SIEM Monitoring

The Limits Of SIEM Monitoring

Security information and event management, or SIEM, provides a real-time view of an organization’s security posture and the threats it faces. By aggregating and analyzing data from a wide range of internal sources, SIEM monitoring solutions can spot abnormal behavioral, detect threats, pinpoint security breaches, and issue alerts for IT staff to follow up on.

However, SIEM solutions alone can’t provide organizations with comprehensive approach to improving security performance or managing risk. To augment the valuable insight produced by SIEM monitoring solutions, organizations need additional tools that can strengthen their security programs with objective, independently validated information. They need tools for benchmarking performance, and solutions that can help organizations better manage third-party risk. That’s why, when seeking a clearer view of their security posture, a growing number of organizations around the world are turning to Security Ratings from BitSight.

SIEM Monitoring VS. Security Ratings

Many organizations are unsure whether they need both a SIEM monitoring solution and a security ratings solution. Both offer significant value but provide very different perspectives on security.

SIEM software collects log and event data from a wide range of sources: applications, network devices, domain controllers, servers, firewall logs, and other sources. Combining vast amounts of data on a centralized platform, SIEM technology performs analysis to identify threats and enable security teams to follow up on alerts.

The intelligence produced by SIEM solutions is based solely on internal sources and provides no external data that can offer context. SIEM monitoring can’t show an organization what its attack surface looks like from the outside, or how its cybersecurity posture has measurably improved over time. And SIEM technology can flood IT teams with alerts without offering any help to prioritize them for remediation.

That’s where security ratings can help. Providing an objective, verifiable view of an organization’s security posture, security ratings are designed to provide greater visibility into an attack surface and reveal vulnerabilities in IT infrastructure. Security ratings enable organizations to easily benchmark their performance over time. And where a flood of alerts from SIEM monitoring can easily overwhelm an IT staff, security ratings help to provide context and clarity that lets teams to easily prioritize remediation efforts on areas of greatest risk.

BitSight Security Ratings

BitSight Security Ratings provide a data-driven, dynamic measurement of an organization’s cybersecurity performance. Like credit scores, BitSight ratings are an outside-in view of security posture – they’re based solely on information that is externally available, and they require no internal information from the rated organization.

Updated daily, BitSight Security Ratings can serve as a tool for continuous monitoring of an organization and its third-party network. Ratings are calculated on objective data that details an organization’s security performance in relation to 23 risk vectors in four general categories: compromised systems, user behavior, security diligence, and publicly disclosed data breaches. Ratings run from 250 to 900 – higher ratings indicate that an organization is more effective at implementing good security practices.

Most important, external research shows that BitSight security ratings correlate to data breaches, providing organizations with extraordinary insight into their own vulnerabilities and those of their vendors. For example, companies with a BitSight Security Rating of 700 or higher are nearly 5 times less likely to have a breach than those with a rating of 500 or lower.

Solutions to Complement SIEM Monitoring

The BitSight Security Ratings platform provides organizations with a number of solutions that help to solve complex cyber risk challenges when implemented alongside SIEM solutions.

  • BitSight for Security Performance Management enables security teams to continuously monitor, measure, and communicate the efficacy of cybersecurity controls they have in place to secure the organization. With BitSight, organizations can rely on continuous cyber security monitoring to gain clear visibility into the performance of their security program and align investments and actions to deliver the highest impact over time. BitSight for Security Performance Management enables security teams to efficiently allocate limited resources to the areas of highest cyber and cloud security risk, and to support data-driven conversations with key stakeholders around issues of cybersecurity governance. BitSight also offers the capability to financially quantify the risk living on an organization’s network to help prioritize risks that would cost an organization the most if acted upon.
  • BitSight for Third-Party Risk Management provides the automated tools risk managers need to continuously measure and monitor the security posture of all vendors connected to their network. BitSight immediately exposes cyber risk within a supply chain, helping risk management teams to work with vendors to achieve measurable risk reduction. With BitSight, organizations have clearer insight into the most significant risk issues impacting each vendor, enabling an adaptive and tiered approach to prioritizing remediation within an organization’s third-party cyber risk management program.

FAQs: What Is Attack Surface Monitoring?

Security information and event management (SIEM) is a software technology that aggregates and analyzes data from antivirus events, firewall logs, and other sources in an IT environment. By collecting data about security events, SIEM monitoring software can uncover trends, detect threats, and issue alerts to IT staff who can take swift action to mitigate attacks.

By aggregating and analyzing data from a wide number of sources within an IT environment, SIEM monitoring provides greater visibility into security events and provides more timely alerts when threats are detected. The primary disadvantage of SIEM monitoring is that it is not a set-it-and-forget-it solution. It requires 24/7 attention from a trained staff to extract business value.

Security ratings provide a comprehensive, outside-in view of an organization’s security performance. Ratings are based on externally available data, rather than internal sources, ensuring that ratings are objective and verifiable. Ratings are typically calculated based on evidence of compromised systems, user behavior, security diligence, and public disclosures of data breaches.
