Nowadays crimes are performed with new tools and technologies. But as the techniques of performing illegal activities are increasing. Digital forensics has also evolved at an alarming rate.

In the earlier days of digital forensics, it failed to solve most of the cases. But as the time flies there are a lot of improvements happened in the field of digital forensics. Let’s take a look at the evolution of digital forensics.

## Evolution of Digital Forensics
**Data Emergence in 1970 -** It is the time when the types of computers are mainframes and minicomputers. It is the beginning of giving value to the digital data.
**Expansion of Computers 1980 -** When there are personal computer starts increasing then every digital forensics expert started analyzing computer systems to collect evidences.
**Techniques Establishment 1990 -** Here the cybersecurity experts and law enforcement agencies started to follow the methodology to investigate digital crimes.
Increasing of cybercrimes Because of the Internet Late 1990 - As the Internet started capturing the world, more fraud, theft, and other digital crimes became challenging to solve for the experts.
**Standardization Early 2000 -** It is the emergence of the International Association of Computer Investigate Specialists (IACIS) and the National Institute of Standards and Technology (NIST). They started providing the guidelines and best practices for digital investigation.
**Digital Media and Mobile Devices Mid 2000 -** Because of the mobile devices and digital media storage devices digital forensics took a boost. Cyber analysts are also started focusing on how to find evidences from devices, USBs, cell phones, and so on.
**Impact of Cloud Computing Late 2000 -** The introduction of cloud computing comes up with new challenges for digital forensics. Now investigators had to be aware of the decentralized data storage.
**At Present -** Now digital forensics also performing research on IOT and blockchain security to figure out the ways of getting insights from them.

This is the time to time upgradation of the digital forensics. Now, let’s to move to the advancement of the collection and presentation of evidences.
