Microsegmentation is a network security approach that allows engineers to logically partition data centers into discrete security segments—right down to the level of each task—and apply security policies to each segment separately. Rather than establishing numerous physical firewalls, microsegmentation allows IT to set flexible security policies deep inside a data center. With microsegmentation, you can secure every virtual instance or virtual machine (VM), bare-metal server,...

The RADIUS (Remote Authentication Dial-In Service) protocol is a client-server networking protocol that facilitates communication between a central server and individual users who want to gain access to the server.  Essentially, RADIUS allows remote access servers to communicate with the central server to authenticate and authorize remote user access. With RADIUS, companies can store user profiles in a central database that can be shared across...

VMware NSX is a network virtualization and security technology that supports VMware's cloud networking solution. It provides a software-defined networking strategy that spans data centers, clouds, and application frameworks.  NSX brings networking and security closer to the application, regardless of where it runs, from virtual machines (VMs) to containers to physical servers. Networks, like VMs, may be deployed and operated regardless of the underlying hardware. VMware...

Whether it's a small business, or enterprise office, mesh networking can extend wireless coverage while improving Wi-Fi performance and enabling administration for local internet access. Administrators can install and configure a network with hubs strategically placed to maximize a network's physical reach through a specialized mesh router. Without running cords across office space, mesh Wi-Fi networks use satellite nodes to increase connectivity and speed and...

Network-attached storage (NAS) hardware and software solutions can ease and enhance the task of managing data for individuals up to enterprise data centers. NAS appliances offer organizations secure storage and file access to groups of users at a lower cost relative to the latest file servers. Both file servers and NAS perform similar functions, but most organizations don’t need the extent of features included in...

The speed of processing power and server responses in modern IT infrastructure is due to the widespread adoption of load balancers capable of distributing workloads between multiple servers. Today, load balancing systems go beyond hardware, extending to software, cloud-based, and virtual appliances. Their newest iteration, application delivery controllers (ADC), offer critical capabilities for redirecting and routing traffic, protecting against web application attacks, and accelerating service...

Since the internet's earliest days, public-facing organizations have established security systems to defend sensitive data from external forces that seek to compromise it. One tried-and-true method is the creation of sub-networks between untrusted WANs and an organization's internal resources, dubbed demilitarized zones (DMZ).  Though DMZ networks still offer a buffer between untrusted users and internal segments, the adoption of cloud services and virtualization means the...

Finding the best server management software tools for your organization can have a major impact on the success of your business operations. Manually handling all tasks associated with server management and critical applications is time-consuming and costly. However, these tasks must be completed to ensure the health of your network.  This becomes even more complex and tedious when you expand your infrastructure by adding multiple...
