Hardware firewall is an important barrier to ensure the security of internal network. Its security and stability are directly related to the security of the whole internal network. Therefore, the daily routine check is very important to ensure the security of the hardware firewall. Many hidden dangers and faults in the system may appear before the outbreak. The task of routine check is to discover these hidden dangers and locate the problems as far as possible to facilitate the solution of the problems.
1. Strong ability to defend against DD/CC attacks
The high defense server has two main characteristics to defend against large traffic attacks. The first is the high bandwidth occupied by the traffic, and the second is the firewall traction system with intelligent identification of traffic. Therefore, the defense capability of DD/CC attacks is very strong.
2. More compatible operating environment
Hard defense server rental in addition to support WEB, FTP and other services, but also their own configuration environment, installation components, erect and other services, and virtual space may not be compatible.
3. Fast network access
The network access speed depends on the actual equipment room line and server location.
4. Independent operating system
The mysql, Sendmail, SSH, HTTP, FTP and other systems that can be used normally on the hard server are independent, which is different from virtual space, because the hard server server is used for personal use, not shared, so it has higher security, performance and control freedom than virtual space.
5, protect network security, good protection effect
A hard defense server is rented and has an independent IP address. A hard defense server is called a high defense server because it is an anti-attack server and has good anti-attack capability, so it does not need to worry about malicious attacks.
6. Data backup migration
Hard defense server, users can quickly backup, simple operation, provide mirror, live migration and other data backup assistance services, game server rental.
The Internet has become an indispensable part of our lives, but security risks are creeping into our interests and privacy.
First, set the permissions and attributes of system files on the Web server;
On the Web server about the administrator rights to be allocated, for the documents that can be accessed by people to allocate a public group, and only assign read-only rights, all HTML files belong to this group, by the web administrator management of this group, for the Web configuration file only to the Web administrator have the right to write.
Second, attention should be paid to Web server account opening;
1. Restrict the opening of accounts on the Web server and periodically delete some users who are disconnected from the process.
2. For accounts opened on the Web server, relevant requirements should be made on password length and regular change to prevent stolen use.
Third, periodically review the log logs file on the server.
Periodically check the log files in the server and analyze all suspicious events. When rm, login, /bin/perl, /bin/sh and other records are generated in the errorlog file, the server is likely to have been invaded by some illegal users.
