More About the Course
The key to countering cybercriminals is first to be aware of the methods they use and then to intentionally close off those avenues. This involves a combination of technology and common sense.
The vast majority of hacks occur because of weak, easily guessed passwords. Just like a real-world criminal would rather use a stolen key than break a window, there’s no reason for hackers to bother with complicated exploits when they can log in to your sensitive accounts in a seemingly legitimate way.
Some of the most common factors that make passwords guessable include:
- Using any of the 100 or so most common passwords
- Failing to change a device’s default password
- Basing passwords on publicly available information like your name or birthday
- Using a short password (five characters or less) that can be guessed in random attempts
- Using the same password on every site
The last bullet point is extremely important and is the reason why data breaches are so dangerous. If you use the same password for every account, your entire identity is only as strong as the weakest site you’ve used it on. Venmo may have reliable security, but if you log in with a password that was compromised in a breach elsewhere, your money is still forfeit.
You can foil 80% of cyber threats simply by using passwords that hackers can’t guess. Don’t worry, though — that doesn’t mean you have to spend your whole day sorting out 100 different strings of random letters and numbers.
