Defense In Depth
Defense in Depth is a cybersecurity strategy that employs multiple layers of security controls and countermeasures throughout an information system to protect against threats. It ensures that if one layer fails, subsequent layers provide additional protection, reducing the risk of a single point of failure. This approach is fundamental in designing resilient systems that can withstand various attack vectors.
Developers should implement Defense in Depth when building applications or systems that handle sensitive data, such as financial, healthcare, or personal information, to mitigate risks from breaches and attacks. It is crucial in high-stakes environments like cloud infrastructure, IoT devices, and enterprise networks, where a single vulnerability could lead to significant damage. By layering defenses, developers can enhance security, comply with regulations, and build trust with users.
