Agenda • The Internet • Traditional Security Practices & Perceptions • The New Enterprise • Security Plan • Online Business Risks • Protections of Assets/ PKI • Managed Security Services • Q&A
The Internet… • An efficient means of distributing information, products & services. • Offers excellent productivity gains to organizations. • Results in improvement of bottom line. • Ideal platform for global commerce. • …Is no longer incidental but integral to businesses.
BUT!!! • The Internet’s fundamental strength is also its most profound inherent weakness • Designed to facilitate information-sharing • Designed as a messaging infrastructure • Not secure from exploitation of traditional vulnerabilities • The most critical challenge posed is “SECURITY”
Traditional Security Practices & Perceptions (1) • Driven by “one-size-fits-all” strategies • Follows piece-mealing enterprise security solutions • Firewalls • VPNs • Card Keys • Limit outside access to internal resources and systems • Browser based encryption (SSL) and username / password based authentication schemes
Traditional Security Practices & Perceptions (2) • Security is all about deploying firewalls • It is not for our business yet • Good security implementation is expensive • Security implementation has no Return on Investment (ROI) • Someone in the technical department will take care of security implementation

YESTERDAY TODAY Internal Focus Access is granted to employees only External Focus Suppliers, Customers, and prospects all need some form of access Centralized Assets Applications and data are centralized in fortified IT bunkers Distributed Assets Applications and data are distributed across servers, locations, and business units Prevent Losses The goal of security is to protect against confidentiality breeches Generate Revenue The goal of security is to enable E-commerce IT Control Security manager decides who gets access Business Control Business units want the authority to grant access Forrester Research, Inc.
Common Security Issues • Eavesdropping (Confidentiality) Information remains intact, but privacy is compromised. • Tampering (Integrity) Information in transit is changed or replaced. • Impersonation (Authenticity/ Non-repudiation) Spoofing: A person pretending to be someone else. Misrepresentation: A person or organization misrepresenting itself. • Availability System operations are disrupted and service is denied.
Security Plan Establish a security plan/ policy that considers: • Business strategy and objectives • Identification of threats/vulnerabilities and management of risks • Protection of critical assets & systems • Elevating security awareness company-wide • Continuous monitoring & evaluation of security controls
Online Business Risks • Determinants of risk: Online assets, vulnerabilities & threats • Assets at risk: Equipment, data, business reputation • Risk profiling: Assessing risk sensitivity level of assets

Public Key Infrastructure (PKI) • Supports trusted interactions. • Provides authentication, confidentiality, non-repudiation, integrity and access control assurances • Enables encryption & decryption of online transactions • Digital certificates & digital signatures for users & businesses • Trusted certification authority role
