June 3, 2022 TH Author access control, akamai, Cisco systems, Citrix Systems, Network Security, remote access, Security

Enterprise interest in Zero Trust Network Access (ZTNA) has soared over the past two years among organizations trying to enable secure anywhere, anytime, any device access to IT resources for employees, contractors and third parties.Much of this interest has stemmed from organizations looking to replace VPNs as the primary remote access mechanism to their networks and data. But it is also being driven by organizations seeking to bolster security in an environment where enterprise data is scattered across on-premises and multi-cloud environments, and being accessed in more ways than ever before.To read this article in full, please click here READ MORE HERE…

Arriving at a consensus on when 6G wireless will be widely available commercially is all but impossible, as this small sample size shows:
Northeastern University researchers: More than five years, but probably not long after
Nokia CEO Pekka Lundmark: Definitely by 2030
ABI Research: Sometime in the 2030s

SASE or SSE? Don’t let hype distract from enterprise needs

May 23, 2022 TH Author Network Security, SD-WAN

Secure access service edge (SASE) has generated a buzz over the last couple of years, particularly in light of the pandemic and its associated surge in remote employees. But SASE hasn’t quite materialized in the way Gartner – which first coined the term in a 2019 white paper – initially expected. In particular, there’s been pushback around the idea that SASE should be delivered by a single vendor, as a single integrated cloud service at the network edge.The SASE model combines network security functions with WAN capabilities, delivering the security elements in the cloud and using SD-WAN at the edge or in the cloud. Key security functions include secure web gateway (SWG), zero trust network access (ZTNA), firewall as a service (FWaaS), and cloud access security broker (CASB).To read this article in full, please click here READ MORE HERE…

6 top network security threats and how to beat them

May 11, 2022 TH Author Network Security

It’s a war zone out there. In the seemingly endless game of cyber cat and mouse, accurate intelligence remains the best tool for beating attackers at their own game.Here’s an analysis of today’s six top network threats and tips for how to identify and quash them.1. Ransomware
Ransomware is easily the greatest network threat, since it gives attackers the biggest bang for the buck with a relatively low probability of getting caught. “There’s also a low bar in the skill category to break into this sort of thing,” says Andy Rogers, a senior assessor at cybersecurity and compliance firm Schellman. “There are plenty of Ransomware-as-a-Service (RaaS) businesses that will be more than willing to ensure you have the tools you need to unleash a ransomware campaign.”To read this article in full, please click here READ MORE HERE…

Cisco warns of critical vulnerability in virtualized network software

May 5, 2022 TH Author Network Security, Security, virtualization

Multiple vulnerabilities have been discovered in Cisco’s Enterprise NFV Infrastructure Software (NFVIS). The worst of the vulnerabilities could let an attacker escape from the guest virtual machine (VM) to the host machine, Cisco disclosed. The other two problems involve letting a bad actor inject commands that execute at the root level and allowing a remote attacker to leak system data from the host to the VM.NFVIS is Linux-based infrastructure software designed to help enterprises and service providers to deploy virtualized network functions, such as a virtual router, firewall and WAN acceleration, Cisco stated.To read this article in full, please click here READ MORE HERE…
