FortiSIEM Rules

Password Policy Enumeration

Rule ID


Default Status



Detects enumeration of local or global password policies using built-in commands.







Discovery consists of techniques an adversary may use to gain knowledge about the system and internal network. These techniques help adversaries observe the environment and orient themselves before deciding how to act. They also allow adversaries to explore what they can control and what’s around their entry point in order to discover how it could benefit their current objective. Native operating system tools are often used toward this post-compromise information-gathering objective.

MITRE ATT&CK® Techniques


Password Policy Discovery

Adversaries may attempt to access detailed information about the password policy used within an enterprise network. Password policies for networks are a way to enforce complex passwords that are difficult to guess or crack through. This would help the adversary to create a list of common passwords and launch dictionary and/or brute force attacks which adheres to the policy.

Linux Process Monitoring via FortiSIEM Agent



Remediation Guidance

No remediation guidance specified

Time Window

If the following pattern or patterns match an ingested event within the given time window in seconds, trigger an incident.

300 seconds

Trigger Conditions

If the following defined pattern/s occur within a 300 second time window.


SubPattern Definitions

SubPattern Name: Filter

This is the named definition of the event query, this is important if multiple subpatterns are defined to distinguish them.

SubPattern Query

This is the query logic that matches incoming events

eventType = "LINUX_PROCESS_EXEC" AND (procName = "chage" AND swParam CONTAIN " -l " OR procName = "cat" AND swParam REGEXP ".*/etc/pam\.d/common-password.*")

Group by Attributes

This defines how matching events are aggregated, only events with the same matching attribute values are grouped into one unique incident ID


Aggregate Constraint

This is most typically a numerical constraint that defines when the rule should trigger an incident

COUNT(*) >= 1

Incident Attribute Mapping

This section defines which fields in matching raw events should be mapped to the incident attributes in the resulting incident.

The available raw event attributes to map are limited to the group by attributes and the aggregate event constraint fields for each subpattern

 hostName = Filter.hostName,
procName = Filter.procName,
swParam = Filter.swParam
