In fact, this is a particularly related thing to whether our equipment is safe and whether it runs smoothly. The so-called "that is to find vulnerabilities for the device's firmware and then block such an operation. You should know that this firmware is like the soul of the device, and it is in charge of many basic operational matters of the device.
So why is this so important? Let’s talk about this first. Once there is a security loophole in the firmware, it’s amazing. Those who are ill-hearted outside can enter our equipment like loopholes. For example, some webcam devices have firmware vulnerabilities. After the criminals enter, they can secretly obtain the camera's content. Our surrounding scenes, some private areas are exposed.
Let’s divide the module into the key content:
1. There are quite a lot of channels for detecting vulnerabilities . Many manufacturers have special vulnerability detection tools. In order to detect vulnerabilities in their products, manufacturers first write programs to detect the firmware situation. This is very common. There are also some third-party security service platforms that specialize in this security detection job, which is relatively rich in data and experience.
Let’s talk about the manufacturer’s own tools first . The advantage is that it is familiar with the firmware of its own products. Can quickly find the special loopholes in your own products.
As a third-party platform , this is a strong comprehensive analysis. Can integrate data from multiple different products. These two channels are more safe and secure at the same time
2. Treat the update process with caution .
Before updating the firmware, we need to back up useful data of this device. If we accidentally update abnormal data, we can find it back. Don't be stupid and work just
Then when downloading the firmware update program, you have to download it from the serious manufacturer's website
After that, set up the instructions in our hands. Step by step, it's not just a blind eye to get in
Let's talk about a specific comparison
For older styles, the firmware update frequency is often not that high. So I am worried that there are more loopholes. Some new technologies have been launched soon, and manufacturers also pay great attention to monitoring optimization. Updates are pushed from time to time. From the update rules, we can also have a basic judgment on its security.
After talking about module knowledge, some friends will have some questions. Let’s answer:
Q: Can you regularly scan one-click vulnerabilities of important devices and solve them all?
Answer: In reality, this is not very feasible. The specifications and performance of this equipment are different. It is difficult to identify and eliminate all hidden dangers.
Q: Is there a big difference between emergency repair and ordinary ones?
Answer: It's quite big. Emergency repairs are often used for serious immediate risk scenarios. Ordinary planning time and relaxed updates are mainly considered from the long-term aspects of prevention and stability.
Q: What should I do if the network is always disconnected during updates?
Answer: Disconnecting the connection is troublesome, it is best to switch to a more stable network
During this update process, the equipment needs to be connected to the network. If the connection is disconnected, the firmware may be a half-finished project
We personally think it is very necessary. In this era of cumbersome network environment, information related to each device is always important. So don’t miss the major loopholes such as firmware repair, as it may break out and it will be difficult to control. Do a good job in filling in loopholes and running the equipment, and subsequent data security will be much more stable. If the equipment needs to be used for a long time, it will be considered for a long time. If the equipment is implemented for a long time, it will be the only way to do it.
