can someone share the default lantowan_general signature filter criteria?

CyberA

I inadvertently changed my lantowan_general IPS policy and want to revert it back to the default.

I looked at an earlier Entities.xml export I had but it shows the same settigns as the lantowan_strict policy which seems odd.

    <Name>lantowan_general</Name>
    <Description>A General policy for LAN to WAN Traffic</Description>
    <RuleList>
      <Rule>
        <RuleName>Migrate_def_filter_2</RuleName>
        <SignaturSelectionType>All Application</SignaturSelectionType>
        <CategoryList>
          <Category>All Categories</Category>
        </CategoryList>
        <SeverityList>
          <Severity>All Severity</Severity>
        </SeverityList>
        <TargetList>
          <Target>All Target</Target>
        </TargetList>
        <PlatformList>
          <Platform>All Platform</Platform>
        </PlatformList>
        <RuleType>Default Signature</RuleType>
        <Action>Recommended</Action>
      </Rule>
    </RuleList>
  </IPSPolicy>

Can someone share the default signature filter criteria for lantowan_general?

    CyberA,

    from the online guide:

    The device provides following pre-defined policies. You can directly use policies 1 to 6 without any modifications while policies 7 to 10 can either be used directly or, can be modified as per your requirements:
    1. DMZ TO LAN
    2. DMZ TO WAN
    3. LAN TO DMZ
    4. LAN TO WAN
    5. WAN TO DMZ
    6. WAN TO LAN
    7. generalpolicy
    8. lantowan strict policy
    9. lantowan general policy
    10. dmzpolicy
     
    I do not have the rest of the policies (7 to 10). Also, if you have edit the 9 in this case, only you have the required modification. You have 2 ways to adjust the current situation:
    • use the logs to understand which IPS ID is dropping your good traffic and adjust the IPS policy (do not delete it this time :-)
    • rollback to a previous backup

    It is recommended to always backup the configuration before any big changes are made.

    Luk,

    Appreciate the tips, will be setting up a daily backup to a local FTP server.

    FWIW, modifying the IPS is what got me into this mess as I changed a single signature default action under the 'Migrate_def_filter_2' rule which lives under the 'lantowan_general' policy. This ended up overwriting and deleting all of the earlier signatures from the default set for that rule.

    The key take-away is:

    • Backup first to have a fail-safe
    • Don't modify an existing rule for a single signature as it will overwrite the entire set
    • After creating the new ALLOW rule move it to the top of the policy list

    Still interested in what the default category, severity, target, platform was for this 'Migrate_def_filter_2' rule if someone who has and can share it, would be much appreciated. Thanks.
