- * CIPSO - Commercial IP Security Option
- *
- * This is an implementation of the CIPSO 2.2 protocol as specified in
- * draft-ietf-cipso-ipsecurity-01.txt with additional tag types as found in
- * FIPS-188, copies of both documents can be found in the Documentation
- * directory. While CIPSO never became a full IETF RFC standard many vendors
- * have chosen to adopt the protocol and over the years it has become a
- * de-facto standard for labeled networking.
