Apple's iPhone and iPad all run under the iOS system, which is pretty secure. But hackers and cybercriminals never ignore any chance or flaw to attach an iOS device. You are the owner of your iPhone and private data on your iPhone, so it's your job to keep them safe, although iOS provides an excellent security framework.
Here we summarize some tips to maximize the iOS security features for those who have concerns about the safety of sensitive information, from contact lists to photos and videos.
1. Update Software
Any software may have flaws or defects, especially in new features. Hackers are always trying to find them in iOS coding to exploit, potentially to access to user's data.
As the primary security protection, Apple works hard to figure out these flaws and patch them as soon as possible. It is why you get notifications to update iOS from time to time, which is the critical way of combatting the exploits.
Therefore, you should ensure your iOS is the latest version, and shouldn't miss any release, even if the minor updates. When a new iOS update is ready, you need to confirm the update before it is installed. To update to the latest version of iOS, go as follows:Settings > General > Software Update
. Here you can see that you're already running the latest version or need to install something newer.
Some iOS updates are particular to fix security flaws. For example, iOS 13.1.3 was rushed out to fix the issues and security flaws in iOS 13.0. So, for your privacy in iPhone, never miss any iOS update.
2. Password and Password Management
Password is the key to open your iPhone and get everything stored in it. You may know some hacker tools can crack simple iPhone and iPad passwords quickly. Typically, a four-digit password needs a couple of hours, and a six-digit one needs a few days.
You may think iOS can delay and lock the device to stop anyone from brute-forcing or guessing your password. Yes, Apple does its best against cracking user credentials. But hackers stand on the other side; they think such a thing should be possible. So, create a complicated password is a severe task to protect your iPhone:
- Choose a code longer than six digits. Hack an eight-digit pin needs months, and a ten-digit pin needs a decade;
- Use a code includes numbers, letters, and symbols. It should make your iPhone a lot harder to break.
Even if your iPhone is secured by Face ID or fingerprint, but it can still be unlocked with your password. So never set it as 1-2-3-4, which will cause big trouble for your privacy.
Steps to set password:
- Open Settings
- Tap Touch/Face ID & Passcode
- Enter your Passcode
- Tap on Change Passcode
- Enter your Passcode
- Tap Passcode Options
- Enter new code and verify it
Password is playing a pivotal role in keeping personal information secure in iPhone and other computers or smart devices. A password manager can make life a great deal easier, which helps you use one password to access the manager and then takes care of all the rest.
Apple offers a password manager iCloud Keychain that integrated with both iOS and macOS. Your iPhone can use it to up security levels. If your devices aren't only from Apple, you can also choose third parties' password managers. Your iPhone can work together will mainstream ones.
3. Auto-Wipe Data
If your iPhone indeed has sensitive data, there is an option to destroy them when someone wants to crack your password. The idea is that after ten incorrect logins, the iPhone will automatically wipe all content. In case any hacker gets your iPhone, it will be useless to unless he hits its password in 10 tryings.
The steps are as follows:Settings > Touch/Face ID & Passcode
, enter your passcode, scroll to the bottom and toggle on Erase Data.
This feature will wipe your data from iPhone after ten times of wrong password. If you accidentally activate the feature, your data will be gone too. So if you enable the option, you should back up your iPhone's data in case sometime you need them to re-load. The iCloud is the right place to automatic backup.
4. Revoke App Permissions
If you install apps into your iPhone, it will bring up new security issues. If your app is from Apple Store, you can trust that the Store already did a security analyze on it. However, you should know what data (like contact and email) or resources (like camera and microphone) it will access, and grant it permissions accordingly.
So, if an app abuses your data, there is no matter with iPhone. It's why you should revoke unused permissions per app, and be very careful to handle every installed apps.
Now Apple has made it harder for apps to gather personal data without your knowledge. Some new concerns are as follows:
- Choices to sharing your location: Allow continuous location access
- Location Reminder Alert with a map
- Use Bluetooth
- WiFi tracking: apps could track your location by looking for WiFi networks
- Get information stored in the notes section of contacts
If you feel that you've installed an app that you don't trust with full confidence, you can either delete it or go toSettings > Privacy
, select the permission to revoke and toggle the application off.
