Out of band data can be used for IDS evasion
| tcp-oob-sent (5378) |
Description:
Out of band (OOB) data is used by a few rare network programs to send urgent message data at a higher priority than regular data. An attacker could misuse OOB data to evade intrusion detection systems or execute some Windows denial of service attacks.
Consequences:
Bypass Security
Remedy:
Examine the connection's destination port and determine if use of OOB data is normal for that service. If that service does not normally use OOB data, an attack may be in progress. Inspect the target system for signs of compromise.
