OpSec And Why It Matters To You

OpSec, or Operational Security, is the practice of keeping information secure through awareness of ones daily actions. We've all learned it at one time, imagine planning a surprise party and getting everyone involved to keep it a secret. Some (mostly funny) examples of OpSec failures:

• Hacker brags about taking down an airport website, leading to his arrest.
• People post photos of their debit cards and this Twitter account shames them with retweets.
• Bank robber shares photos of him with large amounts of cash, leads to arrest.

What I really want you to take away from this is a little voice in your head that asks "How can this be used against me?" before posting a photo or walking away from your computer unlocked in a public area.
