Check out the padlock sign to the websites to know whether they are fully encrypted. Accessing data from encrypted sites avoids the risk of falling victim to hackers. Many companies utilize the encryption feature to avoid incidences where they can lose sensitive data to the hands of hackers.

10. Shut Down Your Laptop/Computer When It's Not in Use

The most obvious step that you should take to prevent unauthorized access to your laptop or computer is to shut it down when it is not in use. 

After leaving the office, ensure that your laptop or computer is switched off to avoid cases where it will remain connected to the internet from where hackers can gain access and steal the sensitive data, although this might seem excessive, if you’re really trying to secure your computer from unauthorized access, taking these steps is crucial.
