ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data LakeWalaa Eldin Moustafa
Dynamic policy enforcement is becoming an increasingly important topic in today’s world where data privacy and compliance is a top priority for companies, individuals, and regulators alike. In these slides, we discuss how LinkedIn implements a powerful dynamic policy enforcement engine, called ViewShift, and integrates it within its data lake. We show the query engine architecture and how catalog implementations can automatically route table resolutions to compliance-enforcing SQL views. Such views have a set of very interesting properties: (1) They are auto-generated from declarative data annotations. (2) They respect user-level consent and preferences (3) They are context-aware, encoding a different set of transformations for different use cases (4) They are portable; while the SQL logic is only implemented in one SQL dialect, it is accessible in all engines.

examination and analysis of data held on,
or retrieved from, computer storage
media in such a way that the information
can be used as evidence in a court of law.

Computer Forensic Activities
Computer forensics activities commonly include:
– the secure collection of computer data
– the identification of suspect data
– the examination of suspect data to determine details
such as origin and content
– the presentation of computer-based information to
courts of law
– the application of a country's laws to computer
practice.

The 3 As
The basic methodology consists of the 3
As:
– Acquire the evidence without altering or
damaging the original
– Authenticate the image
– Analyze the data without modifying it

Computer Forensics - History
1984 FBI Computer Analysis and Response Team
(CART)
1991 International Law Enforcement meeting to
discuss computer forensics & the need for
standardized approach
1997 Scientific Working Group on Digital Evidence
(SWGDE) established to develop standards
2001 Digital Forensic Research Workshop (DFRWS)
development of research roadmap
2003 Still no standards developed or corpus of
knowledge (CK)

Fit with Information Assurance
Computer Forensics is part of the incident
response (IR) capability
Forensic “friendly” procedures & processes
Proper evidence management and handling
IR is an integral part of IA

(PDCAERF)
Preparation
– Being ready to respond
– Procedures & policies
– Resources & CSIRT creation
– Current vulnerabilities & counter-measures
Detection/Notification
– Determining if an incident or attempt has been made
– IDS
– Initial actions/reactions
– Determining the scope
– Reporting process
29. 29
(PDCAERF)
Containment
– Limit the extent of an attack
– Mitigate the potential damage & loss
– Containment strategies
Analysis & Tracking
– How the incident occurred
– More in-depth analysis of the event
– Tracing the incident back to its source
30. 30
(PDCAERF)
Eradication/ Repair-Recovery
– Recovering systems
– Getting rid of the causes of the incident,
vulnerabilities or the residue (rootkits, trojan
horses etc.)
– Hardening systems
– Dealing with patches

Challenges
Eric Holder, Deputy Attorney General of the United States
Subcommittee on Crime of the House Committee on the
Judiciary and the Subcommittee on Criminal Oversight of
the Senate Committee on the Judiciary:
Technical challenges that hinder law enforcement’s ability to
find and prosecute criminals operating online;
Legal challenges resulting from laws and legal tools needed
to investigate cybercrime lagging behind technological,
structural, social changes; and
Resource challenges to ensure we have satisfied critical
investigative and prosecutorial needs at all levels of
government.
33. 33
Challenges
NIJ 2001 Study
There is near-term window of opportunity for law enforcement
to gain a foothold in containing electronic crimes.
Most State and local law enforcement agencies report that
they lack adequate training, equipment and staff to meet their
present and future needs to combat electronic crime.
Greater awareness of electronic crime should be promoted for
all stakeholders, including prosecutors, judges, academia,
industry, and the general public.
34. 34
General Challenges
Computer forensics is in its infancy
Different from other forensic sciences as the media that
is examined and the tools/techniques for the examiner
are products of a market-driven private sector
No real basic theoretical background upon which to
conduct empirical hypothesis testing
No true professional designations
Proper training
At least 3 different “communities” with different
demands
Still more of a “folk art” than a true science
35. 35
Legal Challenges
Status as scientific evidence??
Criteria for admissibility of novel scientific evidence (Daubert
v. Merrell)
– Whether the theory or technique has been reliably tested;
– Whether the theory or technique has been subject to peer review
and publication;
– What is the known or potential rate of error of the method used;
and
– Whether the theory or method has been generally accepted by the
scientific community.
Kumho Tire extended the criteria to technical knowledge
36. 36
Specific Challenges
No International Definitions of Computer Crime
No International agreements on extraditions
Multitude of OS platforms and filesystems
Incredibly large storage capacity
– 100 Gig Plus
– Terabytes
– SANs
37. 37
Specific Challenges
Small footprint storage devices
– Compact flash
– Memory sticks
– Thumb drives
– Secure digital
Networked environments
RAID systems
Grid computing
Embedded processors
Other??

Summary
DFS is a sub-discipline of criminalistics
DFS is a relatively new science
3 Communities
– Legal, Military, Private Sector/Academic
DFS is primarily investigative in nature
DFS is made up of
– Media Analysis
– Code Analysis
– Network Analysis
41. 41
Summary
Computer Forensics is a sub-discipline within DFS
Computer Forensics is part of an IR capability
3 A’s of the Computer Forensic Methodology
There are many general and specific challenges
There is a lack of basic research in this area
Both DFS and Computer Forensics are immature
emerging areas
