In light of the growing amount of broadband users, I've decided to make a page about broadband Internet security.
Security seems to be the last thing people think about when it should be the first. It takes a sluggished compromised system for most users to considered examining their system.
There are plenty of broadband pages out there but I wanted mine to be a simple walk through for the average compuer user.
Broadband a security issue
My friend around the corner calls me about once a month to clean up his computer. Usually, its just a simple matter of running
Adaware or HiJackThis. But this time was different.
was helping my partner clean a trojan off of his Dell the other
day. And to my surprise Adaware did not remove it. It also
removed the ability to get to the Task Manager in order to view the
processes and added a link to the desktop.
I found out it was called TROJAN–SPY.HTML.SMITFRAUD. It took more effort than usual to remove, but I did manage to get rid of it with the help of
a the Geekstogo! Malware removal forum. I've found forums to be VERY helpful in getting help cleaing up and securing my home computer with ease. Here is how I got rid of the Smithfraud.

I’ve finally stopped procrastinating and joined my local Information System Security Association, Colorado Springs Chapter (ISSA-COS). A few of my co-workers have been encouraging me to join since last year.
Over the past year many of the benefits that they’ve enjoyed as member of the ISSA have spilled over on to me. I
encourage all serious Information security professional to join because
the ISSA has their fingers on the pulse on all information security
events, jobs and seminars at discount prices.
ISSA members are always up on the latest security events and seminars in town. Just two months ago, an ISSA member invited me to attend an Certified Ethical Hacking course. I actually had no idea that there was a “hacking certification” prior to her email. I attended a free seminar with mile2 and loved it so much I decided to attend the whole course. I was able to attend an Ethical Hacking Course which my company paid for. I’ll be going for that cert. soon.
As an ISSA member you will have access to many information security jobs in the area and around the world. Recently, one of my former co-workers (ISSA member) sent me information on an information security job in Baghdad. For fear of being apart of a hostage reality show on Al Jazeera TV, I declined. Would you decline a 300K/year job? I must admit I think about it every now and then. My co-worker actually took the job and is much braver than I am.
Discounts on events, seminars and training is another benefit of an ISSA member. For
example, we are having a local Security+ training that will be held
this Saturday at Colorado Technical University and in May there will is
the SANS Rocky Mountain 2005 – Immersion Training which gives a price cut to all members.
In my opinion, the best thing about the ISSA is the ability to network with like minded Information Security professionals. In the local ISSA Chapter there is a meeting once a month with seminars and meetings that include speakers like Phil Zimmerman, creator of PGP and representatives from companies like 3Com’s, TippingPoint.
If you are an information security professional, you should definitely sign up. Membership is free for 90 days to give you feel for the association (attend a meeting with your 90-day membership). It
is $99.00 a year for ISSA membership and an additional $25.00 for the
Colorado Springs ISSA division (each local chapter has its own annual
fee). Don’t be like me and wait a year to join. The networking is worth your weight in gold or at least 300K/year in an exotic location.

Building a Network:
Seth Godin has a good post about building a network.
· MAC (Mandatory Access Control)
· DAC (Discretionary Access Control)
· RBAC (Role Based Access Control)
To understand MAC, DAC and RBAC you must first understand Access Control.
Access Control is the control of user and process control access to network and operating system resources. For example, many spyware and adware applications not only download themselves on to your computer without your permission, but they also help themselves to your systems CPU, hard drive and memory. What happens to most of us is that we get hit with 10 or 15 of these applications by accessing the Internet without protection. Imagine 10 to 15 badly written memory hogs using your CPU and memory to access your cached references to your web surfing habits (or worse credit card, ssn) and send that potentially valuable information to some server in Nigeria or Russia.
Mandatory Access Control (MAC)
Mandatory Access Control is military grade security. Like DAC, it has been around since the 60’s. With MAC, the security on all resources are strictly policy controlled. All processes and users (or subjects) must specifically given permission to access a resource (or object).
Subjects are given a number indicating their level of access. Subjects can access any object with a lower number. With modern military and national security systems this permissions matrix is supplemented with a classification level.
Discrestionary Access Control (DAC)
Discretionary Access Control is where a subject has control over an object. In this case a “subject” could be a home user. And lets say the home user has admin privileges because he wants to download applications like Kazaa Lite ++. The “object” or resource is Money Quick, a financial application that creates important bank account spreadsheets.
The home user is no fool so he locks the Money Quick application down so that only the administrator has permissions to the file. She is the only administrator on the computer so there is no problem right? Wrong. With DAC any application that runs while the current user is logged on has the same permissions.
So, the home user finds Kazaa Lite ++ on Internet and downloads it. The shareware app is of course loaded with all kinds of spyware, adware, Trojan filth that goes directly for her Money Quick software.
Is very popular and has been in use primarily in the commercial and academic worlds since the ’60’s.
Role Based Access Control (RBAC)
Role Based Access Control is fairly new and is considered the evolution of the DAC & MAC. With RBAC, each subject is assigned a role. Users without roles can be put into groups that pertain to a certain department or job such as sales or management. Objects only allow subjects on a permission basis. Modern operating systems such as Solaris, Linux and Window 2k/XP/03 are perfect example of how Role Based Access Control works.
The RBAC started in the 1990s and fully materialized in the RBAC96. There is currently a lot of research being done on the RBAC.
