S749 Alert

After releasing signature update S749, we discovered a defect that significantly impacted the performance of the AnalysisEngine application running on the sensor. This defect is documented in CSCul00198. Having identified the root cause of the problem, we have provided a fix in signature update S750 and enhanced our test suite to detect this condition in future signature updates. In order to avoid this issue do not upgrade to S749 (it is no longer available for download); instead, upgrade directly to S750. We apologize for any inconveniences this may have caused.

Do you need to report a false positive? If you believe you have identified a benign trigger, please provide the following information and we will determine if the signature can be improved. Include the signature and sub-signature id, traffic sample(s), alert context buffers, and any additional relevant information.

Need a custom signature? Is there specific traffic you want to identify on your network? Do you think that the signature would be useful to other customers? We can provide guidance on developing a custom signature. If it is universally applicable, we may be able to test and maintain it by releasing it in our standard signature set. Please include a detailed summary of the issue, traffic sample, and any associated information you think may be useful.
