Web & Application Server Hardening Checklist

The working paper our auditors use to review web and application server builds. 32 controls across nine domains — installation & accounts, TLS, configuration, access control, HTTP security headers, logging, patching, attack-surface reduction and content protection — each with a test method, evidence, risk and remediation, mapped to CIS Benchmarks, OWASP, NIST CSF 2.0, ISO/IEC 27001:2022 and PCI DSS v4.0.1. Controls are vendor-neutral; the command reference maps each to Apache, NGINX, IIS and Tomcat.

Frameworks: CIS Benchmarks · CIS Controls v8.1 · OWASP · NIST CSF 2.0 · ISO/IEC 27001:2022 · PCI DSS v4.0.1
OEM coverage: Apache HTTP Server · NGINX · Microsoft IIS · Apache Tomcat · IBM WebSphere (equivalent)

What the web server hardening checklist covers

The checklist is vendor-neutral: the control questions apply across platforms, and a dedicated command reference gives the exact command or console path per platform. The 9 control domains are:

  • Installation, Accounts & Baseline
  • TLS & Transport Security
  • Server Configuration & Attack Surface
  • Access Control & Authentication
  • HTTP Security Headers & Response Hardening
  • Logging & Monitoring
  • Patch & Vulnerability Management
  • Content, Upload & Application Protection
  • Availability & Resilience

Which platforms it applies to

One checklist, every platform. The command reference covers:

  • Apache HTTP Server
  • NGINX
  • Microsoft IIS
  • Apache Tomcat

How auditors use it

Work top to bottom, set each control to Pass, Fail, Partial, Not Applicable or Not Tested, and attach an evidence reference. The Excel workbook includes a live dashboard (pass rate, open findings by priority), a findings register, an evidence-request list and a weighted risk-scoring model — so the review becomes a repeatable, evidence-based exercise.

Framework mapping built in

Every control carries practical mappings to CIS Benchmarks and CIS Controls v8.1, NIST CSF 2.0, ISO/IEC 27001:2022, PCI DSS v4.0.1 and the UAE IA / KSA ECC regional controls — so one review evidences several obligations at once. The mappings are practical audit mappings, not a substitute for the licensed text of each standard.

Frequently asked questions

What is a web server hardening checklist?

It is a structured list of security controls used to reduce attack surface and configure web server securely. This one contains 31 controls, each with a test method, the evidence to collect and the risk if it is missing.

Which platforms does it cover?

The control questions are vendor-neutral and a dedicated command reference gives the exact command or console path for Apache HTTP Server, NGINX, Microsoft IIS, Apache Tomcat.

Is it aligned to CIS Benchmarks and PCI DSS?

Every control is mapped to CIS Benchmarks and CIS Controls v8.1, NIST CSF 2.0, ISO/IEC 27001:2022 and PCI DSS v4.0.1, plus UAE IA and KSA ECC — so a single review supports several compliance obligations.

What format is the download?

You get a 12-sheet Excel working checklist (with a live dashboard, findings register and command reference) and a matching PDF narrative workbook. Both are free.

Can CyberSigma run this review for us?

Yes — our CERT-In empanelled auditors perform independent configuration reviews and hardening assessments against this checklist, with a prioritised findings report and remediation support.
