During the dawn of 1980s, Personal computers had become quite accessible by the consumers which led to an increase in the criminal activities. A number of new crimes related to computers were detected. This is the reason why Computer Forensic Analysis was introduced by the professionals of Computer Digital Forensics.

The aim of Computer Forensic Analysis is to scrutinize the digital devices. The scrutinisation is sound in terms of forensic manner. The identification, preservation, recovery, analysis, and presentation of the facts regarding the information are the work of the forensic analysis team.

Most of the times it is associated to the scrutinisation of a variety of computer related crimes. But computer forensic analysis can also be utilized in proceedings which are civil in nature.

There was a huge dearth of specialized tools which made the investigators work on live statistics.

Various techniques are used for investigating computer forensic. Some of them include cross drive analysis, live analysis, etc.

Cross drive analysis- it is a technique which relates the information detected on different hard drives. This process is still being worked upon. It is usually used for identifying social network and for performing anomaly detection.

Live Analysis- the scrutinisation of the computers specifically inside their Operating system with the help of customized forensics. It is helpful in handling the encrypting file system.

Deleted Files- it is a very comman technique which is used in forensic analysis of computers. It helps in recovering the deleted files. Most of the times the Operating system does not erase the data. This helps the investigators to recover the file.
