Security Analytics At the Speed of Thought With ML and Elastic

Abstract: This talk was a continuation of the discussion started in February where we will overview how machine learning in Elastic X-Pack can be used to analyze data from a data lake help the SOC (Security Operations Center) and Threat Hunting teams find malicious actors in their environment. We will demonstrate how easy it is to pivot through data and start to expand the information we have around the compromise.

Geoff presented a demo similar to this one,

May 23, 2018, was a great day! Thank you, all.

Searching Blockchain with FreeEed

The Blockchain is composed of multiple blocks that can contain any information. However, it is not a database in a traditional sense: it is not fast, and it does not answer queries.

For example, the writing speed is one block every 10 minutes for Bitcoin and about one block every seven seconds for Ethereum. Queries, as such, do not exist at all: neither SQL nor NoSQL-type language is not provided.

Meanwhile, the information stored in Blockchain often needs to be searched. Here is a design pattern from CSIRO.

As of today, such a tool exists. FreeEed has been used by lawyers to do eDiscovery, legal reviewers, and researchers for all kinds of investigations. It allows you to give any data as input (see here) and indexes that data for searches. The data can be open Office files, PST mailboxes, a "load file" produced to lawyers due to an eDiscovery request, and Blockchain.

We are actively working on FreeEed all the time, adding input formats, processing capabilities, and machine learning. The tool is open source and welcomes new additions. The review part is called "FreeEed Review" and works through the browser.

The back end used to implement text search is Elasticsearch. This means that you can also look at the processed data through the mighty ELK (Elasticsearch, Logstash, Kibana), which is also open source.

Happy searching!
