Write more secure code with the OWASP Top 10 Proactive Controls

The ASVS can be used to provide a framework for an initial checklist, according to the security verification level,
and the initial ASVS checklist can then be expanded using the following checklist sections. A user story focuses on the perspective of the user, administrator, or attacker of the system, and describes functionality based on what a user wants the system to do for them. Failure to enforce least privileges in an application can jeopardize the confidentiality of sensitive resources. Mitigation strategies are applied primarily during the Architecture and Design phase (see CWE-272); however, the principle must be addressed throughout the SDLC. When an application encounters an error, exception handling will determine how the app reacts to it. Proper handling of exceptions and errors is critical to making code reliable and secure.

Most importantly, the ASVS provides a phased approach to gradually implement security requirements as you are making your first steps. 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. A security requirement is a statement of security functionality that ensures software security is being satisfied. Security requirements are derived from industry standards, applicable laws, and a history of past vulnerabilities. The process includes discovering / selecting, documenting, implementing, and then confirming correct implementation of new security features and functionality within an application.

Implement Appropriate Logging¶

These include things such as injection, broken authentication and access control, security misconfigurations, and components with known vulnerabilities. But the list doesn’t offer the kind of defensive techniques and controls useful to developers trying to write secure code. 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.

  • In addition, serious cryptography research is typically based in advanced mathematics and number theory, providing a serious barrier to entry.
  • On Android this will be the Android keystore and on iOS this will be the iOS keychain.
  • Credit card numbers may be classified as private user data which may need to be encrypted while stored or in transit.
  • It is impractical to track and tag whether a string in a database was tainted or not.
  • 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.
  • These include things such as injection, broken authentication and access control, security misconfigurations, and components with known vulnerabilities.
  • For example, the OWASP Top 10, a cornerstone of web application security, identifies the risks of the most common vulnerabilities in applications.

For example, public marketing information that is not sensitive may be categorized as public data which is ok to place on the public website. Credit card numbers may be classified as private user data which may need to be encrypted while stored or in transit. Just as you’d often leverage the typing system, like TypeScript, to ensure expected and valid variables are passed around your code, you should also be validating the input you received https://remotemode.net/ matches your expectations or models of that data. This lesser-known OWASP project aims to help developers prevent vulnerabilities from being introduced in the first place. Authentication is the process of verifying that an individual or entity is who they claim to be. Session management is a process by which a server maintains the state of the users authentication
so that the user may continue to use the system without re-authenticating.

Put OWASP Top 10 Proactive Controls to work

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. This requirement contains both an action to verify that no default passwords exist, and also carries with it the guidance that no default passwords should be used within the application. Flaws related to authorization logic owasp top 10 proactive controls are a notable concern for web apps. Broken Access Control was ranked as the most concerning web security vulnerability in OWASP’s 2021 Top 10 and asserted to have a “High” likelihood of exploit by MITRE’s CWE program. 10, Access Control was among the more common of OWASP’s Top 10 risks to be involved in exploits and security incidents despite being among the least prevalent of those examined.

Details of errors and exceptions are useful to us for debugging, analysis, and forensic investigations. They are generally not useful to a user unless that user is attacking your application. In this blog post, you’ll learn more about handling errors in a way that is useful to you and not to attackers. 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. 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.

Application Secrets Management¶

Cross-site Scripting (XSS) vulnerabilities are an excellent example of how data may flow through the system and end up employing malicious code in a browser context, such as JavaScript, that get evaluated and compromises the browser. Databases are often key components for building rich web applications as the need for state and persistency arises. This list was originally created by the current project leads with contributions from several volunteers. The document was then shared globally so even anonymous suggestions could be considered. You need to protect data whether it is in transit (over the network) or at rest (in storage).

Also, an attacker could use SQL Injection to steal passwords and other credentials from an applications database and expose that information to the public. Access Control design may start simple but can often grow into a complex and feature-heavy security control. 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.

Before an application accepts any data, it should determine whether that data is syntactically and semantically valid in order to ensure that only properly formatted data enters any software system component. For example, each component such as application libraries and operating system libraries in docker images can be tested for known vulnerabilities. Input validation is a programming technique that ensures only properly formatted data may enter a software system component.
