The CIA Triad is an information security concept that consists of three core principles, (1) Confidentiality, (2) Integrity and, (3) Availability. These core principles become foundational components of information security policy, strategy and solutions. Cybersecurity professionals and Executives responsible for the oversight of cybersecurity programs should have a deep understanding and appreciation for each of the three core principles.
Ultimately, all vulnerabilities and risks should be evaluated based on the threat they pose to one or more of the CIA Triad core principles. In addition, all security controls, or countermeasures, should be evaluated on how well they address the core principles of the CIA Triad.
This core security principle is defined as the ability to restrict unauthorized subjects from accessing data, systems, objects or resources. Imagine an employee punches the timeclock and goes home for the evening but forgets to shut down or lock their computer. Even worse, they are still logged into the client database that contains all sorts of Personally Identifiable Information (PII) like your client’s names, addresses, and social security numbers. What happens if the janitorial service shows up to clean the office space and one of the cleaners notices the unlocked computer and helps themselves to the valuable info? This example illustrates the importance of Confidentiality.
There are many cyber-attacks used to violate confidentiality including, social engineering, theft of credentials or passwords, eavesdropping and network sniffing. Here are a few controls that you should consider incorporating into the program:
This core security principle is defined as the ability for data and information to retain truth or, accuracy and be intentionally modified by authorized users only. Imagine a patient under the care of doctors and nurses at a hospital. The patient requires 100mg of medication every six hours. What happens if the nurse accesses the patients’ medical records and the 100mg has been modified (with malicious intent or by accident) and now reads 1000mg? This example illustrates the importance of integrity.
There are many cyber-attacks used to violate integrity including, computer viruses, malware, logic bombs, database injections and altering system configurations. Your cybersecurity program should absolutely work to promote integrity and defend against these attacks. Here are a few controls that you should consider incorporating into the program:
This core security principle is defined as the ability to grant authorized users uninterrupted access to systems and information. Imagine logging into your computer on Monday morning. You are refreshed from the weekend, ready to work and conquer the world. Then suddenly, a message flashes across your computer screen. The message explains that your computer and everything on it has been encrypted by ransomware, and you must pay a fee to receive the decryption key and resume regular work activities. You no longer have access to email, customer records, financial records, etc. What would you do if the applications and data on your computer were no longer available to use? This example illustrates the importance of Availability.
There are many cyber-attacks used to violate availability including, computer viruses, malware and denial of service (DoS). There are also circumstantial events that violate availably such as hardware failure and natural disasters. Your cybersecurity program should absolutely be influenced by the availability principle. Here are a few controls that you should consider incorporating into the program:
As one can see, the core principles of the CIA Triad (Confidentiality, Integrity and Availability) are simple information security concepts that when properly applied to policy and program creation can have a real meaningful impact our ability to stay safe and protected.
