Introduction

The Threat Log List page displays the logs generated by the IPS module and the anti-virus module. These logs help administrators customize IPS profiles and anti-virus profiles to improve network security.

When configuring an IPS profile or anti-virus profile, you can enable the logging function. The IPS module and anti-virus module can then generate logs for matching packets.

Restrictions and guidelines

·     Only one log operation (import, export, or delete) is allowed at a time.

·     Only one user can perform a log operation at a time. When you import, export, or delete logs, make sure no one else is performing a log operation.

·     When querying logs of a time range, this page displays the logs of the first day by default. You can click Previous Day or Next Day to view the logs of a specific date.

Configuration guidelines

Viewing threat log details

To view details of a log, click the Details icon  in the Details column. In the Threat Log Details window, the threat name in the Threat information area and the fields in the Packet Details area may be incompletely displayed. To view the complete content, you can use the following methods:

·     Hover over the content.

·     Click Copy. On the window that opens, obtain the complete content.

Downloading capture files

After the intrusion prevention system executes the packet capture action, the device generates logs. With hard disks installed, you can click Download of a log to obtain the captured file for threat analysis. To enable the device to cache IPS captured packets, execute the ips capture-cache number command in system view.

Adding to whitelist

If false alarms exist in the threat logs, you can click the Add to whitelist icon of a log to add the detected IPS signature ID and URL to the whitelist. The whitelist feature permits packets matching the whitelist to pass through, reducing false alarms.
