The first step in devising security services and mechanisms is to develop a security policy.
A security policy is a document that states in writing how a company plans to protect the company's physical and information technology (IT) assets. A security policy is often considered to be a "living document", meaning that the document is never finished, but is continuously updated as technology and employee requirements change. A company's security policy may include an acceptable use policy, a description of how the company plans to educate its employees about protecting the company's assets, an explanation of how security measurements will be carried out and enforced, and a procedure for evaluating the effectiveness of the security policy to ensure that necessary corrections will be made.
This is the required answer.
Answer: Server are optimized so that they can work efficiently and improve their performance while working. Application server optimization mechanism can be used for optimizing the server with respect to the application.
Some of the techniques used in the application server optimization are as follows:-
- Load balancing- which helps in upgrading throughput ,improves the time of response, enhance the bandwidth of network etc.
- Fail-over management- it is used for decrement of latency, balancing the server, increasing the availability of network and it resources etc.
