Network design requires giveandtake to achieve business goal

Network design requires give-and-take to achieve business goals. What four trade offs would need to be made to achieve maximum security of the network?

Solution

Answer:

Trade offs:

--> A trade-off  is a situation that involves losing one quality or aspect of something in return for gaining another quality or aspect.

--> Tradeoffs can occur for many reasons, including simple physics.

--> The confidentiality of data, so that only authorized users can view sensitive information.

--> The integrity of data, so that only authorized users can change sensitive information.

--> System and data availability, so that users have uninterrupted access to important computing resources.

The Trade offs are

1) Security

2) Usable

3) Cost

--> Information technology is working properly only when users can stop thinking about how or why it works.

--> The fundamental tradeoff between security, usability, and cost is extremely important to recognize.

--> ts possible to have both security and usability, but there is a cost, in terms of money, in terms of time, and in terms of personnel.

-->  Tradeoffs must be made between security goals and goals for affordability, usability, performance, and availability.

--> It will  Also,security adds to the amount of management work because user login IDs, passwords, and audit logs must be maintained.

--> Security features such as packet filters and data encryption consume CPU power and memory on hosts, routers, and servers.

--> Security also affects network performance.

--> Making system or network administrators manage security is counter productive as those job categories then would have conflicting incentives.

--> As a system or network administrator, your job would be to make systems work, make the technology function without users having to think about it, making the technology transparent.

--> There are actually several ways to address this tradeoff. Each vendor\'s technology is used in many different organizations.

--> If we use \"effort” as a proxy for the \"cheap” axis on the tradeoff, we can see that the amount of effort the vendor expends in making their technology usable.

--> As well as secure will offset the amount of effort customers have to expend on the same task.

--> Another tradeoff is that security can reduce network redundancy.

example:

the device becomes a single point of failure. This makes it hard to meet availability goals.

--> Security can also make it harder to offer load balancing.

--> ome security mechanisms require traffic to always take the same path so that security mechanisms can be applied uniformly.

example:

a mechanism that randomizes TCP sequence numbers won\'t work if some TCP segments for a session take a path that bypasses the randomizing function due to load balancing.

--> There are trade-offs between the four dimensions of performance, the fastest service with the highest quality can usually not be offered at the lowest price in comparison to competitors.

--> These trade-offs can be used by businesses to create unique business strategies as well as to distinguish themselves from their competitors.
