Security Compliance & Systems Hardening

Cybersecurity & Risk Hardening

Defense-grade infrastructure hardening, DoD STIG attestation, and zero-trust segmentation for sensitive enterprises.

Perimeter defenses alone cannot prevent lateral movement or administrative privilege exploitation. Sysad Solutions applies rigorous Department of Defense (DoD) DISA STIG guidelines, CIS benchmarks, and zero-trust architecture to turn your Linux infrastructure and databases into impenetrable security enclaves.

100%
STIG & CIS Audit Compliance Target

Operational Challenges Addressed

Complex federal regulatory audits (DoD STIG, NIST 800-53, CMMC) requiring exhaustive attestation
Overprivileged administrative credentials and missing multi-factor bastion gatekeeping
Unencrypted communication channels between backend application tiers and in-memory databases
Vulnerable default OS configurations exposing kernel surfaces to internal lateral attacks

Technical Capabilities & Architecture Scope

Granular engineering execution provided during active client engagements.

DoD DISA STIG & CIS Benchmark Compliance

Automated scanning, manual verification, and configuration lock-downs for enterprise Linux and databases.

Full implementation of RHEL, SLES, and Ubuntu DISA STIG baselines
Elimination of insecure legacy protocols (Telnet, rsh, unencrypted SNMP)
Kernel hardening: disabling suid dumpable, core dumps, and unneeded modules
Formal Plan of Action and Milestones (POA&M) mitigation documentation

Cryptographic Key Architecture & Data-at-Rest Encryption

Protecting persistent storage, volume snapshots, and redo logs with hardware-backed encryption.

FIPS 140-3 compliant encryption for block storage and database persistence
Integration with external Key Management Services (AWS KMS, Azure Key Vault, HashiCorp Vault)
Tamper-evident System Security File System (SSFS) key rotation protocols

Zero-Trust Enclaves & Network Micro-Segmentation

Isolating critical application clusters from unauthorized internal and external traffic.

Strict host-based firewall rules (firewalld, nftables) restricting SQL ports to application servers
Mutual TLS 1.3 authentication between NetWeaver application layers and databases
Hardened Bastion Jump Hosts with ephemeral SSH certificates and session recording

SIEM Integration & Immutable Audit Logging

Guaranteeing tamper-proof logging of all administrative and authentication activities.

Granular database audit policy definition capturing role changes and schema modifications
TLS-encrypted Syslog-NG forwarding to Splunk, Microsoft Sentinel, or Elastic
Real-time alerting on unauthorized authentication attempts and privilege escalations

Execution Lifecycle & Methodology

Structured engagement phases designed to minimize operational risk and verify stability.

01

Security Posture Assessment

We run automated SCAP compliance scans and perform an architectural review of your network topology, accounts, and cryptographic posture.

02

Vulnerability Prioritization

We categorize all findings into CAT I (critical), CAT II (high), and CAT III (medium) threats with explicit business impact mapping.

03

Hardening & Remediation Deployment

We deploy version-controlled Ansible playbooks to remediate findings across operating systems and database layers systematically.

04

Continuous Verification & Attestation

We deliver auditor-ready compliance documentation and set up automated drift detection to prevent regression.
