Understanding Multi-Layered Security: An Essential Piece of Today’s Cybersecurity Puzzle
As experienced, executive-level leaders, understanding and investing in cybersecurity is more crucial than ever. One term that stands at the forefront of this domain is Multi-Layered Security. But what exactly does this mean, and why is it so critical in our digital era?
1. Definition: Simplifying Multi-Layered Security
Multi-Layered Security, also referred to as defense in depth, is a comprehensive approach to cybersecurity that uses multiple lines of defense to repel potential cyber-attacks. Instead of relying on a single security measure, it uses a series of different types of security controls across various points in an information system.
2. History: Unraveling the Roots of Multi-Layered Security
The concept of Multi-Layered Security is not a new phenomenon. In fact, it can trace its roots back to military strategies used in ancient and medieval times. The Castle approach to defense – using high walls, moats, drawbridges, and soldiers – is an apt analogy to depict this strategy. Like the castle, if one layer is breached, the attackers still find several more layers to conquer. This approach is now a cornerstone of modern-day cybersecurity best practices, allowing organizations to combat the constantly evolving tactics of cybercriminals significantly.
3. Examples: The Real-World Impact of Multi-Layered Security
- The 2017 Equifax data breach, which exposed the sensitive information of 147 million consumers, could have been prevented by applying Multi-Layered Security. After the incident, Equifax confessed that a single layer of security failed and led to the breach.
- The WannaCry ransomware attack in 2017 affected hundreds of thousands of computers worldwide. The organizations that managed to evade this attack had Multi-Layered Security measures in place that were able to identify and put a halt to the ransomware.
4. Insight: Mitigating Risks Associated with Cyber Threats
A key tip for implementing a Multi-Layered Security approach is incorporating a combination of preventive, detective, and corrective controls. Preventive controls like firewalls and antivirus software deter hackers, detective controls like intrusion detection systems catch unauthorized activities, and corrective controls help restore systems post-attack. A holistic mix of these is your best bet against potential cyber threats.
