To iPad or not to iPad, that is the question
Is there truly value to leveraging iPads and other mobile devices in healthcare? Or is it just an excuse for a Doctor to get a shiny toy?
When you only have two colors, all your pictures are black and white
How can an OEM or vendor be truly agnostic if they can only sell one product line?
Security Assessments (Part 1)
I'm very excited to contribute my first series of posts to the new GTRI Technology Blog!
Using Dual Protocol for SIEMs Evasion
It is just a fact of life that attackers and defenders are now operating in a dual-protocol world. With the addition of IPv6, attackers are learning new tricks and defenders will need to anticipate and protect against those new attacks.
Core Networking and Security 100th Blog Post
This is my 100th blog post for the Network World Cisco Subnet community. As I reflect on the last four years of writing this blog, I think about the fun I've had sharing ideas with you and hearing your feedback.
IPv6 Certifications
Many networking, systems and security engineers have been studying IPv6-related topics for many years. You may be wondering if you can get a certification to show for all the time and effort you have spent learning IPv6.
9 Common Spanning Tree Mistakes
Ethernet devices running the Spanning Tree Protocol (STP) have been implemented in networks since the early 1990s. Many organizations take STP for granted and do not configure it per industry best practices.
Time to Upgrade Cisco Catalyst 6500 Non-E-Series Chassis
The Cisco 6500 Ethernet switches were introduced in 1999 and have been deployed by more than 45,000 organizations.
U.S. Government Progress on IPv6 Deployment
The United States government has been striving to deploy IPv6 for many years. October 1st was the date that the government wanted to have functional IPv6-enabled Internet applications.
IPv6 Is Not an All-or-Nothing Proposition
I have recently met many people who are under the impression that an organization must transition directly from IPv4 to IPv6. Thankfully, this is not the case.
IPv6 NAT - You can get it, but you may not need or want it.
Dual stack is the most preferred IPv6 transition strategy and tunneling IPv6 packets within IPv4 packets is considered less optimal.
Achieving PCI Compliance When Using IPv6
The PCI DSS was written with IPv4 in mind and it requires that NAT be used to protect servers containing cardholder information.
RIPE NCC IPv4 Address Exhaustion
IPv4 address depletion is occurring around the world. Now, one more region of the world has all but extinguished its supply of IPv4 addresses.
Web Application Firewalls and IPv6
Many organizations may be using a Web Application Firewall (WAF) to help them achieve security compliance and secure their web applications.
Dual-Stack Will Increase Operating Expenses
As we start to plan for IPv6 and start to deploy it on our networks we should try to anticipate the operational costs related to running both IPv6 and IPv4.
Life After World IPv6 Launch
It has been several weeks since World IPv6 Launch took place on June 6th. However, it will remain the single biggest event in the development of IPv6 for many years.
Google IPv6 Implementors Conference
This week I was fortunate enough to attend the Google IPv6 Implementors Conference. This event was a gathering of the top technical experts working on furthering IPv6 deployment around the world.
Free IT Training – A Reality in 2009
If your company is like many others these days they may have cut the training budget. However, you owe it to yourself to take ownership of your own professional development.
Recycling – A Key Part of a Green IT Strategy
Just about everywhere you look these days you are sure to see companies looking to make the IT industry “Green”.
Security at 10Gbps
Many organizations are contemplating upgrading their core networks to 10Gbps links while some organizations have already implemented a 10Gbps core infrastructure.
Tagging the Native VLAN
In Cisco LAN switch environments the native VLAN is typically untagged on 802.1Q trunk ports. This can lead to a security vulnerability in your network environment.
Cisco Adds Features to Firewall Services Module
The Firewall Services Module (FWSM) in a Cisco 6500 switch has been the system of choice for those seeking to achieve over 5 Gbps of stateful firewall forwarding performance with over 100K connections/second and over 1 million active connections.
Spanning Tree - Oh Woe Is Me
I am amazed by the number of networks that I encounter that do not have optimal spanning tree configurations.
IPv6 Capabilities in Cisco’s IPS Software Version 6.2
I knew the topic of IPv6 Security was likely to see many changes in the years to come because it is such a dynamically evolving technology area.
Windows 7 IPv6 Support
The more some things change the more they same the same. That is certainly true for the IPv6 support in Windows 7.
Practical BGP Security
The vulnerabilities in the Border Gateway Protocol (BGP) have been widely known for many years now.
Cisco IPv6 Support Comes Standard
I wanted to share with you something that I have observed in the recent release notes for some of the newest Cisco IOS versions.
Configuration Management on a Budget
When most people think about configuration management solutions it often conjures up images of very expensive enterprise-class software packages. These software packages can be large and cumbersome and may be overkill for most organizations who want to achieve some of the same results on a tighter budget.
IPv6 on Your Mobile Phone
You may have IPv6 capabilities on your mobile phone and not even realize it. It has become apparent in 2008 that several mobile phone providers in the U.S. have started to include IPv6 capabilities in their phones.
Increasing Network Availability with Visio
Today, most business applications are network centric. Their real-time business applications require the highest level of network availability.
I Want IPv6 for Christmas
There are several things that I want for Christmas. Here is my abbreviated Christmas list:
