Cheat Sheet
- Stateful Inspection Firewalls -
During your CompTIA Security+ SY0-501 practice test, you may encounter questions like "which of the following best describes a stateful inspection." It monitors active connections, tracking session state, source/destination IPs, and ports per NIST SP 800-41. Mnemonic: "Stateful = Smart" helps you recall dynamic packet filtering that adapts to ongoing sessions.
- Securing Network Devices -
If you're tackling the network device security quiz section of a CompTIA Security+ SY0-501 practice test, remember to disable unused ports, enforce SSH over Telnet, and apply firmware patches following CIS Benchmarks. Implement strong multi-factor authentication for console and remote access and maintain configuration baselines per NIST SP 800-53. Tip: "UDIM" (Update, Disable unused, Identify users, Monitor logs) keeps your router and switch configs tight.
- Data Integrity Protection -
On a data integrity protection quiz, you'll need to know hashing algorithms like SHA-256 (NIST FIPS 180-4) and HMAC (RFC 2104) to verify messages haven't been altered. Example formula: HMAC = H(K ⊕ opad ‖ H(K ⊕ ipad ‖ message)). Memory trick: "SHAke hands for Integrity" reminds you that hashing secures data authenticity.
- Confidentiality Mechanisms -
To ace confidentiality non-repudiation questions on the SY0-501 exam, understand symmetric ciphers like AES (FIPS 197) and asymmetric ones like RSA (PKCS #1). Use the basic encryption formula C = E(K, P) and decryption P = D(K, C) to conceptualize how data stays private. Recall the CIA triad: "C is for Confidentiality spelled with Cipher" to tie the concept together.
- Non-Repudiation with Digital Signatures -
For confidentiality non-repudiation questions on your CompTIA Security+ SY0-501 practice test, digital signatures using private keys and X.509 certificates ensure senders can't deny their messages. A sender signs a message digest, and the recipient verifies it with the sender's public key, often with timestamping to prove when it was signed. Mnemonic: "Sign to Swear" keeps the commitment element top of mind.
