But it’s critical to realize that MSSPs are not a replacement for a SOC. The MSSP provides its own analysts, which means you don’t have to hire and train your own security personnel.Īn MSSP relieves the pressures of alert fatigue, ongoing SIEM management, the struggle to find qualified security analysts, and overall maintenance costs. When you outsource all or most of your security, you don’t need to own and manage security tools in-house because the MSSP handles the hardware and software updates, the system optimization, and the ongoing management of those resources. Managed security services are an increasingly popular option for a simple reason: They provide an affordable, subscription-based security model. Some organizations outsource all their security functions to MSSPs, while others use a provider to supplement their in-house capabilities and bridge gaps. Managed security services providers (MSSPs) are IT security providers that monitor, maintain, and manage security 24×7. It’s no longer enough by itself, which is frustrating, considering its high costs. Bottom LineĪ SIEM has its place as a data ingestion tool in a SOC, and will for the foreseeable future, but it lacks the ability to perform meaningful analysis that will reduce false positives. Requires continuous tuning and updates for new threats. SIEM ConsĬomplex, labor-intensive, expensive, noisy, limited in its insights. Great for data aggregation and event correlation for help with threat detection helps streamline compliance. A SIEM solution is also time-consuming and can take up to a year to implement. High Total Cost of Ownershipīecause of the above issues, a SIEM requires constant attention, unending configuration maintenance, and the expertise of experienced security analysts and incident responders. Phishing scams, fileless malware, advanced persistent threats, and zero-day exploits are notorious examples of such silent subterfuge. MissesĪlso known as false negatives, misses happen when an event appears innocuous because it doesn’t violate a SIEM rule but is actually a viable threat. The result is a large number of false positives, which contribute to alert fatigue. A SIEM reduces this number, but the SIEM’s context is limited to its rules, which can quickly require updating in a rapidly-changing threat landscape. SOC analysts sift through tens of thousands- up to hundreds of thousands -of daily alerts on average. What Are the Disadvantages of SIEM? False positivesīillions of network events may occur in a single day. Since then, the technology has gone through iterations to improve and enhance its capabilities.ĭespite these advances-and the fact that SIEM is a security mainstay for countless organizations-its effectiveness for threat detection and response is hampered by several factors. When SIEMs came to the market almost 15 years ago, many practitioners considered the combination of information management and event management ground-breaking. On the other hand, since the rules are static, a SIEM is most effective against known rather than unknown threats. This makes it relatively easy for security analysts to identify possible threats on the network. The standard SIEM relies on rules-based programming, meaning event alerts can only be triggered based on pre-designated configurations. The SIEM collects and aggregates data from different devices, security tools, and appliances, such as network devices (e.g., routers and domain controllers), endpoint security (antivirus, endpoint detection and response), intrusion detection or intrusion prevention systems, honeypots, and so on. It integrates with various IT systems and log flows to ingest data for event analysis via a central console.Īs the name somewhat implies, SIEM combines security event management (SEM)-which monitors, gathers, analyzes, and correlates log and security-event data in real time-and security information management (SIM), which provides more of a historical, long view of the log data, as well as reporting. Security information and event management (SIEM) is the cornerstone technology of a SOC. Here’s our take on the pros and cons of the three security models and how to identify the right solution for your organization. Which one is most viable for your organization?
