By Amy Larsen DeCarlo Hackers naturally gravitate toward the most vulnerable points on an enterprise to breach. The network, which by its nature requires a degree of openness to allow traffic to traverse it, is one of most attractive targets, with ample hardware vulnerabilities to

The key is incorporating them into a regular maintenance cycle. By By Teren Bryson Enterprise-grade network testing is one of the most frequently overlooked aspects of network engineering. Network engineers often spend so much time designing and architecting the network that we seldom think
Reading Time-approximately: 2 minutesA man-in-the-middle (MiTM) attack is one in which the attacker secretly intercepts and relays messages between two parties who believe they are communicating directly with each other. The attack is a type of eavesdropping in which the entire conversation is controlled by the attacker. Courtesy Post By TechTarget Contributor Sometimes referred to as a session hijacking attack, MiTM has a strong chance
Reading Time-approximately: 6 minutesA zero-trust model is a security framework that fortifies the enterprise by removing implicit trust and enforcing strict user and device authentication throughout the network. BySandra Gittlen and Laura Fitzgibbons This guide goes in-depth into the origins of zero trust, its architecture, the technology and products that comprise a zero-trust model, as well as how to implement and manage zero
Reading Time-approximately: 3 minutesAs more employees work remotely and VPN use rises, VPN concentrators have become trendy. But what does a VPN concentrator do exactly, and how do you deploy one? By Terry Slattery Virtual private networks are encrypted tunnels that protect network communications from unauthorized access when the communications must cross untrusted networks, like the internet. VPN concentrators are one component that
Reading Time-approximately: 3 minutesA remote access VPN connects remote users from any location to a corporate network. A site-to-site VPN, meanwhile, connects individual networks to each other. By Paul Kirvan and Lisa Phifer Remote working has become pervasive in business processes. While remote work, or teleworking, has been around for years — and the technology has become largely standardized — its importance to
Reading Time-approximately: 2 minutesWhile network security focuses on solely protecting networks, cloud security provides protection for networks, servers, containers, apps and more. By Andrew Froehlich Cloud computing has been around for a while, but confusion still surrounds the correct meaning of certain terms. An example of this is differentiating between cloud security vs. network security. First, let’s look at the term network security to understand
Reading Time-approximately: 4 minutesSome experts believe VPNs have struggled to adapt to an increasingly cloud-based, internet-dependent world. Enter zero-trust network access, which may be network security’s future. By Lee Doyle, Doyle Research In organizations with remote employees, productivity depends on secure, reliable access to applications, services and data over the internet from any device at any location or time. Yet, the internet can expose

By John Cavanaugh Distributed denial-of-service, or DDoS, attacks are becoming more common in enterprise networks and are sometimes even combined with ransomware. The main types of DDoS attacks are the following: Volumetric DDoS. This attack crushes devices
Reading Time-approximately: 3 minutesThe types of DDoS attacks organizations face have grown and size of these attacks has increased. Expert Michael Cobb explains how to secure systems against common DDoS methods. By Michael Cobb A distributed denial-of-service (DDoS) attack aims to exhaust the resources of a network, application or service so that genuine users cannot gain access. There are different types of DDoS
What is COVID-19?
On 31 December 2019, the World Health Organization (WHO) reported a cluster of pneumonia cases in Wuhan City, China. ‘Severe Acute Respiratory Syndrome Coronavirus 2’ (SARS-CoV-2) was confirmed as the causative agent of what we now know as ‘Coronavirus Disease 2019’ (COVID-19). Since then, the virus has spread to more than 100 countries, including South Africa.
