Windows compliance checks
Windows compliance checks were developed by Prisma Cloud Labs. They can be enabled in your host compliance policy.
Create Windows host compliance rules in Defend > Compliance > Hosts. In the new rule dialog, select Windows host from the Types drop-down list.
The following checks are supported:
- 200001: Verify Windows Defender antivirus is running
Microsoft’s built in Windows Defender antivirus service is running.
- 200002: Verify Windows Defender antivirus is enabled
Microsoft’s built in Windows Defender service antivirus, anti-malware, and anti-spyware features are enabled
- 200003: Verify Windows Defender always-on protection is enabled
Always-on protection consists of real-time protection, behavior monitoring, and heuristics to identify malware based on known suspicious and malicious activities.
- 200004: Verify antivirus signatures match defined frequency
Windows antivirus signatures are overdue based on your frequency policy.
- 200005: Verify antivirus signatures are up-to-date
Windows antivirus signatures list must be updated within the last 14 days. If 14 days elapse without an update, signatures are stale. This interval is required to be effective against current threats.
- 200006: Verify anti-spyware signatures match defined frequency
Windows anti-spyware signatures are overdue based on your frequency policy.
- 200007: Verify anti-spyware signatures are up-to-date
Windows anti-spyware signatures list must be updated within the last 14 days. If 14 days elapse without an update, signatures are stale. This interval is required to be effective against current threats.
- 200201: Verify Windows Defender Control Flow Guard (CFG) is enabled
Control Flow Guard (CFG) is a platform security feature that combats memory corruption vulnerabilities. By placing tight restrictions on where an application can execute code, CFS makes it harder for exploits to execute arbitrary code through vulnerabilities, such as buffer overflows. This check is applicable to Windows Server 2019 only.
- 200202: Verify Windows Defender Data Execution Prevention (DEP) is enabled
Data Execution Prevention (DEP) monitors memory to stop malicious code from running. It monitors all processes and services and stops a program if it isn’t running correctly in memory. This check is applicable to Windows Server 2019 only.
- 200203: Verify Windows Defender Address Space Layout Randomization (ASLR) is enabled
Address space layout randomization (ASLR) prevents exploitation of memory corruption vulnerabilities. It prevents an attacker from reliably jumping to an exploited function in memory by randomly arranging the position (address) of the stack, heap, and loaded libararies. This check is applicable to Windows Server 2019 only.
- 200300: Verify Windows Firewall public profile is enabled
This setting is applied when a connection to a domain is made through a public network, such as at an airport, hotel, or coffee shop. Since the security of these networks is unknown and not really controlled by the user running the computer, it is suggested that the Public network profile of settings be more restrictive than either the Domain network or Private network.
- 200400: Verify Windows Update is enabled
Windows Update is a service which automates downloading and installing Microsoft Windows software updates.
- 200401: Verify Windows Update is set to automatically install
Verify that Windows is configured to automatically download and install updates at a regular interval.
