GPML: Graph Processing for Machine Learning

The dramatic increase of complex, multi-step, and rapidly evolving attacks in dynamic networks involves advanced cyber-threat detectors. The GPML Graph Processing for Machine Learning library addresses this need by transforming raw network traffic traces into graph representations, enabling...

PVS UEFI targets fail to boot when downloading TFTP bootstrap

The customer was migrating from PVS BIOS based target devices to PVS UEFI based target devices. BIOS based target devices were deprecated in PVS 2203, and all customers should be migrating to UEFI based target devices. The customer was using VMware based target devices, and was reconfiguring targ...

PVS target devices will not HA failover to another PVS server.

PVS target devices will not HA failover to another PVS server. Targets devices will freeze until the original server they were streaming from is available again. HA related configurations can be checked: The vdisk should beconfigured to use cache in ram with overflow to local device hard disk, an...

PVS PXE boot fails: No more network devices / No bootable device

PXE boot fails TFTP transfer after receiving a valid DHCP configuration. Sample failure of this type in screenshot below. Network traces show correct ARP responses going both ways. The target device will not send the first read request unless the ARP response is correct. line 13 in the screenshot...

Secure Mail Issues with Android Push Notifications

SecureMail on android devices was not getting background push notifications, therefore users had to manually open SecureMail to check for email. When examining network traces from the ADC, we observe connections to certain Google owned IP addresses are being blocked...

Protocol Learning and Stateful Fuzzing: Pulsar

Pulsar is a network fuzzer with automatic protocol learning and simulation capabilites. The tool allows to model a protocol through machine learning techniques, such as clustering and hidden Markov models. These models can be used to simulate communication between Pulsar and a real client or serv...
