Exploring OWASP Top Ten

This is an introductory-level course designed for technical stakeholders and web developers.  Familiarity with programming is helpful but not required. 

After a quick examination of the context for application security and the OWASP Top 10, each of the vulnerabilties are covered in detail. After the ten vulnerabilities are examined in detail, we wrap up with sessions on next steps for attendees to take as well as an overview of Threat Modeling. 

Attendees will gain an understanding of:

• The mechanism by which the vulnerability is exploited. Often the exploitability of a vulnerability is rooted in an underlying pattern that is valid across many technologies and architectures.
• The prevalence of the vulnerability, including characteristics to focus on during design and code reviews to help detect potential issues.
• The potential consequences of a successful exploit.
• The measures that can be taken to eliminate, prevent, or minimize the risk of an exploited vulnerability.
• The relative effectiveness of scanners and other tools in detecting the vulnerability being discussed.
• Generic and code-specific references that can be utilized after the session.
