The Concept Of Software Defined Networking

amid this configuration we tend to look for guidance from them as data, control, and application planes. At base, the data plane is included system segments, whose SDN Data ways uncover their abilities through the Control-Data-Plane Interface (CDPI) Agent. On top, SDN Applications exist inside of the application plane, and impart their needs by means of northward Interface (NBI) Drivers. inside of the centre, the SDN Controller interprets these needs and applies low-level administration over the SDN Data ways, while giving pertinent data up to the SDN

Network Edge Security is the second-generation firewall architecture which changes 1st generation firewall paradigms. Network Edge Security pushes network security policy enforcement to the edge of the network (in other words all the way to the host) to address the insider problem. The architecture is not host-based software such as personal firewall but it is a host operating system independent and hardware based implementation on NIC (network interface card), with its own processor and memory that cannot be accessed by the host [5]. Network Edge Security

For this OPNET simulation I proposed a network design for a small organization Job Agency that provides employment opportunities to clients based on their skill set and required job market demand. The purpose of this design is to reach the requirement of security, disaster recovery of main servers. My design introduced more redundancy by implementing a firewall for the building and further optimized the network through more application and user profile. Each of the servers was deployed service based on their application and requirements. Also I categorized the users in the entire organization as either Administrator or Employees to provide best services as per their need. Moreover, this project considers a security solution in OPNET modeler by using Firewalls as a Network access control. It consists in practical network that will explain how the Firewalls can control the ingoing and the

Brocade is fully invested in making SDN completely modular to deliver New IP networks based on an open ecosystem. The Brocade SDN Controller is continuously built from the OpenDaylight code, with a virtuous cycle of contributions back to the OpenDaylight community. Physical and virtual networks from multiple vendors can be managed within the Brocade SDN Controller, and organizations can gradually introduce ever-larger portions of their existing networks into the controller domain with single-source technical support for the entire

Today, security devices such as Firewall, IDS are used on the many organization's networks for preventing security attacks. But, these devices can only diagnose illegitimate traffic and prevent it. They cannot prevent attacks which are as a result of the network devices vulnerabilities in the switches, routers, and etc. A malicious user who is within the network can implement many attacks by using these vulnerabilities. This paper explains the kind of existing vulnerabilities in Cisco switches and methods of preventing these attacks from

Software defined networking is a concept born out of the need to control network devices centrally, wherein the service offered by a device is decoupled from the device in a way that

Different Sectors of the work force who are heavily reliant on the networks for their core operation like the Banking, telecom, media, healthcare etc. are finding SDN as a solution to reduce their CAPEX and OPEX. SDN enhances the integration, management, and analysis of big data.

The company is an investment holding company of a group of subsidiaries in Leisure and Property Investment. TGV or formerly known as Tanjong Golden Village is one of the public limited company of Tanjong. TGV cinemas Sdn Bhd was founded in year 1995 and its product is cinema, film distribution.

Along with the rapid development of internet, there is an increasing demand to connect to internal networks from remote sites. When employees work from home or go on business trips, they want to connect to the internal private networks of their companies over a secure connection. The demand of secure connection to internal network led to the technology of virtual private network

The choice of Network Operating Systems will affect the low-level network protocols used, the way that the servers are administered and the way that users interact with network services. The NOS shapes the entire look and feel of the network environment. The NOS marketplace is very mature. The choices available, while relatively few, offer sophisticated features, high reliability, and relatively easy setup and administration.

The OFFN-RM project design requires an event listener to accept REST commands, updates controller state, and then construct appropriate action with the OpenFlow protocol. One testbed scenario involves a login scraper that will logically sit on top of the controller, to act as a clearinghouse for security events and to ingest information from devices, security mechanisms, appliances, identity services, and Globus; the scenario alternative is a direct connection. Customization of the login scraper seeks (a) to identify patterns and thresholds to block security threats, and (b) to detect and steer huge data flows around performance limiting mechanisms, by monitoring Globus GridFTP event logs and mining data transfer flows for multiple socket connections, restart markers, and data channel information. Login scraper customization will involve three events: (1) for events with a high priority, the action will be blocked and event listener code modified for REST commands to block source addresses; (2) for Globus flow events, steering will be accomplished with registration of the five-tuple; (3) for regularly scheduled events, automatic clearing of blocked source addresses will occur after a set time period. Extant hardware in the form of components of a decommissioned cluster (12 PowerEdge R620 compute nodes: dual Sandy Bridge E5-2650 8-core 2.0 GHz, 32 GB RAM) will be deployed for login scraper storage and containment

Internet Protocol Security (IPSec) is a protocol suite to make Internet protocol more secure by authenticating and encrypting every IP packet of one communication session. Beside from the changes that we have done for the first task, we need to implement IPSec in the tunnel, so figure 1 would be able to run GRE over IPSec. IPSec involves many component technologies and encryption methods, also IPSEC uses to main protocols to create security frame work: Authentication header and Encapsulating security payload. Authentication header does not provide encryption, that’s mean only authenticates the sender of the data. If we use authentication header alone, it can provide week protection and also it can show some problems if the environment uses NAT. While encapsulating security payload provides the same security services as authentication header, except the only difference is ESP can encrypt the payload. IPSec technology is competently invisible in its operation because it is based in network level. Another thing is the end users are not even directly interacting and are not required to learn about IPSec encryption. [2] The advantage to monitor all traffic that going through the network is because IPSec is based in network level. Also IPsec is not application dependent, so we do not need to worry about application compatibility issues. Also there is some disadvantages, the role to encrypt and

Internetworking's face a great deal of challenges for instance with reliability, connectivity, network management and flexibility. Since the different internets work at different levels and likely according to different programs, the challenge is in supporting all so that they work together whilst allowing a high degree of security that would provide data protection and provide rapid and smooth transmission of information. Internetworks must be constantly flexible to meet the changing needs
