Encapsulation is the process of “packaging” information prior to transmitting it from one location to another. true or false

1 answer:

3 0

The statement that encapsulation is the process of “packaging” information prior to transmitting it from one location to another is true.

This method augments the data with successive layers of control information before transmission across a network. Each OSI (Open System Interconnection) layer is part of the encapsulation by adding a header to the data packet in the transmission network.

slega [8]

Answer: The statement implies that the hackers psychologically manipulate the human to access the information they need.

Explanation: The author states that the hacker does not only exploits technology to get system access or to gather information. But there is another pivotal part of hacking. He refers to this part as "social engineering".

Social engineering from information security perspective means manipulate human emotions and convincing them to disclose some confidential information. Hacker often hacks or defrauds after gaining confidence and trust of a person.

Phishing is an example. It is a fraudulent technique for getting some secret information. Phisher sends an email pretending to be from some reputable organization to persuade people to divulge private information like passwords and credit card numbers, ATM card pin etc.

The waterfall model and spiral model are variations of SDLC. Do some research to find out what they are and explain how these mo

Radda [10]

Waterfall model and spiral model are used in software development life cycle or SDLC. Any software development process follows one of these models depending on the type of software and the requirements of the customer.

Waterfall model

This model is called as sequential model since it works in stages. The output of first stage becomes the input of the second stage.

The errors of the first stage can be rectified only when it is completed. This is time consuming and makes the process lengthy. Stage 1 is completed before stage 2 begins.

The six stages involved in waterfall model are Requirement Gathering and analysis, System Design, Implementation, Integration and Testing, Deployment of system, and Maintenance.

Spiral model

This model is implemented in iterations. It is also called evolutionary model.

Initially a prototype of the system is prepared. Then, it is followed by development of small parts of the system.

These smaller parts are then assembled to produce the final system.

The four stages which form the spiral model are Identification, Design, Development and Evaluation and Risk Analysis.

The differences between the two models are summarized below.

1. Waterfall model works in linear method. Spiral model follows evolutionary method.

2. Errors and risks are discovered/ rectified after the stage is over. Errors and risks are discovered/ rectified earlier.

3. Waterfall model is suitable for small projects. Spiral model is suitable for large projects.

4. Requirements identification and planning is the initial stage in the waterfall model. Requirements identification and planning is done when needed, in the spiral model.

5. Waterfall model allows little to no flexibility in the system. Spiral model allows flexibility in the system.

6. Low flexibility makes the waterfall model more risky. High flexibility makes the spiral model less risky.

7. Waterfall model, overall, takes less time since requirements are clear. Spiral model is implemented when the requirements of the system are not clear and become clear through prototypes.
