The internet today is a treasure trove of information and technological advancement has made it accessible from every nook and corner of our country. Development of sophisticated and highly refined search engines has made information available to anyone and everyone. However, this largest and richest source of information has also increased the risk of cyber crimes and loss of privacy. The explosion in the use of internet has also seen an alarming rise in the number and magnitude of internet related crimes.
Cyber crime refers to all crimes which are committed using communication devices like the internet, social media, mobile or telephone. It involves activities like:
Illegal access to or interception of computer data
Unauthorized damaging or deletion of computer data
Unauthorized interference with computer system
Misuse of IT devices
These activities may be against an individual, an organization or against a government.
What are the different types of cyber crimes
The advancement of technology and increase in the use of internet has resulted in cyber crimes taking different forms such as:
Hacking- Unauthorized intrusion into a computer system
Denial of service- Depriving the victim of the services he is entitled to access
Virus attack- Using malicious software to attack the victim’s system
Software Piracy- Illegal copying of genuine softwares
Frauds related to credit cards and bank accounts
Net extortion – involves copying an individual’s or organization’s confidential data to extort money from the victim
Phishing- It is a technique used to extract confidential data like password etc
Spoofing- It refers to getting into one’s computer on a network to pretend to have the identity of another computer.
Cyber stalking- Using the internet to stalk someone
Cyber defamation- Sending defamatory material through mails or posting defamatory material on the net
Salaami Attack- This involves making illegal, minor and unnoticeable changes through computers. For example, a cyber criminal may deduct Rs 10 from thousands of accounts of a bank without most account holders noticing or complaining to the bank about the deduction. The criminal may steal a huge amount through such a crime, without the crime even coming to notice.
A professional and well done cyber investigation should be able to not only identify the source of the intrusion but should also be able to safeguard your system from future attacks. It should involve collection and examination of physical as well as digital evidences to uncover details like where and when and how the intrusion or crime occurred.
It should be able to determine what data was compromised and whether digital evidence was tampered with. Further, the investigation should also be able to recover the original data, and also suggest an effective security plan.
A professional cyber investigation involves a range of investigation activities, requiring the services of different experts, like IT experts, forensic experts, legal experts, investigation officers etc. It may require a combination of computer forensic expertise with traditional investigative methodology, like conducting interviews and surveillance. This is essential to catch the criminal and identify people in the organization who might be involved in the crime.
A cyber crime investigation may involve the following procedures:
Vulnerability Assessment tests- A vulnerability assessment test is aimed at testing and analyzing the client’s network and computer systems in order to identify vulnerabilities in the system. Such a test would bring forth weak spots that require updating and up gradation.
Penetration Testing- This involves both internal and external penetrations testing. External testing tests the network’s Internet-facing assets to protect it from external attacks by outsiders. Internal testing, on the other hand, is aimed at testing the overall security level of the IT infrastructure of the organization from within its network. A common belief is that threats to networks and data often originate from outside an organization. This, however, is more of a myth than a reality. Studies have often shown that such threats are as common from within the organization, as they are from outside sources. This is why, both internal and external penetrations testing are considered to be equally important.
Application Security Testing- With applications becoming more and more common, it has become extremely important to protect the IT infrastructure of the organization from cyber threats and vulnerabilities arising out of the apps. Application security testing is aimed at evaluating the control mechanisms put in place to limit users’ access to data and make them fully secured to use.
Policy and Procedure Review- A strong, well-written network security is one of the most effective and essential tools to ensure security of a network.
