Firewalls generate enormous volumes of logs that contain critical threat intelligence. Integrating firewall logs into your SIEM unlocks network-level threat detection, policy violation alerting, and correlation with endpoint and identity events to detect sophisticated attacks.
Blogs / Network Security Monitoring with SIEM | Firewall Integration Guide | Codesecure
Network security monitoring through SIEM gives organisations visibility into traffic flows, connection patterns, and policy violations that no single tool can provide alone. Firewall logs are the primary data source for network-level threat detection and must be correctly ingested, parsed, and correlated to be useful.
IAM is the foundation of cloud security. Enforce MFA on all accounts, especially root and admin. Implement least privilege access. Users and services should only have permissions they need. Use IAM roles instead of long-lived access keys. Regularly audit permissions and remove unused accounts. Set up centralised identity with SSO where possible.
Encrypt data at rest using platform-managed or customer-managed keys (KMS). Enforce TLS for all data in transit. Use private subnets for databases and internal services. Never expose them to the public internet. Implement security groups with deny-by-default rules. Enable VPC flow logs to monitor network traffic. Use secrets management services (AWS Secrets Manager, Azure Key Vault) instead of hardcoding credentials.
Enable cloud audit logging (CloudTrail, Azure Activity Log) across all regions and accounts. Set up real-time alerting for suspicious activities — failed logins, privilege escalations, resource deletions. Use configuration compliance tools (AWS Config, Azure Policy) to detect drift from security baselines. Map your controls to relevant frameworks — CIS Benchmarks, SOC 2, ISO 27001, RBI guidelines — depending on your industry and regulatory requirements.
Conclusion
Cloud security is not a one-time setup. It requires continuous monitoring and improvement. By implementing these foundational practices early, enterprises can scale confidently while maintaining a strong security posture.
