Protecting Corporate Data
There was a time when the
biggest privacy concern an employee had was someone reading over
their shoulder. But as companies rely ever more on IT systems that
enable workers to communicate and collaborate with clients and
corporate peers anywhere in the world, the chances of a hacker
compromising those systems increases exponentially. Unfortunately,
there is no single magic security bullet. Ensuring company security
is now a multi-faceted strategy that falls under an organization’s
overall IT security infrastructure.
Information of all kinds can be found in the corporate work place
these days:
Employers need to make sure all three areas are protected from
hacking or theft. The best approach is a combination of software
solutions and employee education.
Network Access Protection
A number of different
developers and manufacturers have developed technology solutions in
an area known as Network Access Protection (NAP). The idea behind NAP
is basic: to protect business computers from malware and to ensure
that they minimally comply with organizational standards before they
can access shared network resources; in other words, to keep out
external enemies without restricting an employee’s ability to
conduct business.
While your employees may be using state of the art programs and
operating systems on their work PCs, they may need to remote access
from other locations.. The world is full of home or remote computers
teeming with spyware or other backdoor threats that can at best
access and at worst steal all kinds of personal or work-related
information. NAP systems try to ensure that this unwanted software
stays off any machine accessing corporate resources.
NAP works by acting as a kind of cyber insurance. It enables a
company to define an outside computer’s “health” requirements,
such as running up-to-date operating systems. Once the list of health
requirements is set, NAP prevents access to any computer not in
compliance.
While handy and a good first line defense, NAP does not stop
hackers – if a hacker’s computer meets the health requirements,
it is allowed access. So other second and third line defenses are
necessary. Among the most common are firewalls, which act as security
sentries, only allowing authorized data to pass through, and
intrusion-detection and intrusion prevention systems, which look for
the telltale “signatures” of malware and block it.
Other valuable security measures include:
Anti-virus software
Enforcing a company-wide security
policy that includes employee education
Regularly updating Operating
Systems to keep security patches up-to-date
Limiting employee rights and
permissions to install software on their own PCs
Limit network services and only
install essential features that will be updated regularly
Limit employees to software directly used in their jobs
Having a knowledgeable and vigilant work force is another key to
business security. Rather than burying employees under a barrage of
rules and regulations, sometimes the most basic practices can be the
most valuable.
First and foremost is to stress the importance of not giving out
passwords and user names – to anyone. Explain how sharing company
passwords and usernames is the corporate version of handing out a
bank account number or debit card code to a handful of friends – it
is inviting theft.
Some companies have policies that require employees to change
their passwords monthly.
However, there are IT security experts who think that while good
intentioned, the rule may be counter-productive. Constantly changing
passwords makes it more likely the employee will forget what the
latest password is. That leads to them writing the password down
somewhere, which creates an increased security risk.
The better solution is educating workers on how to create a super
secure password that they keep for an extended period.
The best passwords have:
A combination of letters and
numerals
At least 8 characters
Are NOT based on personal information such as a birthday or
anniversary date
A number of systems now support extremely long passwords. This
allows employees to use whole sentences for their passwords.
Passwords of this length are much more difficult to crack.
Employees also need to be educated on the important of limiting
the software on their computers and rarely-used features on the
software they do have. What sounds a bit Draconian is actually a
preventative measure – rarely used software and features are less
likely to be updated for security patches, thereby increasing overall
risk.
By developing, implementing, and enforcing a multi-tiered IT
security policy, you can protect company security without sacrificing
productivity or breaking the bank.
