Mobile security in 2021. Best practices for iOS/Android ordinary users and mobile developers.
Scroll

With the era of public/private 5G, cloud, and remote working, mobile data protection has taken on new relevance. Security leaders and experienced developers contend with a growing variety of challenges, as cybercriminals are targeting mobile users more actively than ever before. In addition, security researchers claim that both Android and iOS apps are still unsafe. According to Gartner, 75% of mobile applications would fail security tests. At the same time, over 1000 Android apps gather location information, even when you forbid them to do so.

Security issues

In this context, it becomes quite obvious that both users and developers should do their best to prevent the invasion of privacy and other cyber threats. There’s nothing like working in tandem and joining efforts in applying security standards. Customers can start by setting a strong passcode, using random passwords, and disabling ad tracking. 

Today we want to share other simple but effective ways to decrease the likelihood of security issues. We’ve divided this post into two parts to give you iPhone and Android essential privacy and security tips. Let’s talk about effective practices for users first and then dwell on security tips for developers. 

App security for iOS: five practical tips 

App security for iOS

If you are determined to turn your mobile phone into a more secure device, then keep up reading. The same principles are paramount when it comes to protecting your tablet from data leaks. 

  1. Enable two-factor authentication

As the name implies, two-factor authentication provides your Apple account with a second layer of security. So when you log in from a new device, you need to enter a one-time-use code and a password. And hence, even if someone has your password, it won’t be enough to assess your account without a computer or phone.

  1. Adjust what’s accessible on your lock screen

Because otherwise, your iPhone may display personal data or certain features without requiring your passcode. Take a look at features available on the lock screen in the Allow Access When Locked area. For instance, you may disable Return Missed Calls, Notification Center, or Reply with Message features. 

  1. Consider app permissions

Numerous apps require your location to track where you are shopping, while users tend to click through notifications mindlessly. Open the Privacy area and make sure that location services are set to Never or While Using. As for weather apps and other applications that need approximate location only, disabling Precise Location is a good idea. If you use mobile apps for business and seek extra security, you may take full advantage of our IT security services. Just click on the link. 

  1. Check how much data applications collect

You can find three sections under the App Privacy area in the App Store: data not linked to you (motion sensor data), information related to your identity, and data used to track you. Inside these sections, there are 14 kinds of data apps may gather about you. The simplest way to check out privacy is to open the App Store, tap your icon, and find My purchases setting. It’s better to use the app with relatively short labels. Also, pay particular attention to applications with data used to track you. Don’t hesitate to contact mobile development experts and get more information. 

  1. Use Sign-in with Apple function

With the help of this feature, your account can be hidden behind a random email address that forwards to your real one. All you have to do is consider creating an account with your Apple ID. 

How to make your IOS application secure without great effort?

  • Utilize SSL/TLS protocols for “man-in-the-middle” attack prevention. SSL certificates must be 2048 bit-keys based. It would take over 6,4 quadrillion years to break the last generation certificate.
  • Don’t keep important data locally if you can avoid it.
  • Choose URL schemes for extra-validation. 
  • Exclude malicious SQL statements from your application’s databases. 
  • Double-check which network resources the application can get access to.
  • Don’t forget to cover your back-end by selecting reliable server-side authentication.

Top tips for Android apps protection

Android apps protection

It’s time to discuss how to protect your personal information when using Android devices. 

  1. Install anti-malware applications

As a rule, leading antivirus companies have their own Android-malware applications, such as Avast, Norton, or Kaspersky. You can get a robust AV app for free, namely Lookout and TrustGo.

  1. Keep sensitive information behind an extra encryption layer

Nowadays, there’s no point in keeping extra-sensitive data on your tablet or mobile phone. Download applications that store data behind double encryption and protection. File Hide Expert and mSecure are at the top of our list. 

  1. Download a remote wipe/lock app

Numerous applications on the Google Play market enable owners to wipe or lock their gadgets in case of theft. Cerberus and Avast Mobile Security react to a text command or you can utilize them via the web interface. 

  1. Try to avoid unknown Wi-Fi networks

Such cheeky goldmines are sometimes related to a ‘middleman’ attack when the third party acquires personal details, including your credit card number. 

  1. Use internal storage and avoid particular modes

This tip will be useful for those who are thinking about creating an on-premise app and hiring Android developers. You should know that all the documents you keep on internal storage are available only for your app. Try to avoid both MODE_WORLD_READABLE and MODE_WORLD_WRITEABLE for your IPC files. These modes fail to provide control of data format as well as limit data access to particular apps.

Here we’ve put together a list of security features for Android developers:

  • The Android Application Sandbox, designed to isolate code execution and your app itself from other applications.
  • Cryptography, permissions, and secure IPC — critical parts of an application framework.
  • ASLR, NX, ProPolice, OpenBSD dlmalloc, OpenBSD calloc, and Linux mmap_min_addr that deal with the risks related to common memory management errors.
  • An encrypted file system aimed to protect information on lost gadgets.
  • User-granted permissions for restricting access to user information and some system features.
  • Application-defined permissions to manage important information on a per-app basis.
