Why Your Security Maturity Score Is Lying to You

Login endpoints can leak sensitive information through response times, even when returning generic invalid credentials messages. If a system validates emails before passwords, the time difference reveals whether an account exists. Simultaneously, security maturity scores, such as those from NIST Cybersecurity Framework or ISO 27001, may provide misleading representations of actual security postures during board meetings. These issues highlight critical gaps between perceived security compliance and the reality of technical vulnerabilities in modern systems.
