  1. ALE=ARO*SLE
    Annualized Loss Expectancy = Annualized Rate of Occurence (% in a year - eg if it dies every 4 years then this value is .25) * Single Loss Expectancy (cost of replacement) - this one's pretty simple - don't make it complicated
  2. BCP, DRP, BIA, MTD
    Business Continuity Plan, Disaster Recovery Plan, Business Impact Analysis, Maximum Tolerable Downtime
  3. AES
    symmetric, bulk data encryption
  4. DES
    symmetric, 56 bit. used for LM
  5. 3DES
    symmetric, 3 passes of DES, 128 bit
  6. RSA
    asymmetric, SSL/TLS
  7. RC4
    stream cipher - voice and video CC's, symmetric, used by ssl and tls for web encryption
  8. Blackboard
    KB or DB of information to contribute to solving a problem. Bayesian, AI
  9. MD5
    symmetric - used by NTLM, 128 bit hash, 32 character output
  10. Risk = Threat * Vulnerability
    • Threat - frequency or rate of potential negative event¬†
    • Vuln - likelihood a threat will be successful (often a %)
  11. SHA1
    Symmetric, 160  bit hash value, 40 characters
  12. Syskey
    40 bit encryption
  13. XOR
    • Both same = 0
    • Either Different = 1
  14. subnet address
    also known as network address, not to be confused with broadcast address
