Regardless of whether you’re working in the cloud, doing online banking, or surfing the Internet without a clear purpose, the risk of becoming a victim of a cyber attack is quite high. The number of network attacks on mobile devices is growing rapidly these days, and that’s mainly because smartphones and tablets are used almost everywhere. To protect your mobile devices, it’s imperative to learn how to improve mobile security. You can do this by simply reading the next seven tips.
1. Upgrade Basic Protection: Typically, basic protection includes built-in security settings and an antivirus program. It’s well known that even a simple password can discourage hackers from accessing your personal data. However, make sure that you replace the default administration passwords with new ones. Additionally, keeping built-in security settings and antivirus programs up-to-date is essential if you want to ensure full protection against regular cyber attacks.
2. Check before You Install: Never download and install an application without verifying its source. The easiest way to do this is to search for information over the Internet. If the source is reliable, one more thing you need to do is to use your antivirus program to scan the application before installing and running it on your smartphone or tablet.
3. Enable Router Firewall: Most advanced network routers have built-in firewall functions. For extra protection, combine the firewall function of your router with a personal firewall software program appropriate for your mobile device.
4. Disable “Auto-Connect” Function: Many mobile devices have an “auto-connect” function that enables them to connect to different hotspots automatically without notifying users. Enabling your device to connect to various wireless systems this way can cause a disaster. In this situation, the best thing to do is to unmark the “auto-connect” function and connect to networks manually.
5. Use a Static IP Address: Advanced mobile networks are preset to use dynamic IP addresses. Unfortunately, the technology making this possible works to the disadvantage of its users, even though it’s truly convenient to use. That’s because it permits hackers to obtain valid dynamic IP addresses that most devices can detect, facilitating network attacks. To improve your mobile security, replace your dynamic IP address with a fixed one.
6. Deactivate Wireless Connections: Keeping your wireless connections active all the time allows other people to access your data, including IDs and passwords. Luckily, this will be a thing of the past soon. Nowadays, more and more VPN servers use advanced technologies that encrypt traffic, preventing users from accessing data that isn’t theirs.
7. Use WPA/WEP Encryption: Many Wi-Fi devices available today support at least one form of encryption. The role of encryption technologies is to encrypt messages to make it impossible for other people to intercept them. To decrypt information, all of your devices must share the same encryption program and settings. As a related step, turn off the SSID broadcast of the router name. You and yours are the only ones who will need to know it and hackers often start with this information. In addition, there are programs that can encrypt both e-mail and voice messages on mobile devices for added protection.
These are the most basic things you can do to improve network security. To figure out the best approach, discuss the options you have with an IT professional who can direct you toward the most appropriate security alternatives. Considering what you can lose, it’s well worth spending some time and effort to protect your network.
