Certified Incident Handler (CIH) Practice Ecam

Which practice is essential for an incident responder to eradicate mobile-based security incidents?

1. Delete temporary files and clear the recycle bin

2. Disable automatic updates

3. Use only cloud storage for files

4. Ignore system notifications

The correct answer is: Delete temporary files and clear the recycle bin

The practice of deleting temporary files and clearing the recycle bin is essential for an incident responder to eradicate mobile-based security incidents. During an incident response, it is crucial to remove any remnants of malicious files or applications that may have been downloaded or executed on a mobile device. Temporary files can often harbor traces of malware, user data, or evidence of the incident that, if not cleaned up, could potentially be exploited by attackers or used to re-infect the device. By clearing these files, the incident responder not only ensures that sensitive information is not inadvertently left behind but also helps to eliminate any artifacts that may aid in the resurgence of the security incident. This action is part of a broader strategy of thorough cleansing and remediation that is vital in maintaining the integrity and security of mobile devices in the aftermath of a security breach. The other practices, such as disabling automatic updates, using only cloud storage, or ignoring system notifications, do not contribute to effectively resolving or eradicating mobile-based security incidents. In fact, some might pose further risks rather than addressing the issues at hand.
