In today’s connected world, nothing is safe from hackers. Even 20-ft dams run by local governments are susceptible to hacking. Our entire lives live in our electronic devices, but even on the best days they’re at risk of being compromised. To avoid the horror of losing your health, personal, and financial information and having it abused across the web, follow these three tips to stay secure.

Get Smart About Your Passwords

If you think your password is more secure because you chose “qwerty1234” instead of just “qwerty,” then guess again. Your passwords need to be unique to you, unique to that site, and unique to the season. What do we mean by that? Password best practices state that every site you use should have a unique password (don’t just choose one for all of your logins), they should be virtually unguessable, and you should change them every few months.

If you’re worried about memorizing an endless string of letters, numbers, and characters, there’s a better solution out there. Lifehacker found that stringing three common words together offers unlimited security compared to picking a random word or number. Most random letters and numbers can be hacked in 8 months, but hacking actual words can take years.

Choose Your Wi-Fi Networks Carefully

Best practices say you should only access the Internet via secure wi-fi spots, but sometimes that’s not possible. The first step is identifying whether or not the networks around you are secure. This changes based on your device, but in general there should be a Connection Properties or Wireless Connection section. Click that and look under the Security Type tab. If there isn’t a security type or it says unsecured, then proceed with caution.

If you have to access an unsecure network, try to avoid visiting sites that would expose your personal information. This means wait to pay your credit card bill, stay away from your medical records, and avoid opening information from your employer. Your financial information might not be impressive, but if hackers can reach your company’s information through you then everyone is in trouble.

Consider Buying Additional Security Software

Most computers come with protection software that nearly unbreakable, but it might be worth investing in a data protection software if you have a large base of information that needs to be protected. There are many companies that specialize in cloud storage with an emphasis on security.

Depending on your needs, look for cloud storage that offers scalability if you’re launching a small business, more backup frequency if the data changes often, and a disaster plan in case of emergency. This way you have the flexibility to adjust your plan based on your needs.

The unspoken fourth point in this article is that you’re the biggest threat to hackers getting to your information. In fact, 94% of successful security attacks are the result of human error. The easiest way to protect your data is to be careful when accessing different websites and clicking into emails. Scammers are getting smarter about getting people to respond, and no amount of secure Wi-Fi connections and cloud software can help when you’ve opened your house to a hacker.
