Security measures are deployed at various levels, such as network, application, and data, ensuring that breaking one layer leads only to another, more difficult layer to bypass. **Examples**: - **Firewall** at the network perimeter. - **Encryption** for sensitive data storage. - **User access controls** and **multi-factor authentication** (MFA) for system access. 2. **Minimizing Impact of a Breach**: - If an attacker compromises one layer, other layers continue to provide protection, minimizing the overall impact. **Examples**: - After gaining unauthorized access to a system, the attacker encounters **intrusion detection systems (IDS)** that alert administrators before further damage is done. 3. **Time for Countermeasures**: - The multi-layered approach gives security teams time to respond to threats and deploy new or updated security measures if one layer is breached. **Examples**: - **Incident response teams** can react to alerts from compromised layers, isolating affected areas while reinforcing other parts of the system. 4. **Reduced Single Points of Failure**: - By having multiple defenses, the risk of a single vulnerability causing a full-scale breach is greatly reduced. **Examples**: - **Antivirus software**, **network segmentation**, and **data backups** work in tandem to protect assets even if one line of defense fails. ========================================================================================================================================== --Risk: Key Concepts-- **Definition**: Risk refers to the potential for loss or damage to an information system due to an adverse event or vulnerability.
