correct TPM chip. Procedures are provided for encrypted volume backup and
configuration of ServiceGuard clustering when TCS keys are employed.
HP-UX SecureShell now contains support for utilization of TCS keys for servers
establishing encrypted sessions with remote clients. This prevents a SecureShell
server from being easily transferred to another platform.
With HP-UX OpenSSL, TCS key protection can be easily integrated into applications
that rely on OpenSSL for cryptographic operations. The Stunnel product available
with Internet Express provides a solid example of how TCS keys can be integrated
through OpenSSL. An application server employing Stunnel to establish encrypted
sessions can utilize TCS keys through Stunnel.

B.2.7 HP-UX Whitelisting
HP-UX Whitelisting (WLI) protects the system from unexpected downtime and
denial-of-service by preventing inadvertent or illegitimate changes to the critical system
files. It also protects files from unauthorized access by granting permissions only to the
authorized applications, irrespective of the user (uid) executing the application. WLI is
a cryptographic key-based product. Whitelisting security features are based on RSA key
ownership and encryption technology. The authorization is provided by policies along
with the traditional Discretionary Access Control(DAC). WLI security features are imposed
through RSA signatures and enforced through signature verification. Therefore, regular
files and directories may be protected from access by any user including super user.

B.3 Protecting Identity
In addition to the security products that are discussed in Part III Protecting Identity, the
following security products offer additional identity protection.
B.3.1 HP-UX AAA Server (RADIUS)
The HP-UX AAA Server utilizes the industry standard Remote Authentication Dial-In User
Service (RADIUS) protocol and Extensible Authentication Protocol (EAP) to provide
standards-based user authentication, authorization, and accounting services to network
devices and software applications.
The HP-UX AAA Server can be utilized for securing wired and wireless LAN access,
provide authentication and accounting for Virtual Private Network (VPN) gateways,
firewalls and other network devices, and to enhance the security of RADIUS-enabled
software applications in Enterprise and Service Provider environments.
