iOS is not a completely secure operating system. And the reality is that there is none that is. The software, by definition, displays constants vulnerabilities that developers must solve version after version. For example, just a month ago, Apple recognized that there was a set of holes in the mail application that would allow an alleged attacker to execute code remotely. Fortunately, Apple arrived on time and fixed the problem with iOS 13.4.5.
The fact that there is no software capable of offering a unbreakable security does not mean that, as users, we should resign ourselves. There are certain actions that we all must carry out if we want to improve the security of our devices. What to do to improve the security of iOS? Here are some tricks.
6 tips for a safer device
Delete apps that we don’t use and think before buying and installing
Possibly, in our device we have installed some apps we don’t actually use. On many occasions we installed them to test them and, although they did not convince us, they are still in our terminal. This is a security risk, especially if they are applications that are hardly updated.
It is important that when we make purchases and downloads in the App Store, we avoid doing it impulsively. It does not hurt to take time to read the reviews and check that there are no users who have had bad experiences. As for the applications related to our finances or our health, it is advisable to always use the official applications.

Keep the device always updated
Updates to the operating system are the cornerstone of security. As we have already mentioned, developers apply security patches when they update the devices. Therefore, it is vitally important that we always have the latest version to have the highest possible level of protection.
How to know if we are up to date? In the section general from the settings we can check that we have the latest version. In addition, Apple alerts the user when there is a new version of iOS through pop-up messages and with the notification badge on the icon of the Settings application. It is also recommended that we activate the Automatic Updates if we want to be more carefree.
Control the permissions we grant to applications
Our smartphones have become true data collection centers. And it is that the list is endless: our physical state, our location, our voice, our photos, our contacts …
Many third-party applications also request access to data that they don’t really need. In this regard, it is notable the case of some flashlight applications that ask for permission to obtain the location, access the camera or consult the contact list. Therefore, if we want to increase security and, incidentally, privacy, it is vitally important that let’s take time to examine what permissions we have granted to each application. This is possible thanks to the complete Privacy section of our iPhone or iPad.
Use an alphanumeric code
The access code It is still mandatory, for many biometric systems that we have activated. Ultimately, this code is the one that will allow us to unlock our iPhone or iPad if the set of built-in sensors does not work. So it is very important to have a strong password.
Decreasing the chances of an attacker accessing our device without permission is as simple as going from a four-digit numeric code to one alphanumeric. This change can be made in the Touch ID or Face ID section of the iOS settings.
Set a limit of access attempts
Access by brute force It consists of extracting a password by trying different combinations until you find the correct one. iOS allows us to set a limit of access attempts that would prevent this. When the 10 attempts are exceeded, the iPhone will be completely erased.
But be careful, this may be a double-edged sword. It is true that, if our phone falls into the wrong hands, this system allows our data to be kept safe. But if we are prone to forget the code, we could activate the full erase of the iPhone ourselves and lose valuable information. However, if we regularly do full backups, be it in iCloud or through iTunes, then we don’t have to worry.
Improve security and privacy when browsing the Internet
Safari has some interesting options that can help us improve security. For example, we can prevent sites from making monitoring our activity to show us advertising based on our tastes. On the other hand, we can block popup windows and enable a warning when we enter a fraudulent portal. We can find these options in Settings> Safari.
Admitting our responsibility in this regard is also important. Being careful with the content we download, the websites we visit or what links we open is essential to maintain a safe environment. And if what we want is to increase our privacy when we search, Safari allows us to change Google for other more respectful options, such as DuckDuckGo.
Do not connect our iPhone or iPad to public Wi-Fi networks
In most cases, public Wi-Fi networks they are safe. However, we may be in for an unpleasant surprise if we use these access points for tasks that include the use of our personal data. For example, it is not a good idea to carry out procedures with our bank or Internet purchases connected to a public network.
Many criminals create fake public Wi-Fi networks and, when the user has connected, intercept their data. Therefore, if it is strictly necessary for us to connect to a public network, we can use a VPN It may be the solution to avoid attacks. In this way, our activity will be encrypted and will not be accessible to other users on the same network.
