The Zero-Day Scramble is Avoidable: A Guide to Attack Surface Reduction

Exposure to internet-facing vulnerabilities is a significant concern for security teams, as it can lead to zero-day exploitation before patches are available. The time-to-exploit is decreasing, making it crucial to manage attack surfaces effectively. Many teams underestimate their exposure, leaving them vulnerable to attacks. Reducing the attack surface can be achieved through deliberate management, which involves identifying and mitigating potential vulnerabilities. This approach can help teams stay ahead of emerging threats, rather than constantly reacting to new vulnerabilities. By minimizing exposure, teams can reduce the risk of zero-day exploitation, which occurs when a vulnerability is exploited before a patch is released¹. This proactive strategy is essential for defenders to stay ahead of attackers, as zero-day exploitation can have severe consequences. So what matters to practitioners is that reducing their attack surface can significantly lower their risk of being compromised by zero-day threats.
