A DEFINITION OF CYBERSECURITY Cybersecurity refers to the body of technologies, processes, and practices designed to protect networks, devices, programs, and data from attack, damage, or unauthorized access. Cyber security may also be referred to as information technology security.

THE IMPORTANCE OF CYBER SECURITY Cyber security is important because government, military, corporate, financial, and medical organizations collect, process, and store unprecedented amounts of data on computers and other devices. A significant 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. Organizations transmit sensitive data across networks and to other devices in the course of doing businesses, and cyber security describes the discipline dedicated to protecting that information and the systems used to process or store it. As the volume and sophistication of cyber attacks grow, companies and organizations, especially those that are tasked with safeguarding information relating to national security, health, or financial records, need to take steps to protect their sensitive business and personnel information. As early as March 2013, the nation’s top intelligence officials cautioned that cyber attacks and digital spying are the top threat to national security, eclipsing even terrorism.

CHALLENGES OF CYBER SECURITY For an effective cyber security, an organization needs to coordinate its efforts throughout its entire information system. Elements of cyber encompass all of the following:

Network security: The process of protecting the network from unwanted users, attacks and intrusions. Application security: Apps require constant updates and testing to ensure these programs are secure from attacks. Endpoint security: Remote access is a necessary part of business, but can also be a weak point for data. Endpoint security is the process of protecting remote access to a company’s network. Data security: Inside of networks and applications is data. Protecting company and customer information is a separate layer of security. Identity management: Essentially, this is a process of understanding the access every individual has in an organization. Database and infrastructure security: Everything in a network involves databases and physical equipment. Protecting these devices is equally important. Cloud security: Many files are in digital environments or “the cloud”. Protecting data in a 100% online environment presents a large amount of challenges. Mobile security: Cell phones and tablets involve virtually every type of security challenge in and of themselves.
