What is an acceptable action for ensuring the integrity of classified information?

Using encryption when transmitting classified information is an essential practice for ensuring the integrity and security of that information. Encryption protects data by converting it into a code, making it unreadable to unauthorized users. This is vital in maintaining confidentiality, preventing interception or disclosure during transmission, and ensuring that the information remains intact and unaltered from its original form.

In contrast, making copies of classified documents for convenience can lead to unauthorized access or mishandling of sensitive information, which compromises the integrity of the information. Sharing classified information in casual conversations poses significant risks of inadvertent disclosure, undermining both the security and integrity of the data. Additionally, using unapproved devices for accessing classified data can create vulnerabilities, as these devices may not have the necessary security measures in place to protect classified information. Therefore, the adoption of encryption is a key measure in safeguarding classified information integrity.
