## Concept
  **LogonTracer** is a tool to investigate malicious logon by visualizing and analyzing Windows Active Directory event logs. This tool associates a host name (or an IP address) and account name found in logon-related events and displays it as a graph. This way, it is possible to see in which account login attempt occurs and which host is used.  
  This tool can visualize the following event id related to Windows logon based on [this research](https://www.first.org/resources/papers/conf2016/FIRST-2016-105.pdf).  
  * **4624**: Successful logon  
  * **4625**: Logon failure  
  * **4768**: Kerberos Authentication (TGT Request)  
  * **4769**: Kerberos Service Ticket (ST Request)  
  * **4776**: NTLM Authentication  
  * **4672**: Assign special privileges

## Additional Analysis
  LogonTracer uses [PageRank](https://en.wikipedia.org/wiki/PageRank), [Hidden Markov model](https://en.wikipedia.org/wiki/Hidden_Markov_model) and [ChangeFinder](https://pdfs.semanticscholar.org/c5bc/7ca31914d3cdfe1b2932cbc779875e645bbb.pdf) to detect malicious hosts and accounts from event log.

  With LogonTracer, it is also possible to display event logs in a chronological order.

## Architecture
  LogonTracer is written in Python and uses Neo4j for database. The following tools are used.  

  * Python 3
  * [Neo4j](https://neo4j.com) for a graph database.  
  * [Neo4j JavaScript driver](https://github.com/neo4j/neo4j-javascript-driver) for connects to Neo4j using the binary protocol.  
  * [Cytoscape](http://www.cytoscape.org/) for visualizing a graph network.
  * [Flask](http://flask.pocoo.org/) is a microframework for Python.
