Checking Monitoring Statistics
Scenarios
SecMaster provides one overall situation screen and four mission-specific screens: monitoring statistics, asset security, threat situation, and vulnerable assets.
Before participating in cybersecurity drills, ensure that you have completed self-checks and rectifications and cleared all alerts.
If you are security personnel on duty during the drill, you need to focus on the data on the Monitoring Statistics screen. When an alert pops up, you need to handle it promptly and clear all alert data.
You can analyze alerts based on the data on the alert details page. If other log data is required, you can query and trace the source in the corresponding data pipeline through security analysis. You can close false alerts without taking any other actions, and block risky alerts in just one click.
Checking Monitoring Statistics
- Log in to the SecMaster console.
- Go to the target workspace.
- In the navigation pane on the left, choose Situation Awareness > Large Screen. Figure 1 Large Screen
- Click Play in the lower right corner of the Monitoring Statistics image to open the screen. In the Unhandled Alerts area, click the alert description for an alert to go to the Alarm Details page.

Troubleshooting Typical Alerts
| Alert Type | Security Layer | Dependent Data Source | SecMaster Intelligent Model | Handling Suggestion |
|---|---|---|---|---|
| Typical alerts in the reconnaissance phase | Network protection | NIP attack logs | Network-High-Risk Port Exposure to the Outside | Check whether the source IP address is connected to high-risk ports in the system for service purposes. If the connection is necessary for services, modify the model script to ignore the source IP address. If the connection is not necessary for services, modify the inbound rules of the corresponding security group to prevent high-risk ports from being exposed to the public network, or block the source IP address. To ensure system security, disable unnecessary ports. |
| Typical alerts in the reconnaissance phase | Application protection | WAF attack logs | Application - Source IP Conducting URL Traversal | Emergency handling can record all access requests and responses, detect attacks in a timely manner, and restrict or block attack source IP addresses. You can configure a blacklist policy to block attack source IP addresses. |
| Typical alerts in the reconnaissance phase | Application protection | WAF access logs | Application - Possible source code leakage risks | Emergency handling can record all access requests and responses, detect attacks in a timely manner, and restrict or block attack source IP addresses. You can configure a blacklist policy to block attack source IP addresses. |
| Typical alerts for attack attempts | Application protection | WAF attack logs | Application - WAF Key Attack Alert, Application - Possible Apache Shiro vulnerabilities, Application - Possible Log4j 2 vulnerabilities, Application - Possible Java framework common code execution vulnerabilities, and Application - Possible Fastjson vulnerabilities | Contact the service owner to check whether the web server has related vulnerabilities and whether the attack is successful. If there are vulnerabilities, promptly fix them and harden the system. If the attack was successful, combine threat indicators to block attack IP addresses. |
| Typical alerts for attack attempts | Network protection | NIP attack logs | Network - Hacking tool detection and Network - Login Brute Force Alarm | Check whether the operation was performed by authorized personnel. If not, take the following steps:
|
| Typical alerts for attack attempts | Network protection | CFW access control logs | Network - Suspicious DoS attacks | Check whether the operation was performed by authorized personnel. If not, block the IP address on related network devices. |
| Typical alerts for successful intrusion | Network protection | NIP attack logs | Network - Command Injection Alert | If the source or destination port is an uncommon port, such as 4444, 8686, or 7778 (most suspicious ports are four digits), contact the owner to confirm the service scenario. If service behavior is abnormal, the system may have been injected with malicious commands. In that case, check service and host logs to identify whether the intrusion succeeded, and block attack IP addresses if necessary. |
| Typical alerts for successful intrusion | Network protection | NIP attack logs | Network - Malware (worms, viruses, Trojans) detection | Disconnect the network from the Internet immediately to prevent malware from spreading or stealing data. Then, use system restoration or antivirus software to scan and remove malware. |
| Typical alerts for successful intrusion | Server protection | HSS alert logs | Host - Brute Force Attack Success, Host - Abnormal Shell, and Host - Abnormal Location Login | Check whether the attack is successful. If the attack is successful, the server is compromised. In this case, isolate the server to prevent risks from spreading, and then harden the compromised server. |
| Typical alerts for successful intrusion | Server protection | HSS security logs | Host - Hidden processes and ports and Host - Abnormal file attribute modifications | Check whether the operation was performed by authorized personnel and if the operation was intentional. If the process is abnormal or the file contains malicious behavior, run the related command to stop the process. |
| Typical alerts for defense evasion | Server protection | HSS alert logs | Host - Rootkit Events | Immediately check whether the Rootkit installation is caused by normal service operations. If not, terminate the installation immediately and check the entire system based on HSS alerts. |
| Typical alerts for permission maintenance | Server protection | HSS alert logs | Host - Reverse shell and Host - Malware | If an intrusion is confirmed, contact the host owner, log in to the host, stop the malware, and delete malicious files. Then, check for suspicious processes, open ports, active connections, and startup items to eliminate any remnants. Additionally, use other methods for a comprehensive assessment. |
| Typical alerts for permission maintenance | Network protection | NIP attack logs | Network - Abnormal connection detection | Check whether the behavior is a real abnormal behavior instead of a false positive or misjudgment. To do so, you can view log records and use network monitoring tools. If an abnormal connection is confirmed, immediately disconnect it and eliminate the malware to prevent further security issues. |
| Typical alerts for lateral movement | Server protection | HSS security logs | Host-Virtual Machine Lateral Connection | Review audit logs in bastion hosts or other tools to check NICs. If NICs are attached manually by unauthorized users or ECSs are under attack risk, take measures in a timely manner. |
| Typical alerts for persistent control | Network protection | NIP attack logs | Network - Backdoors | Disconnect the network from the Internet immediately to prevent backdoors from spreading or stealing data. If needed, use antivirus software to scan for and remove backdoors, and search for and delete suspicious files to ensure system security. |
| Typical alerts for persistent control | Server protection | HSS security logs | Host - Malicious scheduled tasks | Check whether the task is a normal service task. If not, disable the scheduled task. |
