PORTABILITY AND CONNECTIVITY
- Software Portability An application is portable
across a class of environments to the degree that
the effort required to transport and adapt it to
a new environment in the class is less than the
effort of redevelopmentSee the following
website http//www.cs.wvu.edu/jdm/research/port
ability/home.htmlTools for portable
specifications, design, implementation, testing
and debugging, documentation, porting and
maintenance - Virtual Private Network (VPN)-VPN is a cost
effective, wide area network (WAN) solution for
businesses of all sizes. It allows you to
configure high-performance, site-to-site remote
access and intranet/extranet solutions to a
secure, standards-based environment. A VPN allows
remote employees to access corporate resources
through intermediate firewalls, proxies, NAT
devices, and the Internet - Private Line Services give you peace of mind
because your internal data, voice, and video
traffic is transmitted securely and quickly on a
private connection. If you need to protect your
business's domestic business communication
traffic, Domestic Private Line services and
network capabilities will meet your needs.
26Security Issues
PORTABILITY AND CONNECTIVITY
- VPN Security--VPNs are now the method of choice
for most corporations when it comes to remote
access. Unfortunately, many enterprises believe
their VPN will completely secure remote access to
sensitive corporate data from would be crackers.
The fact is, however, that users accessing a VPN
through an Internet connection often overlook the
exposure that they create for the enterprise.
There has been a substantial increase in the
number and types of internet based attacks to
subvert end user machines. In the past such
attacks were carried out by a select group of
highly skilled crackers. Now with the advent of
easy to use cracking scripts there is a new type
of threat, the Script Kiddies. With a few scripts
and little knowledge the teenager next door could
be trying to crack your machine - Wireless LAN Security--Wireless Access Points
(APs) are quickly becoming a convenient and
popular method of enabling wireless connectivity
in enterprises. Office workers can easily take
their laptops or wireless devices with them to
meetings or anywhere else within range and
maintain a network connection without the cables.
Unfortunately, many enterprises don't take in to
account the security ramifications of putting up
or allowing indiscriminate placement of APs.
Currently wireless APs offer very little in terms
of security and are prone to several types of
attacks. They are difficult to securely implement
and offer an easy backdoor into your enterprise
network.
27Security Issues(cont)
PORTABILITY AND CONNECTIVITY
- Server Security--Your servers store and control
critical services and data. Servers operate as
data repositories, email servers, printing
platforms, web servers, databases, directory
services, and much, much more. Unfortunately,
deployed security measures to protect servers
today are inadequate against the latest attacks
and exploits. Currently, out of the box Operating
Systems for servers offer very little in the way
of default security settings, and are thus prone
to unwelcome intrusions and data corruption,
weaknesses that can disrupt business operations
for hours, even days. Furthermore, keeping track
of the latest exploits and patches needed to
maintain server security can sap IT resources and
time. An unprotected server is the ideal window
of opportunity for a hacker or disgruntled
employee- steal corporate data and shut down a
network, all in a few, simple steps. - Internal Security--Independent analysts estimate
that sixty to seventy percent of the risk to
enterprise information comes from internal
sources. The risk is high because internal users
(including contractors) often have broad access
to, and extensive knowledge of, valuable
corporate information. Consequently, accidental
or malicious behavior initiated from the
workstation of an internal user can cause severe
damage.
28Security Issues(cont)
PORTABILITY AND CONNECTIVITY
- Healthcare Security--the global access and
sharing of healthcare information in a secure
private manner, anywhere, anytime. Finding and
implementing a security solution that that fits
with your companies needs should be a first
priority. By focusing on the HIPAA security
requirements for information being accessed,
transmitted and/or stored in electronic format, a
basic solution for all HIPAA-related security
questions needs to be addressed. Products that
cover the features that your enterprise must
implement to fulfill the HIPAA security
requirements need to be identified. Addition
needs for security solutions that allow you to
add other optional features to build a security
solution that fits your organizational needs,
without overspending on other security
technologies that may not actually be required is
another must for any corporation.
29Security Issues(cont)
PORTABILITY AND CONNECTIVITY
- Personal Firewalls--an advanced, user-friendly
personal firewall -- it is a bi-directional
intrusion defense system. Your personal computer
should be completely protected from malicious
hackers and other intruders while preventing
unauthorized access from your computer to a
network. In essence, Personal Firewalls make your
protected machines invisible to the outside
world. That makes Personal Firewalls a must-have
security measure for any PC that connects to a
private network or the public Internet. Once
you've been compromised, every other network you
connect to is at risk including your home,
business and online bank accounts. No matter
where you use your computer, whether remote or
behind a corporate firewall, whether dial-up or
an always-on broadband Internet connection,
Personal Firewalls gives you complete confidence
that your precious business, personal, financial
and other data is safe and secure. If that isn't
enough, Personal Firewalls includes advanced
active-scan vulnerability assessment to pinpoint
your weaknesses and fine-tune your security
policy.

- Secure Access-- develop secure networking
products for computers in varying home and work
environments. The Internet access product-lines
deliver not only best-of-breed networking
solutions for the home, home-office and
enterprise branch office, but also
enterprise-class security. When combined with the
ease-of-use, configurability and durability of
other security technologies, the product-line is
the perfect networking solution for environments
of all shapes and sizes.
