Comprehensive approach to protecting data and the information system integrity

Abstract

The article discusses key information security principles, focusing on confidentiality, integrity, availability, traceability, and the DIE model (Distributed, Immutable, Ephemeral). Confidentiality emphasizes the importance of secrecy and controlling access to prevent sensitive information from misappropriation. Integrity ensures that data remains accurate and trustworthy, with measures to prevent unauthorized modifications. Availability highlights the necessity of reliable and timely access to data, even in the face of potential system failures or disasters, by implementing safeguards like backups. Traceability, or audit trails, ensures accountability by logging user actions, which is crucials for investigating suspicious activities or data loss. The DIE model presents a modern approach to information security. Distributed systems minimize the impact of attacks by avoiding a single point of failure and incorporating redundancies. Immutable systems maintain unalterable logs to quickly identify and address anomalies, preventing malicious actors from covering up their actions. Ephemeral systems differentiate between essential, long-term “pets” and disposable “cattle”, advocating for a flexible infrastructure that can easily adapt to new challenges and retire vulnerable legacy systems. This model enhances security by reducing the attack surface and ensuring that only necessary, secure systems are maintained.
