Why are authorization lists so prone to unauthorized change that they have to be encrypted and protected against unauthorized access? What type of damage may be done if these files were updated in an unanticipated or unplanned way?

To what end does hashing passwords in a separate file and encrypting the password file serve as security measures?

What is the role of a TPM when implementing whole disk encryption?

Authorization lists should be encrypted and secured since they are so vulnerable to manipulation. Imagine if someone messed with these files without meaning to.

The number of encryption operations required to transmit a big file is comparable for block chaining and feedback techniques.How much more effective is one alternative compared to the other?

Why must authorization lists be encrypted? What happens if these files are accidentally modified?

Why is data encryption so important?

The tripwire program is an example of a host-based intrusion detection system. This tool examines files and folders on the system and notifies the administrator of any changes. It employs a protected database of cryptographic checksums for each file reviewed and compares them as they are scanned. It must be set with a list of files and directories to check and changes allowed. It can allow adding new entries to log files but not changing old ones. What are the benefits and drawbacks of employing such a tool? Consider the issue of selecting which files should be checked and which should be reviewed rarely. Consider the time spent configuring the application and monitoring the results.

In what ways are password protection and other forms of access control useful for enforcing rules?
