ECCouncil 312-50 Exam Domains Q&A

Certified instructors verify every question for 100% accuracy, providing detailed, step-by-step explanations for each.

Question 1 ECCouncil 312-50
QUESTION DESCRIPTION:

env x=`(){ :;};echo exploit` bash -c ' cat /etc/passwd '

What is the Shellshock bash vulnerability attempting to do on a vulnerable Linux host?

  • A.

    Display passwd content to prompt

  • B.

    Removes the passwd file

  • C.

    Changes all passwords in passwd

  • D.

    Add new user to the passwd file

Correct Answer & Rationale:

Answer: A

Explanation:

To extract private information, attackers are using a couple of techniques. The simplest extraction attacks are in the form:

() {:;}; /bin/cat /etc/passwd

That reads the password file /etc/passwd, and adds it to the response from the web server. So an attacker injecting this code through the Shellshock vulnerability would see the password file dumped out onto their screen as part of the web page returned.

Question 2 ECCouncil 312-50
QUESTION DESCRIPTION:

An incident investigator asks to receive a copy of the event logs from all firewalls, proxy servers, and Intrusion Detection Systems (IDS) on the network of an organization that has experienced a possible breach of security. When the investigator attempts to correlate the information in all of the logs, the sequence of many of the logged events do not match up.

What is the most likely cause?

  • A.

    The network devices are not all synchronized.

  • B.

    Proper chain of custody was not observed while collecting the logs.

  • C.

    The attacker altered or erased events from the logs.

  • D.

    The security breach was a false positive.

Correct Answer & Rationale:

Answer: A

Explanation:

Time synchronization is an important middleware service of distributed systems, amongst which Distributed Intrusion Detection System (DIDS) makes extensive use of time synchronization in particular.

Question 3 ECCouncil 312-50
QUESTION DESCRIPTION:

During a recent security assessment, you discover the organization has one Domain Name Server (DNS) in a Demilitarized Zone (DMZ) and a second DNS server on the internal network.

What is this type of DNS configuration commonly called?

  • A.

    Split DNS

  • B.

    DNSSEC

  • C.

    DynDNS

  • D.

    DNS Scheme

Correct Answer & Rationale:

Answer: A

Explanation:

In a split DNS infrastructure, you create two zones for the same domain, one to be used by the internal network, the other used by the external network. Split DNS directs internal hosts to an internal domain name server for name resolution and external hosts are directed to an external domain name server for name resolution.

References: http://www.webopedia.com/TERM/S/split_DNS.html

Question 4 ECCouncil 312-50
QUESTION DESCRIPTION:

A hacker has successfully infected an internet-facing server which he will then use to send junk mail, take part in coordinated attacks, or host junk email content.

Which sort of trojan infects this server?

  • A.

    Botnet Trojan

  • B.

    Turtle Trojans

  • C.

    Banking Trojans

  • D.

    Ransomware Trojans

Correct Answer & Rationale:

Answer: A

Explanation:

In computer science, a zombie is a computer connected to the Internet that has been compromised by a hacker, computer virus or trojan horse and can be used to perform malicious tasks of one sort or another under remote direction. Botnets of zombie computers are often used to spread e-mail spam and launch denial-of-service attacks. Most owners of zombie computers are unaware that their system is being used in this way. Because the owner tends to be unaware, these computers are metaphorically compared to zombies. A coordinated DDoS attack by multiple botnet machines also resembles a zombie horde attack.

Question 5 ECCouncil 312-50
QUESTION DESCRIPTION:

Which of the following tools is used to analyze the files produced by several packet-capture programs such as tcpdump, WinDump, Wireshark, and EtherPeek?

  • A.

    tcptrace

  • B.

    tcptraceroute

  • C.

    Nessus

  • D.

    OpenVAS

Correct Answer & Rationale:

Answer: A

Explanation:

tcptrace is a tool for analysis of TCP dump files. It can take as input the files produced by several popular packet-capture programs, including tcpdump/WinDump/Wireshark, snoop, EtherPeek, and Agilent NetMetrix.

References: https://en.wikipedia.org/wiki/Tcptrace

Question 6 ECCouncil 312-50
QUESTION DESCRIPTION:

Which of the following is one of the most effective ways to prevent Cross-site Scripting (XSS) flaws in software applications?

  • A.

    Validate and escape all information sent to a server

  • B.

    Use security policies and procedures to define and implement proper security settings

  • C.

    Verify access right before allowing access to protected information and UI controls

  • D.

    Use digital certificates to authenticate a server prior to sending data

Correct Answer & Rationale:

Explanation:

Contextual output encoding/escaping could be used as the primary defense mechanism to stop Cross-site Scripting (XSS) attacks.

References: https://en.wikipedia.org/wiki/Cross-site_scripting#Contextual_outpu t_encoding.2Fescaping_of_string_input

Question 7 ECCouncil 312-50
QUESTION DESCRIPTION:

Which statement is TRUE regarding network firewalls preventing Web Application attacks?

  • A.

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

  • B.

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

  • C.

    Network firewalls can prevent attacks if they are properly configured.

  • D.

    Network firewalls cannot prevent attacks because they are too complex to configure.

Correct Answer & Rationale:

Answer: B

Explanation:

Network layer firewalls, also called packet filters, operate at a relatively low level of the TCP/IP protocol stack, not allowing packets to pass through the firewall unless they match the established rule set. To prevent Web Application attacks an Application layer firewall would be required.

References: https://en.wikipedia.org/wiki/Firewall_(comp uting)#Network_layer_or_packet_filters

Question 8 ECCouncil 312-50
QUESTION DESCRIPTION:

Which of the following programs is usually targeted at Microsoft Office products?

Correct Answer & Rationale:

Answer: C

Explanation:

A macro virus is a virus that is written in a macro language: a programming language which is embedded inside a software application (e.g., word processors and spreadsheet applications). Some applications, such as Microsoft Office, allow macro programs to be embedded in documents such that the macros are run automatically when the document is opened, and this provides a distinct mechanism by which malicious computer instructions can spread.

References: https://en.wik ipedia.org/wiki/Macro_virus

Question 9 ECCouncil 312-50
QUESTION DESCRIPTION:

Which of the following is a hardware requirement that either an IDS/IPS system or a proxy server must have in order to properly function?

  • A.

    Fast processor to help with network traffic analysis

  • B.

    They must be dual-homed

  • C.

    Similar RAM requirements

  • D.

    Fast network interface cards

Correct Answer & Rationale:

Answer: B

Explanation:

Dual-homed or dual-homing can refer to either an Ethernet device that has more than one network interface, for redundancy purposes, or in firewall technology, dual-homed is one of the firewall architectures, such as an IDS/IPS system, for implementing preventive security.

References: https://en.wikipedia.org/wiki/Dual-homed

Question 10 ECCouncil 312-50
QUESTION DESCRIPTION:

In order to show improvement of security over time, what must be developed?

  • A.

    Reports

  • B.

    Testing tools

  • C.

    Metrics

  • D.

    Taxonomy of vulnerabilities

Correct Answer & Rationale:

Answer: C

Explanation:

Today, management demands metrics to get a clearer view of security.

Metrics that measure participation, effectiveness, and window of exposure, however, offer information the organization can use to make plans and improve programs.
