ACL (Access Control Lists) is used by the techies to restrict and limit the actions of various users when the access to NSF files in Domino Server are taken into account. The very first step with which the Domino Server administrators proceed after a new user account is registered, is an implementation of the ACL factors on the account. This action turns into a disadvantage when it comes to the forensic investigation of the Lotus Notes NSF files that have ACL encryption enabled or have been protected by the local security.
Manual decryption of the ACL encryption enabled NSF files are very tedious and time – consuming. To check that whether the local NSF security has been applied on the NSF file and it is ACL encrypted, just double-click on the NSF file. Confirmation of the same can be achieved if the following error pops ups: –
“Local Access Protection”
This indicates that the NSF file is encrypted. Investigations can be more challenging and tiring when it comes to understanding the anatomy of such NSF files. A detailed R & D by the experts have shown that most of the investigators have been asking for a software solution with the following potential: –
The SECURASE advanced forensic tool which can be used to remove local security. The tool can be very conveniently used in situations where the following error messages pop up while accessing the NSF file: –
“You are not authorized to access that database”
or
“You are not authorized to perform that operation”
System Requirements by the tool to Open Encrypted NSF File: –
Operating System: – Windows 8.1 and below Windows versions
Processor: – 1 GHz
RAM: – 512 MB
Hard Disk Space: – 5 MB
NOTE: – Installation of Lotus Notes 9.0 or any below version is mandatory
The sophisticated job to remove local NSF security, if not carried out with proper strategy and smartly, may lead to complete breakdown and corruption of the NSF file. Thus, experts have been suggesting tools like Securase that has been developed using advanced algorithms.
