Using Netflow & Open Source Tools for Network Behavioral Analysis
 
43:36
Yves Desharnais will explain what the Netflow protocol is, how it works, and how to use open source tools (fluentd, nmap, etc.) to parse this data flow information and create a comparison engine that will match network traffic to defined rules. This approach was used successfully to reduce PCI DSS server scope size to under 20% in mid-2016 on a medium-sized network, and to apply firewall rules live without any business disruption.

Want to get started on a hunt team and discover "bad things" on your network? In this webcast, we will walk through the installation and usage of Real Intelligence Threat Analytics (RITA). RITA is an open-source framework from the folks at Black Hills Information Security and Offensive CounterMeasures. RITA ingests Bro logs and seeks out malicious payload beaconing and scanning behavior. It also determines which systems in your environment are talking with known bad IP addresses and domains. In less than an hour, you will learn how to collect and analyze network traffic for hunt teaming analysis. We will also provide some sample Bro logs for you to play with and give RITA a test drive. Want to use your own Bro logs? Great! Just make sure your logs come from an egress pre-NAT point where we can see the internal RFC 1918 IP addresses talking to external IP addresses. We'll cover the different types of math used in our analysis, including: - Connection intervals - Data sizes - Connection times As a bonus, our sponsor, LogRhythm, will be showing off a completely free network monitoring tool called Network Monitor Freemium — a free tool for network monitoring, application detection, and detecting suspicious network activity (including lateral movement)!

If you're like me, you probably have terabytes of PCAP files filling up your hard drive.  In previous articles I have reviewed one of my favorite "big trace file" tools Packet Analyzer from Riverbed.  I absolutely love using this tool for quickly searching through a big trace looking for that needle in the haystack. What happens when you have 100s of haystacks (PCAP files) and you still want to find that needle?   In this short video we will look at a way to take that hard drive full of PCAPs, index them, and allow you to very quickly sort through terabytes of data.    Questions?

Why It’s Time to Make Network Traffic Analysis A First-Class Citizen
 
59:53
Since nearly all cyberattacks must cross the network it’s an essential source of truth for threat hunters and incident responders, yet many organizations today have limited network traffic analysis capabilities. Why? The root of the problem lies in common sources of network data, which are difficult to analyze at scale. Security operators often find themselves stuck between the unwieldy firehose of full traffic capture and the frustrating information desert of network logs like Netflow that offer only a minimal amount of detail. Simply put, it’s either too much, or too little network data. A goldilocks alternative exists, however, in the Bro Network Security Monitor. This open source framework transforms network traffic into high-fidelity logs that summarize activity on the wire at less than 1% the size of full traffic capture and can automate traffic analysis tasks via Bro’s unique scripting language. Thousands of organizations rely on Bro to achieve comprehensive, scalable network traffic analysis and Corelight makes Bro easy and ready to deploy at enterprise scale. In this webinar, Eric Ogren, Senior Analyst at 451 Research, and Brian Dye, CPO at Corelight, will demonstrate how Bro can help organizations achieve comprehensive, scalable network traffic analysis and accelerate their threat hunting and incident response workflows.

DEFCON 16: Malware Detection through Network Flow Analysis
 
50:29
Speaker: Bruce Potter, Founder, The Shmoo Group Over the last several years, we've seen a decrease in effectiveness of "classical" security tools. The nature of the present day attacks is very different from what the security community has been used to in the past. Rather than wide-spread worms and viruses that cause general havoc, attackers are directly targeting their victims in order to achieve monetary or military gain. These attacks are blowing right past firewalls and anti-virus and placing malware deep in the enterprise. Ideally, we could fix this problem at its roots; fixing the software that is making us vulnerable. Unfortunately that's going to take a while, and in the interim security engineers and operators need new, advanced tools that allow deeper visibility into systems and networks while being easy and efficient to use. This talk will focus on using network flows to detect advanced malware. Network flows, made popular by Cisco's NetFlow implementation available on almost all their routers, has been used for years for network engineering purposes. And while there has been some capability for security analysis against these flows, there has been little interest until recently. This talk will describe NetFlow and how to implement it in your network. It will also examine advanced statistical analysis techniques that make finding malware and attackers easier. I will release a new version of Psyche, an open source flow analysis tool, and show specific examples of how to detect malware on live networks. I will also release a tool designed to craft and spoof netflow records for injection into netflow collectors.

Bart van der Sloot and Samer Abdel-Hafez (FiberRing): "FiberRing operates one of the largest content networks in the world, peaking at over 2 Tb/s. In order to facilitate troubleshooting, detect attacks and saving important data as router configurations, we implement a series of tools mostly implemented in house or open source. The key point of this presentation is to describe how FiberRing is using these tools for: monitoring: FiberRing makes extensive use of Opsview (Nagios) and NMIS. We utilise Opsview for alerts and reporting and NMIS for detailed traffic analysis. capacity planning: FiberRing choose PMACCT as netflow collector software and implemented an in house front-end solution that helps us locate strategic peering partners and explore ways to reduce the costs to deliver our content. DDOS attacks detection: As every large hosting provider, we are regularly target of DDoS attacks. We implement a set of linux boxes running running nfcapd to collect traffic flows with 1 minute/per host granularity. This gives us great flexibility and incredibly valuable data to quick detect attacks and take corrective actions. routers’ configuration backups: FiberRing is actively involved in the development of Oxidized, an innovative configuration backup tool which poses itself as rancid replacement".

Open Source Malware Lab - Robert Simmons
 
49:41
The landscape of open source malware analysis tools improves every day. A malware analysis lab can be thought of as a set of entry points into a tool chain. The main entry points are a file, a URL, a network traffic capture, and a memory image. This talk is an examination of the major open source tools that satisfy the analysis requirements for each of these entry points. Each tool’s output can potentially feed into another tool for further analysis. The linking of one tool to the next in a tool chain allows one to build a comprehensive automated malware analysis lab using open source software. For file analysis, the three major versions of Cuckoo Sandbox will be examined. To analyze a potentially malicious URL, the low-interaction honeyclient, Thug, will be covered. Next, if one has a network capture (PCAP) to analyze, the Bro Network Security Monitor is a great option, and will be covered. Finally, if the analysis target is a memory image, the Volatility Framework will be examined. Each of the inputs and outputs of the tools will be reviewed to expose ways that they can be chained together for the purpose of automation.

Network Traffic Analysis of Hadoop Clusters Understand the common usage patterns and identify typic…
 
29:07
Network Traffic Analysis of Hadoop Clusters Understand the common usage patterns and identify typical / atypical workloads. by Mirko Kämpf At: FOSDEM 2017 Cybersecurity is a broad topic and many commercial products are related to it.We demonstrate a fundamental concept in network analysis: re-construction andvisualization of temporal networks. Furthermore, we apply the method todescribe operational conditions of a Hadoop cluster. Our experiments providefirst results and allow a classification of the cluster state related tocurrent workloads. The temporal networks show significant differences fordifferent operation modes. In reallity we would expect mixed workloads. Ifsuch workload parameters are known, we are able to handle a-typical eventsaccordingly - which means, we are able to create alerts based on contextinformation, rather than only the package content. We show an end-to-endexample: (1) Data collection is done via python, using the sniffer script; (2)using Apache Hive and Apache Spark we analyze the network traffic data andcreate the temporary network. Finally, we are able to visualize the resultsusing Gephi in step (3). In a next step, we plan to contribute to the ApacheSpot project. # Expected prior knowledge / intended audience: No special skills required, but minimal exposure to the Hadoop ecosystem ishelpful. # Speaker bio: Márton Balassi is a Solution Architect at Cloudera and a PMC member at ApacheFlink.

Another cool thing about open-source Bro: SMB analysis!
 
05:38
You may know that Bro can uncover indicators of compromise and discover adversary lateral movement by monitoring east-west traffic within the enterprise. But you may not know about one of the best sources of data for this purpose, the Bro server message block (SMB) logs. Bro’s SMB protocol analyzer has undergone several iterations, and it is now a built-in feature that many Bro users might have overlooked. If you are running Bro 2.5, all that is needed is to manually load the SMB policy. SMB is used for many purposes. Most users of Windows networks rely on SMB every day when accessing files on network drives, and network administrators use the same protocol when they perform remote administration. Unfortunately the adversary, whether script kiddies or nation-state actors, also uses SMB! By the way, do you know whether SMBv1 is running on your network… and how can you be sure? This video provides an introduction to the power of Corelight’s advanced filtering and the content contained in Bro’s SMB logs to monitor SMB usage for remote scheduled tasks and file access. If you use Bro to monitor SMB, please share tips here so others can benefit – if you don’t use Bro, learn how it transforms raw network traffic into comprehensive, organized logs. If you are interested in learning more detail about Bro’s ability to detect malicious activity hidden in SMB, this SANS paper is a great place to start.

This paper was presented by Robert Simmons (ThreatConnect) at VB2016 in Denver, CO, USA. The landscape of open source malware analysis tools improves every day. A malware analysis lab can be thought of as a set of entry points into a tool chain. The main entry points are a file, a URL, a network traffic capture, and a memory image. This talk is an examination of the major open source tools that satisfy the analysis requirements for each of these entry points. Each tool's output can potentially feed into another tool for further analysis. The linking of one tool to the next in a tool chain allows one to build a comprehensive automated malware analysis lab using open source software. For file analysis, the three major versions of Cuckoo Sandbox will be examined. To analyse a potentially malicious URL, the low-interaction honeyclient, Thug, will be covered. Next, if one has a network capture (PCAP) to analyse, the Bro Network Security Monitor is a great option, and will be covered. Finally, if the analysis target is a memory image, the Volatility Framework will be examined. Each of the inputs and outputs of the tools will be reviewed to expose ways in which they can be chained together for the purpose of automation. https://www.virusbulletin.com/conference/vb2016/abstracts/open-source-malware-lab

Defocon 16 - Malware Detection through Network Flow Analysis
 
50:29
This video is part of the Infosec Video Collection at SecurityTube.net: http://www.securitytube.net Defocon 16 - Malware Detection through Network Flow Analysis https://www.defcon.org/images/defcon-16/dc16-presentations/defcon-16-potter.pdf Over the last several years, we've seen a decrease in effectiveness of classical security tools. The nature of the present day attacks is very different from what the security community has been used to in the past. Rather than wide-spread worms and viruses that cause general havoc, attackers are directly targeting their victims in order to achieve monetary or military gain. These attacks are blowing right past firewalls and anti-virus and placing malware deep in the enterprise. Ideally, we could fix this problem at its roots; fixing the software that is making us vulnerable. Unfortunately that's going to take a while, and in the interim security engineers and operators need new, advanced tools that allow deeper visibility into systems and networks while being easy and efficient to use. This talk will focus on using network flows to detect advanced malware. Network flows, made popular by Cisco's NetFlow implementation available on almost all their routers, has been used for years for network engineering purposes. And while there has been some capability for security analysis against these flows, there has been little interest until recently. This talk will describe NetFlow and how to implement it in your network. It will also examine advanced statistical analysis techniques that make finding malware and attackers easier. I will release a new version of Psyche, an open source flow analysis tool, and show specific examples of how to detect malware on live networks. I will also release a tool designed to craft and spoof netflow records for injection into netflow collectors.

Understanding Encrypted Traffic Using "Joy" for Monitoring and Forensics
 
37:30
A classroom session from the DevNet Zone at Cisco Live Berlin 2017. The ""Joy"" open source package can track network flows and report on data features beyond those in Netflow, such as the distribution of bytes, the entropy, and the sequence of packet lengths and arrival times, as well as detailed information from TLS headers. With this data, we can better detect and understand encrypted traffic. This approach is valuable for detecting and analyzing malicious traffic, and for auditing the quality of the cryptography used to secure critical applications and communications. This session covers the Joy package, the data features that it can capture and the JSON format in which it reports data, and several use cases involving packet forensics and network monitoring. Join DevNet today! It's free, easy, and gives you access to useful resources and tools. Come learn, code, inspire, and connect. https://developer.cisco.com/site/devnet/overview/index.gsp

Getting started with Net2Plan: Time-Varying Traffic Simulation tool
 
14:32
This post-analysis tool simulates the network operation, where traffic demand volumes vary with time according to a user-defined pattern. It is targeted to evaluate the performances of built-in or user-defined schemes that react to traffic variations (i.e. traffic rerouting schemes, on-demand capacity-provisioning schemes, etc.). Here, collected statistics are referred to the average network state during the simulation (link capacities, utilization, protection degrees...). This video helps to use this tool, and explains the user interface. More information about this and other tools can be found visiting www.net2plan.com
