Cloud CISO Perspectives: August 2022

Welcome to this month’s Cloud CISO Perspectives. This month, we’re focusing on the importance of vulnerability reward programs, also known as bug bounties. These programs for rewarding independent security researchers for reporting zero-day vulnerabilities to the software vendor first started appearing around 1995, and have since evolved into an integral part of the security landscape. Today, they can help organizations build more secure products and services. As I explain below, vulnerability reward programs also play a key role in digital transformation. As with all Cloud CISO Perspectives, the contents of this newsletter will continue to be posted to the Google Cloud blog. If you’re reading this on the website and you’d like to receive the email version, you can subscribe here.Why vulnerability rewards programs are vital to cloud servicesI’d like to revisit a Google Cloud highlight from June that I believe sheds some light onto an important aspect of how organizations build secure products, and build security into their business systems. On June 3, we announced the winners of the 2021 Google Cloud Vulnerability Rewards Program prize. This is the third year that Google Cloud has participated in the VRP. The top six prize winners scored a combined $313,337 for the vulnerabilities they found. An integral part of the competition is for the competitors to publish a public write-up of their vulnerability reports, which we hope encourages even more people to participate in open research into cloud security. (You can learn more about Google’s Vulnerability Rewards Program here.)Over the life of the program, we’ve increased the awards—a measure of the program’s success. And we’ve also increased the prize values in our companion Kubernetes Capture the Flag VRP. These increases benefit the research community, of course, and help us secure our products. But they also help develop a mature, resilient security ecosystem in which our internal security teams are indelibly connected to external, independent security researchers. This conclusion has been borne out by my own experience with VRPs, but also independent analysis. Researchers at the University of Houston and the Technical University of Munich concluded in a study of Chromium vulnerabilities published in 2021 that the diverse backgrounds and interests of external bug-hunters contributed to their ability to find different kinds of vulnerabilities. Specifically, they tracked down bugs in Chromium Stable releases and in user interface components. The researchers wrote that “external bug hunters provide security benefits by complementing internal security teams with diverse expertise and outside perspective, discovering different types of vulnerabilities.”Although organizations have used VRPs since the 1990s to help fix their software, and their use continues to grow in popularity, they still require forethought and planning. At the very least, an organization should have a dedicated, publicly-available and internally-managed email address for researchers to submit their reports and claims. More than anything else, researchers want to be able to communicate their security concerns to somebody who will take them seriously.That said, incoming vulnerability reports can set off klaxons if the preparations have not been put in place to properly manage them. A more mature VRP will triage incoming reports and have in place a more rigorous machinery which includes determining who will receive the reports, how the interactions with the researcher who filed the report will be handled, which engineering teams will be notified and involved, how the report will be verified as accurate and authentic, and how customers will be supported.There’s an opportunity for boards and organization leaders to take a more active role in kickstarting and guiding this process if their organization doesn’t have a VRP in place yet. Part of what makes VRPs so important is that they bring benefits beyond the obvious. They can help teams learn more, they can strengthen ties to the researcher community, they can provide feedback on updating internal processes, and they can create pathways to improve security and development team structures.Ultimately, the business case for a VRP program is simple. No matter how great you are at security, you still are going to have some vulnerabilities. You want those discovered as quickly as possible by people who will be incentivized to tell you. If you don’t, you run increasing risks that adversaries will either discover those vulnerabilities or acquire them from an illicit marketplace. As more organizations undergo their digital transformations, the need for VRPs will only increase. The web of interconnectedness between a company’s systems and the systems of its suppliers, partners, and customers will force them to expand the scope of their security concerns, so the most responsible behavior is for organizations to encourage their suppliers to adopt VRP programs.Google Cloud Security TalksSecurity Talks is our ongoing program to bring together experts from the Google Cloud security team, including the Google Cybersecurity Action Team and Office of the CISO, and the industry at large to share information on our latest security products, innovations, and best practices.
