SIEM for the Rest of Us
SIEM systems were first created for large enterprises and government agencies that were frequent targets of advanced cyber attacks. Back then, smaller and lower-profile organizations were able to get by with basic security tools as they were seldom the target of hackers. The world has changed and today cyber attacks have become so widespread and complex that small and medium-sized organizations need the same next-generation SIEM tools as large enterprises.
Next-generation SIEM technology uses advanced correlation techniques encompassing applications, transactions, pattern and behavior discovery, statistical and moving average anomalies, business process management, risk management, and global threat intelligence feeds.
Many organizations are caught between a rock and a hard place. They need industrial strength security, but do not have the people or the budget to run a security operations center (SOC) and administer a SIEM system. SIEM systems are typically complex to administer and require teams of people for monitoring events, experts for authoring use case content, and a lot of care and feeding.
We recommend resource-strapped organizations look at cloud-based offerings from new companies providing a SOC-as-a-Service. This new breed of Managed Security Service Providers (MSSPs) uses a cloud-based shared services model. There is no upfront investment in hardware and software and no requirement to hire a team of security and SIEM experts – instead customers pay subscription fees for a turnkey service.
