  1. TESTA II Network Security June 06, 2000 Global One Communications Christian Sinephro email: christian.sinephro@globalone.net

  2. Contents • Overview • Corporate Security • TESTA II Network Security • Backbone Security • Access Network Security • Global Dial Access Security • Additional Security Options • Security Management

  3. Overview • Corporate Security Policy • IP VPN using MPLS - No Internet traffic • Physical control and security on the backbone • Controlled access to the EuroGate • Logical segregation of customer traffic based on strong routing protocol (port configuration) • Central Management (NMC) of the VPN configuration - No third-party access or delegation of network management function

  4. Corporate Security • Key elements of the Corporate Security policy are: • comprehensive staff screening • Physical security for network nodes and Operations support systems, with access to limited staff on a need-to-know basis • Password and user ID for network nodes and support systems, including enabling auditing features • Documentation of specific security procedures and processes • Continued review of security procedures as an inherent element of network operations. • Security Architecture focused on: • Securing network infrastructure to avoid network service disruption • Preventing and detecting fraud and abuse of Global One network services • Implementing overlay services to enhance the implementation of specific security policies

  5. TESTA II Network Security • Backbone Security • Backbone node infrastructure • Access Network Security • Quality of Service • Service level guarantees (e.g. availability) • Classes of Service • Security Management • Corporate security • Security Management

  6. LocalDomain D LocalDomain C EuroGate EuroGate EuroDomain EuroGate EuroGate LocalDomain B LocalDomain A TESTA II Network Security Backbone Security Layer “Door-to-Door” Security “Door-to-Door” Security Backbone Security

  7. Backbone Security • Fiber - secure Transmission Medium: • Backbone Transmission security on fiber optic links (backhaul route diversity, secure cable routing, heavy armoring, ..) • Impervious to radio frequency and electromagnetic interference • Access Management and Control: • All network equipment locations protected with access alarms • Alarms monitored continuously by Regional Control centres (NMCs) • Network Monitoring: • Real-time status and remote software control of switching & transmission • Remote diagnostic tools for adding, deleting or modifying circuits or viewing port condition • Only registered operators, with appropriate administrator functions, have access to NMC tools and systems. • External Protection • Denial of service attack: only LD users can access the EuroDomain • Tracking and support can be provided

  8. Access Network Security • Local Loops: • Ordered by Global One and currently provided by local Telecom Operators • In some countries, alternative carriers can be used • Security is the currently accepted level of security on the local loop • Customer Premises Equipment: • Provided and managed by Global One under an onsite Rental and maintenance contract. • Only Global One has access to the router configuration.

  9. Global Dial Access Security TESTA II EuroDomain Access Server Home Gateway VPDN Tunnel Application Host TESTA II Dial-up User AAA Server

  10. Global Dial Access Security • Only registered users have access to the Dial Access service • User Authentication via AAA server (Radius) based on the Network Access Identifier • Additional SecurID client can be used for strong authentication • Limits access to pre-defined resources on the TESTA II backbone • Performs user accounting for purposes of security and charge back

  11. Additional Security Options • Firewalling • Managed firewall service at site location • Optional network-based firewall • Dedicated secure IP VPN boxes performing: • Authentication (Remote keys) • Encryption (ITSEC) • Firewalling functions • Access Filtering • Restricted VPN configurations on the TESTA II backbone

  12. Security Management • Corporate Security Department responsible for: • Performing threat analysis • Conducting surveillance and detection services • Recommending overall solutions to security issues • Protecting management systems and applications
