System Hardening is the Preemptive Strike to Thwart Zero-Day Exploits

Key Points Contributing to System Hardening for Preempting Zero-Day Exploits

  • Decreases security risk by eliminating potential attack vectors.
  • Adopting system hardening best practices.
  • System hardening identifies, closes, and controls weak points and vulnerabilities.

In the ongoing war against cybercrime, an enterprise must have a battle plan that assumes a continual posture of assessment and vigilance. With cloud and perimeter expansion, the attack landscape is growing vast, requiring unremitting watchfulness and safeguarding of corporate assets. There must be a concerted effort to eliminate unnecessary vulnerabilities across an enterprise through diligent system hardening to reduce the potential for zero-day exploits.

Comprehensive system hardening leaves slim pickings for malicious actors

Undiscovered vulnerabilities throughout enterprise apps, operating systems, databases and networks create the kind of zero-day exploits that have led to many devastating breaches worldwide. When a business is unaware of a vulnerability, and no patch exists for a quick fix, hackers have free reign to infiltrate and unleash their destructive campaigns. System hardening can decrease security risk by condensing and tightening cybersecurity infrastructure to eliminate potential attack vectors.

So, what is system hardening? It is a process that encompasses the tools, techniques and best practices for decreasing vulnerabilities found within all elements of an enterprise’s IT environment. Restrictive rules developed by IT and security teams remove unnecessary programs, apps, access privileges and permissions that weaken cybersecurity infrastructure. With a methodical approach, security and IT teams audit, identify, close and control any weak points and exploitable vulnerabilities throughout the organization.

System Hardening Best Practices

Adopting a program that follows many of these steps can significantly prevent zero-day threats.

1. Create a system hardening strategy that includes risk assessments and employs a phased approach that prioritizes the big issues.

2. Audit existing systems and technology using pen testing, scanning for vulnerabilities and configuration management. Develop an ongoing auditing cycle.

3. Eliminate unnecessary accounts and privileges and enforce least privileges. It is crucial to remove any orphaned or unused accounts.

4. Adopt an automated patching system to ensure patches are reliably created and activated immediately.

5. Restrict privileged access to systems and accounts with PAM and password management to reduce unnecessary privileges.

6. Block any unnecessary open network ports and encrypt network traffic.

7. Apply OS updates automatically.

Ongoing infrastructure assessments, using the best practices of system hardening will significantly improve security through attack surface reductions, while simplifying transparency.
