Visualize AWS VPC Flow Logs in Squey using Apache Parquet format
Visualize AWS VPC Flow Logs in Squey using Apache Parquet format
Since version 5.0, Squey is able to import and export Apache Parquet files! « Apache Parquet is an open-source file format that stores data efficiently in columnar format, provides different encoding types, and supports predicate filtering. With good compression ratios and efficient encoding, VPC flow logs stored in Parquet reduce your Amazon S3 storage costs. » ― AWS Blog Let’s take advantage of the fact that AWS VPC Flow Logs can be natively stored in Apache Parquet format to seamlessly visualize our network and understand traffic patterns, identify security issues, audit usage, and diagnose network connectivity.

DFIR MONTEREY 2015 Network Forensics Challenge
DFIR MONTEREY 2015 Network Forensics Challenge
This article aims at solving the PCAP related questions from the DFIR MONTEREY 2015 Network Forensics Challenge using Squey. Of course the idea here is not to really solve the challenge as it has been solved numerous times since then, but to see how easier it is to solve it using Squey. The dataset 2014-11+DFIR+Network+Forensics+Challenge.zip was taken from the Netresec PCAP page. Note: questions 1 and 4 were not solved because they didn’t involve any PCAP data.
