The document discusses building an analytics-driven security operations center (SOC) using Splunk. It begins with an overview of challenges with traditional SOCs, such as efficacy, staffing, siloization, and costs. It then covers trends in security operations like increased capabilities, automation, use of threat intelligence, and threat hunting. The document outlines components of the security operations toolchain including the log data platform, asset inventory, case management, and common data sources. It presents Splunk as a nerve center for security operations that can provide adaptive security architecture, threat intelligence framework, advanced analytics, automated processes, and proactive hunting and investigation. Finally, it shares examples of how customers have used Splunk to build intelligence-driven SO

- 28. 28 Automation in the SOC • Response – maybe • Context gathering – definitely • Automate “Tier 1” • Places a high premium on toolchain integration
- 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
- 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?)
- 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 Case and Investigation Management • Ticketing system • Workflow • Supports prioritization • Supports collaborative investigation • Provides metrics • Supports automation • Auditable
- 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
- 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

- 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 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 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 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
