Server Security

We harden Linux and BSD servers to CIS benchmark level, audit them quarterly, and respond to intrusions when they happen. SELinux/AppArmor enforcement, fail2ban + CrowdSec, WAF rule curation, intrusion detection (Wazuh, OSSEC, Falco), file-integrity monitoring (AIDE, Tripwire), and continuous CVE patching — coordinated so a kernel upgrade does not take down your cluster.

We also handle access management: SSH key rotation, just-in-time bastion access, hardware token (YubiKey) enrollment, secrets rotation, and audit-log shipping to immutable storage. If you are chasing SOC 2, ISO 27001, HIPAA, HITECH, PCI-DSS, or FedRAMP compliance, we know what auditors look for and what they will accept as evidence — and we have shipped HIPAA-compliant Rails workflows with FHIR / HL7 data exchange and audit-friendly patient-data handling.

When incidents happen, we follow a documented IR playbook: contain, eradicate, recover, learn. Forensic timeline, IOC extraction, customer-comms drafting, and a blameless postmortem within 48 hours.
