1. CIA triad: confidentiality, integrity, availability—the core of security goals.

2. Authentication factors: something you know, have, are; MFA combines two or more.

3. Encryption vs. hashing: encryption is reversible with a key; hashing is one-way.

4. Public Key Infrastructure (PKI): certificates, keys, trust chains for secure exchange.

5. Least privilege: give only the access required—nothing more.

6. Network segmentation: isolate critical systems to limit blast radius.

7. Patching cadence: fix known vulnerabilities before they’re weaponized.

8. Logging & monitoring: collect events, detect anomalies, retain for forensics.

9. Risk vs. threat vs. vulnerability: risk = likelihood × impact, threats exploit vulns.

10. Secure defaults: deny-by-default, strong configs, no open ports without purpose.

1. Phishing remains the most common initial access—humans are targets.

2. Ransomware pairs encryption with data theft to increase leverage.

3. Business Email Compromise (BEC) exploits trust and urgency, not malware.

4. Zero-day exploits abuse unknown flaws before a patch exists.

5. Supply-chain attacks compromise vendors to reach many victims at once.

6. DDoS floods apps or networks to knock services offline.

7. Credential stuffing reuses leaked passwords at scale.

8. Insider threats can be malicious or simply careless.

9. Botnets rent out compute power for spam, DDoS, and brute force.

10. Cloud misconfigurations are low-effort, high-impact attacker wins.

1. EDR/XDR: endpoint telemetry + detection to stop lateral movement.

2. SIEM: centralizes logs, correlates events, powers alerting & forensics.

3. SOAR: automates playbooks for faster, consistent incident response.

4. WAF: filters malicious web traffic (SQLi, XSS) at the edge.

5. IDS/IPS: detects and blocks known attack patterns and anomalies.

6. MFA & Passkeys: phishing-resistant user verification.

7. PAM: controls privileged accounts, rotates secrets, just-in-time access.

8. VPN vs. ZTNA: network tunnel vs. identity-driven, app-level access.

9. Backup & immutability: versioned, offline copies enable reliable recovery.

10. Secret managers: vault API keys, certificates, and credentials securely.

1. SQL injection: unsanitized inputs let attackers query or alter databases.

2. XSS: injected scripts hijack sessions or deface pages.

3. CSRF: forged requests exploit user trust and active sessions.

4. SSRF: targets internal services via server-side fetches.

5. RCE: remote code execution from deserialization or unsafe evals.

6. Privilege escalation: misconfigs or bugs expand attacker rights.

7. Default/weak creds: forgotten admin:admin opens the front door.

8. API keys in repos: leaked secrets enable unauthorized access.

9. OAuth misconfig: token scopes/grants too broad, refresh unguarded.

10. MFA fatigue: push bombing tricks users into approving logins.

1. CAPTCHA evolved from distorted text to behavior and risk-based checks.

2. Salting hashes: like adding spice—unique per password prevents rainbow tables.

3. Honeypots lure attackers to study TTPs without risking prod assets.

4. Air gaps help—but “sneakernet” and insiders can still bridge them.

5. Steganography hides messages within images, audio, or video.

6. Quantum computing threatens certain crypto; post-quantum algorithms emerge.

7. Dark web markets mirror real economies—reputation, escrow, service tiers.

8. Bug bounties turn vulnerability discovery into a legitimate career.

9. Side-channel attacks read secrets via power, timing, or cache patterns.

10. Threat intel lifecycle: direction, collection, analysis, dissemination, feedback.

Q: Is antivirus enough?
A: No. Layered defenses (MFA, EDR, patching, backups) are essential.

Q: What is Zero Trust?
A: “Never trust, always verify”—continuous, context-aware access checks.

Q: How often should we patch?
A: Monthly baseline, with expedited cycles for critical issues.

Q: Encryption vs. hashing?
A: Encryption protects data confidentiality; hashing verifies integrity.

Q: Can MFA be bypassed?
A: Yes via phishing and fatigue; use phishing-resistant methods and alerts.

Q: VPN or ZTNA?
A: ZTNA limits access per app and identity—often safer than full network tunnels.

Q: Spotting phishing?
A: Check sender, links, urgency, and requests for credentials or payment.

Q: Backup best practice?
A: 3-2-1 rule: 3 copies, 2 media, 1 offsite/immutable.

Q: Public Wi-Fi safety?
A: Use VPN/ZTNA, avoid sensitive actions, disable auto-join.

Q: After a breach?
A: Isolate, preserve logs, rotate creds, notify, and eradicate root cause.
