2. A security policy must always be a written document. **False**. While it is common for security policies to be documented in written form, they can also exist in verbal or implied formats depending on the organization's practices.
3. Guidelines are the detailed instructions that people must follow to implement the letter-of-the-law intended by the policies. **True**. Guidelines provide specific instructions on how to adhere to the overarching policies effectively.

5. Security policies must be both enforceable and enforced. **True**. For security policies to be effective, they must be capable of being enforced and must be enforced consistently to ensure compliance.
6. Key lengths are measured in terms of the number of bits they contain, which is known as key strength. **True**. Key lengths are a crucial factor in determining the security of encryption systems, with longer key lengths generally being associated with higher levels of security.
