OWASP Developer Guide Define Security Requirements Checklist OWASP Foundation
Each technique or control in this document will map to one or more items in the risk based OWASP Top 10. After the need is determined for development, the developer must now modify the application in some way to add the new functionality or eliminate an insecure option. In this phase the developer first determines the design required to address the requirement, and then completes the code changes to meet the requirement. Stay tuned for the next blog posts in this series to learn more about these proactive controls in depth.
Access Control functionality often spans many areas of software depending on the complexity of the access control system. For example, managing access control metadata or building caching for scalability purposes are often additional components in an access control system that need to be built or managed. There are several different types of access control design that should be considered. The answer is with security controls such as authentication, identity proofing, session management, and so on. You should normally avoid implementing security-related controls from scratch unless you really know what you’re doing—doing so requires deep knowledge and expertise to implement them in a reliable and secure manner. Attackers targeting your application or library will use techniques that can abuse tiny issues in your code.
Developer Guide (draft)
Our freedom from commercial pressures allows us to provide unbiased, practical, cost effective information about application security. However, development managers, product owners, Q/A professionals, program managers, and anyone involved in building software can also benefit from this document. The ASVS requirements are basic verifiable statements which can be expanded upon with user stories and misuse cases.
In this blog post, I’ll discuss the importance of establishing the different components and modules you’ll need in your project and how to choose frameworks and libraries with secure defaults. Two great examples of secure defaults in most web frameworks are web views that encode output by default (providing XSS attack defenses) as well https://remotemode.net/ as built-in protection against Cross-Site Request Forgeries. So, I’ll also show you how to use invariant enforcement to make sure that there are no unjustified deviations from such defaults across the full scope of your projects. This approach is suitable for adoption by all developers, even those who are new to software security.
The Top 10 Proactive Controls
Interested in reading more about SQL injection attacks and why it is a security risk? The OWASP Top Ten Proactive Controls describes the most important controls and control categories that every architect and developer should absolutely, 100% include in every project. Probably the best advice on checklists is given by the Application Security Verification Standard (ASVS).
For example, SQL commonly uses single (‘) or double (“) quotation marks to delineate user data within a query, so user input containing these characters might be capable of changing the command being processed. When your application encounters such activity, your application should at the very least log the activity and mark it as a high severity issue. Ideally, your application should also respond to a possible identified attack, by for example invalidating the user’s session and locking the user’s account. The response mechanisms allows the software to react in realtime to possible identified attacks. All access control failures should be logged as these may be indicative of a malicious user probing the application for vulnerabilities.

Snyk interviewed 20+ security leaders who have successfully and unsuccessfully built security champions programs. Check out this playbook to learn how to run an effective developer-focused security champions program. Snyk provides one-click fix PRs and remediation advice for your code, dependencies, containers, and cloud infrastructure. Make sure you track the use of open source libraries owasp proactive controls and maintain an inventory of versions, their licenses and vulnerabilities such as OWASP’s top 10 vulnerabilities using tools like OWASP’s Dependency Check or Snyk. Recently, I was thinking back at a great opening session of DevSecCon community we had last year, featuring no other than Jim Manico. Use the extensive project presentation that expands on the information in the document.
In order to achieve secure software, developers must be supported and helped by the organization they author code for. As software developers author the code that makes up a web application, they need to embrace and practice a wide variety of secure coding techniques. All tiers of a web application, the user interface, the business logic, the controller, the database code and more – all need to be developed with security in mind. This can be a very difficult task and developers are often set up for failure. The languages and frameworks that developers use to build web applications are often lacking critical core controls or are insecure by default in some way. It is also very rare when organizations provide developers with prescriptive requirements that guide them down the path of secure software.

This preserves data from any node that may be compromised, and facilitates centralized monitoring. There are very good peer-reviewed and open-source tools out there, such as Google Tink and Libsodium, that will likely produce better results than anything you could create from scratch. Cryptographic authentication is considered the highest form of authentication and requires a person or entity to have proof of possession of a key through a cryptographic protocol.
