20+ practice questions focused on Systems and Application Security — one of the most tested topics on the Systems Security Certified Practitioner SSCP exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Systems and Application Security PracticeA security analyst is reviewing security events on a Linux server and needs to ensure that all authentication attempts, including both successful and failed logins, are logged. Which configuration should be used?
Explanation: auditd is the Linux kernel-level audit subsystem that can capture authentication events — including successful and failed logins — via configurable rules (e.g., watching /var/log/secure, /etc/pam.d, or using the 'loginuid' mechanism). It provides comprehensive, tamper-resistant logging that satisfies the requirement to log all authentication attempts.
Which of the following is a primary security concern when using VM snapshots in a virtualized environment?
Explanation: VM snapshots capture the complete state of a virtual machine—including its disk, memory, and configuration—at a specific point in time. If the guest OS inside the snapshot has not been patched since the snapshot was taken, restoring that snapshot reintroduces all the vulnerabilities that were present at capture time, effectively rolling back security updates. This makes unpatched vulnerabilities the primary security concern, since snapshots can silently undo remediation efforts.
A company is deploying a web application and wants to protect against OWASP Top 10 attacks. Which THREE controls should be implemented? (Select THREE.)
Explanation: A Web Application Firewall (WAF) is correct because it inspects HTTP/HTTPS traffic and blocks common OWASP Top 10 attacks such as SQL injection, cross-site scripting (XSS), and command injection at the application layer. Input validation and parameterized queries are correct because they prevent injection flaws (A03:2021-Injection) by ensuring untrusted data is never interpreted as executable SQL or script, which is a core OWASP mitigation. Code signing for application binaries is correct because it ensures integrity and authenticity of deployed code, mitigating OWASP risks like software and data integrity failures (A08:2021) and preventing tampered or malicious binaries from running. Disabling auto-run on user workstations addresses removable-media malware propagation and is not a web application control for OWASP Top 10 web flaws. A host-based IDS on the database server provides detection rather than prevention and does not directly mitigate the OWASP Top 10 web application attack classes.
A security engineer is evaluating cloud security tools. Which TWO of the following are primarily used to protect cloud workloads? (Select two.)
Explanation: Option B, Cloud Workload Protection Platform (CWPP), is correct because CWPPs are specifically designed to secure running workloads such as VMs, containers, and serverless functions, providing runtime protection, vulnerability management, and behavioral monitoring at the workload level. Option C, Web Application Firewall (WAF), is correct because a WAF protects cloud-hosted web applications and APIs by inspecting HTTP/HTTPS traffic and blocking common attacks like SQL injection and cross-site scripting (XSS), directly shielding the application workload from exploitation. Option A, IAM, is not primarily a workload protection tool; it governs authentication, authorization, and access policies for identities and resources rather than defending the workload itself. Option D, CSPM, focuses on identifying misconfigurations and compliance risks in cloud infrastructure and posture, not on actively protecting running workloads. Option E, SIEM, aggregates and correlates log and event data for detection and response, but it is a monitoring and analytics platform rather than a workload protection mechanism.
A security analyst notices that a Linux server has an unusual number of failed login attempts for the root account. To strengthen authentication security while preserving administrative access, which of the following configurations would be most effective?
Explanation: Implementing account lockout via the PAM module pam_tally2 directly addresses the brute-force pattern observed (repeated failed root logins) by locking the account after a defined threshold of failures, while still allowing legitimate administrative access once unlocked. This is the most effective control because it actively throttles and blocks the attack vector rather than merely hardening files or rotating credentials. It preserves root access for authorized admins, satisfying the 'preserving administrative access' requirement.

Practice all Systems and Application Security questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Systems and Application Security. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Systems and Application Security questions on the SSCP frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Systems and Application Security is tested as part of the Systems Security Certified Practitioner SSCP blueprint. Practicing with targeted Systems and Application Security questions ensures you can handle any format or difficulty that appears.
Yes. Courseiva provides free SSCP practice questions across all exam topics and domains. The platform includes topic-based practice, mock exams, missed-question review, bookmarked questions, and readiness tracking — no account required.
Difficulty is subjective, but Systems and Application Security is a high-priority exam concept tested in multiple ways — direct recall, scenario analysis, and command-output interpretation. Consistent practice is the best way to build confidence.
