  • Confidentiality
  • Integrity
  • Availability

Availability Threats:

Things must be consistently available because if they aren't it is likely that things won't work properly which can cause a lot of issues.

Examples:

  • Crowdstirke
  • UVM Cyber Attack
  • 2012 Aramco & Shamoon
  • 2014 Sony Hack

Risk Analysis

  • Redundancy is expensive
  • Disaster Recovery Site Options
    • Hot: A MAJOR Crisis that will cost a lot of money
    • Warm: A less major problem but one that should be handled ASAP - Will cost less but is still expensive
    • Cold: A low-level security issue that should be handled quickly to avoid further issues but is much cheaper than the scenarios listed above.
  • Types of failover like sites
  • Disaster recovery means
    • Data replication, offsite backups
    • Networks - High availability options
    • People
  • More complex issues
    • Who goes to the site backup?
    • During a disaster, who is really going to the backup site?
    • Who is actually critical?

You're far more likely to run out of $$$ before the security problem runs out.

If your default gateway fails you can use the static route
