In this series about the characteristics of an analytics-driven security operations center (SOC), we have already discussed an adaptive security architecture. Next we will discuss what it means for an analytics-driven SOC to adopt threat intelligence capabilities.
...evidence-based knowledge, including context, mechanisms, indicators, implications and actionable advice, about an existing or emerging menace or hazard to assets that can be used to inform decisions regarding the subject's response to that menace or hazard.
Splunk Enterprise Security (ES) is a security information and event management (SIEM) solution that helps SOC teams gain insights to quickly detect and respond to internal and external attacks, while simplifying threat management, minimizing risk, adding organization-wide visibility and security intelligence for continuous monitoring, incident response and SOC operations. Splunk ES also helps SOC operations teams map to the five essential capabilities defined by Gartner.
Splunk ES maps directly to these capabilities with its Threat Intelligence framework, which consumes and manages threat feeds, detects threats and alerts. The framework consists of modular inputs that collect and sanitize threat intelligence data and lookup-generation searches, to reduce data for optimized performance. Searches correlate data and alert on the results, and data modeling accelerates and stores results. The framework also includes a number of audit dashboards that enable introspection into threat intelligence retrieval, normalization, persistence and analysis.
City of Los Angeles Integrates Real-Time Security Intelligence Sharing Across 40+ City Agencies
The City of Los Angeles uses Splunk ES and Splunk Cloud to protect its digital infrastructure, providing situational awareness of its security posture and threat intelligence for its departments and stakeholders.

In the past, the city’s more than 40 agencies had disparate security measures, complicating the consolidation and analysis of data. Los Angeles wanted a scalable SaaS SIEM solution to identify, prioritize and mitigate threats, gain visibility into suspicious activities and assess citywide risks. Since deploying Splunk Cloud and Splunk ES, the city has seen benefits including:
- Creation of citywide security operations center (SOC)
- Real-time insight into threats
- Reduced operational costs
Los Angeles uses its integrated SOC for more than collecting information. In fact, the city’s analytics-driven SOC actually provides information. It translates data from Splunk Cloud into timely threat intelligence, which the city shares with its agencies as well as external stakeholders like the FBI, the Department of Homeland Security, the Secret Service and other law enforcement agencies. With this information, the city collaborates with federal agencies to identify risks and develop strategies for deterring future network intrusions. Want to know more about the City of Los Angeles?
