CCST Security Study Notes - Chapter 2
Network Security Concepts TCP/IP, the Transmission Control Protocol/Internet Protocol suite, underpins all internet communication. While it's fundamental for everyday internet functionality, it also has inherent weaknesses that attackers can exploit. Here are some common TCP/IP protocol vulnerabilities: IP Spoofing: This technique involves forging an IP address in a packet to impersonate a trusted source. Attackers can use IP spoofing to launch denial-of-service attacks (DoS) or gain unauthorized access to a network. Here's an example of IP spoofing to illustrate how it can be used in a cyberattack: Scenario: Imagine Sarah, a college student, wants to gain unauthorized access to the university's online grading system to change her grades. The grading system has security measures in place, and Sarah cannot access it directly with her student ID. IP Spoofing Attack: Target Identif...
