In this series, I’m going to introduce the OWASP Top 10 Proactive Controls one at a time to present concepts that will make your code more resilient and enable your code to defend itself against would-be attackers. When possible, I’ll also show you how to create CodeQL queries to help you ensure that you’re correctly applying these concepts and enforcing the application of these proactive controls throughout your code. I served as a postal police officer in Chicago for 22 years until my retirement in 2017.
- This document will also provide a good foundation of topics to help drive introductory software security developer training.
- They are ordered by order of importance, with control number 1 being the most important.
- This threat vector, in which attackers enforce requests on behalf of an application server to access internal or external resources, is becoming more and more popular.
- No matter how many layers of validation data goes through, it should always be escaped/encoded for the right context.
- The Top 10 Proactive Controls are by developers for developers to assist those new to secure development.
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. Most developers did not learn about secure coding or crypto in school. 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.

Various attack vectors are opening up from outdated open-source and third-party components. APIs and applications using components with known vulnerabilities can easily eliminate application defenses, leading to a variety of attacks. No matter how many layers of validation data goes through, it should always be escaped/encoded for the right context. This concept is not only relevant for Cross-Site Scripting (XSS) vulnerabilities and the different HTML contexts, it also applies to any context where data and control planes are mixed.
The OWASP Developer Guide is a community effort and this page needs some content to be added. If you have suggestions then submit an issue and the project team can assign https://remotemode.net/become-a-net-razor-developer/owasp-proactive-controls/ it to you,
or provide new content direct on GitHub. Snyk interviewed 20+ security leaders who have successfully and unsuccessfully built security champions programs.
Upcoming OWASP Global Events
This includes making sure no sensitive data, such as passwords, access tokens, or any Personally Identifiable Information (PII) is leaked into error messages or logs. It’s important to carefully design how your users are going to prove their identity and how you’re going to handle user passwords and tokens. This should include processes and assumptions around resetting or restoring access for lost passwords, tokens, etc. In this post, you’ll learn how using standard and trusted libraries with secure defaults will greatly help you implement secure authentication.
- Database injections are probably one of the best-known security vulnerabilities, and many injection vulnerabilities are reported every year.
- In this series, I’m going to introduce the OWASP Top 10 Proactive Controls one at a time to present concepts that will make your code more resilient and enable your code to defend itself against would-be attackers.
- It lists security requirements such as authentication protocols, session management, and cryptographic security standards.
- The OWASP Top Ten Proactive Controls 2018 is a list of security techniques that should be considered for every software development project.
- You’ll learn about the OWASP ASVS project, which contains hundreds of already classified security requirements that will help you identify and set the security requirements for your own project.
Other examples that require escaping data are operating system (OS) command injection, where a component may execute system commands that originate from user input, and hence carry the risk of malicious commands being executed. Interested in reading more about SQL injection attacks and why it is a security risk? Our presence deterred crime, made letter carriers feel safe, and effected arrests. Our officers were often first responders and canvassed neighborhoods for witnesses when carriers were assaulted, robbed and shot. Use the extensive project presentation that expands on the information in the document.
Entirely new vulnerability categories such as XS Leaks will probably never make it to these lists, but that doesn’t mean you shouldn’t care about them. For any of these decisions, you have the ability to roll your own–managing your own registration of users and keeping track of their passwords or means of authentication. As an alternative, you can choose to managed services and benefit from the cloud’s Serverless architecture of services like Auth0. This category was previously called “Insufficient Logging & Monitoring”. When weakly applied, attackers can stay under the radar for months and cause enormous amounts of damage.
OWASP Top 10 Proactive Controls describes the most important control and control categories that every architect and developer should absolutely, 100% include in every project. The Top 10 Proactive Controls are by developers for developers to assist those new to secure development. However, development managers, product owners, Q/A professionals, program managers, and anyone involved in building software can also benefit from this document. It is impractical to track and tag whether a string in a database was tainted or not.
Most importantly, the ASVS provides a phased approach to gradually implement security requirements as you are making your first steps. An easy way to secure applications would be to not accept inputs from users or other external sources. Checking and constraining those inputs against the expectations for those inputs will greatly reduce the potential for vulnerabilities in your application. As software becomes the foundation of our digital—and sometimes even physical—lives, software security is increasingly important. But developers have a lot on their plates and asking them to become familiar with every single vulnerability category under the sun isn’t always feasible. Even for security practitioners, it’s overwhelming to keep up with every new vulnerability, attack vector, technique, and mitigation bypass.
Developers are already wielding new languages and libraries at the speed of DevOps, agility, and CI/CD. The list goes on from injection attacks protection to authentication, secure cryptographic APIs, storing sensitive data, and so on. Once authentication is taken care of, authorization should be applied to make sure that authenticated users have the permissions to perform any actions they need but nothing beyond those actions is allowed. In this post, you’ll learn more about the different types of access control and the main pitfalls to avoid.
