MOUNTAIN VIEW — IBM Corp. and network security provider VeriSign Inc. have formed a broad technology and marketing partnership aimed at improving authentication and access-control services for businesses. 

Financial terms of the deal, which is to be formally announced Tuesday, were not disclosed. 

In addition to developing new security services together, Armonk, N.Y.-based IBM and Mountain View-based VeriSign said they would help market each other’s existing offerings. 

IBM already supplies VeriSign with some servers and other hardware, and the deal calls for more such purchases. But VeriSign also will continue to equip itself with gear from Sun Microsystems Inc., executives said
