What is Cyber Security?
Cyber Security is a process where people, technology, and programs make a safeguard or blockade against the threats and dangerous elements in the cyber world. Simply cyber security is the program in phones or other devices to safeguard them from attacks and threats. Cyber security is a process where technologies, people, and functions are involved in creating a blockage for cybercrimes.. Since technology is evolving day by day, the data are now kept in virtual form. So it gives the attacker chance to attack it. So it just disrupts the data or steals the data from other devices.
These crimes done in the cyber world are called cybercrimes. Cybercrimes include hacking, illegal data mining, virus, and many more. Also, these all are very harmful to device and user data. So to stop all these kinds of crimes strong cyber security is installed in the system. This cyber security stops the chances of cybercrimes.
More About It
Moreover, this cyber security is very important in all companies. This would help in reducing the chances of the threat in the virtual system. However, there is much importance to cyber security. Some of the major importance of it is as follows.
- It is very helpful in protecting data and systems from external and internal threats. Moreover, it would make your system secure so that no internal or external threats would cause harm to it.
- Also, it provides processes like spying and tracking. This would help to track down the culprit and would be very helpful in reducing cybercrimes. You also trace the culprit’s location and system which later on can be useful as a piece of evidence.
- Moreover, it would provide a safeguard for your system and the data available. So this cannot be misused for evil deeds.
- However, you can learn many modules of computer science in cyber security. You would get great knowledge of it which is very helpful in the future. Also, you can get many good jobs after cyber security.
Types of Cyber Security
Cyber Security’s main objective is to create blockage in the system. So it will spy, track and remove the malfunctions in the system. However, there can be many systems, it can networks, channels, and many more. So to get complete knowledge of the concept of system and cyber security, you must know about the types of cyber security. Some of the major types of cyber security are as follows.
Application Security
This type of security is installed during the development stage of the application. Also, it is not just for any system application. But also for mobile applications and websites. The major importance of this security is to manage the development, deployment, maintenance, and upgrade of the application from any security threat. Moreover, this is the major of any initial stage of application. This application security is using different methods for security in the system
- It uses Parameter Validation so that no external thereat would enter the application. Moreover, it will ask for different parameters to enter into the application. This parameter validation can be seen in many mobile applications you use. It will make your device very secure.
- Then it is Session Management, where there is a certain time limit given to pages. Moreover, when the time limit is over, the page restores automatically. This will reduce the time of threat in a system to do any mischief activities.
- Then finally it is the User Authentication, under this the application will ask for user approval from another device or system to enter the application. It is most clear while logging in to the google account. So this helps in reducing the threats.
Network Security
Network Security is the blockage of the threats in the network of the system. The networks can be internal or external. So this part of cyber security will you to prevent the threats of internal and external networks. Moreover, there are different parts where network security will help. These all are as follows.
- It provides security from thefts, where some sort of threat enters the network for stealing data. This theft is very common in government networks, where some confidential information is at risk. So they have to make strong network security for confidential files, and teams of cyber security are very important.
- Network security provides the feature of access denial in the system when it detects any threats and malfunctions. This will directly stop the threat which is trying to enter the system.
- The new kind of heist is data heist, it has become a major problem in many networks. So network security provides strong alerts for data breaches. This will help the network to stop threats directly in the network. Moreover, it will help with different internal and external threats.
Disaster Security
Disaster Security helps the system to recover if any threats successfully breach the program. When threats steal the data or export malfunction the system, disaster management will do its work. So, it will try to recover as much data as it can. Also, it will trace the sign of malfunction and try to remove it from the system. Therefore, disaster management is very important in the system for better productivity of the work. Disaster security covers different areas in the system. They are as follows.
- The first one is risk assessment where the various areas where threats are more must-have more security. This will help in reducing the risks of threats.
- Also, it has the feature of risk analysis, which will help in the area where more disasters are done, if something enters the system. This will help to know about risk and reduce it further.
And, the final is data recovery, under this when thereat has done disaster. This will help in further data recovery. This is very important in safeguarding the system in times of caution. So every firm must install it under their system for better cyber security.
History of Cyber Security
The history of Cyber Security starts with a great computer engineer ‘Bob Thomas’. In 1979 computer networks have just started and the virtual data storing system is non-existing. But there was a huge line of networks, where data are transferred. This can give rise to cybercrime. So Bob made a program called ‘Creeper’. Basically, it was a worm malware, which he injects into the system. It travels from different networks with the message “ I am a creeper, catch me if you can’.
Now after a year, Ray Tomlison inventor of e-mail identifies the creeper in the system. Now he makes some kind of program in the system. This program followed the creeper and removes it from the system. So it becomes the first antivirus that not only traces the malware but also removes it. Then it becomes the first antivirus in the world. During this time crime rate was very low, almost non-existing. However many programs were made just for future possibilities. Because everyone knows about it very well. This was the incident from where the idea of cyber security and antivirus started. Now from here, new programs start to test cyber security. Moreover, much research was done to make great cyber security. So, in this era, there is great cyber security. The companies like Cisco, and Amazon are providing securities against cybercrime. However, cyber crimes are increasing at a high rate. Even in democratic politics, cyber involvement plays an important role. The incident of Cambridge Analytica has just proved it our cyber security is very much flexible towards the culprit itself.
