1. Do not click on links that you do not know.
If you have not learned this lesson from the previous long introduction, you are in real trouble! Suspicious links are one of the oldest and most dangerous methods of hacking devices, and you should pay attention to every link before you make the decision to click on it, especially those sent to you in SMS messages, e-mail messages, or even chat programs messages. In the event that you receive a message from a person or entity that you do not know, it is best to ignore the matter unless you talk to the sender to find out the nature of the web page that this link leads to and you find that he is a person who can be trusted and that the matter really matters to you. And even if I get a message from someone you know that includes a link, take a look at it, does it start with https? Ask the sender what this link is before opening, and make sure that it is the same person you know and not another person who managed to take over his account.
2. Don't make «Root» or «Jailbreak» to your phone
Really, there is no longer an urgent need to decrypt the protection of your device unless you are a developer who uses the phone for the purpose of experimentation only and not your personal phone that you depend on for everything. the phone. In the event that you choose to remove protection, it will give applications the power to access, control and change the system files itself as well, and your phone will be much more vulnerable to malware that will not fail to destroy your device, and when I say destroy the device, I mean what I say literally! For example, there is some malware that performs intensive operations at the same time, consuming the maximum power of the processor at work for a long time, causing the device to become very hot, which ultimately leads to the battery exploding from overheating.
3. Do not install apps outside of the official store
The restrictions imposed by Apple on developers and the severe strictness in reviewing applications before publishing them on the application store makes it very difficult to be surprised by the presence of harmful applications for your phone, and it may not have been this strict and strict on the Google store, but this does not mean that there is strong protection before and after downloading applications from the store . When you install an application from outside the official store, this will be entirely at your own risk, so it is not recommended to do so unless they are very popular and very reliable applications such as the famous game Fortnite, for example; That made the download from its own site and not from the Google store. Never leave the "Install unknown apps" option open so that an application on your device, or a link you clicked by mistake, does not download and install malicious software on your phone without your knowledge.
4. Update your system on a regular basis!
I am surprised by those who do not update their mobile operating systems despite the availability of new updates for them! The matter is very dangerous, as companies do not only add new features to operating systems, but also fill security holes and fix errors in the system, if a hacker discovered these vulnerabilities and you did not get the update yet, then your phone is in immediate danger. Whether it is the companies with operating systems or the companies that manufacture phones that design custom interfaces of the operating system, they have security teams to search for vulnerabilities and vulnerabilities in the system and then launch updates that get rid of them, so you should not underestimate these updates at all. This is also why you should not rely on a phone that is no longer receiving security updates for a long time, always try to have your current phone supported by the company to receive OS updates for as long as possible.
