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

Password Security: What are the Best Practices for Password Security

My InfoTech Journal: Password Security  This article is just a reminder on the importance of Password Security . As we become more and more comfortable with using online services like banking, cloud drives for data repository, and other online services, we tend to be more relax and sometimes put our defences down. In most cases, we put our trust on the Service Provider’s security controls.  We oftentimes forget or tend to ignore the fact that these service providers are usual targets by cybercriminals and may one day fall victim to data breach and data leaks. Data leaks may include your account, password, and other personal information. We might not have control over the service provider’s security controls, but as End-Users we should at least take precautionary measures for the things we can control, most fundamental is to ensure a strong password for our accounts. Best Practices for Password Security  These are some best practices that can be useful to you. This article can also be a
