a proper analysis environment is the bedrock of any investigation involving evidence, digital or otherwise.
00:10
The analysis environment enables evidence to be analyzed and evaluated under safe and reliable conditions to preserve the integrity of the evidence.
00:18
Each organization has its own policies governing the details of the environment, but all must adhere to common best practices when analyzing visual evidence.
00:26
Systems using an analysis environment need the necessary storage and performance capabilities to run the tools and applications used to scrutinize of digital artifacts.
00:34
Because separate systems might be used for different purposes such as memory analysis, were image analysis
00:39
analysis. Environment may allow for several examiners to work in a multiple aspects of the analysis process at the same time on different systems to progress more efficiently.
00:48
Each analysis system should have honest Cerritos preloaded
00:52
and the tools thoroughly tested for literally
00:55
each told war application should include proper documentation, including how it works and how it might interact with or modify artifacts being analyzed.
01:03
Help ensure forensic validity. Each tool should have credibility in the field of forensics and produce repeatable results.
01:08
All methods used in the analysis need to be easily replicated by other examiners.
01:12
Good analysis tools do not need the cost of fortune and men you're available and no costs. However, any thoughts should be able to withstand the highest level of scrutiny in the courtroom.
01:22
Peter Evidence is fragile and easy to alter,
01:25
documenting all actions taken during analysis and finding that each step is critical.
01:30
Virtual machines are great foundation for analysis environments halo data to be analysed and rolled back, enabling analysts excuse multiple tests and use cases.
01:38
Virtual machines can be saved at various states. It can't be rebuilt or replaced at a moments notice. For instance,
01:45
when analyzing viruses arm our behavior, there is a risk of damaging the underlying systems. However, with virtual machines, the Marber can be tested and then the system can be reverted to a previous state and tested again.
01:57
These analysis test mints can be both relatively quickly without having require physical systems and hardware to do the job.
02:04
The analysis environment should be kept isolated from any networks or Internet connectivity unless absolutely required
02:08
isolation on only protects the network from dangerous, such as malware. It also protects evidentiary, a data from accidental corruption from external sources.
02:16
If analysis systems need to operate on the network. Proper security measures are needed to restrict access at the most granular level. Otherwise, he's network based service is or connections that are simulated locally and restrict external network or Internet access.
02:30
The golden analysis environment is to provide a safe and trustworthy setting for reviewing and analyzing data and other digital artifacts.
02:38
This can be achieved by validating, documenting and testing the environment and procedures thoroughly and repeatedly is was maintaining a high level of fidelity and flexibility in the environment in order to maximize results and enhance the analysis process.
