Know all your network’s weakest points to fortify your cyber defense. Identifying all your subdomains and making sure these are sufficiently protected at all times is essential to optimize your cybersecurity posture.
Finding subdomains is an important step in the information gathering phase of a penetration test. Ensure that none of your unused or forgotten subdomains are left dangling, making them easy targets for attackers to gain unauthorized entry into your network.
Only by examining even the subdomains of suspicious sites can you truly stay protected from all kinds of possible harm. Include every malicious subdomain (even those not identified as indicators of compromise [IoCs]) in your blacklists for greater security.
Digging as deep as possible into your web infrastructure lets you evaluate all connected systems for vulnerabilities. Make a quick self-assessment to uncover all potential weak points, outdated software, or misconfigurations.
