Managing security of any IT infrastructure requires resources for timely threat detection and response. The IT infrastructure tends to become more and more complex as business grows and automation tools become necessary for maintaining sufficient security level.
These tools must provide the personnel with means to oversee the general status of the infrastructure and the underlying network, detect various security incidents and respond to them. Real-time event collection from several sources such as firewalls, anti-virus, etc. related to unauthorized activities is essential.
When the workload imposed on security staff and officers affects security quality, a properly deployed SIEM solution can ensure required automation.
SIEM collects, filters and normalizes security events, processes the collected data to detect correlations and trends. This mechanism enables to detect anomalies, potential infrastructure failures, unauthorized access attempts and hacker attacks.
Although a threat can be invisible to general security management tools, it will be detected by SIEM as a result of correlation between several events from different data sources.
SIEM technology is a “single-window” tool for information security officers to ease and streamline incident research and improve response speed and quality.
SIEM performs:
- event collection, processing and analysis for numerous sources within the infrastructure
- real-time detection of hacker attacks, policy breaches and similar incidents
- security status evaluation for IT, networks and other resources which are critical for business
- report generation
SIEM advantages for the Customer:
- lower staff training costs: a single tool to master
- improved IT/Security staff efficiency in large infrastructures with multiple monitored entities
- security status control automation and report generation in compliance with industry and worldwide standards (PCI DSS, ISO 27001)
- lower security risks due to improved threat detection and response times
- permanent status control and monitoring of the enterprise IT infrastructure, lower downtimes
- relevant and objective security system efficiency evaluation based on retrospective incident analytics
- centralized event and incident data storage
SIEM is a key to optimize workload for information security officers, it enables to automate route tasks and save personnel time for tasks that require human intelligence, and bring enterprise security management to the next level.
