Cisco said today it had closed the $2.35 billion deal it made for network identity, authentication security company Duo.According to Cisco, Duo’s zero trust security model authorizes secure connections to all applications based on the trustworthiness of users and devices. Duo’s cloud-delivered technology lets IT professionals set and enforce risk-based, adaptive access policies and get enhanced visibility into users’ devices and activities. As more devices come onto the network remotely this issue takes on more importance.“Outdated devices are particularly vulnerable to being compromised, which can easily spiral into a full-blown, major breach,” wrote Richard Archdeacon, Duo Advisory CISO about a recent Duo study on remote access security. “Organizations don’t necessarily need to block individuals from using their personal devices, but they do need to re-shape their security models to fit these evolving working practices…If you don’t know what’s connecting to the network, how can you protect data from being compromised? “To read this article in full, please click here READ MORE HERE…

IDG Contributor Network: Security serves as an essential component to growing an enterprise with SD-WAN

As enterprises endeavor to expand domestic and global footprints, agile network infrastructure connectivity across geographies continues to prove an ongoing challenge. In particular, ensuring that data shared over these networks is protected from unauthorized access is a primary directive in today’s evolving cyber threat landscape. These often-contradictory demands call for IT decision makers to invest in innovation that will facilitate network flexibility and agility without compromising security, productivity or performance.This challenge begs a simple question. How can a WAN deliver the flexibility and agility necessary to help an organization grow without increasing exposure to data breaches and other security problems? After all, if the cost of convenience is increased network vulnerabilities, can it be considered a sound approach?To read this article in full, please click here READ MORE HERE…

What is Nmap? Why you need this network mapper

Network administrators, IT managers and security professionals face a never-ending battle, constantly checking on what exactly is running on their networks and the vulnerabilities that lurk within. While there is a wealth of monitoring utilities available for network mapping and security auditing, nothing beats Nmap’s combination of versatility and usability, making it the widely acknowledged de facto standard.What is Nmap?
Nmap, short for Network Mapper, is a free, open-source tool for vulnerability scanning and network discovery. Network administrators use Nmap to identify what devices are running on their systems, discovering hosts that are available and the services they offer, finding open ports and detecting security risks.To read this article in full, please click here READ MORE HERE…

How to protect your infrastructure from DNS cache poisoning

Domain Name System (DNS) is our root of trust and is one of the most critical components of the internet. It is a mission-critical service because if it goes down, a business’s web presence goes down.DNS is a virtual database of names and numbers. It serves as the backbone for other services critical to organizations. This includes email, internet site access, voice over internet protocol (VoIP), and the management of files.You hope that when you type a domain name that you are really going where you are supposed to go. DNS vulnerabilities do not get much attention until an actual attack occurs and makes the news. For example, in April 2018, public DNS servers that managed the domain for Myetherwallet were hijacked and customers were redirected to a phishing site. Many users reported losing funds out of their account, and this brought a lot of public attention to DNS vulnerabilities.To read this article in full, please click here READ MORE HERE…

The rise of next-generation network packet brokers

Network packet brokers (NPB) have played a key role in helping organizations manage their management and security tools. The tool space has exploded, and there is literally a tool for almost everything. Cybersecurity, probes, network performance management, forensics, application performance, and other tools have become highly specialized, causing companies to experience something called “tool sprawl” where connecting a large number of tools into the infrastructure creates a big complex mesh of connections.Ideally, every tool would receive information from every network device, enabling it to have a complete view of what’s happening, who is accessing what, where they are coming in from, and when events occurred.To read this article in full, please click here READ MORE HERE…

What are the options for securing SD-WAN?

A key component of SD-WAN is its ability to secure unreliable Internet links and identify anomalous traffic flows.SD-WAN technology providers are continuing to increase their native security features and to create robust ecosystems of network-security partners.[ See where SDN is going and learn the difference between SDN and NFV. | Get regularly scheduled insights by signing up for Network World newsletters. ]

SDNs and NFV are complementary and core components of modernized networks

The terms software defined networking (SDN) and network functions virtualization (NFV) are often used interchangeably, which is incorrect. In a sense, the two are tied together as companies start using NFV as part of their SDN plans but that doesn’t have to be the case.Enterprises could maintain their current network architecture and shift to NFV or they could roll out an SDN and never leverage the benefits of NFV, so it’s important to understand what each is and the benefits of both.[ For more on SDN see where SDN is going and learn the difference between SDN and NFV. | Get regularly scheduled insights by signing up for Network World newsletters. ]
What is software-defined Networking
SDNs are a fundamentally different way to think about networks. Technically, SDNs can be defined as the separation of the management, control and data-forwarding planes of networks. Many people, including technical individuals read that definition and say, “So what?”, but the separation of these planes has a profound impact on networks and enables things that have never been done before.To read this article in full, please click here READ MORE HERE…
