In order to properly assess a vulnerability, three aspects of the vulnerability must be taken into account:

  • Is the information system susceptible to a given flaw?
    • Millions of vulnerabilities exist. You must ascertain if your information system:
      • Meets the criteria where the vulnerability exists to include the specific version identified by the vendor
      • For example, version 1.01 of a piece of software may be vulnerable to an exploit, while version 1.02 is not
