Question
When designing a firewall system and its corresponding security policy, a number of questions should be answered. The first question involves the company’s expected level of security. Is the company trying to restrict all access to services not deemed essential to the business? Or does the company wish to allow all or most types of transactions, thus asking the firewall system only to audit transactions and create an orderly request for transactions? A second question stems from the first decision: How much money is the company willing to invest in a firewall system? A third question relates to the company’s commitment to security. If the company is serious about restricting access to the corporate network through a link such as the Internet, will the company be equally serious about supporting security on any and all other links into the corporate network environment?Explanation / Answer

A second question stems from the first decision: How much money is the company willing to invest in a firewall system?
A third question relates to the company’s commitment to security. If the company is serious about restricting access to the corporate network through a link such as the Internet, will the company be equally serious about supporting security on any and all other links into the corporate network environment?
ANSWER 1:
The answer to the first question depends on what type of company it is. If the company works on very critical and confidential things then it may block access to services other than the required ones to prevent anyone misusing the services other than the company specified one.
But for companies who usually works on various domains and the company cannot determine which services to block and which should not be the 2nd approach can be taken. This will block some general services but most of the services will be open for use, but the firewall will audit the access to ensure that no one can misuse the service.
ANSWER 2:
Firewalls are the essential part of the company network. Whether it is a small or a large company.
Most of the company will spent a significant amount to setup a good firewall, but some may goto a larger expense to protect any very critical and confidential data’s present in their network. And some companies will stick to a standard expense as most of the security is already provided from the standard firewall installation and the company does not have any especial business domain for which special expenses has to be done for strengthening the firewall more.
ANSWER 3:
Yes, usually most of the company, commits that it will give security to all other links into the corporate company will spent a lot of amount and effort to make sure every links are monitored and restricted.
The company network is the companies’ backbone and they will do anything to secure it.
The company can incorporate various firewall measures to make sure that every channel is secured and monitored.
Only the small companies that cannot afford this kind of security will not incorporate this but at least they will have a monitoring system to monitor all the incoming and outgoing network traffic
