For the umpteenth time, I put my fingers to work on the keyboard so as to wearily answer questions, from some moronic groups, about the need for a
firewall security system in their PCs. Not all computer users have brains that function normally. We have many scumbags out there who use their technical knowledge in wreaking havoc and distress to other networks. Now, we can't blame these foul, vile, and twisted guys because their brains are so rotten that they can't think of anything worthwhile to do with their time. The only thing that we can do is to prevent them from accessing our networks and routers.
Our router is the thing responsible for everything that exists in the Internet. It sends the e-mails, files, pictures, and attachments to the recipient's address. It ensures that the packet reaches its destination and not wander around someone else's mail. This is the reason why so many hackers, spyware authors, identity thieves, and virus writers are very interested in accessing your router to get all the important information about the user including the
IP addresses of important people stored in his system. Thus, there is need for a software or hardware firewall that can provide stateful packet filtering and can block unwanted programs from penetrating your system and accessing the Internet.
