  15. Firewall Protection • Keeps hackers from coming in system’s ports the same way your ISP does. Also stops unwanted programs sending information out. • MS Firewall better than nothing, but it protects in-coming only. Sygate or ZoneAlarm are good. Use one only. Not AVG Beta Firewall. • Computer running 7/24 increases the risk. • High-speed increases the risk. • Firewalls identify who wants in and out. If previously approved by you, it passes. If not, you are advised and a decision is needed.

  16. How to Handle Firewall Decisions A Firewall encounters a new request - a program wants to enter or leave computer • You are asked to “Allow” or “Block” an application and if you want to “Remember the Decision”. • For Internet Explorer – Answer “Allow” and “Remember” – because you want it. • For Adobe – I answer “Block” – because they don’t need to know what I am doing and “Remember” because I am sure.

  17. Zone Alarm

  18. How to Handle Firewall DecisionsWhat do I do when I am not sure? • Firewall asks to “Allow” or “Block”, a program called “Whatsrunning”. • You want to see if you can “Block” it and still operate normally. • Answer “Block” but don’t ask to “Remember” yet. • See if you operate the same. • If you operate the same, the next rime answer “Block” and “Remember.”

  19. Zone Alarm

  20. Reset your Firewall You may have made a wrong decision Remove all “Allow” and “Block” decisions that you have in your firewall. • Then every time you encounter an application you will be asked to “Allow” or “Block” and to “Remember”. NOTE: Firewalls can block programs and services that you need. When system is running OK, note which programs are allowed and blocked.
