Firewalls, VPNs, and traffic control are the mechanisms that determine what enters, leaves, and moves through a network. Understanding how they work — and how they fail — is essential for both offensive and defensive security. This article covers the fundamentals every cybersecurity professional must know.
Protocols are the rules that every network communication follows. HTTP, HTTPS, SSH, FTP, SMTP — every one of them has a specific vulnerability profile. This article breaks down the protocols every cybersecurity professional must know: what each does, how it works, and exactly where attackers look for weaknesses.
Before you can attack a network or defend one, you need to understand how data actually moves. Not in theory — in practice. This article breaks down the TCP/IP model and the OSI model: what they are, what each layer does, and exactly why every cybersecurity professional must understand them.
