Correct Option: B

After 30 minutes your scan stops with an out-of-session error. What is a possible cause of this error?
technology security

  1. Redundant path limit was too low

  2. A parameter was not tracked

  3. Flash parsing was turned off

  4. Platform authentication was not configured

Show answer
Correct Option: B

AppScan sent the following test HTTP request: GET /web/content/index.php?file=/../../../../../../../../etc/passwd%00 HTTP/1.0 Cookie: JSESSIONID=dqt0LSnfhdVyTJkCwTwfLQQSkTTGYX9D79tLLpT1yLQjVhSpZKP9!914376523; customerLanguage=en Accept: / Accept-Language: en-US User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Win32) Host: www.ibm.com Although, there is no indication in the response about the existence of a password file, AppScan reported vulnerability with the following reasoning: Global Validation found an embedded script in the response (alert(25053)), which was probably injected by a previous test. The presence of this script in the site suggests that the application is vulnerable to which type of attack?

  4. Insecure communication

Show answer
Correct Option: C

Why is it important to encrypt the HTTP traffic for an authenticated connection between a client and a web server?
technology security

  1. to prevent SQL injection

  2. to prevent sensitive information from being stolen

  3. to prevent cross site scripting

  4. to prevent Web site defacement

Show answer
Correct Option: B

How can an attacker take advantage of the information gained from an SQL debug message?
technology security

  1. steal sensitive information from other users

  2. run scripts on other user's browser

  3. alter the communication protocol used by the site

  4. can potentially understand the query's structure

Show answer
Correct Option: D
Explanation:

To answer this question, the user needs to know what an SQL debug message is and how it can be exploited by an attacker.

An SQL debug message is a type of error message that can occur when there is an issue with an SQL query on a website or application. These messages can contain sensitive information about the query being executed, such as the database name, table name, and even the query itself.

Now, let's go through each option and explain why it is right or wrong:

A. steal sensitive information from other users: This option is possible because if an attacker can access the debug message, they can potentially see sensitive information about the database and query being executed. This information can be used to steal data from other users.

B. run scripts on other user's browser: This option is not directly related to an SQL debug message. It is more related to cross-site scripting (XSS) attacks, which are a different type of vulnerability.

C. alter the communication protocol used by the site: This option is not directly related to an SQL debug message. It is more related to protocol-level attacks, which are a different type of vulnerability.

D. can potentially understand the query's structure: This option is correct. An attacker who can access the SQL debug message can potentially understand the query's structure, which can be used to craft more effective SQL injection attacks.

Therefore, the correct answer is:

The Answer is: D

Which statement is true about network firewalls preventing Web Application attacks?
technology security

  1. Network firewalls cannot prevent attacks because ports 80 and 443 must be open

  2. If configured properly, network firewalls can prevent attacks

  3. Network firewalls cannot prevent attacks because its too comples to configure

  4. Network firewalls can prevent attacks because they can detect malicious HTTP traffic

Show answer
Correct Option: A
