Here are some solutions and best practices to address this challenge:

Addressing the current issue:

    IP-based blocking:
        Implement IP-based blocking within the WAF policy. This approach tracks failed login attempts originating from a specific IP address and blocks them after exceeding a predefined threshold.
        Consider limitations: While IP blocking can be effective, it might cause inconvenience to legitimate users sharing the same IP address.

    Advanced Bot Detection:
        Utilize Sangfor's advanced bot detection capabilities within the WAF. These features can analyze various factors beyond cookies, including:
            User behavior patterns (e.g., rapid login attempts, unusual access times)
            Request headers and origin characteristics
        This multi-layered approach can help identify and block automated bots attempting brute-force attacks.

    Multi-factor Authentication (MFA):
        Enforce MFA as an additional security layer for web-based logins. This requires users to provide a secondary verification code beyond the username and password, significantly increasing the difficulty of unauthorized access through brute-force attempts.

Best practices for brute-force protection:

    Limit login attempts: Set a reasonable limit on the number of consecutive failed login attempts allowed within a specific timeframe.
    Increase lockout duration: Gradually increase the lockout duration for subsequent failed attempts to discourage persistent attacks.
    Captcha implementation: Consider implementing CAPTCHA challenges after a certain number of failed attempts. This adds an extra layer of validation to distinguish between legitimate users and automated scripts.
    Regular security audits: Conduct periodic security audits to identify and address any potential vulnerabilities in your web applications that might be susceptible to brute-force attacks.
