Pro-logos

• At the beginning there was light
• then the cosmos
• then all the species
• and finally there was WAR!!!

Threat Assessment

• A threat assessment is a statement of threats
  that are related to vulnerabilities, an
  organisations assets, and threat agents, and
  also a statement of the believed capabilities
  that those threat agents possess.
• Threat f (Motivation, Capability, Opportunity,
  Impact)

4
Motivation

• Motivation is the degree to which a threat agent
  is prepared to implement a threat.
• The motivational factors are the elements that
  drive a threat agent to consider attacking a
  computer system
• political, secular,
• personal gain,
• religious, revenge,
• power, terrorism,
• and curiosity
• Q Can we deceive Them in believing that they do
  not want to target us?

5
Capability

• Capability is the degree to which a threat agent
  is able to implement a threat
• The availability of a number of tools and
  techniques to implement an attack, and the
  ability to use the tools and techniques
  correctly.
• The availability of education and training to
  support the correct use of various tools and
  techniques.
• The level of resource that a threat agent has, or
  can acquire over a certain time.
• Q Can we deceive Them in believing
• that they are not able to target us?

6
Opportunity

• The easiest of the 3 to manage?
• Opportunity can be defined as a favourable
  occasion for action.
• Past
• make sure that threat agents will be in no
  position of creating or exploiting opportunities.
  
• Present
• Risk is not managed by as but by the threat
  agents, so concentrate on Motivation

7
Threat Agents?

• The term threat agent is used to denote an
  individual or group that can manifest a threat.
• Hackers are good people!!!

Why do we analyse Them?

• It is a game, the aim achieve information
  superiority
• We need to understand what motivates them
• We need to know of their technical and
  educational capability
• We need to know how they think
• Security has to be proactive and not reactive

10
How do we analyse Them?

• We start by identifying them
• Threat agent catalogue
• Historical threat agent data
• Environmental reports
• Knowledge of personnel
• Stakeholder List

11
How do we analyse Them?
12
How do we analyse Them?

• Capability capability metrics available on
  request
• Opportunity
• Access to Information
• Changing Technologies
• Target Vulnerability
• Target profile
• Public Perception
• Motivation

13
InfoSec Requirements

• the activities to protect hardware, software
  and intangible information at the hardware and
  software levels (E. Waltz)
• Information has three abstractions data,
  information knowledge
• When threat agents acquire knowledge then they
  are able to launch active attacks with high
  probability of success.
• Q How do we ensure information superiority?

IO Taxonomy
IO Layer IO Layer Function NETWAR
Offence Perceptual Manage perception, Disrupt decision processes PSYOPS, Deception
Offence Information Dominate information infrastructure NETOPS
Offence Physical Break things, Incapacitate/kill people Physical destruction
Defence Perceptual Protect perceptions and decision-making processes Intelligence, Counterintelligence
Defence Information Protect information infrastructure INFOSEC
Defence Physical Protect operations, protect people OPSEC
15
What do we do!!!

• Could we possibly deceive threat agents?
• Through deception we can manage our adversarys
  perception and disrupt his decision-making
  processes.
• The outcome can be twofold
• either the defenders have time to react and
  deploy the necessary countermeasures (or finely
  tune the existing ones),
• or the threat agent will call off the attack and
  return to the information gathering process in
  order to re-examine his plan of action.

16
Is there a limit?

• Facts
• Infrastructures follow a certain logic which
  allows threat agents to easily enumerate them
• Administrators introduce vulnerabilities to their
  system in order to make their lives easier
• The users of a system are its biggest
  vulnerability
• Argument
• Can we use deception techniques on our own users?

17
Security through Deception

• Actions executed to deliberately mislead
  adversary military decision makers as to friendly
  military capabilities, intentions, and
  operations, thereby causing the adversary to take
  specific actions that will contribute to the
  accomplishment of the friendly mission
• Deception can be used in two ways for ensuring
  security
• Simulating showing the false, drawing attention
  away from the real
• Dissimulating hiding the real, producing
  confusion about what is real

18
Technical Solution

• G4DS system that brings enterprises together in
  virtual communities in order to identify and
  monitor threat agents
• Virtual Honeypots system that takes input from
  G4DS in order to perform near real-time threat
  agent deception

19
Deception Methodology

• Everything should be dedicated to the execution
  of the deception
• Intelligence must be brought fully into the
  picture
• Intelligence must be assessed
• Secrecy must be enforced
• The deception plan must be designed at the top
  levels
• Full implementation consistency of all elements
  of deception
• Deception must be continuous

20
Epi-logos

• Need to move reference point from risk assessment
  to threat assessment
• Need to be able to identify and monitor threat
  agents
• Hackers are good people!!!
• G4DS system that brings enterprises together in
  virtual communities in order to identify and
  monitor threat agents
• Virtual Honeypots system that takes input from
  G4DS in order to perform near real-time threat
  agent deception
