Assessment Title

Rule Text

The system must not have the finger service active.

Description

Discussion Text

The finger service provides information about the system's users to network clients. This information could expose information that could be used in subsequent attacks.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Checks

DISA STIG (Manual Reference)

If the "SUNWrcmds" package, containing the finger service executable, is not installed, this is not applicable.

# svcs finger
If the finger service is not disabled, this is a finding.

Remediation

Disable the finger service and restart inetd.
Procedure:
# svcadm disable finger
# svcadm refresh inetd
