Question: In these weeks readings, we learned about the CIA Triad and how each exhibits dependance on the other. Give examples of how failure of one security property (confidentiality/integrity/availability) can lead to the failure of the others. How does a password or authentication relate to this situation? Make sure to cite at least one reference using APA guidelines. Wikipedia, blogs and about.com are not credible sources. You should be using scholarly articles found in the Library Databases. Minimum 250 words.

Paper For Above instruction

The CIA Triad — Confidentiality, Integrity, and Availability — is fundamental to understanding information security. These three principles are interconnected, and the failure of any one can compromise the entire security framework. Analyzing how the failure of one property causes the collapse of others offers insight into maintaining robust security measures.

One illustrative example is the breach of confidentiality leading to the failure of integrity and availability. For instance, if sensitive data is leaked due to inadequate confidentiality controls, malicious actors may alter or corrupt this data, thereby compromising its integrity (Pfleeger & Pfleeger, 2015). Such a breach often results in the data becoming unreliable, which directly impacts decision-making processes and operational functionality. Moreover, the exposure of data can impair availability if the breach involves data destruction or denial-of-service attacks that render information inaccessible (Whitman & Mattord, 2018). For example, a compromised medical records system that exposes patient data may lead to system shutdowns to prevent further leaks, thereby disrupting access to vital health information.

Conversely, failure in availability, such as a denial-of-service attack, can hinder confidentiality and integrity. When systems are overwhelmed by malicious traffic, legitimate users cannot access services, which could prevent authentication processes from occurring (Kizza, 2017). This disruption hampers the system’s ability to verify users effectively, potentially allowing unauthorized access when the system is restored or leading to the use of fallback authentication methods that may be less secure.

Authentication plays a pivotal role in anchoring these principles. Passwords, biometrics, or multi-factor authentication are mechanisms to ensure that only authorized users access data, thus preserving confidentiality. However, weak or compromised authentication measures can undermine confidentiality and allow unauthorized users to alter data (Hæmmerli, 2020). For example, if passwords are weak or stolen, an attacker can access sensitive information, manipulate data, or disrupt system availability through malicious activities. Therefore, robust authentication methods are essential for maintaining the integrity and availability of information systems.

In conclusion, the interdependence of the CIA Triad emphasizes that a failure in one area can cascade, jeopardizing the entire security posture. Proper authentication mechanisms are crucial in preventing such failures and ensuring that confidentiality, integrity, and availability are sustained (Pfleeger & Pfleeger, 2015). Strengthening one aspect inherently supports the others, underscoring the need for comprehensive security strategies.
