    The first line of defense for almost every organization is typically the system administrator. This is the person that actively interacts with the company network on a daily basis, and by extension has intimate knowledge of it. So it stands to reason that this person would hopefully be the first to notice any signs of possible compromise would it not? Sadly that is often not the case. Whether it is due to a lack of IT Training, complacency, or laziness is anyone’s guess.…

    It 241 Wireless Network Standards

    When it comes to communications, broadcasting signals, and staying within guidelines governed by the FCC and the IEEE here in the United States a system of standards have been developed in order to help the communications and information industry streamline their efforts to work together instead of against each other. Some people feel this is a good practice and conductive toward the progress and growth of technology. Other people feel these standards take away from the freedom of creativity and the ability of companies to produce their own standards and products which may win over popularity with the general public in turn becoming a De-facto standard.…

    Network 320

    First, I have to define the term RFC. The acronym "RFC" stands for "Request for Comment". This refers to a description of a standard for new or modified internet or networking protocols. When standards are proposed, they are made available for public comment so that they can be refined and agreed upon. The document which details the proposed standards is called a "request for comment" document, or RFC. When the standards are finalized, they keep the same "RFC" Three organizations under the Internet Society are responsible for the actual work of standards development and publication: Three organizations under the Internet Society are responsible for the actual work of standards development and publication:name. Now a Request for Comments (RFC) is a publication of the Internet Engineering Task Force (IETF) and the Internet Society, the principal technical development and standards-setting bodies for the Internet. Request for Comments documents were invented by Steve Crocker in 1969 to help record unofficial notes on the development of ARPANET. RFCs have since become official documents of Internet specifications, communications protocols, procedures, and events. Today, it is the official publication channel for the Internet Engineering Task Force (IETF), the Internet Architecture Board (IAB), and — to some extent — the global community of computer network researchers in general. A new model was proposed in 2008, refined, and published in August 2009, splitting the task into several roles, including the RFC Series Advisory Group (RSAG). (The model was updated in 2012. The RFC series contains three sub-series for IETF RFCs. Not all RFCs are standards. Each RFC is assigned a designation with regard to status within the Internet standardization process. This is a partial list of RFCs (request for comments memoranda). I wasn 't aware of how many RFC 's there are, and found to my…

    wireless diffrences

    The Difference between 802.11b,a,g,n wireless LANs is that what frequency band they use and the maximum data rate. Take 802.11a technology it uses the 5 GHz band and can get great speeds up to 54mbps. The problem is that the range on the 802.11a network doesn’t go too far so they developed the 802.11b technology which is 2.4GHz and has max data rates of 11mbps. That’s a huge drop off from 802.11a’s 54mbps but the benefit of this network was the range was a lot better. Next came out was the 802.11g technology which is 2.4GHz and 54mbps this combines the technology of the 802.11b/a networks because it has the range and speed but with the fueling internet speeds and data speeds needed 802.11n technology was created, which has a 2.4GHz or 5GHz network which you can choose which frequency band you want to use or you can use both of them. Another benefit is that it has a max data rate of 450 mbps.…
