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.
