Appendix S: SDL-Agile High-Risk Code

The following defines the highest risk code (at the time of writing) that should receive greater scrutiny if the code is legacy code and should be written with the greatest care if the code is new code.

  • Windows services and *nix daemons listening on network connections
  • Windows services running as SYSTEM or *nix daemons running as root
  • Code listening on unauthenticated network ports connections
  • ActiveX controls
  • Browser protocol handlers (for example, about: or mms:)
  • setuid root applications on *nix
  • Code that parses data from untrusted (non-admin or remote) files
  • File parsers or MIME handlers
