Geoblocking is the best mitigation technique for unusual network scanning activity coming from a country that the company does not do business with, as it can prevent any potential attacks or data breaches from that country. Geoblocking is the practice of restricting access to websites or services based on geographic location, usually by blocking IP addresses associated with a certain country or region. Geoblocking can help reduce the overall attack surface and protect against malicious actors who may be trying to exploit vulnerabilities or steal information. The other options are not as effective as geoblocking, as they may not block all the possible sources of the scanning activity, or they may not address the root cause of the problem.

Zero Trust Network Access (ZTNA)simplifies secure remote access to cloud and SaaS applications byenforcing identity-based, least-privilege access policies. It eliminates the need to extend traditional network-based access models to the cloud. ZTNA ensures thateach user is verified continuouslyregardless of their network location, aligning perfectly with complex multi-cloud or SaaS environments.

RADIUS (A)is an older authentication protocol, not ideal for SaaS cloud scale.

SDN (B)controls network flow, not identity management.

SWG (D)is a secure web proxy, not for access control and IAM extension.

The correct answer is A because CVSS scores alone do not fully determine remediation priority. A vulnerability with a slightly lower CVSS score on a mission-critical system may need to be remediated before a higher-scoring vulnerability on a low-value or isolated system. The missing information is the criticality of the affected hosts/assets.

Exact supporting extract: the CySA+ All-in-One guide states that analysts should consider exploitability, whether a vulnerability is weaponized, patch availability, and asset value and criticality when determining remediation priority. It also explains that analysts must consider the impact to business operations when taking an asset offline for remediation.

The Secbay CySA+ guide also explains that vulnerability prioritization should evaluate severity, exploitability, and the criticality of affected systems. It specifically states that organizations should identify and prioritize vulnerabilities based on the criticality of the assets they affect and consider business operations, data sensitivity, and regulatory compliance.

Why the other options are incorrect:

A is correct because host criticality is required to confirm which vulnerability should be remediated first.

B is incorrect because SLAs define remediation timelines after prioritization, but the question asks what information is needed to confirm prioritization.

C is incorrect because KPIs measure program performance; they do not determine which vulnerable host is most critical.

D is incorrect because nothing in the question indicates these are zero-day vulnerabilities or that zero-days were excluded.

Key Performance Indicators (KPIs)track the effectiveness of a security program, providing measurable insights intovulnerability detection, patching efficiency, and risk reduction. This makes KPIs ideal for executive dashboards​.

Option B (MOU - Memorandum of Understanding)refers toagreements between parties, not performance tracking.

Option C (SLO - Service Level Objective)defines operationaltargetsbut is nota tracking metric.

Option D (SLA - Service Level Agreement)defines expectations betweenservice providers and clients, not security metrics.

Thus,A (KPI) is the correct answer, asKPIs provide actionable insights into security effectiveness​.

The best priority based on common attack frameworks for a new program to reduce attack surface risks and threats as part of a zero trust approach is to reduce the administrator and privileged access accounts. Administrator and privileged access accounts are accounts that have elevated permissions or capabilities to perform sensitive or critical tasks on systems or networks, such as installing software, changing configurations, accessing data, or granting access. Reducing the administrator and privileged access accounts can help minimize the attack surface, as it can limit the number of potential targets orentry points for attackers, as well as reduce the impact or damage of an attack if an account is compromised.

The Cyber Kill Chain is a framework that describes the stages of a cyberattack from reconnaissance to actions on objectives. The exploitation stage is where attackers take advantage of the vulnerabilities they have discovered in previous stages to further infiltrate a target’s network and achieve their objectives. In this case, the malicious actor has gained access to an internal network by means of social engineering and does not want to lose access in order to continue the attack. This indicates that the actor is in the exploitation stage of the Cyber Kill Chain. Official References: https://www.lockheedmartin.com/en-us/capabilities/cyber/cyber-kill-chain.html

An API endpoint is a point of entry for a communication between two different SaaS-based security tools. It allows one tool to send requests and receive responses from the other tool using a common interface. An API endpoint can be used to notify the other tool in the event a threat is detected and trigger an appropriate action. SMB share, SMTP notification, and SNMP trap are not suitable for SaaS integration security, as they are either network protocols or email services that do not provide a direct and secure communication between two different SaaS tools.

CVE details and IoCs are information that would most likely be required by the infrastructure team so that vulnerabilities can be remediated quickly. CVE details provide the description, severity, impact, and solution of the vulnerabilities that affect the servers. IoCs are indicators of compromise that help identify and respond to potential threats or attacks on the servers. References: Server and Workstation Patch Management Policy, Section: Policy; Patch Management Policy: Why You Need One in 2024, Section: What is a patch management policy?

A lessons-learned review is a process of evaluating the effectiveness and efficiency of the incident response plan after an incident or an exercise. The purpose of the review is to identify the strengths and weaknesses of the incident response plan, and to update it accordingly to improve the future performance and resilience of the organization. Therefore, the incident response plan should be updated after a lessons-learned review.

The correct answer is C. Legal department.

According to the CompTIA Cybersecurity Analyst (CySA+) certification exam objectives, one of the tasks for a security analyst is to “report and escalate security incidents to appropriate stakeholders and authorities” 1. This includes reporting any inappropriate use of resources, such as installing cryptominers on workstations, which may violate the company’s policies and cause financial and reputational damage. The legal department is the most appropriate group to escalate this issue to first, as they can advise on the legal implications and actions that can be taken against the employee. The legal department can also coordinate with other groups, such as law enforcement, help desk, or board members, as needed. The other options are not the best choices to escalate the issue to first, as they may not have the authority or expertise to handle the situation properly.
