Understanding Zero Trust Security
Zero Trust Security is a contemporary cybersecurity approach that assumes no trust by default and necessitates stringent identity verification for each user and device accessing resources. This approach, also known as the Zero Trust Security model, seeks to eliminate the traditional network perimeter and instead focuses on verifying the identity of users and devices. “Never trust, always verify” exemplifies the core concept of Zero Trust. This philosophy ensures that all users, applications, and devices are treated with suspicion and verified each time they request access to resources. This principle is closely related to access management, as it requires strict control over who can access resources, thus minimizing the attack surface.
The main technology associated with Zero Trust architecture is Zero Trust Network Access (ZTNA). ZTNA establishes trust through context and has been implemented across 150 data centers worldwide. By shifting from traditional perimeter-based security to Zero Trust, organizations can address the challenge of increased complexity in security, offering enhanced security and reduced attack surface, improved security for remote work, and simplified regulatory compliance.
The Shift from Perimeter-Based Security
The move from traditional perimeter-based security to Zero Trust Security is centered on user identity, device health, and context as opposed to location. This means that access requests are evaluated based on these factors, rather than simply relying on the user’s location within the network. Traditional network security utilizes authorized IP addresses, ports, and protocols to implement access controls and affirm what is trusted within the network. In contrast, Zero Trust Security considers all traffic, even if it is already within the perimeter, as untrustworthy.
By emphasizing user identity, device health, and context, Zero Trust Security offers an extra layer of protection against cyber threats. For instance, even if a malicious actor gains access to the corporate network, they would still need to bypass the Zero Trust access controls to access sensitive data and applications. This shift from relying on network boundaries to focusing on user and device authentication significantly reduces the attack surface and strengthens overall security posture.
Core Principles of Zero Trust Security
The core principles of Zero Trust Security include continuous verification, least-privilege access, and microsegmentation. Continuous verification refers to the process of requiring users and devices to be periodically re-verified by timing out logins and connections once established. This constant re-authentication ensures that even if a malicious actor gains access to a user’s credentials, their access will be limited and short-lived.
Least-privilege access and microsegmentation are both aimed at minimizing lateral movement within the network. Least-privilege access ensures that users and devices are granted access to only the resources necessary for completing their tasks. Microsegmentation, on the other hand, involves dividing the network into smaller, isolated segments to protect confidential systems and data. Both these principles work together to create a more secure environment by preventing potential threats from spreading across the enterprise.
