Top SIEM Challenges for SMEs

SIEM is like clockwork—it needs constant “winding”

For a decade, security information and event management (SIEM) tools have represented the gold standard in enterprise security. SIEMs offer a single pane of glass for an entire organization’s security posture, monitoring logs, aggregating data, and providing alerts to security staff. When integrated with a team of experts into a security operations center (SOC), a SIEM functions like a finely-tuned watch.

But like clockwork, a SIEM requires constant “winding” and maintenance—staff to monitor alerts, staff to customize the SIEM tool, staff to update definitions and maintain security in the face of evolving threats. This complexity means SIEM tools may not be the best fit for small to midsize enterprises (SMEs).

  Staffing challenges

SIEM tools need active, continuous tuning to ensure you get actionable results. A SIEM generates thousands of alerts and notifications which must be acknowledged, investigated, and, if they are attacks, defeated and remediated. Managing a SIEM and the associated agents and log sources is a full-time job, which requires several full-time trained security engineers.

  Complex to deploy and maintain

A SIEM has a long deployment cycle, varying from 3 to 6 months, with a high risk of failed deployments. A long and labor-intensive deployment cycle means high upfront costs, and an extended period during deployment where security is not actually in place. Furthermore, filtering algorithms, correlation rules, and parsing from new event sources need constant tuning and updating to perform against new threats, increasing the ongoing costs of a SIEM.

SIEM challenges include:

  Dedicated SOC

A Dedicated SOC is a centralized SOC that has a dedicated infrastructure, team, and processes. It is self-sustained for continuous operations. It has 5-8 security experts at various levels for 24x7 monitoring and operations. It is best suited for large enterprises and government agencies who are constantly at risk of attack. This model of SOC is essential for global companies with private data in various locations that must comply with regulations and security policies.

  A Command SOC—and Its Challenges

Global 2000 companies, large telecom providers, and defense organizations use this model of SOC because it has multiple SOCs distributed globally or in various locations. A command SOC typically controls other SOCs and is more focused on managing threat intelligence and situation awareness than day-to-day operations. It is also used for forensics and other recovery processes. The Command SOC is managed by a large team of security experts and a security research team with hunting capabilities.

   The Best Choice

SOC-as-a-service is an outsourced model that extends the capabilities of a company’s IT team and provides end-to-end security. It includes a managed detection and response (MDR) service, which removes the burden of determining the best methodology or technology for threat detection and response. The Arctic Wolf SOC-as-a-service leads the industry in making security simple, actionable, and affordable. Arctic Wolf is anchored by a Concierge Security™ Team who uses the Arctic Wolf platform to provide tactical and strategic insights into your security to answer the question, “Am I safe?”

Despite significant investments in network and application security, many companies continue to experience costly and damaging security breaches. A SOC- as-a-service managed security model augments current network security tools with continuous threat monitoring, detection, and response.
