QUESTION 61

Which of the following can be performed with software or hardware devices in order to record everything a person types using his keyboard?

 

A.

Warchalking

B.

Keystroke logging

C.

War dialing

D.

IRC bot

 

Correct Answer: B

Explanation:

Keystroke logging is a method of logging and recording user keystrokes. It can be performed with software or hardware devices. Keystroke logging devices can record everything a person types using his keyboard, such as to measure employee’s productivity on certain clerical tasks. These types of devices can also be used to get usernames, passwords, etc.

Answer option C is incorrect. War dialing is a technique of using a modem to automatically scan a list of telephone numbers, usually dialing every number in a local area code to search for computers, BBS systems, and fax machines. Hackers use the resulting lists for various purposes, hobbyists for exploration, and crackers (hackers that specialize in computer security) for password guessing.

Answer option A is incorrect. Warchalking is the drawing of symbols in public places to advertise an open Wi-Fi wireless network. Having found a Wi-Fi node, the warchalker draws a special symbol on a nearby object, such as a wall, the pavement, or a lamp post. The name warchalking is derived from the cracker terms war dialing and war driving.

Answer option D is incorrect. An Internet Relay Chat (IRC) bot is a set of scripts or an independent program that connects to Internet Relay Chat as a client, and so appears to other IRC users as another user. An IRC bot differs from a regular client in that instead of providing interactive access to IRC for a human user, it performs automated functions.

 

 

QUESTION 62

Fill in the blank with the appropriate term. A ______________ is a translation device or service that is often controlled by a separate Media Gateway Controller, which provides the call control and signaling functionality.

 

Correct Answer: Media gateway

Explanation:

A Media gateway is a translation device or service that converts digital media streams between disparate telecommunications networks such as PSTN, SS7, Next Generation Networks (2G, 2.5G and 3G radio access networks) or PBX. Media gateways enable multimedia communications across Next Generation Networks over multiple transport protocols such as Asynchronous Transfer Mode (ATM) and Internet Protocol (IP).Because the media gateway connects different types of networks, one of its main functions is to convert between different transmission and coding techniques. Media streaming functions such as echo cancellation, DTMF, and tone sender are also located in the media gateway. Media gateways are often controlled by a separate Media Gateway Controller, which provides the call control and signaling functionality.

Which of the following tools is a free laptop tracker that helps in tracking a user’s laptop in case it gets stolen?

 

A.

SAINT

B.

Adeona

C.

Snort

D.

Nessus

 

Correct Answer: B

Explanation:

Adeona is a free laptop tracker that helps in tracking a user’s laptop in case it gets stolen. All it takes is to install the Adeona software client on the user’s laptop, pick a password, and make it run in the background. If at one point, the user’s laptop gets stolen and is connected to the Internet, the Adeona software sends the criminal’s IP address. Using the Adeona Recovery, the IP address can then be retrieved. Knowing the IP address helps in tracking the geographical location of the stolen device.

Answer option D is incorrect. Nessus is proprietary comprehensive vulnerability scanning software. It is free of charge for personal use in a non-enterprise environment. Its goal is to detect potential vulnerabilities on tested systems. It is capable of checking various types of vulnerabilities, some of which are as follows:Vulnerabilities that allow a remote cracker to control or access sensitive data on a system Misconfiguration (e.g. open mail relay, missing patches, etc)

Default passwords, a few common passwords, and blank/absent passwords on some system accounts. Nessus can also call Hydra (an external tool) to launch a dictionary attack.Denials of service against the TCP/IP stack by using mangled packets.

Answer option A is incorrect. SAINT stands for System Administrator’s Integrated Network Tool. It is computer software used for scanning computer networks for security vulnerabilities, and exploiting found vulnerabilities. The SAINT scanner screens every live system on a network for TCP
and UDP services. For each service it finds running, it launches a set of probes designed to detect anything that could allow an attacker to gain unauthorized access, create a denial-of- service, or gain sensitive information about the network.

Answer option C is incorrect. Snort is an open source network intrusion detection system. The Snort application analyzes network traffic in realtime mode. It performs packet sniffing, packet logging, protocol analysis, and a content search to detect a variety of potential attacks.

Fill in the blank with the appropriate term. ______________is a powerful and low-interaction open source honeypot.

 

Correct Answer: Honeyd

Explanation:

Honeyd is a powerful and low-interaction open source honeypot. It was released by Niels Provos in 2002. It was written in C and designed for Unix platforms. It introduced a variety of new concepts, including the ability to monitor millions of unused IPs, IP stack spoofing, etc. It can also simulate hundreds of operating systems and monitor all UDP and TCP-based ports.

 

 

 

QUESTION 67

Which of the following statements are true about volatile memory?Each correct answer represents a complete solution. Choose all that apply.

 

A.

Read only memory (ROM) is an example of volatile memory.

B.

The content is stored permanently and even the power supply is switched off.

C.

A volatile storage device is faster in reading and writing data.

D.

It is computer memory that requires power to maintain the stored information.

 

Correct Answer: CD

Explanation:

Volatile memory, also known as volatile storage, is computer memory that requires power to maintain the stored information, unlike non-volatile memory which does not require a maintained power supply. It has been less popularly known as temporary memory. Most forms of modern random access memory (RAM) are volatile storage, including dynamic random access memory (DRAM) and static random access memory (SRAM). A volatile storage device is faster in reading and writing data.

Answer options B and A are incorrect. Non-volatile memory, nonvolatile memory, NVM, or non-volatile storage, in the most basic sense, is computer memory that can retain the stored information even when not powered. Examples of non-volatile memory include read-only memory, flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy disks, and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.

 

 

QUESTION 68

Which of the following firewalls are used to track the state of active connections and determine the network packets allowed to enter through the firewall?Each correct answer represents a complete solution. Choose all that apply.

 

A.

Circuit-level gateway

B.

Stateful

C.

Proxy server

D.

Dynamic packet-filtering

 

Correct Answer: BD

Explanation:

A dynamic packet-filtering firewall is a fourth generation firewall technology. It is also known as a stateful firewall. It tracks the state of active connections and determines which network packets are allowed to enter through the firewall. It records session information, such as IP addresses and port numbers to implement a more secure network. The dynamic packet-filtering firewall operates at Layer3, Layer4, and Layer5.

Answer option A is incorrect. A circuit-level gateway is a type of firewall that works at the session layer of the OSI model between the application layer and the transport layer of the TCP/IP stack. They monitor TCP handshaking between packets to determine whether a requested session is legitimate. Information passed to a remote computer through a circuit level gateway appears to have originated from the gateway. This is useful for hiding information about protected networks. Circuit-level gateways are relatively inexpensive and have the advantage of hiding information about the private network they protect.

Answer option C is incorrect. A proxy server firewall intercepts all messages entering and leaving the network. The proxy server effectively hides the true network addresses.

Answer options C and A are incorrect. All these statements are true about the FAT16 file system.

 

 

QUESTION 70

Fill in the blank with the appropriate term. The ____________ is used for routing voice conversations over the Internet. It is also known by other names such as IP Telephony, Broadband Telephony, etc.

 

Correct Answer: VoIP

Explanation:

The Voice over Internet Protocol (VoIP) is used for routing of voice conversation over the Internet. The VoIP is also known by other names such as IP Telephony, Broadband Telephony, etc. Analog signals are used in telephones in which the sound is received as electrical pulsation, which is amplified and then carried to a small loudspeaker attached to the other phone, and the call receiver can hear the sound. In VoIP, analog signals are changed into digital signals, which are transmitted on the Internet. VoIP is used to make free phone calls using an Internet connection, and this can be done by using any VoIP software available in the market. There are various modes for making phone calls through the Internet. Some of the important modes are as follows:

Through Analog Telephone Adapter (ATA)

In this mode, the traditional phone is attached to the computer through ATA.

ATA receives analog signals from the phone and then converts these signals to digital signals. The digital signals are then received by the Internet Service Providers (ISP), and the system is ready to make calls over VoIP.

Through IP Phone

IP Phones look exactly like the traditional phones, but they differ in that they have RJ-45 Ethernet connectors, instead of RJ-11 phone connectors, for connecting to the computers.

Computer To Computer

This is the easiest way to use VoIP. For this, we need software, microphone, speakers, sound card and an Internet connection through a cable or a DSL modem.

Soft Phones

Soft phone is a software application that can be loaded onto a computer and used anywhere in the broadband connectivity area.
