Financial data and personal information like SSN are some of the most important details a person is concerned with, so an application storing that data should make sure it is encrypted securely. Broken Session Management is also a type of vulnerability which exists in a web application that does not properly implement session management. For example, if a user logs out from his/her account, but he/she is redirected to some page, but session is not invalidated properly, a post-login page is opened without asking for re-authentication. Another example can be a session cookie for pre- and post-login being same. Input validation can be implemented in a web application using regular expressions. A regular expression is an object that describes a pattern of characters.

Upcoming OWASP Global Events

OWASP ProActive Controls is a document prepared for developers who are developing or are new to developing software/application with secure software development. This OWASP project lists 10 controls that can help a developer implement secure coding and better security inside the application while it is being developed. Following these secure application development controls ensures that the key areas of the development cycle have secure coding along with traditional coding practices. But it is a known fact that industry tested security features are not readily available in programming languages. In such a case where useful and required security features or libraries are not available in the programming language you are using, then industry trusted and tested security libraries should be used.

  • In the end, you walk away with a set of practical guidelines to build more secure software.
  • It is better to use industry tested regular expressions than writing one on your own (which in most cases will be flawed).
  • They are ordered by order of importance, with control number 1 being the most important.

But older web server software like Apache or Struts can lead to an attacker successfully exploiting it and managing his/her way into the application and user data. In this part of OWASP ProActive Controls, we discussed in depth how ProActive Controls 1-5 can be used in an application as a secure coding practice to safeguard it from well-known attacks. The controls discussed do not modify application development lifecycle, but ensure that application security is given the same priority as other tasks and can be carried out easily by developers. One of the most important ways to build a secure web application is to restrict what type of input a user is allowed to submit. Input validation means validating what type of input is acceptable and what is not. Input validation is important because it restricts the user to submit data in a particular format only, no other format is acceptable.

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

OWASP ProActive Controls recommends that developers should use parameterized queries only in combination with input validation when dealing with database operations. In this session, Jim walked us through the list of OWASP Top 10 proactive controls and how to incorporate them into our web applications. If the database is compromised at the same time, the attacker will be able to access the user account easily. OWASP Proactive Controls Lessons The attacker will be able to login to the user’s account using the username and password from the database, which is stored in plain text. Depending upon the programming language a developer uses to build an application, regular expression can easily be implemented in it. Another advantage of regular expressions is that there are many industry tested regular expressions for all popular input types.

But she cannot open Bob’s family safe at home, because she is not authorized to do so. On the other hand, Bob’s sister Eve is known, so successful authentication occurs, and she is a family member, so she is authorized to access the family safe, aka successful authorization. In Reflected XSS, the XSS script does not get stored on the server but can be executed by the browser.

Developer Guide (draft)

Since all user activity is being logged, it should also be noted that user sensitive data like password and financial details should NEVER be logged. Asymmetric method or Public Key Cryptography (PKC) uses two sets of keys to perform encryption and decryption. Public Key is used for data encryption and Private Key is used for data decryption.

As an alternative, you can choose to managed services and benefit from the cloud’s Serverless architecture of services like Auth0. Authorization is the process of giving someone permission to do or have something. It is to be noted again that authentication is not equivalent to authorization. Here this expression shows that username should include alphabets ‘a-z’, numbers ‘0-9’ and special characters underscore ‘_’ only. Blacklisting is invalidating an input by looking for specific things only. For example, specifying that a phone number should be of 10 digits with only numbers is whitelist.

The Top 10 Proactive Controls

This cheatsheet will help users of the OWASP Proactive Controls identify which cheatsheets map to each proactive controls item. Authentication takes care of your identity, whereas authorization makes sure that you have the authority or privilege to access a resource like data or some sensitive information. OWASP has an Input Validation Cheat Sheet to help you implement proper input validation in your application. Databases are often key components for building rich web applications as the need for state and persistency arises. Building a secure product begins with defining what are the security requirements we need to take into account. Just as business requirements help us shape the product, security requirements help us take into account security from the get-go.
