Building Secure networks in Linux

Project Scenario Wear-IT-On is a department store chain which is evolving in textile market due to its trend setter clothing products. The company has recently decided to host a web server in their network to account for an online shopping portal in order to cater increased demand for products and to strengthen its market. The company deployed a flexible, popular and open source http server - Apache 2.0, which can also make use of server side scripting tools so as to facilitate dynamic web contents, on a CentOS Linux Server. The implementation was carried out by a system administrator trainee who had a very little understanding about server and network security. As part of testing he connected the web server to the internet and after a few days of monitoring he noticed that someone from a trusted IP address has been conducting TCP scans on the network. So the company is worried that someone might be planning to attack the web server in the near future. As a senior network systems administrator, your task is to propose a secure solution by implementing and configuring appropriate security tools so as to secure the server and network from potentially malicious activities. The company’s CIO requires your solution design to cover below requirements:  Implementing HTTPs and restricting access to the website only on port 443  Identifying at least 12 possible threats towards the Apache 2.0, CentOS Linux Server and providing solutions to those threats.  Protecting the network by implementing security methods such as Firewall, IDS/Greynet and Honeypot solutions  Including at least one test machine in your design to be able to test your security design.
