The same is used for security, what is the difference between a bastion machine and a firewall?
What is a bastion machine?
The bastion machine is an operation and maintenance security audit system for internal operation and maintenance personnel. The main function is to audit and control the operation and maintenance operations of the operation and maintenance personnel. At the same time, the bastion machine also has the functions of centralized account management and single sign-on.
As the gatekeeper of the IT system, the bastion machine has a very strong ability to strictly control and control, and can block illegal access and malicious attacks to a large extent, block illegal commands, and filter out all illegal access to the target device. , and audit and monitor the misoperation and illegal operation of internal personnel, so as to track the responsibility afterwards.
However, auditing is an after-the-fact behavior, and auditing can find problems, but cannot prevent problems from occurring.
For example, anyone can only log on to the system through the bastion machine as a portal. The bastion machine can centrally manage and assign all accounts, and more importantly, the bastion machine can strictly audit and control the operation and maintenance operations of the operation and maintenance personnel to ensure the security compliance of operation and maintenance and the minimum authority management of the operation and maintenance personnel. The emergence of security that can protect enterprise network equipment and server resources makes enterprise network management rational and professional.
What is a firewall?
A modern firewall generally refers to a network firewall, which is a piece of software that sits between a computer and the network to which it is connected. All network traffic to and from the computer passes through the network firewall. A firewall scans the network traffic that flows through it, which can filter out some attacks before they can be executed on the target computer. Firewalls can also close unused ports. And it can also block outgoing traffic on specific ports. Finally, it can block access from special sites, preventing all communications from unknown intruders.
What is the difference between a bastion machine and a firewall?
The firewall is the gatekeeper between the private network and the public network, and the bastion machine is the gatekeeper between the internal operation and maintenance personnel and the private network.
The role of the firewall wall is to separate, no one can get through, but the bastion machine is different. His function is to check and judge whether it can pass, as long as it meets the conditions, it can pass, and the bastion machine is more flexible.
In general, some network restrictions can be made between the company's internal network and the company's external network through firewalls. Computers in the company's internal network can be accessed through the Xingyun butler bastion machine to provide unified access and provide operation and maintenance. Audit and dangerous command interception and other functions. Xingyun Butler fortress machine is the leading brand of operation and maintenance fortress machine in China. It has accumulated and accumulated in the field of IT operation and maintenance for 10 years. It is also the first operation and maintenance fortress machine on the market that supports Windows2012/2016 system operation command audit.
