Essay on Cyber Security
Answers
Answer:
Cyber security can be defined as the protection of systems, networks and data in cyber space. It refers to the preventative methods used to protect information from being stolen, compromised or attacked.
Cyber security is a complex issue that cuts across multiple domains and calls for multi-dimensional, multi-layered initiatives and responses. It has proved to be a challenge for governments because it involves various ministries and departments. It is more difficult primarily due to the diffused and varied nature of the threats and the inability to frame an adequate response in the absence of tangible perpetrators.
Cyberspace has expanded dramatically in its brief existence due to rapid development of information technology (IT) and commercial applications associated with it. Advances in information and communications technologies have revolutionized the scientific, educational and commercial infrastructures developed by the government.
The IT infrastructure has become an integral part of the critical infrastructure which supports national capabilities such as energy, power grids, telecommunications, emergency communication systems, financial systems, defence systems, space, transport, land records, public essential services and utilities, law enforcement and security and air traffic control networks, to name a few.
All these infrastructures increasingly depend on relay data for communication and commercial transactions. The operational stability and security of critical information infrastructure is vital for the economic security of the country.
The evolving nature of the telecommunications infrastructure poses further challenges. The expanding wireless connectivity to individual computers and networks is making determination of physical and logical boundaries of networks increasingly difficult. The increasing inter connectivity and accessibility to computer based systems that are critical to the country’s economy are adding to the risk.

Future wars will not be like traditional wars which are fought on land, water or air. when any state initiates the use of internet-based invisible force as an instrument of state policy to fight against another nation, it is called cyberwar’.
It includes hacking of vital information, important webpages, strategic controls, and intelligence. In December 2014 the cyberattack a six-month-long cyberattack on the German parliament for which the Sofacy Group is suspected. Another example 2008 cyberattack on US Military computers. Since these cyber-attacks, the issue of cyber warfare has assumed urgency in the global media.
Conclusion
Today due to high internet penetration, cybersecurity is one of the biggest need of the world as cybersecurity threats are very dangerous to the country’s security. Not only the government but also the citizens should spread awareness among the people to always update your system and network security settings and to the use proper anti-virus so that your system and network security settings stay virus and malware-free.
