How can companies reduce risk exposure through attack surface reduction?

Asked on Oct 17, 2025

Answer

Reducing risk exposure through attack surface reduction involves minimizing the potential entry points that attackers can exploit. This is achieved by implementing security controls that limit unnecessary access and harden systems against threats, as recommended by frameworks like the CIS Controls and NIST CSF.

Example Concept: Attack surface reduction focuses on identifying and eliminating unnecessary services, applications, and network protocols that could be exploited by attackers. This includes disabling unused ports, removing redundant software, enforcing least privilege access, and regularly updating systems to patch vulnerabilities. By reducing the number of exploitable points, organizations can significantly lower the likelihood of successful attacks.

Additional Comment:

Regularly conduct vulnerability assessments to identify and address new risks.
Implement network segmentation to isolate critical systems from potential threats.
Use endpoint protection solutions to monitor and control device configurations.
Educate employees on security best practices to prevent social engineering attacks.
