Note

When managing Sky ATP with Security Director, you must select a Sky ATP realm from the available pulldown.

The C&C servers page lists information on servers that have attempted to contact and compromise hosts on your network. A C&C server is a centralized computer that issues commands to botnets (compromised networks of computers) and receives reports back from them. Botnets can be used to gather sensitive information, such as account numbers or credit card information, or to participate in a distributed denial-of-service (DDoS) attack.

When a host on your network tries to initiate contact with a possible C&C server on the Internet, the SRX Series device can intercept the traffic and perform an enforcement action based on real-time intelligence feed information that identifies the C&C server IP address and URL.

  • Export Data—Click the Export button to download C&C data to a CSV file. You are prompted to narrow the data download to a selected time-frame.

  • Report False Positives—Click the FP/FN button to launch a new screen which lets you send a report to Juniper Networks, informing Juniper of a false position or a false negative. Juniper will investigate the report, however, this does not change the verdict. If you want to make a correction (mark system as clean) you must do it manually.

The following information is available on this page.
