Symantec Web Security Service

The Sumo Logic app for Symantec Web Security provides real-time insights into the web traffic and helps you to identify potential security threats. This app is based on a cloud-to-cloud Symantec Web Security Service source that collects Symantec Web Security access logs. With the Sumo Logic app for Symantec Web Security, you can:

• Monitor for web-based threats. Monitor the web traffic for potential threats using access logs generated by the Symantec Web Security Service.
• Detect and prevent malware infections. Search access logs for patterns of behavior that are indicative of malware infections. It also provides integrations with threat intelligence sources, which can help you to quickly identify potential malware infections and take necessary action to prevent them.
• Identify and block suspicious web activity. You can use the app to monitor suspicious web activity, such as requests to known malicious sites.
• Optimize web security policies. This app provides insights into web traffic that can help you to optimize web security policies. You can also use the app to identify areas where policies may be too restrictive or too permissive and make adjustments accordingly.

Collection configuration and app installation

Depending on the set up collection method, you can configure and install the app in three ways:

• Create a new collector and install the app. Create a new Sumo Logic Cloud-to-Cloud (C2C) source under a new Sumo Logic Collector and later install the app, or
• Use an existing collector and install the app. Create a new Sumo Logic Cloud-to-Cloud (C2C) source under an existing Sumo Logic Collector and later install the app, or
• Use existing source and install the app. Use your existing configured Sumo Logic Cloud-to-Cloud (C2C) source and install the app.

info

Use the Cloud-to-Cloud Integration for Symantec Web Security Service to create the source and use the same source category while installing the app. By following these steps, you can ensure that your Symantec Web Security Service app is properly integrated and configured to collect and analyze your Symantec Web Security Service data.

Create a new collector and install the app

To set up collection and install the app, do the following:

note

Next-Gen App: To install or update the app, you must be an account administrator or a user with Manage Apps, Manage Monitors, Manage Fields, Manage Metric Rules, and Manage Collectors capabilities depending upon the different content types part of the app.

1. Select App Catalog.
2. In the 🔎 Search Apps field, run a search for your desired app, then select it.
3. Click Install App.
   note

   Sometimes this button says Add Integration.

4. In the Set Up Collection section of your respective app, select Create a new Collector.
   1. Collector Name. Enter a Name to display the Source in the Sumo Logic web application. The description is optional.
   2. Timezone. Set the default time zone when it is not extracted from the log timestamp. Time zone settings on Sources override a Collector time zone setting.
   3. (Optional) Metadata. Click the +Add Metadata link to add a custom log Metadata Fields. Define the fields you want to associate, each metadata field needs a name (key) and value.
      • A green circle with a checkmark is shown when the field exists and is enabled in the Fields table schema.
      • An orange triangle with an exclamation point is shown when the field doesn't exist, or is disabled, in the Fields table schema. In this case, an option to automatically add or enable the nonexistent fields to the Fields table schema is provided. If a field is sent to Sumo that does not exist in the Fields schema or is disabled it is ignored, known as dropped.
   4. Click Next.
5. Configure the source as specified in the Info box above, ensuring all required fields are included.
6. In the Configure section of your respective app, complete the following fields.
   1. Field Name. If you already have collectors and sources set up, select the configured metadata field name (eg _sourcecategory) or specify other custom metadata (eg: _collector) along with its metadata Field Value.
7. Click Next. You will be redirected to the Preview & Done section.

Post-installation

Once your app is installed, it will appear in your Installed Apps folder, and dashboard panels will start to fill automatically.

Each panel slowly fills with data matching the time range query received since the panel was created. Results will not immediately be available but will be updated with full graphs and charts over time.

Use an existing collector and install the app

To set up the source in the existing collector and install the app, do the following:

Viewing Symantec Web Security Service dashboards

All dashboards have a set of filters that you can apply to the entire dashboard. Use these filters to drill down and examine the data to a granular level.

• You can change the time range for a dashboard or panel by selecting a predefined interval from a drop-down list, choosing a recently used time range, or specifying custom dates and times. Learn more.
• You can use template variables to drill down and examine the data on a granular level. For more information, see Filtering Dashboards with Template Variables.
• Most Next-Gen apps allow you to provide the scope at the installation time and are comprised of a key (_sourceCategory by default) and a default value for this key. Based on your input, the app dashboards will be parameterized with a dashboard variable, allowing you to change the dataset queried by all panels. This eliminates the need to create multiple copies of the same dashboard with different queries.
