Security planning

The product architecture handles and provides security at various levels, as described in the following sections:

Data transfer

The product can securely transfer data:

• Between various product components
• From product components to external system components. External systems include all products integrated with TrueSight IT Data Analytics (or IT Data Analytics) and PATROL for IT Data Analytics. For more information about the supported external systems, see Integrating.

For more information about the default communication ports and protocols, see Communication ports and protocols.

User authentication and authorization

• Users assigned an administrator role can configure user authentication and role-based access control (RBAC) from the IT Data Analytics Console. For more information, see User roles and permissions.
• User authorization is defined by the data access control setting that allows granular control over functions and data access for different users. For more information, see Managing user groups in IT Data Analytics.

Credentials

The following types of credentials are stored in encrypted form:

• IT Data Analytics user credentials
• SMTP email credentials
• ProactiveNet (or TrueSight Infrastructure Management) server credentials
• Credentials specified as part of credential profile creation and data collector creation

Credentials used for data collection are stored in encrypted form and are decrypted by the Collection Station or the Collection Agent just before passing the credentials to the external system for authentication. The product does not store or transfer the password in plain text. But the password is not encrypted when passed from the browser to the Console Server; to ensure complete security you need to enable security for the Console Server. For more information, see Enabling security for the Console Server and Search components.

Cross-site request forgery (CSRF) checks

IT Data Analytics prevents CSRF attacks by checking the HTTP header, called as Referer, of the incoming HTTP request. This header is present in the requests that come from browsers. All invalid requests return a HTTP 403 response. The CSRF check is controlled by the check.csrf property in the olaengiveService.properties file. 

By default, the CSRF checks do not filter out the following requests from accessing the product:

• Requests that are generated by CLI commands.

• Requests that are generated by typing the URL in the address bar of the browser.

• Requests in which the Referer matches the IT Data Analytics server host name.

• Browser requests in which Referer matches any of the following regular expressions: 

  Regular expression	Description
  ^http(s)?://127.0.0.1:(9797|9443)/.*	Any HTTP or HTTPS referrer with IPV4 loopback address as 127.0.0.1 and Port is either 9797 or 9443
  ^http(s)?://\[::1\]:(9797|9443)/.*	Any HTTP or HTTPS referrer with IPv6 loopback address as ::1 and Port is either 9797 or 9443
  ^http(s)?://localhost:(9797|9443)/.*	Any HTTP or HTTPS referrer with localhost and Port is either 9797 or 9443
