What are the main contents that system platform reinforcement should include?

The main aspects to pay attention to are: modifying the system password;Check whether the system has set the correct UMASK value; lock unnecessary system users and groups in the system; prevent flood attacks; disable X-windows services; strengthen the TCP/IP protocol.

Backup includes file system, key data, configuration information, password, user rights and other contents.

Specifically, security reinforcement mainly includes the following links: System security evaluation: including system security requirements analysis and system security status evaluation. Security situation assessment uses a large amount of security industry experience and vulnerability scanning technologies and tools to comprehensively evaluate the enterprise information system from the inside and outside, and confirm the security risks of the system.

Security reinforcement scope: Determine the equipment of computer equipment, network, database and application middleware involved in the collection of information systems that need security reinforcement.

Host reinforcement provides various protection means for any system to achieve multi-level and three-dimensional protection.

Host reinforcement is to provide various protection means for any system, which can achieve multi-level and three-dimensional protection. The main step is to delete unused applications. Repair the system regularly. Control network services. Disabled Windows services and ports as well as disabled remote services.

What are the operating system security reinforcement methods

1. Operating system security reinforcement methods Operating system security reinforcement mainly scans system vulnerabilities manually, and uses patching and strengthening accounts for the scanning results. Security, modifying security configuration, optimizing access control policies, adding security mechanisms and other methods to reinforce the system and plugging system vulnerabilities and "backdoors" to complete the reinforcement work.

2. In addition to boot partition encryption, there are many solutions that can meet the needs of each encryption level, including both commercial proprietary systems and open source systems that can be encrypted on each mainstream desktop operating system.

3. Do not connect the machine to the network before fully installing and configuring the operating system and installing all system patches for the system. When installing the operating system, it is recommended to divide at least three disk partitions.

4. Security reinforcement operations involve a wide range, such as correct installation of software and hardware, installation of the latest operating system and application software security patches, security configuration of operating system and application software, system security risk prevention, system security risk testing, system integrity backup, system account Smit password reinforcement and so on.

What is host reinforcement? Do you have a more detailed explanation?

1. Host reinforcement is the security reinforcement of the server system, which can prevent the invasion of Trojan viruses, prevent the core data from being destroyed, peeped, tampered with and stolen, and ensure the security of the system.

2. Host reinforcement is to provide various means of protection for any system, which can achieve multi-level and three-dimensional protection. The main step is to delete unused applications. Repair the system regularly. Control network services. Disabled Windows services and ports as well as disabled remote services.

3. Host reinforcement is to give the server a lock. The servers of the business system are very fragile, that isAnti-virus software has been installed, firewalls have been deployed, and patches have been patched regularly, but there will still be various risks, all kinds of poisoning, all kinds of intrusion, and the core data will still be peeped, destroyed, tampered with and stolen. Therefore, the server should be reinforced.
