Background for this topic.
Authentication confirms the identity of users or systems before granting access to resources, typically using factors like passwords (knowledge), hardware tokens (possession), or biometrics (inherence). It establishes trust boundaries that prevent unauthorized entities from impersonating legitimate users or devices within networks and applications.
Weak authentication enables attackers to perform account takeover, privilege escalation, or lateral movement by exploiting stolen credentials, phishing, or replay attacks. Deploying multi-factor authentication (MFA) with independent factors significantly reduces these risks. Secure credential storage, regular rotation, and monitoring authentication logs for anomalies are critical defenses to detect and block unauthorized access attempts early in the attack chain.
With companies pushing to adopt Zero Trust frameworks, adaptive authentication and access — once languishing — looks finally ready to move out of the doldrums.
A new modular toolkit called 'AlienFox' allows threat actors to scan for misconfigured servers to steal authentication secrets and credentials for cloud-based email services. [...]
Single sign-on (SSO) is an authentication method that allows users to authenticate their identity for multiple applications with just one set of credentials. From a security standpoint, SSO is the gold standard. It ensures access without forcing users to remember multiple passwords and can be further secured with MFA. Furthermore, an estimated 61% of attacks stem from stolen credentials. By
