In recent years, cloud computing has become the darling of the information security industry, and various companies have joined the cloud ranks one after another. The emergence of cloud technology has indeed brought great convenience to modern enterprises, but along with the benefits, there are also information security risks that cannot be avoided. Let’s share 7 measures to improve the security level of cloud servers so that enterprises can carry out targeted security protection. Start with the basics and install system patches in a timely manner. Whether it is Windows or Linux, any operating system has vulnerabilities. Timely patching to prevent vulnerabilities from being exploited by deliberate attacks is one of the most important guarantees for server security.
installs and sets up a firewall. There are many firewalls based on hardware or software, and many security manufacturers have also launched related products. For server security, installing a firewall is very necessary. Firewalls have a very good preventive effect on illegal access, but installing a firewall does not mean that the server is safe. After installing the firewall, you need to configure the firewall appropriately according to your own network environment to achieve the best protection effect. Deploy anti-virus software. Viruses are very rampant on the Internet now, which requires the installation of network version of anti-virus software on the network server to control the spread of viruses. At the same time, when using network anti-virus software, the anti-virus software must be upgraded regularly or in time, and the virus must be automatically updated every day. library. Close unnecessary services and ports. When the server operating system is installed, some unnecessary services will be started, which will occupy system resources and increase system security risks. For servers that will not be used at all for a period of time, you can shut them down completely; for servers that will be used during the period, you should also shut down unnecessary services, such as Telnet, etc. In addition, turn off the unnecessary TCP port . Make regular backups of your server. To prevent unexpected system failures or careless illegal operations by users, the system must be safely backed up. In addition to monthly backups of the entire system, modified data should also be backed up weekly. At the same time, modified important system files should be stored on different servers so that when the system crashes (usually a hard disk error), the system can be restored to normal state in a timely manner. Account and password protection. Account and password protection can be said to be the first line of defense for server systems. Currently, most attacks on server systems on the Internet begin with intercepting or guessing passwords. Once a hacker enters the system, the previous defensive measures are almost useless. Therefore, managing the account and password of the server system administrator is a very important measure to ensure system security. Monitor system logs. By running the system log program, the system will record the use of the system by all users, including the latest login time, accounts used, activities performed, etc. The log program will generate reports regularly. By analyzing the reports, you can know whether there are any abnormalities. From the above 7 secrets, we can learn the skills of server security protection, and we also understand the security issues that constitute cloud server . It is said that the cloud may trigger a revolution in data security protection. As long as the security of the cloud itself is ensured, its big data and high processing efficiency characteristics will increase the traditional IT security protection level several times, and the security factor will naturally increase several times. times. Once this doubled safety protection effect changes from quantitative to qualitative change, it will naturally cause a safety protection revolution. While we are looking forward to the arrival of this revolution, we must also clearly realize that cloud technology is still IT technology in the final analysis, and its own data security must be guaranteed. The most beneficial measure for cloud technology security is data encryption. In today's era, there are various ways of malicious attacks, and there is no more appropriate method to fundamentally protect data security than encryption software. Encryption software directly affects the data itself, ensuring that even if the data file is attacked and stolen, the encryption still plays a protective role and ensures the confidentiality of the data. Now that it is increasingly difficult to implement decryption algorithms, the encrypted data will not If it is used by criminals, it will not be made public.On the basis of encryption, the internationally advanced multi-mode encryption technology not only ensures the quality of protection, but also allows users to choose encryption modes independently in different environments, which is flexible and targeted. In order to avoid information security risks in the cloud, enterprises need to ensure that the solutions provided by cloud service providers have minimized security risks. At the same time, they must also do a good job in risk management to avoid the worst-case scenario that will cause serious losses to the enterprise. At this time, improving the security level, reducing security threats, and actively using encryption software to protect the security of the original data is the best choice!
