Performing Forensic delete

Post by subbuvin »

When I want to delete a file so that it is hard to recover that file again by forensic methods, I would overwrite the file numerous times with random data and then unlink the file. Forensic deletion of data from the database could also be done the same way. Is there a specified method for deleting data from the texis database so that it is hard to extract information forensically from it once they are deleted? How easy is it to perform a forensic delete on texis database?

If you are deleting the entire database then you can use the same method with the database files. If you want to do a specific record you could update it with random data of the same length as the original however many times you wanted before deleting the record.

So, will I be overwriting the same location where the original data resided in the first place?
Thanks in advance,

Yes, if you update the record with an equal or smaller size data. If you update the record with more text than already existed the record may move somewhere else.
