ccna 8-10.Modern enterprise networks typically use wireless controllers, APs, and wireless management systems to provide comprehensive protection against wireless attacks. Wireless environments are protected through integrated infrastructure threat protection, advanced RF environment visibility, and wireless security cooperation. For fully integrated wireless, an integrated infrastructure approach reduces costs while streamlining security operations. Suchsolution has the following benefits. Proactive threat and intrusion detection capabilities to detect and defend against wireless attacks. Comprehensive security for confidential data and communications. Single user identification and policies simplify user management and protection against unauthorized access. Cooperation with wired security systems ensures comprehensive wireless security features and protection.6.4.1.3 Introduction to VoIP SecurityIP telephony, IP Private Packet Switches (PBXs), voice gateways, voicemail systems, and essential protocols are also common in enterprise networks. These technologies and protocols enhance productivity and ultimately save organizations money in telephony communications. By using IPPBX, organizations can eliminate traditional PBXs and enjoy the benefits of IP telephony communication through converged networks. IPPBX provides call control capabilities when used with IP phones or softphone applications, providing a distributed, scalable approach to PBX functionality. The deployment models for Cisco IP telephony communications solutions fall into the following categories.Single-site deployments. Centralized call processing with remote branches. Distributed call-processing deployments.Cluster over IP WAN. The choice of deployment model depends on the needs of the organization, such as the size of the network, characteristics, and WAN bandwidth availability.6.4.L4 Introduction to SAN SecurityEnterprise networks also use storage area networks. Storage networks are at the heart of contemporary data center architectures, providing a network platform that can help IT departments achieve lower total cost of ownership, increased resiliency, and greater flexibility. Storage networking solutions offer several functions6.4 Wireless, VoIP, and SAN Security 171capabilities.
