Creating a Logging Infrastructure

Logs are an essential aspect of understanding what is occurring in a company's network infrastructure and a company's applications. Log events help analysts to understand the health of the network and give insight into many types of issues. This paper explains how to set up a logging infrastructure by covering log formats and data sources. Then the discussion includes different ways to collect logs and transmit them. This paper then goes over how to pick relevant log sources and events to enable for collection. A company-wide architecture describes the process of collecting logs from offices across the world. Once the company-wide architecture is set up, the paper goes over some correlations using data from a real production network. The paper finishes by reviewing tools that are used to process, index, and correlate all the events that are received.
