The key goal of the containment stage in an incident response process is to limit further damage from occurring. This involves taking immediate steps to isolate the affected systems or network segments to prevent the spread of the incident and mitigate its impact. Containment strategies can be short-term, to quickly stop the incident, or long-term, to prepare for the eradication and recovery phases.

The best security control to implement against sensitive information being disclosed via file sharing services is to improve employee training and awareness. Employee training and awareness can help educate employees on the risks and consequences of using file sharing services for sensitive information, as well as the policies and procedures for handling such information securely and appropriately. Employee training and awareness can also help foster a security culture and encourage employees to report any incidents or violations of information security.

Fuzzing is a testing technique where invalid or random data is inputted into a system to find vulnerabilities, crashes, or unexpected behaviors. It’s commonly used in software security to identify flaws that could lead to security breaches. According to CompTIA’s CySA+ curriculum, fuzzing is a dynamic testing method for exposing application weaknesses. Options like static testing (B) involve analyzing code without execution, while reverse engineering (A) and debugging (D) involve different methodologies for understanding or fixing code, not intentionally stressing it.

The first step that should be performed when establishing a disaster recovery plan is to agree on the goals and objectives of the plan. The goals and objectives of the plan should define what the plan aims to achieve, such as minimizing downtime, restoring critical functions, ensuring data integrity, or meeting compliance requirements. The goals and objectives of the plan should also be aligned with the business needs and priorities of the organization and be measurable and achievable.

The correct answer is B because a legal hold requires the organization to preserve potentially relevant information. The first practical step is to notify the departments, custodians, IT staff, and records personnel who may control or possess relevant emails so they do not delete, alter, or overwrite them.

Exact supporting extract: the Secbay CySA+ guide defines legal hold as a process used to preserve relevant information associated with legal proceedings, investigations, or disputes. It states that once a legal hold is in effect, it is crucial to communicate it to relevant personnel who may have custody or control over the information, including IT staff, records management personnel, and employees with pertinent data.

The Sybex CySA+ Study Guide also states that legal holds require organizations to preserve all potentially relevant data and information related to pending or active litigation. It specifically notes that legal holds may involve data such as logs, email, or transactional information that would otherwise be destroyed under normal retention procedures.

Why the other options are incorrect:

A is incorrect because disclosing the request to unrelated vendors could create confidentiality and legal issues.

C is incorrect because chain of custody is important when evidence is collected and transferred, but the first legal-hold step is preservation notification.

D is incorrect because producing mailbox copies to the attorney is premature. The organization must first preserve the relevant data and follow legal/eDiscovery procedures.

Implementing a central place to manage IT assets is the best solution to decrease the inconsistencies regarding versions and patches in the existing infrastructure. A central place to manage IT assets, such as a configuration management database (CMDB), can help the vulnerability assessment team to have an accurate and up-to-date inventory of all the hardware and software components in the network, as well as their relationships and dependencies. A CMDB can also track the changes and updates made to the IT assets, and provide a single source of truth for the vulnerability assessment team and other teams to compare and verify the versions and patches of the infrastructure12. Implementing credentialed scanning, changing from a passive to an active scanning approach, and performing agentless scanning are all methods to improve the vulnerability scanning process, but they do not address the root cause of the inconsistencies, which is the lack of a central place to manage IT assets3.

Port 3389 is commonly used by Remote Desktop Protocol (RDP), which is a service that allows remote access to a system. A vulnerability on this port could allow an attacker to compromise the web server or use it as a pivot point to access other systems. However, if the firewall blocks this port, the risk of exploitation is reduced.
