Computer forensics is a sub field in criminal justice discipline which involves employing forensic tactics in order to recover hidden or lost Data Recovery/files on a computer. Sometimes this is conducted in crime investigations to retrieve missing or lost or evidence.
On a recent study published by the forensic journal Richard Swart and Robert Erbacher observe that computer forensics generally involves either the retrieval of data from the a hard disk or an endeavor to evaluate log files as to track down the origin of a security breach.
Computer forensics principal advantage is its power to search and evaluate a pile of Data Recovery efficiently and quickly. They can lookup keywords in a hard disk in various languages which is advantageous since cyber crimes may easily cross past borders via the internet.
Critical data that has been deleted or lost by perpetrators can be recovered which becomes significant evidence in court. Attorneys are able to present this Data Recovery in court which was previously impossible.
One of the key worries of computer forensics is the privacy of the computer owner. In a report released by the US-Cert (United States Emergency Computer Readiness Team) in 2009, the organization observed that legal considerations over privacy concerns are one of the most important problems that have surfaced in the area of computer forensics.
Obviously, those suspected of violent or heinous crimes will, by society’s expectations, surrender their privacy rights momentarily on account of the investigation. It’s still essential, however, to protect one`s privacy in case he/she is have his case dismissed or found not guilty.
Another major drawback of computer forensics is the issue of costs. The costs of maintaining laboratory containing computers, computer analysis tools, and security and software implements to protect Facebook can be tremendous. The US-Cert observes that it is achievable to assemble an affordable work station for the sole purpose of setting up a place to carry out forensic investigations.
Nonetheless, projected costs for most commercially-produced forensic work stations can surpass per unit, as found out by the Walden University School of Computer Forensics Studies. A major issue that has been mentioned by forensic scholars is that forensics investigator may play a part in the upkeep or the destruction of essential data.
Several issues regarding the corruption of key data are important to note. About three possible potential risks exist in the recovery of hidden or lost data. First, there’s the inherent risk that the investigator will for some reason modify the primary data during its acquisition. Secondly, there’s further problems in validating that the retrieved data is even the authentic data from the hard disk where it was retrieved.
