7. How do local area networks (LANs) differ from metropolitan area network (MAN)? A local area network (LAN) is a group of microcomputers located in the same general area. It covers a clearly defined small area‚ such as an office‚ home network ‚one floor or work area‚ a single building‚ or a group of buildings. While a metropolitan area network (MAN) connects LANs and BNs located in different areas to each other and to WANs. MANs typically span between three and 30 miles. For example a large university

26‚ 2014 Lab #6 Design Your DMZ and LAN-to-WAN Security Solution 1. Describe how creating zones is helpful in the design of a DMZ and security solution for the LAN-to-WAN Domain. The purpose of a DMZ is to add an additional layer of security to an organization’s local area network. An external attacker only has direct access to equipment in the DMZ‚ rather than any other part of the network. 2. How many zones does your design incorporate? Do you think an additional zone may be needed if

LAN/WAN Topology and Configuration Plan Introduction This document presents an overview of the different configuration challenges‚ methods‚ and techniques required to implement a Local Area Network (LAN) and Wide Area Network (WAN). These are useful technologies that securely connect multiple LANs in separate geographical locations. When properly configured these networking technologies provide robust features‚ increased data transfer speeds‚ and secure data connectivity required by today’s companies

Remote Access Remote access • refers to the ability to access a computer‚ such as a home computer or an office network computer‚ from a remote location. • Remote access can be set up using a local area network (LAN)‚ wide area network (WAN) or even a virtual private network (VPN) so that resources and systems can be accessed remotely. • To establish a remote connection‚ both the local machine and the remote computer/server must have remote-access software. Alternatively‚ there are service providers

Project part 1 When developing a multi-layered security plan you need to look at all seven domains of a typical IT infrastructure and check if they need to be increases.one of the weakest link in IT infrastructure In the user domain‚ one of the easiest ways for the system to be compromised is through the users. Simplicity of user’s passwords can be a major problem so we need to implement complex passwords including eight or more characters‚ both upper and lower case‚ and use of at least one special

reviewed your needs and circumstances and have designed a remote access control policy that will work for you and your company. This is a multi-layered security system that consists of the user’s domain. The user is the first and the weakest link in any system. The security is only as strong as the user’s ability to understand what can go wrong. We can implement a training program session for security awareness. Another security measure is to implement a policy to stop employees from bringing in CD’S‚ DVD’S

From: Intern Good day to you and anyone reading this correspondence. I have been tasked by the IT security team to draft a Remote Access Standard to be implemented within the current security infrastructure. Knowing the types of things that could come about from insecure resources I’d like to offer a solution to issues that may come about from using process like VPN and remote access for people that telework into the office from home. Having multiple levels of access controls will help keep this

That means those assets should be you first line of defense. Technical failure and human error are the most common causes of unintentional downtime. Malicious attacks can occur and cause downtime in all seven domains of an IT infrastructure‚ but you are more likely to see them in the User‚ Workstation‚ LAN‚ and WAN domains. Opportunity cost

INTRODUCTION: A local area network (LAN) is a network of computers that interconnects computers in a limited or a small area such as a home‚ computer lab‚ school‚ or office building using the network media. The defining characteristics of LANs‚ is in contrast to the wide area networks (WANs)‚ including their higher data-transfer rates‚ smaller geographic area‚ and lack of a need for leased telecommunication lines. ARCNET‚ Token Ring and other technology standards have been used in the past‚ but

7/12/13 Multi-Layered Security Plan When developing a multi-layered security plan‚ you must look at each of the seven domains of the IT infrastructure and increase security on each of those domains. The seven domains are user domain‚ workstation domain‚ LAN domain‚ LAN to WAN domain‚ WAN domain‚ and remote access domain. Increasing the security on each of those seven domains will increase the overall security of the system and create a multi-layered security plan. In the user domain‚ one of the
