Network Security is most important concerns with concept of designing and managing a secured network and information security in any enterprise or organization management efficiently. Secure a network mainly involves applying policies and procedures to protect from unauthorized access. This paperwork demonstrates the tasks needed to enhance the network security using in Linux environment. And also this paperwork describes the importance open source software linux policies for secure the information. The Linux is open source software can get software upgrades directly from internet. This research project explores the key role of Linux configurations that the server an easy target to hackers over the internet. By following industry best practices by some security configurations, a Linux Server can be well secured. This research project explores and suggests best practices for the general hardening for common Linux security services such as Proxy server, Apache Web Server, and firewall (IPTABLES) to block connections to unwanted ports and blocking bad traffic and minimize unauthorized access and maximize security, privacy and access protection of organization network.
