Integrating public key cryptography into the simple network management protocol (SNMP) framework

There have been several attempts in the past to secure the Simple Network Management Protocol (SNMP). Version 3 of the SNMP protocol introduced a User-based Security Model (USM) which comes with its own user and key-management infrastructure. However, many operators are reluctant to introduce a new user and key management infrastructure just to secure SNMP. This paper describes how the Secure Shell (SSH) protocol can be used to secure SNMP and it provides a performance analysis of a prototype implementation which compares the performance of SNMP over SSH with other secure and insecure versions of SNMP.

In order to improve the efficiency and stability of Space-Terrestrial integrated network resource management and control, a multi-element multi-domain network management protocol (MMMP) is proposed. Based on MMMP, Space-Terrestrial integrated network management and control system (STi-NMCS) is designed. By abstracting network management objects, the efficiency of network management is greatly improved. Experiments are carried by comparing the overhead and the success rate of network management between MMMP, simple network management protocol(SNMP) and common management information protocol (CMIP). The results show that by using MMMP rather than SNMP as well as CMIP, the Space-Terrestrial integrated network management system archives high success rate and low management overhead.

In this paper, we present the network management model for a multimedia service in the broadband wireless access network (BWA), also known as the local multipoint distribution service. The BWA typically provides band ranges between 10-66 GHz, and is further characterized by high rates and short ranges due to rain and foliage attenuation. The proposed model consists of a base station manager (BS) a SNMP (simple network management protocol) agent, and a user-friendly graphic user interface (GUI). The manager-to-SNMP agent communicates using a mechanism based on the extensible SNMP trap feature. SNMP agents, which are used to manage elements of the BWA network, communicate with the BS manager using SNMP PDU. BS manager provides configuration management function and fault management function.

This paper proposes a system architecture design for the Internet of Things (IoT) implemented in temperature and relative humidity measurement using DHT 11 temperature and humidity sensor. Simple Network Management Protocol (SNMP) is used to manage different network devices and transfer information so that the ESP32 Wi-Fi microcontroller connected to the sensor can communicate with Open Platform Communication (OPC) server. In addition, the network variables are identified by Object Identifiers (OIDs) then collected to Management Information Base (MIB). These two elements are required by the SNMP monitoring tool for enabling the user to monitor network infrastructure and run troubleshooting. Data acquired from the ESP32 Wi-Fi microcontroller are accumulated on the OPC server using SNMP and subsequently transferred to the OPC Client such as Human Machine Interface (HMI) and OPC data logger. The OPC server has a ping channel feature to determine network latency measured as a round trip time – the time taken for data to get its destination and back again. Later on, the ESP32 microcontroller was also connected to a mobile application via Wi-Fi for displaying real-time data simultaneously with the HMI. The SNMP network latency test on the proposed system architecture design results in 126,33 ms for 13 minutes without a corrupt packet of data. The result indicates SNMP can be used as an alternative protocol for IoT data communication.

Energy automation systems have been expanding and there are more Ethernet capable devices in the network. Protection relays, switches, GPS and also computers have many critic diagnosis information available via the network interface. The intention of this paper is to present how the already available information can be used in the human-machine interfaces and SCADA systems to have a more detailed diagnosis of the network and its devices. Information like IED (Intelligent Electronic Devices) health status, CPU loads, fiber-optics light intensity, GOOSE (Generic Oriented Object Substation Event) message errors, can be used to early detect equipment failure and network instabilities. Early analysis can prevent problems with the equipment interlocking and protection functionalities and improves the power system availability. The simple network management protocol (SNMP) is a management protocol widely implemented, which makes it an ideal manufacturer-independent solution for this purpose. To test this concept a Siemens SCADA system was used as a manager of the SNMP enabled devices in an already commissioned power plant with Siemens Siprotec 4 protection relays. Further ideas were also developed.

– Installation of the honepot sensor on Raspberry Pi device integrated with Modern Honey Network(MHN) is a DSSDI UGM action to see the threats of existing public Network, so it can be preventive action. But theinstalled Honeypot sensors sometimes have problems in the form of overload on the System so that data attacks arenot recorded. It is necessary to develop a monitoring System on the Honeypot System to monitor and manage Systemresources and to analyze Honeypot data needs. System monitoring which is one of the Network Management System(NMS) functions can be implemented with Simple Network Management Protocol (SNMP) to monitor theperformance of Honeypot sensor devices. From monitoring the Honeypot System shows the Honeypot sensor deviceoverloaded in memory. In addition, from the monitoring is seen the influence of the number of attacks on Systemperformance.

The evolution of internet results in the emergence of online communities. Numerous communities exist today with millions of users. Security, privacy and availability are the top constraints to be focussed in online communities. Among the other security violations, denial of service (DoS) ranks first as it disrupts the availability of services. DoS attack is reported in a popular virtual world, Second Life which made the complete portal inaccessible to legitimate users. As TCP-SYN is the more prevalent attack strategy of DoS, our solution is aimed to provide efficient detection of DoS in the Second Life community. Detection and differentiation of attack traffic from the legitimate is achieved through simple network management protocol (SNMP) and machine learning algorithms. In spite of the 'n' number of solutions, an efficient outperforming strategy with accurate attack detection is the critical requirement. This paper focuses on the DoS attack detection, classification using SNMP MIB variables and linear regression model. Experimental observation proves the detection accuracy of the method under DoS.

The growth in the development of distributed manufacturing systems necessitates increases in efficient technologies in order to facilitate management of the networked resources. Systems such as manufacturing automation protocol (MAP) already exist which were specifically designed for managing networked manufacturing devices. However, MAP has been criticised for being over-complex and expensive for small–medium sized enterprises. The simple network management protocol (SNMP) was designed for managing TCP/IP networks, and we argue that it can also be used for managing networked manufacturing devices. However, SNMP, like MAP, is based upon a client/server architecture, and both have scalability issues. We also investigate the use of mobile agent (MA) technology as a means of managing a domain of manufacturing devices. An integrated network management framework based on MA technology is developed to direct the research into the investigation of aligning network management paradigm to the strategic management decision.

The fault detection of satellite network is required to collect data of managed objects via network management protocol. Therefore, it is a premise of fault management of satellite network to choose a network management protocol designed according to the feature of satellite network. Due to the uniqueness of satellite network, the current network management protocol and standard, such as simple network management protocol (SNMP) and CMIP, are both directly unsuitable for the applying of fault detection of satellite network. By analysis of multiplex network management protocol (MNMP), this paper focuses on the discussion of the MNMP application in the fault detection of satellite network. Besides, in order to investigate the performance of fault detection based on MNMP, this paper also gives a performance test on several means of data acquisition of MNMP, and compares as well as analyze it with SNMP.

The authors expand on their experience in a practical network management system by using the simple network management protocol (SNMP) in the context of a large-scale open systems interconnection (OSI)-based campus-network. Various aspects of network management are examined and the importance of time is shown. The network management infrastructure comprises intelligent, time-synchronized agents and expert managers. Agents are deployed to collect information about the network segments to which they are attached. The expert manager talks to the agents and gathers relevant network information which is used in conjunction with a network knowledge base, to reconstruct the overall network traffic characteristic, to evaluate the status of the network and to take/suggest some action. The model allows some global control, monitoring and management without installing agents on all elements connected to the network. The use of time labels and narrow time windows enables the manager to obtain a reasonably accurate picture of the network status. The introduction of composite time-labeled objects reduces the burden of management traffic on the network. >

Cloud computing is a dynamic environment in terms of both topology and network technology. The resources in the cloud environment are scalable and it is offered to the customer's on-demand which leads to a drastic increase in the customer's count. The key design feature of the internet and the protocols used to access the cloud services makes it vulnerable to various security issues. Out of the critical security issues, denial of service (DoS) ranks first since it disrupts the availability of cloud services. This paper aims to provide a detection mechanism for DoS attack in the cloud computing environment using the simple network management protocol (SNMP). SNMP is efficient in detecting the TCP-SYN flood attack in the cloud environment. Impact of the attack is estimated in terms of the system parameters CPU utilisation, I/O and latency.

In this paper, a new approach and solution of the one of the biggest problem on mission critical networks, network and bandwidth optimization will be described. The developed “Network Quality and Resource Manager” ensures the quality of network bandwidth and transfer rate on isolated mission critical networks like high resolution IP based security camera surveillance systems. The “Network Quality and Resource Manager” uses “Quality of Service”, and “Address Resolution Protocol Table” via Simple Network Management Protocol (a.k.a. SNMP) over manage-able at-least 2nd layer network devices. Hence NQRM uses SNMP, it is vendor independent and can work with any network architecture.

Modern communication networks cannot get along without quality of service (QoS) assurance. QoS-support mechanisms offer preferential treatment for specific traffic classes that is required especially by real-time network applications. Unfortunately current QoS technologies have certain disadvantages and limitations and therefore they are not always able to guarantee the required QoS level. This paper introduces a quality of service support system that improves the most often used quality of service support technology called Differentiated Services (DiffServ). The system proposed utilizes the Simple Network Management Protocol (SNMP) for the acquisition of configuration information from the edge router of the DiffServ domain. This information is subsequently used to control the allocation of network resources within the QoS assurance process. In order to evaluate this system we used the OPNET Modeler simulation environment where we built a simulation scenario able to interact with real network components. For this purpose we implemented the SNMP protocol into the OPNET Modeler and used it for acquisition of management information, stored in the Management Information Base (MIB) of the network node. The paper describes in details the improved QoS-support mechanism and the simulation model able to cosimulate the behavior of both real and virtual network elements.

Along with the widespread development of Internet and mobile applications, the demand for more flexible and dynamic networking services increases. It becomes a new challenge for many carriers to deploy a variety of new services by effective provisioning of network resources. Software-Defined Networking (SDN) is a novel approach to make networks reconfigurable and extensible such that new services can be deployed with existing network devices. By decoupling the controller plane from the data plane in network devices, SDN brings networks programmability of the data plane and centralization of the controller plane. Conventional Operations Support Systems (OSSs) were developed to manage networks in a standard fashion with Simple Network Management Protocol (SNMP) or proprietary protocols. SDN provides a new framework in managing SDN-enabled devices. A new issue for carriers is how SDN-enabled networks and devices can be monitored and controlled by current OSSs. This paper focuses on performance management and aims to develop an efficient scheme to collect traffic statistics data via the SDN controller plane. Similar to Bulkstat, an SNMP-based mechanism for periodic collection and transfer of MIB objects, the proposed scheme for bulk traffic statistics collection is developed in the controller plane and provides a northbound interface for upper network management applications. Instead of using SNMP and MIBs, the scheme is implemented by periodically gathering statistics information of flow tables from SDN-enabled switches via the OpenFlow protocol.

Presents an open, digital interface-OpenIF/sup TM/-designed by RadioScape Ltd., which enables high speed control and user data to be sent between front-end, RF processing units, and back-end, generic signal processing components, for use within base station, test and prototyping products. The adoption of such an interface is central to the success of software defined radio (SDR), both as a design-time and run-time technology, as it enables the production of analogue/RF components independently from the digital domain hardware and software. OpenIF/sup TM/ utilises the user datagram protocol over IP (UDP/IP) to carry information. The configuration of RF hardware is realised using the simple network management protocol (SNMP), as many different technical specifications can be represented as a standard set of messages coupled with a small set of application specific messages built from the standard set. Because the interface is open and extensible, the overall system architecture need not be changed when processing different communications or broadcast standards. The interface is decoupled from any underlying physical layer (although a particular variant, LVDS, is described here). RadioScape has used the OpenIF/sup TM/ interface in its generic baseband processor (GBP) platform, a FPGA/DSP substrate for high-bandwidth digital processing. Having found the interface extremely useful internally, we present it here for consideration by the rest of the industry. This paper aims to give the reader a broad overview of the OpenIF/sup TM/ interface and is not a standardisation document or proposal.
