Write more secure code with the OWASP Top 10 Proactive Controls

This document is intended to provide initial awareness around building secure software. This document will also provide a good foundation of topics to help drive introductory software security developer training. These controls should be used consistently and thoroughly throughout all applications. However, this document should be seen as a starting point rather than a comprehensive set of techniques and practices.

  • An application could have vulnerable and outdated components due to a lack of updating dependencies.
  • This mapping information is included at the end of each control description.
  • Many future vulnerabilities can be prevented by thinking about and designing for security earlier in the software development life cycle (SDLC).

Secure design patterns and reference architectures provide a positive, secure pattern that developers can use to build new features. Many future vulnerabilities can be prevented by thinking about and designing for security earlier in the software development life cycle (SDLC). 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.

Enforce Access Controls¶

These include certificates, SQL connection passwords, third party service account credentials, passwords, SSH keys, encryption keys and more. The unauthorized disclosure or modification of these secrets could lead to complete system compromise. As a general rule, only the minimum data required should be stored on the mobile device. But if you must store sensitive data on a mobile device, then sensitive data should be stored within each mobile operating systems specific data storage directory. On Android this will be the Android keystore and on iOS this will be the iOS keychain.

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.

Application Secrets Management¶

Sometimes though, secure defaults can be bypassed by developers on purpose. 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. Just as functional requirements are the basis of any project and something we need to do before writing the first line of code, security requirements are the foundation of any secure software. In the first https://remotemode.net/become-a-net-mvc-developer/owasp-proactive-controls/ blog post of this series, I’ll show you how to set the stage by clearly defining the security requirements and standards of your application. 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. This approach is suitable for adoption by all developers, even those who are new to software security.

  • 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.
  • This story contains the same message as the traditional requirement from ASVS, with additional user or attacker details to help make the requirement more testable.
  • From the “Authentication Verification Requirements” section of ASVS 3.0.1, requirement 2.19 focuses on default passwords.

This story contains the same message as the traditional requirement from ASVS, with additional user or attacker details to help make the requirement more testable. Your profile’s README invites the world to know you and your work, so it’s important that everyone can read and understand it. Discover tips, technical guides, and best practices in our monthly newsletter for developers. Use the extensive project presentation that expands on the information in the document.

Define Security Requirements¶

There are several different types of access control design that should be considered. A security requirement is a statement of needed security functionality that ensures one of many different security properties of software is being satisfied. Security requirements are derived from industry standards, applicable laws, and a history of past vulnerabilities. Security requirements define new features or additions to existing features to solve a specific security problem or eliminate a potential vulnerability.

  • This document was written by developers for developers to assist those new to secure development.
  • There is no specific mapping from the Proactive Controls for Insecure Design.
  • With a default password, if attackers learn of the password, they are able to access all running instances of the application.
  • When transmitting sensitive data over any network, end-to-end communications security (or encryption-in-transit) of some kind should be considered.

This issue manifests as a lack of MFA, allowing brute force-style attacks, exposing session identifiers, and allowing weak or default passwords. An application could have vulnerable and outdated components due to a lack of updating dependencies. A component, in this case, was added at some point in the past, and the developers do not have a mechanism to check for security problems and update their software components.

A01 Broken Access Control

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. Software and data integrity failures include issues that do not protect against integrity failures in software creation and runtime data exchange between entities. One example of a failure involves using untrusted software in a build pipeline to generate a software release. Cryptographic failures are breakdowns in the use of cryptography within an application, stemming from the use of broken or risky crypto algorithms, hard-coded (default) passwords, or insufficient entropy (randomness). A broken or risky crypto algorithm is one that has a coding flaw within the implementation of the algorithm that weakens the resulting encryption.

The advantage of a user story or misuse case is that it ties the application to exactly what the user or attacker does to the system, versus describing what the system offers to the user. 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.
