Setting ASLR Status on Unix Devices via SanerCVEM

Objective

To guide users through the process of creating a job in SanerCVEM that sets the ASLR (Address Space Layout Randomization) status on Unix-based systems. This helps enhance system security by randomizing memory address allocations.

Need for This Task

ASLR is a critical security feature that makes it harder for attackers to predict the location of processes and libraries in memory. Setting ASLR status ensures that systems are protected against certain types of exploits. Using SanerCVEM to automate this configuration allows administrators to enforce consistent security policies across multiple Unix endpoints.

Form Field Explanations

- Operating System Family: Select "Unix" to target Linux/Unix systems.

- Action: Choose "Set ASLR Status" to configure ASLR settings.

- Permanent or Temporary: Specify if the change is temporary or permanent.

- ASLR Status Value: Select 0 (disabled), 1 (enabled), or 2 (fully enabled).

- Response Name: Provide a name for the job (e.g., "set ASLR").

- Response Description: Describe the purpose of the job.

- Target: Select the endpoint(s) where the ASLR status should be applied.

Results: Before and after the modifications from SanerCVEM

Conclusion

By using SanerCVEM to set ASLR status, administrators can improve the security posture of Unix-based systems. This centralized approach ensures consistent application of memory protection policies and reduces the risk of exploitation.
