Benefits of Using SIEM
SIEM software provides a powerful way for organizations to detect the latest security threats to their networks. SIEM provides a holistic view of an organization’s IT security by providing real time reporting coupled with long-term analysis of security events. SIEM software logs event records from sources throughout a network. Those logs provide important forensic tools to an IT staff, which the software then helps to analyze. Complete log collection helps address many compliance reporting requirements. Parsing and normalization maps log messages from different systems into a common data model and enables analyzing related events, logged in different source formats. Correlation links log events from disparate systems or applications, which speeds the detection and reaction to security threats. SIEM aggregation reduces the volume of event data by consolidating duplicate event records and reporting on the correlated, aggregated event data in real time, comparing it to long-term summaries.
Solving Problems Using SIEM
Multiple threats to the security of networks are emerging and spreading rapidly. There are more possible points of entry into any network because of the increase in user mobility, the number of remote locations that might exist, and the sheer number of devices accessing the network.
New applications and technologies create risks and invite new attacks on networks. In organizations, security breaches can go completely undetected for months, while others have IT departments dedicated to protecting a network against malicious activity. They must analyze data from a multitude of sources to understand threats facing a network, and determine actions to address threats.
What IT staffs need is a complete and holistic solution that provides layered security to protect from threats that occur at all layers and locations of a network. IT departments also need to keep abreast of compliance requirements, providing:
- Accountability that can survey the reports on who did what and when.
- Transparency that can provide visibility into the security controls, business applications, and assets that are being protected.
- Measurability that can provide metrics and reporting around IT risks within a company.
Juniper Networks SIEM
Juniper Networks Secure Analytics (JSA) is a network security management platform that facilitates the comparison of data from the broadest set of devices and network traffic. It combines log management, SIEM, and network behavior anomaly detection (NBAD), into a single integrated end-to-end network security management solution. For the Payment Card Industry (PCI), the Federal Information Security Management Act (FISMA), or other compliance-driven organization, administrators get a complete picture of their network security posture.
