Delete obsolete and expired hardware vulnerability assessments

Set up automatic deletion of obsolete or expired assessment records.

Before you begin

Role required: admin

About this task

Configure the age of obsolete or expired assessments to be cleaned.

  • Obsolete assessments: Invalid assessments, which have been ignored or the associated vulnerable items (VITs) are closed for more than two years.
  • Expired assessments: If you update the firmware version of a device, the existing assessments based on the previous firmware version become invalid and are considered as expired assessments. You can delete expired assessments, which are older than a month. However, you must perform new vulnerability assessments for the devices with an updated firmware version.

Procedure

  1. Navigate to All > System Data Management > Data Management Policies.

  2. Search for and select the sn_vul_analyst_firmware_vulnerability_assessment policy.

  3. Select the Active check box and configure clean-up rules according to your requirement.

    Configure the age in clean-up rules 1, 2, and 3, after which the obsolete and expired assessments are deleted:

    • Rule 1: Delete firmware vulnerabilities assessment whose VIT is closed since 2 years(based on last update date on VIT associated).
    • Rule 2: Delete firmware vulnerabilities assessment which are ignored since 2 years (based on created date).
    • Rule 3: Delete firmware vulnerabilities assessment which are expired since 1 month (based on last update date).
    • Select Update.
