What is the market saying?
security
becomes
an
“enabler”
by
making
it
possible
to
bring
together
huge
stores
of
data
You
want
security
to
be
just
as
scalable,
high-­‐
performance
and
self-­‐organizing
as
the
clusters
most
big
data
technologies
don’t
have
any
security
features
built
in
want
fine-­‐grained
security
and
policy
control
at
the
database-­‐level

• With
every
copy
of
data,
there
is
an
increased
risk
of
unintended
disclosure
• Every
now
and
then
people
with
access
and
privileges
take
a
look
at
records
without
a
legiCmate
business
purpose
e.g.,
an
employee
of
a
banking
system
looking
up
their
neighbor
A few more risks…

So
what
can
we
do?

9. 9
Sqrrl Data, Inc., All Rights Reserved
(Def.)
A
form
of
security
in
which
data
carries
with
it
the
elements
of
provenance
that
are
required
to
make
policy
decisions
on
its
visibility:
• Separate
data
modeling
for
security
and
analysis
• Data
comes
with
security
aYributes
governing
its
visibility…..data
is
self-­‐describing
• Reusability
of
applicaCons
across
security
domains
• Distributed
development
of
ingest
and
query
applicaCons
• Supported
by
Accumulo’s
cell-­‐level
security

Data-­‐centric
security
approach
allows
all
the
data
to
be
stored
on
a
single
pla9orm
and
only
authorized
data
is
returned
to
the
user
Pushing
security
to
the

simplifies

enables
more

We
now
have
user
access
to
the

secured.
But
what
about
your

By
encrypCng
the
files
we
write
into
HDFS
we
further
eliminate

the
