## Symptoms

- * Vulnerability Assessment and Penetration Testing (VAPT) deep scans fail or return incomplete results when the scanner connects using a user account with a UID other than 0.

* <br />

  The SSH-based scan fails or produces partial output.
* Typical behavior includes permission errors when accessing system resources, for example:

  `
  Scanner logs in as user: nessus_scan`  
  ` ?`  
  ` ??? cat /etc/shadow ? Permission denied`  
  ` ??? rpm -qa ? Partial results`  
  ` ??? cat /proc/1/maps ? Permission denied`  
  ` ??? read /etc/cron.d/ ? Permission denied`  
  ` ??? check SUID binaries ? Incomplete results
  `

## Cause

The scanner used a non-privileged (non-root) user account.

Deep scans require elevated permissions to access critical system files, processes, and configuration data. Without sufficient privileges, the scanner cannot perform all required checks.
