Cybersecurity is the practice of defending computers, networks, and data from malicious electronic attacks. It is often contrasted with physical security, which is the more traditional security practice aimed at controlling access to buildings and other objects in the real world.

Although there are plenty of high-tech physical security techniques, and sometimes physical and cybersecurity are joined together in the organizational chart to prevent malicious attack both electronically and physically. Cybersecurity focuses on protecting assets from malicious log-ins and code, not burglaries as people assume. Cybersecurity includes the following types;

Network security

It prevents and protects against unauthorized intrusion into corporate networks.

Application security

It makes applications more secure by finding and fixing vulnerabilities in application code.

Information security

It sometimes also referred to as data security. It keeps data secure from unauthorized access or alterations, both when it’s being stored and when it’s being transmitted from one machine to another.

Operational security

Often abbreviated as OPSEC, it is a proc ess by which organizations assess and protect public data about themselves that could, if properly analyzed and grouped with other data by a clever adversary, reveal a bigger picture that ought to stay hidden.

Some aspects of disaster recovery are also considered to lie under the cybersecurity umbrella; in particular, techniques to remediate widespread data loss or service outages as a result of a cyberattack are part of the larger cybersecurity discipline.



Any cybersecurity framework will provide detailed direction on how to implement a five-step cybersecurity process:

  • Identifying vulnerable assets within the organization
  • Protecting assets and data, and taking care of necessary maintenance
  • Detecting breaches or intrusions
  • Responding to any such breaches
  • Recovering from any damage to systems, data, and corporate finance and reputation that result from the attack



In today’s connected world, everyone benefits from advanced cyber defense programs. At an individual level, a cybersecurity attack can result in everything from identity theft, to extortion attempts, to the loss of important data like family photos. Everyone relies on critical infrastructure like power plants, hospitals, and financial service companies. Securing these and other organizations is essential to keeping our society functioning. The purpose of cybersecurity is to;

  • help prevent cyberattacks
  • data breaches
  • identity theft
