OWASP Top Ten Proactive Controls 2018 C1: Define Security Requirements OWASP Foundation


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. OWASP Top 10 Proactive Controls describes owasp proactive controls 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.

  • Combining input validation with data encoding can solve many problems of malicious input and safeguard the application and its users from attackers.
  • This cheatsheet will help users of the OWASP Proactive Controls identify which cheatsheets map to each proactive controls item.
  • A risky crypto algorithm may be one that was created years ago, and the speed of modern computing has caught up with the algorithm, making it possible to be broken using modern computing power.
  • Applications contain numerous “secrets” that are needed for security operations.
  • Most importantly, the ASVS provides a phased approach to gradually implement security requirements as you are making your first steps.

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. 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.

How to Use this Document¶

Other key modules like forgot password and change password are also part of authentication. 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. For example, if you want to access your bank account details or perform a transaction, you need to login into your bank account website. Successfully authenticating to your bank account proves that you are the owner of that account. From this discussion, it is clear that username and password are the elements of authentication that prove your identity.

Her identity is known to Bob, so he allows her to enter her home (if she was not known to Bob then entry would have been denied, aka authentication failure). 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. These attacks are delivered to victims via common communication mediums like e-mail or some other public website.

Project Information

Credit card numbers may be classified as private user data which may need to be encrypted while stored or in transit. Many developers have a tough time handling authorization, and at some point leave a gap that gets exploited, leading to unauthorized data access. OWASP has an Input Validation Cheat Sheet to help you implement proper input validation in your application. As application developers, we are used to logging data that helps us debug and trace issues concerning wrong business flows or exceptions thrown. Security-focused logging is another type of data logs that we should strive to maintain in order to create an audit trail that later helps track down security breaches and other security issues.

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. In this vulnerable code, the ‘Statement’ class is used to create a SQL statement, and at the same time it is modified by directly adding user input to it, then it is executed to fetch results from the database. Performing a simple SQLi attack in the username field will manipulate the SQL query, and an authentication bypass can take place. The answer is with security controls such as authentication, identity proofing, session management, and so on. A prominent OWASP project named Application Security Verification Standard—often referred to as OWASP ASVS for short—provides over two-hundred different requirements for building secure web application software. 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.

The OWASP Top 10 Proactive Controls: a more practical list

An injection is when input not validated properly is sent to a command interpreter. 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.

  • If you devote your free time to developing and maintaining OSS projects, you might not have the time, resources, or security knowledge to implement security features in a robust, complete way.
  • From this discussion, it is clear that username and password are the elements of authentication that prove your identity.
  • Some part of the application fetches that information from the database and sends it to the user without properly encoding it.
  • It is better to use industry tested regular expressions than writing one on your own (which in most cases will be flawed).

In addition, serious cryptography research is typically based in advanced mathematics and number theory, providing a serious barrier to entry. This patched code will invalidate the session when authentication is successful and creates a new session cookie value. This changes the post-login session cookie value, and Session Fixation vulnerability cannot be exploited.

A graduate in computer science, she has experience in secure coding, application development and researching the security side of application development. Implementing authorization is one of the key components of application development. It has to be ensured at all times that access certain parts of the application should be accessible to users with certain privileges only. Stored XSS are those XSS which get stored on a sever like in a SQL database. Some part of the application fetches that information from the database and sends it to the user without properly encoding it. It then leads to malicious code being executed by the browser on the client side.
