== History ==
+
 
+
During the 1990s, it became a [[best practice]] to capture a [[Tools:Memory_Imaging|memory image]] during [[Incident Response|incident response]]. At the time, the only way to analyze such memory images was using [[strings]]. Although this method could reveal interesting details about the memory image, there was no way to associate what data came from what program, let alone what user.
+
 
+
In the summer 2005 the [[Digital Forensic Research Workshop]] published a ''Memory Analysis Challenge''. They distributed two memory images and asked researchers to answer a number of questions about a security incident. The challenge produced two seminal works. The first, by [[Chris Betz]], introduced a tool called [[memparser]]. The second, by [[George Garner]] and [[Robert-Jan Mora]] produced [[KnTList]].

At the [[Blackhat (conference)|Blackhat Federal]] conference in March 2007, [[AAron Walters]] and [[Nick Petroni]] released a suite called [[volatools]]. Although it only worked on [[Windows XP]] Service Pack 2 images, it was able to produce a number of useful data. [[volatools]] was updated and re-released as [[Volatility]] in August 2007, and is now maintained and distributed by [https://www.volatilesystems.com/ Volatile Systems].

Cell Site Analysis (CSA) is the technical discipline of using mobile telephony signals and network data to triangulate and identify the relative geographic position of a device.

Cell site analysis is considered a highly intrusive surveillance technique and as such normally deployed only in sensitive or serious criminal investigations.

The technique can assist in demonstrating the co-location (meeting) of individuals, their movements over time, proximity to a scene of crime, and to verify the any defence alibi evidence.
