To identify existing vulnerabilities in the web application, the best options are to contract a penetration test and create a bug bounty program. A penetration test simulates attacks against the application to uncover security flaws proactively. A bug bounty program incentivizes external security researchers to find and report vulnerabilities, expanding the testing scope without overburdening internal resources. According to CompTIA CySA+, both methods are highly effective in identifying vulnerabilities from an external perspective, particularly when internal resources are limited. Options like a WAF (A) focus more on prevention than detection, while threat modeling (F) and tabletop exercises (D) are generally proactive measures not focused on active flaw identification.

During an incident, the legal team plays a crucial role in handling regulatory compliance and reviewing legal implications, such as contractual obligations and reporting requirements. Advising on regulatory reporting (Option C) ensures the organization meets legal mandates, while reviewing contracts (Option B) can address new or emergency services needed during the incident. According to CompTIA CySA+ and Security+ guidelines, these legal responsibilities are vital for compliance and risk management. Options related to staffing, damage assessments, and clearances typically fall under operational or HR responsibilities rather than legal purview.

Digital signatures ensure the integrity and non-repudiation of emails. Integrity ensures that the message has not been altered in transit, as the digital signature would be invalidated if the content were tampered with. Non-repudiation ensures that the sender cannot deny having sent the email, as the digital signature is unique to their identity. These principles are crucial for legal validity, as recommended by CompTIA Security+ standards. Confidentiality (A) and privacy (C) relate to encryption, while authorization (F) and anonymity (D) are unrelated to the primary purpose of digital signatures in this context.

The vulnerability with the highest CVSS score and an active exploit is Microsoft CVE-2021-34527 (PrintNightmare). Although only present on two instances, its high severity (8.4) and exploitable nature make it a priority. PrintNightmare is a well-known remote code execution vulnerability, which can be a critical risk. According to CompTIA CySA+ and vulnerability management practices, prioritizing based on severity and exploitability is essential, even over the number of instances. Other vulnerabilities listed are less severe or lack active exploitation.

Timeline analysis in digital forensics involves creating a chronological sequence of events based on system logs, file changes, and other forensic data. This process often uses graphical representations to illustrate and analyze how an incident unfolded over time, making it easier to identify key events and potential indicators of compromise. This approach is highlighted in CompTIA Cybersecurity Analyst (CySA+) practices as crucial for understanding the scope and sequence of a security incident. The other options do not involve chronological or graphical analysis to the extent that timeline analysis does.

Documenting the process in a step-by-step format on the team wiki ensures the junior analyst has a clear, repeatable reference. This approach also supports consistency and accuracy, and the documentation can be updated or referenced by other team members as needed. CompTIA emphasizes the importance of procedural documentation in both CySA+ and Security+ for ensuring team members have reliable resources for task execution, which aids in knowledge retention and standardized practices across the team.

Fuzzing is a testing technique where invalid or random data is inputted into a system to find vulnerabilities, crashes, or unexpected behaviors. It's commonly used in software security to identify flaws that could lead to security breaches. According to CompTIA's CySA+ curriculum, fuzzing is a dynamic testing method for exposing application weaknesses. Options like static testing (B) involve analyzing code without execution, while reverse engineering (A) and debugging (D) involve different methodologies for understanding or fixing code, not intentionally stressing it.

The legal team plays a crucial role in managing the legal and compliance aspects of incident response. They review and approve contracts (B) for emergency services, like incident response firms, and provide guidance on regulatory reporting (C), ensuring the organization meets compliance requirements. According to CompTIA Security+ guidelines, legal teams focus on regulatory and contractual matters rather than operational aspects like staffing (A) or security procedures (D).

A Secure Software Development Life Cycle (SDLC) integrates security measures at each stage of development to reduce vulnerabilities and improve the overall security of the software. This is essential for minimizing risks related to software usage and ensuring compliance with regulatory requirements, which is particularly important for organizations handling sensitive data. As per CompTIA standards, a Secure SDLC helps prevent security breaches and protects both the organization and its users from potential harm. Options A, C, and D do not accurately describe the primary goals of a Secure SDLC, which primarily centers on risk reduction and regulatory compliance.
