Remote networks just utilize a link to unite the network by means of a modem to the Internet Service Provider over phone lines to the Internet. Equipment The equipment expected to effectively set up the LAN networks at every area are a switch/firewall mix‚ a modem‚ remote network interface cards for every workstation‚ and the cabling important to associate the switch to the modem and the modem to the Internet to secure the WAN association. Servers and their arrangement additionally have influence

When developing a secure network‚ the following need to be considered: 1. Access – authorized users are provided the means to communicate to and from a particular network. 2. Confidentiality – Information in the network remains private 3. Authentication – Ensure the users of the network are who they say they are. 4. Integrity – Ensure the message has not been modified in transit. 5. Non repudiation – Ensure the user does not refute that he used the network. IV. PV4 AND IPV6 ARCHITECTURES IPv4 Architecture

As part of the network security team‚ we will be proving IDI with a network security plan to mitigate the vulnerabilities that have been discovered. A secure site will be set up with network intrusion detection and network protection systems will be available to access via the internal network. Policies will be presented for remote access and the use of VPN. Also contained within this report will be strategies for hardening the network and mitigating risks.

________________________________________________________________ Overview In this lab‚ you secured a Linux server system. You secured the bootloader‚ enabled iptables firewall‚ and ran SELinux to help lock down the Linux OS. By securing the bootloader‚ you prevented access to single-user mode and the GRUB Console during the boot of the system. Enabling iptables and applying firewall rules ensured that only the applications you wanted can reach or reach out from your computer. You also applied access control lists (ACLs) to
