As summer rolls into fall, my kids are heading back to school. It’s always an interesting transition but this year even more so with my daughter going away to college for the first time. This has brought back a flood of memories from my own college education experiences.
I have always had a passion for education and have a strong belief in continous learning.
Today, so much is available on the web, through social media websites, and online video.
In the world of technology and government, there is so much more to learn every day. New technologies: cloud, cybersecurity and virtualization, new delivery methods: virtual classrooms, online video, and collaboration, and new government requirements and certifications.
Today, more than ever, an increasing number of Cisco employees and its extended workforce are connecting to Cisco’s corporate network using their devices of choice. The speed by which these devices are joining the network is not only staggering, but also significantly impacting the IT and security organizations’ approach to protecting the information assets and the services we deliver. The Apple iPad, as a prime example, actually appeared on the Cisco network the day before the technology was released to the general public, showing that IT and security professionals need to be aware, prepared, and nimble enough to keep pace with the speed of today’s innovation and change.
Most large organizations and enterprises at least try to take security pretty seriously. This means that the front door is not only usually locked, it is fortified and reinforced. This makes it hard for the bad guys to get in. So, do they give up? Of course not! What they do instead is look around back and start rattling the door knobs on the shed and cellar and the servants entrance and try to work their way in that way.
High value targets are usually locked down and secured pretty well, but this is not always the case for lower value targets. Once compromised, these lower value targets can provide a useful platform from which to attack other systems. For example, while traffic from the internet to internal hosts may be tightly limited, in many cases traffic between machines in the DMZ may not be as well regulated. Thus if you can own one machine in the DMZ, it can be easier to compromise other systems.
A collaboration of four senior members of the Cisco IPS signature team recently culminated in the public release of a guide on writing custom signatures for Cisco IPS, the #1 IPS platform of the Internet. The idea behind this move is to give our customers an easier way to develop their own signatures, allowing them to more easily discover and block unwanted traffic in their networks. At the same time it helps in understanding existing signatures written by members of the IPS signature team.
You can protect your small business wireless network from intruders with a few simple tweaks
A wireless network makes sense for small businesses. It enables you to connect wired and wireless devices, allowing you to expand your network operations and keep employees productive. Also, a wireless LAN (WLAN) is easier and less expensive to set up than a wired network, and gives employees and guest users quick, convenient access to the Internet from anywhere in your office.
Deploying a wireless network is easy in part because the networking equipment, including wireless routers and wireless access points, ships with important configuration settings preconfigured. However, these preset passwords, along with other improperly set configurations, can lead to catastrophic breaches in network security. To ensure your wireless network is secure, the devices must be configured to block intruders and protect users.
Here are five changes you can make to your WLAN configuration settings to lock down your wireless network and provide business-class security:
