3 Tip for Cyber Security

Cyber security may not be the most exciting topic, but it is extremely important and it is everyone’s responsibility. There are some really basic things you can do to really increase your own security, both when doing business, as well as in your personal life.

Don’t reuse passwords

I’m sure you hear this one a lot, but a lot of times it’s not explained why!

Let’s say you sign up for the website www.reallyfancyclothes.com to do some shopping. You use your Gmail email address and the same password as the email address. Two months later, news breaks that reallyfancyclothes.com had their customer database hacked and all emails and passwords were stolen.

These hackers will use programming to test all those email/password combinations. Within a few minutes, they are in your Gmail account, because you haven’t secured it with multi-factor authentication!

Now that these hackers are in your Gmail, they are able to see what other websites you’ve signed up for. They can start either logging in using that same stolen password or doing a password reset to your email that they are logged into. Soon, all your accounts are stolen and you’re completely locked out of everything!

Always use Multi-Factor Authentication

You’ll notice in the above that I specified that the hackers were able to enter due to no Multi-Factor Authentication (MFA).

This is critical and is one example of why IT people use the term “defence in layers”.

Should you make the cardinal mistake of reusing passwords, you may still be saved by having MFA.

You will be familiar with this, it’s where you get a text with a one-time-use code, or you need to open an authentication app to get a short-lived code. MFA is not fool-proof, and there have been cases of people using social engineering to bypass these – but that’s why you have layers of security!


Never share passwords

Sometimes it may seem super easy and convenient to give your password to someone to log into your computer for you, but this is another cardinal sin of cybersecurity.

Once someone else knows your password, your account is no longer considered secure. You never know how that person is keeping that password (Did they write it down on a sticky note on their screen? Are they giving it to someone else to log in to?), and you can never know exactly what they will do under your login. And it’s not a stretch to imagine that someone working nearby may overhear your password, and then they can log into your account and wreak havoc!
