I believe many inexperienced people don't know what to do about the seven security protection techniques of CVM. This article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Although the cloud host has many benefits, there are also hidden dangers of information security that you do not want to touch. Now that enterprises have chosen to take advantage of the benefits of cloud technology, of course, there are ways to solve the security risks in the cloud.

With the popularity of cloud computing, all the words with "cloud" have become popular. As an important part of cloud computing in infrastructure applications, cloud host is naturally unboiled water. Although the cloud host has many benefits, it also has security risks that you don't want to touch. Now that enterprises have chosen to take advantage of the benefits of cloud technology, of course, there should be ways to solve the security risks in the cloud. Here are some tips on the security protection of this CVM.

Start with the basics and install the system patch in time

No matter Windows or Linux, any operating system has loopholes. Timely patching to prevent vulnerabilities from being deliberately exploited is one of the most important guarantees of server security.

Install and set up the firewall

Now there are many firewalls based on hardware or software, and many security manufacturers have launched related products. For server security, it is necessary to install a firewall. Firewalls play a good role in preventing illegal access, but the installation of firewalls does not mean that the server is secure. After installing the firewall, you need to configure the firewall properly according to your own network environment to achieve the best protection effect.

Install the network

At present, the virus on the network is very rampant, so it is necessary to install the network version of antivirus software on the network server to control the spread of the virus. At the same time, in the use of the network antivirus software, the antivirus software must be upgraded regularly or in time, and the virus database is updated automatically every day.

Shut down unwanted services and ports

When the server operating system is installed, it will start some unwanted services, which will occupy the resources of the system and increase the security risks of the system. For servers that will not be used at all for a period of time, you can shut down completely; for servers to be used during the period, you should also turn off unwanted services, such as Telnet. In addition, turn off TCP ports that are not necessary.

Back up the server regularly

In order to prevent unexpected system failures or careless illegal operations of users, a safe backup of the system must be carried out. In addition to the monthly backup of the whole system, the modified data should also be backed up once a week. At the same time, important system files that have been modified should be stored on different servers so that in the event of a system crash (usually a hard disk error), the system can be restored to normal in a timely manner.

Monitoring system log

By running the Syslog program, the system records all users' use of the system, including the most recent login time, accounts used, activities carried out, and so on. The log program will generate reports on a regular basis, and by analyzing the reports, you can know if there are any anomalies.

Account and password protection

Account and password protection can be said to be the first line of defense of the server system. At present, most attacks on the server system start from intercepting or guessing passwords. Once the hacker enters the system, the previous defense measures are almost useless, so managing the account and password of the server system administrator is a very important measure to ensure system security.
