Use zero trust to fight network technical debt

Zero trust (ZT) is a mindset and a method, not a technology. The current push to adopt ZT is driven by an urgent and growing need to make a major leap forward in risk management and attack containment in enterprise networks, a need driven home by every successive wave of ransomware. IT can use the urgency of moving to ZT to root out some of the technical debt in the environment. Specifically, it can be a catalyst to find areas exempted from network and network security standards and bring them up to date under the new paradigm of zero trust.No more exempting network components from access-control roles
In a ZT environment, the network not only doesn’t trust a node new to it, but it also doesn’t trust nodes that are already communicating across it. When a node is first seen by a ZT network, the network will require that the node go through some form of authentication and authorization check. Does it have a valid certificate to prove its identity? Is it allowed to be connected where it is based on that identity? Is it running valid software versions, defensive tools, etc.? It must clear that hurdle before being allowed to communicate across the network.To read this article in full, please click here READ MORE HERE…

IBM service aims to secure multicloud operations

IBM is launching a new service to help customers manage their data encryption keys in a hybrid cloud environment. Unified Key Orchestrator lets customers integrate all security key-management systems into one managed service that’s backed by Big Blue’s Hardware Security Module. HSM is IBM’s system that protects against physical or logical attacks and has special hardware to perform cryptographic operations and protect keys.Gartner: IT skills shortage hobbles cloud, edge, automation growth
Available from IBM Cloud, Unified Key Orchestrator lets customers maintain visibility and control over who has access to their critical data, while running workloads across hybrid or multicloud cloud environments. In addition, with a single, secure, cloud-based  view of an organization’s crypto keys, enterprises can create and revoke keys for their data across multiple clouds. At the same time, companies no longer need to rely on security experts with specialized knowledge of each individual cloud to handle security operations, according to IBM.To read this article in full, please click here READ MORE HERE…

What is NAC and why is it important for network security?

Network Access Control (NAC) is a cybersecurity technique that prevents unauthorized users and devices from entering private networks and accessing sensitive resources. Also known as Network Admission Control, NAC first gained a foothold in the enterprise in the mid-to-late 2000s as a way to manage endpoints through basic scan-and-block techniques.As knowledge workers became increasingly mobile, and as BYOD initiatives spread across organizations, NAC solutions evolved to not only authenticate users, but also to manage endpoints and enforce policies.How NAC works
NAC tools detect all devices on the network and provide visibility into those devices. NAC software prevents unauthorized users from entering the network and enforces policies on endpoints to ensure devices comply with network security policies. NAC solutions will, for instance, make sure that the endpoint has up-to-date antivirus and anti-malware protections.To read this article in full, please click here READ MORE HERE…
