cyberstrikeus 2.2.11 Ensure Samba is not installed (Automated)
Profile
- Level 1 - Server
- Level 1 - Workstation
Description
The Samba daemon allows system administrators to configure their Linux systems to share file systems and directories with Windows desktops. Samba will advertise the file systems and directories via the Server Message Block (SMB) protocol. Windows desktop users will be able to mount these directories and file systems as letter drives on their systems.
Rationale
If there is no need to mount directories and file systems to Windows systems, then this service should be deleted to reduce the potential attack surface.
Audit Procedure
Command Line
Run the following command to verify samba is not installed:
# dpkg-query -s samba &>/dev/null && echo "samba is installed"
Nothing should be returned.
Expected Result
No output (empty result).
Remediation
Command Line
Run the following command to remove samba:
# apt purge samba
