QUESTION 107
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

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.

QUESTION 108

Transport layer

Link layer

Internet layer

Application layer

QUESTION 110
What is the range for registered ports?

QUESTION 112
Which of the following is a distributed multi-access network that helps in supporting integrated communications using a dual bus and distributed queuing?

Logical Link Control

Token Ring network

Distributed-queue dual-bus

CSMA/CA

In telecommunication, a distributed-queue dual-bus network (DQDB) is a distributed multi-access network that helps in supporting integrated communications using a dual bus and distributed queuing, providing access to local or metropolitan area networks, and supporting connectionless data transfer, connection-oriented data transfer, and isochronous communications, such as voice communications. IEEE 802.6 is an example of a network providing DQDB access methods. Answer option B is incorrect. A Token Ring network is a local area network (LAN) in which all computers are connected in a ring or star topology and a bit- or token-passing scheme is used in order to prevent the collision of data between two computers that want to send messages at the same time. The Token Ring protocol is the second most widely-used protocol on local area networks after Ethernet. The IBM Token Ring protocol led to a standard version, specified as IEEE
802.5. Both protocols are used and are very similar. The IEEE 802.5 Token Ring technology provides for data transfer rates of either 4 or 16 megabits per second. Answer option A is incorrect. The IEEE 802.2 standard defines Logical Link Control (LLC). LLC is the upper portion of the data link layer for local area networks. Answer option D is incorrect. Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) is an access method used by wireless networks (IEEE 802.11). In this method, a device or computer that transmits data needs to first listen to the channel for an amount of time to check for any activity on the channel. If the channel is sensed as idle, the device is allowed to transmit data. If the channel is busy, the device postpones its transmission. Once the channel is clear, the device sends a signal telling all other devices not to transmit data, and then sends its packets. In Ethernet (IEEE 802.3) networks that use CSMA/CD, the device or computer continues to wait for a time and checks if the channel is still free. If the channel is free, the device transmits packets and waits for an acknowledgment signal indicating that the packets were received.

QUESTION 113
Rick has implemented several firewalls and IDS systems across his enterprise network. What should he do to effectively correlate all incidents that pass through these security controls?

Use firewalls in Network Address Transition (NAT) mode

Implement IPsec

Implement Simple Network Management Protocol (SNMP)

Use Network Time Protocol (NTP)

QUESTION 114
Which of the following tools examines a system for a number of known weaknesses and alerts the administrator?

Nessus

COPS

SATAN

SAINT

Final Thoughts

With the recent technological advancements, computer networks are no longer the simple connection of servers and systems managed by network administrators they used to be. They are complex infrastructures that have reduced the globe to a small village. But with this comes the consistent threat of digital attacks. To evade such incidents, most of the independent certification vendors such as the EC-Council are moving ahead of time to create certification paths to validate security experts who can act as the last line of defense against security incidents. Well, if getting a job in this path makes sense to you, check out the EC-Council Certified Network Defender designation alongside 312-38 evaluation. Simply put, it is a rewarding career track, to say the least.
