Bsides Calgary 2017 Instructions for Running the Demo BSides Calgary 2017 Title: Using Netflow & Open Source Tools for Network Behavioral Analysis Presenter: Yves B. Desharnais, MBA, CISSP, PCIP Instructions for running the demo. The demo was done under CentOS 7, but the solution was also tested under Ubuntu so most instructions should work on most Linux systems (and potentially other OSes). 1) Install OS 2) Install Fluentd (instructions: https://docs.fluentd.org/v0.12/categories/installation) a) Generally as regular user (I remember having issues installing as root) 3) Install other required packages a) The default NetFlow plugin, unless using my plugin i) sudo /opt/td-agent/embedded/bin/fluent-gem install fluent-plugin-netflow b) The MariaDB / MySQL package i) Dependencies (needs to recompile code) (1) sudo yum install gcc mysql-devel ruby-devel rubygems mariadb-server c) Secure mysql i) sudo mysql_secure_installation d) Install the fluentd mysql plugin i) sudo /opt/td-agent/embedded/bin/fluent-gem install fluent-plugin-mysql-prepared- statement e) Enable/start MySQL (now MariaDB) daemon i) systemctl enable mariadb ii) systemctl start mariadb f) Allow firewall traffic through local firewall (IPTables, firewalld, etc.) 4) Install demo code a) As root, from the unzipped archive folder: i) mv /etc/td-agent/td-agent.conf mv /etc/td-agent/td-agent.back ii) cp –R etc/td-agent/* /etc/td-agent/ iii) chmod -R 740 /etc/td-agent b) For demo 8, we need to create the databases and users (I would recommend changing the passwords…) i) mysql –u root –p < demo8.sql c) For demo 9, we need to: i) Create the database and user: mysql –u root –p < demo9.sql ii) Create the file structure for our interprocess communications (1) cp -R logmon / (2) chmod -R 775 /logmon iii) setup the cron jobs, adding line to “crontab –e”, for example: (1) 0 0 * * * * /logmon/cron/ping/sweep.sh # Daily at midnight (2) */5 * * * * /logmon/cron/nmap/nmapcronq.sh # Every 5 minutes d) edit the /etc/td-agent/td-agent.conf and to select the right demo include file e) run the service i) sudo service td-agent start (or restart) .

Espoo 3.7.2018 Supervisor Prof. Jukka Suomela Advisor MSc Cyril de Vaumas Copyright ⃝c 2018 Antti Vainio Aalto University, P.O. BOX 11000, 00076 AALTO www.aalto.fi Abstract of the master’s thesis Author Antti Vainio Title Implementation of Centralized Logging and Log Analysis in Cloud Transition Degree programme Computer, Communication and Information Sciences Major Computer Science Code of major SCI3042 Supervisor Prof. Jukka Suomela Advisor MSc Cyril de Vaumas Date 3.7.2018 Number of pages 84 Language English Abstract Centralized logging can be used to collect log data from multiple log files on multiple separate server machines and transmit the data to a single centralized location. Log analysis on top of that can automatically process large amounts of logs for various different purposes including problem detection, troubleshooting, monitoring system performance, identifying security incidents, and understanding user behavior. As the volume of log data is growing when software systems, networks, and services grow in size, the log data located on multiple separate server machines can be difficult to manage. The traditional way of manually inspecting logs hasalso become too labor-intensive and error-prone when large amounts of log data need to be analyzed. Setting up centralized logging and automatic log analysis systems can be used to solve this problem. This thesis explains the concepts of log data, centralized logging, and log analysis, and also takes a look at existing software solutions to implement such a system.

  • Using Fluentd As an Alternative to Splunk
    Using Fluentd as an alternative to Splunk As infrastructure within organizations grows in size and the number of hosts, the cost of Splunk may become prohibitive. I created this document to demonstrate, step-by-step, how to implement Fluentd, Elasticsearch and Kibana to be used as a replacement for Splunk. This is a simple configuration and does not include clustering. I may add clustering in later versions. The OS used for this configuration is CentOS 6.7. The instructions for newer versions of CentOS/RHEL, and for Ubuntu may vary. All commands should be run as root or be preceded by “sudo “. © 2015 William C.

  • Analysis and Comparison of Log Shipment Solutions at AWS S3 for Windows 10
    Department of Information Engineering and Computer Science Master in Computer Science 2020-2021 Final thesis Analysis and comparison of Log Shipment solutions at AWS S3 for Windows 10. Francisco Manuel Colmenar Lamas i SUMMARY A fundamental aspect that every company must address to start building its security infrastructure is visibil- ity. Increasing a company’s visibility raises the quality and effectiveness of all other existing security solutions. The objective was to implement an endpoint log forwarding solution for the Windows 10 devices of the com- pany About You. To accomplish the objective, several concepts and knowledge in the scope of log management solutions were studied, as well as the use of AmazonWeb Services (AWS) dedicated to these activities. After analyzing the different solutions, Kinesis Windows Agent was chosen to implement the endpoint log shipment solution. Because it provides a serverless architecture, where the agent sends logs from the endpoints to Kinesis Firehose. In addition, it does not require any heavy-weight dependencies and its configuration is straightforward. Also, since Kinesis Firehose is an AWS managed service, there is no need to handle the scaling or fault tolerance issues common in a client-server architecture and it integrates seamlessly with S3. Regarding the implementation, the code for the installation and maintenance of the Kinesis Windows Agent was mainly developed in Powershell scripts triggered remotely using Ninjarmm. And the AWS infrastructure code required for this project was developed using Terraform. In addition, through Gitlab’s CI/CD pipeline, AWS resources are automatically updated if the code is modified. As a conclusion, the deployment of the Kinesis agent for Windows on all employee Windows devices was a success.

    Welcome to Linux Foundation E-Learning Training 2021/09/17 Version 8.31 Copyright © 2010-2021 The Linux Foundation. All rights reserved. If you have any further questions after reading this document, the answer may be found in the FAQ on the website: http://bit.ly/LF-FAQ or https://training.linuxfoundation.org/about/faqs/general-faq/ Specific instructions for your course will be addressed in the Appendix. Contents 1 Hardware Requirements 1 2 Software Requirements 2 Appendices 4 A Course-Specific Hardware and/or Software Requirements 4 B More Details on Installing Linux 18 1 Hardware Requirements Students are expected to provide their own computers for Linux Foundation courses. The following instructions should make clear the specifics that apply to you. All courses have slightly different HW requirements. Specific HW requirements for your class can be found in the Appendix. The Linux Foundation logistical staff may be consulted as required for further clarification. 1.1 Using a Virtual Machine Instead Virtual Machines If you elect to use a Virtual Machine (instead of native Linux) bear in mind that the hard- ware requirements double, since you now need enough CPU/RAM for the host operating system as well as the guest OS. Using a VM for this course can make things faster/easier; if you make a fatal mistake, a simple reboot of the VM will restore things to normal. More on what distro and software needs to be installed on the VM can be found in the Software Requirements chapter below. 1 1.2 Pre-Built Virtual Machine Images 2 If you want to build your own VM image You can make sure your own Virtual Machine image is properly setup for the class using the ready-for.sh script which can be found as follows: http://bit.ly/LFprep or https://training.linuxfoundation.org/cm/prep/ 1.2 Pre-Built Virtual Machine Images We provide pre-built virtual machine images that work with VMware products (e.g.
