Planning for security

Whether you are implementing Z and I Emulator for Web purely within your corporate network, or you are using it to provide access to your host systems over the Internet, security is a concern. This chapter provides an overview of Z and I Emulator for Web security.

• Transport Layer Security (TLS). Provides encryption, certificate-based authentication, and security negotiations over an established Telnet or FTP connection. See TLS for Z and I Emulator for Web for details.
• The Redirector. Supports TLS between Z and I Emulator for Web clients and the Z and I Emulator for Web server. See The Redirector for details.
• Firewalls. You can configure Z and I Emulator for Web to go through a firewall. See Using Z and I Emulator for Web with a firewall for details.
• User ID security. Includes Web Express Logon, Native Authentication, and Windows Domain logon. See User ID security for details.
• Federal Information Processing Standards (FIPS) environments. See FIPS environments if your environment requires that your security components use FIPS-certified components/modules.
