a substitute for legal advise.  Ple

Network Security: How to Secure Your Network

My InfoTech Journal: Network Security  To set the context of this domain, I have here several definitions from different service providers. Network Security  refers to the practices of protecting computer network from intruders, including both wired and wireless connections. - US CISA Network Security  is any activity designed to protect the usability and integrity of your network and data. It includes both hardware and software technologies. Effective network security manages access to the network. It targets a variety of threats and stops them from entering or spreading on your network. - Cisco Network Security  combines multiple layers of defenses at the edge and in the network. Each network security layer implements policies and controls. Authorized users gain access to network resources, but malicious actors are blocked from carrying out exploits and threats. - Cisco Network Security  are measures taken to protect a communications pathway from unauthorized access to, and accidenta
