Ever heard of ransomware? Criminals will delete your photos and other documents. Ever spilled hot coffee over your laptop? Ever left your mobile on the train?
A proper backup of your data will save you a lot of trouble. Ask around – almost everyone has a story to tell about broken laptops, stolen mobiles or infected computers.
It’s all about saving your data twice – once on your computer and a second time on an external hard drive or at least on a legally approved server or cloud.
Make a copy of your precious data regularly so you know you’ll have your latest pictures and documents if something unexpected happens.
Security technology is constantly evolving to keep up with criminal hackers’ technology.
All programs and applications you use are made by humans and therefore potentially contain mistakes. In terms of security, these potential mistakes can turn into vulnerabilities exploited by criminals.
To protect their clients, program providers work hard to fix every known vulnerability as fast as possible.
To be equipped with the latest security defences, your computer and smartphone must be up to date at all times.
Most software providers, like Microsoft or Apple, distribute updates automatically, so usually it’s very easy to stay up to date – you don’t have to do anything!
Sometimes an update requires your confirmation by clicking a button in a pop-up window. Even if updating means you’ll have to put some effort into adapting to new features or new-look the software, don’t postpone updates.
To receive updates, your computer must be connected to the internet. If you are travelling or just don’t use the internet for a while, it might take some time for all updates to be applied after reconnecting.
If you want to be certain, you can check your software’s version number in the menu and compare it to the latest version number published on the official website of the program or provider.
From the user’s perspective, the key to protecting data is choosing strong passwords. Think about it: access to almost all our data online is protected by our passwords.
Passwords are the most powerful security measure on the user’s side.
Criminal hackers exploit users’ laziness and carelessness. It’s sometimes easier for them to guess passwords to gain access to lucrative data than to try attacking a solid IT security system.
Strong passwords contain at least 10 characters and include numbers, upper and lower case letters and special characters.
And it is very important to have unique passwords. Passwords should never be used twice.
Use a tool to manage your passwords, like LastPass, Dashlane or KeePass.

If something is too good to be true, it usually is – especially on the internet.
Criminal hackers not only exploit technical systems but also try to manipulate you. Some of them use sophisticated psychological methods to make you reveal sensitive information or click a link.
You might have seen emails urging you to change your password by threatening to delete all your data. Maybe you once visited a website with a very tempting offer. Or maybe you’ve received a call from someone claiming to be with ‘Microsoft Support’ telling you to install some software.
Be suspicious of seductive offers of any kind (shoes, money, jobs, love…).
Take your time. Even if you’re told to do something urgently, take a minute and think about whether following the request is right. Passwords are never to be passed on, and internal information is shared only with assigned colleagues.
Call back. Every time you’re not sure whether an offer or request is a fraud or not, check on it. If you receive an email sent by your colleague but the request and language are unusual, call your colleague and verify the email. In case of a phone call, tell the person you’ll call back after verifying the request.
Have you caught a computer virus or fallen victim to some sort of fraud?
If you suspect that your computer or phone has been hacked, don’t hesitate to get help.
Experts can identify whether your devices are infected and tell you what needs to be done to repair them.
If one of your business devices is affected, ask your IT department for help and advice. They might also respond to questions regarding non-work-related security issues or tell you who to ask or where to fix your problem.
For your personal devices, your local IT vendor is a good place to start.
