Phishing Emails

We are currently living in the phishing email era. 

Thousands of people are scammed each day due to their own negligence and this is an easy threat to avoid

Always confirm the email sender. 

Don't recognize the sender? Ignore/Delete it.

These emails usually contain an attachment or a link asking for your personal information, such as login details etc.


The olden days pirates of the high seas have been replaced by a very tech savvy new breed of pirate, or as more modernly called, a hacker.

Ransomware has unfortunately become part of our daily lives.

These "your data has been locked and pay me in x currency" scams are running rampant and usually recovery is very unlikely.

Which leads us to the next section.

The 3-2-1 backup rule

Lackluster backups are one of the easiest ways to give yourself sleepless nights.

The international IT community has set the standard for backups as the 3-2-1 backup rule.

  • Always have 1 primary backup of your data and 2 copies thereof

  • Always have your backups in 2 different types of media

  • Always have one backup file offsite.

Have you tried switching it off and on again?

You would be surprised at the amount of IT issues that can be resolved with a mere restart.

Your IT support's first question will always be "have you tried switching it off and on"

And only one restart is sufficient.

Backup power

One of the easiest ways to cause data corruption is to let Eskom switch off your computer for you.

You might even be unlucky enough and it never switches back on again.

You don't need a state of the art inverter system.

An entry level UPS will give you sufficient time to power down in a healthy manner.
