  35. 35. 35 How are SOC Teams Hunting? https://www.sans.org/reading-room/whitepapers/analyst/who-what-where-when-effective-threat-hunting-36785 ● Start with a hypothesis that considers: § Assets (often crown jewels) § Threats § Vulnerabilities § Countermeasures ● Requires lots of data ● Flexible platform to ask/answer questions ● Data science / ML / Analytics
  36. 36. 36 How are SOC Teams Hunting? https://www.sans.org/reading-room/whitepapers/analyst/who-what-where-when-effective-threat-hunting-36785 Most important, hunters are innovative analysts who understand their threat landscape and their organization well enough to ask the right questions and find the answers.
  37. 37. 37 Data Science, ML, and Analytics
  38. 38. The Security Operations Toolchain
  39. 39. 39 Log Data Platform • Single source of truth • Retention and integrity • Any data source • Easy correlation • Automation / integration • Performant and scalable • Full fidelity • Normalized? • Hunting • Forensic investigation • Alerting • Dashboards • Visualization • Analytics (ML?)
  40. 40. Data Normalization is Mandatory for your SOC “The organization consuming the data must develop and consistently use a standard format for log normalization.” – Jeff Bollinger et. al., Cisco CSIRT Your fields don’t match? Good luck creating investigative queries
  41. 41. 41 Asset Inventory and Identity Data Often multiple sources of record – that’s OK • CMDB, Vuln scans, Passive detection, DHCP, NAC • Active directory, LDAP, IAM Network diagrams Categorization • PCI, ICS, Administrative, Default, Comprehensive yet lightweight and easy to maintain Must be easy to correlate to log data
  42. 42. 42 Case and Investigation Management • Ticketing system • Workflow • Supports prioritization • Supports collaborative investigation • Provides metrics • Supports automation • Auditable
  43. 43. 43 Common SOC Data Sources • Firewall • Network metadata • Authentication • Server • Windows / Linux • Endpoint • EDR, AV, HD/RAM images • IDS / IPS • VPN • Application • Threat intel • Vulnerability • Assets and Identities

  45. 45. 45 Splunk as the Security Operations Nerve Center
  46. 46. 46 1. Adopt an Adaptive Security Architecture To Prevent, Detect, Respond and Predict need: - Correlation across all security relevant data - Insights from existing security architectures - Advanced analytics techniques such as machine learning Platform for Operational Intelligence 4000+ Apps and Add-Ons Splunk Security Solutions
  47. 47. 47 2. Threat Intelligence – Splunk Threat Intel Framework Automatically collect, aggregate and de-duplicate threat feeds from a broad set of sources Support for STIX/TAXII, OpenIOC, Facebook and more Build your own data to create your own Threat Intel Out of the box Activity and Artifact dashboards Prioritize, contextualize and analyze threats and remediate Law Enforcement Feeds ISAC Feed Agency Feeds Commercial Service Community Feed Open-Source Feed Other Enrichment Services • Monitor and triage alerts • Determine impact on network, assets • Use for analysis / IR • Collect / provide forensics • Use to hunt / uncover /link events • Share info with partners
  48. 48. 48 3. Use Advanced Analytics – Native ML and UBA Simplify detection and focus on real alerts Accelerate anomaly and threat detection – minimize attacks and insider threat Use Machine Learning toolkit - solutions to suit your workflow Premium Machine learning solution - User Behavior Analytics – Flexible workflows for SOC Manager, SOC analyst and Hunter/Investigator within SIEM
  49. 49. 49 4. Proactively Hunt and Investigate - Considerations ● Organizational maturity ● Domain and product experience ● Tools: Network, Endpoint, Threat Intel, Access ● Security relevant data, historical, raw data ● Flexibility and ad hoc
  50. 50. 50 5. Automate whenever feasible App Servers Network Threat Intelligence Firewall Internal Network Security Endpoints Use rules and machine learning to automate routine aspects of detection and investigation Extract insights from existing security stack by use of common interface Take actions with confidence for faster decisions and response Automate any process along the continuous monitoring, response & analytics cycle Splunk Adaptive Response

  53. 53. Customer Success
  54. 54. 54 Building an Intelligence Driven SOC Challenges • Existing SIEM not adequate - struggled to bring in appropriate data • Unable to perform advanced investigations, severe scale/performance issues • Looking to build a new SOC with modern solution Customer Solution • Centralized logging of all required machine data at scale and full visibility • Retain all relevant data from 10+ data sources which is used by 25+ SOC/CSIRT users • Tailored advanced correlation searches & IR workflow • Faster and deeper incident investigations • Greater SOC efficiencies - all SOC/CSIRT working off same UI/data • Executive dashboards to measure and manage risk 54
  55. 55. 55 Citywide SOC for situational awareness Challenges • Slow responses to security incidents • Inadequate situational awareness of security events • Limited threat intelligence • Disparate logs from over 40 departments were difficult to aggregate Customer Solution : Splunk Cloud with Enterprise Security • Real-time, citywide, 24/7 network surveillance • Stronger protection of digital assets and infrastructure • Shared threat intelligence with federal agencies • Reduced headcount and lower operational costs
  56. 56. 56 Build an insourced SOC in months Challenges • Wide range of security requirements – Internal audits (financial, PCI) – Protect internal info and assets – Cloud firewall, DDOS • Cultural and Organizational – Security not a priority, Outsourced SecOps – Information hoarding and data silos Customer Solution : Splunk Enterprise Security • Changed culture - security first mindset with controls • Detect, prevent and respond to attacks in own environment, with 24/7 security analysis of customers • Rapid detection and deep investigation • Detect Web App attacks, discover compromised cards
  57. 57. 57 Maturing SOC Challenges • Legacy SIEM : Unstable, Inflexible, Clunky • Limited skilled resources • High false negative and false positive Customer Solution : Splunk Cloud with Enterprise Security • Developed processes : Rule set, naming • SOC process : Playbook, training, automated documentation • Enabled SOC to identify patterns of behavior in a single event rather than be bombarded by thousands of low-value incidents
