Linux Server Hardening


Defining and implementing a comprehensive server security policy is an essential step in the process of securing both Windows and Linux servers.  Server security compliance requirements can no longer be brushed aside, or addressed via a simple, periodic “check the box” exercise. Compliance must be attained and maintained through a set of evolving, continuously implemented, and easily-audited controls. The organization that doesn’t treat compliance as a critical process will struggle through audits and will be vulnerable to attacks.

A good server security posture requires well-defined policies that mitigate business risks – and their enforcement by the IT department. There are numerous guidelines and regulations to help the enterprise mitigate cyber risks to servers, including ISO/IEC 27002, the NIST Cybersecurity Framework, HIPAA, PCI-DSS, and CIS security controls. Server administrators are responsible for creating, updating, and continuously enforcing an extensive, complex set of rules designed to maintain compliance with internal policies and regulatory mandates. The goal – to ensure that enterprise servers support the business by providing uptime and application functionality while remaining as secure and risks- free as possible.

IT network infrastructures are growing in size and complexity – as servers migrate to public/private clouds.  Gaining visibility into server security configurations, assessing the impact of changes, and then implementing them is not only time consuming – but it can also impact business operations in the event of an error.

So it’s not difficult to understand why some IT departments attempt to reduce the scope of the project – either by implementing a less robust policy or by designating large sections of the network as “exception areas”.

The challenge of implementing a secure configuration baseline has never been greater.

THE solutions

CalCom Hardening Solution (CHS) helps enterprises comply with regulatory and organizational requirements – offering powerful hardening automation solutions, centralized security policy management, and change management capabilities to ensure continuous compliance.

CHS automates the labor-intensive task of security-policy testing.  It learns the current security configuration and status of each server and then notifies regarding the impact of any policy change on production environments.  Using CHS, the policy implementation process becomes a one-time effort.  From that point on, CHS automatically re-hardens servers following any unauthorized change – in real-time – ensuring continuous compliance with security policies.

CalCom’s CHS is a must-have solution for any enterprise seeking to quickly and cost-effectively implement and maintain extensive, robust server security policies.
