Do Bug Bounties Discourage the Quality Assurance Process?

Crowdsourced bug bounties, referred to as VRPs (Vulnerability Rewards Programs), have been incredibly effective in producing bug free software in a cost efficient manner. Yet do these incentives for the crowd act as a disincentive the development team?

The resource: their consumers.

Industry giants such as Google, Microsoft and Mozilla have all implemented some form of Vulnerability Rewards Programs (VRPs) in order to create some kind of financial incentive for general users who are technically capable in identifying and resolving bugs they encounter.

And it is working. At least according to data released from U.C Berkeley.

In a paper published by Matthew Finifiter, Devdatta Akhawe and David Wagner entitled "An Empirical Study of Vulnerability Rewards Programs"; the return of investment from these programs seemed incredibly cost effective. Over a three year period, Google's Chrome team had yielded over 501 bounties at a cost of approximately $580,000 whilst Mozilla's Firefox team yielded 190 bounties for a cost of $570,000.

When drawn in contrast to the salary earnings of a security or quality assurance team, particularly within the North American context, the benefits are staggering given the yield of work produced by the general populace.

VRPs have recently entered the pop culture mindset with public events such as Pwn2Own and Pwnium introducing the concept of organized software exploitation for security purposes to the average joe-public. With support from industry leaders such as Google, the entire bounty culture has emerged as its own niche industry with websites such as Bounty Source emerging to aggregate such bounties to a market full of hungry developers.

The problem with bounty programs as an incentive, and with crowd sourcing in general, stems from a study of social science - primarily in economic theory. By creating a more financially efficient way to deal with bugs, software vendors may lean away from investing in security audits and quality assurance; focusing more on feature development.

With software development philosophies such as Continuous Integration and Continuous Delivery gaining traction, in particular in the web development space, it may be easy to defer the quality assurance process to a crowd sourced bounty model to reduce waste and to improve the overall quality of a product.

I was trained traditionally under the PMBOK outlined by PMI (Project Management Institute) and their Quality Assurance model. A high level overview of their quality assurance process could be summarised as follows:

However the issues of the Lean and Agile philosophies don't lie within the mission statement of that line of thinking; it lies in the hands of management to misappropriate their resources and means of production.

What incentive does a developer have to go on the bug hunt?

The primary incentive should always be basic quality assurance. However, poor management would rather allocate time in developing new feature sets rather than to allocate their resources to hunt and kill bugs.

A further disincentive for development team members in identifying, fixing and refactoring code problems is the negative sociological aspects of the working environment. These team members may be seen as creating more unnecessary work in a team environment whose priorities lean towards production volume rather than to quality - an ideology all too commonplace in general working environments.

Their efforts are identified as 'waste', one of which is high-effort and low-yield in the eyes of many inexperienced (and, sadly, experienced) project or product managers.

Whilst the benefits of bounties are undeniable and good Agile / Lean practices have mechanisms in place to deter from ignoring the quality assurance process, it is only human nature to eventually accept the crowd sourced workforce as a given and move away from a thorough quality assurance process.

The philosophy of TQM (Total Quality Management) in manufacturing teaches us that development of a product should be the means to understand and meet the expectations of the consumer.

If the consumer is dictating the means of production, then would the production stage itself be the true 'waste' yielded?

Would a shift of focus away from quality assurance and more to feature set development in and of itself be prone in creating more bugs in an accelerated manner?

Google have a tiered approach in addressing VRPs and it is an approach Mozilla are shifting towards. As showcased in the UC Berkeley paper the financial return and yield was significantly greater for Google in comparison to Mozilla with a relatively similar total payout.

This makes sense because simple UI headaches should not receive the same importance to severe bugs such as performance bottlenecking or critical issues such as security exploits.

One thing that is still yet to be determined is the overall scalability of bounty programs. Browsers have a large install base so it is not particularly surprising to see a general return of investment for VRPs.

However with smaller, more niche software it may not be feasible to enable such bounty programs and expect a return of investment that would replace a security or quality assurance team.

Therein lies the danger: In an attempt to replicate success, software vendors may misevaluate the importance of internal audits in favour of a financially viable "fix a bug when they come" approach.

Speaking from personal experience, it is never fun to fix a bug that has existed on a website for years and only one random user points it out to your project stakeholders.
