Introduction
Computers and the Internet have transformed the practice
of law, and how lawyers handle confidential client information.
Where once paper documents were the norm, today clients,
lawyers, and law office staff routinely work with electronic
documents and data. Protecting the security and confidentiality
of that information, however, is as important today
as ever: Both the Rules of Professional Conduct and
the Personal Information Protection and Electronic Documents
Act (PIPEDA) apply equally to paper-based files and
to electronic documents, such as a computer files or
e-mail messages.
A failure to take appropriate steps to protect the
electronic data in your office could have disastrous
consequences. This could include an embarrassing release
of sensitive information, a malpractice claim, a complaint
to the Law Society, or the theft of your personal identity.
At the very least, the theft, loss, or destruction of
client or practice-related data will be disruptive to
you and your practice. In the extreme case, it could
cause your practice to fail.
To minimize the risk of any disclosure or loss of confidential
client or practice data, you should understand where
the risks are, and implement office management practices
and appropriate technology to ensure all of your data
remains confidential and secure.
This booklet provides a comprehensive review of various
steps you should take to ensure that the electronic
information in your office remains confidential and
secure. Although some of the suggested steps may not
be relevant to every lawyer, all practitioners will
find helpful information in this booklet. Even if you
do not have the expertise to implement the suggested
measures yourself, you’ll be in a better position
to direct the work that technology consultants or others
must do for you.
If you do nothing else – the lucky 13 things
you must do
An unprotected computer can be infected or hacked within
seconds of connecting to the Internet, so protecting
your electronic data is a must. The question is: How
much time, effort and money are you willing to invest
in that task? Ultimately, you need to find a balance
between the allowable risk and an acceptable cost and
effort. From a best practices point of view, there are
13 steps that you should systematically take to protect
the electronic data in your firm against the most common
threats. Most can be completed quickly, and at little
or no cost. More detail on the first four steps is provided
in the remainder of this booklet.
Step #1 Install latest updates to eliminate
security vulnerabilities: The networking functionality
built into software that allows the Internet to operate
can create security vulnerabilities that in turn can
allow computers to be compromised by hackers. Microsoft
products are particularly vulnerable. You must protect
yourself by installing the latest security patches and
updates.
Step #2 Make full and proper use of passwords:
We all have more passwords than we can remember,
and as a result, we get lazy and use obvious ones, or
we don’t use them at all. You must use passwords,
and use them properly to keep your data safe.
Step #3 Antivirus software is essential: Computer
viruses are a fact of life. Every computer in every
law office should have antivirus software on it, and
this software needs to be frequently updated, at least
weekly. Make sure you understand how to properly use
and configure your antivirus software.
Step #4 Avoid spyware and adware: Viruses
used to be the only threat that you had to worry about.
Now you need to be aware of several other malicious
software threats, including some that will spy on you.
Odds are they are already on your computer. You need
to take steps to make sure no one is watching your surfing
habits, or collecting personal or client information
from your computer.
Step1: Install latest updates to eliminate security
vulnerabilities
Computer software programs sold today are incredibly
complex. Microsoft Windows XP, for example, has more
than forty million lines of code written by thousands
of programmers. Not surprisingly, programs often contain
coding errors that were not detected prior to their
release, and that can create problems, ranging from
non-functioning features or functions to program lockups
or crashes that result in data loss or file corruption.
These same coding errors can also cause security vulnerabilities
that a hacker can exploit to access or destroy data,
or run programs on a vulnerable computer, without the
computer owner’s knowledge. Once hackers become
aware of a security vulnerability, they use tools to
search the Web for computers that are open to attack.
To address these issues, software vendors make available
updates or patches – usually as free downloads
on the software vendor’s Web site. They are also
sometimes called service packs. You should regularly
check that you have all the latest updates for all the
programs on your computer.
Microsoft product users beware
Because Microsoft products are particularly prone to
security vulnerabilities, you should update all Microsoft
software regularly. Be aware if you are using any version
of the Microsoft Windows operating system (Windows 98,
Windows Me, Windows NT, Windows 2000 or Windows XP),
Word, Excel, PowerPoint, Internet Explorer, Exchange
Server, Outlook or Outlook Express.
Updates to Microsoft Windows: Go to www.windowsupdate.com
and follow the instructions. The tools on this Web page
will review the Windows software on your computer (without
sending information to Microsoft), and tell you what
updates are available. Those that address security vulnerabilities
are identified as critical updates. Other Windows and
driver updates will also be listed. You don’t
have to install all available updates, but you should
work through and install all security-related updates.
Some security updates must be installed individually,
and most require that you restart your computer after
they have been installed.
Updates for Microsoft Office applications such as Word:
Go to http://office.microsoft.com/
and follow the instructions.
Windows Automatic Update
Windows Automatic Update (formerly called Critical
Update Notification) streamlines the updating process
by notifying you when critical updates are available
for your computer. Once activated, Automatic Update
periodically checks with the Microsoft Web site for
any critical updates for your system. It automatically
downloads updates and notifies you when they need to
be installed. All you do is wait for the installation
prompt to appear and follow the on-screen instructions
to complete the installation.
For greater control and automation, there are other
products for managing the installation of updates from
a central location.
Be careful with Windows XP Service Pack 2
Although Microsoft’s Service Pack 2 update (SP2)
for Windows XP contains some important security updates,
users have reported problems with various programs and
hardware operating properly afterwards. Before you install
SP2, do some research to ensure it will not cause problems
with the programs and hardware on your computer. For
more information see www.microsoft.com/windowsxp/sp2/sp2_whattoknow.mspx.
Update all your software
If you are using non-Microsoft PC software, check for
updates on the product’s Web site. Sometimes direct
links to an updates Web page can be found on the Help
menu. Click on Help, then look for a link to a Web updates
page. Otherwise, you should be able to find the product’s
site with a search on Google. You are not immune to
vulnerabilities if you use Linux or a Mac; these also
need to be updated.
Backup before you install updates
Installing updates can interfere with the way a program
works, or with the operation of the computer itself.
Back up data on your computer before you install patches
or updates. See page 45 for more information on backups.
Step #2: Make full and proper use of passwords
We all have more passwords than we can easily remember,
and as a result, we get lazy and use obvious passwords,
or we don’t use them at all. However, like the
keys that open your front door or start your car, computer
passwords “unlock” your computer. They are
essential for properly securing and accessing electronic
data so you need to be conscientious about how you set
them up and use them.
How to properly use passwords
The following are steps you can take to use passwords
more effectively:
- Never write down your password, especially on your
monitor. Take a walk around your office and see how
many passwords you can find on monitors.
- If you absolutely have to write down some of your
passwords to remember them, don’t write them
out exactly. Write them out so they have to be translated
in some way. For example, add or delete a character,
transpose letters, or vary them in some other consistent
way that only you can figure out.
- Don’t tell anyone your passwords, ever. You
are the only one who needs to know your passwords.
Once someone else knows your password, you lose control
over who can access your computer.
- Change any compromised password immediately. To
be completely safe, you should change your passwords
even if you only suspect they have been compromised.
- Don’t use the same password for everything
as this gives someone full and easy access to your
entire system if they know that password. Try to use
different passwords for different programs, especially
for important or sensitive applications such as network
logon or bank accounts
- On Windows 2000 and XP computers, don’t have
identical passwords for your network logon and administrator
account passwords.
- Change your network and other important passwords
every 60 to 90 days. This will frustrate people who
have your password without your knowledge.
- Be careful about where you save passwords on your
computer. Too often users have a Word or WordPerfect
file with all their passwords in it. This file can
be located in seconds, especially if it is called
password.doc, or if it contains the word “password.”
Consider getting a tool such as Password Manager XP
(www.cp-lab.com)
which will store your passwords on your computer in
an encrypted and password-protected database.
- Be wary of dialog boxes, such as those for remote
access and other telephone connections that let you
save or remember your password. Do not select this
option as it makes your password available to anyone
who accesses your computer. Similarly, don’t
let your browser remember your Web site passwords.
Creating “strong” passwords
Create passwords that are harder to guess or figure
out. These are called strong passwords and they are
more difficult for password-cracking tools to determine.
Password-cracking software uses one of three approaches:
intelligent guessing, dictionary attacks, and automation.
Automation is sometimes called brute force as it simply
tries every possible combination of characters. Given
enough time, the automated method can crack any password.
However, it still can take months to crack a strong
password.
- For a password to be “strong”, it should:
- Be at least eight characters long;
- Contain at least one character from each of the
following four groups:
- Uppercase letters A, B, C, ...;
- Lowercase letters a, b, c, ...;
- Numerals 0, 1, 2, 3, 4, 5, 6, 7, 8, 9; and
- Symbols (all characters not defined as letters
or numerals, including: ` ~ ! @ Step $ % ^ &
* ( ) _ + - = { } | [ ] \ : “ ; ‘
< > ? , . /
- Have at least one symbol character in the second
through sixth positions;
- Be significantly different from any passwords
you have used previously;
- Not contain your name or your computer user
name; and
- Not be a common word or name.
Treating passwords as confidential keys to your computer
helps properly secure your firm and client data.
Step #3: Antivirus software is essential
Antivirus software is essential to protect your computer
and data from malware – the generic name for computer
programs such as worms and viruses that are designed,
as the name suggests, solely for malicious purposes.
Viruses
Like their biological namesakes, viruses are small
programs that infect other programs on other computers,
and in the process replicate and spread themselves further.
Most viruses distribute themselves by e-mail, but they
can also be spread by diskettes, and in many types of
computer files, including Microsoft Word documents.
Viruses bury themselves deep within the executable code
in the programs they infect, making it difficult, if
not impossible, to detect their presence, often after
damage or data loss has occurred. There are tens of
thousands of known viruses.
Worms
Worms are an even bigger threat because they replicate
more easily than viruses. They embed themselves in e-mail
messages or Web pages, lying dormant until the computer
user opens an infected e-mail or accesses an infected
Web page, at which time they will spread rapidly. Two
of the more recent major worm incidents saw millions
of computers across every continent infected in less
than ten minutes.
Trojan Horses
Inspired by ancient Greek mythology, Trojan horse programs
sneak malicious code onto your computer by hiding themselves
within safe-looking programs, such as screen savers,
games, titillating images, and other free downloads.
Like other malware, Trojan horses can destroy your computer
data or capture and share confidential information.
See page 16 for more information on adware and spyware.
Antivirus software
Antivirus software effectively prevents virus and worm
infections, although it may slow your computer down
a bit. Once installed, the software continuously monitors
other programs running on your computer. It will attempt
to stop any virus activity it detects, hopefully in
time to prevent further infections and data loss or
damage.
The type of antivirus software you select depends
on your computer. For computers that are not networked
or are on a peer-to-peer network, use “personal”
versions. Some corporate versions operate from a central
server, others protect an e-mail server. No matter which
type you select, antivirus software should be installed
on all computers in your office — even those not
connected to the Internet.
The two most widely used antivirus programs are Norton
Antivirus (www.symantec.com)
and VirusScan (www.mcafee.com).
Expect to pay $40-$60 per computer to buy the software,
plus an additional annual fee for virus signature file
updates (see below). Buying antivirus software that
is bundled with other products, such as firewall and
anti-spam software, will save you money.
A free program that is a good option for a home computer
is the AVG antivirus program from Grisoft (www.grisoft.com).
To scan a computer that doesn’t have antivirus
software on it, consider Housecall (www.trendmicro.com)
and ActiveScan (www.panda
software.com/activescan).
Installing antivirus software however is only the start:
You also need to regularly update your virus definition
or signature files. Antivirus programs use the information
in these files to recognize virus infections when they
are occurring. As there are new viruses being created
every day, you need to have the most recently released
virus signature file to be protected against all possible
infections. The updates to these files are available
on your antivirus software’s Web site. Expect
to pay about $30 -$40 per year for these updates, starting
on the first anniversary of your installation.
Most antivirus software programs can be configured
to download these updates automatically, without user
intervention. Make sure the automatic update feature
is enabled in your antivirus software as this ensures
that your protection is always up-to-date.
Lastly, and most importantly, run your antivirus software
to scan your entire hard disk(s) at least weekly, either
manually or automatically.
Step #4: Avoid spyware and adware
Of far greater practical threat than any worms or viruses
are adware and spyware – two new types of malware
that likely have already infected your computers, unless
you have taken specific steps to protect yourself and
clean them from your systems.
Adware
Adware is software that tracks your surfing habits,
and displays targeted pop-up advertisements on your
computer based on Web sites visited or search terms
used. Pop-ups are the advertisements that appear
in separate browser windows while you are surfing the
Web. In some cases, adware can also modify the settings
on your computer. To protect yourself, you need to disable
some types of Javascript and ActiveX controls in your
browser. See page 37 for directions on how to do this.
Not all adware is illegal: The licensing agreements
of some software programs allow the program to function
as adware. Carefully read the licensing agreements of
any program that you install on your computer, especially
free screensavers and demo games.
Spyware
Spyware is software that surreptitiously installs itself
on your computer, usually through dishonest means such
as a Trojan horse or an unsolicited file download through
your Web browser. Its function is to monitor and log
system activity. Some spyware programs record every
key a user types, then store that information on the
hard drive of a computer. The spyware creator can then
access and scan that information for passwords, bank
account numbers, SIN numbers and other confidential
information or client data. In other words, spyware
makes your computer vulnerable to hacking, fraud and
identity theft.
Recognizing and avoiding spyware and adware
Is your computer acting strangely? Is it running very
slowly? Is there unexplained hard drive activity or
Web traffic when you are not actively using it? Was
your browser home page changed? If so, you may have
a virus, spyware or other sort of malware on your computer.
Adware and spyware can be extremely difficult to remove
from a computer.
Because current antivirus software has only basic functionality
to protect you from adware and spyware, you should use
products specifically designed for this purpose. Two
good products to consider are Ad-Aware (www.lavasoftusa.com)
and Spybot S&D (http://security.kolla.de).
They are easy to download and install, and should be
used together as they will each catch things the other
will miss.
The free personal version of Ad-Aware may not be used
on business computers. For maximum protection, run Ad-aware
and Spybot every week or two, and, update them regularly.
Unfortunately, you’ll have to check the products’
Web sites regularly for updates, as they don’t
include an automatic update feature.
