Short Answer Questions

Question 1: Briefly describe the web technology stack used in your implementation.

Answer: Our tech stacks consists of:

• Backend: NoSQL database (MongoDB)
• Server: Node.js with Express framework and Mongoose wrapper for MongoDB
• Front-end: HTML, CSS, JavaScript, jQuery, Bootstrap4

Question 2: Are there any security considerations your team thought about?

Answer: We considered the following security measures (have not implemented them):

• XSS defenses by input/output sanitization and escaping.
• CSRF defenses by using tokens and checking origin header.
• Implementing CSP to prevent general injection attacks.
• Password requirements (length, special characters, etc)

We have implemented the following:

• NoSQL injection defenses (implemented by using Mongoose prepared statements).

Question 3: Are there any improvements you would make to the API specification to improve the security of the web application?

Answer: Since the token is sent in cleartext, session hijacking can take place.

Question 4: Are there any additional features you would like to highlight?

Answer: We have implemented the following features:

• Password security: Using a combination of hashing and salts.
• We implemented a whitelist such that only http://localhost:80 can make requests to the API.

Question 5: Is your web application vulnerable? If yes, how and why? If not, what measures did you take to secure it?

Answer: Yes, the web application is vulnerable to the following types of attacks:

• XSS: inputs and outputs are not sanitized, html and urls are not escaped.
• CSP: No implementation of CSP directives allows for injection of malicious scripts.
• Lack of auto expiry of auth token can leave the app vulnerable if an attacker gains access - CSRF.
• Unencrypted traffic - opens the gate for MiTM attacks.

Feedback: Is there any other feedback you would like to give?

Answer: There are inconsistencies with the API documentation. /diary/delete should be implemented using DELETE verb and /diary/permission should be implemented using PUT.

Appreciate the flexibility in choosing our own tech stack, however with lack of experience in Docker, it has been quite difficult.
