Identity and Access Assessment
Posted by Robbie Forkish on Fri, Sep 11, 2009
Deloitte reports that excessive access rights was the top audit finding for the most recent two years surveyed. Not only is it the top audit finding, but IDC states
that excessive access rights result in the biggest financial exposure
for organizations—and up to 60% of rights on most systems are expired
and therefore dormant. The problem is that IT and security staff at
most companies don’t know that this condition exists—or more precisely,
they suspect it exists but don’t know where.
Compounding the problem for these companies is that auditors have in
recent years learned that by spot-checking recent transfers and
terminations, they are more than likely to uncover excessive access
rights. This has contributed to the high rate of audit findings in
recent years.
Conventional wisdom holds that the solution to this issue is better
Identity Management (IdM) systems with role-based access control (RBAC)
capabilities and a user interface that can be understood by
line-of-business managers, who could then be counted on to keep access
rights current and accurate. Unfortunately LOB managers are often
reluctant partners in this enterprise; the path of least resistance for
them is to keep existing rights when in doubt. And the high rate of
audit findings suggests the weakness of this approach.
Whether companies have an IdM system or not, they most likely prepare for audits by manually
analyzing HR records and job descriptions in conjunction with role
definitions and entitlements. This quarterly or annual process is
invariably referred to by customers as a fire drill. In many cases,
contractors or temp workers are brought in for this task—adding to the
expense but rarely improving the outcome as measured by audit findings.
In the real world, access rights or entitlements are constantly
changing, for legitimate reasons: employees are hired and terminated;
contractors come and go; service providers and outsource firms require
access on a project basis with often unclear timelines; federated
identity management systems expand the concept of trusted user beyond
the enterprise boundary; departments and whole companies undergo
reorganizations; mergers and acquisitions result in major
restructurings; layoffs lead to rapid and sometime undocumented role
changes; and employees transferring within a company inevitably have to
overlap responsibilities (and access) between their old and new jobs.
Unclear and imperfect communications between HR, line-of-business
staff, and IT exacerbate the problem.
There is no perfect IdM system and there’s no foolproof rights
management process. Since the systems and processes for managing rights
inevitably fall short of 100% accuracy, some kind of feedback or
assessment mechanism is required to achieve least privilege objectives
and improve IT audit performance. That’s why Cloud Compliance
is developing the industry’s first Identity and Access Assessment
(IdAA) system—to provide feedback that identifies, reports on and helps
remediate excessive access rights and other access audit issues.
Cloud Compliance will address the IdAA challenge with a unique,
innovative SaaS solution. Our cloud-based analytics assesses log-based
access activity for selected applications, typically those that are
audited or that access sensitive data such as personal identifying
information (PII). We identify dormant (aka zombie) accounts, and
provide tools for isolating high rates of dormancy by group, business
unit or by application. Such tools enable root cause identification,
and provide the necessary insight for remediation and process
improvement. Furthermore, due to our global visibility as a
multi-tenant SaaS solution, we capture statistics industry-wide that
our customers can access for setting their own policy benchmarks.
Finally, in contrast to software-based IdM solutions, the Cloud
Compliance SaaS solution requires no software to install, maintain and
operate, no appliances to deploy, no consultants, advisors or
professional services to deploy, and no huge upfront capital expense to
incur.
Ronald Reagan famously said “Trust, but verify”. Many IdM systems
are trusted to maintain entitlement and access rights. But the systems
themselves rarely have verification capabilities. They would benefit
greatly from an Identity and Access Assessment solution that provided
verification, and in doing so improved audit performance and regulatory
compliance.
