Security Information Event Management
 “SIEM” is defined as a group of complex technologies
that together, provide a centralized bird’s-eye-view
into an infrastructure. Furthermore, it provides
analysis and workflow, correlation, normalization,
aggregation and reporting, as well as log
management.
SIEM Advantages
•

•
Correlation of data from multiple systems and from different events detecting security
and operational conditions
Anomaly detection by using a baseline of events over time to find deviations from
expected or normal behavior
Comprehensive view into an environment based on event types, protocols, log sources,
etc
APT (advanced persistent threat) protection through detection of protocol and
application anomalies
Prioritization based on risk of threat to assets, staff can triage the most vulnerable
targets
Alerting and monitoring on events of interest to escalate priority
Ability to filter events and create custom views to meet business needs
Allows organizations to demonstrate adherence to polices and controls
Monitor and log the access and use of sensitive data
Limits exposure to breach disclosure costs by knowing the number or customer
records affected
Helps reduce risk to business partners and customers by detecting data loss and fraud
Reduce costs by replacing redundant functions and technologies

 Any type of log that you manage: system logs, webserver logs,
error logs, and app logs
 Filter. Parse & transform your data on the fly.
Kibana
 Kibana is your log-data dashboard
 Leverage the Elastic Maps Service to visualize geospasial.
 Perform advanced time series analysis on your Elasticsearch data
with time series UIs.
 Analyze relationship with graph
 Explore anomalies with machine learning
