Scanning uploaded files for malware

Providing detailed error messages for failed uploads

QUESTION 67
In the context of web applications, what role does the HTTP ‘GET’ method serve?
Response:

It submits data to be processed to a specified resource.

It requests a representation of the specified resource and should only retrieve data.

It replaces all current representations of the target resource with the request payload.

It requests that the server accept the entity enclosed in the request as a new subordinate of the web resource identified by the URI.

QUESTION 68
Which approach should be adopted to secure communication between web service components?
Response:

Implementing application-level encryption only for sensitive data fields

Using HTTPS for transport-level security in addition to application-level security mechanisms

Relying solely on network firewalls for intercepting malicious traffic

Encrypting only the SOAP header for efficiency and speed

QUESTION 69
What is a common risk associated with file uploads in web applications?
Response:

Slower page load times

Unauthorized execution of malicious files

Increased bandwidth usage

Inability to process large files

QUESTION 70
In the context of web application security, what is the purpose of tokenization?
Response:

To replace sensitive data with non-sensitive substitutes

To encrypt data using a token-based system

To facilitate user authentication

To validate data integrity

QUESTION 71
What is the primary function of cookies in web applications?
Response:

To serve targeted advertisements to users based on their browsing history.

To encrypt data transmissions between the user’s browser and the web server.

To store data on the client’s computer to facilitate persistent, stateful information between page requests.

To increase the computational performance of the server by offloading processing to the client.

QUESTION 72
In the context of file uploads, what are two critical security checks to implement?
(Choose Two)
Response:

Verifying the file extension only

Checking the file MIME type against a whitelist

Ensuring the uploaded file is not executable on the server

Allowing all file types but scanning for size

QUESTION 73
Which testing method is effective for identifying security issues in session management?
Response:

Load testing to ensure the application can handle many simultaneous sessions.

Usability testing to confirm that session management is user-friendly.

Penetration testing focused on session management mechanisms.

A/B testing different session timeout values to find the most user-friendly option.
