What is the recommended first step for mitigating the threat of malicious code on Removable Media?

The recommended first step for mitigating the threat of malicious code on Removable Media is to use methods to detect malicious code. This approach is fundamental because identifying and detecting potential threats is crucial before any protective measures can be effectively put in place. By employing detection methods, organizations can assess the integrity of the files and programs on removable media, allowing them to take appropriate actions, such as quarantining or removing harmful content before it can propagate throughout their systems.

While antivirus software is a common tool for dealing with malicious code, it operates under the assumption that such code has already been introduced into the environment. Detection methods can be proactive, scanning removable media before it is connected to any systems, thereby preventing possible infection lanes. Additionally, detection methods can provide insights into the nature of any threats, which can inform subsequent response strategies.

Implementing full-disk encryption, while a useful security measure for protecting sensitive information, does not directly address the issue of malicious code. Similarly, limiting access to removable media is a good practice to control who can introduce potentially harmful content, yet it does not provide a method for detecting existing threats. Therefore, focusing on detection methods is essential for the initial mitigation of malicious code threats on removable media.
