Until I worked at my job I never understood how companies needed a disaster recovery plan. I remember the first time I heard about it, after I became a Team Lead and I sat there confused. It blew my mind because I thought this was a little farfetched to think that anything that catastrophic could happen. But over the years we have experienced a small earthquake and a bomb threat and it started to make sense why it is needed. Like most other companies we can’t afford to have much down time because it would greatly affect our clients and they don’t pay us to be down. Part of our DRP is if the building falls down we could potentially have to go out of state to continue working which would not be a good thing. Nobody wants to go out of state to go and work, just because we would not know for how long we would need to stay.
We also talked about social engineering and it made me look up more information about what types of social engineering there are out there. From phishing to pretexting and piggybacking, the fact that people do this is disgusting, what gives them the right to steal from innocent people. Everyone should educate themselves on how to avoid this, there have been many stories of people losing money and losing their identities because they don’t know any better. Other forms of what I mentioned are phone calls, people will call someone up and pretend to be the IRS and tell them that they need to pay or get in trouble with the IRS. People who do not know will panic and pay, not realizing that the IRS will not ever call you they will only send official mail. This class has really helped me understand how I need to protect myself and what steps I can take.
This week was another eye-opening week for me. This week felt exactly like the first time you got to see the image within a 3D stereogram if you don’t remember (I’ll try to add one here) those were the pictures that you had to stare at until you got to see the image. Anywho that is how this week felt when I was writing and reading about network segmentation. When I was reading about it, it was kind of making sense but I wasn’t fully understanding, not until they showed a picture of a 10 port switch. Earlier in the article, it mentioned how you should separate devices onto a single broadcast to avoid broadcast traffic. But when I saw the ports and how you can connect each device to each port, that is when it all clicked and I finally understood what it meant. It was a great feeling, to be honest, and maybe not everyone will share my enthusiasm but I really enjoyed it.
The best part of this class has been how we are forced to think about things that we do not normally think about, and I do not mean that in a bad way. For example, this week we for our discussion board question we got to look at how cell phones transmit data. I never thought about it, all I knew was you type a text and hit send, but how does that information actually get there. So, it was real interesting to find out how all of this is being sent via small packets of information. Or how your voice gets converted into an signal and replayed for the person on the other end of the phone. I also found out about something called WiMax and how great they were before they folded and could no longer compete in the cell phone transmission world. They could have actually been a great company and maybe even the leading technology in how fast phone information is processed, from the LTE’s to 4G connection or whatever other fancy name they want to put on cell phone connections. Each week it just keeps getting better with what we are learning.
This week we learned about IPv6 and the reason why it was created. I never realized that the internet would ever run out of IP addresses. I always figured that IP addresses were recycled, but when you think about it logically they would never do that because of the illegal activities that criminals conduct. The IPv4 has been around forever and a day but the main problem was that IP addresses for IPv4 was starting to run out of addresses so the solution was the IPv6. The IPv4 was a 32-bit address but with the IPv6 it changed to 128-bit address, with this change it will allow up to 4 million different addresses to be used. This should solve the problem for a very long time before the computer wizards figure out a way to resolve that issue once the 4 million starts to run out. I can’t imagine anyone being able to remember the new format of an IP address and actually enter it in. Awesome week.
This week was an exciting one; I picked a topic that was a little challenging but rewarding at the same time. This week for a homework assignment, I picked to write about proxy servers, little did I know there were so many different types of proxies. I have heard of some of them like the SSL, HTTP, and VPN but the Socks and the Anonymous one is not ones that I have heard of before. In fact, as I wrote about in my paper, I deal with VPN every day; the term we use at my job is Pulse. In order to log into our application, we need to “Pulse” in every morning since our main servers are located in another state. Once we do that, we have access to everything and are able to go about our business for the day. This week was also another eye-opening one, where I never realized how much stuff goes on behind the scenes and how fast this information is processed.
This was another great week in class. My favorite part was learning about name resolution. I never realized everything that goes on behind the scenes. When I type in a website I never thought that it needed some sort of different address to locate the site. It makes, even more, sense that after you find a website usually every time after it becomes faster to reach that site. These are the things that you never think about when surfing the internet. Also to find out that there is more than one way to search for the ip address, from using FDQN which is an out of date method, because it would be silly to try and remember the 10 digit ip address instead of just the name of the website. It amazes me how the internet is almost perfect, which is so different from everything else in this world. Much like the name resolution and how there are several different ways of getting the same information. Great week.
This was probably the best week so far, at least in regards to what we learned. Doing the powerpoint presentation was very beneficial. Not just in terms of learning the different types of routers that are available, but also learning what you can and cannot do within powerpoint. Now back to the routers, I never realized how many different kinds of routers there are on the market. From home routers to small business routers and everything in-between. I learned how important speed is, which should have been obvious but you don’t really think about these things until you have to. Also found out that when looking for a router one feature that you should look for is 802.11ac which is 3 times faster than anything before it. Now I have more ammunition when I need to buy a new router for my house.
