DEPLOYMENT AND UPDATE OF A NETWORK'S SECURITY INFRASTRUCTURE

This article stresses the importance of security for computer networks within organizations and shows the results obtained from a security infrastructure update at a particular company. The updating process included improvements to the initial design (in terms of both hardware and software) for various company branches around the country. A new firewall is implemented at the company's industrial facilities and a site-to-site VPN is created for communication with the main headquarters. Due to the malfunction of the addressing scheme and also to the change of ISP, full firewall integration is deployed together with static route reconfiguration. The academic value of the present work is to offer key guidelines for any implementation as well a providing the reader with information-security and firewall-associated concepts.
