...G. Angel Bautista Professor Abernathy IT 255 20Apr2012 Security is a fundamental aspect of any network infrastructure. The goal is to always have the most up to date programs and protocols to ensure the protection of the network. No aspect is too small to over look. That could mean the difference between a secure network and a compromised network. The best way to achieve this is to break down every level and approach each one as a separate entity and secure it. Then you can modify it to suit the needs of your network. We can start with the Application layer. The Application layer provides the interface to the user. First the end user should be subjected to a background check to ensure against any potential malicious or questionable acts in the users past. Then the end user should be properly trained in the use of the computer and the proper protocols to access the network. Updates should be made frequently to keep the user up to date. When the user is in the network, make sure that any unnecessary devices, USB ports and any back doors are disabled. You also want to make sure that all files and emails and downloadable attachments are all thoroughly scanned prior to downloading. Finally, be sure to ensure content filtering, and restrict the end user to only what pertains to their primary function. The Presentation layer is responsible for encoding and decoding data that is passed from the application layer to another station on the internetwork. You must first ensure that...

...Multi Layered Security Plan Richman Investments This Multi layered security plan will give you a brief overview of the security strategies that will be implemented at each level of the companies IT infrastructure. The usage of security awareness training to instruct employees of Richman Investments security policies, auditing of user activity will be implemented at the User Domain level of the infrastructure. The usage of antivirus and anti malware programs on each user computer, strict access privileges to corporate data and the deactivation of media ports will be put in place at the Workstation Domain of the infrastructure. Utilizing network switches, encryption to wireless access points using WPA 2 security shell encryption, as well as securing server rooms from unauthorized access will be implemented at the LAN Domain level of the infrastructure. The closing off unused ports using a firewall to reduce the chance of unwanted network access, monitoring inbound IP traffic, more specifically looking for inbound transmissions that show signs of malicious intent, running all networking hardware with up to date security patches, and operating systems with be set in place within the LAN to WAN Domain structure. Enforcing encryption, and Virtual Private Network (VPN) tunneling for remote connections, configuring routers, and network firewalls to block ping requests to reduce chance of denial of service (DOS) attacks, enforcing anti virus scanning of email attachments, Isolating malicious...

...Brian Gobrecht IT255 Project Part 1 The domains of an infrastructure are broken down into several parts. The User, Workstation, LAN, LAN-to-Wan, Remote Access, Wan, and System/Application domains. All of these are a very crucial part of a domain structure and if one fails to do its proper job most of it or all of it will come to a screeching halt. The User Domain is pretty self-explanatory yes a system can do without a user but by itself it’s more probable to breakdowns and other things to go wrong. So to help the user out in a way it’s not damaging to the infrastructure. One way is to have the computer scan for viruses in anything that plugs into the usb slot such as a portable hard drive or a memory card. As for unauthorized downloads such as music or photos I suggest enable content filtering. Workstation domains are another vital part of keeping the system healthy at most times. To protect this I suggest either at the door of the server room keycards to get in and at the workstation itself both a physical and pass worded approach to ensure the right person is getting in. And to add further measure of security the room would be camera surveyed and users will be logged. A LAN domain can be a very volatile domain with all the wiring and NIC cards and LAN switches common in most rooms. If we are to hopefully secure this part of the domain I would like to be able to restrict access to the computers and laptops that are only necessary to the work environment. So if someone...
