What is Bastionhost and what are the main functions of Bunker Bastionhost?

Bastionhost can protect and prevent internal and external damage in a designated network, so that important data and networks can run in a secure environment. Bastionhost has the function of cutting off the terminal computer to directly browse network and server resources.

At that time, there was an operation and maintenance personnel who had to assign accounts to hundreds or thousands of people at the same time, and if one of the accounts encountered problems or did anything to the system, it could not be traced.

Bastionhost is an O&M management and auditing system that uses various technical means to monitor and record the operations of O&M personnel on servers, system operations, security devices, databases, and other behaviors in the network to ensure the security of the network and data from intrusion and operation damage from external and internal personnel, and timely process and audit responsibility.

The so-called network security bastionhost is to add a security protection gate to the network, which can only pass through if the conditions are met, and if there are attacks and illegal commands, it cannot be entered, and all illegal access behaviors of the target are audited and monitored.

After using bastion host, you can prevent and manage chaotic access, verify identity permissions and blame access permissions, prevent internal operation errors and illegal operations, and effectively protect network security.

Bastionhost has six common features: single sign-on, management, identity authentication, resource authorization, access control, and operation auditing.

In a specific network environment, in order to protect the network and data from intrusion and damage from external and internal users, Bastionhost uses various technical means to monitor and record the operation and maintenance personnel of servers, network devices, security devices, databases, and other devices in the network, so as to provide centralized alarms, timely processing, and audit and determine responsibility.

Functionally speaking, it integrates the two backbone functions of core system operation and maintenance and security audit control, and in terms of technical implementation, it takes over the access of the terminal computer to the network and server by cutting off the direct access of the terminal computer to the network and server resources, and adopts the protocol to take over the access of the terminal computer to the network and the server. Figuratively speaking, the access of the terminal computer to the target needs to be translated by the operation and maintenance security audit. To use an analogy, an operational security audit acts as a gatekeeper, through which all requests for network equipment and servers pass.

Therefore, O&M security audit can intercept illegal access and malicious attacks, block illegal commands, filter out all illegal access to target devices, and audit and monitor the misoperation and illegal operation of internal personnel for subsequent responsibility tracking.

As an indispensable part of enterprise information security construction, security audit has gradually attracted the attention of users and is an important part of the enterprise security system. At the same time, security audit is an effective risk control means for pre-event prevention and in-process early warning, and it is also reliable evidence for post-event traceability**.

Centralized account management: Establish a global real-name management system based on unique identifiers, support unified account management policies, and achieve seamless connection with various servers and network devices.

Centralized access control: Through centralized access control and fine-grained command-level authorization policies, based on the principle of least privilege, centralized and orderly O&M operation management is realized, so that the right people can do the right things.

Centralized security audit: Based on the unique identity, through the audit of the user's entire operation behavior from login to logout, all sensitive operations of the user on the target device are monitored, and key events are focused on to achieve timely detection and early warning of security events, and accurate and traceable.
