dq1: This week you will examine WireShark, a well-used network-packet analyzer. For this discussion:Define a packet analyzer and describe its useList commonly used packet analyzers (beyond WireShark)List best practices for analyzing packetsDescribe uses (good and bad, ie. hacker) of a packetanalyzerDiscuss ways you would protect your own network data from being analyzeddq2:One of the first lines of security defense that companies (and individuals) should perform is to enable a firewall. Today, most routers include a firewall, most personal-computer operating systems provide a firewall, and their are a variety of network (hardware and software) firewalls available. For this discussion:Define the term firewallDiscuss the goal(s) of a firewallDescribe different types of firewalls (router, server, personal computer, network) and when users should use eachList several commonly available (open source) firewallsDescribe best practices for using a firewallMake sure you post your primary response and then respond dq3:One of the ways businesses provide secure access to their network (or a subset of their network) to remote (or mobile) users is to use virtual private networks (VPNs). VPNs allow users to connect securely (over an encrypted link) to a network. For this discussion:Define the term virtual private networkDiscuss the goal(s) of a VPNDescribe different types of VPNs (hardware or software based)Discuss how the use of a VPN may support BYOD (bring your own device)List several commonly available (open source) VPNsDescribe best practices for using a VPNdq4:Security is a very complex process, affecting applications, networks, databases, facilities, and more. This week we will examine security considerations. Specifically, I am looking for you to provide simple best practices all users (and companies) should follow.
