A Provider's Lessons on SaaS Security

The last time I proposed that we should collectively “get over” our concerns about SaaS and cloud security issues, I was making the point that whether we think these kinds of services are secure or not, the time has come to deal with the issues in the same way we deal with security for hosted applications.

The reality is that just because you've implemented a SaaS application doesn't mean you’re necessarily any more -- or any less -- safe from security threats.

I don't believe any one technology has a lock on security. From my perspective, if there is either data of any value or personal notoriety to be gained by penetrating an enterprise, you'd better be vigilant about the apps you use - whether they are inside or outside your firewall.

A report just released by security SaaS vendor Veracode provides a great insight into the kinds of vulnerabilities they've found in the nearly 3,000 assessments they've performed. Here’s a recap of Vercode’s top findings from their assessment of 2,922 applications:

Eight out of 10 Web applications failed to comply with the OWASP Top 10, a list of the 10 most dangerous Web flaws;

Cross-site scripting is the most common vulnerability;

Third-party applications were found to have the lowest security quality;

No single method of application security testing is adequate by itself.

What I find fascinating about this report (aside from the findings themselves) is the way the company is able to draw its conclusions. The assessment application is a SaaS-based application, and the results are stored in a single datastore. This makes all their results available for aggregated research. That means it's possible to fairly easily create reports based on nearly any criteria. That’s a strength of the SaaS-based approach, and one that puts the technology at the top of my list of “great strides in computing.” On the other hand, I wonder how Veracode’s applications themselves stack up against the same tests they perform for their clients.

If you look through the report, you'll see conclusions based on application type, developer type, industry vertical, vulnerability type, time to resolve identified issues, application language, and several other top-priority evaluations.

The first two findings above are particularly interesting in that they point out that the majority of all software fails to meet “acceptable” security levels and that an Internet connection that supports cross-site scripting is the main culprit in enabling the most prevalent vulnerability.

The message I take away from this is that the easy way to be secure is to unplug the Internet connection. Unfortunately, that's increasingly impractical if not impossible in today's connected environments. The second best practice is to perform vulnerability assessments on all your applications, and where possible, include commitments to resolve deficiencies in contracts and SLAs, prior to making any business arrangements.

Security always seems to be the item at the bottom of the list that no one wants to get to or think about.  It is always 'we'll get there when we can' or 'that's good enough for now' or 'no one would really even bother to try to get into this'.

It's tough stuff - the black hats are always out there always looking for an opportunity and being paranoid about it rarely makes you friends - the cost is high, the effort is high, and it is hard to know when you've actually done a good job in the end.

I'm not proposing that Veracode is better than (or even as good as) any other provider. I take their analysis as a good look at the state of software security, which seems to be pretty poor. It doesn't seem to me that the company is looking to promote its own agenda by way of its research, other than to say that if you're using software, you probably need to be doing some testing and then some fixing. That said, I'm sure they would be happy to contract to help with those kinds of tasks.

Is Veracode any better at securing these issues than other products? It seems like just another product propaganda publication. When setting up a network, the IT department, be it one guy or twenty, has their own recommendations for security. The various products on the market will always be sniping at one another. How do you choose?

In any and all roles: writing specs, developing, error-checking, testing, deploying, maintaining, using?

Combine the report you quote with one from a couple of months ago that a similar proportion of IT professionals don't take all the obvious precautions themselves, and one might be inclined to throw one's hands up and give up. But the (very slow) progress of checklists for doctors is encouraging. Simple thing like a checklist. Check off the top ten items on this report and the one I referred to, and you probably stop 99% of all problems before they can get a foothold.

I don't think SaaS security should be talked about unless you include virtualization. The fact that multiple databases can reside on the same piece of hardware has to be a security consideration, just as much as the fact that the data is cloud-based.

Clearly there is work, as there always has been, to be done in an attempt to secure our applications over the Internet. Since identifying a problem is half the solution, what needs to be done now is to find ways to resolve the vulnerabilities identified.

Security would always be an issue, the realistic thing is to have a means of reducing its negative effect.

With instant-everything now a given, why do bank transfers still take three to five days? Surely our banking systems operate in real-time when we make a purchase using a debit card. So why should we wait as long as a week to get confirmation of a deposit that simply moves from one bank to another?

Cloud-based applications are becoming old hat at this point. But one set of applications that has been slow in moving online is those that use larger files -- specifically, images, video, and sound files. However, progress is starting to happen in this field.

Would you pay a fee to guarantee your email got delivered... and read? Even if your answer is a resounding yes, it’s difficult to find a service that can make good on that promise. After all, it’s one thing to get past the spam filters and land in your recipient’s inbox. But it’s an entirely different matter to know the receiver will absolutely read your email.

Email continues to grow despite the seemingly endless onslaught of social media sites featuring updates for hundreds of millions of people around the globe. The reason for email’s continued prominence becomes obvious when you understand that social media is a “go-to” communication method, while email is a “hear-from” communication.

The majority of enterprise resource planning (ERP) systems -- in fact, the majority of all applications in use in enterprises of all sizes today -- are server-based. The burden of maintaining and managing these systems represents a significant percentage of company time and revenue.
