An Avant-Garde Way for Implementing Defense In-Depth (DiD) for Your Organization
What is Defense-in-Depth
Organizations implement a defense-in-depth cybersecurity approach by deploying a series of security tools and measures in a layered fashion to protect valuable information and systems. The US military developed this security approach as a policy and defense method to ensure that organizations are not “blindsided by unexpected threats.” In this instance, if one security mechanism fails, a cybercriminal will still face other security layers, making it arduous to execute an attack.
Defense-in-depth mirrors the medieval castle approach that obstructed adversaries using a series of methods, such as the moat, draw-bridge, multiple walls, towers, and battlements. Organizations can learn invaluable cybersecurity lessons from the castle to secure sensitive information and systems that are consistently prone to frequent and sophisticated attacks.
Standard Elements of Defense-in-Depth
The figure below shows some of the essential defense-in-depth elements.
From the illustration, companies can apply a layered security approach from the lone endpoint device connected to a network, to data stored in servers.
- The network security layer is the first line of defense that requires security mechanisms, such as firewalls, demilitarized zones, data loss prevention through intrusion detection and prevention (ID/PS) systems, network component patching, network sniffers, port scanners, and vulnerability scanners
- Platform layer features measures such as antivirus programs, patching, security specifications for systems, access management, and port scanning
- The application layer requires security solutions such as secure coding practices, security specification, web application firewall, sandboxing, and reliable web gateway services
- Data layer security measures include data encryption, enterprise user access, and identity management
- The response layer involves incident response planning, security monitoring, intrusion detection, and remediation
The incident response planning anticipates and set policy, in advance, to detect, respond, and recover from cyber-attacks. The layer features a broad spectrum that combines procedures, people, and technology to ensure an effective response to threat sources caused by hackers, employees, vendors, customers, and contractors.
Implementing the Best Grade D-I-D for Your Organization
A study revealed that businesses and information technology security professionals spend tremendous resources, time, and money to develop and maintain defense-in-depth as part of their cybersecurity strategy. Regardless, cybercriminals still manage to carry out attacks on such systems and networks, indicating that the enemy is ahead of security teams, or the implementation of the strategy is untenable.
For small and medium enterprises, the dynamic security landscape that requires multi-faceted protection strategy poses a challenge considering that they run on small cybersecurity budgets and lack the appropriate skills needed to defend their systems and information. At the same time, building this castle-like defense mechanism involves integrating multiple security solutions and vendors. Businesses also need to work with experts to ensure proper configurations of security tools on the functionally different layers.
Ultimately, SMEs require clear visibility and automation to achieve defense-in-depth goals. They need to define, prioritize their security requirements, and select relevant security products and vendors to help implement their cybersecurity strategies.
