Network Security
Network security is a key part of modern information technology, directly tied to the principles and systems we explored throughout this course. At its core, network security includes strategies and tools designed to protect the integrity, confidentiality, and availability of data as it travels across networks. This directly connects to the fundamentals of information technology, where understanding how computers communicate and exchange data is essential. It evolved as computers shifted from isolated systems to interconnected devices, requiring protections against eavesdropping, unauthorized access, and attacks (Andress, 2020). Early computer networks relied on basic protocols with little built-in security. Early threats like eavesdropping, spoofing, and data tampering emerged. This is when network security grew into a discipline of its own, blending knowledge of computer architecture, operating systems, and cryptography (Shelly ...
