Server Security Audit - Harden Your Infrastructure Before It's Compromised
A systematic server security audit of your Windows or Linux infrastructure. I find misconfigurations, exposed services, and privilege escalation paths, then help you close them.
A server security audit reveals the misconfigurations, exposed services, and access control weaknesses that attackers exploit to breach your infrastructure. I perform comprehensive server security assessments on Windows Server and Linux systems, covering OS hardening, firewall rules, network segmentation, user privileges, and malware detection. Every server security audit follows CIS benchmarks and delivers a prioritized hardening checklist.
Risks Lurking in Your Infrastructure
Unnecessary Services Exposed
Default configurations leave ports open, services running, and management interfaces accessible to the entire internet. Every exposed service is an attack vector.
Weak Access Controls
Shared admin passwords, unused accounts with elevated privileges, and SSH keys without passphrase protection. Common issues that turn small breaches into full compromises.
No Visibility Into Intrusions
Without proper logging, monitoring, and alerting, an attacker can dwell in your infrastructure for months before anyone notices.
Why This Server Security Audit Matters
Complete Attack Surface Review
I audit every layer of your server: OS, network, services, users, and logs to identify the full scope of your exposure.
CIS Benchmark Alignment
Server security audit recommendations follow CIS benchmarks and industry hardening guides for your specific OS version.
Malware and Rootkit Detection
I scan for known threats, suspicious files, hidden processes, and indicators of compromise.
Network Segmentation Review
Firewall rules, access control lists, and network architecture evaluated for proper isolation and least-privilege access.
Actionable Hardening Checklist
You receive a numbered, prioritized checklist, not a raw vulnerability dump. Each item explains the risk and the exact fix.
Optional Implementation
Choose the full tier and I'll apply every hardening recommendation, configure firewalls, and deploy monitoring tools myself.
The Server Security Audit Process
Scoping and Access
We define the servers in scope, access credentials, and any maintenance windows. I can work with SSH, RDP, or VPN access as needed.
OS and Configuration Audit
I review patch levels, kernel parameters, service configurations, user accounts, filesystem permissions, and startup scripts.
Network and Firewall Analysis
Port scanning, firewall rule review, network service enumeration, and traffic segmentation assessment.
Threat Detection
Malware scanning, rootkit detection, log analysis for suspicious activity, and integrity checking of critical system files.
Report and Remediation
Detailed findings report with severity ratings, CIS benchmark references, and step-by-step hardening instructions. Optional hands-on implementation.
What the Server Security Audit Covers
OS Hardening Review
Patch levels, kernel settings, unnecessary services, and security configurations.
Firewall and Network Audit
Open ports, firewall rules, network segmentation, and access control lists.
Access Control Analysis
User accounts, sudo/admin privileges, SSH/RDP configuration, and key management.
Malware and Rootkit Scan
Detection of known threats, hidden processes, and indicators of compromise.
Log and Monitoring Review
Logging configuration, audit trail coverage, and alerting recommendations.
Hardening Report
Prioritized findings with severity ratings, CIS references, and remediation steps.
Frequently Asked Questions About Server Security Audits
Which operating systems do you audit?
I audit Windows Server (2016, 2019, 2022) and Linux distributions including Ubuntu, Debian, CentOS/RHEL, Rocky Linux, and AlmaLinux. Both on-premise and cloud-hosted servers (AWS EC2, Azure VMs, DigitalOcean, Hetzner, etc.) are covered by my server security audit.
Do you need root or admin access for the server security audit?
For a thorough server security audit, yes, I need privileged access to review OS configurations, installed packages, user accounts, and log files. I can use a dedicated audit account that you create and revoke after the assessment. All access is documented in the rules of engagement.
Will the server security audit cause downtime?
The assessment itself is non-destructive. I review configurations and run scans that don’t affect service availability. If the implementation tier involves changes like restarting services or applying patches, we schedule those during your maintenance window.
How many servers can you audit?
Pricing is per-server. If you have multiple servers, I can provide volume pricing. Most clients start with their most critical production server and then expand to other hosts based on the initial findings.
Do you provide ongoing server monitoring?
The server security audit is a one-time engagement. However, as part of the implementation tier, I can set up monitoring tools (fail2ban, OSSEC, auditd, etc.) and configure alerting so your team is notified of suspicious activity going forward.
Secure Your Servers Before It's Too Late
Unsecured servers are the #1 target for ransomware, crypto-miners, and data theft. A thorough server security audit today prevents a costly incident tomorrow.
