A
pragmatic primer for protecting your most critical assets by David
Johnson.
For most businesses, government agencies,
institutions and other organisations, security can at times seem
like an overwhelmingly complex challenge. Threats to your data,
both real and perceived, loom from all angles. Hacker attacks,
disgruntled or dishonest employees, and competitive snooping are
just some of the concerns with respect to protecting proprietary
information.
Regulatory drivers are mounting, as well,
as an ever-growing list of legislation and new acronyms to contend
with. In Europe, the EU and individual countries have their own
regulations governing the privacy of information including, as
examples, the European Community Directives on human rights, electronic
commerce, data protection, and privacy and electronic communications
and the UK’s Data Protection Act. In the US, HIPAA, GLBA,
and “SOX” are just a few to contend with. On a worldwide
basis, the Basel II Capital Accord is front of mind for all internationally
active banks.
Faced with a long and growing list of international
regulations affecting IT security, compliance is viewed as one
of the top concerns for many executives. Some of these laws hold
organisations accountable for protecting the confidentiality of
consumer or patient information. Others require companies to provide
detailed and reliable documentation on financial decisions, transactions
and risk assessments. And new laws are being passed all the time.
Deciphering the regulatory alphabet
soup
Here is a quick primer on some of these regulations and what they
mean:
GLBA: Under the privacy provisions
of the US Gramm-Leach-Bliley Act (GLBA), also known as the Financial
Services Modernization Act of 1999, banks, credit card companies
and other financial institutions that provide financial products
or services to US consumers must ensure the security and confidentiality
of customer records and information. They must also protect against
any anticipated threats or hazards to the security or integrity
of these records and protect against unauthorised access or use.
HIPAA: The privacy provisions of
the Health Insurance Portability and Accountability Act of 1996
(HIPAA), took effect from April 14th, 2003. It requires privacy
protection of medical records and other personal health information
created or maintained by health care providers who engage in certain
electronic transactions, health plans, hospitals, health insurers
and health care clearinghouses.
Sarbanes-Oxley (SOX): Most observers
would agree that the Sarbanes-Oxley Act (SOA) is the single most
important piece of legislation affecting corporate governance,
financial disclosure and the practice of public accounting since
the US securities laws of the early 1930s. What is more, section
302 forces Securities and Exchange Commission registered companies,
including many European organisations, to “evaluate the
effectiveness of internal controls over any information they issue
to capital markets”. This US law went into effect on July
30th, 2002. Initially, companies had to be in compliance by late
2003, but extensions were granted. Large corporations now have
until June 15th, 2004, to meet the requirements of Sarbanes-Oxley.
Smaller companies have to comply by April 15th, 2005.
Basel II: The Basel II Capital Accord
is an amended regulatory framework that has been developed by
the Bank of International Settlements that requires all internationally
active banks, at every tier within the banking group, to adopt
similar or consistent risk-management practices for tracking and
publicly reporting exposure to operational, credit and market
risks. It requires the identification of risks that a company
is exposed to, a report detailing the processes in place for identifying
and measuring future risk, and confirmation that sufficient cash
reserves are available to cover all risk exposure – capital
held must be closely matched to risks undertaken.
UK Data Protection Act: The Data
Protection Act 1998 came into force on March 1, 2000 and implements
the EC Directive. It applies to computerised personal data as
well as data held in structured manual files. There are eight
principles put in place by the DPA to make sure that sensitive
personal information is handled properly. They say that data must
be:
1. Fairly and lawfully processed;
2. Processed for limited purposes;
3. Adequate, relevant and not excessive;
4. Accurate;
5. Not kept for longer than is necessary;
6. Processed in line with the individual’s rights;
7. Secure; and,
8. Not transferred to countries without adequate protection.
Basic tenets for compliance
Unfortunately, there is no single “one size fits all”
implementation solution for complying with all the rules. But
there are some basic strategies companies can use that will help
them better deal with the security and retention of electronic
data and lay a proper foundation for building their own framework
to help comply with these regulations – and to protect proprietary
business information.
If one were to break down the basic building
blocks for building a security foundation, they would certainly
include these basic security elements:
* A sound security policy – establishing
the proper procedures and processes for how employees and systems
should handle sensitive information.
* Proportionate to the threat – security is a form of insurance
so make sure it is clearly targeted at protecting your most critical
assets from the most likely or most damaging risks.
* Data encryption – to protect the privacy of consumer,
patient, financial, or other sensitive information.
* Strong authentication and access controls – to ensure
that only the people with a proper “need to know”
have access to, or can change sensitive information.
* Data integrity checks – to ensure that the information
has not been altered
* Continuity of service – to ensure that operations are
not disrupted for any significant period of time.
And most importantly, establishing internal
awareness among your employees through education on your security
policies. The proper usage of security technology can go a long
way towards compliance.
Sound simple enough? In theory, yes. But in practice – not
always.
A visit to the security scrapheap
Organisations have expended enormous amounts of energy and money
to address these threats and drivers over the past few years –
often with very little in tangible results to show for it. Expensive
PKI projects and other security initiatives can remain perpetually
in pilot due to complexities of implementation, support and lack
of end-user acceptance.
And those that have been successful in deploying
sophisticated solutions within their organisations often find
themselves isolated on islands of security due to incompatible
technologies, infrastructures, and policies between themselves
and their external customers and business partners.
So all the hype about security solutions
– PGP, PKI, smart cards, biometrics, automated security
policy enforcement, client authentication, message security, VPNs,
access control – all too often remain hype. It really shouldn’t
be this difficult.
A pragmatic approach to security
According to Bruce Schneir, an internationally renowned security
technologist and author, “The more complex a security solution
is, the less likely it will be used”. Rather than throwing
money at the latest technology, a more pragmatic approach to protecting
information would start with determining what information your
organisation is trying to protect and how, assess the existing
and planned infrastructure within which the solution must operate,
and most importantly identify whom the users are – both
inside and outside the organisation – and their usage context.
More specifically:
* Does the information need to be protected in storage, in transit
or both?
* What computing systems will need to store, access or transfer
the information?
* Who are the users and owners of the information, and what applications
and processes will they be using to access and share it with others?
* Does the information need to be exchanged with external organisations
– i.e. business partners, customers, government agencies,
or other external constituents?
* What is the current and planned infrastructure within which
the information security solution must work?
* What resources are available, once the solution has been implemented,
for training end-users and providing ongoing support?
* Finally, what are the basic requirements for protecting information
– i.e. ensuring confidentiality, data integrity, non-repudiation,
authentication of author/sender as well as ensuring access by
only the intended recipients.
Typical requirements within an enterprise
setting might include:
* Minimal overhead and infrastructure requirements. Your security
shouldn’t require a huge investment in adding additional
bandwidth and storage. Incurring these significant costs up-front
makes it difficult to justify the ROI associated with security.
* Completely interoperable across organisations, platforms, applications,
and infrastructures. Your security solution needs to be completely
interoperable – not only within your company (where you
can control your users’ applications and computing platforms)
– but more importantly, it needs to work seamlessly with
your external partners, customers, consultants and other key constituents.
* Compatible with existing and future infrastructure investments.
You want to ensure that any security solution you deploy today
not only works within your existing infrastructure, but also your
future one. For example, perhaps your plan is to someday deploy
a PKI within your organisation and issue certificates to your
end-users or external partners. It’s important that whatever
you deploy today can support tomorrow’s direction as well.
* Simple and cost-effective to implement and support. It goes
without saying that whatever you deploy needs to be cost-effective,
easy to implement, and easy to support.
* Easy to use. And last, but not least, it needs to be easy to
use. Because if it’s not inherently simple for your end-users
to use – they won’t.
Moving from analysis to action
Once the information protection requirements are determined, the
next step is to then evaluate alternative approaches. Organisations
should consider a range of options – often the best solution
is one that may not have originally been considered. Based on
your own requirements, determine your selection criteria and use
these to evaluate vendors’ products as well as competing
technologies. A subset of these solutions may include messaging
security for protecting internal and external e-mail communications,
securing archived financial information, or protecting communications
between an organisation’s data centre and its branch offices.
Typical approaches for implementing these solutions include a
Public Key Infrastructure (PKI) and related technologies such
as S/MIME, Virtual Private Networks, PGP (“Pretty Good Privacy”),
and others.
A more recent entry into the security solution
mix is PKWARE’s SecureZIP™ technology. PKWARE, the
creator and continuing innovator of the widely used ZIP file format,
has integrated strong security into its multi-platform PKZIP products.
PKZIP combines the benefits of ZIP data compression – storage
and bandwidth efficiency, cross-platform interoperability, and
broad user adoption – with new strong encryption and digital
signature capabilities powered by RSA Security’s BSAFE software.
It works within both PKI and non-PKI environments, allowing users
and organisations to effectively “bridge the gap”
between those that have digital certificates and those that don’t.
PKWARE has also developed a free PKZIP Reader
product, which enables any recipient of a SecureZIP file to unzip,
decrypt, and even process digitally signed archives. With PKZIP
Reader, PKWARE is employing a strategy similar to that of Adobe’s
Acrobat Reader, which has enabled the pdf format to achieve broad
acceptance as the de facto standard for transporting documents.
PKZIP Reader is available to individual end-users from PKWARE’s
web site, or can be redistributed in a customised and co-branded
fashion by large organisations with its recently announced PKZIP
Reader Partner Program.
In summary:
There is no “silver bullet” for curing all your security
needs – whether they be regulatory compliance or otherwise.
But by taking a pragmatic approach to defining security requirements
and policies based on what you’re trying to achieve, considering
how your users (internal and external to your organisation) will
interoperate with the information and technology, and integration
with your current and future infrastructure – you can help
avoid the unnecessary time and expenses that have plagued many
organisations’ attempts at implementing “sophisticated”
security solutions.
