The Advanced Threat Scan Engine (ATSE) uses a combination of pattern-based scanning and heuristic scanning to detect document exploits and other threats used in targeted attacks.
Major features include:
Detection of zero-day threats
Detection of embedded exploit code
Detection rules for known vulnerabilities
Enhanced parsers for handling file deformities
Because ATSE identifies both known and unknown advanced threats, enabling ATSE may increase the possibility of legitimate files being flagged as malicious.
