A process of hardening provides a standard for device functionality and security. System Hardening vs. System Patching. Hardening is an integral part of information security and comprises the principles of deter, deny, delay and detection (and hardening covers the first three). The SANS Institute is a partner in the Critical Security Controls project to define the most important tasks for network security. Introduction Purpose Security is complex and constantly changing. Failure to secure any one component can compromise the system. This standard was written to provide a minimum standard for the baseline of Window Server Security and to help Administrators avoid some of the common configuration flaws that could leave systems more exposed. System hardening will occur if a new system, program, appliance, or any other device is implemented into an environment. If you ever want to make something nearly impenetrable this is where you'd start. Systems hardening is a collection of tools, techniques, and best practices to reduce vulnerability in technology applications, systems, infrastructure, firmware, and other areas. I'm fairly new to this area, but I'm researching OpenSCAP and OpenVAS . Hardening system components To harden system components, you change configurations to reduce the risk of a successful attack. I'd like to write about how to use a tool to automatically scan a system per some guidelines or vulnerability database. System hardening is the process of securing systems in order to reduce their attack surface. Organizations should ensure that the server operating system is deployed, configured, and managed to meet the security requirements of the organization. Most commonly available servers operate on a general-purpose operating system. The DoD developed STIGs, or hardening guidelines, for the most common components comprising agency systems. The link below is a list of all their current guides, this includes guides for Macs, Windows, Cisco, and many others. The first step in securing a server is securing the underlying operating system. As of this writing, there are nearly 600 STIGs, each of which may comprise hundreds of security checks specific to the component being hardened. Attackers look for a way in, and look for vulnerabilities in exposed parts of the system. Operational security hardening items MFA for Privileged accounts . When we want to strengthen the security of the system, we we need to follow some basic guidelines. Secure installation It is strongly recommended that Windows 10 be installed fresh on a system. Use dual factor authentication for privileged accounts, such as domain admin accounts, but also critical accounts (but also accounts having the SeDebug right). new or upgraded operating system installations based on best security practices in conjunction with system prepar ation guidelines set by one s comp any. Different tools and techniques can be used to perform system hardening. 1.3. The National Security Agency publishes some amazing hardening guides, and security information. Guidelines for System Hardening This chapter of the ISM provides guidance on system hardening. The process o f loading an operating system and then har dening a system seem ed to be 2 independent and time -consumin g oper ations For hardening or locking down an operating system (OS) we first start with security baseline. First, let’s revisit STIG basics. Surveillance systems can involve 100s or even 1000s of components.
