QUESTION: 16

Which of the following is a protocol that describes an approach to providing "streamlined" support of OSI application services on top of TCP/IP-based networks for some constrained environments?

Network News Transfer Protocol
Lightweight Presentation Protocol
Internet Relay Chat Protocol
Dynamic Host Configuration Protocol

Answer(s): B

Explanation:

Lightweight Presentation Protocol (LPP) is a protocol that describes an approach to providing "streamlined" support of OSI application services on top of TCP/IP-based networks for some constrained environments. This protocol was initially derived from a requirement to run the ISO Common Management Information Protocol (CMIP) in TCP/IP-based networks.
This protocol is designed for a particular class of OSI applications, namely those entities whose application context includes only an Association Control Service Element (ACSE) and a Remote Operations Service Element (ROSE).
Answer option D is incorrect. The Dynamic Host Configuration Protocol (DHCP) is a computer networking protocol used by hosts (DHCP clients) to retrieve IP address assignments and other configuration information. DHCP uses a client-server architecture. The client sends a broadcast request for configuration information. The DHCP server receives the request and responds with configuration information from its configuration database. In the absence of DHCP, all hosts on a network must be manually configured individually - a time-consuming and often error-prone undertaking. DHCP is popular with ISP's because it allows a host to obtain a temporary IP address.
Answer option A is incorrect. Answer option C is incorrect. Internet Relay Chat (IRC) is a chat service, which is a client-server protocol that supports real-time text chat between two or more users over a TCPIP network.

QUESTION: 17

You are an Administrator for a network at an investment bank. You are concerned about individuals breeching your network and being able to steal data before you can detect their presence and shut down their access. Which of the following is the best way to address this issue?

Implement a strong password policy.
Implement a strong firewall.
Implement a honeypot.
Implement network based antivirus.

Answer(s): C

Explanation:

A honey pot is designed to attract intruders to a false server that has no real data (but may seem to have valuable data). The specific stated purpose of a honey pot is as a backup plan in case an intruder does gain access to your network.
Answer option B is incorrect. The firewall may help reduce the chance of an intruder gaining access, but won't help protect you once they have gained access.

QUESTION: 18

Which of the following is the practice of sending unwanted e-mail messages, frequently with commercial content, in large quantities to an indiscriminate set of recipients? Each correct answer represents a complete solution. Choose all that apply.

E-mail spam
Junk mail
Email spoofing
Email jamming

Answer(s): A,B

Explanation:

E-mail spam, also known as unsolicited bulk email (UBE), junk mail, or unsolicited commercial email (UCE), is the practice of sending unwanted e-mail messages, frequently with commercial content, in large quantities to an indiscriminate set of recipients.
Answer option C is incorrect. Email spoofing is a fraudulent email activity in which the sender address and other parts of the email header are altered to appear as though the email originated from a different source. Email spoofing is a technique commonly used in spam and phishing emails to hide the origin of the email message.
By changing certain properties of the email, such as the From, Return-Path and Reply-To fields (which can be found in the message header), ill-intentioned users can make the email appear to be from someone other than the actual sender. The result is that, although the email appears to come from the address indicated in the From field (found in the email headers), it actually comes from another source.
Answer option D is incorrect. Email jamming is the use of sensitive words in e-mails to jam the authorities that listen in on them by providing a form of a red herring and an intentional annoyance. In this attack, an attacker deliberately includes "sensitive" words and phrases in otherwise innocuous emails to ensure that these are picked up by the monitoring systems. As a result, the senders of these emails will eventually be added to a "harmless" list and their emails will be no longer intercepted, hence it will allow them to regain some privacy.

QUESTION: 19

FILL BLANK
Fill in the blank with the appropriate word. The________________ risk analysis process analyzes the effect of a risk event deriving a numerical value.

quantitative

Answer(s): A

Explanation:

Quantitative risk analysis is a process to assess the probability of achieving particular project objectives, to quantify the effect of risks on the whole project objective, and to prioritize the risks based on the impact to the overall project risk. The quantitative risk analysis process analyzes the effect of a risk event deriving a numerical value. It also presents a quantitative approach to build decisions in the presence of uncertainty. The inputs for quantitative risk analysis are as follows:
Organizational process assets Project scope statement
Risk management plan Risk register
Project management plan

QUESTION: 20

Which of the following is a tool that runs on the Windows OS and analyzes iptables log messages to detect port scans and other suspicious traffic?

Nmap
Hping
NetRanger
PSAD

Answer(s): D

Explanation:

PSAD is a tool that runs on the Windows OS and analyzes iptables log messages to detect port scans and other suspicious traffic. It includes many signatures from the IDS to detect probes for various backdoor programs such as EvilFTP, GirlFriend, SubSeven, DDoS tools (mstream, shaft), and advanced port scans (FIN, NULL, XMAS). If it is combined with fwsnort and the Netfilter string match extension, it detects most of the attacks described in the Snort rule set that involve application layer data.
Answer option C is incorrect. NetRanger is the complete network configuration and information toolkit that includes the following tools: Ping tool, Trace Route tool, Host Lookup tool, Internet time synchronizer, Whois tool, Finger Unix hosts tool, Host and port scanning tool, check multiple POP3 mail accounts tool, manage dialup connections tool, Quote of the day tool, and monitor Network Settings tool. These tools are integrated in order to use an application interface with full online help. NetRanger is designed for both new and experienced users. This tool is used to help diagnose network problems and to get information about users, hosts, and networks on the Internet or on a user computer network. NetRanger uses multi-threaded and multi-connection technologies in order to be very fast and efficient.
Answer option B is incorrect. Hping is a free packet generator and analyzer for the TCP/IP protocol. Hping is one of the de facto tools for security auditing and testing of firewalls and networks. The new version of hping, hping3, is scriptable using the Tcl language and implements an engine for string based, human readable description of TCP/IP packets, so that the programmer can write scripts related to low level TCP/IP packet manipulation and analysis in very short time. Like most tools used in computer security, hping is useful to both system administrators and crackers (or script kiddies).
Answer option A is incorrect. Nmap is a free open-source utility for network exploration and security auditing. It is used to discover computers and services on a computer network, thus creating a "map" of the network. Just like many simple port scanners, Nmap is capable of discovering passive services. In addition, Nmap may be able to determine various details about the remote computers. These include operating system, device type, uptime, software product used to run a service, exact version number of that product, presence of some firewall techniques and, on a local area network, even vendor of the remote network card. Nmap runs on Linux, Microsoft Windows, etc.
