SISTEM MONITORING JARINGAN REALTIME BERBASIS INTERNET CONTROL MESSAGE PROTOCOL

Network monitoring in the company is more extensive and complex, each device must be connected to the network so that there are no obstacles when there is receiving and sending data from various devices. Problems on computer networks cannot be predicted when they occur and continuous monitoring is needed to ensure the network is connected properly and it is difficult to troubleshoot network damage. Therefore, a network monitoring system is needed to check the network so that administrators can find out network conditions. By using the Internet Control Message Protocol  to check the network continuously so that it can find out the condition of the device, taking into account the latency and data obtained by Packet Internet Gopher. Network checks and notifications use a backdoor working system or through a background process, control the process is also a network check log to find out which devices are often disconnected and to make network troubleshooting easier. In this paper, will be building a network monitoring system that displays network status and monitors the network continuously with telegram notifications, network logs to facilitate troubleshooting, Internet Protocol management and backdoor system settings by the name of SIMONIT

INTENT-AWARE FLOW REDIRECT USING SINGLE-HOP INTERNET CONTROL MESSAGE PROTOCOL (ICMP) EXTENSION

Techniques presented herein provide for a Control Agent that monitors flow distribution and Smart Network Interface Card (sNIC) capability and utilizes a simple Internet Control Message Protocol (ICMP) extension to instruct upstream node(s) to redirect traffic over other sNIC connected link(s). The techniques may be utilized for both Layer 2 (L2) and Layer 3 (L3) links and may provide a novel mechanism to leverage an sNIC for flow-based/intent-based/capability-aware load balancing and/or policy-balancing

Flow-Representation Approach For ICMPV6-Based Ddos Attacks Detection

In addition to the address expandability, IPv6 broughts new functionalities, such as Neighbor Discovery Protocol (NDP) and address auto-configuration scheme, which depends on Internet Control Message Protocol version 6 (ICMPv6) protocol. ICMPv6 is delegated with more responsibilities than Internet Control Message Protocol version 4 (ICMPv4) in IPv4, and it is considered the backbone and the mandatory part in IPv6 native networks. IPv6 is vulnerable to a number of attacks from IPv4, besides new attacks have appeared within its new features. The most popular IPv6 attacks are Denial of Service (DoS) and its distributed version (DDoS) that use ICMPv6 messages. ICMPv6-based DoS & DDoS attacks are one of the major problems of today’s Internet, impacting economic damages in some serious cases

A Step on Developing Network Monitoring Tools

Network Monitoring involves Using Software or hardware based Systems or a combination of both to constantly observe the status of network devices and hosts, and notifies the network administrator via email, SMS or other alarms in case of error or fail. Observing the status of network device and hosts is done when the Monitoring System speaks with the networking devices or hosts using different protocols within the protocols stack (OSI Layer) ,see Figure1.The aim of this paper is to provide a footstep on developing a network monitoring tool for monitoring network devices and hosts. This is a software based Network Monitoring tool using a combination of Simple network Monitoring Protocol (SNMP), Internet Control Message Protocol (ICMP) and Port scanning concept. Key words: SNMP Manager, MIB, SNMP Agent, ICMP, Port Scanning, DNS, DHCP, SMTP, HTTP, Service;

ICMP: an Attack Vector against IPsec Gateways

In this work we show that the Internet Control Message Protocol (ICMP) can be used as an attack vector against IPsec gateways. The main contribution of this work is to demonstrate that an attacker having eavesdropping and traffic injection capabilities in the black untrusted network (he only sees ciphered packets), can force a gateway to reduce the Path MTU of an IPsec tunnel to a minimum, which in turn creates serious issues for devices on the trusted network behind this gateway: depending on the Path MTU discovery algorithm, it either prevents any new TCP connection (Denial of Service), or it creates major performance penalties (more than 6 seconds of delay in TCP connection establishment and ridiculously small TCP segment sizes). After detailing the attack and the behavior of the various nodes, we discuss some counter measures, with the goal to find a balance between ICMP benefits and the associated risks
