Description:	Adversaries may attempt to get a listing of security software, configurations, defensive tools, and sensors that are installed on a system or in a cloud environment. This may include things such as firewall rules and anti-virus. Adversaries may use the information from Security Software Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.
Tactics:	Discovery
Data Sources:	Command: Command Execution, Firewall: Firewall Enumeration, Firewall: Firewall Metadata, Process: OS API Execution, Process: Process Creation
Platforms:	Azure AD, Google Workspace, IaaS, Linux, macOS, Office 365, SaaS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may employ a known encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol. Despite the use of a secure algorithm, these implementations may be vulnerable to reverse engineering if secret keys are encoded and/or generated within malware samples/configuration files.
Tactics:	Command and Control
Data Sources:	Network Traffic: Network Traffic Content
Platforms:	Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may communicate using OSI application layer protocols to avoid detection/network filtering by blending in with existing traffic. Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and server.
Tactics:	Command and Control
Data Sources:	Network Traffic: Network Traffic Content, Network Traffic: Network Traffic Flow
Platforms:	Linux, macOS, Windows
