Personal documents and data are an identify thief’s dream…their ticket to
accessing financial accounts, applying for loans and credit cards, and
other credit-destroying behavior. Take this a step further to include tax
documentation, and now you’ve got a one-stop shop for social security
numbers, employer and financial information, addresses, and employer
identification numbers.
It’s personally identifiable information to the extreme. The fact is that
scammers are always “on” and looking for ways to snatch sensitive
information in order to wipe out bank accounts, receive medical care, and
steal identities—the big take. And while fraudsters are enjoying a
financial heyday, it’s your clients who will get the bills.
With so much personal information online, the probability of data theft
these days is extremely high. As such, it’s critical that accounting
professionals understand the risk and how to protect their firms and their
clients. With a little insight into best practices for your firm and your
clients, you can avoid the world of hurt and anxiety that comes with having
sensitive information compromised.
Common data-compromising positions
There are so many ways scammers can get to data. Being aware of these
tricks is the first step in protecting your firm and your clients.
Social engineering: This is an all-too-common method that tricks
individuals into giving out personal information. In fact, this method is
so effective that it boasts an 80% success rate. Common scams include a
phone call from “customer service” or an onsite visit from someone claiming
to represent a company or agency and requesting personal information to
solve a fictional issue. And no agency is safe from impersonation; just
consider the sophisticated phone scam of 2014, where crooks posed as IRS
agents demanding tax payments.
Phishing: This is simply the digital equivalent of social engineering where
scammers impersonate a company or well-known agency online. Victims often
receive an official looking email asking for their personal information or
are invited to click a link that leads to a phony website designed to
capture personal data.
Physical access/shoulder surfing: This is exactly what it sounds like. If
scammers can access your hard copy documents or your computer, then they
can easily get to your personal information. Don’t be surprised either if
your information is stolen by someone simply looking over your shoulder and
surfing your device’s screen. Scammers have even been known to use mirrors
to read computer screens with their backs turned to the victims. All too
often, individuals get lost in their technology and forget that their data
is exposed.
Expired access: Many businesses forget to remove former employees or
contractors from their systems after these folks depart, opening the door
to data theft. The fact is that most system hacks are inside jobs,
performed by former and/or disgruntled employees.
Dumpster diving: Believe it or not, people still throw out fully intact
documents and devices that house personal information, like credit card
statements or hard drives. Scammers are not above getting their hands dirty
(literally) to uncover sensitive information.
Vulnerable machines and networks: Unprotected machines and networks are
sitting ducks for attackers—for example, machines with outdated operating
systems or expired antivirus software and networks that are unsecure and
wide open, such as public WiFi. Security weaknesses are bait for scammers
at the ready to track key strokes, capture unencrypted data, and flog users
with ransomware.
Data-protecting tips
For all the scams identified above, there are basic tips that help bar
attackers from infiltrating your firm. This information is also gold in
supporting ongoing education for clients.
Outsmart the social engineers and phishers: The basic rule is to never give
sensitive information to anyone just because they ask. Legitimate inquires
most often will come via mail, and rarely by phone or through email.
Challenge inquiries by asking requestors to verify their identity and then
direct them to send the request via mail.
Secure your physical fortress: You heighten the security of both hard and
electronic documents and data by simply limiting access. Enforce strict
onsite visitor policies (require badges and sign-in), lock file cabinets
and encrypt documents, secure computers with complex passwords (and change
your passwords regularly), and install privacy screens on all devices.
Eliminate expired “goods”: We throw out expired milk for fear of the
nauseating physical consequences, so why do we put our personal data at
risk by maintaining logins for expired staff? The consequences are just as
nauseating. Avoid the data-theft plague by establishing a structured
security policy. Strictly enforce rules for who has access to what
information, and adhere to the “principle of least privilege”—give the
minimum access required to perform the job. Also, be sure to discontinue
system access immediately after an employee, contractor, or vendor no
longer requires it.
Clean out your dumpster: Keep scammers out of your physical and digital
dumpsters by destroying information up front. Shred paper docs and wipe all
media including disks, drives, and other devices.
“De-vulnerablize” your machines and networks: For machines, keep your
operating system and apps up-to-date. Use a firewall and current antivirus
software and choose complex passwords. In relation to networks, avoid
joining random public hotspots, and use a VPN to connect to your firm and
SSL to connect to the internet. Also avoid emailing sensitive data and use
a secure portal instead.
Proceed with caution
While many of these data-protection tips seem common sense, it’s surprising
how many people do not employ them. The consequences of being hacked can be
devastating to both your firm and your clients, so take heed and proceed
with caution by applying these tips, while also reviewing the IRS guide,
“Safeguarding Taxpayer Data” (https://www.irs.gov/pub/irs-pdf/p4557.pdf).
Avoid the “Big Take” by shutting down attackers before they infiltrate.
