During the enumeration phase of an attack, the attacker creates active connections to an organization's network environment and performs directed queries to gain additional information. In this course, we look at enumeration and the types of enumeration an attacker can perform. We also look at encryption and the technologies and protocols used. An ethical hacker is a person who attacks an organization’s security on behalf of its owners in order to discover vulnerabilities. Instead of taking advantage of these vulnerabilities, the ethical hacker reports them to the organization who can then put in place the appropriate countermeasures to protect themselves against malicious hackers. This course is the fourth in a series of courses which can used in preparation for the Certified Ethical Hacker 312-50 exam. The course has been developed in partnership with EC-Council and is based on their Ethical Hacking and Countermeasures course materials and labs.
