CompTIA Updated CAS-004 Exam Questions and Answers by ruairi

WPA3-Personal is a simple, secure solution for a small business with a single access point. It uses a new security protocol called Simultaneous Authentication of Equals (SAE), which replaces the Pre-Shared Key (PSK) exchange with a more secure way to do initial key exchange. SAE also provides forward secrecy, which means that even if the password is compromised, the attacker cannot decrypt past or future data. WPA3-Personal also uses AES-128 in CCM mode as the minimum encryption algorithm, which is resistant to offline password attacks. WPA3-Personal requires low administrative overhead and supports a single SSID with no guest access. Verified References:

Rules of engagement are legal documents that should be signed by all parties involved in an assessment to ensure they understand their roles and responsibilities. Rules of engagement define the scope, objectives, methods, deliverables, limitations, and expectations of an assessment project. They also specify the legal and ethical boundaries, communication channels, escalation procedures, and reporting formats for the assessment. Rules of engagement help to avoid misunderstandings, conflicts, or liabilities during or after an assessment.

 Disabling file exchange can help to minimize data leakage by preventing users from sharing sensitive documents or data through the videoconferencing platform. Enabling watermarking can help to maintain customer trust and ensure non-repudiation by adding a visible or invisible mark to the video stream that identifies the source or owner of the content. Enabling the user authentication requirement can help to secure the videoconferencing sessions by verifying the identity of the participants and preventing unauthorized access. Verified References:

The three metric groups that are needed to calculate CVSS scores are Base, Temporal, and Environmental. The Base metrics represent the intrinsic characteristics of a vulnerability that are constant over time and across user environments. The Temporal metrics represent the characteristics of a vulnerability that may change over time but not across user environments. The Environmental metrics represent the characteristics of a vulnerability that are relevant and unique to a particular user’s environment. Verified References:
