Jordan Hrycaj of 7Safe, recently acquired by PA Consulting, was up next to talk about what he described as ‘ad-hoc’ search – for use in digital forensics or digital discovery applications. The application he described can be used to search the hard disks of suspect PCs or servers for information such as credit card numbers extremely quickly, working at a low level to avoid leaving any impression on the data (i.e., no file timestamps are altered) and usually working on live systems. This system is command line based, tiny in size and portable across operating systems and is an impressive way to cut down the likely candidates for a data security breach. It was fascinating to hear about a way to search that doesn’t depend on indexing, and the compromises made for performance reasons (i.e., regular expressions can be used but without wildcards).

Thanks to both speakers and to all who came to hear them. We already have some more talks lined up so we expect the next Meetup to be sooner rather than later!

C Spencer are known for their innovative and modern approach – they’re even building their own green power station on a brownfield site in Hull. It’s thus not surprising that they chose cutting-edge open source technology for search: tracking and managing documents correctly is extremely important to their business.

They’ve also released an ‘Express’ (i.e., free but feature limited) version of Microsoft Search Server. We’re going to take a deeper look at this soon.
