Password Management & Multi-factor Authentication

Password management is extremely important in Information Security because it allows a user to only need to remember a single password. Password management software works like a vault: Once you input the single password, it lists other websites and services with your usernames and passwords inside.  This is key because best Infosec practices include never using the same password on multiple services.  It can become unmanageable for a user to remember 10+ different passwords.

Data Destruction

Darins boot and nuke
Darin’s Boot and Nuke (“DBAN”) is a self-contained boot floppy that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.

DBAN is a means of ensuring due diligence in computer recycling, a way of preventing identity theft if you want to sell a computer, and a good way to totally clean a Microsoft Windows installation of viruses and spyware. DBAN prevents or thoroughly hinders all known techniques of hard disk forensic analysis.
