Server Hardening

Misconfigured servers remain a top cause of data breaches in 2024. With CERT-In’s 2022 
directive requiring organizations to report incidents within six hours, and growing cloud workload 
density, server hardening has moved from a best practice to an operational necessity.

Key Benefits

Full coverage across networks, web apps, APIs, and cloud environments 
Risk-ranked findings mapped to business impact not just technical severity 
Compliance-ready reports for PCI DSS, ISO 27001, RBI, and SEBI guidelines 
Post-assessment remediation support and re-testing included 
Conducted by certified professionals (CEH, OSCP, CREST) 
Cybersecurity team applying server hardening practices for protection

What We Do

Securiglobe’s Server Hardening service implements security baselines across your Windows 
and Linux servers removing unnecessary services, enforcing least-privilege access, applying 
OS and application patches, and configuring logging and monitoring. We follow CIS 
Benchmarks and NIST guidelines to deliver a hardened, audit-ready server environment.

How It Helps Your Business

An unhardened server is a welcome mat for attackers. Securiglobe’s hardening service removes 
unnecessary risk from your server estate reducing your attack surface and ensuring you 
meet compliance requirements across industries. 

What We Harden

Operating System Configuration

Analysis of the file without executing it file structure, strings, imports, code disassembly, obfuscation techniques, and embedded artefacts

Authentication & Access

Controlled execution in an isolated sandbox environment network connections, file system changes, registry modifications, process injection, and C2 communication

Network Services

Analysis of memory dumps to identify injected code, unpacked malware, running malicious processes, and encryption keys

Audit & Logging

Deep disassembly and decompilation of compiled malware to understand algorithm logic, evasion techniques, and custom capabilities

File System Security

Identification and classification of the malware family, variant, and threat actor attribution where possible

Security Controls

Creation of custom Yara detection rules based on the analysed sample for use in your security tooling

TLS & Cryptography

TLS version enforcement, cipher suite restriction, certificate validity, weak algorithm removal

Our Process

Planning & Objective Setting

We assess your current server configuration against your chosen benchmark (CIS, DISA STIG) and produce a gap report with pass/fail status for each control.

Open Source Intelligence

Not all controls carry equal risk. We prioritise findings by exploitability and impact so your team addresses the most critical gaps first.

Initial Access

We implement approved hardening changes using configuration management tools or direct configuration with full change documentation.

Planning & Objective Setting

After implementation, we test that hardening changes have not broken application functionality and validate the target benchmark score.

Open Source Intelligence

We produce a hardening standard document and configuration baseline record for each server type essential for audit and repeatability.

Initial Access

Optionally, we work with your team to embed the hardened baseline into a golden server image for consistent deployment.

Frequently Asked Questions

Will server hardening break our applications?

No. Our server hardening services are designed to improve security without disrupting legitimate business applications. We test proposed hardening changes against your applications before implementation. If a CIS benchmark control conflicts with a legitimate application requirement, we document the exception and implement an appropriate compensating security control.

Yes. Our server hardening services can be applied across large server environments using automation tools such as Ansible, PowerShell DSC, and other configuration-management technologies. This allows consistent server security hardening across hundreds or thousands of servers while reducing manual intervention and configuration drift.

The core server hardening approach is similar, but cloud environments require additional security controls. Our cloud server hardening process considers areas such as metadata service access, instance-role permissions, identity controls, network exposure, logging, and cloud-provider security features. We apply both OS-level and cloud-layer hardening for cloud virtual machines.

Our server hardening services can include operating system configuration review, unnecessary service removal, secure authentication settings, access-control configuration, network-service restrictions, logging and monitoring, patch configuration, file and permission security, and alignment with relevant CIS benchmarks and security best practices.

Yes. We provide server hardening services in India for Windows, Linux, cloud, and on-premises server environments. Our server security hardening approach is tailored to your infrastructure, applications, operational requirements, and applicable security standards.

Yes. Our Windows server hardening and Linux server hardening services help organizations strengthen operating system configurations, reduce attack surfaces, secure access controls, and address common security misconfigurations. Hardening recommendations are aligned with applicable CIS benchmarks and your organization’s security requirements.
