Tools

Tools to check security hardening

  • Chef InSpec - open-source testing framework by Chef that enables you to specify compliance, security, and other policy requirements. can run on Windows and many Linux distributions.

GNU/Linux

  • Lynis - script to check the configuration of Linux hosts
  • OpenSCAP Base - oscap command line tool
  • SCAP Workbench - GUI for oscap
  • Tiger - The Unix security audit and intrusion detection tool (might be outdated)
  • otseca - Open source security auditing tool to search and dump system configuration. It allows you to generate reports in HTML or RAW-HTML formats.
  • SUDO_KILLER - A tool to identify sudo rules' misconfigurations and vulnerabilities within sudo
  • CIS Benchmarks Audit - bash script which performs tests against your CentOS system to give an indication of whether the running server may comply with the CIS v2.2.0 Benchmarks for CentOS (only CentOS 7 for now)

Windows

  • Microsoft Security Compliance Toolkit 1.0 - set of tools that allows enterprise security administrators to download, analyze, test, edit, and store Microsoft-recommended security configuration baselines for Windows and other Microsoft products
  • Microsoft DSC Environment Analyzer (DSCEA) - simple implementation of PowerShell Desired State Configuration that uses the declarative nature of DSC to scan Windows OS based systems in an environment against a defined reference MOF file and generate compliance reports as to whether systems match the desired configuration
  • HardeningAuditor - Scripts for comparing Microsoft Windows compliance with the Australian ASD 1709 & Office 2016 Hardening Guides
  • PingCastle - Tool to check the security of Active Directory

Network Devices

  • Nipper-ng - to check the configuration of network devices (does not seem to be updated)

TLS/SSL

SSH

  • ssh-audit - SSH server auditing (banner, key exchange, encryption, mac, compression, compatibility, security, etc)

Hardware - CPU - BIOS - UEFI

Docker

  • Docker Bench for Security - script that checks for dozens of common best-practices around deploying Docker containers in production, inspired by the CIS Docker Community Edition Benchmark v1.1.0.

Tools to apply security hardening

GNU/Linux

Windows

  • Microsoft Security Compliance Toolkit 1.0 - set of tools that allows enterprise security administrators to download, analyze, test, edit, and store Microsoft-recommended security configuration baselines for Windows and other Microsoft products
  • Hardentools - for Windows individual users (not corporate environments) at risk, who might want an extra level of security at the price of some usability.
  • Windows 10 Hardening - A collective resource of settings modifications (mostly opt-outs) that attempt to make Windows 10 as private and as secure as possible.
  • Disassembler0 Windows 10 Initial Setup Script - PowerShell script for automation of routine tasks done after fresh installations of Windows 10 / Server 2016 / Server 2019
  • Automated-AD-Setup - A PowerShell script that aims to have a fully configured domain built in under 10 minutes, but also apply security configuration and hardening
  • mackwage/windows_hardening.cmd - Script to perform some hardening of Windows 10
