1 The OWASP Way Understanding the OWASP Vision and the Top Ten

2 About Me Software Security Engineer for TD Ameritrade – All information presented today is exclusively my own and does not necessarily reflect the views or position of my employer. Any questions or concerns regarding material presented today should be addressed to the OWASP Board of Directors care of Sarah Baso. Geek Card

3 What the Heck is OWASP? – The Open Web Application Security Project (OWASP) is a 501(c)(3) worldwide not-for-profit charitable organization focused on improving the security of software. Our mission is to make software security visible, so that individuals and organizations worldwide can make informed decisions about true software security risks. – Everyone is free to participate in OWASP and all of our materials are available under a free and open software license. You'll find everything about OWASP here on or linked from our wiki and current information on our OWASP Blog. OWASP does not endorse or recommend commercial products or services, allowing our community to remain vendor neutral with the collective wisdom of the best minds in software security worldwide. We ask that the community look out for inappropriate uses of the OWASP brand including use of our name, logos, project names and other trademark issues. – There are thousands of active wiki users around the globe who review the changes to the site to help ensure quality. If you're new, you may want to check out our getting started page. As a global group of volunteers with over 36,000 participants, questions or comments should be sent to one of our many mailing lists or directed to the OWASP Contact Us Form.

4 Too Many Words AAAhhhhhhh !!!!!!!!


6 GoodBye Slides

7 GoodBye Slides Geek Style Did I mention I had a Geek Card?

8 So OWASP is WHAT Really ?

9 2 Parts

10 OWASP Security Awareness Training/Standards/Guidelines for Secure Software Development in the Web Application/Mobile Application Space Projects! INFORMATION



13 So What is it you would say you OWASP guys do here?

14 We help the community Exterminate Bugs

15 Not like This Guy

16 We like to think we are this guy

17 But we are probably closer to this guy

18 software We help people fix security related software bugs


20 What we see A random kid with family issues, who just happens to come across attack plans his buddies found on the internet, and takes down the whole system with one lucky shot


22 So, how do we help? By Looking For Stuff Like This


24 A1 - INJECTION What is it? Injection flaws, such as SQL, OS, and LDAP injection occur when untrusted data is sent to an interpreter as part of a command or query. The attacker’s hostile data can trick the interpreter into executing unintended commands or accessing data without proper authorization.

25 A1 - INJECTION - Continued Parameterized Queries the variable data in the SQL statement is replaced with a placeholder such as a question mark, which indicates to the database engine that this is aparameter Becomes the Database drivers responsibility (think compiled code) Traditional SQL Statement Execute Retrieve Results Parameterized Model Parse the statement (often called preparing the statement.) Bind the parameter values to the parameters. Execute the statement. Optionally, retrieve the results Close or finalize the statement.

26 A2 - Broken Authentication and Session Management What is it? Application functions related to authentication and session management are often not implemented correctly, allowing attackers to compromise passwords, keys, or session tokens, or to exploit other implementation flaws to assume other users’ identities.

27 A2 - Broken Authentication and Session Management - Continued

28 A3 - Cross-Site Scripting (XSS) What is it? XSS flaws occur whenever an application takes untrusted data and sends it to a web browser without proper validation or escaping. XSS allows attackers to execute scripts in the victim’s browser which can hijack user sessions, deface web sites, or redirect the user to malicious sites.

29 A3 - Cross-Site Scripting (XSS) - Continued

30 A4 - Insecure Direct Object References What is it? A direct object reference occurs when a developer exposes a reference to an internal implementation object, such as a file, directory, or database key. Without an access control check or other protection, attackers can manipulate these references to access unauthorized data.

31 A4 - Insecure Direct Object References - Continued

32 A5 - Security Misconfiguration What is it? Good security requires having a secure configuration defined and deployed for the application, frameworks, application server, web server, database server, and platform. Secure settings should be defined, implemented, and maintained, as defaults are often insecure. Additionally, software should be kept up to date.

33 A5 - Security Misconfiguration - Continued

34 A6 - Sensitive Data Exposure What is it? Many web applications do not properly protect sensitive data, such as credit cards, tax IDs, and authentication credentials. Attackers may steal or modify such weakly protected data to conduct credit card fraud, identity theft, or other crimes. Sensitive data deserves extra protection such as encryption at rest or in transit, as well as special precautions when exchanged with the browser.

35 A6 - Sensitive Data Exposure - Continued

36 A7 - Missing Function Level Access Control What is it? Most web applications verify function level access rights before making that functionality visible in the UI. However, applications need to perform the same access control checks on the server when each function is accessed. If requests are not verified, attackers will be able to forge requests in order to access functionality without proper authorization.

37 A7 - Missing Function Level Access Control - Continued

38 A8 - Cross-Site Request Forgery (CSRF) What is it? A CSRF attack forces a logged-on victim’s browser to send a forged HTTP request, including the victim’s session cookie and any other automatically included authentication information, to a vulnerable web application. This allows the attacker to force the victim’s browser to generate requests the vulnerable application thinks are legitimate requests from the victim.

39 A8 - Cross-Site Request Forgery (CSRF) - Continued

40 A9 - Using Components with Known Vulnerabilities What is it? Components, such as libraries, frameworks, and other software modules, almost always run with full privileges. If a vulnerable component is exploited, such an attack can facilitate serious data loss or server takeover. Applications using components with known vulnerabilities may undermine application defenses and enable a range of possible attacks and impacts.

41 A9 - Using Components with Known Vulnerabilities - Continued

42 A10 - Unvalidated Redirects and Forwards What is it? Web applications frequently redirect and forward users to other pages and websites, and use untrusted data to determine the destination pages. Without proper validation, attackers can redirect victims to phishing or malware sites, or use forwards to access unauthorized pages.

43 A10 - Unvalidated Redirects and Forwards - Continued

44 What’s Next for Developers????????

45 A Marathon Not A Sprint
