1a) What are some security concerns with Virtualized Networks?

===================================================================

Virtualization is the type of technology that should be adopted with purpose. Depending on the company, different goals may include anything from reducing capital investments in hardware to increasing the efficiency of existing existing IT systmes.

Network Virtualization can improve security in several ways.

i)Centralizing Confidential Data

ii)Providing Secure Access

iii)Setting Up Sendbox

Virtualization Security Challenges:

======================================

i)Virtualization does a lot to security,but simply using it can introduce all new security risks.

ii)Security threats can evade existing security mechanisms and wreak havoc across the targeted host.

iii)If precautions are not taken DOS attacks to data breaches may compromise vital production aspects within,and possibly outside the virtual environment.

Risks:

========

Specific risks will vary depending on a number of factors

i) Allow Virtual Machines to access the internet

ii) Allow Virtual Machines to access other networked computers and devices.

iii) More Virtual Machines between physical host machines.

1b) Do you feel that a virtualized network is secure enough to host identity information?

==============================================================================================

Yes,Virtualized network is secure enough to host identity information because every host has his personal information.Then we have to protect ourselves.If information is not secure then we will face more problems.This network can keep this in more secure.

Deploying Virtualization in infrastructure provides many benefits,but also it can introduce new risks. Virtualized resources and services should be developed with following security considerations.

i) The host and hypervisor become prime targets. They are often a single point of failure for guests and data.

ii) Virtual Machines can interfere with each other in undesirable ways.

iii) Resources and services can become difficult to track and maintain with rapid deployment of virtualized systems comes an increased need for management of resources,monitoring and maintenance.

iv) Resources such as storage can be spread across and dependent upon several machines.

v) This can lead to overly complex environments and poorly managed and maintained systems.

vi) Virtualization does not remove any of the traditional security risks present in your environment; the entire solution stack, not just the virtualization layer, must be secured.

An article presents a study of the effect of the subbase thickness on the amount of surface deflection caused by aircraft landing on an airport runway. In six applications of a 159 kN load on a runway with a subbase thickness of 407 mm, the average surface deflection was 3.22 mm with a standard deviation of 0.48 mm. a. Can you conclude that the mean surface deflection is greater than 3 mm? Round the test statistic to four decimal places. b. Can you conclude that the mean surface deflection is greater than 2.5 mm? Round the test statistic to four decimal places.You want to test the claim that the average lifespan of a COVID-19 on copper surfaces is greater than 276 minutes. You carefully place samples of COVID-19 on 30 copper surfaces, find the average lifespan, and calculate the test statistic t = 1.28 Find the p-value of the test statistic found. p-value =A statistical program is recommended. An article reported on various chemical properties of natural and artificial soils. Here are observations on x = cation exchange capacity (CEC, in meq/100 g) and y = specific surface area (SSA, in m /g) of 20 natural soils. Minitab gave the following output in response to a request for r. correlation of x and y = 0.854 Normal probability plots of x and y are quite straight.
