The attack surface refers to the sum of all possible security exposures that an attacker could use as an entry point to penetrate a system or network, which is constantly growing and changing, making it difficult to manage. The larger the attack surface, the more opportunities an attacker has to find and exploit vulnerabilities. Organizations are becoming increasingly worried about the expanding attack surface and how to safeguard it by systematically mapping their digital assets and running scans to mitigate potential vulnerabilities. Attackers continuously attempt to find a weakness or entry point in one of the many pieces that make up your internet-facing perimeter, which can lead to extracting data. The role of CISOs has become one of the toughest and most demanding in the business world due to the cumbersome nature of the attack surface. Digital assets include everything outside of the firewall, such as websites, code, ports, email servers, and mobile applications, while physical devices like mobiles, desktop systems, or USB ports are also part of the attack surface. Human error is one of the most common causes of data breaches today, with social engineering attacks like phishing being a prevalent example. Attack vectors are individual exposures or vulnerabilities that make up the external attack surface, and identifying them is crucial for securing digital assets. Regularly assessing vulnerabilities, applying security patches, following the principle of least privilege, implementing secure configurations, and educating employees about cybersecurity can help reduce the attack surface. Attack surface management (ASM) tools provide continuous security monitoring and management of your attack surface and the vulnerabilities that contain, transmit, or process your data, enabling organizations to map, track, understand, and analyze their threat landscape.
