The Juniper SRX Services Gateway must ensure access to start a UNIX-level shell is restricted to only the root account.


Overview

Finding ID Version Rule ID IA Controls Severity
V-223213 JUSX-DM-000113 SV-223213r960966_rule Medium
Description
Restricting the privilege to create a UNIX-level shell limits access to this powerful function. System administrators, regardless of their other permissions, will need to also know the root password for this access, thus limiting the possibility of malicious or accidental circumvention of security controls.
