Hardening is to make system hard to protect from unauthorized access and is an on-going process of providing security. Binary hardening is a security technique in which binary files are analyzed and modified to protect against common exploits. Networking Hardening Techniques Once you've recognized threats and vulnerabilities, it's time to start applying security hardware, software, and processes to your network to prevent bad things from happening. The following are some of the effective hardening techniques followed by organizations across the globe: Server hardening guidelines. Device hardening can provide a strong first line of defense. Hardening is a catch-all term for the changes made in configuration, access control, network settings and server environment, including applications, in order to improve the server security and overall security of an organization’s IT infrastructure. Review the links below on device hardening to learn about and enable available security features; Commit to logging and monitoring suspicious activity, so that malicious activity, such as brute-force probing, can be detected early; The best current practices for device hardening and monitoring can be found at the following links: Chapter 4: Network 75. We talked about general network hardening, and now we're going to dive deeper into more specific tools and techniques for hardening a network. Host-based anti-malware products have two components: a security agent that resides on the desktop and a central management server, or host. Hardening IT infrastructure is simply increasing the security posture of virtually all components within the infrastructure, including devices, software, network services and facilities. We'll pay close attention to features and options available on networking infrastructure hardware. Among the infrastructure elements that must be hardened are servers of all kinds, applications, databases and OSes. The details page for the Adaptive Network Hardening recommendations should be applied on internet facing virtual machines recommendation opens with your network VMs grouped into three tabs:. Section 2: Intermediate Server-Hardening Techniques 58. Binary hardening is independent of compilers and involves the entire toolchain.For example, one binary hardening technique is to detect potential buffer overflows and to substitute the existing code with safer code.
