Cloud server: Seven security secrets you don't know

The recent cloud server by the people fired very fire, some people who understand is constantly in the hype, some are not understand people everywhere consulting, this cloud server than the previous server in the end is there? Today's homepage June and you share some of this cloud server 7 Big security secrets.

"Secret one: Starting from the basic, timely installation of system patches" whether it is Windows or Linux, any operating system has vulnerabilities, timely patching to avoid vulnerabilities are deliberately exploited, is one of the most important guarantee of server security.

"Secret Two: Install and set up a firewall" there are now many hardware or software firewalls, and many security vendors have launched related products. Installing firewalls is necessary for server security. Firewalls have a good preventive effect on illegal access, but installing a firewall does not equal server security. After you install a firewall, you need to configure the firewall appropriately for your own network environment to achieve the best protection.

"Secret Three: Install the network" Now the virus is rampant on the network, this needs to install the network version of anti-virus software to control the spread of the virus, at the same time, in the use of anti-virus software, must be regularly or timely upgrade anti-virus software, and automatically update the virus every day.

"Secret four: Turn off unwanted services and ports" the server operating system starts some unwanted services when it is installed, which consumes the resources of the system and can also increase the security of the system. For servers that are completely unused for a period of time, you can shut down completely, and you should turn off unwanted services, such as Telnet, for the server you want to use during the period. Also, turn off TCP ports that are not necessary to open.

"Secret five: periodically back up the server" to prevent unpredictable system failures or user careless illegal operation, the system must be backed up securely. In addition to a monthly backup of the system as a whole, a weekly backup of the modified data should be performed. At the same time, the modified important system files should be stored on different servers so that when the system crashes (usually a hard drive error), you can restore the system to its normal state in a timely manner.

"Secret Six: Account and password protection" account and password protection can be said to be the first line of defense of the server system, the current online most of the attacks on the server system from the interception or guessing password start. Once the hacker entered the system, then the previous defense measures almost lost its role, so the server system administrator's account and password management is a very important measure to ensure system security.

"Secret Seven: Monitoring System Log" by running the System log program, the system will record all users using the system, including the most recent logon time, the use of the account, the activities carried out. The log program generates reports on a regular basis, and you can tell if there is an anomaly by analyzing the report.
