312-50v10 : Certified Ethical Hacker v10 Exam : Part 06

  1. On performing a risk assessment, you need to determine the potential impacts when some of the critical business process of the company interrupt its service. What is the name of the process by which you can determine those critical business?

    • Risk Mitigation
    • Emergency Plan Response (EPR)
    • Disaster Recovery Planning (DRP)
    • Business Impact Analysis (BIA)
  2. Assume a business-crucial web-site of some company that is used to sell handsets to the customers worldwide. All the developed components are reviewed by the security team on a monthly basis. In order to drive business further, the web-site developers decided to add some 3rd party marketing tools on it. The tools are written in JavaScript and can track the customer’s activity on the site. These tools are located on the servers of the marketing company.

    What is the main security risk associated with this scenario?

    • External script contents could be maliciously modified without the security team knowledge
    • External scripts have direct access to the company servers and can steal the data from there
    • There is no risk at all as the marketing services are trustworthy
    • External scripts increase the outbound company data traffic which leads greater financial losses
  3. What type of analysis is performed when an attacker has partial knowledge of inner-workings of the application?

    • Black-box
    • Announced
    • White-box
    • Grey-box
  4. Bob finished a C programming course and created a small C application to monitor the network traffic and produce alerts when any origin sends “many” IP packets, based on the average number of packets sent by all origins and using some thresholds.

    In concept, the solution developed by Bob is actually:

    • Just a network monitoring tool
    • A signature-based IDS
    • A hybrid IDS
    • A behavior-based IDS
  5. Which of the following is a low-tech way of gaining unauthorized access to systems?

    • Scanning
    • Sniffing
    • Social Engineering 
    • Enumeration
  6. When tuning security alerts, what is the best approach?

    • Tune to avoid False positives and False Negatives
    • Rise False positives Rise False Negatives
    • Decrease the false positives
    • Decrease False negatives
  7. In an internal security audit, the white hat hacker gains control over a user account and attempts to acquire access to another account’s confidential files and information. How can he achieve this?

    • Privilege Escalation 
    • Shoulder-Surfing
    • Hacking Active Directory
    • Port Scanning
  8. Which regulation defines security and privacy controls for Federal information systems and organizations?

    • HIPAA
    • EU Safe Harbor
    • PCI-DSS
    • NIST-800-53
  9. Your company performs penetration tests and security assessments for small and medium-sized business in the local area. During a routine security assessment, you discover information that suggests your client is involved with human trafficking.

    What should you do?

    • Confront the client in a respectful manner and ask her about the data.
    • Copy the data to removable media and keep it in case you need it.
    • Ignore the data and continue the assessment until completed as agreed.
    • Immediately stop work and contact the proper legal authorities.
  10. You are a security officer of a company. You had an alert from IDS that indicates that one PC on your Intranet is connected to a blacklisted IP address (C2 Server) on the Internet. The IP address was blacklisted just before the alert. You are staring an investigation to roughly analyze the severity of the situation. Which of the following is appropriate to analyze?

    • Event logs on the PC
    • Internet Firewall/Proxy log
    • IDS log
    • Event logs on domain controller
  11. Identify the UDP port that Network Time Protocol (NTP) uses as its primary means of communication?

    • 123
    • 161
    • 69
    • 113
  12. It has been reported to you that someone has caused an information spillage on their computer. You go to the computer, disconnect it from the network, remove the keyboard and mouse, and power it down. What step in incident handling did you just complete?

    • Discovery
    • Recovery
    • Containment
    • Eradication
  13. Which of the following cryptography attack is an understatement for the extraction of cryptographic secrets (e.g. the password to an encrypted file) from a person by a coercion or torture?

    • Chosen-Cipher text Attack
    • Ciphertext-only Attack
    • Timing Attack
    • Rubber Hose Attack
  14. In cryptanalysis and computer security, ‘pass the hash’ is a hacking technique that allows an attacker to authenticate to a remote server/service by using the underlying NTLM and/or LanMan hash of a user’s password, instead of requiring the associated plaintext password as is normally the case.
    Metasploit Framework has a module for this technique: psexec. The psexec module is often used by penetration testers to obtain access to a given system whose credentials are known. It was written by sysinternals and has been integrated within the framework. The penetration testers successfully gain access to a system through some exploit, use meterpreter to grab the passwords or other methods like fgdump, pwdump, or cachedump and then utilize rainbowtables to crack those hash values.

    Which of the following is true hash type and sort order that is used in the psexec module’s ‘smbpass’ option?

    • LM:NT 
    • NTLM:LM
    • NT:LM
    • LM:NTLM
  15. You are looking for SQL injection vulnerability by sending a special character to web applications. Which of the following is the most useful for quick validation?

    • Double quotation
    • Backslash
    • Semicolon
    • Single quotation
  16. A virus that attempts to install itself inside the file it is infecting is called?

    • Tunneling virus
    • Cavity virus
    • Polymorphic virus
    • Stealth virus
  17. Bob, a system administrator at TPNQM SA, concluded one day that a DMZ is not needed if he properly configures the firewall to allow access just to servers/ports, which can have direct internet access, and block the access to workstations.

    Bob also concluded that DMZ makes sense just when a stateful firewall is available, which is not the case of TPNQM SA.

    In this context, what can you say?

    • Bob can be right since DMZ does not make sense when combined with stateless firewalls
    • Bob is partially right. He does not need to separate networks if he can create rules by destination IPs, one by one
    • Bob is totally wrong. DMZ is always relevant when the company has internet servers and workstations
    • Bob is partially right. DMZ does not make sense when a stateless firewall is available
  18. Sam is working as a pen-tester in an organization in Houston. He performs penetration testing on IDS in order to find the different ways an attacker uses to evade the IDS. Sam sends a large amount of packets to the target IDS that generates alerts, which enable Sam to hide the real traffic. What type of method is Sam using to evade IDS?

    • Denial-of-Service
    • False Positive Generation
    • Insertion Attack
    • Obfuscating
  19. Cross-site request forgery involves:

    • A request sent by a malicious user from a browser to a server
    • Modification of a request by a proxy between client and server
    • A browser making a request to a server without the user’s knowledge
    • A server making a request to another server without the user’s knowledge
  20. What does the option * indicate?
