Adversaries may encode data with a non-standard data encoding system to make the content of command and control traffic more difficult to detect. Command and control (C2) information can be encoded using a non-standard data encoding system that diverges from existing protocol specifications. Non-standard data encoding schemes may be based on or related to standard data encoding schemes, such as a modified Base64 encoding for the message body of an HTTP request.(Citation: Wikipedia Binary-to-text Encoding) (Citation: Wikipedia Character Encoding)

| I&S-03 | Network Security | mitigates | T1132.002 | Non-Standard Encoding |
Comments
This control provides for monitoring, encrypting, and restricting communications between environments. Network intrusion detection and prevention systems that use network signatures to identify traffic for specific malware or uncommon data flows can be used to mitigate activity at the network level.

Comments
This control provides for the implementation of defense-in-depth network security controls for securing the cloud environment. Network intrusion detection and prevention systems that use network signatures to identify traffic for specific malware or uncommon data flows can be used to mitigate activity at the network level.
