Web Application Security
Why Web Application Security?
There is no doubt that every business is integrating web applications or already done so to allow employees and customers to interact on daily basis. This can be an employee who is checking his or her emails or a customer placing an order thru a shopping cart application. The first problem is that we cannot distinguish between a normal user and a criminal one. The second problem, applications are written by humans therefore are susceptible to bugs and errors.
The Threats
Most of the threats are errors while coding the application and wrong assumptions by the programmer how his application will be executed within the browser. Other threats are relay on patch management or system misconfiguration. As a reference we are using the Top 10 threats that were defined by the OWASP organization for 2010-2013:
Year 2010 Top 10
A1: Injections
A2: Cross-Site Scripting (XSS)
A3: Broken Authentication and Session Management
A4: Insecure Direct Object References
A5: Cross-Site Request Forgery
A6: Security Misconfiguration
A7: Insecure Cryptographic Storage
A8: Failure to Restrict URL Access
A9: Insufficient Transport Layer Protection
A10: Unvalidated Redirects and Forwards
Year 2013 Top 10
A1 Injection
A2 Broken Authentication and Session Management
A3 Cross-Site Scripting (XSS)
A4 Insecure Direct Object References
A5 Security Misconfiguration
A6 Sensitive Data Exposure
A7 Missing Function Level Access Control
A8 Cross-Site Request Forgery (CSRF)
A9 Using Components with Known Vulnerabilities
A10 Unvalidated Redirects and Forwards
The Top 10 is good for companies to get started with Web Application security and you should not stop there is threats landscape is changing constantly – so your security.
The Solution
2Secure has developed a solution that has three stages that can help and mitigate the threats:
- Preform risk assessments BEFORE & AFTER web application is in production
- Based on the results from the risk assessment, implement mitigating controls.
- Integrate safeguards during the Software Development Life Cycle (SDLC) BEFORE the application is published on the Internet or Intranet.
