We All Share Responsibility to Secure Code

We All Share Responsibility to Secure Code

It's indisputable that open source software is an essential element in application development worldwide. Its benefits in reducing dev costs, promoting innovation and accelerating time to market explain why open source often comprises more than 50% of an application's code.  

There is, however, an ongoing - and often very heated - debate about whether open source is more or less secure than commercial software. In my view there is no convincing argument that open source is any less secure, or any more secure than commercial software.

It's software, folks. There will always be bugs in open source and in commercial software.

Unfortunately, after some recent comments I made about open source security were published in adtmag.com, TechRepublic columnist Matt Asay took exception with them in an article headlined “Why it's time to stop blaming open source for ransomware attacks.”

Matt read my comments as blaming open source for having vulnerabilities. I would assign no such blame, and in fact I suspect that Matt and I are in full agreement on this subject.

Blaming Software?

Indeed “blaming software” would be a pretty silly. Software doesn’t write, deploy, or manage itself. Humans do and if there is any blaming to be done, it falls on us.

My argument isn’t that open source code is less secure code, nor “that open source is ultimately to blame for attacks.” Instead, my argument is that if you aren’t aware of what open source you’re using, or where it is in your code base (and code audit analysis reports released by Black Duck’s global Center for Open Source Research and Innovation consistently show most organizations do not) you simply cannot update the components when vulnerabilities are disclosed.  

As Matt stated in his piece, if companies keep careful track of both the code they are using, then “enterprises can also consult [the National Vulnerability Database] and plug the holes” as any new vulnerabilities are disclosed.

This is true, but not what we see in practice. Instead, we see mature organizations using more than twice as many open source components as they reported they have, with the average age of vulnerable components at more than five years. Lack of visibility means lack of control and the result, as we've seen in high profile, open source breaches, can be costly.

Secure Code

This isn’t because open source is less secure than commercial code – and I’m not “blaming open source.” This responsibility falls squarely on the organizations using the open source, but not securing and managing it effectively.

Regarding the attractiveness to vulnerabilities in open source as an attack vector, I stand by my comments. Again, this isn’t blaming the open source. It’s simply that hackers understand that companies do not track their open source carefully, and, as shown, that vulnerable components are not always addressed.

So Matt, I think we’re on the same side here.

This is the first in a series of posts about how organizations can best apply their security resources to vulnerabilities in open source components. Almost every security lead I speak to would love to have more security resources. Whether it’s people to conduct threat modeling, manual code
