Basic course in mobile security


The personal data on your smartphone is often worth more than the smartphone itself. The same applies to laptops and tablets. With the advent of smartphones and mobile technology, more and more people are facing security threats that lurk in their pockets.

Mobile technology has penetrated every corner of our everyday life. We use them for a wide range of tasks such as GPS location, entertainment, storage and much more. Cell phones may offer us endless possibilities, but the risks to our privacy are very real.

Mobile security

As we store more and more sensitive information on our mobile devices, it becomes more and more important to keep that information safe. From private photos and addresses to credit card details and phone numbers – hackers who gain access to our smartphones now have insight into more personal data than ever before.

Attacks on mobile devices can be divided into four categories: attacks on the operating system, app attacks, attacks by malware and communication-based attacks, for example via WLAN or Bluetooth.

Attacks on the operating system exploit security holes in the respective operating system. App attacks are usually the result of poor programming and coding. Attacks via communication networks occur when users log into an insecure or damaged network. Finally, increasingly popular malware can steal your photos, take over your camera, and delete important files.

Times change

Mobile security breaches are very different from attacks on your desktop PC. For one thing, „logging in” is now history, so to speak. Users no longer log in to their devices. This makes it difficult to get and share data between different applications.

In addition to personal photos, contacts and files, mobile applications also save confidential data such as passwords, authentication tokens and much more. It is therefore important to protect these files so that hackers cannot access your personal accounts.

Unlike the desktop PC, the mobile device does not display the entire URL of a visited website. This paves the way for scammers to launch phishing attacks against unsuspecting users.

Strengthening mobile security

There are a few things you can do to help protect your mobile devices. The first measure is to find out exactly what data is being collected by the apps you are using, e.g. B. Contacts, photos, internet data and call logs. You should also be aware of how these applications use your data.

Create different passwords for different apps and websites. Make up long, complicated passwords that contain letters, numbers, and symbols. Then set up a second protective layer in the form of a two-factor identification system.

Never use unsecure WiFi or Bluetooth connections and update your operating system and apps as soon as a new version is released.

It is entirely possible to protect yourself and increase mobile security. By carefully studying the risks and taking the correct precautions, you can maintain your privacy and security.
