For comprehensive security visibility, organizations need a Security Information & Event Management (SIEM) solution that provides actionable intelligence that security professionals can rely on to quickly understand threats and prioritize response. 

Security Information & Event Management (SIEM)

Security information and event management, known as SIEM (pronounced ‘sim’), is a software solution that stores, aggregates and analyzes enterprise data. SIEM collects this data from across an entire information network and uses it to present IT and security teams with intelligence and monitoring capabilities that show various forms of network activity including:

  • Failed and successful logins
  • Unplanned escalation of privileges
  • Behavioral information related to abnormal network traffic patterns
  • Network traffic associated with malware activities (including ransomware)

For comprehensive security visibility, organizations need a SIEM solution that provides actionable intelligence that security professionals can rely on to quickly understand threats and prioritize response. 

How does SIEM work?

SIEM tools pull data from network devices, servers, domain controllers and many other sources. Next, SIEM aggregates and normalizes the data, which condenses a vast amount of information into digestible segments that can be easily analyzed. Security teams review the segments, checking for trends or behavior that raise red flags. Detecting these threats becomes easier when the trends and subsequent behaviors are predictable. Finally, SIEM zeroes in on where breaches may occur and grants teams time to investigate and map out a plan of response.

Organizational security teams define the rules that a SIEM solution follows. When a rule is broken or threatened, SIEM tools provide an alert. Typically, rules are applied two ways: network-wide or within the network on a segmented basis. Regardless of how the rules are issued, SIEM monitors data usage and behavior and helps teams identify the specific type of threat.

Think of a SIEM as a data aggregator, as well as a search and reporting solution. However, as useful as this information is, it can be difficult for teams to understand what steps to take if they lack context surrounding the information. The amount of data ingested and correlated by the typical SIEM is vast, and the rules defined by security teams can be complex, so it’s imperative to clearly understand what analysis reporting means to your organization and what remediation steps are required. InfoSystems helps to address the full scope of your SIEM implementation, from initial consulting and architecture design to a complete ground-up deployment.

Understand Capabilities & Maintain Compliance

SIEM real-time capabilities include information management and event management. Information management collects security data from across an enterprise network, such as firewalls, antivirus tools and intrusion detection, while event management focuses on events that threaten network health, such as human error, design flaws and malicious code. Collectively, the two capabilities heighten an enterprise’s defensive posture.

SIEM has come a long way since its introduction more than two decades ago. In addition to collecting and analyzing data, a SIEM can programmatically be configured to perform specific actions based on pre-determined response to suspicious events. When correctly implemented, SIEM is an incredibly useful tool to help ensure regulatory compliance around HIPAA, PCI, NIST and GDPR requirements. Specific compliance templates that are natively available with most SIEMs maintain standards and alert the security team or help desk if a behavior, a potential security breach or other data sharing practice compromises compliance regulations.

Maximize your SIEM Investment

SIEM brings tremendous value to the enterprise. However, it can be complicated to manage and difficult to develop swift and effective plans based on the data the SIEM delivers. Infosystems can help drop deployment time from months to minutes utilizing cloud-based SIEM services that provide clients with instant access to reporting data customized to specific security needs. The streamlined process cuts down on false positives and escalates real threats directly to IT and security teams.

InfoSystems believes organizations should focus on business value, not the IT that powers it. InfoSystems provides the following services to maximize the value you receive from your chosen SIEM solution:

  • Ground-Up Installation
