Preferred Architecture for Cisco Collaboration Release 15 On-Premises Deployments PAGE 41
Security

Security A collaboration deployment is subject to threats such as denial of service, unauthorized access, toll fraud, and eavesdropping so it is critical to ensure that it is secured against these threats. You should take a layered approach by securing various network levels: secure physical access, network infrastructure, collaboration applications, and collaboration endpoints (Figure 19). Solely following the recommendations in this section does not guarantee a secure environment, nor will it prevent all penetration attacks on a network. You can achieve reasonable security by establishing a good security policy, following that security policy, staying up to date on the latest developments in the hacker and security communities, and maintaining and monitoring all systems with sensible system administration practices.
