Digital forensics is the science of gathering digital evidence to solve crimes and for investigation purposes. It is the discovery analysts and reconstruction of evidence extracted from computer systems, computer networks, computer media, and computer peripherals that allow investigators to solve a crime. In today’s cyber age, evidence of several crimes lie in digital formats like emails chats, documents digital pictures pen drives mobile phones etc. The imaging recovery and analysis of such information is called digital forensics.
Technology is ever evolving and with new devices, software and encryptions being introduced everyday, specialized software and hardware to keep up with it is also being produced at a rapid pace. Hence, the scope of the Field is vast and constantly requires new resources. Yet, awareness levels in India are very low and education on law enforcement in these areas needs to be imparted.
Several new trends in the digital forensics industry involve new software for forensics over computers, PDA’s, mobiles, decryption, crime analysis software forensics over new devices and operating systems. Digital forensic investigations are performed in support of various objectives, including timely cyber attack containment perpetrator location and identification, damage mitigation and recovery initiation in the case of a crippled yet functioning network. New labs have been set up in every state of the country for the same purpose. With the increase in cyber led crimes today even major corporates are feeling the need to carry out forensics
The process of computer forensics often begins with gathering of evidence from computer media seized at the crime scene. Principle concerns with computer forensics involve imaging storage media, recovering deleted files, searching slack and preserving the collected information for litigation purposes.
Network forensics gathers digital evidence that is distributed across large scale complex networks. Often this evidence is transient in nature and is not preserved within permanent storage media. Network forensics deals primarily with in-depth analysis of computer network intrusion evidence. The current commercial intrusion analysis tools are inadequate to deal with today’s networked distributed environments.
Forensics is no longer confined only to government or government organizations with information going digital, even private companies are trying to fight cyber crime. It is an upcoming field and is likely to see immense growth in the following areas:
1) Research in Forensic hardware
2) Imaging softwares
4) Analysis Softwares
5) Ethical hacking
6) Cyber law
7) Forensic Investigator
Security companies deploy at least five people in every state for carrying out and supporting forensics and spreading awareness by means of training programs. This number can even go up to around 20 in very state. Then the government employs many forensic investigators.
Profound knowledge of computers, mobile phones, PDAs and similar devices lie the iPad, embedded devices and others is essential. Undertaking training in courses in information security, forensics softwares, hardwares, ethical hacking could give one an edge over the rest. A bachelor’s degree in engineering or science is every helpful as a science graduate has an overview of all the elements. However, this does not in any way mean that commerce or an arts graduate cannot take up digital forensics.
Digital forensics being a niche field, there is a shortage of professionals. The demand for such experts is high as there has been a tremendous rise in crime through digital communication – among terrorist to other transactions and regular crimes in the digital world. On average freshers can expect anything between Rs 12000 and Rs 20,000 per moth and about 10-20 per cent hike over programs and 50 per cent over networking jobs. Experienced people in the industry earn very high salaries. Also, as there is a profound shortage of forensic professionals abroad especially in countries like that the UK and the US salaries there could go to $100000 to.
1) IIIT Allahabad offers it as a masters course
2) Acharya Narendra Dev College and Jesus and Mary College University of Delhi
3) Institute of information Security , Mumbai.
4) Appin also runs this course as a part of its frontrunner programs at its centers across India.
