Scott Blake, CISSP Vice President of Information Security BindView Corporation/RAZOR Research The Politics of Vulnerabilities
Agenda • Introduction • What is Politics? • What is a Vulnerability? • The Past and Present • Ideologies, Actors, and Initiatives • The Future • Trends and Probabilities
What is Politics? • The study of power • Power is the ability to make one do what one would not otherwise do. • Important Terms • Actor: One who uses or is subject to power • Ideology: A set of beliefs or ideas • Legitimacy: In accordance with established standards or patterns • Authority: Legitimate power
What is a Vulnerability? • Experts do not agree • Flaws in Software • Misconfigurations • What do vulnerabilities do? • Change user context • Crash systems or services • Execute arbitrary code • …
Ideologies • Full disclosure • Responsible Disclosure • Zero disclosure • Limited Disclosure
Full Disclosure • Tenets • Information wants to be free • Use the power of public opinion to make vendors improve code • Exploit code is more useful than destructive • Adherents • Most non-profit researchers • Very few commercial researchers
Responsible Disclosure • Tenets • Exploit code causes more problems than it solves • Broad dissemination of vulnerability information is required to improve security awareness • Use the power of public opinion to make vendors improve code • Adherents • Most commercial researchers • Some notable software vendors
Zero Disclosure • Tenets • Responsibility for fixing vulnerabilities lies with software vendor • Authors of software should control information relating to that software • There is no public good in broad availability of vulnerability information • Adherents • Many software vendors • Many government actors • Much of the Public
Limited Disclosure • A variant of Zero Disclosure • Same Tenets and Adherents • But supports complete information sharing on a Need-to-Know basis within peer groups • Implemented in US Information Sharing and Analysis Centers (ISAC) and others
The Actors • Vendors • Researchers • The Underground • Governments • Media • The Public
Vendors • Motivators • Shareholder value • Financing • Software Sales • Interests • Limit damage to brand value • Limit vulnerability of customers • Sell more software • Power Relations • Often try to prevent public disclosure of vulnerability information through legal action, market leverage, lobbying
Researchers • Motivators • Advance state of the art • Build more security • Build name recognition/peer respect • Financing • Day Job • Customers (Grant, Contract) • Software sales
Researchers (2) • Interests • Continue financing source • Maintain/extend reputation • Power Relations • Hobbyists are largely free from external influence providing the day job does not interfere • Academic and consultative researchers are largely beholden to their funding source, but different funders set different restrictions • Commercially-sponsored researchers are beholden to the parent company’s interests
Researchers: The Underground • Same as other researchers, plus: • Motivators • Control, knowing something that other don’t • Financing • Some organized crime or other illegal sources • Interests • Maintaining the status quo • Power Relations • Wield little power except to cause fear among other Actors
Governments • Motivators • Technocratic perception of public good • Financing • Taxes • Campaign Contributions • Interests • Economic growth • Public Safety • Power Relations • Prosecution of criminal or negligent behavior • Large purchaser of information technology
The Media • Motivators • “All the news that’s fit to print” • Financing • Advertisements • Subscribers • Interests • More readers • Power Relations • Very powerful creators of brand, image • Influencers of public perception
The Public • Motivators • Too chaotic to be relevant • Financing • Too chaotic to be relevant • Interests • Stable, secure software • Whiz-Bang Features • Power Relations • Wields tremendous power, but very difficult to direct in any specific direction
Policy Initiatives • Council of Europe’s Cybercrime Treaty • US Information Sharing Policies • Disclosure Forums • Organization for Internet Safety • Various US Legislation
Council of Europe’s Cybercrime Treaty • Intended Outcomes • Harmonize and update European computer crime laws • Unintended Outcomes • Potential for mis-implementation of tools provisions may have chilling effect on research • Language pertaining to intent may lead to certification requirements for security practitioners
US Information Sharing Policies • Intended Outcomes • Stay one step ahead of the bad guys • Facilitate movement of information among legitimate parties: Government and ISACs • Better intelligence on attacks • Unintended Outcomes • Chilling effect on public discussion • Creates information haves and have-nots
Disclosure Forums • Intended Outcomes • Get information to those who need it • Unintended Outcomes • Puts information in the hands of the “bad guys” • Examples • Bugtraq • NTBugtraq • Win2KSecAdvice • Cypherpunks • Vuln-Dev • And many more
Organization for Internet Safety • Intended Outcomes • Limit availability of information to “bad guys” • Unintended Outcomes • Limit availability of information to everyone • “Chilling Effect” on research in general
Various US legislation • FOIA and Anti-Trust exemptions for security-related information sharing • Increasing funding for NIST and NSF sponsored research • Single “Gold Standard” for US government system security configurations • FISMA: Revised reporting regulations for government agencies • DMCA and PATRIOT Act
Trends • Increasing legislation • More clear definitions of cybercrime • Will the definitions be correct? • Improving communication channels • Information is being shared better among the “good guys” and the “bad guys” • More and more research being done • Rate of new vulnerability announcements has been increasing at ~90% per year since 1992
Trends (2) • More vicious attacks • Nimda was the most aggressive worm yet, though still not terribly damaging, but very expensive to clean up • Continuing penetration of Internet access • The number of devices has topped 100 million and the rate is set to skyrocket with wireless Internet devices
Probabilities • Will the public demand security? • Probably not • Who will pay for security? • Consumers? Government? Vendors? • Lessons from recent events • HP DMCA threat • Security for the people? • Personal firewalls, privacy regulation (HIPAA, GLBA), NCSA • Will liability laws change? • Probably not
Conclusions / Predictions • No major changes are imminent • Continued harmonization of laws • Continued creation and discovery of flaws • Continued mismanagement of flaws • Continued small-scale exploitation • Absent a catastrophe, no major changes will occur at all • Software drifts toward being more secure, but the progress is offset by increasing complexity
