A Crash Course in Cybersecurity

You lock your front door and don't give strangers your bank card. Many people do exactly the opposite online. Often without realising it. Your smartphone is full of personal data: Emails, photos, banking, tickets, accounts. And yet, many people are often surprisingly careless with it in their everyday digital lives. So here's your crash course in cybersecurity.

​

Lock your device - Always

Your smartphone is half your life and yet, it is often lying around unlocked or only half-heartedly protected. This is exactly what makes it the easiest access point for others. Lock code, fingerprint or face ID are not extras, but absolutely mandatory. Anyone who has your unlocked mobile phone in their hands can access your data faster than you would like.

​

Updates are annoying, but crucial

Updates always come when it's not convenient. So you click them away. The problem: it's not just about new functions, but above all about closed security gaps. And it is precisely these gaps that are actively exploited. Ignoring updates makes it unnecessarily easy for attackers. The most relaxed approach is to activate automatic updates.

​

Not every app has to be allowed to do everything

An app can be installed quickly and access to location, contacts, camera or microphone is just as fast. Much of this is not even necessary. So it's worth doing a quick check: Does the app really need all these authorisations? And where does it even come from? Apps from official stores are generally more secure. When it comes to access rights, it is better to allow too little than too much.

​

One password for everything is not a good idea

Now you have to be strong. Or at least stronger than the password you've been using for all your accounts since primary school. Because that is precisely the problem: as soon as a password is leaked somewhere, it is automatically tried out on other services as well. That's why you should use your own passwords for important accounts. And if you don't want to memorise them, a password manager can help.

​

Two factors make the difference

A password alone is often no longer enough. With two-factor authentication, a second step is added, for example a code on the mobile phone. It is an essential step where financial transactions are involved. This may seem like a small diversion in everyday life, but it makes a big difference in an emergency. Even if someone knows your password, they won't automatically get any further.

​

Public Wi-Fi is practical, but not for everything

People like to use free Wi-Fi: in the hospital, restaurants, at the airport or in the hotel. It's usually no problem for scrolling or checking messages. For sensitive things like logins or payments it is an issue. Open or poorly secured networks are more vulnerable. That's why it's better to use mobile data for sensitive matters or make a conscious decision about which network to use when.

​

Phishing messages today often so real

Many attacks still start with a simple message: email or text. They want to get you to click quickly or enter data. The patterns are surprisingly consistent:

• The news comes unexpectedly

• It creates pressure ("act immediately")

• You should click on a link or enter data

​

What is new above all is how well the whole thing is done. News today seems clean, plausible and often fits perfectly into your everyday life. That's exactly why it's worth taking a short break. It's often just a small detail that's wrong.

​

AI helps you and unfortunately also fraudsters

Maybe you've already used AI to write emails or pimp your CV or for images and quick searches. With tools like these, you can often reach your goal faster and work more efficiently. The problem is that attackers use exactly the same tools. Messages today are often error free, convincing and sometimes even tailored to you. Therefore, don't rely on recognising fraud immediately. Take a few moments before you click or enter data. This check is becoming increasingly important.
