The computer data is unsafe, and the data is leaking. What can I do to protect it? These problems are quite worthy of our attention. I have compiled the methods to ensure the security of computer data for you. Welcome to read!
Double-network isolation
Hackers are rampant, Trojans are rampant, and the network has also become a major way to leak data. This is especially true for security and sensitive data departments. How to avoid the outflow of intranet data without affecting the normal use of the network? Therefore, the dual-network isolated business machine came into being. Don't think that dual network isolation is just as simple as switching between two networks. In fact, there are two hard disks on the dual-network isolator. When switching between the internal and external networks, the computer uses different hard disks to prevent hackers from invading the computer and reading files on the hard disks, which will lead to the leakage of internal network data. Even the memory has been switched accordingly to prevent hackers from recovering files by reading memory data. This realizes the physical isolation between the internal and external networks and avoids the outflow of internal network data.
TPM security chip
TPM security chip is a chip that can generate and store keys and encrypt and decrypt files. Because its "ID number" is unique, files encrypted by one computer cannot be decrypted even if they are placed on other computers with TPM security chips. In this way, even if the hard disk is stolen, even if someone copies the data on the plane, as long as your data is encrypted, all he can see is a bunch of garbled codes.
note, when using TPM encryption, you must remember the password, because even the manufacturer can't crack this encryption. In this way, if you forget, you have to say goodbye to your data.
ID card data encryption
Data encryption has always been the strength of commercial computers, and many commercial computers have implemented hardware encryption to improve data security. But ah, this brings another big problem. What is the key? Only relying on passwords, data security is insufficient, and special keys, such as safe key and security card, will be inconvenient to cope with due to problems such as forgetting to carry them and losing them. Because of this contradiction, Yang Tian set his eyes on the second-generation ID card, so that everyone has the ID card and carries it with him, and the information stored in each person's ID card is different. Such a key is safe and convenient.
electromagnetic lock
under normal conditions, the electromagnetic lock inside the commercial machine has its locking tongue extended, which firmly locks the side plate and the chassis. Only after entering the BIOS to unlock, the electromagnetic lock is powered on and the locking tongue is retracted, can the chassis be opened normally. In this way, with the protection of BIOS password, the chassis is more secure. And locked inside the chassis, it is more difficult to be damaged. In addition, the lock is not exposed, which will not cause dissatisfaction in the hearts of users. This makes the electromagnetic lock a perfect match for many high-end business machines.
intrusion alarm
many commercial machines have a microswitch inside. with the support of BIOS, as long as the side panel is opened, the microswitch will be reset, thus sending an intrusion alarm to the host. Don't underestimate this simple microswitch, its function is very powerful. As long as the side panel has been turned on, even if it has been reset, when you use the computer in the future, the computer will still display an intrusion alarm and prompt the time when the chassis is turned on. With the support of the network, the computer can even send an alarm to the administrator to remind the administrator that the computer is turned on. With this little microswitch, if the thief tries to tamper with everyone in the office again, the fox's tail will be exposed.
fingerprint identification
with one stroke of your finger, you can easily turn on your computer, with a little thumb, and decrypt the data. Fingerprint identification is not only easy, but also safe. If you want to steal my data, do you still have the courage to hold my hand and press it up? Don't think that fingerprint identification is a patent for notebooks. In fact, we can see that small but useful fingerprint reader on keyboards and mainframes of many commercial desktops.
loss tracking technology
Lenovo, Sony, Dell and many other computer companies have made "lost &; Found "service, that is, relying on the cooperation with Absolute Software Company, once the user's computer is lost, the company will be notified. When the computer is turned on again, it will be locked, and the screen will show that this pc is a lost property, so you can contact the company and send it back to the notebook. This is somewhat similar to Intel anti-theft technology, which monitors lost computers through network software.
However, maybe your notebook didn't fall into the hands of good people, but was stolen by thieves. Never mind, Absolute Software also has a tracking service, which can record the IP information of a computer when a thief uses it. In this way, with the help of the police, the chances of getting the computer back are even greater. Unfortunately, such a good service is not available in China for the time being.
Intel Software Anti-Theft
Always floating in Jianghu, how can you not get stabbed! No matter how careful you are, you can't be sure that your laptop will be targeted by thieves and then disappear. At this time, you will worry about your data, and Intel's anti-theft technology can show its talents at this time. This technology mainly starts from the network software. As long as you haven't logged into the anti-theft network for too long, or the password is wrong too many times, or you report the theft of the control center computer, the computer system will automatically prevent the operating system from locking the hard disk or formatting the hard disk. In addition, the anti-theft technology will also prohibit access to the hard disk that has been encrypted with data, and even if the hard disk is transferred to other computers, the data cannot be read. In this way, the thief only gets a brick, and you don't have to worry about your data.
Chassis port mask
When no one is around, insert a USB flash drive and copy data-many companies' data were leaked. But no one can guarantee that the computer will be watched 24 hours a day. Therefore, covering the port with a mask and adding a lock, this method is simple, but it can well ensure the embarrassment that the data of window units and departments that are often accessed by outsiders are stolen.
Chassis lock
There are several small hooks at the upper side plate of the chassis and the box body, and then a small lock is locked, so that the computer can't be disassembled without unlocking, and the accessories in the computer are safe. Almost all notebooks are designed with anti-theft lock holes, so that the security of the whole machine is improved a lot by locking the computer with fixed objects, such as water pipes and computer desks. Although such measures are difficult to prevent thieves, they have a good deterrent and anti-theft effect on petty thieves who want to fish in troubled waters. Therefore, computers used in public places really need such simple security measures.
