Select the API Endpoints tab to view the API endpoints and information on the various metrics associated with each API endpoint. API discovery is based on requests to specific endpoints.

At the top there are three checkboxes which determine the data shown on this page.

• Inventory: These API Endpoints are defined per the user's API Definition and are known as API Inventory. They can also be discovered endpoints that you moved to Inventory.

• Discovered APIs: These API Endpoints are discovered by Console using AI/ML and are based on traffic to them. The discovered API limit is 5000 endpoints per application.

• Shadow APIs: These APIs are discovered but not in inventory.

The API Endpoints tab also provides a summary of all discovered endpoints for each domain. When you select a specific domain, schema and sensitive data are presented as learned for this specific domain. If multiple domains are selected, the presented schema is learned across all domains. You can see a summary of the following:

• Top Attacked APIs: Presents the top three API endpoints with the highest percentage of attacks over traffic per endpoint.

• Top Sensitive Data: Presents the top three sensitive types detected in maximum number of API endpoints. The widget represents only current state, not effected by selected time range.

• Total API Calls: Presents the distribution of API calls by response codes.

• Most Active APIs: Presents the top three API endpoints with the highest percentage of traffic over all detected API traffic for the load balancer.

The next section shows all of you API endpoints in one of two different forms. Use the Graph and Table buttons the view you want to see.

You can also select the Download API Spec option to download the API specifications in a machine-readable Swagger JSON file, and you have a button to Update Schema for changes you make in the Table view.

The following action menu (...) items are dependent on the contents in the API Category and Schema Status columns. These menu items will allow you to manage your API inventory. The table below shows the values in the two columns, the actions that are available, and the result of taking the action.

Click Update Schema to review and update the discovered schema changes you want to include in an inventory update. Schema changes occur when a discovered schema is different from the schema that is currently in the inventory. The number in parentheses shows the number of API endpoints with schema changes. Note that the update is limited to 10,000 bytes per endpoint.

API Category	Schema Status	Action	Result
Discovered Inventory	OpenAPI	Remove From Inventory	Move the endpoint to the Discovered Shadow category. The endpoint will be moved to Deprecated once the discovered data is deleted (due to purging after the defined time to live (TTL) of discovered data).
Inventory	OpenAPI	Remove From Inventory	Deprecate an endpoint that came from an API spec (Archive).
Discovered Inventory	Discovered	Remove From Inventory	Remove a discovered endpoint from inventory and will get the Discovered Shadow category. This endpoint will be removed from the table only after the discovered data is deleted (expired TTL).
Discovered Shadow	Discovered	Move to Inventory	Add a discovered endpoint to the inventory. The endpoint is added with an empty schema, so there will be a difference with the discovered schema, and you may want to update the schema (see next table entry).
Discovered Inventory	Discovered Not-Updated	N/A	Click Not-Updated or Update Schema to review and update the discovered schema changes you want to include in an inventory update.
Discovered Shadow	Discovered	Mark as Non-API	Archive this endpoint because it is not part of the API.
Discovered Shadow	OpenAPI	Move to Inventory	Move endpoint back to Discovered Inventory
Deprecated	OpenAPI	Move to Inventory	Unarchive an endpoint.
Non-API	Discovered	Mark as API	Unarchive an endpoint.

Select the Malicious Users tab to view trend and list of events flagged as malicious user activity.

The malicious users view shows a bar chart representing the trend of malicious user activity over a default or selected time frame. The view shows a graphical representation as well as a tiled list of users flagged as malicious (to the left side of the graph). Upon selection of a user entry from the left-side list, the graph on the right-side reflects that user's activity.

Malicious User Monitoring and Mitigation

The view also displays a timeline section beneath the graph where risk scores for a user over the selected time frame is displayed. The scores are categorized in terms of the severity of the events.

Malicious user mitigation is supported using the Block User option located on the top of the view. You can also use the Add to Allow List option to remove the user from the malicious users list.

Note: A malicious user is identified when a risk score is assigned to the user based on the user activity. A risk score is computed based on the malicious user detection configuration and this computation takes into account all the configuration parameters (such as login failure threshold and forbidden activity) enabled in the malicious user detection settings. Depending on the risk score, a threat level is attached to a malicious user and mitigation actions are applied based on the configuration set for each threat level. The risk score for a user is decayed over time, if no further suspicious activity is observed.

Select the Security Analytics tab to load security analytics view, which can be viewed in two ways: Events and Incidents. Both of these views will show data for the time frame specified to the right of the Events/Incidents selector.
