To establish an effective external vulnerability scanning program, consider the following:
-
Define the Scope: Identify the systems, networks, and applications that are publicly accessible and need to be included in the scan. This could include your organization's website, email servers, or any other systems that can be accessed over the internet.
-
Choose the Right Tool: There are several vulnerability scanning tools available, both open-source and commercial. Choose a tool that fits your requirements in terms of ease of use, cost, and effectiveness. Reach out to your Customer Success Manager for Secureframe’s recommended external vulnerability scanner providers.
-
Configure and Run: Define the scope of the scan within the tool. Schedule the scan to run during a time when your system is not under heavy use.
-
Analyze the Results: Review the results of the scan, including vulnerabilities identified and their associated severity and potential impact. Prioritize the vulnerabilities based on severity and importance of the affected systems.
-
Remediation: Work with the relevant teams within your organization to patch the vulnerabilities or implement other remediation measures. This could involve updating software to a newer version, reconfiguring settings, or making changes to firewall rules. Document the remediation efforts in your organization’s ticketing tool.
-
Re-Scan: After the vulnerabilities have been addressed, re-run the scan to confirm that the remediation has been successful and that no new vulnerabilities have been introduced in the process.
-
Regular Scanning: Vulnerability scanning should be a recurring activity. New vulnerabilities can be introduced anytime systems are updated or configurations are changed. Regularly scheduled scans should be a part of your organization's routine cybersecurity practices.
- Compliance Reporting: If your organization is subject to compliance requirements or regulations that require vulnerability scanning, such as SOC 2 or PCI DSS, you will also need to produce reports from your scans to demonstrate compliance.
