Ensure SSL/TLS service profiles do not allow TLS 1.0 or 1.1

HighLevel 1Automatedpaloalto

Description

SSL/TLS service profiles back the management web UI, GlobalProtect portals/gateways and captive portal. FAILs if any profile sets min-version tls1-0 or tls1-1. Note: a profile left at the default may omit min-version from the export, so also review profiles in the GUI. Audited against the PAN-OS running configuration in set format: run 'set cli config-output-format set' then 'show config running' (or 'show' in configure mode) and save the output.

How it is checked

Audit method: Configuration pattern

Pattern: (?m)^set (?:shared |vsys (?:"[^"\n]*"|\S+) )?ssl-tls-service-profile (?:"[^"\n]*"|\S+) protocol-settings min-version tls1-[01]\b

How it is fixed

Fix method: Guidance or infrastructure patch

configure set shared ssl-tls-service-profile <profile> protocol-settings min-version tls1-2 set shared ssl-tls-service-profile <profile> protocol-settings max-version max commit GUI: Device > Certificate Management > SSL/TLS Service Profile > <profile> > Min Version = TLSv1.2.
