agenda
Agenda
  • A few basics
  • What do we mean by risk?
  • What’s special about e-Commerce risks?
  • Approaches to managing certain components of risk
  • Questions
what is e commerce
What is e-Commerce?
  • Internet-enabled commerce
  • ‘Sexy’ - but dangerous
    • Inward risks - hacking, denial of service
    • Outward risks - unauthorised disclosure of private information and IP
  • Global network of computer networks (Comparable to the telephone network)
  • No owner or single administrative body
types of e commerce 1
Types of e-Commerce - 1
  • Business to Business (B2B)
    • Internet enabled relationships with business partners, customers, suppliers (extranets)
  • Business to Consumer (B2C)
    • Relationships with individual customers/end-users
  • Intra-Business (Intra-B)
    • Relationships within or between internal businesses/functional areas
types of e commerce 2
Types of e-Commerce - 2
  • Customer to Business (C2B)
    • “Reverse” market, where customer dictates product/service and terms of delivery (Priceline)
  • Customer to Customer (C2C)
    • Consumers interacting directly to create spot markets (eBay)
typical stages of e commerce
Typical stages of e-Commerce
  • Stage: 1 - establishing an Internet and e-Commerce presence through e-mail
  • Stage: 2 - establishing a visual e-Commerce presence with a pre-sale and post-sale web site
  • Stage: 3 - on-line order entry
  • Stage: 4 - internal integration of web based e-Commerce activities and “back office” functions
  • Stage: 5 - external integration of seller and buyer networks to allow automated supply-chain management
  • Stage: 6 - complete integration of technology including core technologies
what is risk
What is risk?

“The exposure to the possibility of such things as economic or financial loss or gain, physical damage, injury or delay, as a consequence of pursuing a particular course of action.”

general risks
General risks
  • Some unique general risks present themselves:
    • Possible loss of public confidence (if control failures are publicised)
    • Failure to comply with legal and regulatory requirements (possibly in multiple jurisdictions)
    • Erosion of traditional control mechanisms (loss of ‘common sense’ and compensating controls)
    • Technical complexity of infrastructure and systems
    • High reliance on third-parties (Trust)
specific risks
Specific risks
  • Specific e-Commerce risks are many and varied. It is convenient to group them as follows:
    • Strategic risks
    • Project and operational risks
    • Infrastructure risks
strategic risks
Strategic risks
  • Risks to the e-Commerce initiative due to the overall strategy/plan
    • E-Commerce strategy itself
    • Senior management support
    • Competing organisational priorities
    • Legal and regulatory issues
    • Invalid assumptions
project operational risks
Project/operational risks
  • Risks due to the implementation project itself, IT operations, and routine use of the system
    • Financial and human resources
    • In-house expertise
    • Outsource partners
    • Stakeholders
    • Support processes
    • Monitoring
infrastructure risks
Infrastructure risks
  • Risks due to the underlying application and technical (hardware and network) infrastructures
    • The technical infrastructure
    • Security over the technical infrastructure
    • System availability/reliability
    • Application security controls
    • Application processing controls
    • Interfaces with other systems
what and where is the risk
What and where is the risk?
  • What is the approach to managing strategic risk?
  • What is the approach to managing project risk?
  • What is the approach to managing information and technology risk?
assessing the risk
Assessing the risk
  • E-Commerce strategy relative to overall business goals
  • E-Commerce program management
  • Operations management
  • Application infrastructure
  • Technology infrastructure

Threats
traditionally
Traditionally
  • People actively in the loop - policy enforcement
  • Physical isolation of information
  • Restricted logical access
  • Business hours
e commerce environment

INTERNET

E-Commerce environment
  • Protection policy enforced by machine
    • You can talk to a person, you must program a machine
    • Machines have a hard time with discretion
  • Any time, any where, service expectation
  • Millions of potential customers or clients
  • Different employee to customer ratios and skill sets
objectives
Objectives
  • Making sure the data is not altered as it passes between one end point and another
    • The use of signatures to ensure the data stream is not altered
  • Making sure you know who it is you're talking to at the other end
    • Authentication to verify the remote user
  • Preventing unauthorised third parties from eavesdropping on your conversation
    • Encryption to prevent eavesdropping
traditional security mechanisms
Traditional security mechanisms
  • Confidentiality -
    • Locked file cabinets, drawers, safes, envelopes, personnel, service counters
  • Integrity
    • Product seals, shrink-wrap, signatures, barcodes
  • Availability
    • Multiple locations, personnel, alternate delivery options
  • Non-repudiation
    • Signatures, confirmations, receipts
e commerce mechanisms
E-Commerce mechanisms
  • Confidentiality
    • Data encryption, automated access controls, access control lists, passwords, tokens, biometrics
  • Integrity
    • Digital signatures, permissions, hash algorithms, audit trails
  • Availability
    • System redundancies, back-ups, off-site storage, hot/cold recovery sites, fail-over
  • Non-repudiation
    • Audit trails and logs, digital signatures and certificates
encryption
Encryption
  • Plaintext to ciphertext
  • Renders message unreadable
  • Secret key method - same key to encrypts and decrypts
  • Public key method - two keys, one kept secret and never transmitted, and the other made public. (Public key method is used to safely send the secret key to the recipient so that the message can be encrypted using the faster secret key algorithm).
