Hi all,

One thing that really surprises me these days is the amount of home users who still do not have a clue about security. They are still using WEP and are not formatting SD and other flash media correctly. This seem to make them very easy targets for being attacked.

Companies these days have the money to pay for security experts to come and test their security. But should security begin at home? Should home users have better access to security resources? If home user had better training would they not go to work more aware and think twice about writing password on post it note?

What do you think? Do you think the government should take steps to make home user more aware about security?

I'll do you one better....some of those home users you're talking about that use WEP (or nothing at all) are the CEO's, Presidents, VPs of your company. Why attack a corporate network that generally has some security controls built in when I can find the home address of your CEO, President, VPs and attack their juicy, EASY network? Where do you think they VPN from anyway?

My point is home security should be part of your training program, especially for VP/C-types...

The majority of home users will have client side attacks affect them, ie phishing emails etc

My home computer security isn't as tight as I would like it to be, but it still alot better than most

Company's tend to have open ports in the DMZ for emails etc whereas the majority of home users do not

Sacraficing security to send/receive a few emails?

Well that my opinion, security definiately starts at home for sure, but like most its not a priority as they don't think they have anything on the PC worth anything even though they do online banking lol

Agreed, most home security isn't great, but for the most part it could be as secure as it needs to be. Investment (time, cash, resources) into security above the level of the value of the protected assets doesn't provide a good ROI.

It's easy for use as security people to scoff at the inability of 'normal' users to secure their systems, but this is what we do. On the flipside; I drive a car, but have no (indepth) idea of how it runs, or how to fix if it breaks. Despite the mechanics that I know telling me that it's simple. There just isn't enough time to know all topics indepth, and for most, computer security isn't a priority.

Wireless (in)security is rife though, I did some wardriving a while back (and need to re-do to see if there has been any change/improvement), almost 50% of all APs were either running WEP, or completely open (findings here.) I'm guessing one problem may be compatibility issues, from my own experience I have an older Nintendo DS that can only communicate with open or WEP networks.

Whilst increasing home network security is a good goal to work towards, if we did provide average users with greater access to security resources and knowledge, would they be interested enough to take advantage? I'd argue that they already have all the resources they need online...

I agree so far with the comments. And yes there are alot of resources online I think the main problem is understanding them. For example there are repair guides for cars online, does not mean I could repair my car.

I just think many home user are blind to the problems they could face when online or at home. And if they were more aware of the risk and had a way to mittigate that risk they would take advantage of it.

I mean I dont yet work in security so I may not know excatly the process a security expert takes. However I work in PC Technician and when customer come in with a Virus/Malware or they been social engineered over the phone by someone making out there from google or miscrosoft. When I take time to explain what happen, why it might of happen, and what could of happened they are really shocked.

I'll be the DA on user education, Most users are aware of the threats they face, and are aware of at least some of the steps they should be taking, but they cant be forced to do it. Many companies have IS training programs I persume, but how many users, at home or at work, are that keen to sacrifice usability and ease of use for security?

A great example is email, there shouldnt be a person online over the age of 18 who hasnt heard "dont click on links in emails saying your account has been suspended, please click here... or your uncle in Jamaica had 13 million, send us your info..." and yet users still fall for these scams.

We have an annual check of our IT systems by an external agency at work and one of the things that is always picked up is the number of people with weak passwords only minimally changed from the default password issued with a new account or p/w reset.

As people now start working at our place they get a brief on the do's and don'ts of the works IT which i've expanded to include a few 'good ideas' on PC and internet security, especially on the web.

Have plotted a few graphs for brute force attacks against different lenghts of passwords both simple and complex.  This usually shocks people when they see the figures, especially when I tell them that this is based off one PC doing the cracking and a good hacker could have several hundred bot pc's to assist in the task.

Show them a screen shot of an actual phishing web page I found one day and explained how the code behind it worked. I then ask the $1000 question...
'If I captured your username and password off this page, how many of the following websites could I log into?' 
I bring up a slide showing most of the popular sites that you need to log in to and point out that most of these list your e-mail address within your profile so that could potentially give me access to your mail account as a spam relay.

The brief does make some of them think about what they're doing and i've actually had a few people contact me a few days after the brief to clarify or expand on what i've said.

the last place I worked, the majority of my "Network Traffic Audits" was looking for people who were showing the most traffic in BandwidthD for the day. When I started, only 1 server was in the list of top 10. I think there were 3 more at the bottom of the top 20.

And the users really did say, "but I'm only listening to music from YouTube in the background. It doesn't download the video if {insert browser of choice here} is minimized."

It was a cycle, every 6 months or so. Management would only care when the majority of the users (same ones downloading videos) would complain about network slowness. I'd show them the problem, and it would "be dealt with" reminding the users they can't do that in hand book, some would be walked out for "last straw". Then because the network was better they wouldn't pay as much attention, and it would start all over again.

I was never able to get a proxy server in place to prevent that, because "it'll prevent them from doing their jobs".

As for your phishing example, even the Pros get caught sometimes. Robin Sage? Spam however works. Someone has to be clicking it, or the online pharmacies and the like wouldn't still be in business to pay the spammer.
