CAN/CSA-ISO/IEC ISP 10608-8-01
ISO/IEC ISP 10608 is applicable to End Systems concerned with operating in the Open Systems Interconnection (OSI) environment. It specifies a combination of OSI standards which collectively
provide the connection-mode Transport Service using the connection-mode Network Service.
ISO/IEC ISP 10608-5 specifies subnetwork type dependent requirements for end system operation when the end system is attached to an X.25 packet switched data network by a dedicated (permanent) access line and using virtual calls.
This part of ISO/IEC 10608 specifies the profile requirements for th e provision of security services using cryptographic techniques with Network Layer Security Protocol connection-mode and SDT-PDU based protection for use with X.25 packet switched data networks as specified in ISO/IEC 10608-5.
1.2 Position within the Taxonomy
The taxonomy of profiles is specified in ISO/IEC TR 10000-2. This part of ISO/IEC ISP 10608 supports security services for TA1111 and TA1121 profiles as specified in ISO/IEC ISP 10608-5.
Note: ISO/IEC TR 10000 currently does not identify security sub- profiles. Profiles based on this part of ISO/IEC ISP 10608 may be referred to as TA11n1S2, or TA11n1S2C if confidentiality
1.4 Security Services
The following security services are within the scope of this part of ISO/IEC ISP 10608:
a) Peer entity authentication
b) Connection integrity without recovery (including replay protection)
c) Access control using security labels
Note: Where label based access control is not enforced by a system a null label may be employed.
d) Connection confidentiality (optional)
e) Traffic flow confidentiality (optional)
1.5 Security Mechanisms
This part of ISO/IEC ISP 10608 provides no assurance as to the strength of the security mechanisms employed.
This part of ISO/IEC ISP 10608 does not specify the cryptographic algorithms to be employed.
