Network security specialists monitor computer networks for security threats or unauthorized users. They analyze security risks and develop response procedures. They determine who have access to which information, and then plan, coordinate and implement information security programs.
In addition, they develop and test software deployment tools, firewalls and intrusion detection systems. Using a multi-layered approach, they use their expertise and up-to-date knowledge to help protect against Web threats that facilitate cyber crime, including malware, phishing, viruses, denial-of-service attacks, information warfare and hacking.
