Principle of Least Privilege

Malware (short for malicious software. e.g. Virus, Trojan Horse, Worm, Adware, etc.)

  • The key to solving the malware problem is avoidance, not detection and removal.
  • Rootkit : You can never be sure you’ve removed all traces of a rootkit. The only way to be certain that your system is clean of malware is to:
    1. Backup only your data. (Do not backup any .exe’s, .com’s as they may have been compromised.)
    2. Erase/format the hard drive
    3. Do a clean install of the operating system from known safe media. (Do not use the recovery partition, as it may have been compromised too.)
  • Live AntiVirus and Recovery Discs
  • KNOPPIX Live Disc
    • Download via the “Get Knoppix” menu

BadUSB

PortaPow Fast Charge + Data Block USB Adaptor

  • Blocks data transfer – your device will not go into ‘data transfer’ mode if connected to a computer, so you can use a computer just like a mains charger. This also prevents data hacking and any risk of viruses being loaded onto your device when charging from an unknown/public USB socket.
  • Puts your device into fast charge mode – allows you to charge at high speed (up to 2.4A) from a computer USB socket or other USB charger even if it was not originally designed for your device. Most Android and Apple products will charge at double the speed of normal computer USB charging.
  • Available from Amazon.com

Backing Up: 3-2-1 Rule

  • 3: Have three copies of your files. The original, plus 2 copies
  • 2: On different storage mediums. e.g. separate hard drives, optical (CD/DVD), tape
  • 1: Have a current backup that is offsite and/or a secure online service:

Optical Media for Long Term Archives

  • Regular writable optical media, CDs & DVDs, etc., are not reliable for long term storage. The die used with optical media degrade with exposure to light, temperature extremes, etc. Because of this, the data on the media will start to degrade within 1 to 5 years.
  • M-DISC (Millennial Disc) is a write once optical disc technology available in DVD and Blu-ray forms.
  • Millenniata claims that properly stored M-DISC DVD recordings will last 1,000 years, and are readable in conventional optical drives.
  • Drives with M-DISC support and M-DISC Media

Live AntiVirus and Recovery Discs
