...R17. What is the difference between a permanent address and a care-of address? Who assigns a care-of address? Answer: A permanent address is the home address and care of address is the given address of the device such as mobile. Permanent address is where mobile devices live. Care of address is given to the mobile device by the foreign agent when a device entire to another network area. Permanent address will get all the derive data and then the home agent forward data/messages onto the other network via the care of address. After that mobile device directly responds to the correspondent. R1. What are the differences between message confidentiality and message integrity? Can you have confidentiality without integrity? Can you have integrity without confidentiality? Justify your answer. Answer: Confidentiality is the property that the original plaintext message cannot be determined by an attacker who intercepts the cipher text-encryption of the original plaintext message. Message integrity is the property that the receiver can detect whether the message sent (whether encrypted or not) was altered in transit. The two are thus different concepts, and one can have one without the other. An encrypted message that is altered in transmit may still be confidential but will not have message integrity if the error is undetected. Similarly, a message that is altered in transit (and detected) could have been sent in plaintext and thus would not be confidential Message confidentiality...

...Having a secure WLAN is very important, I would even go to say more important than a normal LAN. One way to secure a WLAN is to use encryption. This uses a key that will encrypt and decrypt data on the WLAN so only people what the key would be able to connect to the network. The encryption needs to be strong or a sniffer will crack the key so using a WPA2 would be best. Another way would be to simple change the SSID or ESSID. The reason this is a good way to secure a WLAN is because in most cases if you didn’t change the SSID a hack would think that you didn’t do anything to your network, making it easier to hack. “Though knowing the SSID does not allow anyone to break into your network, it usually indicates that the person hasn't taken any steps to protect their network, thus these networks are the most common targets” ("How to secure," 2007). The ramification of your WLAN being breached could be many things. The first thing I can think of is data theft and by that personal or secret information if someone can get on your WLAN. Also they could be trying to disrupt your network to cause damage or just want to ride on your wireless to gain access to the Internet. I think that stolen information would be the biggest threat.

...Source Address | Destination | Payload | Week 3 The Network Intrusion Detection Engine Network based IDS engines process a stream of time sequential TCP/IP packets to determine a sequence of patterns. Patterns are also known as signatures. Most network signatures are based on the contents of the packets (Packet Content Signature = Payload of a packet). Patterns are also detectable in the header and flow of the traffic, relieving the need for looking into packets. Operational Concept Two primary operational modes 1. Tip off - Look for something new, something not previously classified. 2. Surveillance - Look for patterns from "targets" Forensic work bench * Same tool as in surveillance * Monitor online transactions * track network growth - PCs; mobile devices * System services usage * Identify unexpected changes in the network Benefits of a Network IDS 1. Outsider Deterrence - Make life hard for the hackers 2. Detection - Deterministic; Stochastic 3. Automated Response and Notification - Notifications(email, SNMP, pager, onscreen, audible) Response: Reconfigure router/firewalls; Doing a counter attack is not smart; Lose the connection. Challenges for network based technologies 1. Packet reassembly - Broken packets might not be enough detection. Pattern broken into different packets. 2. High Speed Networks - Flooding and dropping of packets 3. Anti Sniff (Sniffer Detection) - Designed by hackers to detect IDS. Find...

...become part of the dialogue. The internet has created a new form of interactive communication that has lessened the cost of communication across social distances. These networks (PENS or Public Electronic Networks) are intended to promote more interaction between community members while expanding the exchange of ideas in the community. The information exchange between socially distant groups can now take place without face to face interaction, and the discourse is controlled in the interactive forum rather than subject to the stereotypes and biases face to face interaction may harbor. By shrinking the physical distance of all groups involved the PEN network Santa Monica, CA allowed for separate ideas to become part of a singular goal creating a stronger awareness of their issues and more focused community structure. The PEN of Taos, New Mexico built upon this structure by purposely creating an environment that would put community members in direct face to face communication with each while also using the digital medium to augment and facilitate the dialogue. The PEN of Santa Monica was created to aid in raising awareness for the significant homeless population living in the area by providing a new medium for discourse that would allow all parties to be represented. The greater the social distance between two individuals or groups, the less likely they are to communicate and less effective any communication that occurs will be productive. This online community was a combination of...

...Background Paper submitted to the Committee on India: Vision 2020 Telecom Sector in India: Vision 2020 Manas Bhattacharya*, IES (Deputy Director General (Finance), Department of Telecommunications, Ministry of Communications & IT, Government of India) The views exposed in this paper are that of the authors not of the Planning Commission Telecom Sector in India: Vision 2020 by Manas Bhattacharya*, IES (Deputy Director General (Finance), Department of Telecommunications, Ministry of Communications & IT, Government of India) Introduction The purpose of this paper is to construct a vision of Indian telecom sector for the year 2020, i.e., about two decades from now. Development being a continuous process, the choice of the year 2020 is just an arbitrary division of time, a pre-defined time horizon to take stock of what is likely to be achieved. Pre-portrayal of a stage of development in future requires understanding of the process of change, the dynamics that set law of motion. In attempting to do so, the present paper deciphers the recent past. Process of change is often volatile and responsive to intervention and global circumstances impacting it. In such an inherently dynamic situation it is convenient to assume that cross-country experiences incubate the most recent seeds of change. This is because countries at various stages of development encapsulate developmental experiences that occur with the passage of time. The present paper isolates...

...When tele-medical agents return to a medical health information exchange TMH where Internet is available, the collected local information will be forwarded to a web-based multi-specialty telemedicine service. Appropriate returning messages will be routed to local providers through physical delivery to ensure information integrity. Phone calls or text messaging will be used only during a medical emergency. With lessons learned from this field study, we will establish a workable model of health information exchange and telemedicine to connect rural patients with medical services available only in the cities. A medical imaging system is used in the telemedicine system for capturing wound images of a patient’s skin. The practice of tele-dermatology requires high resolution and properly illuminated color images and video. Choosing appropriate wound image quality for telemedicine is important to ensure accurate diagnoses on the part of the clinicians, while keeping network traffic down. Telemedicine systems are broadly categories in two type’s i.e. real-time telemedicine system and store-and-forward approach respectively. In the real-time mode, the clinician is present during the capture process through a videoconferencing system and streaming live data can be send to TMH. The store-and-forward approach in telemedicine system consists of a tele-medical agent capturing patient...
