Avoid using birth names or dates because they are easy to guess.

7. Ignore Spam Emails

Sometimes hackers use phishing emails to trick computer users into clicking on links that install software that can lead to hacking. Avoid spam mail at all costs. Before a given email can be marked as spam, the email platforms such as google have applied their safety filters, and the emails have fallen short of the security tests. 

Avoid such emails to enjoy the highest level of security. There are cases where people have been exposed to losses after they end up opening spam emails. The email can have attractive headings, but the topics they are talking about are not of your concern in most cases. If something appears to be out of place, but it has landed in your mail, be cautious when opening it.

8. Secure Your Network Connections

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.

For people to access data from a given computer, it should be on. Shut it down, and they will find it hard to open it, considering you had enabled a password before the screen could unlock. The simple steps people take to secure their computers assure them the highest level of safety when handling the computers.
