The Security Information and Event Management (SIEM) solution includes the design and implementation of a centralized platform for collection, correlation, and analysis of security events from multiple IT and OT infrastructure sources.

The architecture is structured to consolidate logs from network devices, servers, firewalls, authentication systems, corporate applications, CCTV environments, and other critical assets, enabling early incident detection and coordinated response.

A3A Engenharia de Sistemas develops each solution based on mapping of log sources, definition of security use cases, and modeling of correlation rules, ensuring systemic visibility, technical traceability, and structured support for security governance.

SCOPE OF WORK

Within the scope of SIEM solutions, A3A Engenharia de Sistemas can operate in the following areas:

Planning and Architecture

  • Inventory of assets and log sources
  • Definition of priority use cases such as intrusion detection and anomaly detection
  • Structuring of centralized or distributed architecture
  • Sizing of retention, search, and event correlation capacity

Implementation and Integration

  • Onboarding of network, server, application, and security logs
  • Configuration of parsers, collectors, and normalization routines
  • Implementation of dashboards, alerts, and correlation rules
  • Integration with IAM, firewall, endpoint, and SOC processes

Monitoring and Governance

  • Continuous analysis of events and indicators
  • Definition of escalation and response workflows
  • Audit trail consolidation and reporting
  • Documentation of SIEM technical architecture and operating model

Evolution and Optimization

  • Inclusion of new log sources and use cases
  • Tuning of rules to reduce false positives
  • Integration with SOAR and advanced analytics
  • Expansion of coverage for hybrid and critical environments

APPLICATIONS AND ENVIRONMENTS

The solution applies to:

  • Corporate environments
  • Critical infrastructures
  • Industrial plants with IT and OT assets
  • Electronic security operations
  • Organizations with compliance and traceability requirements
  • Environments with high exposure to cyber incidents

The architecture is sized to ensure continuous visibility, centralized incident analysis, and consistent support for technical security governance.
