Behavioural Blocking with 3rd-Party AVs

Correct Answer: A.

Option A is correct.

EDR with Block mode allows you for blocking even when another AV is in use.

Option B, C, D are incorrect.

Feedback-loop and Client behavior blocking is used with Defender AV.

Reference:

Behavioral blocking is a security mechanism that identifies and blocks potentially malicious behavior based on pre-defined rules or heuristics. It is an important component of a security operations center (SOC) as it helps detect and prevent security incidents in real-time.

Third-party antivirus (AV) solutions can also provide behavioral blocking capabilities that complement traditional signature-based detection. These capabilities may include:

A. EDR with block mode: Endpoint Detection and Response (EDR) is a security technology that provides real-time visibility into endpoint activities, detects suspicious behavior, and responds to threats. EDR solutions with block mode can automatically quarantine or block malicious activity detected on an endpoint.

B. Feedback-loop blocking: Feedback-loop blocking is a type of behavioral blocking that uses machine learning algorithms to continuously learn and improve the accuracy of blocking decisions. When a potential threat is detected, the feedback-loop model analyzes the behavior and decides whether to allow or block it. If the behavior is determined to be malicious, the feedback-loop model adds this information to its database, improving its ability to detect similar threats in the future.

C. Client behavior blocking: Client behavior blocking is a type of behavioral blocking that identifies and blocks specific types of client-side attacks, such as phishing, drive-by downloads, or malvertising. This technique is based on behavioral analysis of the network traffic generated by the client application.

D. Malicious behavior blocking: Malicious behavior blocking is a type of behavioral blocking that detects and blocks known malicious activity, such as command and control (C2) communications, fileless malware, or ransomware. This technique is based on a set of pre-defined rules or heuristics that describe the behavior of known malware families.

In conclusion, all the options provided in the question are valid types of behavioral blocking that can be utilized with third-party AV solutions. The choice of which type of behavioral blocking to use will depend on the organization's specific security needs, risk profile, and budget.
