Security and Recovery

Column: From the Trenches

From the Oct. 2008 Issue

Some of the biggest disasters are the ones that happen every day. A lost file
here, a crashed hard drive there, a virus infection that should have been caught,
an accidental deletion of an entire folder, a corruption of a database or a
myriad of other small issues. Prior to mega events like hurricane Katrina, the
losses from day-to-day issues were more than all natural disasters combined.
This month’s column is going to cover software, hardware appliances and
other services that can make you more secure and allow you to recover your firm

Fundamental protection should be in place such as firewalls and anti-virus
software. You should have a routine where you update your software frequently
and where daily backups are being made. Server technologies such as RAID drives
or other technologies such as virtualization should be considered if they are
not already in use. Once you have the fundamentals right, the categories below
can give you extra protection. The goal of listing the products below is to
give you ideas on how to protect your firm in the event of a failure. These
tools should either prevent a failure, or make it easier and faster to recover.

Let’s consider the first category of tools that are designed to protect
your individual computers as well as your network. Security software can help
protect your existing machines and network. PGP encryption is the protection
most widely recommended to encrypt local hard drives, and provide a level of
e-mail encryption, as well. Many states do not require reporting if the lost
machine has hard disk encryption installed. PGP takes several hours to encrypt
your computer’s hard drive, but once it is in place, there is no noticeable
difference in performance.

Preventing bad things from getting to your computers is the focus of the next
applications. Code Red can prevent the use of USB ports or wireless except under
certain circumstances. This product protects you from direct theft of data via
the USB port or unauthorized wireless use. TrustWare BufferZone provides protection
for all the things not covered by firewalls or anti-virus software. This product’s
claim to fame is application virtualization without any effort, but it also
protects confidential files and folders, prevents running forbidden files and
programs, offers external media protection, protects from e-mail attachments,
has the ability to eliminate unneeded files through Single-Click Cleaning, and
has a Real-Time Security Monitor.

For larger networks, New Boundary’s Policy Commander does automated
enforcement of policies, and its suite of products includes automation of most
desktop tasks. BOUNCER by CoreTrace takes a different approach, which could
eliminate the need for any anti-virus or protection software of any kind, including
the need to do software updates. This product locks down an image and prevents
software from being changed by any outside source. This provides version control
and completely eliminates the need for routine updates, a very interesting concept.

What happens if a machine turns up missing? Thirty-seven states currently
require reporting of lost personal data, and more will follow suit. If you have
the computer’s hard drive encrypted, you may eliminate the need for reporting,
but wouldn’t it be nice to know where the machine is, and wipe the data
clean? Tools like Computrace LoJack can do exactly this. In fact, many of these
products can trace through Internet connection, trace through Wi-Fi connection,
trace through telephone connection, gather forensics on the thief, use the computer’s
GPS to locate itself, take a picture of the crook with built-in camera, and
wipe out all the data on the hard drive when the machine is identified as stolen.
Some products are specifically designed to control and wipe out the data on
a machine, such as Beachhead’s Lost Data Solution.

The appliances that can protect you do several things. First, we think it
is important you have spam protection in place since many bad things come via
e-mail. The next thing we worry about is lost productivity in the office from
losing files or from losing the entire office. Appliances that provide Continuous
Data Protection (CDP) are becoming popular quickly because they backup all changed
files on the servers as well as the desktops, and copy the data off-site to
Internet backup facilities. Our approach, called Net Rescue, is an appliance
that backs up all data every 15 minutes for 48 hours.

Additionally, a backup is kept every day on the appliance for a week, and another
copy is kept for every week of the month. Nightly, the data is also backed up
off-site in two different locations. Individual files can be restored, or an
entire server can be restored. Further, on the Net Rescue appliance itself,
a virtual machine of the entire server, such as an Exchange Email server, can
be initialized and running in 12 to 15 minutes. If a complete site disaster
has occurred, the servers can be virtualized in the off-site backup facility,
and/or all data can be restored to an appliance to be shipped to the recovery
site. Other appliances protect your identity, passwords or other critical information
on USB keys such as IronKey or Yoggie.

Backup is critical, and there are many notable players in the market place.
Look for a provider that has multiple locations, can restore individual files,
encrypts all backup traffic, and will provide your data to you on hard drive
appliances for a major recovery.

If you’d prefer to just be rid of all servers, applications and backup
headaches, perhaps a hosting solution is in your future. The cost of hosting,
the quality of service and the availability of support is making the hosted
option more attractive all the time. We have listed some leading providers of
hosting services to tax and accounting firms.

The bottom line to security and recovery is preparation and testing. You should
consider the impact of using the technologies listed here in your firm. The
websites of these vendors are friendly, explain the technology, and often provide
a free trial of their product. You’ll be glad you took the effort if you
ever lose an important file or a whole system. If you’ve ever recreated
a document from scratch that should have been on a backup, these technologies
can really help. The day is coming where we will lose minimal data or time in
the event of a failure of any kind. ¦
