    PoliciesSecurityPolicy Optimizer displays:
    • New App Viewer—New cloud applications downloaded from the Application Control Engine if the firewall has a SaaS Security subscription.
    • Rules Without App Controls—Rules that have the application set to any, so you can identify port-based rules to convert to application-based rules.
    • Unused Apps—Rules that include applications that have never matched the rule.
    • Rule Usage—Rule usage information over different periods of time, including rules not used over different periods of time.
    Field
    Description
    Name
    The name of the Security policy rule.
    Service
    Any services associated with the Security policy rule.
    Traffic (Bytes, 30 days)
    Traffic (30 days)—The amount of traffic in bytes seen during the last 30-day period.
    A longer time period would result in the oldest rules remaining at the top of the list because they are likely to have the most cumulative traffic. This can result in newer rules being listed below older rules even if the newer rules see heavy traffic.
    Apps Allowed
    The applications that the rule allows. Open the Application dialog, from which you can add and delete applications on the rule.
    Application
    (New App Viewer only) The applications that the rule allows.
    Apps Seen
    The number of applications seen on the rule. Click the number to open the Applications & Usage dialog, which enables you to compare the applications configured on the rule against the applications seen on the rule and to modify the applications.
    Day with No New Apps
    The number of days since the last new application was seen on the rule.
    Compare
    Opens the Applications & Usage dialog to compare the applications configured on the rule against the applications seen on the rule and modify the rule.
    (Rule Usage) Last Hit
    The most recent time that traffic matched the rule.
    (Rule Usage) First Hit
    The first time that traffic matched the rule.
    (Rule Usage) Hit Count
    The number of times that traffic matched the rule.
    Modified
    The date and time that the rule was last modified.
    Created
    The date and time that the rule was created.
    Timeframe
    The time period (number of days) for which data is displayed.
    Usage
    Displays:
    • Any (all) rules on the firewall over the specified Timeframe, regardless of whether traffic matched the rules (used rules) or not (unused rules).
    • Unused rules that traffic has not matched over the specified Timeframe.
    • Used rules that traffic has matched over the specified Timeframe.
    Exclude rules reset during the last xx days
    Does not display rules for which you Reset Rule Hit Counter within the specified number of days (from 1-5,000 days). For example, this enables you to examine older rules that have not matched traffic over a Timeframe while excluding newer rules that may not have had time to match traffic.
    Reset Date
    The last date on which the rule’s hit counter was reset.
