Incapsula is a cloud-based application delivery platform that offers a comprehensive security solution, including protection against Distributed Denial of Service (DDoS) attacks. By providing DDoS mitigation services, Incapsula helps protect websites and online services from being overwhelmed by traffic intended to make the resource unavailable to its intended users. The platform filters out malicious traffic and allows legitimate traffic through, thus ensuring that the organization's online resources remain available even under attack.

Disabling security options such as two-factor authentication (2FA) and CAPTCHA is not a countermeasure to eradicate cloud security incidents. In fact, it is contrary to best security practices. 2FA adds an additional layer of security by requiring two forms of verification before granting access to an account or system. CAPTCHA helps prevent automated attacks by ensuring that the entity accessing the service is human. Both are important security measures that protect against unauthorized access and automated attacks, thereby enhancing cloud security.

The ECIH Endpoint Security module stresses that modern endpoint incidents require advanced detection capabilities beyond traditional antivirus or manual inspection. Intellectual property theft often involves stealthy techniques that evade basic controls.

Option C is correct because an Endpoint Detection and Response (EDR) solution provides deep visibility into endpoint behavior, including process execution, memory activity, file changes, and lateral movement. EDR enables analysts to detect, investigate, and validate incidents efficiently across multiple endpoints.

Option B is slow and error-prone. Option A is premature without validation. Option D identifies vulnerabilities, not active compromise.

ECIH highlights EDR as a cornerstone technology for endpoint incident detection and validation, especially in high-value environments such as R&D networks.

This scenario involves a session fixation vulnerability, a well-known web application attack where an attacker forces or predicts a session identifier and then tricks a user into authenticating with that session. According to the ECIH web application security module, proper session management is essential to prevent such attacks.

Option B is correct because rotating or regenerating session tokens immediately after successful authentication ensures that any session identifier known to an attacker becomes invalid. This breaks the attack chain inherent in session fixation attacks. ECIH explicitly identifies session regeneration as a primary mitigation control.

Option A helps against automated abuse but does not address session reuse. Option C strengthens authentication but does not prevent session hijacking. Option D improves confidentiality but does not prevent fixation if the same session ID remains valid.

ECIH stresses that authentication and session management must be treated as distinct security controls. Even strong passwords cannot protect against flawed session handling. Therefore, regenerating session tokens post-login is the correct and most effective remediation.
