In an increasingly fast-paced tech environment, the attack surface has broadened beyond traditional firewalls and network monitoring to include web applications, which serve as new entry points for unauthorized access. As businesses prioritize agile methodologies like CI/CD, the focus on security can wane, increasing vulnerabilities. The attack surface, defined by known and unknown components, includes intentional and unintentional web application exposure, which can be exploited by attackers. Effective reduction strategies involve keeping an inventory of web applications, identifying technologies in the tech stack, approaching asset discovery like a hacker, integrating security checks into the development lifecycle, maintaining updated software, and addressing even minor vulnerabilities. Organizations are encouraged to adopt a proactive and integrated approach to security by embedding it into development cycles and maintaining awareness, as innovation and business needs necessitate continuous production and code development.
