The so-called cloud computing is the use of the cloud for a variety of information services. In recent years, due to the emergence of fiber optic networks, cloud computing has been rapidly expanded, and the emergence of low-cost, large-capacity storage systems has made Cloud Storage widely used in daily life. Cloud storage can be said to be the successor to the USB flash drive. In addition to the previous file transfer, the file is the most common flash drive. However, the flash drive has the disadvantages of being easily lost and susceptible to computer viruses, which makes cloud storage gradually replace the flash drive.
In short, cloud storage means that the industry has placed a large-capacity computer in a fast network environment, allowing users to quickly store data in it. Therefore, uploading data to the cloud is equivalent to storing your own files on other people’s computers. However, this computer is fast and has a large capacity. It allows us to access any location, any time, and any network. Since there is a risk of storing data on someone else’s computer:
- Lack of stability: Although it is a high-level (large-capacity, fast-speed) storage system, there are also computer malfunctions that can result in the destruction of files. Traders often claim to have backup jobs, but there are unexpected circumstances. It is difficult to keep one day data from being destroyed and never returned.
- Transmission risks: The biggest limitation of cloud storage is that it must rely on network connection. In addition to the speed of network connection, the security between the connection is also very important. If there is no security protection during the connection, such as encryption, Data is easily stolen or stolen.
- Data leakage: There is no absolute information security, which means that the network storage company will still enter the files stored by the customer for inspection or copying. Well-known online storage companies have also encountered cases where hackers have infiltrated their accounts and stole a large number of account accounts that result in customer e-mail being confiscated by spam. Although afterwards, in addition to apologizing, the industry also quickly strengthened two authentication and other security mechanisms to prevent recurrence of intrusions. The incident, after all, is only a matter of remedy.
From the above, we can see that cloud storage has its insurmountable information security shortcomings. After all, there is absolutely no “absolute security” in practice. Although cloud storage is convenient, the harm it brings to privacy or data theft is sometimes even greater than the convenience of using it. For example, young people like to take self-portrait intimate photos and think they are on a password-protected network. It is absolutely safe, but in fact, even if network administrators do not steal, once the account password has been cracked by someone with heart, the reputation of one’s life may be destroyed. In addition, if you accidentally leak important confidential information at work, the consequences are quite terrible.
Therefore, in order to avoid unnecessary problems and protect your own data, you must pay attention to the following three points when using cloud storage:
- Back up important data: Although cloud storage can be said to replace local hard drives (hard drives in personal computers), in fact, cloud storage can only be used as a helper character, it cannot replace the function of hard disk, and it has its own price. A 500GB physical hard disk is about one-seventh of the price of a cloud drive in a year.
- Double-level authentication mechanism: Make use of the authentication mechanism provided by the cloud drive, such as: mobile authentication. One more level of authentication is one more level of security.
- Use SSL encryption: To avoid the theft of passwords or data in transmission, it is very important to use SSL encryption. The simplest way to determine is whether there is a string of “https:” in the address bar of the browser. Use encrypted transmission to allow Data is guaranteed more in transit.
- Don’t put privacy information on the Internet: The Internet is not absolutely secure, even if strict network protection also avoids the “negligence” of people or intentional harm, and privacy or confidential information should not be stored on the Internet. Avoiding regrettable lifetime events and causing irreparable faults.
- Strengthen security protection: Strengthen the security of personal computers or mobile devices, such as: update operating systems, update applications, etc., or install various protection software to avoid the harm of viruses or hacking software.
