    Study Notes

    Conventional Authentication Model Weaknesses

    • Conventional authentication model relies solely on verifying user credentials, leaving it vulnerable to password guessing or login bypass attacks.

    Defensive and Offensive Measures

    • Defensive and offensive measures are implemented to mitigate potential attacks.
    • These measures focus on handling errors, maintaining audit logs, alerting administrators, and reacting to attacks.

    Handling Errors

    • Handling unexpected errors gracefully is crucial, as malicious users may exploit unanticipated errors.

    Reacting to Attacks

    • Attacks often involve attackers probing applications for vulnerabilities, submitting numerous requests with crafted input.
    • Administrative functionality might have weaker security testing, as users may be deemed trustworthy, or testers given low-privilege access.
