Which protective measure should be implemented to guard against malware that spreads unnoticed through network shares?

• A. Install a definition-based antivirus.
• B. Implement an IDS/IPS.
• C. Implement a heuristic behavior-detection solution.
• D. Implement CASB to protect network shares.

Answer: (C)

Implementing a heuristic behavior-detection solution is a proactive approach to guarding against malware that spreads unnoticed through network shares. Heuristic detection methods analyze software behavior and characteristics to identify potential threats even if those specific threats have not yet been officially recognized by antivirus databases. This is particularly important for detecting new or variant strains of malware that are designed to bypass traditional signature-based systems. Unlike definition-based antivirus solutions, which rely on known malware signatures, heuristic detection can flag abnormal behavior associated with malware attempts, such as unusual access patterns to network shares or unauthorized file modifications. This allows for a quicker response to potential threats, as it does not depend solely on prior knowledge of malware instances. Other strategies, such as employing an IDS/IPS, could provide network-level security but may not be as effective in detecting and responding to the subtle behaviors of malware spread through network shares. Similarly, while a definition-based antivirus system offers a level of protection, it can be inadequate against zero-day threats or file-less attacks that do not match any known signatures. Implementing a Cloud Access Security Broker (CASB) primarily focuses on managing cloud application data security rather than specifically monitoring internal network shares for malware behavior. Thus, the best choice for this particular scenario is to implement a heuristic behavior-d
