Cisco ASA: SNMP Group Object

Description

The Cisco ASA: SNMP Group Object test is used to check the properties of specific output lines from an SNMP group configuration.

The snmp_group_object element is used by an snmp_group test to define the name of the SNMP group to be tested.

The snmp_group_state element defines the different information that can be used to evaluate the result of a specific ‘snmp-server group’ ASA command. This includes the user name and the corresponding options.

SCAP

XCCDF

For cisco_asa.snmp_group_object cisco_asa.snmp_groups_priv artifacts, an XCCDF Value element is generated.

<Value
  id="xccdf_org.cisecurity.benchmarks_value_[ARTIFACT-OVAL-ID]_var"
  type="string"
  operator="[operator.value]">
  <title>[RECOMMENDATION-TITLE]</title>
  <description>This value is used in Rule: [RECOMMENDATION-TITLE]</description>
  <value>[value.value]</value>
</Value>

For cisco_asa.snmp_group_object cisco_asa.snmp_groups_priv artifacts, the XCCDF check looks like this.

<check system="http://oval.mitre.org/XMLSchema/oval-definitions-5">
  <check-export
