2 Problems related to file security  What is asset register  How to analyze asset  Grading of algorithms  Solution of problem  Conclusion

3  Many of the breaches making headline news are caused by the loss or theft of laptops and other portable devices.  How to encrypt data present in file according to their criticality and sensitivity.  How to decide the criticality and sensitivity of file.  How to select a algorithm which would be most suitable to encrypt data prevailing inside file.

4  To protect themselves from financial and reputational damage, Asset register encryption technologies can reduce risks by ensuring the information on such devices is secure when users are on the move.

5  Anything that has value to the agency that can be communicated or documentary material, regardless of its physical form or characteristics is called an Asset.  Includes, but is not limited to, paper, electronic, digital, images, and voice mail.  Information technology hardware and software are not information assets for classification purposes.

6 Priority is determined on the basis of following parameters :  Confidentiality level (c, 1-10)  Integrity level (i, 1-10)  Availability level (a, 1-10)  Number of user (n) Then, Priority=(c+ (1/n * 10) + i + a)/ (no. of question)
