The CompTIA Cybersecurity Analyst+ (CySA+) is the premier certification for intermediate-level cybersecurity professionals responsible for continuous security monitoring, detection, and response. Launched in June 2023 as version 3, this professional-level certification validates expertise in security operations, vulnerability management, incident response, and threat analysis through real-world scenarios and performance-based assessments. The certification emphasizes the critical technical and communication skills necessary for security analysts, SOC (Security Operations Center) analysts, and incident responders to effectively detect, analyze, prioritize, and communicate about cybersecurity threats across enterprise networks and security infrastructure.
The CySA+ certification is designed for intermediate to advanced IT professionals with hands-on cybersecurity experience who are transitioning into or advancing within security operations roles. The target audience includes incident response analysts, SOC analysts, threat intelligence specialists, security engineers, and security operations managers. Candidates should have a minimum of 4 years of hands-on information security or cybersecurity job role experience, preferably with exposure to incident response, threat detection, or security monitoring. This certification is ideal for professionals seeking to validate their expertise in threat detection and incident response or those pursuing career advancement from entry-level security positions (such as Security+ certified professionals) into specialized analyst and operational security roles.
CompTIA recommends candidates hold CompTIA Network+, Security+, or equivalent knowledge before pursuing CySA+. The primary prerequisite is a minimum of 4 years of hands-on, direct experience in information security or cybersecurity roles, specifically as an incident response analyst, security operations center (SOC) analyst, or equivalent position involving continuous security monitoring and threat detection. While formal certification prerequisites are not strictly enforced, CompTIA strongly advises that candidates possess practical experience with security tools, vulnerability assessment methodologies, incident response procedures, and security operations processes before attempting the examination. Candidates should also have foundational knowledge of network architecture, operating systems, and basic security principles.
The CySA+ (CS0-003) exam lasts 165 minutes and contains a maximum of 85 questions consisting of a mix of multiple-choice and performance-based questions (PBQs). The exam uses a scaled scoring system ranging from 100 to 900, with a passing score of 750. Performance-based questions simulate real-world security scenarios requiring hands-on analysis using tools such as Splunk, Wireshark, and Nessus to investigate malicious activity, assess vulnerabilities, and respond to security incidents. The exam is delivered via Pearson VUE testing centers (in-person) and may also be available through remote proctoring options. The version 3 (CS0-003) launched on June 6, 2023, with a typical retirement date three years after launch.
The CySA+ certification significantly enhances career prospects in the cybersecurity field, with certified professionals commanding average salaries of $106,490 in the U.S., with typical ranges between $85,000 and $115,000 depending on experience level, location, and employer size. Entry-level CySA+ positions start around $65,000, while experienced professionals frequently exceed $110,000 annually, with many analysts reporting salary increases of $10,000-$20,000 immediately after certification. The certification qualifies candidates for specialized, in-demand roles including Security Analyst ($80,000-$100,000), SOC Analyst ($90,000-$110,000), Threat Intelligence Analyst, and Incident Responder positions that exist across virtually every industry. CySA+ is DoD (Department of Defense) approved and recognized by major corporations, government agencies, and critical infrastructure organizations as proof of practical threat detection and incident response competency. The job market for information security analysts is expanding rapidly (projected 33% growth over ten years), and CySA+ holders' expertise in threat detection, vulnerability management, and incident response directly aligns with urgent organizational security needs.
5 sample questions with correct answers and explanations. Start a practice session to test yourself across all 700 questions.
1. Contoso's vulnerability management team is prioritizing remediation efforts. They have four vulnerabilities to address but limited resources to patch only two this week. Which TWO vulnerabilities should be remediated FIRST based on risk-based prioritization best practices? (Select two!)
Multiple correct answersExplanation
CVE-2024-2222 should be prioritized because it is listed on the CISA Known Exploited Vulnerabilities catalog, meaning it has confirmed active exploitation in the wild. CISA KEV inclusion represents the highest urgency regardless of CVSS score, and the vulnerability affects an internet-facing production server. CVE-2024-3333 should be prioritized because despite its moderate CVSS score of 6.8, it has an extremely high EPSS score of 0.85, meaning there is an 85% probability of exploitation within the next 30 days, and it affects a payment-processing server where exploitation would have severe business impact. CVE-2024-1111 has a high CVSS score but extremely low exploitation probability and affects a non-critical development server. CVE-2024-4444 has the highest CVSS score but near-zero exploitation probability and affects only a documentation workstation. CVE-2024-5555 has low scores across all metrics and is in an isolated environment.
2. Tailspin Toys' security operations team needs to implement vendor-agnostic detection rules that can be written once and automatically converted to work across their heterogeneous SIEM environment, which includes both Splunk and Microsoft Sentinel. Which detection rule format should the team adopt? (Select one!)
Explanation
Sigma rules are YAML-based, vendor-agnostic detection rules designed specifically for SIEM platforms. They can be written once and converted to platform-specific query languages such as SPL for Splunk or KQL for Microsoft Sentinel using tools like pySigma or sigma-cli. This write-once-deploy-everywhere approach is ideal for heterogeneous SIEM environments. YARA rules are used for malware identification and classification based on binary patterns, not SIEM detection rules. Snort rules are specific to the Snort intrusion detection system for network traffic analysis, not SIEM log correlation. Suricata rules are network-based IDS/IPS signatures compatible with Snort syntax but focused on network traffic inspection rather than SIEM log analysis.
3. Fabrikam's security team is conducting a vulnerability assessment of their infrastructure. They perform a non-credentialed Nessus scan of a Windows Server 2019 system and find 18 vulnerabilities. A credentialed scan of the same system is then performed. What is the MOST likely outcome of the credentialed scan compared to the non-credentialed scan? (Select one!)
Explanation
Credentialed scans dramatically increase vulnerability detection because the scanner can log into the target system and inspect internal configurations, installed software versions, registry settings, missing patches, and file permissions. In documented testing, non-credentialed scans of a partially patched Windows system found approximately 20 vulnerabilities while credentialed scans of the same system found over 215 vulnerabilities — more than a tenfold increase. Non-credentialed scans are limited to external banner grabbing, port enumeration, and protocol-level checks, missing the vast majority of local vulnerabilities. The two scan types use different assessment approaches, not identical plugins, and credentialed scans consistently find more vulnerabilities, not fewer.
4. Contoso's SOC analyst is reviewing Windows Security Event Logs after receiving an alert about potential lateral movement. The analyst observes multiple Event ID 4624 entries with Logon Type 3 originating from a single workstation targeting several servers within 10 minutes, followed by Event ID 4672 on each destination server. Which attack technique is MOST likely occurring? (Select one!)
Explanation
The combination of Event ID 4624 with Logon Type 3 (network logon) targeting multiple servers in rapid succession, followed by Event ID 4672 (special privileges assigned) on each destination, is a classic indicator of pass-the-hash lateral movement. The attacker uses stolen NTLM hashes to authenticate to remote systems via SMB without knowing the plaintext password. Brute force attacks would generate numerous Event ID 4625 (failed logon) entries before a successful logon. Kerberoasting involves requesting Kerberos service tickets (Event ID 4769) and cracking them offline, not direct authentication to multiple servers. Golden Ticket attacks forge Kerberos TGTs and would generate anomalous Event ID 4768 entries with unusual encryption types rather than standard NTLM-based network logons.
5. Litware's security operations team is building an executive dashboard for quarterly board presentations. The CISO wants metrics that communicate security posture effectively to non-technical board members. Which combination of dashboard design principles should the team follow? (Select two!)
Multiple correct answersExplanation
Limiting dashboards to 5-8 key metrics with traffic light color coding (red/yellow/green) enables non-technical board members to instantly assess security posture without being overwhelmed by data. This follows the principle that executive dashboards should communicate risk status clearly and concisely. Including trend lines for key metrics like Mean Time to Detect, Mean Time to Respond, and vulnerability counts over time allows board members to see whether the security program is improving or degrading, which is more valuable than point-in-time snapshots. Including 15-20 detailed metrics overwhelms non-technical audiences and violates the principle of limiting data points per view. Displaying raw CVSS vector strings and SPL queries is appropriate for SOC analyst dashboards but completely inappropriate for board-level presentations where business-oriented language is required. Presenting all metrics in the same format ignores the fundamental principle that role-based views are essential — executive dashboards serve a fundamentally different purpose than SOC analyst dashboards.
