When your network is attacked, typical questions asked include: “how do we determine our
risk exposure?" and more importantly, "how do we determine which systems to address
first?”
In early 2018, two critical vulnerabilities were unleashed: Meltdown and
Spectre. Figura 1. Prioritize high-profile vulnerabilities
Malicious programs can exploit Meltdown and Spectre to get access to secrets stored in the
memory of other running programs. Nearly three billion systems globally were potentially affected
by the vulnerabilities, as both hardware and software providers scrambled to get patches into the
hands of their customers.
Ranking threats using scanned data in Vulnerability Response
Depending on the third-party integration you use, vulnerability data is scanned and imported into the
Vulnerability Response application using
APIs. It is then matched against your assets in the ServiceNowConfiguration Management Database (CMDB). The resulting
vulnerable items are assigned a risk score
based on multiple factors, including the severity of the vulnerability and the importance of the
affected asset. Figura 2. Risk score
The risk score is configurable and provides quick prioritization. All information about the
vulnerability (for example, what it is, how it was exploited, and how to remediate the threat)
is automatically pulled into Vulnerability Response from the National
Vulnerability Database (NVD), eliminating the need for manual research. The solution’s
configurable dashboards instantly show your organization’s overall vulnerability exposure.Figura 3. VR Dashboard
Automating the next steps
After you have identified and prioritized the most critical vulnerable items, Security Operations workflows automate several
of the next steps. Figura 4. State encoding workflowFor business critical vulnerable items, requests to approve automatic patching are sent
and the appropriate owners are notified. This eliminates the need to search for the on-call
analyst or manually decide which items count as “critical.”
Upon approval and completion of the patch, a second scan is automatically run to verify the
fix. Using prioritization, workflows, and automation, the most critical items are addressed
first.
