Computer forensics, also known as cyber forensics, involves computer security as well as computer forensic invesigations. This is just one of the latest developments inside fast moving field of forensics, obviously because of the probably faster advancements in computer technology and also the ability of some to manipulate this modern-day tendency with regard to their own gains.
Whereas more traditional forensics involves microscopic investigation of physical properties of any crime, computer forensics requires the minute investigation of computer files and the tracking and movement of those files as well, the hijacking of sites and the sites that people visit. While it can be a misconception that deleted files are not recoverable, a lot more people have become aware of the fact that they can. What this means is that new software keeps emerging that ‘shreds’ those files more finely making it harder for computer forensic experts to piece them back together.
The good news is that as quickly as the developers put out new software, or come up with more advanced techniques to completely remove files, some criminals are just not that savvy or, they don’t have the time to do this properly. Furthermore, some of the best computer forensic experts in the world are on the right side of law and are frequently one step ahead. Whereas normally, the only method to permanently delete files is to overwrite them completely – who knows exactly what the future will bring!
We are not just talking about a desktop or laptop computer here. We are all aware of how mobile phone technology has also advance 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 level of detail can be extremely useful to police officers and the recovery of this data can be vital to furthering a case.
Most people have now heard of ‘hacking’ into computer accounts for various reasons including identity theft. As said, the modern-world relies heavily on storing data, including personal details as well as some really leading-edge government security measures. Not only can someone steal your identity, they can change it with another more unfavorable one! However, one of the most common illegal uses for hackers is to hijack other people’s websites with regard to their own uses, including sending millions of unsolicited spam emails through other people’s accounts. I very much doubt there is anyone who has ever not been a recipient of a minimum of one spam email! Fortunately, computer forensics experts are constantly on the lookout and tracking individuals who do this kind of thing.
If you are a computer forensics expert, the toughest job is usually to be able to convince a court that the material retrieved was really there and just when it was there. This is indeed similar to all branches of forensics and care must be taken at all times to maintain the evidence following proper procedures.
