Cloud security best practices, as well as most compliance programs, require that logging be enabled for all in-scope services. However, that simple requirement — “enable logging†— comes with many followup questions. Is CloudTrail enough? How do I turn on logging for all these services? Aren’t logs collected by default? What. even. is. a. log? In AWS, logging, like most tasks, isn’t as simple as i

Product Managers and Data Scientists analyze the logs, hoping to discover actionable insights to drive product refinements. Slack’s desktop application is written in React.
