Server Configuration Review (Windows, Linux, Unix)
Why it matters
Many successful attacks do not rely on zero-day vulnerabilities. Instead, attackers exploit weak server configurations, excessive privileges, and insecure defaults that quietly exist across environments.
Our Server Configuration Review evaluates how securely your Windows, Linux, and Unix servers are configured and how those configurations could be abused by attackers. The focus is on identifying hardening gaps, privilege issues, and misconfigurations that increase attack surface or enable lateral movement.
This service provides a clear view of configuration risk across critical server infrastructure.
What We Review
Operating system hardening and baseline settings
User and privilege management
Authentication and access controls
Patch management and update practices
Logging, monitoring, and audit configurations
Network exposure and service configuration
Our Differentiated Approach
We assess configurations based on how attackers exploit them in the real world.
Attacker-perspective review of server configurations
Context-aware analysis based on server role and exposure
Manual validation to avoid false positives
Actionable hardening guidance, not generic checklists
How We Deliver
Server Inventory & Role Understanding
We identify in-scope servers and understand their purpose, exposure, and criticality.
Configuration Analysis
We review system configurations against secure baselines and attacker abuse patterns.
Privilege & Access Evaluation
We assess user rights, service accounts, and access controls to identify escalation paths.
Risk Validation & Prioritization
Findings are validated and prioritized based on exploitability and business impact.
Reporting & Remediation Support
We deliver clear findings with practical hardening recommendations.
Key Deliverables
Executive summary with configuration risk overview
Detailed hardening and misconfiguration findings
Privilege and access control analysis
Risk-based remediation recommendations
Optional validation after configuration changes
Business Outcomes
Reduced attack surface across servers
Lower risk of privilege escalation and lateral movement
Improved system stability and security posture
Better alignment with security baselines
Increased confidence in server hardening
Standards & Best Practices
Our server configuration reviews align with industry benchmarks and real-world attack techniques, including:
CIS Benchmarks for Windows, Linux, and Unix
NIST system hardening guidance
Attacker-observed configuration abuse patterns
Why Our Server Configuration Review Is Different
Many reviews rely solely on automated checks. We focus on how configuration weaknesses are actually abused, delivering insight that leads to meaningful risk reduction.

SISA’s Breach and Attack Simulation gave us practical visibility into how our security controls performed under real-world attack scenarios. The simulations across external, internal, and O365 environments helped us identify which controls were effective, where gaps existed, and what needed immediate attention. Because SISA’s detection capabilities were already integrated into our environment, we could also better understand how attacks were detected and handled across different stages of the simulation. What stood out most was the transparency of the engagement and the actionable guidance the team provided throughout the process.
