Zero-trust environments can protect sensitive data from attackers. By implementing policies to prevent security risks before they become serious, zero-trust environments can ensure that a user’s information is secure and prevent unauthorized access. This approach can help ensure that users’ privacy is protected and also help organizations avoid unnecessary costs.
Segmenting Infrastructure
Micro-segmenting networks allow for specific policies and controls on network access. This micro-segmentation provides network security by allowing users to access only the bare minimum of network resources. It also enables control over lateral movement in a network.
A Zero Trust model requires strict policies on user authentication, access control, and identity management. As such, it requires sophisticated architecture. There are many potential Zero Trust solutions available in the market. This article looks at one solution that can simplify building your network infrastructure.
Micro-segmenting networks help organizations reduce the risk of cyber attacks by limiting the amount of network traffic that can reach sensitive systems. This type of security also supports multi-cloud environments and bare-metal servers. In addition, these network segmentation solutions provide granular policy controls, which can help prevent lateral threats to data centers.
In addition to micro-segmenting networks, Zero Trust networking solutions can also help organizations implement a continuous monitoring strategy to identify and mitigate threats. With continuous monitoring, companies can also minimize the risk of malware and malicious code entering their networks. Aruba ESP enables Zero Trust best practices and provides a complete set of capabilities that address network security challenges. This solution provides visibility, control, and security to meet the needs of a distributed, IoT-driven network infrastructure.
Zero Trust network access is a new approach to secure networking. It replaces VPNs with micro-segmentation. It only allows authorized users to access the network after authentication and verification. It also prevents lateral movement within the network, significantly reducing the potential attack surface and security risk.
Implementing a Zero-Trust Network Access Model
Implementing a zero-trust network access security model for your business requires several essential steps. First, the policy engine must understand what users and subjects are accessing on the network. For example, a legacy system often gives users blanket access to all resources, so it is critical to limit this in a zero-trust architecture. Moreover, it should apply audit actions and logs to validate access.
Zero Trust also limits the attack surface, which reduces the amount of damage caused by a breach. Zero Trust models apply to the inside and outside perimeter of the network. In addition, they combine filtering, analytics, and logging to monitor activity and signals of compromise continuously.
Implementing a zero-trust network access security model is a difficult task and requires buy-in from key stakeholders. Most organizations struggle with change, and political issues can complicate the process. While you can integrate your existing infrastructure into the Zero Trust approach, most networks will need to introduce additional processes and capabilities.
Zero-trust network access policies are highly adaptive and constantly reassess user privileges based on context. This helps eliminate the attack surface, eliminates the risk of lateral movement, and reduces the likelihood of a compromised device infecting other resources. Zero-trust networks can also be easier to manage than traditional networks.
Benefits of Micro-Segmentation
Microsegmentation is a form of zero-trust network access management that gives you fine-grained control over who can access data and resources. It consists of three key elements: pinpointed security controls, fine-grained access policies, and access management identities.
Microsegmentation works by partitioning the network into smaller zones and tying security policies to individual application workloads. This reduces the attack surface and limits bad actors from moving laterally within the network. This valuable security feature will help you protect your business from cybercrime.
Microsegmentation allows you to create perimeters around sensitive data, separating regulated data from non-regulated data. This gives you superior visibility and control, especially during data breaches and audits. Moreover, micro-segmentation allows you to restrict connections between your development and production environments granularly.
Microsegmentation is also an effective method for meeting compliance requirements. Microsegmentation uses virtualized network switches or hypervisor backplanes to integrate with your infrastructure and dynamically apply security policies. It allows administrators to set affinity policies for various types of traffic and block threats as they move laterally. This is especially effective for protecting your data in cloud environments.
Microsegmentation reduces the attack surface by reducing the data that can move laterally. It also improves your ability to detect breaches and prevent lateral movement. It also helps you strengthen your regulatory compliance posture by limiting the lateral movement of attackers. With micro-segmentation, you can implement uniform security policies across hybrid environments. This can also help you manage incident response and provide telemetry on policy violations.
