Adversaries may stop or disable services on a system to render those services unavailable to legitimate users. Stopping critical services or processes can inhibit or stop response to an incident or aid in the adversary's overall objectives to cause damage to the environment.(Citation: Talos Olympic Destroyer 2018)(Citation: Novetta Blockbuster)
Adversaries may accomplish this by disabling individual services of high importance to an organization, such as <code>MSExchangeIS</code>, which will make Exchange content inaccessible (Citation: Novetta Blockbuster). In some cases, adversaries may stop or disable many or all services to render systems unusable.(Citation: Talos Olympic Destroyer 2018) Services or processes may not allow for modification of their data stores while running. Adversaries may stop services or processes in order to conduct Data Destruction or Data Encrypted for Impact on the data stores of services like Exchange and SQL Server.(Citation: SecureWorks WannaCry Analysis)

Comments
AWS RDS generates events for database instances and includes the following event that may indicate that an adversary has attempted to stop a database instance.
RDS-EVENT-0087: The DB instance has been stopped
This mapping is given a score of Partial because it can't differentiate between an authorized and unauthorized stopping of the database instance.

Comments
The Amazon Inspector Best Practices assessment package can assess security control "Configure permissions for system directories" that prevents privilege escalation by local users and ensures only the root account can modify/execute system configuration information and binaries. Amazon Inspector does not directly protect against system modifications rather it just checks to see if security controls are in place which can inform decisions around hardening the system. Due to this and the fact the security control is only supported for Linux platforms, the score is Minimal.
