What purpose does the MAC serve during the change cipher spec SSL exchange? d. List and define the parameters that define an SSL session state. Solution a)SSH is naturally used to log in to a remote machine and execute commands, however it also holds tunneling, forwarding TCP ports and X11 connections; it can move files utilizing the connected SSH file transfer SFTP or secure copy SCP protocols. SSH exercises the client-server model. c)To integrity defend the first set of messages where the cookies and crypto suite in order is replaced. This will stop a man-in-the-middle attack in step 1 for example, where someone can repress the original message and send a weaker place of crypto suites. d) a. Brute Force Cryptanalytic Attack: An exhaustive look for of the key space for a conventional encryption algorithm. This Attack: The conventional encryption algorithms utilize key lengths sorting from 40 to 168 bits. b. Replay Attack: previous SSL handshake messages are replayed. This is stopped by the employ of nonces. c. Man-in-the-Middle Attack: An attacker interposes during key swap, acting as the user to the server and as server to the user. Man-in-the-Middle Attack: This is stopped by the employ of public-key certificates to validate the correspondents. d.

Information and data security block cipher and the data encryption standard (...
Block ciphers like DES encrypt data in fixed-size blocks and use symmetric encryption keys. DES is a 64-bit block cipher that uses a 56-bit key. It employs a Feistel network structure with 16 rounds to provide diffusion and confusion of the plaintext block. Each round uses subkey-dependent substitution boxes and permutation functions. While DES was widely adopted, cryptanalysis techniques showed it could be broken with less than 256 tries, making the key size too short by modern standards.

Cryptography and network security by Stallings. Question 4.
(a) Is it possible in SSL for the receiver to reorder SSL record blocks that arrive out of order? If so, explain how it can be done. If not, why not?
(b) For SSH packets, what is the advantage, if any, of not including the MAC in the scope of the packet encrytion?
Solution
a) SSL relies on an underlying reliable protocol TCP to assure that bytes are not lost or inserted. There was some discussion of reengineering the future TLS protocol to work over datagram protocols such as UDP, in which case out-of-order blocks cannot be handled. So it depends on the transport layer protocol SSL/TLS runs on.
b)
As alluded to by Palo Ebermann\'s comment, the word authentication has a different meaning in the two scenarios you mentioned.
In the key exchange phase of SSH, the purpose of authentication is to ensure to both parties that they are indeed talking to the right peer (if using mutual authentication). Typically, the server authenticates itself using its public key and the client uses a username and password.
In the SSH record layer phase (i.e., the sending of the actual application data), the purpose of authentication is to protect each individual data packet from tampering. This is achieved using the MAC. To encrypt application data SSH typically uses either AES in counter mode or in CBC mode. Neither of these modes of operation provides protection against tampering of the ciphertext. Thus they need to be accompanied with a MAC in order to detect this.
Consider e.g., the silly example where Alice sends the following message encrypted using AES in counter mode, but without any MAC: Transfer 100 USD from Alice to Bob. Then someone (Bob?) could flip a few strategically placed bits in the ciphertext, so that it would actually decrypt to Transfer 10 000 USD from Alice to Bob. instead. Note that without any MAC, it would be impossible for the recipient to notice that this ciphertext had been tampered with. Also, observe that this fact is completely independent of any key exchange that has been done prior to the tampering.

TLS is a cryptographic protocol that provides communication security over the internet. It allows for confidentiality and authentication of communications through key exchange and encryption of the record layer. However, TLS has faced numerous attacks over the years that exploit weaknesses in its implementations, cipher suites, and compatibility with older versions. Ideal patches often require removing vulnerable features completely, but real-world patches typically aim to preserve compatibility and usability while improving security. As a result, attacks on TLS continue to emerge as new vulnerabilities are discovered.
Study and Analysis of some Known attacks on Transport Layer Security
This paper is focused on study on some practically feasible attacks and threats against TLS based connection. The reader can also get an idea on SSL Strip attack presented here based on an experiment in a testbed environment. There are also some other attacks on TLS protocol such as BEAST, Padding Oracle Attack, STARTTLS command injection attack, Theft of RSA Private Keys, Triple Handshake etc. which are also discussed here descriptively. This study summarizes the common known attacks following RFC 7457 and their existence, appliance and remedies for the TLS activated server.

For public-key cryptography, it describes the principles including key distribution and encryption/decryption with public/private key pairs. Specific public-key algorithms covered are RSA, Diffie-Hellman key exchange, and their applications for encryption, digital signatures, and key exchange. Requirements and examples of the RSA algorithm are also summarized.
Unit 3
1. Digital signatures provide authentication of digital documents by using asymmetric cryptography techniques. A digital signature is generated using a private key and can be verified by anyone using the corresponding public key.
2. There are various types of attacks against digital signature schemes like key-only attacks, generic chosen message attacks, and adaptive chosen message attacks. The security goals are to prevent total key breaks or the ability to forge signatures selectively or existentially.
3. A secure digital signature scheme must produce signatures that depend on the message, use secret information to prevent forgery and denial, be efficient to generate and verify, and make forgery computationally infeasible. Timestamps can be included to require message freshness.
DCS Unit-II COMMUNICATION AND COORDINATION.pdf
The document discusses various aspects of interprocess communication (IPC). It describes IPC as communication between processes in a distributed system. There are two main types of IPC - synchronous which blocks send/receive operations, and asynchronous which uses non-blocking sends. IPC can use protocols like TCP and UDP, with UDP providing message passing between processes. Request-reply and multicast communication patterns are also covered. Multicast allows sending a message to multiple processes simultaneously. The document also discusses concepts like sockets, marshalling, and different IPC architectures and algorithms.

Hiding message from hacker using novel network techniques
we address the trouble of selective jamming attacks in wireless networks. In these assaults, the adversary is energetic best for a brief period of time, selectively concentrated on messages of excessive significance. We illustrate the benefits of selective jamming in phrases of network performance degradation and adversary effort with the aid of offering case research. A selective assault on TCP and one on routing. We show that selective jamming attacks can be launched with the aid of performing actual-time packet classification at the physical layer. To mitigate these attacks, we develop 3 schemes that prevent actual-time packet class via combining cryptographic primitives with physical-layer attributes. We analyze the security of our strategies and examine their computational and communication overhead.

Transport layer security
Transport Layer Security (TLS) is a standard security protocol that ensures secure connections on the Internet. It is based on the earlier SSL protocol with minor differences in record format version numbers, use of HMAC for message authentication codes, and additional alert codes. The goals of TLS are to establish a secure connection through cryptographic security, allow for interoperability between independent implementations, and provide an extensible framework to incorporate new encryption methods. TLS uses the record layer to encapsulate and process messages through steps like fragmentation, encryption, integrity checks. It generates cryptographic secrets through pseudorandom functions and data expansion functions.
All programming assignments should include the name, or names, of th.pdf
All programming assignments should include the name, or names, of the
students. This information should be placed in the introductory comments
section. The introductory comments should also contain the purpose of the
program. Clear, concise, commenting is an important skill to develop and
will be part of the grade for each program. Programs should be submitted
via Blackboard as “.cpp” source programs. Each member of a team should
submit a copy of the program.
The purpose of PSA 7 is practice our programming style and techniques on
a fairly simple real world example of an application. PSA7.cpp is a program
that analyzes various aspects of the clients at an animal shelter. Your task
is to fill in the three routines that provide the necessary information to the
main routine. You may not alter the code in main. You must use the
interfaces as defined.
The first two routines are almost trivial and the only thing that is special
about one of them is the need to use a persistent variable.
The third one, shotRecord is a bit challenging. You must determine if each
animal has had the correct shots. These are for Parvovirus, Rabies, and
Bordetella. One confusion factor here is that they could have also received
a shot for Leptospirosis; that is not a required shot. Further complicating
things is the fact that the only thing that is important is that they received
the shot; they may have received their inoculations in differing orders.
Programme it using \"CODE::BLOCK and also use the main function below:
#include
#include
#include
#include
using namespace std;
#define numberSpecies 4
#define numberShots 3
enum species {dog, cat, bird, rabbit};
enum shots {Parvovirus, Rabies, Bordetella, Leptospirosis};

}
bool shotRecord(struct animal *animal)

temp = 0;

// This is the trickiest one!
return (temp == 3) ? true: false;

A selective assault on TCP and one on routing. We show that selective jamming attacks can be launched with the aid of performing actual-time packet classification at the physical layer. To mitigate these attacks, we develop 3 schemes that prevent actual-time packet class via combining cryptographic primitives with physical-layer attributes. We analyze the security of our strategies and examine their computational and communication overhead.

Transport layer security
Transport Layer Security (TLS) is a standard security protocol that ensures secure connections on the Internet. It is based on the earlier SSL protocol with minor differences in record format version numbers, use of HMAC for message authentication codes, and additional alert codes. The goals of TLS are to establish a secure connection through cryptographic security, allow for interoperability between independent implementations, and provide an extensible framework to incorporate new encryption methods. TLS uses the record layer to encapsulate and process messages through steps like fragmentation, encryption, integrity checks. It generates cryptographic secrets through pseudorandom functions and data expansion functions.

All programming assignments should include the name, or names, of th.pdf
All programming assignments should include the name, or names, of the
students. This information should be placed in the introductory comments
section. The introductory comments should also contain the purpose of the
program. Clear, concise, commenting is an important skill to develop and
will be part of the grade for each program. Programs should be submitted
via Blackboard as “.cpp” source programs. Each member of a team should
submit a copy of the program.
The purpose of PSA 7 is practice our programming style and techniques on
a fairly simple real world example of an application. PSA7.cpp is a program
that analyzes various aspects of the clients at an animal shelter. Your task
is to fill in the three routines that provide the necessary information to the
main routine. You may not alter the code in main. You must use the
interfaces as defined.
The first two routines are almost trivial and the only thing that is special
about one of them is the need to use a persistent variable.
The third one, shotRecord is a bit challenging. You must determine if each
animal has had the correct shots. These are for Parvovirus, Rabies, and
Bordetella. One confusion factor here is that they could have also received
a shot for Leptospirosis; that is not a required shot. Further complicating
things is the fact that the only thing that is important is that they received
the shot; they may have received their inoculations in differing orders.
Programme it using \"CODE::BLOCK and also use the main function below:
#include

Why steroids can cross the cell membraneWhy steroids can cross .pdf
Why steroids can cross the cell membrane?
Why steroids can cross the cell membrane?
Solution
Steroids are organic molecules, found in our body in the form of cholesterol, steroid hormones,
vitamin D and also in the form of medicinal drugs. The steroids are non-polar and are similar to
lipids. These molecules play a very important role in cell membrane stability and also in signal
transduction in the body.
To carry out the different functions in the body, the steroid molecules must enter the cell and
bind to its target receptor and initiate the cascade of cellular response. The cell membrane is
made of phospholipids with polar head groups of lipids on the exterior of cell surface and
towards the cytosol, and the non-polar chains in the middle.
This architecture of the cell membrane allows steroids to cross the cell membrane being
lipophilic. The entry of steroids in the cell might take place with the help of receptors or carrier
proteins..

Why is “Profit” a problematic target Please consider in your answer.pdf
Why is “Profit” a problematic target? Please consider in your answer different types of profit, the
possible differences between profit and turnover (=sales) as a measure and also the definitions
and meaning of profit/capital ratio(s).
Solution
\"Profit\" is a problematic target because it includes wide range of emotions and and issues
among respondents i.e. they ranged acceptable profit to profit effect on decision making and
future variability of capitalization. in same way today\'s cash is driven by yesterday;s decision
making on pricing. Profit is the difference between income a business generates and expenses
incurred in business running.
Types of Profit -
1. Gross Profit - Gross profit is difference between all sales of the company and cost of
producing the products for a company. this mainly used by company officials when making
decision about pricing and what material to be used in manufacturing part of business.
2. Net Profit - Net profit subtracts all of the expenses of company from its gross sales. The net
profit is and indicator that how business performing over the time.
3. Net Profit after Interest and Tax - Net profit of a company further reduced when interest and
taxes are deducted from profit.
4. Retained Profit - Retained profit is any profit remaining after the shareholders receive their
dividends.most of the time this funds will reinvested in company.
Differences between profit and turnover -
Turnover is net sales generated by firm while profit is earning of a firm after all expenses have
been charged against net sales.Thus Turnover and Profit is beginning and ending points of the
income statements.
A difference between turnover and profit is that a rising in turnover may be a sign that business
is growing but profit is and indicator of health of business.
The definitions and meaning of profit/capital ratio - Profit capital ratio expressed as percentage,
complements ratio by add a company\'s debt liabilities, or funded debt, to equity to reflect
company\'s total capital. This ratio measures narrow focus to gain a better understanding of
company\'s ability to generate returns from available sources..

Which cable type would be used to connect a router to a switch?
A. Straight-through
B. Crossover
C. Rollover
D. None of the above
Solution
A is correct. Switches and routers have different pinouts; therefore, a straight-through cable
should be used.
B, C, and D are incorrect. B is incorrect because a crossover cable will not work between two
devices of different pinouts. C is incorrect because rollover cables are used between a PC and a
router/switch console port. D is incorrect..
What is the role of abiotic factors in the formation of biomesS.pdf
What is the role of abiotic factors in the formation of biomes?
Solution
A biome is a large terrestrial region characterized by a specific type of climate and dominant
plant life. There are a variety of terrestrial biomes contributing to the biodiversity on the earth.
The living components of a biome include the organisms with life such as plants, animals,
microbes and all living organisms. The non living components or abiotic factors include the
components without life such as water, air, nutrients, heat and solar energy.
For example, biomes like tropical rain forests are found at the equator with hot, moisture air rises
dumping the moisture in the land. These forests have warm temperatures, high humidity and
heavy rain fall daily. The forests are dominated by broad leaf ever green plants and much of
animal life specifically large insects, bats and birds are abundant. Tree climbing animals and
decomposers are heavily populated in tropical rain forests. These forests show great biodiversity
with suitable climatic conditions for survival of all type of animals.
The abiotic factors such as warm temperatures, moist air and rainfall daily keep the vegetation of
the forest growing to provide nutrition for all kinds of organisms live in the biome. The sunlight
helps the plants to synthesize nutrients and to provide them to plant dependent organisms. Thus,
abiotic factors like temperature, sunlight, air and nutrients influence the growth, reproduction
and survival of organisms in the ecological food chain in a biome..

What are the major terrestrial adaptations of plants1- List the F.pdf
What are the major terrestrial adaptations of plants?
1- List the FOUR major challenges plants encountered as they evolved on to land.
2- Next to each challenge, provide at least ONE (or more) example(s) of an adaptation that meets
that challenge. Refer to Ch 17, Section 17.1 (pp 342-43)
Follow format below:
Challenge 1- Adaptation(s)
Challenge 2- Adaptation(s)
Challenge 3- Adaptation(s)
Challenge 4- Adaptation(s)
Solution
the four major challenges observed in all terrestrial plants include the following.
there is an alternation of generations,
a sporangium formation is seen,
a gametangium giving rise to haploid cells,
Apical meristem tissue which develops from roots and shoots.
challenge 1- Alternation of generations: Ferns reproduce using alteration of generations. it is a
diploid sporophyte and by meiosis produces single-celled haploid spores which are dispersed by
air, wind or floating water. after the spore reaches appropriate conditions, it will germinate and
form prothallus which carries out sexual reproduction forming a sporophyte.
challenge 2- Sporangia in the Seedless Plants: sporophytes of seedless plants are diploid and are
a result of syngamy or fusion of 2 gametes. sporophyte contains sporangia which are a
reproductive sac containing spores. inside the sporangia, diploid sporocytes or mother cells
produce haploids by meiosis thereby reducing chromosome number from 2n to n. These spores
get dispersed in the environment. ferns, mosses are one such
challenge 3- Gametangia in the Seedless Plants: seedless plants produce sperm with flagella and
swim into a moist environment to the archegonia which are the female gametangium. later, the
embryo develops inside as sporophyte. Liverwort plants are one example for such adaptation.
challenge 4- Apical Meristems: by rapid cell division in the tissues, the length of roots and
shoots increases which give rise to apical meristem. it is a small zone of cells present at the shoot
tip or root tip. Elongation of these shoots and roots helps the plants to access additional use
natural resources such as light by shoots and water by roots. Apple seedlings are examples where
apical meristems give rise to new shoots and root growth.
The total lung capacity of a patient is 5.5 liters. Find the patient.pdf
The total lung capacity of a patient is 5.5 liters. Find the patient’s inspiratory reserve volume if
the patient’s vital capacity was 4.2 liters, the tidal volume was 500 ml, and the expiratory reserve
volume was 1.2 liters.
Solution
Answer:
Inspiratory reseve volume (IRV )= VC - (TV + ERV)
VC= Vital capacity
TV= Tidal volume
ERV= Expiratory reseve volume
= 4.2- (0.5 + 1.2)
= 2.5 Liters.

This making is called internet generation since internet has got lots of control over our existence.
All we do, internet has got more to do with it. We converse study, work and learn during internet
so internet has been an essential part of our life. Growth of telecommunications was occurring
far before the development of internet; however internet has assisted in bringing the one form of
telecommunications into more than a few forms. The enlargement of telecommunications and its
fame has lot to do by internet. Internet completes the telecommunication procedure much easier
and earlier. As it attaches a system with another system, Network is in addition a form of
internet, we name it intranets. Internet was developed in 90s and that is the period since when
information technology has been getting expanded in a faster speed.
Internet has been the catalyst for the act and development as well as exactness, growth and fame
of telecommunications, networking and information technologies consequently I think its
praiseworthy to say that as of internet, development of telecommunications, networks and other
information technologies get the speed..
Technology is an ever-growing system that provides advantages and in.pdf
Technology is an ever-growing system that provides advantages and introduces disadvantages
into organizations. Identify an organization that has introduced new or improved technologies to
enhance its information systems. Discuss the technologies that were selected to enhance the
company\'s competitive advantage. Explore some advantages and related disadvantages
introduced through this technology integration.
Answer needs to be 200 - 300 words.
Solution
Health care organizations have had to adapt to many changes in the world around them, from
advances in diagnostic and therapeutic procedures to the emergence of administrative
innovations such as managed care and the invention of new information technologies. The
Internet represents a particularly profound change that will enable or force significant changes in
organizational form and processes—a transformation as profound as any that have gone before.
The Internet\'s capability to empower consumers, support dynamic information exchanges
among organizations, and \"flatten\" organizational hierarchies promises to result in new
operational strategies, business models, service delivery modes, and management mechanisms.
The changes will have such far-reaching implications that health care organizations need to start
preparing now to adopt the advanced Internet applications that are expected to appear in the near
future. Organizations need to evaluate the potential and implications of new Internet
technologies, adapt them to local needs and conditions, minimize the risks associated with new
product and service deployment, and plan to demonstrate the value of their efforts.
This chapter examines challenges to the adoption of Internet-based technologies by health care
organizations. It attempts to identity fundamental impediments to greater use of the Internet that
may be expected to persist for some time. The first section of the chapter provides a context for
the analysis by reviewing the experiences of other industries that have achieved some success in
changing business practices by adopting Internet technologies. The second section discusses in
general terms why more health care organizations should be interested in adopting the Internet:
because it can advance their strategic interests. The third section deals with organizational
barriers that hinder Internet use. The discussion there addresses internal and external factors,
such as policy and technical barriers, that influence and constrain the form and extent of Internet
use, as well as the range of uncertainties that inhibit decision making regarding the Internet. The
last section addresses the importance of organizational leadership..

Select all of the following that are true regarding evolution. Altho.pdf
Select all of the following that are true regarding evolution. Although not all transitional
organsisms have been preserved, scientists have unearthed many, including the tiktaalik.
Evolution is a theory about how life originated Complex human structures did not evolves as a
single functioning unit, but slowly over millions of years, piece by piece. Evolution is a theory
or a well-established and accepted scientific model that is based on extensive experimentation
and observation. Mutations that cause variation originate spontaneously by chance, but natural
selections drives evolution and is not random. Evolution is both observable and testable;
populations have been observed evolving in the laboratory and in the field. Evolution is a theory
about how the diversity of life emerged after life originated. Human traits are too complex to
have originated by random chance. Evolution is not observable or testable. Evolution is just a
theory and therefore does not have much evidence to support it. There are no transitional fossils.
Solution
Following are the true statements regarding Evolution.
Role of involvement in consumer decision-making. Identify the level .pdf
Role of involvement in consumer decision-making. Identify the level of involvement a customer
might use to make a purchase/no purchase decision of a cell phone. Then, discuss which type of
buying behavior is most consistent with that level of involvement.
Solution
Consumer involvement refers to degree of information processing or extent of importance that a
consumer attaches to a product.The degree of involvement has a very significant effect on
consumer behaviour. When more expensive products are to be purchased, the consumer gets
more involved in purchase process but he may not be equally involved in a product which is just
a rupee or two priced.
When consumers decide to buy a product based on the interest and importance of the product to
them, this is defined as involvement level. In other words, it measures how personally, socially
and economically involved the customer is with the product in order to buy it.
Levels of Involvment:
LOW INVOLVEMENT- Low involvement purchases are not really important to consumers,
have little relevance and need very limited information processing.(Example:Tea,
toothbrush,Washing powder.)
SOME INVOLVEMENT- Some involvement purchases are of little bit importance to customers.
It includes some evaluation of alternatives.(Ex: Skin cream,Torch, snacks)
HIGH INVOLVEMENT- High involvement purchases are those which are important to
consumers such as complex, expensive, risky or ego-intensive products & require extensive
information processing.(Ex: Cars, diamond, cell phone)
Therefore, it is evidend from the above analysis that the decision to purchase a cell phone
requires high involvement.
Extensive decision making is most consistent with that level of involvement.
Questionsa What are some of the barriers to understanding an issu.pdf
Questions
a: What are some of the barriers to understanding an issue as complex as Climate Change?
b: Are you surprised by how people have ‘used’ the information about a hiatus?
c: Are arguments establishing global warming sufficient to promote action on climate change or
not?
d: Assuming you were to believe in anthropocentric climate change, using the arguments in this
subject, are you in favour of taxes or cap and trade for addressing climate change? Why or why
not? PLANETOZ BYGRAHAMREADFEARN Global warming has not stopped. People should
understand that the planet is a closed system. As we increase our emissions of greenhouse gases,
the fundamental thermal dynamics tells us we have added heat into the system. Once it\'s
trapped, it can go to a myriad of places-land surface, oceans, ice shelves, ice sheets, glaciers for
example HOSTED BY THE GUARDIAN England explained how the winds help the ocean to
absorb heat into the thermocline-that\'s roughly the area between 100 metres and 300 metres
deep. He says once the trade winds drop which is likely to come within years rather than decades
- then the averaged surface temperatures will rise sharply again. The \'pause\' in global warming
is not even a thing Media outlets across the world have extensively covered England\'s paper.
National Geographic told us the study revealed how the heat had been \"hiding\" in the oceans.
All signs point to an acceleration of human-caused climate change. So why all this talk of a
pause? Over at the ABC, we were told the paper gave an explanation for \"a pause in global
warming\" and that \"over the past 15 years the rate of global warming has slowed - and more
recently almost stalled.\" The IPCC in 2013 pointed out that more than 90% of the world?s extra
heat is being soaked up by the oceans, rather than lingering on the surface. Photograph:
Universal History Archive\'Getty Images On The Conversation, we had \"Global warming stalled
by strong winds driving heat into oceans The idea that global warming has \"paused\" or is
currently chillaxing in a comfy chair with the words \"hiatus\" written on it has been getting a
good run in the media of late. Even though these reports spoke in detail about the complexity of
the research (England feels the coverage generally has been very good), they could inadvertently
cement the idea that global warming has in some way stopped, when it hasn\'t. Much of this is
down to a new study analysing why one single measure of climate change- the temperatures on
the surface averaged out across the entire globe - might not have been rising quite so quickly as
some thought they might. But this is almost unavoidable. You can hardly blame journalists and
commentators for repeating the phrase that \"global warming is in a hiatus\" when the offending
word is in the itle of the scientific paper itself (Recent intensification of wind-driven circulation
in the Pacific and the ongoing warming hiatus But here\'s the thing. There never was a \"paus.

Village of Aurora was never flooded before the Year 2016. Ever since a new development in the
neighboring city, the area started to experience the flood in 2017. An investigation was launched
and found that the new development was the cause of the flood for the downstream area
including the Aurora Village. What measures can be applied to mitigate the flood for the
downstream area?
Solution
The major development project which causes the flooding of the down stream areas are dams,
dams have both advantages and disadvantages in their own way, compared to the disadvantages
the advantages are more when compared in the long run, one of the major problem is flooding of
villages in the down stream areas and a lot of ecosystem is submerged while construction of the
dam, the following measures can be taken to prevent the flooding of areas in the down stream:
1. Design the dam in such a way that there would be minimum impact on the environment and
the population living nearby
2. If the soil is not fertile, then stabilize the soil if not done the erosion takes place
3. Remeandering of rivers is to be done so that they are in their natural course itself
4. Provide more reservouir for storing of water
5. Provide an alarming system for reducing of impact on the surrounding population
6. Provide sufficient number of crest gates to control the flow in case of floods
7. Construct the buildings above the ground level in flood prone areas, so that the houses will not
be damaged
The above measures would be sufficient enough to diminish the effect of flood in a given area..
Quality software project managementHow are tasks, activities, and .pdf
Quality software project management
How are tasks, activities, and phases most typically related to each other with respect to a
project? chapter 1
Solution
Answer :-
Software Project Management :
Tasks :
The during the development phase, everything that will be needed to implement the project is
arranged. Potential suppliers or subcontractors are brought in, a schedule is made, materials and
tools are ordered, instructions are given to the personnel and so forth. The development phase is
complete when implementation is ready to start. All matters must be clear for the parties that will
carry out the implementation
Activitie :
An activity is a major unit of work to be completed in achieving the objectives of a process. An
activity has precise starting and ending dates, incorporates a set of tasks to be completed,
consumes resources, and results in work products. An activity may have a precedence
relationship with other activities. For example, finish-to-start, start-to-start, finish-to-finish .
Phases :
The 5 Phases of a Project :
1) Project Initiation Phase :
A project is formally started, named and defined at a broad level during this phase. Project
sponsors and other important stakeholders due diligently decide whether or not to commit to a
project. Depending on the nature of the project, feasibility studies are conducted. Or, as it may
require, in an IT project – requirement gathering and analysis are performed in this phase. In the
construction industry a project charter is completed in this phase.
2) Project Planning Phase :

duration, quality, communication, risk and resources. Some of the important activities that mark
this phase are -making WBS, development of schedule, milestone charts, GANTT charts,
estimating and reserving resources, planning dates and modes of communication with

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

- 1. 1a. Describe the SSH protocols. For what applications is SSH useful? b. Are there any advantages in not including the MAC in the scope of the packet encryption in SSH? c. What purpose does the MAC serve during the change cipher spec SSL exchange? d. List and define the parameters that define an SSL session state. Solution a)SSH is naturally used to log in to a remote machine and execute commands, however it also holds tunneling, forwarding TCP ports and X11 connections; it can move files utilizing the connected SSH file transfer SFTP or secure copy SCP protocols. SSH exercises the client-server model. c)To integrity defend the first set of messages where the cookies and crypto suite in order is replaced. This will stop a man-in-the-middle attack in step 1 for example, where someone can repress the original message and send a weaker place of crypto suites. d) a. Brute Force Cryptanalytic Attack: An exhaustive look for of the key space for a conventional encryption algorithm. This Attack: The conventional encryption algorithms utilize key lengths sorting from 40 to 168 bits. b. Replay Attack: previous SSL handshake messages are replayed. This is stopped by the employ of nonces. c. Man-in-the-Middle Attack: An attacker interposes during key swap, acting as the user to the server and as server to the user. Man-in-the-Middle Attack: This is stopped by the employ of public-key certificates to validate the correspondents. d. Password Sniffing: Passwords in HTTP or additional utilization traffic are eavesdropped.this User data is encrypted.
