Computer forensics includes computer security and computer forensic investigations and is sometimes termed as cyber forensics. This is just one of the latest developments inside fast moving field of forensics. Probably as a result of faster advancements in computer technology and the ability of some individuals who wish to control this medium for their own gains.
Whereas more common forensics involves microscopic investigation of physical properties of any crime, computer forensics involves the minute investigation of computer files and the tracking and movement of those files as well, the hijacking of sites and the sites that individuals visit. While it might be a misconception that deleted files are unrecoverable, more and more people are now conscious of the fact that they certainly are. This implies that new software keeps emerging that ‘shreds’ those files more finely which makes it more difficult for computer forensic experts to meld them back together.
The great news is that as fast as the developers put out new software, or develop more complex methods to completely eradicate files, some criminals are just not that savvy or lack the time to do this properly. Also, some of the better computer forensic experts in the world sit on the right side of law and are usually one step ahead of their counterparts. Whereas normally, the only way to permanently delete files is to overwrite them completely - who knows exactly what the future will provide!
We are not just discussing a desktop or laptop computer here. We are all aware of how cell phone technology has also advanced with the likes of the iphone and similar devices, some are now used to store data files as well as names and contact numbers of the user. This information can be very useful to law enforcement officials and the recovery of this data can be vital to advancing a criminal case.
Most people have now heard of ‘hacking’ into computer accounts for various reasons including identity theft. As previously said, the modern-world relies heavily on storing data, including many personal details as well as leading-edge government security measures. Not only can someone steal your identity, they can change it with another more undesirable one for their own benefit! However, one of the most common illegal uses for hackers is to hijack other people’s websites for their own uses, including sending numerous unsolicited spam emails through other people’s accounts. I very much doubt there is anyone who has never been a recipient of at least one spam email! Thankfully, computer forensics experts are constantly on this problem and track those that do this sort of thing.
If you're a computer forensics expert, the most challenging job is usually to convince a court that the material retrieved was really there in the first place and just when it was there. This is indeed similar to all branches of forensics and care must be taken of the evidence by following proper procedures.
