Scoping infections and disrupting breaches

Infection and exploits will occur. The new goal is to prevent those infections from becoming a data breach. To do this successfully, security analysts need the ability to continuously collect, analyze, correlate and investigate a diverse set of data. Our security expert will discuss the specific data sources and capabilities required to determine the scope of an infection before it turns into a breach. You will also see a live incident investigation that demonstrates this approach.

- 18. Demo Review Challenges – Difficult to go from threat-intel match to root cause – Hard to determine – was there a breach? Sources – Threat intel – open source threat intel feed – Network – web proxy logs, email logs – Endpoint – endpoint monitoring agent – Access/identity – asset management database Finding the root cause: connecting the dots – Match the threat-intel IP to network data to identify the infected machine – Identify the malicious process by mapping network data to endpoint data – Discover the infected email by matching local file access to email data
- 19. Best Practices—Breach Response Posture Bring in data from at least one from each category: – Network – next gen firewall or web proxy, email, DNS – Endpoint – Windows logs, registry changes, file changes – Threat intelligence – open source or subscription based – Access and identity – authentication events, machine-user mapping Establish a security intelligence platform so analysts can: – Contextualize events, analytics and alerts – Automate analysis and exploration – Share techniques and results to learn and improve

Editor's Notes
- There are three numbers in the cyber security statistics are very telling, and we should pay close attention to: 100% of breaches are done using valid credentials; And it still takes average 229 days to detect a breach; With all security technologies deployed in the enterprises, there are still 67% of , which represents 2 out 3, breaches are first reported to the enterprise by a 3rd parties (FBI, SS)
- Splunk is a Security Intelligence Platform and we can address a number of security use cases. We’re more flexible than a SIEM and can be used for non-security use cases. Splunk software can complement or replace existing SIEM deployments, while also addressing more complex security use cases, such as supporting fraud detection and finding insider threats.
- You want visibility where the adversary manifests itself. Imagine a malicious email that gives delivered. what are the places you can detect it ? And respond to the breach ? Network – network based attack, lateral movement, exfiltration Endpoint – malware exploitation – data gathering, launch point Authentication – the basis of lateral movement and access to assets, intellectual property Threat intel – External context to be fused with all these data sources, in advance of the attack or post breach You derive this rationale from the activity in your in your environment. Fusing it with the knowledge of those who have broader vantage points. And then contextualizing it with business information. Lets talk about each of these. Many of you in this room have told us that this is what works. And indeed, this has been my own experience. Before I came to splunk, I was a splunk customer…. And this strategy works… Lets dive into this…
- The capabilities required to distinguish an infection from a breach Why is it important to preserve an event?
- Risk Based Analytics to Align Security Operations With the Business Risk scoring framework enhances decision making by applying risk score to any data Quickly and easily assign any KSI or KPI to any event to produce risk scores Expose the contributing factors of a risk score for deeper insights Visualize and Discover Relationships for Faster Detection and Investigation Visually fuse data, context and threat-intel across the stack and time to discern any context Pre-built correlations, alerts and dashboards for detection, investigation and compliance Workflow actions and automated lookups enhance context building Enrich Security Analysis with Threat Intelligence Automatically apply threat intelligence from any number of providers Apply threat intelligence to event data as well as wire data Conduct historical analysis using new threat intelligence across all data
- The adversary’s success lies in a deliberate methodology. Intelligence-Driven Computer Network Defense Informed by Analysis of Adversary Campaigns and Intrusion Kill Chains
- Exploitation != Gameover when you have analysts that can use the analytics ability and contextualize it
- Use the animation to talk to the Zeus attack scenario described in the Zeus demo. Reconn – find vulnerability, find method most likely to gain access – locate vulnerable server with .pdf Reconn - Attacker attacks an extranet portal (vulnerable server) and steals a known good document (.pdf) Weaponization - Attacker creates malware and packages up in pdf and names it the same document as that on the portal (look like a good document) Delivery - Attacker spoofs (use technique to send email that looks like it’s coming from an employee of the company) a company employee email and sends to several targets at the company Exploitation – User (all it takes is one) reads email, open the attachment, exploits a vulnerable in a document reader that allows programs to run Installation – program installs several programs that over-write “good” programs on the computer – the calculator program – calc.exe Installation – calc.exe spans svchost.exe, a generic program on windows machines Command and Control – svchost.exe establishes communication to remote command and control server. Point out – this came from a real example. The left shows the different defensive technologies that might have seen something.
- Contextualization and exploration is automatic – you saw this in the field discovery menu Raw events without modification or changes – so you can auto-extract and search adhoc and tie things together as you see fit Nothing to join Create a search
- Over 2500 security/compliance customers worldwide. Customers cover all sizes and verticals, and are all over the world. While not listed here, hundreds of SMBs and individuals also use for security/compliance.
