CS0-003 Exam Dumps - CompTIA CySA+ Questions and Answers

A Cloud Access Security Broker (CASB) would have reduced the complexity of identity and access management in cloud-based assets. CASBs provide visibility into cloud application usage, data protection, and governance for cloud-based services.

Risk scoringis the best method for prioritizing patching, as it considers factors likeCVSS severity, exploitability, asset criticality, and business impact​.

Option A (Affected hosts)is relevant but does notdetermine prioritywithout a risk assessment.

Option C (Mitigation strategy)is useful but focuses on alternative protections rather than prioritization.

Option D (Annual recurrence)is not a standard method for vulnerability prioritization.

Thus,B is the correct answer, asrisk scores allow organizations to prioritize patching efforts effectively​.

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.

Allowing anonymous read access to /etc/passwdis acriticalvulnerability because it canexpose user account details, aiding attackers inpassword cracking and privilege escalation​.

Option B (Anonymous FTP access)is a risk, but /etc/passwd exposure ismore criticalas it directly affects user authentication.

Option C (Defender updates disabled)isimportant, but it does not present animmediateattack vector like credential exposure.

Option D (less escape exploit)is significant, but it requires user interaction, making itless immediate than a global credential leak.

Thus,A is the correct answer, as it representsan immediate, high-impact security risk​.

The first step in building a disaster recovery plan (DRP) for critical on-prem applications is to determine what is actually “critical” to the business, how long the organization can tolerate those applications being down, and therefore what restoration order (prioritization) is required. That prioritization must come from business/data owners and stakeholders, because they understand operational dependencies, business impact, and acceptable downtime.

This is essentially the start of a Business Impact Analysis (BIA) and related continuity prioritization work, which precedes choices like vendors, contracts, or site geography. You don’t select a DR site/vendor or negotiate agreements until you know which systems must be restored first and what recovery objectives you must meet.

Supporting exact extracts:

The All-in-One CS0-003 guide explains that the foundation is identifying critical systems and determining tolerable outage time (used to prioritize restoration):Exact extract (All-in-One Exam Guide): “The key is to determine which of the organization’s critical systems are needed for survival and then estimate the outage time that can be tolerated by the organization…” It then connects those determinations directly to prioritization:Exact extract (All-in-One Exam Guide): “These estimates will help you determine how to prioritize response team efforts to restore these assets.”

The Secbay Press CS0-003 guide lays out the early BIA/risk identification steps in order, starting with identifying what’s critical before recovery priorities:Exact extract (Secbay Press): “1. Identify critical processes and resources2. Identify outage impacts and estimate downtime3. Identify resource requirements4. Identify recovery priorities”

Why the other options are not the first step:

A / C (vendor selection / vendor agreements): those come after requirements are defined (RTO/MTD, criticality, order of restoration).

D (define geographic area): location considerations are important, but they are driven by requirements and constraints discovered during BIA/continuity prioritization (what needs to be recovered, how fast, and with what dependencies).

Using a vendor-provided API to automate pulling logs in real-time is the best option for improving the efficiency of security operations when the financial application does not allow event logging to send to the corporate SIEM. This approach ensures that logs are consistently and promptly integrated into the security monitoring process without manual intervention, enhancing the overall effectiveness of security operations.

The first step should be to perform a public search for malware reports on taskhw.exe, as this file is suspicious for several reasons: it is located in a non-standard path, it has a high CPU usage, it is signed by an unknown entity, and it is only present on one host. A public search can help to determine if this file is a known malware or a legitimate program. If it is malware, the hunter can then take appropriate actions to remove it and prevent further damage. The other options are either premature or ineffective, as they do not provide enough information to assess the threat level of taskhw.exe. References: Cybersecurity Analyst+ - CompTIA, taskhw.exe Windows process - What is it? - file.net, Taskhostw.exe - What Is Taskhostw.exe & Is It Malware? - MalwareTips Forums

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 next step in the remediation process after applying a software patch is validation. Validation is a process that involves verifying that the patch has been successfully applied, that it has fixed the vulnerability, and that it has not caused any adverse effects on the system or application functionality or performance. Validation can be done using various methods, such as scanning, testing, monitoring, or auditing.
