If you want a new game or application for your smartphone, always head on to Google Play Store or Apple Store to download an application. In addition, get to know what are signs an app is from a trusted source or not.

  • Know how an application uses your personal information or what information it can access.
  • Read about the reputations and reviews of the application. You can also look for how many times the app has been installed. 
  • Check for monthly data usage of your phone. If you notice an increase in its data usage, you might have downloaded an app containing malware. Malicious apps with adware perform in the background without the user knowing about it.

Avoid Connecting to Public Wi-Fi

Free Wi-Fi is everywhere. You can easily find them in shopping malls, airports, coffee shops, hotel rooms, restaurants, and more. Many people connect to public Wi-Fi because it’s free. But sometimes, free stuff can come with a prize.

Public Wi-Fis aren’t secure. Even if it requires registration or a password to log in, connecting to a wireless source shared with other people makes your device and data vulnerable.

Anyone can learn how to hack into a Wi-Fi connection. They can simply watch a video or get tools that can help them. So, don’t take the risk with public Wi-Fis, especially when you manage your company’s data, shop, or anything that has to do with money and sensitive information.

However, whether we like it or not, everyone is tied up with their smartphones. Most people use their phones all the time, and so, connecting online for free is something some cannot avoid.

Here are some simple ways you can go online with free Wi-Fi and not risk your data:

  • Be wary of any link or Wi-Fi connection. Don’t assume or immediately consider that a Wi-Fi connection is legitimate. Ask the coffee shop, restaurant, or any place where you are using free Wi-Fi of the name and IP address to be sure.
  • Use a Virtual Private Network (VPN). VPNs are apps that will encrypt your data that goes in and out of the network. So, when cybercriminals are looking over your traffic, they won’t decipher the content. 
  • Don’t log in to websites that require you to input passwords or any sensitive information. Don’t perform any banking transaction with your smartphone or any device to prevent cybercriminals from seeing and stealing your data.
  • Use Mobile Phone Network instead of connecting to public Wi-Fi. You can safely access sites that require sensitive information like online shopping, banking, and more.

VPN tools you might want to try:

Use Strong Passwords

Using strong passwords to secure your accounts, smartphone, and applications can bring a lot of benefits. It can add an effective barrier to threats or hackers trying to access your account. So how to create a strong password? 

  • Think of unique passwords. Don’t use personal information that hackers can access, such as birthday, name of a pet, name of a family, and so on. 
  • Use more than 15 characters.
  • Combine upper and lower cases, numbers, and symbols. The more you combined these characters on your passwords, the more effective passwords you’ll have.
  • Don’t reuse or recycle passwords.
  • Use a password manager to store your passwords, so you don’t have to forget them all of the time.

Never Jailbreak or Root your Phone

If you root or jailbreak your phone, it gives you the freedom to customize and install the apps you need. However, performing this to your mobile’s operating system brings consequences.

Jailbreaking or rooting your mobile phone is more prone to attacks. Malware can easily inject their codes into your device when you install any infected application. In addition, you won’t get the latest security update as your device has been replaced or separated from your phone’s manufacturer. So, you won’t get the security updates you need, making your device vulnerable to threats.

Back up your data frequently as possible. Since we may never know when or who can gain access and steal our phones, it is best to secure your smartphone content by backing them up.

Regular backup is essential. There are plenty of ways to back up your data. You can sync your phone’s content to your computer or online. This includes emails, contacts, documents, and images.

There are also security software applications that include the backup feature as part of their package. With the option to choose which part of your mobile phone you want to back up.

Never Click on Links
