The course and related CEH (Certified Ethical Hacker) materials detail several advanced features and evasion tactics:
Wrapping unauthorized protocols inside an encrypted SSH session.
To effectively defend a network, security professionals must understand how malicious actors attempt to bypass security controls. The LinkedIn Learning curriculum focuses on three primary defensive technologies and the methodologies used to test their resilience.

Using DNS queries to exfiltrate data or establish Command and Control (C2) channels. Because firewalls must allow DNS resolution, this traffic often passes unrestricted. IP Address Spoofing and Proxying
Evading IDS, firewalls, and honeypots requires a deep understanding of how these security measures work and the ability to think creatively. Here are some techniques used by hackers to evade these security measures: Intrusion Detection Systems (IDS) Using DNS queries to
In the landscape of modern cybersecurity, perimeter defenses serve as a critical shield against malicious traffic. For security professionals pursuing certifications like the Certified Ethical Hacker (CEH) or advancing their careers through platforms like LinkedIn Learning, mastering the mechanics of how attackers bypass these shields is essential.
