Well, let me begin by saying that router configuration is not to be taken on by the faint of heart. If you are a novice user, please seek professional help now! I am far from being considered a novice, and I have found the task to be daunting.
It is unusual for a programmer to find themselves dabbling in the security features, but this is where my job has taken me. I have the task of securing an entire branch from the attacks on the outside and the carelessness of the users. I have to speak for my users at this point. It is not an intentional carelessness, but a product of assuming that I can fix anything, which is for the most part true. I am impressive. Yet, they do seem to test my ability to keep them safe!
I began a general search on Google (remember that Google will save every search and page click for the rest of time). I thought a general information search concerning firewall setup should do the trick to get my feet wet beyond the standard port in and outs.
I came across some fantastic links:
Gibson Research – great tools and information
Steve Gibson – blog
I discovered Cisco’s Safe Reference Guide, but I do not know if I am ready just yet to dive into this much complexity. Our network is small and requires quite a bit of freedoms from the inside. I am mostly concerned with the outside getting inside. I am linking, but choosing not to spend endless hours weeding for useful fruits just yet.
I found this – What is a Firewall? Well, I approached this with a bit of a big head, but I soon realized that finding information on my hard firewall was going to be much more difficult than the typical soft firewall that I was accustomed too. If you don’t understand the difference between a hardware and software firewall, you need to make the trip to the Portforward site and read this article.
I discovered a neat tool. Probe My Ports This truly makes Gibson Research my new friend of the week.
I haven’t gotten any closer to securing this branch, but I have equipped myself with a worthy read for the week, including many sites. I am looking forward to reading Steve Gibson’s blog even though it is incomplete and more than likely forgotten.
I will let you know what I come across more on this topic worth noting.
A computer lets you make more mistakes faster than any invention in human history – with the possible exceptions of handguns and tequila ….
