How to Conduct a Vulnerability Assessment in a Remote Work Environment

Remote work brings flexibility, but it also opens the door to new security risks. With employees connecting from home networks, using personal devices, and accessing sensitive data outside the office, the need for regular vulnerability assessments has never been more important. Here’s how to do it right.

1. Start with an Inventory

Before assessing anything, know what you’re working with. Make a complete list of:

• Devices accessing your network (laptops, tablets, smartphones)

• Operating systems and applications

• Cloud services and tools used for communication or collaboration

This gives you a clear picture of what needs protection.

2. Check for Unpatched Software

Outdated software is one of the biggest security risks. Use automated tools to identify:

• Missing operating system updates

• Outdated applications

• Unpatched third-party software

Make patch management part of your regular routine to reduce the chance of exploitation.

3. Analyze Access Controls

Remote work can blur the lines of who has access to what. Double-check:

• User privileges (are employees only accessing what they need?)

• Multi-factor authentication (MFA) on all accounts

• VPNs or secure gateways in place for remote access

Tight access control limits exposure if a device is lost or compromised.

4. Scan for Vulnerabilities

Use trusted tools like Nessus, OpenVAS, or Qualys to perform vulnerability scans across your systems. Make sure your scans cover:

• Endpoint devices

• Cloud environments

• Remote desktop protocols

• Web applications

Look for weak configurations, open ports, and known vulnerabilities.

5. Assess Third-Party Risks

Remote teams often rely on third-party platforms. Evaluate:

• Which vendors have access to your data

• Their security certifications or audits

• How data is transmitted and stored between systems

Even if your network is secure, a weak vendor link could open the door for attackers.

6. Document and Prioritize

Once you've identified risks, assign severity levels and create an action plan. Prioritize high-risk vulnerabilities that impact critical systems or user data.

• High: Patch immediately

• Medium: Schedule within days

• Low: Monitor and address during routine maintenance

7. Test and Repeat

A one-time assessment won’t cut it. Schedule vulnerability assessments at regular intervals or after any major system change. Always test remediation efforts to confirm fixes were successful.

Final Thoughts

Remote work isn’t going away, and neither are the risks. Conducting regular vulnerability assessments helps you spot weak points before attackers do. If your business lacks the tools or in-house expertise, consider partnering with a cybersecurity service provider like SafeAeon, who can help strengthen your security while your team focuses on getting work done anywhere.
