The Task Of VoIP Security
Voice over Internet protocol (VOIP) is not a new phenomenon. It
has been around the business community for many years. But it's
increasing popularity among average citizens looking for more
affordable and technology-driven options in long distance
telephone service is becoming quite the phenomenon. As with any
"new" technology on the forefront, often the excitement of
getting the product out and available to the public precludes
any real consideration for issues such as security flaws. And
the consumers often don't consider such problems until it is too
late, like when they have fallen victim to a hacker. Just as
traditional telephone systems are vulnerable to breaches in
security, VOIP has its own, more complex security issues.
There has been very little implementation of VOIP security
systems to date. More than likely, this is because there has
been no really dangerous attack on an IP system yet. Most
customers of VOIP are likely more interested in cost and quality
than security at this point, have not heard of any notable
attacks. Waiting for that to happen, though, can be a costly and
inconvenient mistake. It is wise to consider being proactive in
securing VOIP phone systems, just as an organization does not
hesitate in securing their other information networks. Though
security products seem costly now, as the demand for VOIP
systems continue to increase, new VOIP security products will
likely be developed down the road that can be incorporated into
all-in-one applications to protect entire information networks.
This will make the possibility of an organization totally
securing its information and voice networks not so costly or
daunting to consider.
There are a few characteristics of VOIP that are particularly
vulnerable to security breaches, and subscribers to the service
should be aware of these. With VOIP, call information is logged
on call management boxes, where the VOIP services are also put
into action. These boxes are vulnerable to viruses and hackers'
attacks, which could result in a loss of data that might be
considered confidential to the organization. This could have a
snowball effect, compromising an organization's reliability and
trust with customers or clients, and cost them a lot of money
down the line in data retrieval and security upgrades. That is
why it is important to consider VOIP security from the outset,
and make certain that any data storage is safely guarded behind
a firewall.
Another potentially defenseless aspect of VOIP is the gateway
from which voice data is routed between the source and the
destination. These gateways are extremely susceptible to attacks
by hackers looking to gain the ability to make free telephone
calls. Eavesdropping should be yet another worry of those
subscribing to VOIP service. Hackers use special tools to find,
store, play back, and even alter voice data that they track
down. This can have devastating consequences for an organization
that might deal in highly sensitive or confidential information.
Encrypting VOIP voice traffic, using firewalls, and restricting
access by using an alternate domain for VOIP traffic and
restricting the use of that domain through an access list are
but a few of the ways to cut any VOIP security issues off at the
pass.
Not considering the potential security issues that could arise
using VOIP phone technology is not wise. Waiting for something
to happen and trying to solve the problem after the fact can be
costly for an organization, both for its customers and
associates and its bottom line. When email was a new and
exciting technology, security was not thought much of, until
worms and viruses began infesting the inboxes of people
worldwide. And now it seems that email security measures are
struggling to keep up with the potential dangers. Knowing that
there is a potential for disaster, and being proactive in trying
to prevent sensitive voice data from being hacked and stolen by
investing in VOIP security systems on the outset is the best way
to get the most out of VOIP phone technology.
