Viewing Server Alarms¶
The Events page displays the alarm events generated in the last 30 days. You can manually handle the alarmed items.
The status of a handled event changes from Unhandled to Handled.
Constraints and Limitations¶
To skip the checks on high-risk command execution, privilege escalations, reverse shells, abnormal shells, or web shells, manually disable the corresponding policies in the policy groups on the Policies page. HSS will not check the servers associated with disabled policies.
Other detection items cannot be manually disabled.
Servers that are not protected by HSS do not support operations related to alarms and events.
Procedure¶
Log in to the management console.
Click in the upper left corner of the page, select a region, and choose Security > HSS. The HSS page is displayed.
In the navigation pane on the left, choose Detection > Alarms and click Server Alarms.
Note
If your servers are managed by enterprise projects, you can select an enterprise project to view or operate the asset and scan information.

Server Alarms
Affected Servers
Number of servers for which alarms are generated.
Alarms to be Handled
Number of alarms to be handled.
By default, all alarms to be handled are displayed.
Handled Alarms
Number of handled alarms.
Blocked IP Addresses
Number of blocked IP addresses. You can click the number to check blocked IP address list.
The blocked IP address list displays the server name, attack source IP address, login type, blocking status, number of blocks, blocking start time, and the latest blocking time.
If a valid IP address is blocked by mistake (for example, after O&M personnel enter incorrect passwords for multiple times), you can manually unblock it. If a server is frequently attacked, you are advised to fix its vulnerabilities in a timely manner and eliminate risks.
Important
NOTICE:
After a blocked IP address is unblocked, HSS will no longer block the operations performed by the IP address.
A maximum of 10,000 IP addresses can be blocked for each type of software.
If your Linux server does not support ipset, a maximum of 50 IP addresses can be clocked for MySQL and vsftp.
If your Linux server does not support ipset or hosts.deny, a maximum of 50 IP addresses can be blocked for SSH.
Isolated Files
HSS can isolate detected threat files. Files that have been isolated are displayed on a slide-out panel on the Server Alarms page. You can click Isolated Files on the upper right corner to check them.
You can recover isolated files. For details, see Managing Isolated Files.
