Several CAs (Certificate Authorities) have formed an advocacy group called the CASC (Certificate Authority Security Council), which will focus on promoting new security standards, policies and best practices for SSL (Secure Sockets Layer) deployment on the Web. CASC was launched on Thursday and its member list includes representatives from Symantec, Trend Micro, Comodo, DigiCert, Entrust, GlobalSign, and Go Daddy. CAs are organizations that issue digital certificates.
