Security Analysis and Redesign of a Network Coursework

Security Analysis and Redesign of a Network - Coursework Example The coursework "Security Analysis and Redesign of a Network" presents the review of the current network infrastructure of the XYZ company. The paper proposes, both theoretically and diagrammatically/graphically, a redesign of this network, offers recommendations for how or better procedures that the organization can harden both its Apache, and it IIS web servers. Further, the report presents a security policy write-up, which will guide the organization with regards to spyware, antivirus, and adware policies. Both active and passive reconnaissance was carried out on A2Z’s computers and networks, in an attempt to gather more information and find whether any open ports existed. This also enabled determine the vulnerabilities of the system so as to ensure that any existing vulnerabilities are taken care of before they are exploited by attackers. This was done using one of the most powerful network scanning tools, Nmap. Several interesting ports, including XYZDomainController at 192.168.0.1, XYZInviteDesign at 192.168.0.2, XYZ Acct at 192.160.0.3, XYZprinting at 192.168.0.4, XYZwebsrv at 192.169.0.5, and XYZChat at 192.168.0.6, were scanned. It is clear from the Nmap port scan results that XYZ’ s network server configuration is now is, is somewhat vulnerable. For instance, port 445 is set to open, which is very risky and is a vulnerability. This port, port 445, an MB port over IP is constantly being scanned by hackers, and if left open, they can easily gain remote access to the network.
