 The Encrypting File System (EFS) is a feature of the NTFS file system that provides encryption at the file system level. It is designed to work specifically with NTFS and does not support the FAT file system. When files encrypted with EFS are copied or backed up to a volume that uses the FAT file system, the encryption is lost because FAT does not support EFS encryption. This is why David found that the backup files were not encrypted after transferring them to a system that supports the FAT file system.

References: The explanation is based on the operational characteristics of EFS and its compatibility with different file systems as described in the Certified Network Defender (CND) course materials and further supported by information from reliable sources on EFS and file system encryption1234.

Purging is a data destruction technique designed to protect the sensitivity of information against laboratory attacks. In such attacks, unauthorized individuals may use advanced signal processing recovery tools to recover previously stored information. Purging involves removing the stored data in a way that it cannot be reconstructed by any means, including laboratory techniques. This process often includes degaussing, which demagnetizes the magnetic field of storage media, thereby making data recovery virtually impossible.

References: The information provided aligns with the Certified Network Defender (CND) course’s objectives regarding data destruction and protection against laboratory attacks. For more detailed information, please refer to the official CND study guide and documents.

The last step Malone should list in his incident handling plan is ‘A follow-up’. This step is crucial as it involves analyzing the incident to understand how it occurred and what can be done to prevent similar incidents in the future. It often includes a review of the effectiveness of the response, identification of lessons learned, updating policies and procedures accordingly, and conducting training sessions if necessary. This step ensures that the organization improves its security posture and is better prepared for future incidents.

References: The follow-up step is aligned with the incident response life cycle which includes preparation, identification, containment, eradication, recovery, and then follow-up as the final phase. This is consistent with the best practices in incident response and is covered in the Certified Network Defender (CND) curriculum as well as in the NIST guidelines on incident response1.
