Netflow Accumulates and Monitors Network Traffic Essay

Networking is part of our everyday lives now. Weather is us using our phones, computer, using GPS for directions, watching 3D movies and TV’s or in our work environments. Network Security has become search a big issue since our day to day live started to be more involve with us. These problems involve in all type of shapes and forms where some of these issues are cyber attacks, physical attacks, or abuse of policies. People are really exposed due to the amount of internet activities we have going on in most of our networks. There are two fundamentally different when it comes to networking, the data networks and the synchronous network comprised of switches. With that being said there are also

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

Monitored the network congestion in order to achieve the optimal performance out of a network infrastructure.

In this paper, we present the first data collection and profiling process result in our research framework. At this time, the second and the third data collection process are still on going. If it is completed, we will conduct the second part of our proposed experiment. The challenges is, we have to obtain an appropriate and enough RAW data that need more prolonged time for trial and error. We have to design scalable devices and computation architecture, since the system proposed will handle high volume of traffic at national level network. A comment and suggestion are welcome.

Wire Shark will be used to allow deep packet level analysis of the network and to mitigate possible network latency problems. Ping is also used to provide the user the ability to check the network conductivity from the workstation to a specific node or internet site. Trace Route is still another utility that can show the full connection path between the user’s workstation and the desired destination system being reached. The use of these tools can decrease the amount of time of an outage on a network by identifying which devices are not passing on the packets and where the packets drops are taking

The National Institute of Standards and Technology (NIST) defines Information Security Continuous Monitoring as “maintaining ongoing awareness of information security, vulnerabilities, and threats to support organizational risk management decisions” (Dempsey, et al., 2011). NIST advocates for continuous monitoring of information security systems, by the process of defining the program, establishing it, implementing the program, analyzing and reporting findings, responding to the findings, and reviewing and updating the program. Additionally, they believe that in order to be more cost effective, and to improve efficiency and reliability of the monitoring program, automation would be the way to go. By making use of the latest trends in technology such as machine learning and data mining, algorithms can be developed to detect patterns, which would ordinarily be missed by the human eye. This is especially true of voluminous data where it is time consuming and just plain difficult for personnel to sift through. Such implementations leaves the security professionals with time to tackle the issues which would require human involvement (Dempsey, et al., 2011). One example of an automated monitoring system is a firewall. The job of a firewall is to monitor and regulate the network traffic coming into and out of a system, which could be as small as a single home computer connected to the internet, to several thousands of devices in an organization the size of Amazon or

Network improvement has become follower in today’s modern life. The more we work the more we are affected to network and thus normally having always new requirements. To implement more efficient methods is needed first to predicate them. This predication needs to be developed before the requirements are very high. Users always expect more from networking while they compare old and current methods they’re working on. If network improvement performs poorly it would damage many businesses, consumer satisfaction etc, thus forthcoming of network should always be improved and not go down. One of the greatest improvements made on network field was

Duke Energy should carefully plan and address the security aspects of its network by implementing appropriate firewalls. Duke Energy should implement appropriate security management practices and controls when maintaining and operating a secure network. It is imperative to ensure that the architecture of its network complies with industry standard security requirements. Duke Energy 's IT organizations should commit to the ongoing process of maintaining the security of device connected to their network.

In addition to controlling access, Network Sentry detects and identifies devices that are already on the network. “We discovered more than 1,000 unregistered, rogue

The purpose of this document is to improve learning from the Cap-Net programme, ensure adequate monitoring of the project and assist our partner networks monitor their own activities. This monitoring, evaluation and learning plan (MELP) has been developed as a guide to monitoring and evaluation within the Cap-Net project and the tools listed are applied by the project management team and network partners. The tools will be adjusted to meet the needs of partner networks and used as a basis for addressing monitoring needs at network level. It is expected that the tools and strategy presented in this

Software defined networking is a new concept that redefined the current network device architecture and the way they behave. Due to the exponential growth of the Internet and services attached to this worldwide infrastructure, a number of issues have cropped up in modern day networks. This paper discusses a few of these limitations and how the software defined networking approach tries to alleviate them. OpenFlow, released in the year 2008, is a commercially viable implementation of this concept that is being well received by the networking industry at large. The paper also discusses the OpenFlow protocol, its implementation and the challenges facing its widespread acceptance

The logs from network infrastructure devices must be proactively monitored and analysed for any possible threats or attacks and must be addressed immediately for the threat mitigation and

Remote monitoring is a method used to interchange network monitoring data between Network Monitors and console systems. RMON offers network administrators with more liberty in selecting network-monitoring probes and consoles with features that meet their precise networking requirements. RMON is an Internet Engineering Task Force (IETF) standard monitoring requirement document that allows numerous network agents and console systems to exchange network monitoring data. A typical specification of RMON would be that in which Simple Network Management Protocol (SNMP) agent in a switch be to monitor all the traffic flowing among switches on connected LAN nodes / segments.

The very first step in auditing networks is to define where to analyze the traffic. Taking a common scenario for analysis, the following assumptions were made. There is a switched network made up of a number of switches, several terminals and a file server. Network performance has dropped, however the cause is unknown. There is no IDS (Intrusion Detection System) that can alarm or inform about attacks or network malfunction. Also, it is known that there are no problems with the transfer rate of the file server to LAN (Local Area Network) terminals [3]. Furthermore, network equipment does not have Netflow protocols to analyze traffic remotely. Wireshark was chosen to analyze the above scenario. The first doubt which arises is where to install Wireshark. It would seem logical to install Wireshark on the file server itself to analyze the traffic that flows through this network segment. However, there could be situations in which there is no access to the server physically or quite simply for security reasons. Thus, Wireshark cannot be installed there. Some alternatives are provided in the following paragraphs that enable to capture traffic without having to install Wireshark on the server.

A significant amount of research efforts have been directed towards attempts at providing high quality service for real time applications of IP based networks in the past decade. The core idea of these techniques is to control the IP network congestion level which is the main cause of delays/losses, and also imposes upper bounds on these events. Traffic policing is one of the techniques used for this purpose. These techniques makes the assumption that users generating flows/calls will specify the setup time by using Service Level Agreement (SLAs) i.e. the characteristics of the traffic that they emit to the network. Therefore, these techniques are employed to ensure that the generated traffic is within the conforms of previously agreed contracts. One of the most popular traditional traffic policing techniques is the Leaky Bucket (LB). Average rate and the maximum burst size/length of a
