Impact on Confidentiality due to
Insider Attacks
Project Part 3
Submitted by the Team: AVATAR
(Jonathon Raclaw, Marek Jakubik, Rajesh Augustine, and Rao Pathangi)

? Impact on Confidentiality due to Insider Attacks
? An insider is anyone with access to an organization's protected
assets
? Insider attack is someone using that access to violate protocol
or cause harm intentionally or unintentionally
? Protocol violations with good intentions are still considered
threats
? We have already identified a variety of fields that have
vulnerabilities due to Insider Attacks
? A Telecommunications Company and it��s employees having
default access to sensitive test data
? A Credit Card Company and it��s employees having access to
customer credit card numbers
? A Health Care Company and the diverse collection of
people/employees that have access to user health data [2]
Introduction and Background

? There are four basic sources of insider security
problems:
?Maliciousness �C that results in compromise or destruction of
information, or disruption of services to other insiders
?Disdain of Security Practices �C that results in compromise or
destruction of information, or disruption of services to other
insiders.
?Carelessness �C in the use of an information system and/or the
protection of company information
?Ignorance �C of security policy, security practices and
information system use
? Current state of work:
?Basic User ID/ password validation �C missing role based
access, department based access. If you know the User ID/
Password then you have pretty much every thing
?Policy and procedures �C Not strictly enforced [3]

? Develop stronger authentication
mechanisms �C Some apps do have generic
User ID/ Password
? Implement role based access control �C
Provide just what they are eligible to see
? Provide access to the information based on
their department��s business need �C Provide
just what they need
? Enforce the security policy �C tie the
violations to job performance
[5]

? Purchase Hitachi ID Identity Manager �C To better manage
user access identities and privileges on a variety of IT systems
? Hitachi ID Identity Manager �C A complete user provisioning
solution that also automates and simplifies the routine tasks of
managing users across multiple systems
? Features provided by Hitachi ID Identity Manager
? Provides the Role Based Access Control (RBAC)
? Enables prompt and complete access deactivation across multiple
systems
? Automatically deactivates access for terminated users
? Enforces authorization rules over security change requests
? Existing work
? No Role Based Access Control �C If you know User ID/ Password
then you are good to go
? No centralized control of access control
? Each system has it��s own way of authenticating users, some with
no authentication!!!

Architectural view of Hitachi ID Integration
[1]

? Cost Analysis �C Following example gives a cost savings example for an
organization with 10,000 people per year
Benefits:
? With 10% turnover, 5 day for manual setup, 1 day for automatic setup - $60,000
per year productivity
? With 1 change per user per year �C wait time is reduced from 4 hr to 1 hr
? 8 administrative FTEs reduced to 4
? Risks
? Additional cost �C Cost to acquire, setup cost, maintenance cost
? Inherent risks of a new IT system
? Need of experts of Hitachi ID
Item Current
Cost
Reduced Cost
Productivity lost by new users waiting for access $1,200,000 $240,000
Productivity lost by current users waiting for
changes
$1,200,000 $300,000
Direct cost of security administration $480,000 $240,000
Total $2,880,000 $780,000
Total savings per year $2,100,000

? Suited for large companies �C Large companies where we have
many systems and large number of employees
? Build vs. Buy �C Building Custom solution would be more costly
and may not produce an effective security solution, so go for a
ready made solution
? Enterprise wide solution �C This strategy is to be adopted by
the IT and other users of the company��s resources such as
contractors, visitors, etc
? Incremental Deployment �C Is it incrementally deployable and
would not require a require complete tear-down.
? Cost �C Cost is an obstacle but security needs to be implemented
and enforced
? Lack of expertise �C Most of the companies lack expertise in
building security solutions, so trust the leader in the field

? Benefits of Hitachi ID versus Sun Identity Server
? More platform-neutral solution for their IDM products
as opposed to Sun that is tied to Oracle
? Recognized by industry as more scalable and reliable
? Integrates equally well with all the major databases,
operating systems, web servers and ERP applications
? User provisioning is open to allow easy integration
? Lower lifetime support costs for deployed systems
since the customer has a stronger bargaining position
at maintenance renewal time, since replacing one
product is much easier than replacing many. [1]

A basic tenet of legal liability should compel a company
to address security issues and to eliminate or mitigate
hazardous conditions promptly.
? Business:
? No lost revenue due to malicious activities
? Reputation is maintained/ increased by reducing the information
breaches and fraud
? Increased user productivity by automating and centralizing the access
control
? Cost savings in a longer run
? Safeguard of the confidential information
? Legal:
? Regulatory Compliance such as Sarbanes-Oxley, HIPAA
? Avoid regulatory penalties for non compliance
? Avoid Lawsuits by customers for information leakage

? With the Hitachi ID solution in place, we could more
easily limit access to certain tools, such as make only
development and test teams have access to test
tools. Thus reducing the temptation of insider attacks
by parties that are outside of the target environment.
? As the Hitachi implementation would work with the
existing employee grade and position matrix, the Role
Based Access Control (RBAC) could be targeted and
changed easily if there is a restructure effort from
management.
? Easy monitor of access to telecom systems,
provisioning data, customer data, technical and
product development data
Fit of Proposed Solution for Telecom sector

? Complex nature of business with several
applications need a centralized control
? Cost savings by using Hitachi ID product does
makes business sense
? Access for Customer Service Agents
?Role based, Example: regular agents,
supervisors
?Based on their department, Example:
marketing, collections, product sales
? Access to Intranet Applications �C Based on
roles, Example: employee, manager, director
? Access to specific functionalities within a
Application �C Based on roles, Example: in the
time entry tool managers to see their staff
information

? Large number of applications for a educational
setup
? Constant need of creating and removing the
access for students
? Hitachi ID enables to propagate the password
changes to multiple applications
? Access to Intranet Applications �C Based on
roles, Example: student, professor
? Access to specific functionalities within a
Application �C Based on roles
Example: for teaching aid apps such as black
board, professors to have more access than
student

? Network Observable User Actions (ELICIT): Model data flow patterns relating to
searching, browsing, downloading, printing, sensitive search terms, printer choice,

? Honeypots: Systems deliberately placed in the infrastructure to weed out malicious
insiders.
? Future Research:
? Develop profile models that reveal ��user intent�� as opposed to ��user activity.��
? Develop integrated systems that follow the ELICIT model.
? Develop systems that preserve privacy in the event of a false positive
? Intelligent challenge/response model based on suspicion of anamalous activity
? ��Trap the traitor�� solutions (IT + Psychology)
