EC-COUNCIL EC-Council Certified Security Analyst (ECSA) Sample Questions:

1. John, the penetration tester in a pen test firm, was asked to find whether NTP services are opened on the target network (10.0.0.7) using Nmap tool.

Which one of the following Nmap commands will he use to find it?

A) nmap -sU -p 123 10.0.0.7
B) nmap -sU -p 389 10.0.0.7
C) nmap -sU -p 161 10.0.0.7
D) nmap -sU -p 135 10.0.0.7

2. SQL injection attacks are becoming significantly more popular amongst hackers and there has been an estimated 69 percent increase of this attack type.
This exploit is used to great effect by the hacking community since it is the primary way to steal sensitive data from web applications. It takes advantage of non-validated input vulnerabilities to pass SQL commands through a web application for execution by a back-end database.
The below diagram shows how attackers launched SQL injection attacks on web applications.

Which of the following can the attacker use to launch an SQL injection attack?

A) Blah' or 1=1 -
B) Blah' and 2=2 -
C) Blah' and 1=1 -
D) Blah' "2=2 -"

3. A wireless intrusion detection system (WIDS) monitors the radio spectrum for the presence of unauthorized, rogue access points and the use of wireless attack tools. The system monitors the radio spectrum used by wireless LANs, and immediately alerts a systems administrator whenever a rogue access point is detected.
Conventionally it is achieved by comparing the MAC address of the participating wireless devices.
Which of the following attacks can be detected with the help of wireless intrusion detection system (WIDS)?

A) Man-in-the-middle attack
B) SQL injection
C) Parameter tampering
D) Social engineering

4. A Blind SQL injection is a type of SQL Injection attack that asks the database true or false questions and determines the answer based on the application response. This attack is often used when the web application is configured to show generic error messages, but has not mitigated the code that is vulnerable to SQL injection.

It is performed when an error message is not received from application while trying to exploit SQL vulnerabilities. The developer's specific message is displayed instead of an error message. So it is quite difficult to find SQL vulnerability in such cases.
A pen tester is trying to extract the database name by using a blind SQL injection. He tests the database using the below query and finally finds the database name.
http://juggyboy.com/page.aspx?id=1; IF (LEN(DB_NAME())=4) WAITFOR DELAY '00:00:10'--
http://juggyboy.com/page.aspx?id=1; IF (ASCII(lower(substring((DB_NAME()),1,1)))=97) WAITFOR DELAY '00:00:10'--
http://juggyboy.com/page.aspx?id=1; IF (ASCII(lower(substring((DB_NAME()),2,1)))=98) WAITFOR DELAY '00:00:10'--
http://juggyboy.com/page.aspx?id=1; IF (ASCII(lower(substring((DB_NAME()),3,1)))=99) WAITFOR DELAY '00:00:10'--
http://juggyboy.com/page.aspx?id=1; IF (ASCII(lower(substring((DB_NAME()),4,1)))=100) WAITFOR DELAY '00:00:10'--
What is the database name?

A) WXYZ
B) EFGH
C) ABCD
D) PQRS

5. The Web parameter tampering attack is based on the manipulation of parameters exchanged between client and server in order to modify application data, such as user credentials and permissions, price and quantity of products, etc. Usually, this information is stored in cookies, hidden form fields, or URL Query Strings, and is used to increase application functionality and control.
This attack takes advantage of the fact that many programmers rely on hidden or fixed fields (such as a hidden tag in a form or a parameter in a URL) as the only security measure for certain operations. Attackers can easily modify these parameters to bypass the security mechanisms that rely on them.

What is the best way to protect web applications from parameter tampering attacks?

A) Using an easily guessable hashing algorithm
B) Applying effective input field filtering parameters
C) Validating some parameters of the web application
D) Minimizing the allowable length of parameters
