Show Suggested Answer Hide Answer
Suggested Answer: A

chmod is a Linux command that can be used to change or modify the permissions of files and directories. The /etc/shadow file is a system file that stores the encrypted passwords of user accounts in Linux. The /etc/shadow file should have restricted permissions to prevent unauthorized access or modification of the passwords. The recommended permissions for the /etc/shadow file are read/write for root user only (600). If the systems administrator observes that the /etc/shadow file has permissions beyond the baseline recommendation, they can use the chmod command to resolve this issue by setting the appropriate permissions for the file. For example, chmod 600 /etc/shadow would set the permissions of the /etc/shadow file to read/write for root user only.181920Reference:CompTIA Security+ SY0-601 Certification Study Guide, Chapter 9: Implementing Identity and Access Management Controls, page 404;chmod - Wikipedia;Linux /etc/shadow file - nixCraft;How to Change File Permissions in Linux - Linuxize

I don't think grep is the best option in this case, we should stick to using chmod to directly change the permissions

But wouldn't using command B) grep help us identify any specific lines with incorrect permissions in the file?

That makes sense, 'chmod' is the right choice for modifying file permissions.
