Which of the following is the BEST control to prevent the transfer of files to external parties through instant messaging (IM) applications?
Which of the following is the BEST control to prevent the transfer of files to external parties through instant messaging (IM) applications?
Application level firewalls can be configured to block specific types of traffic, such as file transfers, while allowing other types of traffic. This makes them the best control to prevent the transfer of files to external parties through instant messaging applications. File-level encryption does not prevent the transfer; it only secures the files during transmission. An instant messaging policy is a guideline, not a technical control, and FTP is a protocol for transferring files, not a method to prevent transfers.
I think answer is B because it's asking to prevent the transfer of files so it has to be stopped. Application level firewall should be able to do it.
i also think B could be right answer
answer is B
How A is the correct answer here. By encrypting something doesn't stop it from being transferred.. Who provides these answers??
should be B, A is not preventive measure.
application level firewalls can be configured to block specific types of traffic, such as file transfers, while allowing other types of traffic
Correct answer is C. B is not a solution, app level firewall is not a DLP solution. If IM is allowed in the org, app level firewall wont prevent sharing sensitive files over IM. What you need is a DLP solution, but that is not part of the answers, so Policy is the next best choice.
B is correct. example.. WAF.. deny rule of file
While file-level encryption (option A) can help protect the confidentiality of files during transmission, it does not specifically prevent the transfer of files to external parties through IM applications. Encryption ensures that files are securely transmitted, but it does not control whether files are sent externally.
Not A, encryption won't stop transfer... Not B, App FW will stop the IM app, which is not our goal It is C
