DX and Open Sourcing at Netflix
In this Speaker Series presentation, former cloud architect for Netflix and now Battery Ventures technology fellow Adrian Cockcroft discusse...
Security vulnerabilities are a reality that every team must face at some point. We asked Mårten Mickos, CEO of HackerOne and members of his security team to share their thoughts on the importance of vulnerability disclosure, the move towards responsible policies, and what teams should do as they prepare to create their own vulnerability disclosure policy.
Vulnerability Disclosure used to be an obscure practice that only the most responsible or progressive companies and organizations would engage in. Today, it is becoming a best practice. It is part of NIST’s cybersecurity framework which probably is the most used framework of its kind. Nearly all startups have a security@ email address where they receive vulnerability reports from the outside. The DoD is working on a new capability model called CMMC, where every vendor to the Pentagon will be required to be able to receive, analyze and take action on vulnerability submissions.
(CMMC says: “The organization has processes established to receive, analyze and respond to vulnerabilities disclosed to the organization from internal and external sources.”)
It’s important to include the boundaries of what you will and won’t do in your policy. Be very explicit about what assets are in-scope, how you wish to communicate with hackers and how you will legally treat those that are trying to work with you — by adopting a safe harbor policy. As we all know, vulnerabilities are in your software and people will find them either intentionally or unintentionally. Anything short of a clear responsible policy will reduce or eliminate the possibility that these vulnerabilities will be disclosed or resolved.
The word “responsible” was added years ago when people worried about irresponsible disclosure and saw other risks. Today, with the vulnerability submission and handling process pretty well defined for all stakeholders, we could consider dropping that word. The vast majority of all hackers will disclose vulnerabilities in the right way to companies, and increasingly companies know what to do once they receive such a report.
Several traditional behaviors of information security were established before the world became always connected through the internet. In the security profession, there was secrecy, isolation, siloing and belief in perimeter defense. There was a belief that complete security can be achieved. Many practices were established to protect individuals from culpability more than protecting the actual computer systems. As a result, engaging with an external community of security experts was not understood.
To see the immense value of responsible vulnerability disclosure, you need to start by acknowledging that all software has vulnerabilities. Secondly, you need to believe that people on the outside of the organization are to the largest extent people with good intent whose help can be useful. Thirdly you need to realize that you are in better shape, not worse shape, when you know about a vulnerability compared to not knowing. Fourth, no matter how hard it may be to fix a bug, you need to come to the insight that every bug can be fixed or access to it can be blocked, i.e. there is always a cure.
The first action is to obtain alignment internally and commitment from the software engineering teams to fix the most critical vulnerabilities when they are reported.
Opinions may vary, but the initial promise is quite a substantive commitment to live up. The success of a vulnerability disclosure program depends on the everyday attention to whatever hackers are reporting to the organization. Staying on top of the queue and always responding promptly to hackers takes some discipline – and leads to success of the overall program.
The following are some great resources for learning more about vulnerability disclosure and cybersecurity policies:
Additionally, you can find a wide range of existing vulnerability disclosure programs that are worth reviewing as you build your own:
Security has taken a more central role in the business strategies of growing companies, and knowing how to approach security effectively is key. At DevGuild: Enterprise Security, we learned from CISOs of organizations like Splunk, Atlassian and HashiCorp about how to create strong security processes.
