Device Forensic Data Wipe is a safe and secure way of completely erasing user data from a device, this process will give you peace of mind that any precious or confidential data will not be misplaced and the device can be repurposed or recycled effectively afterwards.
Data wiping is the process of logically removing data from a read/write medium so that it can no longer be read.
Forensic software is used to collect raw data from digital storage devices, including the recovery of hidden and deleted files, in support of e-discovery and investigations of digital activity.
Destroying Evidence by Formatting, Sanitizing or Wiping. Attempting to securely wipe or otherwise destroy evidence stored on hard drives and other media can be the planned last resort. If done properly, secure erase will irreversibly destroy evidence without giving investigators the slightest chance of recovery.
Data erasure (sometimes referred to as data clearing, data wiping, or data destruction) is a software-based method of data sanitization that aims to completely destroy all electronic data residing on a hard disk drive or other digital media by overwriting data onto all sectors of the device in an irreversible process.
If the data is on a company owned computer it's their data - not yours. If you delete data you don't own without authority then that's illegal in most jurisdictions.
Wiping a computer hard drive is different from shredding because it merely erases any stored information while keeping the physical hard drive intact. This is also different from moving documents to the trash or recycle bin because, even though the files are hidden from view, they remain on the device.
Wipe Means Write
Wiping the hard disk means actually erasing the data in the disk sectors. For maximum security, experts claim that random data should be written into the sectors several times, because forensic analysis can detect the previous magnetic residue if the magnetic bits are overwritten only once.
1.0 Purpose - The purpose of this procedure is to wipe all data from Target drives used in forensic casework in order to ensure that no cross contamination occurs between cases.
Wiping is a distinctly different operation compared to erasing. While erasing completely deletes all of your data on the given partitions or disks, wiping only deletes only those spaces and files on the hard drive that are of no use to the OS nor you.
What type of evidence can be found on a computer? Evidence can be found in many different forms: financial records, word processing documents, diaries, spreadsheets, databases, e-mail, pictures, movies, sound files, etc.
The general phases of the forensic process are: the identification of potential evidence; the acquisition of that evidence; analysis of the evidence; and production of a report.
A generic network forensic examination includes the following steps: Identification, preservation, collection, examination, analysis, presentation and Incident Response.
An easy way to think about data wiping is when a cook over-salts a dish. Instead of destroying the dish (your hard drive), the cook adds some starch (overwriting your data) to hide the salty taste (your old data). The end result is a delicious dish with an indistinguishable amount of salt.
Data wiping is the process of eliminating all of the data stored on a hard drive or other data storage device. Under normal circumstances, data that is deleted isn't actually gone for good. Instead, all the pointers and indexes that reference that file are simply removed.
They often work to match evidence to people or other known elements, such as vehicles or weapons. Most forensic science technicians who perform laboratory analysis specialize in a specific type of evidence, such as DNA or ballistics.
Explanation. Acquisition (without altering or damaging), Authentication (that recovered evidence is the exact copy of the original data), and Analysis (without modifying) are the three main steps of computer forensic investigations.
Data recovery and forensics software can recover deleted files (on Windows/NTFS) by looking for entries in the file table that have not been overwritten. If the entries are still in place, they will show the locations where the file was stored.
Still, if you've wiped your hard drive and really wish you hadn't, it's entirely possible that your data can be recovered. When data is deleted from a hard drive, it's not erased. Instead, the locations of the bytes that form the document, MP3 file etc. are removed meaning the data itself still exists.
No, the FBI cannot recover data from a drive that has been secure wiped if that hard disk drive was made in 1992 or later because of a fundamental change to how we wrote data to disks and the inclusion of the Secure Erase command which is completely effective.
DO turn off and unplug your laptop, keyboard, and monitor before cleaning. DON'T use Windex or glass cleaner – your screen isn't a window. Also, glass cleaners don't kill germs. DON'T use paper towels or other abrasive materials.
The most effective way to destroy a hard drive is to shred it. Similar to shredding documents and paper, shredding turns a hard drive into a million tiny pieces that can't be put back together again, therefore destroying and erasing the data forever.
You should always destroy hard drives or other electronic devices before recycling because there is no way to ensure that equipment sent for recycling will not be accessed by information thieves.
