Check: AADC-NM-000143
A10 Networks ADC NDM STIG:
AADC-NM-000143
(in version v1 r1)
Title
The A10 Networks ADC must restrict management connections to the management network. (Cat II impact)
Discussion
Remote administration is inherently dangerous because anyone with a sniffer and access to the right LAN segment could acquire the device account and password information. With this intercepted information they could gain access to the infrastructure and cause denial of service attacks, intercept sensitive information, or perform other destructive actions.
Check Content
Ask the device administrator what the subnet assigned to the management network is and which access-list is used to restrict management traffic. Review the device configuration. The following command displays a configured access-list: show access-list [ipv4 | ipv6] [acl-id] If no access list for the management network is configured, this is a finding. If the access list for the management network does not restrict traffic solely to the management network, this is a finding. The following command displays information about the management interface: show interface management If the access list is not applied to the management interface, this is a finding.
Fix Text
Configure an ACL or filter to restrict management access to the device from only the management network. The following commands configure an access control list that only allows traffic from the management network and logs denied traffic: access-list [acl-num] permit access-list [acl-num] permit source-ipaddr {filter-mask | /mask-length} access-list [acl-num] deny any log Note: The source-ipadd and mask must be the subnet used for the management network. The following commands apply the ACL to the management interface: interface management access-list [acl-num] in Note that acl-num is the number assigned to the ACL configured above.
