生成安全和网络策略的规则命中次数报告

Prev Next

概览

Cato提供了一个预定义报告模板,显示报告期间流量与策略规则匹配的次数。 这有助于识别可以移除的未使用规则,并优化规则配置以更好地匹配所需的流量范围。 规则的命中次数基于由该规则生成的事件数量。 如果规则设置为不生成事件,则命中次数为零。

您可以为这些策略生成命中次数报告:

  • Internet防火墙

  • WAN 防火墙

  • 网络规则

创建定期或一次性报告的模板,其中包括在定义的时间范围内包含的站点和SDP用户。 默认情况下,命中次数报告的预定义报告模板显示过去一周所有站点和SDP用户的流量和数据。

有关报告的更多信息,请参见 Cato 报告。

创建一个周期性的命中计数报告

Create a new recurring report by defining the Filters for the items included in the report, as well as the Schedule which defines how often the report is generated - every two minutes, daily, weekly, or monthly. Generated reports are stored in the Cato Cloud, and they can be automatically emailed or downloaded. The Schedule also defines the time range that is covered by each report.

You can select a mailing list of email addresses for the recipients, which can include Cato Management Application admins, and external users.

For more information about Mailing Lists, see Working with Mailing Lists.

To create a recurring report:

  1. From the navigation pane, select Home > Reports.

  2. From the Catalog tab, find and select the template you want to use to generate the report.

  3. Click Generate > Create Schedule.

  4. Enter a Report Name.

  5. (Optional) In Filters, select specific sites or users for the predefined report.

    By default, the predefined report includes all sites and users.

  6. Define when the report will be generated and sent:

    1. Select the Frequency.

    2. For Weekly and Monthly scheduled reports, in Every select the day that the report is sent.

    3. Select the timezone.

  7. Select the export format: PDF or CSV.

  8. In Subscriptions, select the Mailing List that receives the report.

    You can click New to create a new mailing list.

  9. Click Save Schedule. The report is added to the Saved Reports tab.

Generating a Recurring Report On Demand

Recurring reports are automatically generated based on their schedule settings. For example, a weekly report configured for Monday, is generated every Monday. You can also choose to manually generate a recurring report on demand, in which case the generated report uses the defined time range based on the current day. If an admin manually generates a weekly report on a Tuesday, the time range for the report is the previous 7 days starting from that Tuesday, regardless of the starting day of the recurring report. For more information about the time range of recurring reports, see Cato Reports.

To generate a recurring report on demand:

  1. From the navigation pane, select Home > Reports.

  2. From the Saved Reports tab, find the recurring report and click Generate Now.

  3. From the Generated PDFs tab, find the report and click Download.

创建一次性命中次数报告

您可以基于命中计数模板创建一次性报告。 您可以为报告中包含的项目定义过滤器。

To create a one-time report:

  1. From the navigation pane, select Home > Reports.

  2. From the Catalog tab, select the template you want to use to generate the report.

  3. Select Generate > Generate Now.

  4. Enter a Report Name.

  5. Define the relevant Filters for your report.
    These are specific to the report type.

  6. Define the Timeframe and Timezone of the report.

  7. Select the Format: PDF or CSV.

  8. Click Generate.
    The report is generated, and you can download it from the Generated tab.

了解命中计数报告

规则的命中次数基于由该规则生成的事件数量。 如果规则设置为不生成事件,则命中次数为零。

这些是命中计数报告中的部分:

  • 最多/最少规则

    • 匹配最多的规则 - 显示匹配次数最多的20个策略规则及各自的命中计数

    • 匹配最少的规则 - 显示匹配次数最少的20个策略规则及各自的命中计数

  • 规则命中计数 - 按优先顺序显示所有规则列表,其中包含为每个规则生成的事件数量、规则名称以及最近生成事件的时间戳
