To ensure device security on the network while adhering to industry best practices, the technician should:

Automate the patching process: This ensures that all devices receive the latest security updates in a timely manner without manual intervention, reducing the risk of vulnerabilities.

Monitor the firewall configuration: Important for network security but does not directly ensure all devices are patched.

Implement access control lists: Controls access to resources but does not ensure devices are patched.

Document all changes: Important for change management but does not directly impact the patching process.

Disk encryption is the best method for securing a workstation used in financial transactions, such as point-of-sale systems. It ensures that if the workstation is stolen, all data on the disk is encrypted and cannot be accessed without proper credentials. File encryption (B) only encrypts individual files, and USB drive encryption (C) only applies to removable storage. Data-in-transit encryption (A) is not relevant for physical security.

When an organization refuses to pay the ransom for a decryption key after a ransomware attack, and all traces of the infection have been removed, the next critical step is:

Restore critical data from backup: This is the most effective way to recover from a ransomware attack without paying the ransom. Assuming the organization has good backup practices, the backups should be free from infection and can be restored to get the systems operational again.

Scan all of the infected files with up-to-date, anti-malware cleaning software: This step is important during the infection removal process but does not address restoring the encrypted files.

Fully patch the server operating systems hosting the fileshares: While this is necessary to prevent future attacks, it does not recover the encrypted files.

Change the files to be read-only: This will not help recover the encrypted data.

Authenticator applications are designed to enhance security by generating temporary, time-sensitive passcodes used in two-factor authentication (2FA) processes. These passcodes are used in conjunction with traditional credentials (like usernames and passwords) to grant access to systems or applications. This extra layer of security ensures that even if primary login credentials are compromised, unauthorized access is still prevented without the dynamically generated code from the authenticator app.
