As you saw in a previous post, DHCP Hacking Made Easy, poorly configured networks can serve as an attack vector for “The Attacker”. In this entry, we continue this exploration with another dead simple attack on the network, ARP spoofing. ARP is the protocol responsible for informing hosts within a given LAN, which IP addresses belong to which MAC addresses. What happens when we provide bad...

Poorly configured networks are vulnerable to many attacks. Easy attacks. In this blog we will demonstrate how easy it is to perform a DoS attack on a DHCP scope. Afterwards, we will remediate our poorly configured network devices with a security feature that you should include on every deployment to protect against this type of attack.

Today we are talking about 802.1X, like authenticating a device coming into a conference room.What is 802.1X ? In simple terms, it is an authentication mechanism that we leverage.

Today kicked off day one of Cisco Live 2018 in Orlando, FL! The day was filled with a keynote, breakout sessions, Innovation Showcases, and of course the World of Solutions. Here are our top takeaways from Cisco Live Day 1.

You have been working as a network administrator for your company for a few years now. In that time you have been asked to complete a handful of network projects; a new office turn up here, replace some switches or a router there. The whole time you work from old templates or, in the case of replacement gear, just copy and paste the old config. Have you ever really stepped back and looked at the...

Many refer to the digital revolution as the industrial revolution of the 21st century. Technology has become fundamentally integrated to all aspects of our society as it impacts all aspects of business and society today. The network is the foundation from which we have built our digital lives. As a business, you rely on your network to function securely and expediently, and in the age of digital...

Today more and more businesses are focused on application security and visibility. With expected exponential growth in online devices - from 15B today to an expected 500B by 2030, securing those devices has never been more important. Today’s rapidly evolving business models reflect trends like hybrid cloud, mobility and BYOD, meaning the traditional network perimeter has largely dissolved. The...

Network security is often delegated to singular devices within the network. For instance, you might allow unfettered access for all endpoints within the core of your corporate network and enforce the access policy at the edge firewall. For your wireless users, you might choose to enforce a singular policy for all users allowing every wireless user access to HTTP, HTTPS, SSH, and Telnet and...

Collaboration solutions for the modern workforce are focused more and more on enabling the mobile workforce, and why should security be any different? Today’s workforce is digitizing rapidly with more and more companies’ business model reflecting trends like mobility and “bring your own device”. The exponential growth of online devices is expected to grow from 15B today to 500B by 2030. With...
