Nt1330 Unit 3 Assignment 1 Case Study

1.3 Discussion Questions 1. Does a network interface on a sniffer machine require an IP Address? -No, the sniffer doesn't require an IP address, it wants to remain invisible to the other machines in order to intercept messages undetected. 2. In what mode does a sniffer’s network interface operate?

1. List and explain the top 5 factors that are required, at a bare minimum, to make an application secure. Security architecture, authentication, session management, access control, and input validation are the top five factors that make an application secure. Security architecture: OWASP verification requirements in security architecture verify all the application components and libraries that are present in the application are identified. A high level architecture of an application must be designed.

BU275 Assignment 2 Equations Question 1 A Station 1: Prep Inter-arrival time is the time between consecutive arrivals of the customers. Because the inter-arrival times are exponentially distributed, customers arrive at random times. The mean is 100 customers/ hours. This indicates that a customer arrives every 0.6 minutes.

Hi, Todd, how do you do? I hope my message finds you well. Regarding your request, we - GI_SSC_OM_S1 and GI_SSC_MFGPTS_S1 squads - only will be able to answer the Security and Risk questionnaire after we access the environment of our clients, that only will occur when Chris Maurer validates the data we sent to him from application owners and he informs us how we must to procede to start the access procedures without violate the export regulations rules from IBM. As we only receive part of the list that we sent to application owners (AO) yet, we have two situations right now: some data still under verification by AO and others under validation of Chris, as the graph bellow: Our PO and SLL are aware of this situation.

Chapter 2 Security and Encryption Introduction the process of preventing and detecting unauthorized using of your computer is called Computer security, prevention help to stop unauthorized users (also known as "intruder") from accessing computer system, detection determine where if someone attempted to break into system or not. Network security is the proper safeguarding of all components associated with a network. Security involves the various measures to protect network's components and resource from various threats including physical (e.g., natural disaster, sabotage) and illegitimate users. In generally, security is similar to safety, Security is the condition of being protected against danger and loss [9]. Security issues associated with co-operative routing in multi-hop wireless networks they are as follows [12]: • Confidentiality: The confidentiality property refers to limiting unauthorized access to sensitive information.

1. Traffic control: As the data communication is the most energy-consuming part of the wireless sensor networks by decreasing the amount of traffic, energy can be saved. To distribute traffic effectively from a central node to other nodes, investigations are still needed in the network. 2. Preserve the traffic load balancing:

where $x_i,i=1,2, cdots ,n$ are the states, $underline{x}_i=[x_1,cdots,x_i]^{T} in{R}^i$, $i=1,2, cdots ,n $, $uin {R}$ is the input, and $f_i(cdot)$,$i=1,2, cdots ,n $ are the unknown smooth nonlinear functions which satisfy the global Lipschitz condition. It is assumed that the output $y(cdot)$ is sampled at instants $t_k,k=1,2, cdots ,n$, which represent the sampling instants. $T=t_{k+1}-t_k$ is the sampling interval which is a positive constant. The output signal is available for the observer at instants $t_k+ au_k$, where $ au_k$ are the transmission delays and satisfy $0 leqslant au_k leqslant T$. egin{remark} label{rem:1}

I am very committed to this server and I really want to be able to fix the problems that can drive people away. I really want to be able to address these issues and fix them to the best of my ability. I know I can 't fix every issue, but I do want to try to fix the ones I can. I want to do my part to help make the server a hacker-free, griefer-free place that people of almost all ages can enjoy.

4.0 BLUETOOTH SECURITY STANDARDS 4.1 Wireless Security One of the major problems with wireless technologies is their security. Non-wireless networking technologies require to tap into the actual line to see the flow of bits, however, with wireless all you have to do is be in the range of the transmitting device. This allows anyone with a receiver to pick up the bits “flapping in the breeze”. This causes security to be one of the main areas of concentration for all wireless technologies.

ABSTRACT The key aspect of this research paper is to establish and appraise the current access keycard and password system used in the University of Botswana (UB) against the alternative biometric access control system. Biometrics attributes to the automated recognition of a person based upon their physiological and behavioral characteristics. The experts around the world agree on the concept of biometrics and the types of personalized attributes it revolves around. Using biometrics makes it possible to substantiate a person’s identity based on their physical attributes rather than their possessions (e.g.ID keycard) or what they know (e.g. passwords).

Quiz#2 . With respect to the RPC mechanism, consider the “exactly once” semantic. Does the algorithm for implementing this semantic execute correctly even if the ACK message back to the client is lost due to a network problem? Describe the sequence of messages and discuss whether “exactly once” is still preserved.
