Developing secure software: how to implement the OWASP top 10 Proactive Controls

The input is interpreted as a command, processed, and performs an action at the attacker’s control. The injection-style attacks come in many flavors, from the most popular SQL injection to command, LDAP, and ORM. Attribute or feature-based access control checks of this nature are the starting point to building well-designed and feature-rich access control systems. This type of programming also allows for greater access control customization capability over time. Ensure that all users, programs, or processes are only given as least or as little necessary access as possible. Be wary of systems that do not provide granular access control configuration capabilities.

  • A subject is an individual, process, or device that causes information to flow among objects or change the system state.
  • The answer is with security controls such as authentication, identity proofing, session management, and so on.
  • You may even be tempted to come up with your own solution instead of handling those sharp edges.
  • 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.
  • While the current OWASP Proactive Controls do not match up perfectly with the OWASP Top Ten for 2021, they do a fair job of advising on controls to add to your applications to mitigate the dangers the Top Ten describes.
  • In this session, Jim walked us through the list of OWASP Top 10 proactive controls and how to incorporate them into our web applications.

However, this document should be seen as a starting point rather than a comprehensive set of techniques and practices. The Open Web Application Security Project (OWASP) is an organization that solely specializes in the knowledge of software security. OWASP uses their knowledge to create lists for top risks and proactive controls, application security standards, and prevention cheat sheets for remediating specific risks. The OWASP Top 10 Most Critical Web Application Security Risks is continuously updated to showcase the most critical application security risks. The risks are always used as a baseline to test against when conducting any vulnerability or penetration tests. On the other hand, the OWASP Top 10 Proactive Controls was created to assist in developing an application that is not vulnerable to any of the top risks identified.

  • Two great examples of secure defaults in most web frameworks are web views that encode output by default (providing XSS attack defenses) as well as built-in protection against Cross-Site Request Forgeries.
  • The Open Web Application Security Project (OWASP) is an organization that solely specializes in the knowledge of software security.
  • This cheatsheet will help users of the OWASP Proactive Controls identify which cheatsheets map to each proactive controls item.
  • 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.
  • However, this document should be seen as a starting point rather than a comprehensive set of techniques and practices.

Monitoring is reviewing security events generated by a system to detect if an attack has occurred or is currently occurring. Note that X-Xss-Protection is questionable since it adds client-side XSS filters that have proven to be complicated in the past to the point of them being near useless or even used to enable other attacks. I would suggest not enabling this header and to rely on the server-side, context-aware, content-encoding instead.

A01 Broken Access Control

Encapsulate those libraries in your own classes, and use static analysis to find violations of your security requirement invariants. Many application frameworks default to access control that is role based. It is common to find application code that is filled with checks of this nature. Access Control design may start simple but can often grow into a complex and feature-heavy security control.

Just as business requirements help us shape the product, security requirements help us take into account security from the get-go. Handling errors and exceptions properly ensures no backend information is disclosed to any attackers. For example, an SQL exception will disclose where in the SQL query the maliciously crafted input is and which type of database is being used. As vulnerabilities are discovered in them, you need to ensure continuous updates are applied to them to reduce exposure. While the current OWASP Proactive Controls do not match up perfectly with the OWASP Top Ten for 2021, they do a fair job of advising on controls to add to your applications to mitigate the dangers the Top Ten describes. Logging is storing a protected audit trail that allows an operator to reconstruct the actions of any subject or object that performs an action or has an action performed against it.
