Tarlogic Hardening Services provides operating system and service configuration security reviews for servers and user workstations. The service begins with local or physical access to the target asset and performs comprehensive analysis of operating system configurations and services to identify weaknesses and improvement opportunities. The review process includes privilege escalation testing when initial credentials lack administrator permissions, aiming to achieve white box review access. The team examines security settings, identifies vulnerabilities, and provides detailed reports with recommended security configurations for each service. The service follows hardening guides from organizations including CIS (Center of Internet Security), NIST (National Institute of Standards and Technology), National Cryptologic Center, and manufacturer-specific guidance from Microsoft, Canonical, RedHat, and Suse. Analysis methodologies incorporate MITRE ATT&CK framework. Reviews cover security policy implementation, privilege delimitation for users, groups, and roles, and service configuration including Active Directory, LDAP, password fortification, firewall, and DMZ configurations. The service provides detailed guidance to asset teams on implementing security enhancements and protections, with the goal of creating configuration models that can be deployed across multiple systems.
