Defense in Depth (DiD)

Defense in Depth (DiD) is a security concept applied in various domains to implement protective measures in multiple layers or tiers. It is based on the idea that a single security measure or a limited set of measures is insufficient. Instead, multiple mechanisms are implemented at different layers to reduce risks and improve the level of cyber resilience of systems and business processes.

Examples of building blocks of a Defense in Depth strategy include firewalls, intrusion detection/prevention systems (IDS/IPS), antivirus and anti-malware software, access controls, encryption technologies, regular security audits, and employee training.

UEM supports Defense in Depth

A Unified Endpoint Management (UEM) solution can play an important role in a defense-in-depth approach because it helps IT professionals implement and manage security measures at multiple levels. A UEM system includes functions to set and enforce security policies, configure firewalls, implement access controls and encryption and many others.

The challenge is to strike the right balance between security and usability. The layers and measures implemented can increase complexity and affect user productivity. Careful planning, configuration, and regular review are essential.
