A web development company is working on an e-commerce website
and wants to ensure that user-generated content, such as product
reviews, does not introduce security vulnerabilities. Therefore, they
follow secure coding best practices and implement output encoding to
mitigate potential risks. What outcome can the company expect from
correctly implementing output encoding?
A.Encoding special characters in user-generated content
B.Automatically validating user input before storing it in the database
C.Protecting the application against SQL injection attacks
D.Ensuring that user input is stored in a parameterized query
A.Encoding special characters in user-generated content
The correct approach is to prevent cross-site scripting (XSS) attacks by
encoding special characters in user-generated content. Output
encoding ensures that special characters in user-generated content are
safely encoded, preventing malicious scripts from executing by the
browser.
,Page 2 of 69
While input validation is important, output encoding specifically
addresses the secure handling of user-generated content when
displayed, not when stored.
Output encoding focuses on preventing cross-site scripting (XSS)
attacks, not structured query language (SQL) injection attacks.
Parameterized queries protect against SQL injection attacks.
Ensuring that the system stores user input in a parameterized query is
a technique for preventing SQL injection attacks, not an outcome of
output encoding.
An e-commerce platform has identified a stack overflow vulnerability
in one of its critical applications. The organization has tasked a
security analyst with suggesting effective controls to mitigate the risk
associated with this vulnerability. Considering the nature of the
vulnerability, which control should the analyst recommend?
A.Implementing input validation and sanitization
B.Enabling secure cookie flags
C.Applying Content Security Policy (CSP)
D.Employing Address Space Layout Randomization (ASLR)
D.Employing Address Space Layout Randomization (ASLR)
,Page 3 of 69
ASLR is a security technique that randomizes the memory address
locations where the system loads application code and data. This
randomization makes it more challenging for attackers to exploit stack
overflow vulnerabilities.
A software development company has already included planning,
implementation, testing, and maintenance stages in its software
development lifecycle (SDLC). Which of the following stages did the
company NOT include? (Select the two best options.)
A.Testing
B.Design
C.Deployment
D.Post-implementation review
B.Design
C.Deployment
A healthcare organization is developing a web-based patient records
system. During the testing phase, security analysts identified several
injection flaws that could potentially compromise sensitive patient
data. Which controls should the organization implement to mitigate
the risks associated with injection flaws?
A.Employ least privilege principles for database access
, Page 4 of 69
B.Implement parameterized queries and input validation
C.Use cookies to store user session data
D.Disable security headers in the application
B.Implement parameterized queries and input validation
A security analyst is examining an incident where an attacker
exploited a web application to gain unauthorized access to files and
resources on the server. The attacker manipulated user input to
include external files or traverse the server's directory structure.
Which of the following web vulnerabilities are most likely to be
responsible for this scenario? (Select the two best options.)
A.Server-Side Request Forgery (SSRF)
B.Cross-Site Request Forgery (CSRF)
C.Local File Inclusion (LFI)
D.Remote File Inclusion (RFI)
C.Local File Inclusion (LFI)
D.Remote File Inclusion (RFI)
Local File Inclusion (LFI) is a type of web vulnerability that allows an
attacker to include local files on the server, often resulting in
unauthorized access to sensitive files and resources.
