You Decide – Assignment 1 SEC572 – Week 2 To develop network security strategies that will ensure that the organization’s network is protected from both internal and external security risks. A summary of the steps I can take to mitigate the risk in the following areas: Denial-of-Service attacks (DoS)‚ Distributed Denial-of-Service attacks (DDoS)‚ Masquerading and IP Spoofing‚ Smurf attacks‚ Land.c attacks‚ Man-in-the-Middle attacks. Denial-of-service DoS attacks DoS attack is simply to send

4 OSI Transport Layer 4.1 Roles of transport Layer 4.1.1 Purpose The Transport layer provides for the segmentation of data and the control necessary to reassemble these pieces into the various communication streams. Its primary responsibilities to accomplish this are: Tracking the individual communication between applications on the source and destination hosts Segmenting data and managing each piece Reassembling the segments into streams of application data Identifying the different applications

The acknowledgment number is set to one more than the received sequence number‚ and the sequence number that the server chooses for the packet is another random number. c. ACK: Finally‚ the client sends an ACK back to the server. The sequence number is set to the received acknowledgement value‚ and the acknowledgement number is

D6T thermal sensor and People Counting Algorithm In this thesis work‚ a new indoor people counting algorithm is created by using Omron D-6T thermal sensor and Raspberry Pi. The sensor periodically generate thermal map of heat emitted in its field of view which is a one dimension array and pass the array to Raspberry for further processing. The people counting algorithm is created in Raspberry Pi by processing thermal map generated by D6T. After processing the number of people indoor is obtained

It all started when Zack’s parents got into a fight and Zack got all stressed out and decided to take a leisurely walk in a nearby forest. As he was walking in the forest‚ he would yell‚ shout and holler hurtful words about himself and how it was his fault that his parents were fighting. Consumed with anger‚ Zack was unaware of the distance he was walking. When he realized he was lost‚ it was too late. When Zack was trying to recall where he came from‚ it started to rain. Zack burst into tears. He

| | IntroductionThe term “computer network’’ means a collection of autonomous computers interconnected by a single technology. Two computers are said to be interconnected if they are able to exchange information. The connection need not be via a copper wire; fiber optics‚ microwaves‚ infrared‚ and communication satellites can also be used. Networks come in many sizes‚ shapes and forms. Uses of Computer Networks 1. Business Applications 2. Home Applications 3. Mobile Users 4. Social Issues
