This approach is suitable for adoption by all developers, even those who are new to software security. Each of these examples illustrates the importance of proper authorization in web applications to protect resources from unauthorized access. Always ensure that both the backend and frontend enforce access controls correctly. Regular audits and security tests are also vital to maintain a secure application.
- Broken Access Control is when an application does not correctly implement a policy that controls what objects a given subject can access within the application.
- However, this document should be seen as a starting point rather than a comprehensive set of techniques and practices.
- The Proactive Controls list starts by defining security requirements derived from industry standards, applicable laws, and a history of past vulnerabilities.
- This requires collaboration across departments to solidify a shared understanding of these imperatives.
- 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.
Instead, you build proper controls in the presentation layer, such as the browser, to escape any data provided to it. Security misconfiguration is when an important step to secure an application or system is skipped intentionally or forgotten. However, development managers, product owners, Q/A professionals, program managers, and anyone involved in building software can also benefit from this document. All access control failures should be logged as these may be indicative of a malicious user probing the application for vulnerabilities. Access Control (or Authorization) is the process of granting or denying specific requests from a user, program, or process. Access control also involves the act of granting and revoking those privileges.
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 OWASP Top Ten Proactive Controls 2018 is a list of security techniques that should be included in every software development project. This document’s main purpose is to provide a solid foundation of topics to help drive introductory software security developer training.
One example of a failure involves using untrusted software in a build pipeline to generate a software release. Another example is insecure deserialization, where an application receives an object from another entity and does not properly validate that object, resulting in an attack being loosed upon the application that received the object. The Top Ten calls for more threat modeling, secure design patterns, and reference architectures. Threat modeling analyzes a system representation to mitigate security and privacy issues early in the life cycle.
- Access Control (or Authorization) is allowing or denying specific requests from a user, program, or process.
- Also known as separation of privilege, separation of duties is a security principle which requires thatthe successful completion of a single taskis dependent upon two or more conditions that are insufficient, individually by themselves, for completing the task.
- Vertical privilege escalation happens when a user gains access to a higher level of functionality that should be restricted.
- Automating IAM processes improves security and operational efficiency, ensuring only authorized users have access based on stringent, dynamic policies.

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. In this post, Senior Application Security Engineer Jason White will show you how to identify the characters with special meaning for any given context and how to properly encode them so they cannot be used to break out of the context they’re being written to. First, security vulnerabilities continue to evolve and a top 10 list simply owasp proactive controls can’t offer a comprehensive understanding of all the problems that can affect your software. 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. This cheat sheet will help users of the OWASP Top Ten Proactive Controls 2018 identify which cheat sheets map to each proactive control. The OWASP Top 10 Proactive Controls describes the most important controls and control categoriesthat security architects and development teams should consider in web application projects.
Some applications enforce access control at the platform level by restricting certain URLs or HTTP methods based on user roles. Context-dependent access controls adapt based on application state or user interactions, ensuring actions occur in the correct sequence. This prevents the scenario where you have multiple access control implementations, where most are correct, but some are flawed.
Let’s explore each of the OWASP Top Ten, discussing how the pieces of the Proactive Controls mitigate the defined application security risk. In this blog post, we’ll describe some common CORS issues as well as how you can find and fix them. You need to protect data whether it is in transit (over the network) or at rest (in storage).
C9: Implement Security Logging and Monitoring
When evaluating access control capability of software frameworks, ensure that your access control functionality will allow for customization for your specific access control feature need. 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. Broken Access Control is one of the most common web application vulnerabilities listed in the OWASP Top 10. It occurs when a user can perform actions and access resources that they are not authorized to access, often due to insufficient enforcement of access control policies. Attribute or feature-based access control checks of this nature are the starting point to building well-designed and feature-rich access control systems.
Objective¶
The OWASP Top 10 Proactive Controls is similar to the OWASP Top 10 but is focused on defensive techniques and controls as opposed to risks. Each technique or control in this document will map to one or more items in the risk based OWASP Top 10. Their idea is to prevent common vulnerabilities during an application’s inception so that those tedious and embarrassing bug fixes can be avoided altogether. Common knowledge is that a proactive approach will save resources and money in the long run.
SQL Injection Cheat Sheet
Proactive Controls is a catalog of available security controls that counter one or many of the top ten. 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.
The proactive controls document, written by Manico himself, along with Katy Anton and Jim Bird, provides a security overview for developers wanting to jump into web security, understand the different layers of security risks, and how to protect against them. 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. One of the main goals of this document is to provide concrete practical guidance that helps developers build secure software. The OWASP Top Ten Proactive Controls 2018 is a list of security techniques that should be considered for every software development project.
How to Use this Document¶
To be effective, these controls should be used consistently and thoroughly throughout all applications. As cyber threats grow in sophistication, CISOs must navigate an increasingly complex landscape of risks and vulnerabilities. With expanding regulatory requirements and the continuous evolution of attack methods, maintaining a robust cybersecurity posture is more critical than ever. By predefining, accounting for, and documenting these assets, CISOs can craft effective business continuity and disaster recovery plans before a major incident occurs. Horizontal access controls regulate access to data and resources among users of the same role or level. The security principle of least common mechanisms disallows the sharing of mechanisms that are commonto more than one user or process if the users or processes are at different levels of privilege.This is important when defending against privilege escalation.
Principle of Least Privilege / Just in Time (JIT), Just Enough Access (JEA)
When software is architected using the open design concept,the review of the design itself will not result in the compromise of the safeguards in the software. Also known as ‚keep it simple‘, if there are multiple implementations then the simplestand most easily understood implementation should be chosen. Make sure you track the use of open source libraries 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.
