Build A Data Lake For Your Security Logs With Scanner
Data Engineering Podcast
Indexing Strategies and Challenges
This chapter explores the different approaches to indexing variegated and semi-structured data, discussing the trade-offs between ingestion speed, query speed, and cost. The focus is on making search faster and cheaper for massive data sets, particularly in the security space, with a focus on ad hoc searching and detection queries.

Summary
Monitoring and auditing IT systems for security events requires the ability to quickly analyze massive volumes of unstructured log data. The majority of products that are available either require too much effort to structure the logs, or aren't fast enough for interactive use cases. Cliff Crosland co-founded Scanner to provide fast querying of high scale log data for security auditing. In this episode he shares the story of how it got started, how it works, and how you can get started with it.

- Your host is Tobias Macey and today I'm interviewing Cliff Crosland about Scanner, a security data lake platform for analyzing security logs and identifying issues quickly and cost-effectively
Interview
- Introduction
- How did you get involved in the area of data management?
- Can you describe what Scanner is and the story behind it?
- What were the shortcomings of other tools that are available in the ecosystem?
- What is Scanner explicitly not trying to solve for in the security space? (e.g. SIEM)
- A query engine is useless without data to analyze. What are the data acquisition paths/sources that you are designed to work with?- e.g. cloudtrail logs, app logs, etc.
- What are some of the other sources of signal for security monitoring that would be valuable to incorporate or integrate with through Scanner?
- Log data is notoriously messy, with no strictly defined format. How do you handle introspection and querying across loosely structured records that might span multiple sources and inconsistent labelling strategies?
- Can you describe the architecture of the Scanner platform?
- What were the motivating constraints that led you to your current implementation?
- How have the design and goals of the product changed since you first started working on it?
- Given the security oriented customer base that you are targeting, how do you address trust/network boundaries for compliance with regulatory/organizational policies?
- What are the personas of the end-users for Scanner?
- How has that influenced the way that you think about the query formats, APIs, user experience etc. for the prroduct?
- For teams who are working with Scanner can you describe how it fits into their workflow?
- What are the most interesting, innovative, or unexpected ways that you have seen Scanner used?
- What are the most interesting, unexpected, or challenging lessons that you have learned while working on Scanner?
- When is Scanner the wrong choice?
- What do you have planned for the future of Scanner?
