Q: What is the CIA triad?
A: Confidentiality (only authorized access), Integrity (data is accurate/unmodified), Availability (systems accessible when needed).
Q: What is Zero Trust?
A: Security model: never trust, always verify. Every access request authenticated/authorized regardless of location. Microsegmentation.
Q: What is the difference between symmetric and asymmetric encryption?
A: Symmetric: one shared key (fast, AES). Asymmetric: public/private key pair (slower, RSA/ECC). Asymmetric often used to exchange symmetric keys.
Q: What is a SIEM?
A: Security Information and Event Management — collects, correlates, and analyzes logs from multiple sources for threat detection.
Q: What is the incident response process?
A: Preparation → Detection/Analysis → Containment → Eradication → Recovery → Lessons Learned.
Q: What is SQL injection?
A: Inserting malicious SQL into input fields to manipulate database queries. Mitigated by parameterized queries/prepared statements.
Q: What is MFA?
A: Multi-Factor Authentication — requires 2+ different factor types: something you know, have, are, or somewhere you are.
Q: What is RBAC?
A: Role-Based Access Control — permissions assigned to roles, users assigned to roles. Simplifies access management.
Q: What is a certificate chain of trust?
A: Root CA → Intermediate CA → End-entity certificate. Browser trusts root CAs in its trust store.
Q: What is the difference between IDS and IPS?
A: IDS: detects and alerts (passive). IPS: detects and blocks (inline, active prevention).
CompTIA Flashcard Study Technique
CompTIA exams cover broad domains with hundreds of concepts. Use these flashcards in short, focused sessions of 15–20 minutes rather than marathon study sessions. Group cards by domain and track which domains have the lowest recall rates — allocate extra study time to those areas. CompTIA exams weight domains differently, so match your flashcard focus to the domain percentages listed in the exam objectives.
