Cheat Sheet
- Understanding service password-encryption -
When asked which statement regarding the service password-encryption command is true, remember it applies Cisco Type 7 reversible encryption to all plaintext passwords in the running-config and startup-config to thwart casual snooping (Cisco documentation). Mnemonic: "Type 7 for D7tEct!" reminds you it's a detect-and-hide, not a secure hash.
- Enable secret vs. service password-encryption -
Enable secret uses MD5 hashing and remains unaffected by service password-encryption, giving stronger protection by default (Cisco Systems). Think: "Secret is sealed, Encryption only hides."
- SSH key length best practices -
Per NIST SP 800-131A and as emphasized in CCNA Security Chapter 2 quiz materials, generate RSA keys of at least 2048 bits with "crypto key generate rsa modulus 2048" to ensure robust encryption for SSH logins (National Institute of Standards and Technology).
- Creating user EXEC commands -
Use "username <name> privilege <level> secret <password>" to create local accounts with appropriate EXEC privileges; levels 1 and 15 map to user EXEC and privileged EXEC modes respectively (Cisco Learning Network). A handy tip: level 15 = full admin access.
- Login command output analysis -
Differentiate "login" (uses default line password) from "login local" (prompts for username and password from local database); watch for prompts like "Username:" and "Password:" or "% Login invalid" to troubleshoot (Cisco Press).
