## Overall
+ Removed the Init files dependencies on all containers
+ Added more resources to the resources folder (papers and presentations)
+ Updated to-do list on main README
+ Removed Static Network setting. Addressing overlapping network issues (https://github.com/Cyb3rWard0g/HELK/issues/43)
+ Updated WIki and added new images to it
+ Started documenting potential error messages or bugs with a few quick fixes
## Helk Install Script
+ Script now collects information about Available Memory and Disk size for LINUX host ONLY. it only continues if the box hosting the HELK has at least 12GB of RAM and 50GB of Disk Available. (This can be overwritten manually by just editing the helk_install script before installing the HELK)
## ELK Stack
+ Started using Elastic Docker Images as a base
+ Updated ELK stack to 6.2.4 version
+ X-Pack Basic Free License attached to build automatically
+ Monitoring capabilities are now enabled in the build (Reason why Cerebro went away)
## Spark
+ Integrated Spark Standalone Cluster Manager
+ Spark Node running with Jupyter Notebook now points to the Helk-Spark-Master container for any execution of code
+ Added Spark Master and Worker Docker Images
+ Build runs now with 2 Workers and 1 Master by default.
+ Apache Arrow is enabled for Pandas Dataframe optimization
+ Created Spark-Base Docker Image (Applied to the Jupyter Image)
## Kafka
+ Kafka Container was split in Kafka Brokers and one Zookeeper
+ Helk runs with 2 Kafka Brokers and 1 Zookeeper by default
## Jupyter Container
+ Preparing to add Zeppelin Notebook. the Analytics container is now named Jupyter. It uses the Spark-Base image to build on the top and install the necessary packagess
+ New packages were added:
++ nxviz
++ hiveplot
++ pyarrow
+ Apache Arrow is not enabled on the Jupyter node to be able to optimize the use of Pandas DataFrames
Removed OTX Enrichment for now to reduce the load on logstash and keep it clean for now. It will be added in the future. Implementation is already developed.

+ Fingerprint plugin in logstash config 09-all-filter.con is applied to only events with the message field.
+ logstash config 11-winevent-sysmon-filter.conf

++ Check kafka release notes:
https://www.apache.org/dist/kafka/1.0.1/RELEASE_NOTES.html
+ Removed sleep time for kafka init file

HELK helk_install main script
+ Fixed docker & docker-compose installation steps. This fixes issue https://github.com/Cyb3rWard0g/HELK/issues/33
HELK Winlogbeat install script
+ Updated beat version to 6.2.3
helk-analytics
+ Init file and Dockerfile updated with Spark version 2.3.0
+Jupyter Notebook from getting started folder updated
+ New jupyter notebook with graphframes example presented in BSColumbus 2018
helk-elk

Resources:
- Created README to share all the blog posts, documentes and presentations that helped me to work on the HELK
Scripts
+ Deprecated most of the scripts used before to install ELK via TAR and DEB. Also deprecated scripts to updated geoip database.
HELK Design
+ moved everything to docker-compose approach for a more modular design.
+ separated the HELK in 3 services:
++helk-elk, helk-kafka, helk-analytics
+ Updated Design picture to show WEF ideas and also show Jupyter Lab integrations.
HELK Docker-Compose
+ Added ESDATA volume to keep logs after contaners get stopped
+ Services restart automatically after reboot
+ created blank env file for Kafka service. This allows the host to pass its own local IP to Kafka. This is needed for advertised listener configs on each broker.
HELK-ELK Version
- Updated to 6.2.2
ELasticsearch
- Added local docker network as part of the network.host option. This allows the HELK-ELK service to publish its docker local IP to other services/images in the docker compose environment.
Logstash

Kibana
+ enableExternalUrls set to true for Vega visualization that need external libraries.

Logstash
+ Adjusted Batch size to 300 (Testing)
+ Renamed scripts to follow a standard naming convention
+ Added a fingerprint filter to all logs to help reduce duplicate logs
+ Removed ELK Version strings from all Logstash configs so that I dont have to update every single script every time ELK gets updated.
+ Added Document_id to every logstash output config to take the fingerprint value.
Kibana
+ Renamed Index Patterns to standard naming convention.
+ Added experimental visualization vega setting. Enabling External URLs to use D3 libraries from their repos. This is grayed out in the Kibana config so user will have to enable it.
+ Updated name of index patterns across all visualizations and dashboards.
Kafka
+ Log retention is now 24 hours and not 268 Hours
+ added auto_offset_reset => "earliest" to beats kafka input config
Spark
+ updated es-hadoop version to 6.2.0 and added new spark jar packages: org.apache.spark:spark-sql-kafka-0-10_2.11:2.2.1 & databricks:spark-sklearn:0.2.3
+ Created an init file to run spark and jupyter all together as a service. This will allow us to restart jupyter and pyspark gracefully.
Winlogbeat
+ Updated Winlogbeat config to take PowerShell and Microsoft-Windows-WMI-Activity/Operational logs.
