Process followed

Evidences for cyber crimes • Cross-drive analysis

A forensic technique that correlates information found on multiple hard drives.

• Live analysis

The examination of computers from within the operating system using custom forensics or existing sysadmin tools to extract

evidence

• Deleted files

A common technique used in computer forensics is the recovery of deleted files. Modern forensic software have their own

tools for recovering or carving out deleted data.

• Steganography

the practice of concealing messages or information within other non-secret text or data.

Cont..• Stochastic forensics

Investigating insider data theft. It is the modern forensic technic came existence.

• PERSISTANT DATA

Meaning data that remains intact when the computer is turned off. E.g. hard drives, disk drives and removable

storage devices (such as USB drives or flash drives).

• VOLATILE DATA

Which is data that would be lost if the computer is turned off. E.g. (deleted files, computer history, the

computer's registry, temporary files and web browsing history).

Forensic tools• Typical forensic analysis includes a manual review of material on the media, reviewing the Windows registry for suspect

information, discovering and cracking passwords, keyword searches for topics related to the crime, and extracting e-mail and

pictures for review.

• Disk Imaging Software.

• Software Write Tools.

• Hashing Tools.

• File recovery programs.

• Analysis Software.

• Password cracking software.

Applications of cyber forensics• FINANCIAL FRAUD DETECTION

• CRIMINAL PROSECUTION

• CIVIL LITIGATION

• “CORPORATE SECURITY POLICY AND ACCEPTABLS USE VIOLATIONS”

Conclusion

• Use of computer in daily life has increased mostly as we humans doesn’t satisfy with limited addition we require more than

are required….,
