Topics Covered Types of Routers External IP Addresses DHCP Server Port Forwarding Firewalls Port Triggering Examples of Multiple Router Configurations Class Notes SOHO Routers are better than residential routers, and easier to use then Enterprise routers Always buy a static IP address if servers on the LAN will provide services to the Internet DHCP is provided by most SOHO routers. Create a DHCP scope that does not include the static IP addresses used by other servers on the network. The DHCP server on a SOHO router can trigger other DHCP servers to turn off Port Forwarding allows you to forward specific types on Internet traffic to specific servers on the LAN Firewalls block ports which can prevent hacking, but can also cause problems for legitimate users

Topics Covered: Defining Hackers Updating Software Antivirus Software Antimalware Software Firewalls Site Advisors Internet Security Suites Web Browser Security Problems Class Notes: Defining Hacker There are many reasons why people hack. Some do it for fun, profit or to prove a point. Hacking is simple enough that a 9 year old can do it. Software Flaws / Updates Are the prime reasons computers are compromised Anti Virus Protects against viruses A virus is self replicating and tries to damage a computer Anti Malware Malware is software that’s primary purpose is not to damage a computer Malware generally tries to collect information about a user, or tries to force a user to visit sites or buy products. Firewall Hardware firewalls are built into routers Software firewalls are installed onto your computer “Security” Suites Security Suites can be worse than hackers — We have met the enemy and he is us.

Site Advisors Warn you if you are going to an “unsafe” site Web Browsers The Problem with Internet Explorer is that is does more than just browse the Internet. Firefox and Chrome are better but still have problems
