  24. Mapping for the Default Parameter Name to Actual Parameter in Device:
    Default Parameter Name Actual Parameter
    banner_name:

    banner_state

    cm-device-group-auto-sync

    Compliant or Non-Compliant is decided based on the below logic:

    In each of the cm device-group config, first it is checked whether “type sync-failover” is there. If it exists, then “auto-sync” value in the device is cross checked with the value defined in the Policy, if all match compliant, else non-compliant. Remediation happens only for Non-Complaints.
    dns_ip_address

    gateway_ip

    httpd-allow

    httpd-auth-pam-idle-timeout

    httpd-redirect-http-to-https

    httpd-ssl-protocol

    net-self-allow-service

    The Parameter is compliant or Non-Compliant is decided based on the key “allow-service”. In each net self config, it is checked if the value of allow-service in the device matches with the one defined in AppViewX. If all config matches, it is Compliant, else it is Non-Compliant. Remediation happens only for the config that are Non-Compliant. Only Default Values are supported (none, default, all) and no custom values are supported. Example for custom value is tcp:8844.
    ntp_ip_address

    ssh_inactivity_timeout

    sys-global-setting-gui-security-banner

    sys-global-setting-gui-setup

    sys-globalsetting-console-inactivity-timeout

    sys_search_dns

    syslog_param

    syslog_param

    Compliant or Non-Compliant is based on the points below:

    • If the IP and Port defined in Golden config match with the device, then compliant. Then, no action is required.
    • If Syslog Name, IP, or port defined in Golden config does not match, then it is non-compliant. Then, update the IP or port.
    • · If the Syslog Name and IP or port defined in the golden config do not match, then create a new Syslog config.
