Cyber Security Introduction
"Cybersecurity is primarily about people, processes, and technologies working together to encompass the full range of threat reduction, vulnerability reduction, deterrence, international engagement, incident response, resiliency, and recovery policies and activities, including computer network operations, information assurance, law enforcement, etc."
Cybersecurity is the protection of Internet-connected systems, including hardware, software, and data from cyber attacks. It is made up of two words one is cyber and other is security. Cyber is related to the technology which contains systems, network and programs or data. Whereas security related to the protection which includes systems security, network security and application and information security.
It is the body of technologies, processes, and practices designed to protect networks, devices, programs, and data from attack, theft, damage, modification or unauthorized access. It may also be referred to as information technology security.
We can also define cybersecurity as the set of principles and practices designed to protect our computing resources and online information against threats. Due to the heavy dependency on computers in a modern industry that store and transmit an abundance of confidential and essential information about the people, cybersecurity is a critical function and needed insurance of many businesses.
Why is cybersecurity important?
We live in a digital era which understands that our private information is more vulnerable than ever before. We all live in a world which is networked together, from internet banking to government infrastructure, where data is stored on computers and other devices. A portion of that data can be sensitive information, whether that be intellectual property, financial data, personal information, or other types of data for which unauthorized access or exposure could have negative consequences.
Cyber-attack is now an international concern and has given many concerns that hacks and other security attacks could endanger the global economy. Organizations transmit sensitive data across networks and to other devices in the course of doing businesses, and cybersecurity describes to protect that information and the systems used to process or store it.
As the volume of cyber-attacks grows, companies and organizations, especially those that deal information related to national security, health, or financial records, need to take steps to protect their sensitive business and personal information.
