  • Trend Micro has taken the multilayered security approach to the next level of sophistication with its Trend Micro Threat Management Services network security "overwatch" service. Threat Management Services provides an additional security layer that greatly strengthens an organization's security infrastructure by monitoring the network for active infections that have successfully infiltrated. Once the threat discovery occurs, in real time, the network overwatch layer intercepts the attack and performs automated containment and remediation.

  • The OSI Reference Model is useful because it gives some commonly used terminology, though it might mislead you into thinking that there is only one way to construct a network. The reference model was designed by an organization known as the International Standards Organiza- tion (ISO). The ISO decided it would be a good idea to standardize computer networking. Since that was too big a task for a single committee, they decided to subdivide the problem among several committees. They somewhat arbitrarily chose seven, each responsible for one layer.

  • This chapter deals with Cisco IOS Network Foundation Protection (NFP) as a framework for infrastructure protection, all its components, and commonly used countermeasures asfound in Cisco IOS devices. More precisely, this chapter differentiates the security measures to be implemented on the three conceptual planes of Cisco IOS devices: the control plane, the data plane, and the management plane. This chapter also discusses using Cisco Configuration Professional (CCP) to implement security controls on Cisco IOS routers.
