It was about 20 years ago when I plugged my first Ethernet cable into a switch. It was for our new chief executive officer. Little did she know that she was about to share her traffic with most others on the first floor. At that time being a network engineer, I had five floors to be looked after.Having a few virtual LANs (VLANs) per floor was a common design practice in those traditional days. Essentially, a couple of broadcast domains per floor were deemed OK. With the VLAN-based approach, we used to give access to different people on the same subnet. Even though people worked at different levels but if in the same subnet, they were all treated the same.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…

Automation critical to scalable network security

Securing the business network has been and continues to be one of the top initiatives for engineers. Suffering a breach can have catastrophic consequences to a business, including lawsuits, fines, and brand damage from which some companies never recover.To combat this, security professionals have deployed a number of security tools, including next-generation firewalls (NGFW) such as Cisco’s Firepower, which is one of the most widely deployed in the industry. Managing firewalls becomes increasingly difficult
Managing a product like Firepower has become increasingly difficult, though, because the speed at which changes need to be made has increased. Digital businesses operate at a pace never seen before in the business world, and the infrastructure teams need to keep up. If they can’t operate at this accelerated pace, the business will suffer. And firewall rules continue to grow in number and complexity, making it nearly impossible to update them manually.To read this article in full, please click here READ MORE HERE…

Cato Networks adds threat hunting to its Network as a Service

Enterprises that have grown comfortable with Software as a Service (SaaS), Infrastructure as a Service (IaaS) and Platform as a Service (IaaS) are increasingly accepting of Network as a Service (NaaS). NaaS is a rapidly growing market. According to Market Research Future, NaaS is expected to become a US $126 billion market by 2022, sustaining an annual growth rate of 28.4 percent.One of the key benefits of cloud-based networking is increased security for applications and data. Given that the traditional perimeter of on-premise networks has been decimated by mobile and cloud computing, NaaS builds a new perimeter in the cloud. Now it’s possible to unify all traffic – from data centers, branch locations, mobile users, and cloud platforms – in the cloud. This means an enterprise can set all its security policies in one place, and it can push traffic through cloud-based security functions such as next-generation firewall, secure web gateway, advanced threat protection, and so on.To read this article in full, please click here READ MORE HERE…
