HI thank you for using JA.The major difference between standard and policy are.
#Standard(s) are the recommended status for the community or country. #Policy are rules and should be followed by the community or country.
An example in terms of automobile speed limits.
The policy (or law) might say that drivers must adhere to posted speed limits. This is enforceable and you will be penalized if you are caught disobeying them.
A standard (a clarification of the policy/law) would state that the speed limit is 65 mph on major highways, 25 mph through residential areas, and speed limits are posted on white rectangular signs with black lettering.
A guideline might say that dangerous curves have recommended speed limits posted on yellow diagonal signs with black lettering. These are strong suggestions, but you will not be ticketed if you exceed them.And regarding Practice policy is rules,regulation and procedure that should be followed in within a practice.
These above three are the 3 types of security policies.
A military security policy (also called a governmental security policy) is a security policy developed primarily to provide confidentiality.
The name comes from the military's need to keep information, such as the date that a troop ship will sail, secret. Although integrity and availability are important, organizations using this class of policies can overcome the loss of eitherfor example, by using orders not sent through a computer network. But the compromise of confidentiality would be catastrophic, because an opponent would be able to plan countermeasures (and the organization may not know of the compromise).Confidentiality policy is one of the factors of privacy, an issue recognized in the laws of many government entities (such as the Privacy Act of the United States and similar legislation in Sweden). Aside from constraining what information a government entity can legally obtain from individuals, such acts place constraints on the disclosure and use of that information. Unauthorized disclosure can result in penalties that include jail or fines; also, such disclosure undermines the authority and respect that individuals have for the government and inhibits them from disclosing that type of information to the agencies so compromised.A commercial security policy is a security policy developed primarily to provide integrity. The name comes from the need of commercial firms to prevent tampering with their data, because they could not survive such compromises. For example, if the confidentiality of a bank's computer is compromised, a customer's account balance may be revealed. This would certainly embarrass the bank and possibly cause the customer to take her business elsewhere. But the loss to the bank's "botXXXXX XXXXXne" would be minor. However, if the integrity of the computer holding the accounts were compromised, the balances in the customers' accounts could be altered, with financially ruinous effects.
Network security policy is needed to guide the use of web,email etc.
