SmartPads SmartPad is a zippered notepad
portfolio, which captures handwritten notes on an
ordinary pad of paper and instantly sends them to
your Palm Organizer via its infrared port. Using
the enhanced SmartPad Palm applications, save
your notes, drawings, and maps in any of the four
major Palm applications. Using an optional modem
and third party software, you can email your
notes directly from your Palm. Top Brands

Software Portability Products
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.

Security 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.

27
Security 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.

28
Security 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.

29
Security 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.

Security Issues(cont)
PORTABILITY AND CONNECTIVITY
  • 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.
