Order of volatility is a procedure that a computer forensics examiner must follow during evidence collection. It refers to the order in which digital evidence is collected, starting with the most volatile and moving to the least volatile. Volatile data is data that is not permanent and is easily lost, such as data in memory when you turn off a computer. The security analyst should have followed the order of volatility to preserve the most fragile evidence first, such as the malicious script running as a background process, before turning off the infected machine.

The tools that can be used to provide key information in the risk register are SCAP scanner and vulnerability scanner. SCAP stands for Security Content Automation Protocol, which is a set of standards and specifications for automating the management of security configuration, vulnerability assessment, and compliance evaluation. SCAP scanner is a tool that can scan systems and networks for security issues based on SCAP content. Vulnerability scanner is a tool that can scan systems and networks for known vulnerabilities and weaknesses. These tools canhelp the security analyst identify and prioritize the risks associated with the systems and networks, as well as provide possible remediation actions. Verified References:

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:

Configuring user settings in Group Policy is the best way for an administrator to implement the decision to restrict PowerShell access to only administrators. Group Policy is a feature of Windows that allows administrators to manage and enforce settings for users and computers in a domain. By using Group Policy, an administrator can create a policy that blocks or disables PowerShell for all users except for a particular group, such as administrators. This policy can be applied to all computers in the domain or to specific organizational units. This method is more effective and manageable than uninstalling PowerShell, monitoring event logs, providing user education, or blocking PowerShell via HIDS. Verified References:
