ERNW Hardening Repository

Today we started publishing several of our hardening documents to a dedicated GitHub repository — and we’re quite excited about it! It took a while to develop a suitable markdown template to support all the requirements you have when you write a hardening guide, but we’re online now!

At the moment, only a few hardening guides are online, but that should continuously increase in the future.

Click here for the GitHub ERNW Hardening Repository!

Cheers,

Internet Information Service 7.5 Hardening Guide

Internet Information Services (IIS) contains several components that perform important functions for the application and Web server roles in Windows Server. As it is designed to be used in an enterprise environment, the security of this system must be kept at a high level.

By default IIS implements a lot of basic security measures, but are these the relevant ones to protect your business? Continue reading “Internet Information Service 7.5 Hardening Guide”

IPv6 Hardening Guide for Linux Servers

We were recently approached by a customer asking us for support along the lines of “do you have any recommendations as for strict hardening of IPv6 parameters on Linux systems?”. It turned out that the systems in question process quite sensitive data and are located in certain, not too big network segments with very high security requirements.

Tomcat 7 Hardening Guide

Hi,

continuing our tradition from last year (see here and here), we summarized more of our hardening recommendations for you. This guide is covering Tomcat 7 and is supposed to provide a solid base of hardening measures. It includes configuration examples and all necessary commands for each control, specifically for the most recent branch of Tomcat as there were some significant changes.

Have a good one,

SLES 11 Hardening Guide

SUSE Linux Enterprise Server (SLES) has been around since 2000. As it is designed to be used in an enterprise environment the security of these systems must be kept at a high level. SLES implements a lot of basic security measures that are common in most Linux systems, but are these enough to protect your business? We think that with a little effort you can raise the security of your SLES installation a lot.

We have compiled the most relevant security settings in a SLES 11 hardening guide for you. The guide is supposed to provide a solid base of hardening measures. It includes configuration examples and all necessary commands for each measure. We have split the measures into three categories: Authentication, System Security and Network Security. These are the relevant parts to look for when hardening a system. The hardening guide also includes lists of default services that will help to decide which services to turn off, which is an essential step to minimize the attack surface of your system.

See all of the steps that we compiled for you in our hardening guide for SLES 11: ERNW_Checklist_SLES11_Hardening.pdf
