The presentation
This presentation is given as part of OWASP Software Assurance Day at the | 13th Annual Software Assurance Forum.
The speaker
Dave Wichers is a cofounder and the Chief Operating Officer (COO) of Aspect Security, a company that specializes in application security services.
As a volunteer to OWASP, Dave is:
- A member of the OWASP Board,
- The OWASP Conferences Chair,
- Project lead and coauthor of the OWASP Top 10,
- Coauthor of the OWASP Application Security Verification Standard, and
- Contributor to the OWASP Enterprise Security API (ESAPI) project.
Dave has over 20 years of experience in the information security field, and has focused exclusively on application security since 1998. At Aspect, in addition to his COO duties, he is Aspect's application security courseware lead, one of their chief instructors, and provides a wide variety of application security consulting services to Aspect's clients. Prior to starting Aspect, he ran the Application Security Services Group at Exodus Communications. Dave has a Bachelors and Masters degree in Computer Science, is a CISSP, and a CISM.

Notes
Getting Started with the Top Ten and OWASP Guides – Dave Wichers We are still not asking for secure software. Is your customer really asking you to create secure software? There is a fundamental supply and demand problem. No one will produce something that no one wants to buy. If software firms spend the effort to build secure software, then it increases the cost. If it has the same functionality but has the invisible feature of security, then no one will buy it yet. We as consumers must demand security from these companies we patronize. Microsoft has worked very hard to produce secure software. Some vendors are starting to win contracts because their software is more secure.
Microsoft was seeing roughly 8 – 15% of up front costs, but then saw costs drop dramatically due to efficiencies and cost avoidance. Investing in software quality can also provide a means for cost reduction which is a huge culture problem.
Startups only care about marketshare, not security. Small companies should have security as a priority as they gain a certain portion of marketshare.
Open Source is not necessarily more or less secure. It varies. DHS’ HOST program and another site setup in partnership with Coverity provide feedback to open source developers.
When Wichers works with the DISA STIGs he look at the code to see if it is secure. If he finds something, they fix it. If not, then they don’t fix it. They are focusing on verification. If there is enough flaws found, then they might ask if there is a better way to build security in. But if we don’t demand security then we won’t get it.
Wichers discussed half a dozen projects, but OWASP has many more in various levels of maturity. There is a bar at the top of the OWASP website that lists some of the most mature projects. The OWASP meritocracy allows members to start new projects and then gain traction. There are slide decks on each OWASP project available online.
Many are listing OWASP references in either strong or weak ways. PCI point directly to the OWASP Top 10 despite having no formal relationship. The DISA STIG makes many references to the Top 10 for more information.
Top 10 Web Application Security Risks
The first step to helping developers is to make them aware of the issues. The Top 10 is a broad brush awareness document for any community. But it won’t provide all the details. If you don’t understand the technical foundation of the problems then you can’t build code to be secure against them.
The Top 10 helps developers to understand risk. Businesses must understand the risks and how significant they are. The business must understand the gravity of the ramifications if this risk is exploited. Until the business understands the risk, they won’t do anything about it.
The managers must care for the developers to care. The Top 10 includes a section stating that it is related to risk instead of just technical specifications. Businesses understand and are concerned with risk. Everything is a cost-benefit balance.
The attacks are becoming extremely professional and advanced. Economic pressures may not come as strongly from the consumers who are “path-of-least-resistance driven” but business-to-business pressure will be much stronger. This has been seen in the credit card processing industry. Google removed all of its internal Microsoft operating system installations after the Chinese hack.
The OWASP material ranges from understanding risk, to avoiding risk, to measuring risk, to managing risk.
Microsoft has statistics about the cost of the appsec program being zero or negative because the cost of rework outweighs their investment. This information is publicly available. Over time the up front cost is reduced.
The Top 10 was created in 2003. Each year it has been condensed so it is easily consumable. The Top 10 was always about risk, but making this distinction has been made clearer. Although some flaws may be less prevalent, they are just as devastating when exploited. The Top 10 is prioritized based upon the OWASP Risk Rating Methodology.
The OWASP Prevention Cheat Sheet provides article on how to avoid the most common web security problems. They are all interlinked. They include very concise guidance for developers.
The OWASP Application Security Verification Standard (ASVS) provides a standard for how to verify security services. This helps organizations to compare application security service vendors. The ASVS is a positive model stating what should be found. The byproduct is a comprehensive roadmap of requirements which other OWASP ecosystems could leverage. The standard is our opinion of what should be included. The ASVS is a verification standard and is organized in terms of level of difficulty. This is why automated verification is at level 1 and design verification is at level 3.
The government needs to ask for secure software in any form. The OWASP Legal Guide facilitates the requiring of secure software in contracts. Its use would require a smart purchaser of security to require it of their vendor and having it as a factor of competitive bidding.
Q. Have any vendors adopted the legal language? A. A few companies have experimented with the legal language.
The OWASP Developer Guide was the original flagship document. The document has languished but there is a team that is working to update it.
Developers need secure controls to build secure software. This document explains the intent of this statement. It outlines the standard set of controls needed and provides an explanation of the implementation. It outlines standard control implementation in many popular languages. The ESAPI source code is a great example of secure code. There are plenty of other free OWASP tools online as well.
The OWASP Code Review Guide outlines approaches to code review, reporting, metrics, etc. by example within various languages. It will soon be aligned with the ASVS.
The OWASP Testing Guide may be the largest OWASP project in terms of the number of contributors. This may be the most popular guide due to the number of people trying to perform testing.
- OWASP Common Numbering project organizes the guides in the same standardized order.
