Would you click if it showed on the NY Times website? - Really would you?

Yesterday Fierce CIO reported that New York Times falls victim to rogue ad. This is a trend that seems to be happening more frequently. Rogue malware ads are appearing in a lot of places these days in areas most people would trust as authoritative and reliable sources of information. It is unknown how much the rogue malware “seller” may have gotten by putting the ad on the NY Times website but they likely made something from unsuspecting users. The NY Times did suffer some amount of loss since they disabled all third party ads until the rogue ad was removed. What would you do if an ad popped up on a trusted website saying your computer was infected? Most IT professionals would disregard the message as their systems SHOULD already be protected. However, how much of the general population is not an IT professional (at least outside of their own home ;) )?

What can and should the security industry do to educate users about these social engineering tactics? Should computers be “licensed” or “permitted” to be on the internet to reduce threats to unsuspecting users? That’s a thought for you… what governing body would issue these computer use permits? What would the rate infrastructure be like - based on processor/memory or bandwidth? Where would the permit fees go? Would there be some internet oversight body that uses the fees to have inline malware filters?

Thinking out loud here folks - offer some suggestions. Your input is welcome and appreciated.

20090918 Update:

E-Week reports that there is a surge in click fraud. According to the article this is similar to the NY Times advertisement malware threat discussed above. I fear this trend will only get worse. What is a legitimate advertiser or web services organization to do?

Is unified threat management defense in depth?

An ITKE poster recently asked a great question.

Experts tout unified threat management appliances as an ideal antimalware, intrusion prevention and content filtering firewall for midmarket companies. But doesn’t this counter the long-standing security practice of defense-in-depth? With a one vendor, platform, and management console, aren’t we talking about a dangerous single point of failure?

When is UTM good enough? When should we go with standalone devices?

Here’s the answer that I offered:

Actually it is defense in depth even though they are all contained on one appliance or device. Think about the layers in a bullet proof vest. They each work in tandem to prevent damage to the person wearing it. However just one type of layer by itself would likely not be enough protection against certain firearms.

Granted it is a single point of failure, but the ability to manage an entire suite of services from one console is attractive to many smaller organizations that may not be able to provide the care and feeding of single purpose devices. The ability of a vendor to patch the entire product suite against vulnerabilities is another good reason to go to a UTM device. If using multiple devices from different vendors, then the vulnerability exposure could potentially be greater if one vendor addresses a vulnerability in their appliance/service but another does not.

I would go to standalone devices if the potential threat to my organization could create capacity/performance issues on the UTM device.

How do you think about the UTM vs defense in depth issue? Do you agree with the answer I offered? What do you think?
