The good faith principle is a legal and ethical standard requiring all parties, including citizens and authorities, to act honestly, transparently, and reasonably during administrative or procedural interactions. In cybersecurity, this principle ensures that actions such as reporting vulnerabilities, handling data, or conducting investigations are performed with integrity and without malicious intent. Upholding good faith fosters trust, cooperation, and fair treatment, reducing the risk of abuse or misunderstanding. Violations of this principle can lead to legal consequences or loss of credibility, making it a cornerstone in both legal frameworks and professional conduct within cybersecurity and information governance.
