Network Security Administrator iClass (E|NSA)
Duration:
5 Days
Overview:
The EC-Council's NSA certification looks at the network security in defensive view while the CEH certification program looks at the security in offensive mode. The NSA program is designed to provide fundamental skills needed to analyze the internal and external security threats against a network and to develop security policies that will protect an organization’s information. Students will learn how to evaluate network and Internet security issues and design and how to implement successful security policies and firewall strategies. In addition, they will learn how to expose system and network vulnerabilities and defend against them.
Audience
System administrators, Network administrators, and anyone who is interested in network security technologies
Prerequisites
This course is a prerequisite for the CEH program.
