Mobile devices are in the workplace already. Because they are designed to hook into existing information systems, their users have the ability to quickly and easily access the wireless network, email servers, application servers, and file shares that would be available to any PC on the network. But unlike PC’s with their well documented vulnerabilities and widely deployed anti-virus suites, tablets and smartphones have no built in protection. If an organization wants to protect their … Read the rest

11:29 pm
This last weekend I almost lost all the pictures. We have four kids, and have tons of pictures. I had set up the user accounts on our Mac on an external mirrored drive, connected by Firewire. This was mostly good, but this weekend all the applications just refused to connect because of some kind of weird permissions issue. I went through all sorts of stuff to get it working, but at the end of the … Read the rest

4:16 pm
Viruses, trojans, malware, and other problems routinely crop up on Windows machines – they are a fact of life. I just refreshed my computer troubleshooting skills on a Windows 7 laptop that was unusable. It had been taken over by a fake computer security application that was demanding money to continue allow the PC to continue to work. I really did not want to go through and reimage the machine – I just wanted the … Read the rest
Where Does Security Start and Stop

Security is everywhere – First the definition is vague
1. freedom from danger, risk, etc.; safety.
2. freedom from care, anxiety, or doubt; well-foundedconfidence.
3. something that secures or makes safe; protection; defense

Most organizations use single-factor authentication to provide security to important information and resources. That is now being recognized to be insufficient to protect sensitive data from loss due to malicious hacking activity. Hackers use advanced dictionary attacks, social engineering, and key-logging to obtain the passwords they need to remotely enter systems and steal sensitive data like credit card numbers complete identity information.
If a username and password can be guessed or discovered, malicious hackers from … Read the rest

It has been a long time since Cisco released zone based firewalling for the ISR. They have been “threatening” to take away my CBAC for some time, happily they still haven’t done it, but the writing is on the wall.

Is MAC address filtering really the way to go? People have been using this as a layer two method of controlling access for a long time, but it is easily bypassed. There are now more dynamic methods available that will help maintain a secure infrastructure.
MAC address filtering can be easily bypassed by simply finding a machine that is working and steeling its MAC and put it on your computer. In all major operating systems … Read the rest
