To take action before IT security attacks become critical, organizations need the analytics capabilities necessary to identify anomalous and suspicious behavior quickly.Our Anomalous Behavior Detection Solution addresses security issues that conventional methods can’t. It can help to detect and prevent theft of data or intellectual property (IP), for instance at the behest of nation states, organized crime, or by a disenchanted employee. It can quickly identify when a user is behaving in a way that is abnormal for them and take appropriate action to limit what they can do, or flag up the situation for managerial attention. It can also predict when anomalous behavior is likely to occur, flagging events of interest for further investigation for potential security breach.

 Foreign States
 Hactivists
Utilities: Disrupt as a

Financial Services:

Intellectual Property
Traditional Security approaches wouldn’t catch Edward Snowden and can’t adapt quickly enough to
new cyber-crime attacks.

Three drivers have increased the attack surface:
Data volumes, variety and velocity are increasing

Clouds add complexity
Blurred boundaries: Increased need to share data/information
across the business and with 3rd parties

A new approach is needed to counter the threats

Increased Threats
Traditional tools don’t
protect against “bad
actors” who target IP,
financial Information and
strategic access.
Our approach creates
insight into anomalous
behavior and threats within
the business and
surrounding ecosystem.
Allows you to take
appropriate action based
on potential impact of
threat to reduce risk.

SIEM and GRC could not prevent Mr. Snowden
 Right identity & access controls

 Social engineering has been a primary
attack vector for large threats
 Significant IP breaches are often socially
engineered
 Current tooling is important but
insufficient:
• Governance, risk and compliance (GRC)
defines a set of “allowed behavior”
• Identity and access management tooling
provide the system level access controls
based on policy
• SIEM collates but does not provide insight or
analytics in the right ways to identify these
threats.

Edward Snowden:
 In role
 Logs collated his activity
 Yet the assets were accessed
 The NSA could not spot the anomalous
behavior.

We need a different approach
Anomalous Behavior
 Traditional approaches need to be
complemented – SIEM, GRC are still needed
 GRC says what is approved – the tasks you
can do, the gates you can go through.
Abnormal Behavior Detection says whether
you should have.
 Extend using Anomalous Behavior Detection:
 This approach:
1. Learns what is normal [the difference between
approved and allowed]
2. Identifies what is anomalous and categorizes
the risk
3. Alerts so you can react before it becomes a
problem.
New Outcomes are Possible
 It is an extension of current security
approaches that enables a reduction in GRC
and can identify threats that GRC cannot
• It shows where “allowed” is not “normal”
and the scope of the deviation from the
norm.
• Detect social engineering attacks as well as
network level detections
• Minimize the exposure time and loss
• Potentially predict the leakage areas ahead
of the attack
• This can be applied to both GRC areas
(Snowden) and non-GRC areas (networks,
non-controlled information) to build up a
broader pattern of behavior.

Typical Use Cases
 Visualizing heat maps of issues across an organization by business unit
or profile
 Profiling systems or devices for indicators of risk, highlighting places where an
alert needs to prioritized over others because of its likelihood of affecting the
business
 Spotting a compromised host when a particular IP address or user exhibits
multiple suspicious characteristics over a week-long period
 Providing investigative context after an alert gets triggered to determine the
cause or impact of an issue, e.g. if the user downloaded an executable prior to
the alert, or the IP accessed a critical asset after triggering the alert
 Detecting lateral movement based on active data by using graph analytics to
profile user behavior and peers’ behaviors.
