CompTIA Updated CAS-005 Exam Questions and Answers by romie

A crisis management plan defines coordinated communication and response strategies for high-profile incidents that may harm an organization’s public reputation and shareholder confidence. CAS-005 GRC content includes crisis communication planning for regulatory compliance and public relations in the wake of breaches.

A Data Subject Access Request (A) addresses individual data rights, not overall crisis handling.

Business Impact Analysis (B) helps assess potential operational and financial impacts but does not manage public perception during an incident.

Supply chain management (C) is preventative for vendor risks, not responsive to current crises.

Regression testing is a software testingpractice that ensures that recent code changes have not adversely affected existing functionalities. In this scenario, the reintroduction of a previously fixed bug indicates that changes or integrations brought back the old issue. Implementing comprehensive regression testing would help detect such reintroductions by systematically retesting the existing functionalities whenever changes are made to the codebase. This practice is crucial in maintaining the integrity of the application, especially in complexsystems where multiple components interact.​

A risk register is atool commonly used in risk management to document all identified risks, their assessment in terms of likelihood and impact, and the actions steps to manage them. By adding the newly identified risks to the risk register and assigning an owner and severity, the organization ensures that each risk is visible to stakeholders and has a designated individual responsible for its management. This aligns with the company's requirements for transparency and accountability in risk management.​

The vulnerability lies in line [10], where the function strcpy(transmit, input) is used. The strcpy function does not perform boundary checking when copying strings. Since input is defined with a size of 256 characters and transmit only has 20 characters allocated, the strcpy operation will cause a buffer overflow when the contents of input exceed the allocated size of transmit. This creates a significant security vulnerability, as attackers can overwrite adjacent memory, potentially injecting malicious code or altering program execution.

Lines [02], [04], [07], and [08] are not inherently vulnerable by themselves. Line [04] defines the oversized input, but the vulnerability only materializes when combined with the unsafe copy in line [10]. Secure coding practices recommend using safer alternatives like strncpy, which includes a length parameter, or implementing runtime checks to ensure the destination buffer size is not exceeded.

Thus, the vulnerable line that must be changed is line [10], where strcpy is used.
