Android, developed by Google and active since 2007, is the world’s most used Mobile operating system—it has been adopted by millions of mobile users. Its simplified & an eye-catching User interface (UI), End-to-End encryption and security, robust architecture, Open-source platforms, and other useful features are the reason that it has attracted so many device manufacturers and End-Users.

Security, Encryption, Robustness and its Open-Source system have made Android the world’s most used operating system.

Android offers the following security to its users:

  • Android Application Sandbox to isolate app data and code execution from other applications.
  • An SSL certificate or HTTPS certificate protects the application code and App-server communication in public Wi-Fi zones and private VPN.
  • To eliminate Memory Management Errors, it uses ASLR, NX, ProPolice, safe_iop, OpenBSD dlmalloc, OpenBSD calloc, and Linux mmap_min_addr technologies.
  • It helps to encrypt the function of file system management, which is usually inbuilt in phone system by vendors to decrease the changes of data loss.
  • To restrict the access of some features and data it offers User-granted permissions and settings.
  • It offers application-defined permissions for controlling the application data for individual Apps.
  • Robust Security functions such as cryptography, permissions, and secure
  • OTA (Over The Air) updates, so the update will be rolled out directly to that particular user.
  • Verify Apps function, if the user is trying to install app from unknown sources.


Let’s talk about Android security with an SSL Certificate.

An SSL Certificate (aka TLS – Transport Layer Security) is a bridge between clients (Android App) and servers, which secures ongoing communication. So, when an Android user accesses an SSL certificate enabled application, SSL ensures the information shared will not be intercepted or accessible by any other person or robot.

While doing online transactions, accessing social media accounts, email accounts, social apps, accessing images and videos, synchronizing one app with another app/function, accessing banking apps, playing online games, etc. Security is needed most because Cyber Criminals may target applications directly or by injecting malware/threats into users’ devices. Lack of security in an android device can cause a user to become the victim of cyber-attacks. Public Wi-Fi ports can be even riskier, and are one of attackers’ favorite spots to dig into users’ systems.

SSL certificate offers a secured environment, which is vital to an Android user, whether the user is operating apps over Wi-Fi or using VPN, SSL will always protect the information.
