Cybersecurity has evolved rapidly, and the Zero Trust philosophy has become crucial for protecting users and corporate networks.
With the proliferation of remote work and the way applications are currently accessed, along with the distribution of infrastructures between on-premises and public clouds, the challenge of keeping these accesses secure without affecting user experience and productivity increases significantly.
But what exactly does "Zero Trust" mean, and how is this approach, combined with Zero Trust Network Access (ZTNA) and Secure Access Service Edge (SASE), shaping corporate security? In this article, we will explore these concepts and understand their combined importance in cybersecurity.
What is Zero Trust?
Zero Trust is a security philosophy based on the principle that no entity, whether internal or external to the network, should be implicitly trusted. Instead, continuous identity and context verification is essential for all accesses and activities on the network.
Zero Trust Network Access (ZTNA)
ZTNA is the practical application of the Zero Trust philosophy in network access. Unlike traditional VPNs, which grant broad network access, ZTNA allows granular access based on user identity and context. Key features include:
Identity-Based Access: Access is granted based on user and device identity rather than location.
Minimum Privileges: Only the necessary level of access to perform a specific task is granted.
Continuous Evaluation: The security state of the device and user is continuously evaluated to ensure dynamic application of security policies.
Microsegmentation: Aims to reduce the attack surface and lateral movement by limiting access to only necessary resources and dividing the network into smaller segments.
Secure Access Service Edge (SASE)
SASE is a framework that combines networking and security capabilities into a single cloud-based solution. Developed to support the Zero Trust philosophy, SASE integrates functions such as ZTNA, Firewall-as-a-Service (FWaaS), SD-WAN, Cloud Access Service Broker (CASB), Secure Web Gateways (SWG), and VPN-as-a-Service (VPNaaS). This integration of network and security services, fully delivered in the cloud, ensures scalability and flexibility.
The importance of combining ZTNA and SASE
The combined use of ZTNA and SASE is fundamental for corporate security in 2024, providing comprehensive protection and a holistic approach to security, including secure access to on-premises private networks, application and device protection, and access to cloud resources, SaaS, and websites. It ensures quick and seamless access, offering a better user experience while reducing management complexity with an integrated platform.
