Did you know that the zero trust security model is going to be more important than ever in 2022? Here’s a guide to what you need to know about it and how to make sure your company is compliant.
Zero Trust Security
The organizational cybersecurity approach is based on the assumption that any trusted zone is an attack surface. The Zero Trust Security model aspires to eliminate the trust boundary between the trusted internal network and the untrusted external network. Exploring the principles and benefits of the ZTNA architecture.
The data-driven cybersecurity approach focuses on protecting high-value assets from cyber-attacks in real-time. It is based on big data analytics and machine learning. ZTNA principles apply to outsourcing cybersecurity services.
Zero Trust Security Control Framework
The Zero Trust Network Architecture (ZTNA) is agnostic to compliance and risk management frameworks. It applies to any type of compliance including PCI, SOC2, SOX, HIPAA, and others. Cybersecurity controls are built into the fabric of the ZTNA model.
The article provides an overview of the ZTNA control framework and its benefits. ZTNA is based on key principles. First, to remove the trust boundary between the internal network and the untrusted external network. Second, to assume that any trusted zone is an attack surface.
Moreover, all devices should be treated as hostile. Third, to assume that all communication channels can eavesdrop.
Centralized Management
This concept works well with centralized management solutions. The ZTNA model puts an end to the era of network perimeter security. So, it replaces it with an approach that assumes all devices are untrustworthy and all communication channels can eavesdrop.
The need for centralized management solutions has been growing in recent years. This is due to the growing complexity and number of security tools deployed in enterprise networks. This article discusses some common centralized management solutions.
These techniques are Cisco Prime, and Microsoft System Center Configuration Manager (SCCM). It also includes Juniper Networks Junos Space, McAfee ePolicy Orchestrator (ePO), HP OpenView Secure Web Gateway (SWG), and others.
The zero-trust network architecture (ZTNA) has been gaining momentum recently among network security architects. ZTNA is based on two fundamental assumptions: (1) any trusted zone is an attack surface, and (2) every device is untrusted.
Zero Trust Security Is Not a Panacea
The approach focuses on real-time situational awareness. This uses big data analytics and machine learning techniques to detect unusual patterns of behavior in real-time. But without making false positives or false negatives.
Then taking action based on risk thresholds set by security analysts within specified SLA (Service Level Agreement). ZTSA solutions provide continuous monitoring of critical assets in real-time with near-zero tolerance for false positives or false negatives. Then take appropriate action based on risk thresholds set by security analysts within specified SLA goals.
Thus, providing continuous and uninterrupted service availability for critical business applications. This is with high assurance levels of security effectiveness. Also, it includes proactive detection and prevention of advanced persistent threats (APTs).
