Adversaries may encode data with a 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 standard data encoding system that adheres to existing protocol specifications. Common data encoding schemes include ASCII, Unicode, hexadecimal, Base64, and MIME.(Citation: Wikipedia Binary-to-text Encoding)(Citation: Wikipedia Character Encoding) Some data encoding systems may also result in data compression, such as gzip.

| I&S-03 | Network Security | mitigates | T1132.001 | 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.
