Computer Forensics from the Cloud

Computer Forensics from the Cloud

Introduction

The appeal of personal computers especially to the business elites has been rising exponentially since the 80s. Well, while it is true the sole purpose of the device was to draw a parallel between business and communication some crime phalanx used it as a way of making ends meet showing its worst face in 2002 when computer related crimes hit a 67% mark. This twist of events necessitated the creation of a way to combat this ordeal – the idea of computer forensic to investigate cloud content was born around this time. This bid went milestones in solving these issues.

 

Relationship between computer forensic and the cloud

Computer forensic revolves around series of complicated techniques that involves thorough extraction, experimentation, documentation and presentation of data from the computers that will always create a feasible audit trail whereas cloud computing involves storage of data within the virtual environment – these roles are usually carried out by cloud service provider. With all our data free to commute within the virtual environment – cloud – it may not be easy to decipher when our data is prone to attack. Computer forensics play pivotal role in ensuring that no breach occurs to a particular network and in case it occurs they go a point yonder In collecting and analyzing data from the network traffic which will always serve as an evidence for a particular intrusion. However, network forensic tools such as wireshark or tpcdamp may be used to detect intrusions.

The process

There are standardized digital procedures that forensics will be required to comply with. The code focuses on procurement, examination, scrutiny and finally presentation of the data. The data is only limited to static data due to lack of effective tools to work with mobile data.

Techniques

In the event that one is susceptible to a computer crime, the following may have to be undergone:

Live analysis

A computer forensic uses special sysadmin tools or custom forensics to collect proof from the operating system: It is common especially while handling encrypted files, sometimes imaging of appropriate hard disk volume is done before the computer is turned off.

Cross-drive analysis

This technique uses the relationship of information embedded within several hard drives to detect vices on different social networks.

Steganography

This is a computing technique that involves concealing data within a picture. Forensic expert will extract the hidden picture and compare its original if available. A good deal of pornographic files has been recovered from

Deleted Files

Forensics have come up with a software that is facilitates restoration of deleted data. Physical files that mostly remain in the operating systems or file systems even on deletion can always be reconstructed from disk sectors using file carving techniques.

Stochastic Forensics

Stochastic capabilities are used to trace activities with questionable numerical artifacts. It is appropriate in data theft analysis.

Word wrap

Though the place of Computer Forensic is still questionable, there is no doubt that the venture has helped in reducing computer crimes within the cloud. Advent of better and more advanced techniques will surely help reduce this challenge by a great deal.
