A downgrade attack is a type of man-in-the-middle attack that forces two hosts to use an older or weaker version of the TLS protocol or its parameters. The attacker does this by replacing or deleting the STARTTLS command or exploiting the compatibility features of the protocol. The purpose of the attack is to create a pathway for enabling a cryptographic attack that would not be possible in case of a connection that is encrypted over the latest version of TLS protocol. The IOC shows that most client connections are renegotiated after establishing the connections, which could indicate that an entity is performing downgrade attacks on path by interfering with the initial handshake and making the client and server agree on a lower version of TLS or a weaker cipher suite.

Law enforcement officials informed an organization that an investigation has begun. Which of the following is the FIRST step the organization should take?

Initiate a legal hold.

Refer to the retention policy

Perform e-discovery.

Review the subpoena

Answer: A

A legal hold is a process by which an organization instructs its employees or other relevant parties to preserve specific data for potential litigation. A legal hold is triggered when litigation is reasonablyanticipated, such as when law enforcement officials inform an organization that an investigation has begun. The first step the organization should take is to initiate a legal hold to ensure that relevant evidence is not deleted, destroyed, or altered. A legal hold also demonstrates the organization’s good faith and compliance with its duty to preserve evidence. Verified References:
