Why cyber crime thrives 

Cybercrime will probably keep growing because it is non-violent and very lucrative yielding high profits.

It is also difficult to capture cybercrime, and when convicted, cybercrimes attract short jail terms. Judges tend to have a biased view of cyber criminals that portrays .

the criminals as intelligent but misguided individuals as opposed to the thugs they really are. The general laws do not adequately address cybercrime.

Such laws are not up to date with the developing and evolving computer technology. 

The role of computer forensics 

Computer forensics serves to uncover computer related crime such as hacking, internet frauds, and child pornography. Digital investigations also help resolve other offences such as terrorism, murder, drug smuggling,

extortion, tax evasion, organized crime as well as robbery cases. Terrorists use the internet to recruit members while social media platforms create an avenue for sexual predators to target and stalk potential victims. 

Computers hold a vast amount of data that include images, email messeges, email addreses, internet history, research, phone numbers, documents, videos, research an contact list.

Such data remains in the computer storage even after deletion allowing interrogators to track criminal activities. Deleting files just hides them from the user facilitating their recovery when the need arises. 

Almost everything a user does on a computer system will leave some traces. Backup files, internet history cache, registry entries and even deleted files can be used to determine computer activities.

Investigators use server logs to obtain information about computers that access a website. Cyber investigations gather, examine and report data found on devices and networks that are important in a court proceeding. 

The tools used in cyber crime investigation help in data recovery. Such include tools for data capture, file viewing, registry analysis, file analysis, internet analysis and many others. The tool of choice depends on the cost and availability of experts. 

Computer crime experts use GPS software embedded in phones, vehicles, and statellite navigation systems to monitore the whereabouts of a suspect. GPS settings such a preferred language, contact list among others can help identify a criminal. 

Computer Forensics employs various tools to acquire and provide digital as well as physical evidence in a criminal or administrative case. Law practitioners rely on the testimony of computer forensic experts to aid in retrieval and preservation of proof pertaining cybercrime. Therefore they help identify offenders and analyze evidence against them.
