How should an organization think about cyber defense? What are the limits of a ‘perimeter-oriented’ security posture?

mina [271]

Answer:

In the explanation is a short point of view about the cyber defense and the perimeter oriented posture.

Explanation:

To begin with, the concept known as "Cibersecurity" refers to the process of protection of computer systems and everything related to them like softwares, hardwares or any electronic data that could be harmful and sensitive for the company. The reason why this type of practice has been rising up the last years is due to the fact that the "internet of things" has been growing up as well and everyday the companies need to protect their information more and more. Moreover, the "perimeter-oriented" security posture implicates the focus on the external networks as being bad and on the other side the internal networks as being good and stable. So the reason why the companies should consider the cyber defense important is because they need to protect all the information that could be use against them.

Matt inherited as a trust a fifteen-year annuity-immediate with annual payments. He has been told that the annuity payments earn

Pavel [41]

Answer:

effective annual interest rate = 6.32%

annual payment = $1,585

Explanation:

I believe that this is an ordinary annuity, so we can use the future and present value of an ordinary annuity formula:

FV = annual payment x FV annuity factor, so annual payment = FV / FV annuity factor

PV = annual payment x PV annuity factor, so annual payment = PV / PV annuity factor

we can equal both equations:

PV / PV annuity factor = FV / FV annuity factor

FV / PV = FV annuity factor / PV annuity factor

$37,804.39 / $15,077.10 = FV annuity factor / PV annuity factor

2.5074 = FV annuity factor / PV annuity factor

the easiest way to solve this is to use an annuity table since we already know that there are 15 periods (I used an excel spreadsheet):

%,15 periods FV annuity factor PV annuity factor FV/PV

1 16.097 13.865 1.1609

2 17.293 12.849 1.34586

3 18.599 11.938 1.55797

4 20.024 11.118 1.80104

5 21.579 10.380 2.07890

6 23.276 9.7122 2.3966

7 25.129 9.1079 2.7590

8 27.152 8.5595 3.1721

9 29.361 8.0607 3.6425

10 31.772 7.6061 4.4112

The interest rate must be between 6 and 7%:

%,15 periods FV annuity factor PV annuity factor FV/PV

6 23.276 9.7122 2.3966

6.1 23.45404 9.6461 2.43145

6.2 23.63369 9.5858 2.46549

6.3 23.81491 9.52467 2.50034

6.31 23.83312 9.51851 2.50387

6.32 23.85135 9.51236 2.5074

6.4 23.99773 9.46337 2.53585

effective interest rate = 6.32% per year

annual payment = $37,804.39 / 23.85135 = $1,585

1- In 2013, Walmart decided to enter the Indian market in a joint-venture with Bharti Enterprises. Based upon your analysis of W

Ivahew [28]

Answer:

1- Walmart wanted global expansion and it availed the opportunity to expand its business by entering Indian market, however the Indian market is far different than the US market that is why a joint-venture was required to enter the different market as Bharti Enterprises was already operating in Indian market.

2- To enter a new market Joint-venture will be suitable because:

In acquisition the investor acquires all the shares of an existing organisation in this way the investor will not be able to operate with the same name as in other markets as the organisation whose shares are purchased already will have a name which if changed all the goodwill will be lost. In a Joint venture the investor and a local investor invests together to form a different organisation, in this method the organisations jointly own a newly formed organisation in which they both jointly decide the name and the local investor have knowledge about the local market which can be helpful if the customer taste is different than the investors market. In a Greenfield investment the investor purchases shares and bonds of an organisation already operating in the targeted market, in this way the investor will not be able to operate with the same name as in other markets as the organisation whose shares are purchased already will have a name which if changed all the goodwill will be lost.

You own a portfolio that has a total value of $215,000 and it is invested in Stock D with a beta of .86 and Stock E with a beta

babunello [35]

Answer: BP = BD(WD) + BE(WE)

1 = 0.86(1-WE) + 1.39WE

1 = 0.86-0.86WE + 1.39WE

1 = 0.86 + 0.53WE

-0.53WE = -0.14

0.53WE = 0.14

WE = 0.14/0.53

WE = 0.2641509434

WD = 1 - WE

WD = 1 - 0.2641509434

WD = 0.7358490566

The dollar amount of investment in stock D = 0.7358490566 x $215,000

= $158,207.54

Explanation: The beta of the portfolio is 1, which corresponds to the beta of the market. The beta of the portfolio equals beta of each stock multiplied by the percentage of fund invested in each stock(weight). The weight of stock D is equal to 1 - weight of stock E. Therefore, we need to make weight of stock E the subject of the formula by solving the problem mathematically and collecting the like terms. The weight of stock E is 0.2641509434. The weight of stock E will be subtracted from 1 so as to obtain the weight of stock D, which is 0.7358490566. The dollar amount of stock D equal to $215,000 multiplied by 0.7358490566, which is $158,207.54.
