Imagine your iPhone as a mini Fort Knox, filled with treasures like photos, messages, and games. Just like the honest Fort Knox, your iPhone needs strong defences to protect your information from prying eyes. Released in 2016, iPhone OS 9.3.6 was an update for iPhones of the past. Let's explore how secure this version of the iPhone operating system was and how well it guarded your digital valuables.

Why Do We Need Security on Phones?

Our phones hold a lot of personal stuff, like funny texts, vacation photos, and maybe even banking apps. Security features on your iPhone act like guards at Fort Knox, keeping this information safe from anyone who shouldn't see it. With good security, you can use your phone freely without worrying about someone stealing your information.

Security Features of iPhone OS 9.3.6:

Like different guards at Fort Knox have different jobs, iPhone OS 9.3.6 has several security features working as your phone's bodyguards:

  • Encryption Magic: Imagine scrambling your treasures in the vault with a secret code. Encryption in iPhone OS 9.3.6 protected your information, making it unreadable to anyone who shouldn't see it, like a locked safe only you can open.
  • Touch ID & Face ID (on some models): Imagine a high-tech fingerprint or face scanner at Fort Knox! Touch ID and Face ID, available on some phones with iPhone OS 9.3.6, use your fingerprint or face to unlock your phone, adding another layer of security.
  • App Permissions: Imagine guards checking visitors' tools into the vault. App permissions let you control what information apps on your phone can access, preventing them from reaching your treasures without permission.
  • Secure Boot Process: Think of this as a double security check at the entrance of Fort Knox. The secure boot process in iPhone OS 9.3.6 ensured that only trusted software could run on your phone, making it harder for hackers to break in.

Vulnerabilities and Security Issues in iPhone OS 9.3.6

While iPhone OS 9.3.6 had these security features, it wasn't completely secure, just like Fort Knox might have had a few small cracks in its walls in the past. Here's why:

  • Past Security Breaches: Even with guards, there might have been cases in the past where hackers found ways to exploit weaknesses in iPhone security, similar to those tiny cracks.
  • Potential Risks and Threats: There could have been vulnerabilities (weak spots) in iPhone OS 9.3.6 that hackers could have potentially exploited to access your information.
  • Comparison with Others: While generally secure, iPhone OS 9.3.6 might not have been as robust as security features in newer operating systems at the time.

Be Your Guard: Taking Responsibility for Security

Security isn't just about the features on your phone; it's also about how you use it. Here's how you can be your security guard:

  • Regular Software Updates: Always download and install the latest updates for iPhone OS 9.3.6 if available. Frequently, these upgrades come with security patches that address flaws and enhance the overall security of your phone.
  • Password Power: Create strong and unique passcodes for your iPhone and online accounts. That makes it harder for someone to guess your password and access your information.
  • Two-Factor Authentication (2FA): If available, enable two-factor authentication for your accounts. Requiring your password and a code from your phone to log in provides additional security.

The Final Verdict: Security in iPhone OS 9.3.6

iPhone OS 9.3.6 offered a significant improvement in iPhone security with features like Touch ID and a secure boot process. However, it's important to remember that even the strongest forts can be challenged.

  • Upgrade When Possible: Consider upgrading your iPhone to a newer version with the latest security features. Newer versions typically have stronger encryption and more advanced security measures in place.
  • Be Cautious Online: Don't click on suspicious links or download apps from unknown sources. These can be tricks used by hackers to try and steal your information or infect your phone with harmful software.
  • Be Informed: Follow reputable tech news sources by informing yourself about the latest security threats and best practices. With this knowledge, you can guard against possible security risks and maintain vigilance.

The Future of iPhone Security:

The world of technology is constantly evolving, as are the methods used to exploit security weaknesses. Here's a glimpse into the future of iPhone security:

  • Constant Improvement: Apple is always working on improving security features in their iPhone operating systems. New updates and versions typically offer more robust encryption, granular app permission controls, and advanced features like improved facial recognition.
  • User Education: Users must keep up with the latest security risks and self-defence techniques as technology develops.
  • Shared Responsibility: Users and businesses like Apple share responsibilities for security. Apple creates operating systems with solid security components. Still, users must practice safe habits online and update their software.


By understanding the security features of iPhone OS 9.3.6, its limitations, and how to maintain a secure environment, you can take charge of your iPhone's safety and protect your valuable information. Recall that maintaining security is a process rather than a final goal. One last thing to consider:

  • Enjoy Your Phone Safely: By following these tips and keeping your iPhone OS updated whenever possible, you can confidently explore the vast digital world with your iPhone, knowing you're doing your part to keep your information safe and secure.
