A security expert has divided smartphone owners into five types. He gives appropriate security tips for every user group.

Before we introduce the five types of smartphone owners under the aspect of security, there are some reading recommendations on the subject of smartphone security in advance:

And now to the five types of smartphone owners from a security point of view:

1. The ignorant:

You use a smartphone because your boss or your children have urged you to do so, but you would be better off with a traditional cell phone: also known as a feature phone. HMD Global, for example, produces some exciting feature phones, aka cell phones, under the well-known brand name Nokia.

But now you have a smartphone and you cannot handle its functions and therefore only use the mobile phone for calls, SMS messages and e-mails. Finally, don’t download any apps unless you are guided through the process.

2. The minimalist:

You’re happy with your smartphone and only use it for basic things. Every now and then you download apps, but only the most necessary ones, such as WhatsApp, Instagram, Skype and Facebook. You keep your smartphone until it breaks and the minimalist is not interested in the latest models – even if the manufacturer no longer provides security updates for your smartphone.

Safety tip for these two groups

: “Both the ignorant and the minimalist should be especially careful when they click on links in emails and SMS messages, as they are not trained to detect malware,” believes Janus R. Nielsen, security expert at MYSecurityCenter. “Often it is these two groups who do not have passwords on their cell phones because they think it would be too complicated and are therefore more vulnerable if the cell phone is lost.

3. The enthusiast:

You find life difficult without your smartphone. All of your photos are on it, the majority of your communications go through the smartphone and you are curious to download apps to get even more out of your smartphone. You play various interactive games with the people around you and transfer money using mobile banking.

Safety tip:

Janus R. Nielsen advises this group of users: “You need to be extra careful when downloading apps – always read the ratings before installing them. If there are no comments or stars, do more research on the app online. Lastly, do it no mobile banking in public places with WLAN. ”

4. The extensive one:

Your smartphone is an extension of your arm, both at home and at work. They use it for everything and keep researching new features and apps to use it more efficiently. They have extensive technical knowledge of how your phone works and require a high level of security.

Safety tip:

“These types of smartphone users install virus protection on their devices so that they can detect, block and protect them if something should happen. Of course, these people are also exposed to potential WiFi hotspot risks, and attacks on public networks are increasingly common an attacker can disrupt and manipulate the transmission of information from your cell phone to the network.

5. The compulsive:

You replace your smartphone with a new one more often to keep up with the latest technology. To get the most out of your phone, delete some of the phone’s default programs to organize it the way you want.

Safety tip:

“Users are not aware that hackers open the phone’s SSH port, which means that anyone can potentially connect to your smartphone and steal or add data,” says Janus R. Nielsen. These users often install unauthorized third-party apps that are free but can easily add malware to their mobile phones. “The compulsive could, for example, benefit from a mobile VPN (Virtual Private Network) service, where they can connect to their home network or outside the house via encrypted channels, so that strangers are not able to follow the online surfing. ”

Safety tips for all smartphone users

1. Create the longest possible access code for your smartphone or use the fingerprint sensor.

2. Read reviews and comments before downloading an app. If there aren’t any, you’d better forego the app.

3. Read the terms carefully before accepting and downloading an app. For example, no puzzle game needs access to your messages or location.

4. Consider whether you might benefit from an antivirus that can track, block, or back up your data if it is lost. This applies to owners of an Android smartphone.

5. Be careful with public WiFi hotspots.

6. Remember that the guarantee does not apply if the smartphone is ‘jailbroken’ (the security structure is switched off).

7. Be careful with apps from unauthorized app stores as they can easily contain malware. It is best to only download apps from the Apple App Store and Google Play. The same goes for advertising in free apps.

8. Install all security updates for your mobile operating system.
