What is a security researcher?

A security researcher keeps up-to-date on all the latest developments in threats to computer software and networks. These threats include different types of malware, such as computer viruses, malicious software and scripts, and direct attacks on a network. The main duties of a security researcher are to investigate existing types of malware, analyze their capabilities, and attempt to predict new forms of malware to develop appropriate security responses. They may reverse engineer malware or test security systems.
