Threats to computer data security and corresponding solutions

With science and technology developing rapidly, computer users are experiencing great impacts while being troubled by disturbing issues such as computer data security. As is known to all, data stored in computer are always of great significance. Once those data are lost due to certain reason, users are most likely to suffer from severe consequences. However, what can users do to protect data from being lost or damaged to the largest extent? Actually, users are supposed to get familiar with possible threats to the exact factors which will pose threats to computer data security. Well then, we will make a brief introduction.
There are multiple possible reasons which will pose risks to computer data security. Firstly, data may be lost or damaged as a result of system crash, which greatly impinges on hard disk. Secondly, computer data are likely to get corrupted due to faulty hard disk, hard drive or power failures. Thirdly, accidental deletion, formatting, partitioning and overwriting can cause data loss. Fourthly, with computer virus getting rampant, data residing in computer always become victims. Fifthly, man-made factors like malicious deletion and altering will cause computer data to be lost. At last, force majeure factors including natural disaster, acts of terrorism, war, etc will cause data loss.
Solutions to protecting data from being lost After knowing possible factors which will generate computer data loss or damage, users may wonder how to protect data from being lost or damaged. Here, multiple effective measures for computer data security will be introduced. 1.  Users should always keep in mind that to provide for a rainy data is an excellent attitude for excellent computer data security. Therefore, users are supposed to develop a good habit of backing up data regularly. Speaking of data copying, there are several available backup strategies including full backup, incremental backup and differential backup, and those three backup strategies can be employed alternately so as to save time and energy. 2.  Users are expected to install anti-virus software and make sure that that such software are updated timely if they want to ensure computer data security. Some users mistakenly believe that the updating speed of anti-virus software always lags behind that of computer viruses, thus it useless to install such software on computer. Actually, certain software is able to protect data to some extent. 3.  Users should log off, turn terminals off or lock them after they finish browsing web pages, otherwise malicious users may take advantage of those information to make profits. 4.  Users are supposed to set write-protecting, which can greatly protect data from being accidentally deleted. If users take the mentioned measures demonstrated above, they will guarantee computer data security to a large degree. However, it is far from being enough. Aiming at data recovery after data loss, we recommend users to resort to data recovery tools. Benefitting from data recovery tools, users can recover data lost due to various factors such as accidental deletion, formatting, partitioning and even computer virus invasions.
