Ensure minimum SNMP version is set to V3 for agent access

MoyenneNiveau 1Automatiséef5-bigip

Description

To disable the usage of weak SNMP protocols FAILs if any SNMP v1/v2c community (community-name) is configured under sys snmp; define SNMPv3 users instead. Audited against tmsh output with defaults shown: save the concatenated output of 'tmsh list auth password-policy all-properties', 'tmsh list auth source all-properties', 'tmsh list auth remote-user all-properties', 'tmsh list auth radius all-properties', 'tmsh list sys httpd all-properties', 'tmsh list sys sshd all-properties', 'tmsh list sys global-settings all-properties', 'tmsh list cli global-settings all-properties', 'tmsh list sys ntp', 'tmsh list sys snmp all-properties', 'tmsh list sys syslog' and 'tmsh list net self all-properties'. Patterns are scoped to the named top-level block.

Motif: (?m)^sys snmp \{\n(?:[ \t]+[^\n]*\n)*?[ \t]+community-name \S+

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

tmsh modify sys snmp communities delete { <community> } tmsh modify sys snmp users add { v3user { username v3user auth-protocol sha auth-password <pw> privacy-protocol aes privacy-password <pw> security-level auth-privacy } } tmsh save sys config # CIS guidance: 1-Login to Configuration utility 2- Go to System > SNMP > Agent > SNMP Access (v1, v2c) : Select all listed entries and click "Delete" 3-Go to System > SNMP > Agent > SNMP Access (v3) : Make sure there is one entry at least , otherwise create one.
