CEH refers to Certified Ethical Hacking, a phenomenon that is designed to benefit security officers, auditors, security professionals, site administrators, and professionals responsible for the integrity of the enterprise network infrastructure. It has become increasingly important for the senior networking professionals and decision makers to understand each and every security aspect of a company to provide security solutions that are suitable for their company.

The services of a Certified Ethical Hacker are highly beneficial to an organization to test the security of its networks and to penetrate its systems. The CEH Training program certifies individuals in the specific network security discipline of ethical hacking from a vendor. The CEH training is conducted in a highly immersive environment where the participants are guided through a process of scanning, testing, hacking, and securing their own systems.

The candidates begin by understanding how perimeter defenses work, followed by training on how to go about scanning and attacking their own networks without harming the real network. They then learn how intruders escalate privileges and what steps can be taken to secure a system. The other topics covered include Intrusion Detection, Policy Creation, Social Engineering, Open Source Intelligence, Incident Handling and Log Interpretation.
