Ever since humans have started to live in a community, the need for safety has grown more. Everyone wants to stay safe and feel protected. It not only comes to humans but also to the systems we are working in. Transparency is one thing, but staying safe is another, with the advancements in the world of information security, the internet is accessible to all and sundry, from computers to laptops, mobiles, handheld devices, gadgets the access to the Internet is easily available to all.
It is not only there as a mean of communication, but now it is being used for ecommerce, trades, the transaction of money and funds, storage of data in the form of clouds, transferring of information and for minting the smooth and wireless functioning of multiple units in the offices and enterprises.
Now all of this means that the internet is available everywhere from offices to homes, and that means that apart from its benefits, there can be other potential harmful threats to this all system that are the security breaches and vulnerabilities. It is when the need for cyber forensics and information security arises.
Not only can it save from computer crimes, but also helps to analyse, recover and identify many units of the systems and to keep them protected all the time. Also, it can be helpful in formulating and identifying legal audit trails when in need. It can also keep the systems and people safe from hacking and over evil crimes that they can easily fall a trap into.
There are many methods of ensuring the practices of cyber forensics and information security, and not all of those can be discussed here; therefore only a few of them are highlighted in this section.
For example; in this regard, some of the common techniques are; cross-drive analysis that can be used for any anomaly detection at multiple drives or places.
Another important method is the live analysis in which the internal tools are used to examine the system, some of the key benefits of this technique are to identify encrypting file system, and that can be used for live acquisition even before the computer shuts down.
One of the most common and well-known methods of all is to recover deleted files. File carving is one of the most practised methods of all time.
