A user should only have the minimum level of access necessary to do their job. This limits the "blast radius" if an account is compromised. 5. The Aftermath: Incident Response
The Invisible Shield: Decoding the Fundamentals of Information Systems Security
Guaranteeing that data is accurate and has not been tampered with. If a bank balance changes without a transaction, the integrity is blown. Fundamentals of information systems security
At the heart of every security policy lies the . These three concepts are the benchmark for any secure system:
Technology alone cannot save a system. Security starts with . This involves: A user should only have the minimum level
Ensuring that systems and data are ready for use when needed. A secure system is useless if it’s crashed by a Denial-of-Service (DoS) attack. 2. The Human Element: Policy and People
Who gets in, and what can they do? Fundamentals dictate two key rules here: These three concepts are the benchmark for any
