Must Know These Electrical Power Issues for the Exam

All electrical power issues can affect availability and integrity of information security.

As a CISSP (and for the exam), you must be aware and ready to deal with each issue in regards to your organization.  This is going to be a short post on power issues, and from my studies, is required knowledge for the exam.

Power Issues

Too Much Power

  • Spike  High amount of voltage for a short time.

  • Surge  High amount voltage for a long time.

Decline of Power

  • Sag/Dip      Low amount of voltage for a short time.

  • Brownout  Low amount of voltage for a long time.

No Power

  • Fault         No power for a short time.

  • Blackout  No power for a long time.

Protection Mechanisms

Uninterruptible Power Supply

  • Serves as a backup power source in the event of a short power outage or times of voltage fluctuations

  • Protects against surges, spikes, blackout, brownout, faults…

Surge Protectors

  • Protects hardware and equipment from power fluctuations, such as changes in voltage

  • Protects against spikes, surges

Power Generators

  • Serves as a backup power source in the event of a long power outage

  • Protects against blackouts

Being a CISSP isn’t all about firewalls, risk analysis, or security frameworks.

Sometimes CISSPs have to just crawl under dusty desks and make sure things are plugged in and readily have power.
