SIEM Implementation and Migration
Veyzer's SIEM Implementation and Migration services help organizations stay ahead of potential security risks. A robust Security Information and Event Management (SIEM) system is crucial for comprehensive monitoring, threat detection, and incident response. As Splunk and Microsoft authorized partners, our SIEM Implementation and Migration services ensure that your organization is equipped with a tailored, efficient, and scalable SIEM solution to protect against emerging threats.
SIEM Implementation
We provide a complete journey through automation, orchestration, integration, and response.
Identify security goals and compliance requirements (e.g., HIPAA, PCI-DSS).
Evaluate SIEM Options
We create custom integrations between different systems, tools, components, and APIs - allowing you to connect and coordinate all of your activities.
Prepare Infrastructure and Data
We specialize in developing custom playbooks consisting of structured, readable, repeatable, and manageable workflow blocks.
Deployment and Configuration
We provide full workflow automation from A to Z - freeing you from time-consuming repetitive tasks and enabling you to focus on critical, higher-impact work.
Training and Operationalization
We train your team on SIEM functionality, custom rules, and dashboard usage, and define incident response procedures based on SIEM alerts.
Monitoring and Tuning
We perform daily log reviews, refine the SIEM as new threats emerge, and adjust correlation rules to optimize performance.
Requirements
Identify security goals: compliance (e.g., HIPAA, PCI-DSS), threat detection, forensic investigations, incident response, etc.
Inventory of IT assets: catalog systems, networks, and applications to monitor.
Define scope: determine the volume of logs, the type of events to monitor, and key performance metrics.
Evaluate SIEM Options
Cloud-based vs. on-premises: decide based on scalability, cost, and control. Cloud-based: easier scaling (Microsoft Sentinel). On-premises: high control over the infrastructure (e.g., Splunk Enterprise). Vendor selection: compare top SIEM solutions based on features like log collection and correlation capabilities, integration with existing security tools, threat intelligence and alerting features, compliance reporting, and user interface for real-time monitoring and investigation. Costs: evaluate licensing models (pay-per-volume vs. flat-rate licensing).
Prepare Infrastructure and Data
Network and system integration: ensure that network devices, servers, firewalls, databases, and security tools can send logs to the SIEM. Establish log sources: prioritize critical logs (firewalls, antivirus, IDS/IPS, etc.) and standardize log formats to ensure compatibility. Ensure time synchronization (NTP) across all log sources for accurate correlation. Define event correlation rules: identify common attack patterns and define rules that trigger alerts.
Deployment and Configuration
Agent deployment: install necessary agents on servers or configure devices to forward logs via syslog, SNMP, or API. Configure data collection: set up log ingestion based on your needs (real-time or batch processing). Create dashboards: customize dashboards to visualize key security metrics like event types, source IPs, and user activities. Set up alerts: define thresholds for suspicious activity (e.g., multiple failed login attempts) and tune the SIEM to minimize false positives. Test and optimize: test correlation rules using common attack scenarios (e.g., brute force, phishing) and review false positives to refine rules accordingly.
Training and Operationalization
Train SOC analysts on SIEM functionality, custom rules, and dashboard usage. Define incident response procedures based on SIEM alerts. For large environments, establish a 24/7 monitoring system for real-time response.
Monitoring and Tuning
Daily log reviews: analysts review and act on alerts. Tuning: refine the SIEM as new threats emerge and adjust correlation rules to optimize performance. Audit and compliance: regularly audit logs for compliance and security hygiene.
SIEM Migration
We can help migrate your SIEM solution from on-premises to hybrid or cloud. We can help you move from one vendor to Splunk or Microsoft Sentinel.
Migration Strategy
We decide on a migration strategy - whether it is a migration from an on-premises, hybrid, or cloud model, or transitioning between different SIEM vendors.
Assessment of Current SIEM
We conduct an assessment of your current SIEM environment, including all data sources, log retention policies, integrations, searches, alerts, and visualizations - ensuring nothing is missed.
Migration and Transition
Depending on the agreed migration type, we configure new data sources, migrate all existing configuration, dashboards, and alerting rules. We test and validate the new service and recommend running both systems in parallel for a period to ensure no data loss.
Decommissioning
We move historical data to ensure the new SIEM service has access to it and back up existing data. We gradually decommission the old SIEM service with a smooth handover, providing training to guarantee operational readiness.
