SIEM (Security information and event management) is a methodology to security management that groups SEM (security event management) and SIM (security information management) functions into one security management system.
The fundamental principles of the SIEM system are to collect relevant data from various sources, identify abnormalities from the norm and take suitable action. For instance, when an impending issue is detected, a SIEM system might log additional information, create an alert and warn other security controls to discontinue an activity's progress.
SIEM systems work by hierarchically installing several collection agents, to collect security-related events from servers, end-user devices, and network equipment, and also from dedicated security equipment, such as intrusion prevention systems (IPSes), antivirus and firewalls. The collector’s forward events to a centralized management console, where security analysts sift through the noise, connect the dots and prioritise security incidents.
Why is SIEM important?
With SIEM organizations can easily manage security by segregating massive amounts of security data and prioritizing the security alerts the software generates.
SIEM software allows security teams to detect incidents at an early stage. SIEM evaluates the log entries to detect signs of malicious activity. It also enables organizations to determine the nature of the attack and its impact on the business, as the system collects events from various sources across the network, it can reconstruct the timeline of an attack.
Next-Gen SIEM Benefits:
Comprehensive Visibility: Ingests raw streaming data (Flows, Logs, Identity) with millions of enrichment, logically auto-discovered and creates asset groups and Works transparently with encrypted traffic
Proactive Threat Detection: Proactively detects known and unknown threats and surfaces them in near real-time without an agent or alert fatigue. Reduces MTTI with Proactive Threat Detection, Performs threat detection across multi-cloud, on-premise, and hybrid environments
Continuous Compliance: Reports for regulatory compliance (HIPPA, PCI, NIST, FINRA, GDPR, etc.), Security operation and investigation support and Long-term data analytics
Automatic Containment and Elimination
- Reduces MTTR with Automatic Threat Remediation in real-time
- Provides clear actionable steps to contain & eliminate threats
- 50% SoC productivity improvement
Security information and event management tools
SIEMs offer a lot of promise, but legacy SIEMs simply can't keep up with the rate and sophistication of today's cyberattacks. Organizations today require access to analytics-driven SIEMs, the likes of Splunk, that combine a big data platform that is optimized for machine data with advanced analytics, threat detection, monitoring tools, incident response tools and multiple forms of threat intelligence. Arcsight ESM, IBM QRadar and Splunk are among the most popular.
ArcSight gathers and analyses log data from an organizations applications, operating systems and security technologies. Security personnel will automatically receive alerts from the system, once a malicious threat is detected.
ArcSight not only automatically alerts it also perform an automatic reaction to end the malicious activity. Another feature is the ability to integrate third-party threat intelligence feeds for more accurate threat detection.
IBM QRadar collects log data from sources in an enterprise’s information system, including network devices, operating systems, applications and user activities.
The QRadar SIEM analyzes log data in real-time, enabling users to quickly identify and stop attacks. QRadar can also collect log events and network flow data from cloud-based applications. This SIEM also supports threat intelligence feeds.
Splunk Enterprise Security provides real-time threat monitoring, rapid investigations using visual correlations and investigative analysis to trace the dynamic activities associated with advanced security threats.
The Splunk SIEM is available as locally installed software or as a cloud service. It supports threat intelligence feed integration from third-party apps.
Continuous Security Events Monitoring with Cymune:
SIEMs offer a lot of promise, but legacy SIEMs simply can't keep up with the rate and sophistication of today’s cyberattacks. SIEMs analytics-driven approach helps organizations to combine a big data platform that is optimized for:
We give you a SIEM that’s equipped with all this & helps your organization to Accelerate the investigation of system incidents & ample control for your security teams. We give you a single-pane-of-view to monitor real-time security issues & respond to security alerts to keep attackers at bay.
Why Choose Cymune for Continuous Security Events Monitoring:
Finding a mechanism to collect, store and analyze security only data is relatively simple. However, collecting all security-relevant data and turning all that data into actionable intelligence is a whole other matter. Our analytics-driven SIEM allows IT to monitor threats in real-time and respond quickly to incidents so that damage can be avoided or limited.
Real-Time Monitoring& Advanced Analytics: Threats can move quickly, and IT needs the ability to monitor threats and correlate events in real-time to find and stop threats faster. Analytics are key to producing insights from mountains of data, and machine learning can automate this analysis to identify hidden threats.
Incident Response& User Monitoring: IT needs an organized way to address and manage a potential breach and the aftermath of a security breach or attack to limit damage and reduce recovery time and cost. Monitoring user activity with context is critical to pinpoint breaches and uncover misuse. Privileged user monitoring is a common requirement for compliance reporting.
Threat Intelligence: Threat intelligence can help IT recognize the abnormal activity, assess the risk to the business, and prioritize the response. Security professionals need specialized tools to monitor, analyze and detect threats across the kill chain.
