5. SNAPSHOT OF COST SAVINGS
The average domestic business trip costs $1,200 per participant per
meeting.
The average business meeting consists of 5 participants, 4 of whom
have to travel to get to the meeting.
The average employee per hour cost $ 60.
The savings in hours between doing a remote web conference (4 hrs) and
actually traveling to a place (21 hours) was (21-4=17 hours )per meeting per
participant.
Using these assumptions @ $ 60/hr ,this yields a savings of (17*
60=$1020 per meeting per participant.
Combining both the costs of business trip and employee cost ,a total
of $1200+ $1020 = $ 2220 per meeting per employee.
Therefore ,converting the average business meeting into a web
conferencing helps to realize total savings of apprx. $ 8,900 per
meeting.

Real-Time Transport Protocol(RTP).
Session Description protocol.(SDP).
Transport Layer Security(TLS).

5/27/2012 15

16. PROTOCOLS BEING USED TO SUPPORT REAL-
TIME DELIVERY OF INFORMATION IN WEB
CONFERENCING
Real-time transport Protocol(RTP)
A real-time end- to- end protocol utilizing existing
transport layers of data that has real-time properties.
Real-Time Control protocol: (RTCP)

A transport layer protocol designed for controlling the
transmission of audio and video over the internet.

17. FACTORS AFFECTING QUALITY OF
SERVICE IN WEB CONFERENCING
Latency/delay: It is the time required for a packet to travel
from its source to its destination across the network.
Packet loss/ Drops: Routers and switches contain buffers
to store packets when the network link lacks sufficient bandwidth to
transmit the packets at the moment. Packets get lost in the network
because of buffer overflows and congestion in the link. This could be
catastrophic for real-time applications such as video and voice.
Bandwidth: Unpredictable behavior of packets affects the
quality of service.( QoS).
5/27/2012 17

18. COMMON ATTACKS ON VoIP
NETWORK
DoS (Denial of service):The purpose of this attack is to
overload server or application and cause it to slow down.
MitM(Man in the middle):The attacker somehow positions
himself between the two hosts and prevents the packets sent between the
hosts from being received.
Eavesdropping: Attackers eavesdrop signaling traffic to discover
credentials ,calling patterns or other sensitive information.
Impersonation: User or host pretends to be another user or host.
Poisoning attacks: DNS poisoning targets the domain name
service application.
Hijacking/ Redirection :A type of attack in which one end-
point of communication is maliciously changed, usually after
identification, authentication and authorization .
5/27/2012 18

19. ATTACK METHODS IN VoIP
Port scans: Port scanning is a technique in which an attacker tries to open connections
to listening ports on a server.
Malicious codes: Malicious code is a broad term that describes any form of software
that is installed without authorization, notice or consent from the computer administrator.
This includes : * Virus
* Worms
* Trojans.
* Spyware
* Blended threat
Buffer overflow : A technique that targets an input parameter or value in a program
to deliberately cause a software failure.
Password theft/ Guessing: The password has very low entropy and is likely to be
susceptible to a brute force or dictionary attack in which commonly used word
combinations are tried repeatedly until a match is found.
Tunneling: This is an attack method by which one protocol rides inside another often
for the purpose of traversing the firewall.
Bid down: A bid down is one in which a man in the middle interferes with the negotiation
of a securely parameter and succeeds in fencing the other parties to agree to a lower
level of security. .

20. IMPLEMENTING SECURITY IN
VoIP NETWORK
AUTHENTICATION: I t is a process where a user confirms
his identity by presenting credentials that are difficult for anyone to
produce.
HONEYPOTS/HONEYNETS: A passive security
measure that uses deception techniques to observe and record the
activities of an attacker.
FIREWALLS:
 Protocol anomaly and intrusion detection.
 DoS prevention.
 User authentication.
5/27/2012 20

21. BUILDING BLOCKS OF
SECURITY IN VoIP
Authentication: Who you are?
Authorization: What you are allowed to do.
Integrity: If the information somehow get tampered
, this tampering can be detected.
Confidentiality: The data in transit between two
communicating parties cannot be made available to any
third parties.
Nonrepudiation: The originator of a message cannot
claim not to have sent a given message.
