Detects potential SpEL Injection exploitation, which may lead to RCE.
Detects when an account makes changes to the ingress or egress rules of a security group.
This can indicate that an attacker is attempting to open up new attack vectors in the account, that they are trying to exfiltrate data over the network, or that they are trying to allow machines in that VPC/Subnet to contact a C&C server.

Detects changes to the security groups associated with an Elastic Load Balancer (ELB) or Application Load Balancer (ALB).
This can indicate that a misconfiguration allowing more traffic into the system than required, or could indicate that an attacker is attempting to enable new connections into a VPC or subnet controlled by the account.

Detects changes to the security group entries for RDS databases.
This can indicate that a misconfiguration has occurred which potentially exposes the database to the public internet, a wider audience within the VPC or that removal of valid rules has occurred which could impact the availability of the database to legitimate services and users.

Detects suspicious SSH / SSHD error messages that indicate a fatal or suspicious error that could be caused by exploiting attempts
Detects suspicious DNS error messages that indicate a fatal or suspicious error that could be caused by exploiting attempts
Detects suspicious VSFTPD error messages that indicate a fatal or suspicious error that could be caused by exploiting attempts
Rule to detect the use of the SCX RunAsProvider ExecuteScript to execute any UNIX/Linux script using the /bin/sh shell.
Script being executed gets created as a temp file in /tmp folder with a scx* prefix.
Then it is invoked from the following directory /etc/opt/microsoft/scx/conf/tmpdir/.
The file in that directory has the same prefix scx*. SCXcore, started as the Microsoft Operations Manager UNIX/Linux Agent, is now used in a host of products including
Microsoft Operations Manager, Microsoft Azure, and Microsoft Operations Management Suite.

When IIS uses an old .Net Framework it's possible to enumerate folders with the symbol "~"
