Vulnerability and risk assessments

  • 6 minutes

Sometimes IT teams need to evaluate systems for vulnerabilities and risks in addition to strategically setting up proactive controls and resilient infrastructure. For example, adopting a new technology like artificial intelligence (AI) might exacerbate existing vulnerabilities or create new security risks if IT professionals don't carefully consider its impact. Because cyberthreats like phishing, malware, and ransomware deliberately seek and target known vulnerabilities, closing existing security gaps is a critical responsibility for IT professionals.

Organizations like schools routinely perform two special types of assessments to evaluate security measures:

  • Vulnerability assessments
  • Risk assessments

Vulnerability assessment

NIST defines a vulnerability assessment as "a systematic examination of an information system or product to determine the adequacy of security measures, identify security deficiencies, provide data from which to predict the effectiveness of proposed security measures, and confirm the adequacy of such measures after implementation."

A vulnerability assessment involves two interrelated activities:

  • Scanning systems, hardware, and networks to identify vulnerabilities.
  • Prioritizing identified vulnerabilities according to the potential for exploitation.

Vulnerability assessments help IT professionals respond appropriately to threats as well as act on the most serious vulnerabilities first. This type of assessment should provide clear guidance on what needs attention in a computing environment and where on the list of priorities the issues lie.

Risk assessment

Another component of an overall, well-managed Risk Management Strategy is a systemwide risk assessment. A risk assessment is a comprehensive evaluation that delves deeper into an organization's security posture by considering the broader context of potential threats and their impact.

A risk assessment involves:

  • Examining the organization's assets.
  • Identifying potential threats and vulnerabilities.
  • Assessing potential impact of threats and vulnerabilities on operations.
  • Prioritizing mitigation efforts based on severity and potential consequences.

While a vulnerability assessment provides a snapshot of potential weaknesses, a risk assessment provides a more holistic view of the organization's overall risk landscape and guides strategic decision-making to mitigate those risks effectively.

Assessing risks and vulnerabilities

K12 SIX developed a self-assessment tool that you can use to evaluate your school's current security posture, risks, and vulnerabilities. The tool includes questions based on the widely recognized functions of school IT Teams from the National Institute of Standards and Technology (NIST) Cybersecurity Framework.

Additionally, depending on your subscription, Microsoft has a variety of offerings to help you identify risk and vulnerability within Microsoft Defender XDR.

  • Microsoft Copilot for Security: Microsoft Copilot for Security can reduce vulnerability assessments from minutes to seconds, while providing a list of impacted products and services, related threat intelligence and threat actors, and how you can mitigate them in your own environment.

  • Microsoft Defender for Endpoint: For Microsoft Defender for Endpoint Plan 2 customers, seamlessly enhance your vulnerability management program—without the need for additional agents—using the Defender Vulnerability Management add-on.

  • Microsoft Defender for Cloud: For Microsoft Defender for Cloud customers, get agentless vulnerability management for servers, containers, and container registries with Defender Vulnerability Management—natively integrated within Defender for Cloud.

  • Microsoft Defender Vulnerability Management: For other customers, complement your existing endpoint detection and response (EDR) solution with the Microsoft Defender Vulnerability Management standalone offering.

Next steps

  1. Take a moment to complete the K-12 SIX Cybersecurity Self-Assessment. Just like the CISA recommendations you learned about, the assessment highlights steps to take to strengthen your school's cybersecurity.
  2. When you finish answering all the questions, you receive a cybersecurity risk rating for your school, a list of critical issues that must be addressed, and priority considerations. Save or print the results for use later and note any key findings and issues.
