Systems architect12/24/2023 The Need For System-Level Security And Persistent Data Protection They didn’t do this until after the attack, and so their security was compromised with severe and far-reaching effects. They then could have leveraged a standards-based, incremental process to monitor, check and protect those endpoints. Had they conducted an inventory of IoT assets, they would have understood the critical gaps that were traversed in the attack. They should have inventoried their systems long before they were hit. Organizations must continually monitor and evaluate their architecture, identifying, prioritizing and addressing potential threats in real time.Īs a case in point, one company I observed fell victim to a widely publicized ransomware attack. Continuous Monitoring And Evaluation: The initial assessment is just a starting point.If informed by the prioritization of critical assets and applications, those areas can be micro-segmented first. Incremental Micro-Segmentation: Micro-segmentation, a core principle of ZTNA, which I discussed in my last article, involves dividing the network into smaller segments to isolate potential threats and limit lateral movement within the network.Leveraging Existing Security Tools: To minimize costs and streamline the implementation process, organizations should leverage their existing security tools, such as firewalls and intrusion detection systems, to support the transition to ZTNA. Prioritizing Critical Assets And Applications: Organizations should prioritize the protection of their most critical assets, incorporating ZTNA principles into these areas before moving on to less sensitive systems.This provides the basis of a roadmap for incrementally integrating ZTNA principles into the existing system. Comprehensive Assessment: Organizations should first assess their current security infrastructure, identifying potential vulnerabilities and areas for improvement.Furthermore, it ensures that legacy and low-computing IoT devices-often overlooked by traditional cybersecurity approaches-are secured, paving the way for a more robust architecture.Ī standards-based approach to incremental ZTNA adoption starts with: By adopting ZTNA incrementally, organizations can gradually enhance their security infrastructure without sacrificing functionality or incurring excessive costs.
