Network Security Requirements
With security mechanisms for the new network, management has asked for a report describing how the basics of a network operate and how two nodes communicate. With this we are going to break down the OSI model (Open Systems Interconnection) which is seven layers along with the TCP/IP (Transmission Control Protocol/Internet Protocol). After this the management team will know the difference between the two models along with some other key information. OSI
With OSI (Open Systems Interconnection) was developed to help standardize networking. The OSI model has been an element of computer network design since the early 1980’s. With the OSI model it shows how the network protocols and equipment should communicate and work together as one. With the OSI as a standard with in ISO (International Standards Organization) todays current technology does not always conform to the standard of the ISO, but it …show more content…
Applications that use the Internet can have weaknesses when it comes to updates. Usually vendors will release patches to address some of these weaknesses when they are discovered. For some reason the full patch is not installed this now makes the application vulnerable. When the user downloads a document, media file, or even just a HTML page on this un-patched system the system can be compromised. With this happening this can cause more malware to be downloaded making the overall system worse. With the IPS in place the patches with the vulnerable application can be scanned by network traffic for patterns with the IPS it will help you will data about the network on a regular basis to see what is going on. With the IPS in place we will have the control to set it up with all the policy’s that are needed to help fight against any
