Types Of Vulnerability Assessment And Methodologies

Vulnerability assessments are often carried out to help assure organizations are protected from well known vulnerabilities (low hanging fruit).

As the term implies a vulnerability assessment is the methodology used for identifying security loopholes within IT applications and infrastructure and their subsequent remediation. It involves robust scanning of components either by individual security experts or network security admins in an organization.

Vulnerability Assessment Categories

Depending on the areas of the infrastructure under review a vulnerability assessment can be classified into three broad types.

External Scans

Scanning those components of the IT ecosystem that directly face the internet and are accessible to external users. For instance, ports, networks, websites, apps, and other systems used by external users or customers.

Internal Scans

Finding loopholes in the internal network of an organization (not exposed to external scans) that may damage the enterprise network.

Environmental Scans

Environmental vulnerability scans focus on specified operational technology of an organization, such as cloud services, IoT, and mobile devices.

The methodology for vulnerability assessments include the following steps, regardless of whether it is done by different vulnerability assessment tools or manually.

  • Initial Planning – Identifying the specific area of the organization’s IT infrastructure to assess for bugs.
  • Scanning – Manual or automated scanning of the target areas for possible or potential security vulnerabilities, flaws, exploitable bugs, and false positives.
  • Analysis – Analyzing the detected vulnerabilities for their potential impact, suggesting remedies, and quantifying the bugs to mark their severity and urgency of remediation.
  • Remediation – Applying various security measures to fix glitches by introducing product updates or system upgrades.

Web Application Scanning

Scanning web applications for identifying known vulnerabilities in the app architecture either manually, using app security scanners, or by hiring professional web app scanning services who provide both automated and indepth manual assessments along with virtual patching services as well as False positive POC for all automated scanner findings.

Network Scanning

Scanning wired or wireless networks to identify and remedy potential security flaws.

Build Assessment

Analyzing software builds for any security or performance bugs that may cause trouble in the later stages.

Database Assessments

Host-based Scanning
