The end result every person wants is to keep their data safe. Thus, to achieve this there are some ground rules to follow. There are some principles to follow.

The principles for information security are:

1. Integrity:

Maintaining the consistency and the accuracy of data through its whole life cycle. This process ensures that the data is not modified in an unauthorized manner or undetected manner.

2. Availability:

An information is only useful for a person if that is available at the time of his need or its availability is good. This could only be established is the computer systems storing the information, the information security protocols, and the channel through which it would travel are functioning properly.

3. Authenticity:

When we think of e-business it is of paramount importance that data provided by the user is correct and genuine. One more important thing to validate is the identity of both parties involved. That is they are exactly who they actually claim to be or some imposter on the net. To ensure thus some information security systems have provisions like digital signatures and other ways to ensure and provide authentication.

4. Non-repudiation:

In the book of law, non-repudiation means that both parties in a contract cannot deny their involvement in it. It could be also thought as that two parties involved in a transaction cannot deny their participation. i.e. the person receiving cannot deny his receiving that sum of money and the person sending cannot refuse his sending that sum.
