Defense in Depth
Defense in Depth is a security strategy that uses multiple layers of protection to safeguard assets, information, or systems. Imagine a castle with walls, a moat, and guards—if one layer fails, others still offer protection. In practical terms, it means combining various security measures, like firewalls, antivirus software, and policies, to create a comprehensive defense. This approach reduces the likelihood of a successful attack, as intruders must overcome several obstacles. Ultimately, Defense in Depth enhances security by ensuring that if one defense is breached, others remain to protect against threats.

Defense-in-Depth is a security strategy that uses multiple layers of protection to safeguard assets and information. Instead of relying on a single security measure, this approach integrates various tools and practices, such as firewalls, encryption, and employee training, to create a comprehensive defense system. If one layer fails, other layers continue to provide protection, making it harder for threats to succeed. This method is commonly used in cybersecurity but can also apply to physical security and risk management, ensuring that there are several barriers to deter potential attacks or breaches.
