The operation and maintenance auditing system ensures that deployment personnel carry out Agent deployment under the authorization permission of an administrator and an auditing administrator by authorizing operation and maintenance personnel and assets, avoids illegal personnel from installing agents to a server in a private way, and ensures that information is not illegally acquired. In addition, for authorized users, the system records all their activities at the server for auditing. No anyone audits the agent deployment process before and the parties participate in the deployment process, so that the invention ensures the authority and the safety of the deployment. Deploying an agent is a very unsafe thing, namely, the agent can get trojan horse by himself, and the agent can get endless once the supervision is unfavorable; not only is the safety/visibility ensured, but also the use convenience of the whole process is increased; the invention has two common laws on information safety, the more safe the information safety is, the more convenient the information safety is, the more unsafe the information safety is, and the invention also considers the two points.
The invention realizes safe Agent deployment, realizes playback of the deployment process, and multiple parties know that the original process is not monitored by people when company personnel deploy files to the server, and the invention realizes monitoring and is transparent; the system can audit playback in the process, and solves the problem of potential safety hazard of many companies.
Example 4:
an Agent deployment method based on a secure transmission protocol, as shown in fig. 3, mainly includes the following steps:
before deployment: the administrator can authorize the deployment and use functions of a certain server Agent to a common user, and the user can also apply for the deployment and use functions of the Agent to the administrator and wait for the administrator to approve. The authorization mechanism ensures that the person who has the right to deploy the Agent to the server and use its associated functions is a legitimate person.
In deployment: legal users enable the automatic deployment function in the safe deployment system, and the system background program deploys the Agent to the target server by using a safe protocol transmission channel (such as SSH protocol). When the same server is authorized to be deployed by a plurality of different users, if one user already deploys the Agent at the server, in order to avoid repeated deployment, the state table records the server IP and MAC address of the deployed Agent. Before the next deployment, the server will first go to the state table to inquire whether the Agent service is already opened. The Agent logs in by using a secret key authentication mode, if the Agent is not installed on a certain server, the first user can automatically generate a public key when deploying the secure deployment system and send the public key and the Agent to the server, and the private key is stored in the system; if the server is verified to be deployed with the Agent, the system automatically generates a public and private key pair, the private key is stored in the system, and the public key is automatically sent to the server. The whole deployment action is recorded by the background audit module and a related audit file is generated for future viewing.
After deployment: in order to enhance the security, the Agent on the server waits for the active connection of the security deployment system, so that the personal identity reliability of the remotely connected Agent can be ensured. The Agent encrypts the related information of the server through the previous secure transmission channel and then transmits the encrypted related information back to the secure deployment system, and the secure deployment system decrypts the content and then transmits the decrypted content to the user through the secure channel between the system and the user. This process is also recorded by the background audit system.
1. All the behaviors of the user are performed under the strict identity authentication control of the system, the behaviors of the user must be authorized, the whole action flow is transparent, and after the action is finished, a related audit log is recorded and stored, namely, the security audit can be performed.
2. The system automatically deploys the Agent tool on the designated server and performs corresponding configuration, and does not need manual deployment and installation, namely 'deployment and use'.
The invention realizes safe Agent deployment, realizes playback of the deployment process, and multiple parties know that the original process is not monitored by people when company personnel deploy files to the server, and the invention realizes monitoring and is transparent; the system can audit playback in the process, and solves the problem of potential safety hazard of many companies.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiments according to the technical spirit of the present invention are included in the scope of the present invention.
