Under SI.L2-3.14.2, where must organizations provide malicious code protection?

Organizations must provide malicious code protection at designated locations within their systems to ensure comprehensive security. This requirement focuses on the need to establish specific areas in the infrastructure—such as servers, endpoints, and network devices—where security measures can effectively monitor and combat malicious code threats. By clearly designating these locations, organizations can implement layered defenses that enhance their overall cybersecurity posture.

Addressing only financial transaction locations would limit protection to a narrow scope of the organization's operations, which is inadequate for comprehensive security. Similarly, restricting protection to only mobile devices neglects the broader threats posed to other parts of the organization’s IT environment, such as desktops, servers, and networks. While securing external communications channels is essential, it doesn't cover internal vulnerabilities that malicious code may exploit; therefore, a focused approach on designated locations ensures a more robust and thorough security strategy across the organization.
