CBH enables common authentication, authorization, account, and audit (AAAA) management. Users can obtain O&M permissions by submitting tickets and can invite O&M engineers to perform collaborative O&M.
Credential Authentication
CBH uses multi-factor authentication and remote authentication technologies to enhance O&M security.
- Multi-factor authentication: CBH authenticates users by mobile one-time passwords (OTPs), SMS messages, USB keys, and/or OTP tokens. This allows you to mitigate O&M risks caused by leaked credentials.
- Remote authentication: CBH interconnects with third-party authentication services or platforms to perform remote account authentication, prevent credential leakage, and ensure secure O&M. Currently, Active Directory (AD), Remote Authentication Dial-In User Service (RADIUS), Lightweight Directory Access Protocol (LDAP), and Azure AD remote authentication are available. CBH allows you to synchronize users from the AD domain server without modifying the original user directory structure.
Account Management
With a CBH system, you can centrally manage system user accounts and managed resource accounts, and establish a visible, controllable, and manageable O&M system that covers the entire account lifecycle.

Feature |
Description |
|
System user accounts |
CBH enables you to grant a unique account with specific permissions to each system user based on their responsibilities. This eliminates security risks resulting from the use of shared accounts, temporary accounts, or privilege escalation.
- Batch importing
CBH enables you to synchronize users from a third-party server or import users in batches, eliminating the need to create users repeatedly.
- User groups
CBH allows you to add users of the same type in a group and assign permissions by user group.
- Batch management
CBH enables you to manage user accounts in batches, including deleting, enabling, and disabling user accounts, resetting user passwords, and modifying basic user configurations.
|
|
Managed resource accounts |
With a CBH system, you can centrally manage accounts of resources managed in the CBH system through the entire account lifecycle, log in to managed resources by using SSO portal, and seamlessly switch between resource management and O&M.
|
Permissions Management
CBH supports fine-grained permission management so that you have complete control over which user can access the CBH system and which managed resources can be accessed by a specific system user, enabling you to safeguard both the CBH system and managed resources.

Function |
Description |
|
CBH system access permission |
You can assign permissions to a system user to log in to a CBH system and use different functional modules in the CBH system according to the user's responsibilities.
- System user roles
CBH supports role-based and module-based permission management so that you can allow a system user to access specific functional modules based on the user's responsibilities.
You can use default user roles or create custom roles by adding various functional modules.
- Departments
CBH enables department-based system user management, allowing you to specify departments of different levels for each system user. There are no limits on the number of department levels.
- Login restrictions
CBH controls system user logins from many dimensions, including login validity period, login duration, multi-factor verification, IP addresses, and MAC addresses.
|
|
Managed resource access permission |
You can assign permissions for resources by user, user group, account, and account group.
- Access control
You can control resource access by resource access validity period, access duration, and IP address. CBH also allows you to assign permissions to users for uploading and downloading files, transferring files, and using the clipboard. When an O&M initiates an O&M session, the watermark indicating their identity will be displayed in the background of the session window.
- Two-person authorization
You can configure multi-level authorization for users, allowing them to access to a specific resource, and thereby safeguard sensitive and mission-critical resources.
- Command interception
You can set command control policies or database control policies to forcibly block sensitive or high-risk operations on servers or databases, generate alarms, and review such operations. This gives you more control over key operations.
- Batch authorization
You can grant permissions for multiple resources to multiple users by user group or account group.
|
Operation Audit
In a CBH system, each system user has a unique identifier. After a system user logs in to the CBH system, the CBH system logs their operations and monitors and audits their operations on managed resources based on the unique identifier so that any security events can be discovered and reported in real time.

Resource O&M audit |
A CBH system records user operations throughout the entire O&M process and supports multiple O&M auditing techniques. It audits user operations, identifies O&M risks, and provides the basis for tracing and analyzing security events.
- Auditing techniques
- Linux command audits
For command operations through character-oriented protocols (such as SSH and Telnet), a CBH system records the entire O&M process, parses operation commands, reproduces operation commands, and quickly locates and replays operations using keywords in input and output results.
- Windows operation audits
For operations on terminals and applications through graphics protocol (such as RDP and VNC), the CBH system records all remote desktop operations, including keyboard actions, function key operations, mouse operations, window instructions, window switchover, and clipboard copy.
- Database command audit
For command operations through database protocols (such as DB2, MySQL, Oracle, and SQL Server), the CBH system records the entire process from single sign-on (SSO) to database command operations, parses database operation instructions, and reproduces all operating instructions.
- File transfer audits
For file transfer operations through file transfer protocols (such as FTP, SFTP, and SCP), the CBH system audits the entire file transfer process on web browsers or clients, and records the names and destination paths of transferred files.
- O&M audit methods
- Real-time monitoring
Ongoing O&M sessions can be monitored, viewed, and terminated.
- History logs
All O&M operations are recorded and history session logs can be exported with just a few clicks.
- Session videos
Linux commands and Windows operations can be recorded by video.
Video files can be downloaded with just a few clicks.
- Operation reports
CBH uses various reports to display O&M statistics in one place, including O&M action distribution over time, resource access times, session duration, two-person authorization, command interception, number of commands, and number of transferred files.
Operation reports can be exported with just a few clicks and periodically sent by email.
