SDNA Model. In lieu of the above challenges, which only represent a partial picture of the vast problems of network security, companies such as Cisco have come to realize that each and every device pertaining to a network should have its part to play in the security of the network. The devices should interact in a cooperative manner in order to mitigate the attacks. This is the core idea behind the Cisco self-defending network architecture.
The self-defending network strategy is based upon three main principles which are discussed as follows. Systems in SDNA. In total there are four systems which can be said to be a part of this architecture. The term system refers to the combination of hardware and software required to implement the previously mentioned principles of self-defending architecture.

Here is a simple definition of a network perimeter: Network perimeters are established by Routers. Some of the most important and intriguing challenges faced by modern networks are as follows: Sophisticated attacks — gone are the days when attackers were novices or hardly had any tools at their disposal.
Nowadays attackers use increasingly malicious and deadly tools to carry out attacks and the propagation times are on the decline. Time available for defending against new attacks is increasing becoming shorter and shorter. Even though the use of most sophisticated tools for security is on the rise, a slight loophole here or there would do away with all the arrangements.
It is becoming increasingly difficult to identify threats and attacks amongst complicated networks which possibly contain multiple devices from various vendors, using various platforms and so forth. SDNA Model In lieu of the above challenges, which only represent a partial picture of the vast problems of network security, companies such as Cisco have come to realize that each and every device pertaining to a network should have its part to play in the security of the network.
Integration — this principle ensures that all network devices have their share in policy enforcement as well as implementing the defense strategy. Collaboration — this principle ensures that all the devices and services work in collaboration and harmony to achieve the final goal which is the prevention of attacks Adaptation — this refers to the proactive security approach adopted for automatic prevention of threats Systems in SDNA In total there are four systems which can be said to be a part of this architecture.
A technical control is deployed to ensure that all the communications of data and voice are confidential and this is referred to as secure communications component. SDN shows that the approach to security has evolved from a point product approach to this integrated security approach These self-defending networks will identify threats, react appropriately to the severity level, isolate infected servers and desktops, and reconfigure the network resources in response to an attack.
The vision of the Self-Defending Network brings together Secure Connectivity, Threat Defense and Trust and Identity Management System with the capability of infection containment and rouge device isolation in a single solution.
