Cyber Attacks Definition
According to the Practical Law Company, Whitepaper on Cyber Attacks, conducted by hklaw.com, the definition of Cyber Attacks is as follows: The definition has three distinct factors: [1] Attack or an illegal attempt to [2] gain something from a [3] computer system. Generally speaking, a system is a collection of units that work collectively towards a common goal. Thus, whether it is a single or a collection of computers – offline or online (websites/intranets), it is a system as they work to facilitate something or the other. Even a single computer has many components that work together for a common goal and is called a computer system. The main factor is illegal access to such a system. The second factor is the target system. The final factor is the gains to the attacker. It should be noted that illegal access must have the motive to compromise the target system in a way that the attacker gains something, such as information stored in the system or total control of the system.

What are the types of Cyber Attacks?
There are many methods of Cyber Attacks, from malware injection to phishing to social engineering to the internal stealing of data. Other advanced but common forms are DDoS Attacks, Brute Force attacks, hacking, and holding a computer system (or a website) for ransom using direct hack or Ransomware. Some of them have been listed below:
Gaining, or attempting to gain, unauthorized access to a computer system or its data.Disruption or denial of service attacks (DDoS)Hacking a website or mal-facing the siteVirus or malware installationUnauthorized use of a computer for processing dataInappropriate use of computers or applications by employees of a company in a way that harms the company.
The last one – employees’ inappropriate use of computers or apps – could be deliberate or due to a lack of knowledge. One has to figure out why an employee, for example, tried to enter the wrong data or access a particular data record that one was not authorized to change. Social engineering could also be a cause whereby an employee deliberately tries to hack into the database – to help a friend! The employee was befriended by a criminal and is emotionally forced to obtain innocent data for the new friend. While we are here, it is also advisable to teach the employees about the dangers of public WiFi and why they should not use it for office work.

Cyber Attacks Response
Prevention is always better than cure. You must have heard this several times. The same applies to the field of IT when it comes to protection against Cyber Attacks. However, assuming that your computer(s) or website(s) were attacked, even after taking all the precautions, there are certain common general response steps laid down: Please read the whitepaper mentioned under the References section for exact and detailed information on responding the legal way.

Prevention of Cyber Attacks
You might already know that there is no 100% foolproof method to counter cybercrime and cyber attacks, but still, you have to take as many precautions to protect your computers. The primary things to be done are to use good security software that scans for viruses and looks for different types of malware, including but not limited to ransomware, and stops it from entering the computer. Mostly these malicious codes are injected into your computers by visiting or downloading things from non-reputed websites, Drive-by downloads, and compromised websites that display malicious advertisements, also known as Malvertising. Along with the antivirus, you should use a good firewall. While the built-in firewall in Windows 10/8/7 is good, you can use third-party firewalls stronger than the default Windows Firewall.

Employees should not be able to plug in Flash drives or their Internet dongles into the USB. The company’s IT department should also keep a watch on all the network traffic. Using a good network traffic analyzer helps prompt attendance to strange behaviors arising out of any terminal (employee computer). Read: Best Cybersecurity Practices for Small Business. For protection against DDoS attacks, the website is better mitigated to different servers instead of being hosted simply on a single server. The best method would be to have a mirror constantly up using a cloud service. That will greatly reduce the chances of a DDoS being successful – at least not for a long time. Use a good firewall like Sucuri and take some basic steps to protect and secure your website. Here are a few useful links that display real-time digital hack attack maps:
