You Will Learn How To
- Implement and test secure Web applications in your organisation
- Identify, diagnose and correct the most serious Web application vulnerabilities
- Configure a Web server to encrypt Web traffic with HTTPS
- Protect Ajax-powered Web 2.0 applications
- Secure XML Web services with WS-Security
- Audit Web application security with manual and automated scanning
Course Benefits
Cybersecurity is a serious challenge today as attackers specifically target Web application vulnerabilities. These vulnerabilities can be exploited to obtain confidential information and compromise organisational integrity. As a result, organisations must integrate robust security measures into the Web application development process. This course provides in-depth, hands-on experience securing Web-based applications and host servers.
Who Should Attend
Those who want to implement, test and deploy secure Web applications. Basic knowledge of Web application operation and Web server administration is assumed. Web application development and security knowledge are helpful but not required.
Hands-On Training
Throughout this course, extensive hands-on exercises based on an evolving case study provide you with practical experience in securing applications. Exercises include:
- Creating a trust boundary with proper input validation
- Avoiding cross-site scripting (XSS) and cross-site request forgery (CSRF/XSRF)
- Preventing SQL injection vulnerabilities
- Implementing URL access restrictions
- Detecting unauthorised file system modification
- Enabling HTTPS on a Web server
- Protecting Web services with WS-Security
- Identifying vulnerabilities with an application scanner
