Basics of cyber security protecting the hardware systems, software programs and data your business relies on from external threats. Threats can come in the form of cyberattacks, hacks, viruses and malware or even physical attacks like burglaries and fires.
As a computer security specialist, you need to be aware of all these threats and how to defend against them. You’ll also need to understand how the different aspects of cyber security work together. This article covers the basics of cyber security, and is a great starting point for anyone who wants to start a career in this field.
The concept of cyber security has become increasingly important as organizations transmit unprecedented amounts of sensitive information across networks and devices. Much of this information is confidential, financial or personal, and its unauthorized access or exposure can have negative consequences.

To combat this, organizations need to use a variety of cyber security measures, including electronic passwords and encryption. Moreover, continuous system monitoring is critical to early detection of any potential security threats. This allows you to take action before a breach occurs and limit the damage.
The three core principles of cyber security are Confidentiality, Integrity, and Availability. This triad has been the standard for computer security since the first mainframes were used. Confidentiality means that only authorized parties can access sensitive information and functions, for example, military secrets. Integrity is ensuring that the information cannot be altered or tampered with, for example, changing your bank account number to stop your paychecks from automatically depositing into your account. Lastly, availability is making sure that the information and functions are available on demand. This could include putting processes in place to back up data regularly and increasing bandwidth to prevent bottlenecks.
