Answer

B. Tenanting-Provides for the possibility to break into a busy line to inform another user an important message

Explanation

The word INCORRECTLY was the keyword used in the question. You need to find out the incorrectly described PBX feature from given options.

The Tenanting feature is incorrectly described.

Tenanting limits system user access to only those users who belong to the same tenant group – useful when one company leases out part of its building to other companies and tenants share an attendant, trunk lines,etc

For your exam you should know below mentioned PBX features and Risks:

System Features –

Description –

Risk –

Automatic Call distribution –

Allows a PBX to be configured so that incoming calls are distributed to the next available agent or placed on-hold until one become available

Tapping and control of traffic –

Call forwarding –

Allow specifying an alternate number to which calls will be forwarded based on certain condition

User tracking –

Account codes –

Used to:

Track calls made by certain people or for certain projects for appropriate billing

Dial-In system access (user dials from outside and gain access to normal feature of the PBX)

Changing the user class of service so a user can access a different set of features (i.e. the override feature)

Fraud, user tracking, non authorized features

Access Codes –

Key for access to specific feature from the part of users with simple instruments, i.e. traditional analog phones.

Non-authorized features –

Silent Monitoring –

CISA Question 1300

Question

Which of the following is a sophisticated computer based switch that can be thought of as essentially a small in-house phone company for the organization?

A. Private Branch Exchange
B. Virtual Local Area Network
C. Voice over IP
D. Dial-up connection

Answer

A. Private Branch Exchange

Explanation

A Private Branch Exchange(PBX) is a sophisticated computer based switch that can be thought of as essentially a small in-house phone company for the organization that operates it. Protection of PBX is thus a height priority. Failure to secure PBX can result in exposing the organization to toll fraud, theft of proprietary or confidential information, loss of revenue or legal entanglements.

PBX environment involves many security risks, presented by people both internal and external to an organization. The threat of the PBX telephone system is many, depending on the goals of these attackers, and include:

  • Theft of service – Toll fraud, probably the most common of motives for attacker.
  • Disclosure of Information – Data disclosed without authorization, either by deliberate actionably accident. Examples includes eavesdropping on conversation and unauthorized access to routing and address data.
  • Data Modification – Data altered in some meaningful way by recording, deleting or modifying it. For example, an intruder may change billing information or modify system table to gain additional services.
  • Unauthorized access – Actions that permit an unauthorized user to gain access to system resources or privileges.
  • Denial of service – Actions that prevent the system from functioning in accordance with its intended purpose. A piece of equipment or entity may be rendered inoperable or forced to operate in a degraded state; operations that depend on timeliness may be delayed.
  • Traffic Analysis – A form of passive attack in which an intruder observes information about calls and make inferences, e.g. from the source and destination number or frequency and length of messages. For example, an intruder observes a high volume of calls between a company’s legal department and patent office, and conclude that a patent is being filed.

The following were incorrect answers:

  • Virtual Local Area Network – A virtual local area network (VLAN) is a logical group of workstations, servers and network devices that appear to be on the same LAN despite their geographical distribution. A VLAN allows a network of computers and users to communicate in a simulated environment as if they exist in a single LAN and are sharing a single broadcast and multicast domain. VLANs are implemented to achieve scalability, security and ease of network management and can quickly adapt to change in network requirements and relocation of workstations and server nodes.
  • Voice over IP – VoIP is a technology where voice traffic is carried on top of existing data infrastructure. Sounds are digitalized into IP packets and transferred through the network layer before being decode back into the original voice.
  • Dial-up connection – Dial-up refers to an Internet connection that is established using a modem. The modem connects the computer to standard phone lines, which serve as the data transfer medium. When a user initiates a dial-up connection, the modem dials a phone number of an Internet Service Provider (ISP) that is designated to receive dial-up calls. The ISP then establishes the connection, which usually takes about ten seconds and is accompanied by several beeping an buzzing sounds.
