As we all know, smartphones are often used for various business affairs, which is why they sometimes contain some sensitive information. These gadgets also collect your personal information and may share it with the perpetrators. This is probably the main reason why the security of mobile operating systems is facing new and quite high demands.
It may sound crazy, but the Android mobile operating system is considered the most secure. But with the development of the operating system itself and its massive spread, the number of viruses and other malicious applications has increased significantly. That's why today we're going to tell you how to make sure the information stored on your Android smartphone is 100% safe.
The first thing you can do here is pay attention to wireless networks, no matter what you try to connect to, the connection itself can be very dangerous. You should know that Wi-Fi networks are inherently dangerous and they are really vulnerable to all kinds of hacks and exploits. There are even mobile apps designed for hacking wireless connections, so evildoers can hack your phone using Wi-Fi with just a tablet or even a simple smartphone. It's also important to check your smartphone's settings, as many of them will try to connect to whatever network they have access to by default. It would be very helpful if you turned on the Wi-Fi module every time you didn't need it. Or simply use a portable wifi signal jammer to block all wireless connections in the area.
Similarly, Bluetooth invades various mobile devices. Previously it was seldom used due to inconvenience: hackers had to stay within a 10-meter (30-foot) radius of the target, as this is the range of Bluetooth reception. But now it's becoming popular because Bluetooth's working range has expanded. Sometimes, hackers may even use highly sensitive one-way antennas to accomplish these hacks remotely. Not many people use these connections in their daily lives, so it's best to turn them off. But if you need it sometimes - just set it to "undiscoverable" mode by default.
Now we come to the main security concern of all Android-based gadgets - malicious apps. Most of these viruses are fairly primitive, and their main goal is to send messages to short phone numbers or assign you to services that cost you extra. Their premium version may send a copy of it to your contact list. We should note that all these Android malicious apps request permission to send messages and call phone numbers.
But sometimes there are some very dangerous mobile apps that can not only steal your money, but also collect your personal information. Typically, these apps request permission to access your browsing history, contact list, and your device's physical memory. It will also try to gain unrestricted Internet access. If you see applications that are not related to Internet services requiring unrestricted Internet access, try to avoid them.
Additionally, mobile apps that can dial phone numbers can turn your phone into a bug, which is one of the main reasons why many offices or business centers install wireless wifi bluetooth jammer in their conference halls to keep company information safe.
It is very easy to protect your mobile device from the above mentioned mobile threats. Try to avoid installing apps from untrusted sources, you should also keep in mind that all activity of any mobile app requires your direct permission, by analyzing them you will be able to detect and avoid the most dangerous apps.
