Sun has announced a series of updates to its flagship Solaris operating system. Solaris 10 11/06 OS enhances efficiency, safety, and reliability. New security features include Solaris Trusted Extensions, which protects sensitive data and applications using labeled security technology. Secure By Default Networking automatically configures a system to be impervious to network attacks by disabling many unused services, thus reducing the network exposure, while leaving the system fully functional for typical use. In the meantime, HP will be supporting Solaris on its systems.
