As a follow on to my article on whether AI can be used in Networking, this post dives in deeper to a question of will humans still be involved? And if so, how do we upskill that human expertise? To successfully integrate AI into network automation while ensuring human expertise is maintained, organizations and IT […]

Windows Firewall allows you to control the traffic entering and leaving your system through various rules. You can create and configure firewall rules to permit or block specific network activities. Below are some examples of Windows Firewall rules, including inbound and outbound rules: Example 1: Allow Inbound Traffic on a Specific Port (e.g., HTTP –

A great question in my two day Security class recently. The physical layer (Layer 1) of the layered model is responsible for the transmission of raw data bits over a communication medium. Although it is often considered more secure due to its reliance on physical components, it is still vulnerable to a variety of threats.
