How Zero Trust Security Protects Modern Businesses

In the past, there was a reliance on the castle-and-moat model. Companies would construct very secure fortifications around their networks and then believe anything on their side of the corporate perimeter is safe. 

In today’s environment with remote working, cloud migration, and advanced cyberattacks, that security boundary has been obliterated. If someone breaks through the outer perimeter, they gain unfettered lateral movement across the entire network. 

This is why organizations are switching to a zero trust strategy, a flexible defensive framework that operates under one simple principle: never trust, always verify.

Basic Concept of Zero Trust Security Architecture

One can envision the zero trust security architecture concept as a highly secured facility where a keycard will be necessary for access through each inner door, not just the entrance doors.

In a zero-trust system, there is no trust associated with any computer’s position on the network or even its geographical location. Instead, all connections must go through rigorous validation of identity and authorization.

Key Components for Continuous Protection

The successful deployment of such a new system is based on three key components:

• Explicit Validation: All of the data is evaluated by the system before granting any access permissions, including the identity of the person, their geographical location, the state of the hardware, and the context of the request itself.
• Least Privilege Access Principle: Both people and applications get only the minimum permissions to do their job.
• Assume Breach Approach: Security specialists design their network based on the assumption that hackers are already present in the network and use micro-segmentation to limit their movement.

Key Advantages for Developing Businesses

Employing zero trust security provides essential security advantages in today’s modern and dispersed workplace environments:

• Protection of Remote and Hybrid Workforce

  Employees can access the organization’s database and cloud services from any personal device and anywhere without putting the core infrastructure at risk of cybersecurity.

• Prevention of Lateral Movement of Cyber Attacker

  In case a cyber attacker manages to get to one compromised device, segmented access prevents them from deploying ransomware in the remaining part of the corporate network.

• Streamlined Regulatory Compliance

  Ongoing verification and audits of identity will help businesses to meet data protection standards in the financial, healthcare, and cloud industries.

Conclusion

While corporate networks continue expanding far beyond the physical boundaries of offices, the use of out-of-date methods of perimeter security puts corporate assets at risk. Utilizing zero trust security gives a secure and proactive approach to protect the company’s resources in a cloud-first world.
