The network simulator (NS-2) structure is containing a file called "cbrgen". This file was used to generate the traffic rates by generating random connections between source nodes and destinations. The original "cbrgen" file generates only CBR and TCP traffics. It generates connections in random manner between 0 and 180s only. The purpose of this paper is to enhance and modify this file by rebuilding it to generate additional types of traffics such as exponential on/off and Pareto on/off, as well as adding the simulated application "Telnet" that can be implemented easily with NS-2. The generated connections was also developed by letting the time to be distributed randomly between 0 and the simulation time instead of the fixed time between 0 and 180s. All these modification were tested and implemented many timed. Such modifications will make this simulator more practical and close to the real MANETs applications.

A monitoring system is needed to monitor a network topology from attacks that might occur at that time. A realtime monitoring system is needed to find out the attack. Therefore, in this study, an attack scenario on a proxy router was carried out using a brute force technique. The brute force technique is an efficient method that tries every possible login password character that the network administrator might use. This brute force technique already exists in the application used, namely Brutus. Brutus is executed by focusing the attack on port 23 telnet on the proxy router. The system log listed as a login failure caused by a brute attack on the proxy router will be forwarded by a script that is running to a notification with a network administrator telegram bot. From the results of research that has been carried out on the monitoring system on the proxy running in real time to notify the login failure message via telegram.

Network based intrusions have become a serious threat to the users of the Internet. Intruders who wish to attack computers attached to the Internet frequently conceal their identity by staging their attacks through intermediate "stepping stones". This makes tracing the source of the attack substantially more difficult, particularly if the attack traffic is encrypted. In this paper, we address the problem of tracing encrypted connections through stepping stones. The incoming and outgoing connections through a stepping stone must be correlated to accomplish this. We propose a novel correlation scheme based on inter-packet timing characteristics of both encrypted and unencrypted connections. We show that (after some filtering) inter-packet delays (IPDs) of both encrypted and unencrypted, interactive connections are preserved across many router hops and stepping stones. The effectiveness of this method for correlation purposes also requires that timing characteristics be distinctive enough to identify connections. We have found that normal interactive connections such as telnet, SSH and rlogin are almost always distinctive enough to provide correct correlation across stepping stones. The number of packets needed to correctly correlate two connections is also an important metric, and is shown to be quite modest for this method.

For many users of networks like the ARPANET, an RJE protocol is probably as important in terms of utility as the TELNET (or Virtual Terminal) protocol. In fact, the facilities provided by a TELNET and an RJE protocol are probably of most interest to the majority of users of computer networks. For these users, the network provides a fast, cheap telephone surrogate to a variety of computers for RJE and terminal access. The collection (and layers) of protocols that are used to provide these services must be organized to efficiently support a wide variety of applications and user needs. They should not pose an undue software burden on the user. The "official" NETRJE protocol for the ARPANET is built on top of the Telnet and File Transfer Protocols (FTP). A user of NETRJE establishes a Telnet connection using the User NETRJE program on his local host to a Server NETRJE process at the host where he wishes to submit a job (see Figure 1). The user then sends to the Server process ...

A mobile ad hoc network (MANETs) is a self-organizing network that consists of mobile nodes that are connected through wireless media. A number of unique features, such as lack of infrastructural or central administrative supports, dynamic network topologies, open communication channels, and limited device capabilities and bandwidths, have made secure, reliable and efficient routing operations in MANET a challenging task. The ultimate goal of the security solutions for MANET is to provide security services, such as authentication, confidentiality, integrity, anonymity, and availability to mobile users. To achieve the goals, the security solution need for entire protocol stack.. The proposed protocol ANODR-ECC with Telnet provide application layer security and it ensures route anonymity and location privacy and is robust against eavesdropping attack.For route anonymity, it prevents strong adversaries from tracing a packet flow back to its source or destination; for location privacy, it ensures that adversaries cannot discover the real identities of local transmitters. The simulation is done using network simulator qualnet 5.0 for different number of mobile nodes. The proposed model has exposed improved results in terms of Average throughput, Average end to end delay, Average packet delivery ratio and Average jitter.

The development of networks for converged services including voice, video and data over the same infrastructure requires appropriate planning and dimensioning. This work presents a methodology, based on discrete event simulation, that supports the dimensioning and planning of IP multi-service links with QoS requirements. One key aspect is the type of traffic considered: stream, which has strict time and bandwidth requirements (e.g., VoIP), and elastic, which tolerates a certain delay (e.g., FTP, TELNET and HTTP). Another key aspect is the validation of the simulation model. In the absence of actual data, an approximate and proven analytical model was used for comparison and validation. The validated simulation model can be incremented step by step in order to be used in more complex scenarios. Although we show the application of the method in a pre-defined case for the elastic traffic, the steps to be followed in a more general case are quite similar.

The dominant operating system on the Internet, Linux is quite prevalent, considering that the overwhelming majority of servers running web services, email services, and name services all depend on other open-source code that works with Linux. And this is where the trouble begins. So we need to secure Linux operating system. The Linux should be secured from three perspectives. Workstation Security, Network security, Server security since most of the network application such as DHCP, Telnet and Web servers are running on Linux it is necessary to secure these applications. All the threat, attacks are mostly are network based so the Linux network service must be so powerful to prevent these kind of attacks.

Increased performance, fairness, and security remain important goals for service providers. In this work, we design an integrated distributed monitoring, traffic conditioning, and flow control system for higher performance and security of network domains. Edge routers monitor (using tomography techniques) a network domain to detect quality of service (QoS) violations-possibly caused by underprovisioning-as well as bandwidth theft attacks. To bound the monitoring overhead, a router only verifies service level agreement (SLA) parameters such as delay, loss, and throughput when anomalies are detected. The marking component of the edge router uses TCP flow characteristics to protect "fragile" flows. Edge routers may also regulate unresponsive flows, and may propagate congestion information to upstream domains. Simulation results indicate that this design increases application-level throughput of data applications such as large FTP transfers; achieves low packet delays and response times for Telnet and WWW traffic; and detects bandwidth theft attacks and service violations.

Introduces the reader to the history of the Internet and the requirements for accessing it. The three major capabilities of the Internet-electronic mail, telnet, and file transfer protocolare discussed. Examples of how Jewish Internet resources may be used in the educational arena are included. The article concludes with a list of Jewish Internet sites. Definition and History of the Internet The Internet is an "inter"connected "net"work of networks. Like many scientific breakthroughs, it owes its existence to the military. In an attempt to assure speedy and reliable communications between the United States and its NATO allies, the Department of Defense established a telecommunications link between America and Europe in the 1960s. The following decade saw the creation of a universitybased network system, inaugurated between the City University and Yale, which was dubbed Bitnet ("Because It's Time Network"). In time many other networks sprang up, each sharing whatever information the administrator of a given system was willing to make available to outside users. The 1980s saw the arrival of a software protocol called TCP/IP, which could tie all of these networks together so that they could communicate, and so was born the Internet. The important point to take away from this history lesson is that even today, what is available on a given computer is whatever the administrator of the system chooses to make public. This

Intruders which log-in through a series of machines when conducting an attack are hard to trace because of the complex architecture of the Internet. The thumbprinting method provides an efficient way to tracing such intruders by determining whether two connections are part of the same connection chain. Since many connections are transient, and therefore short in length, choosing the best time interval to thumbprint over can be an issue. In this paper, we provide a way to shorten the time interval used for thumbprinting. We then study some special properties of the thumbprinting function. We also study another mechanism for tracing intruders in the Internet, based on a timestamping approach of passively monitoring flows between source and destination pairs. Given a potentially suspicious source, we identify the true destination of this source. We compute the error probability of our algorithm and show that its value decreases exponentially as the observation time increases. Our simulation results show that our approach performs well.

In Linux Router management, the Traffic Control tool is still the unique method provided to network managers for monitoring and configuration. Scripts invoked through telnet are used for this purpose. Router monitoring is obtained by parsing the report created from the tc show command. This leads in signifieant load for the management system imposing barriers for real time and dynamie management. The purpose of this paper lies in presenting a prototype implementation of the DiffServ MIB based on the Traffie Control API. The fundamental objective of this implementation is to provide an SNMP management framework for DiffServ Linux Routers. It is shown that, on the basis of the SNMP functionality, efficient and real-time management can be obtained, enabling the introduetion of relative differentiated services.

Reflection on the forms and possibilities of Internet use in education does not keep pace with the speed with which access for schools is provided worldwide. For an in-depth educational discussion, we need to differentiate types of Internet applications. We will present a model that was developed for the categorization and evaluation of (stand-alone) interactive media ([Baumgartner 1995] [Baumgartner and Payr 1994 and 1996]) and that we use now to contribute to a more detailed and specific educational discussion of Internet use. After a short review of the foundations on which the model is built we will illustrate its application to the Internet, using existing sites as examples. 1. Internet as medium, Internet as tool In order to submit the multitude of Internet services and applications (like e-

Start Network devices are generally programmed over the serial ports (COM-RS232) or over the network via telnet protocol or ssh protocol. The communication process via the Telnet protocol and COM port is done unencrypted. Therefore, there is a possibility to listen and change the communication by an intervening hacker. In order to prevent this, the hardware is designed described below. With this developed system, serial communication has been encrypted by adding RSA encryption using hardware between network devices which needs configuration with PC.

Gytech Indosantara Mandiri Ltd. in the last few years experienced many Cybercrime attacks on the Web Server which caused many moral and material losses. Therefore, it is necessary to consider ways to fight and prevent attacks on the webserver. One way to fight and prevent attacks is to use the Attack Signatures method by using ModSecurity and fail2ban as a Web Application Firewall (WAF). ModSecurity is used to detect and prevent the occurrence of Cyber Crime in the Http and https services. Whereas Fail2ban is used to prevent Bruteforce attacks on ssh, FTP and telnet services. Modesecurity, which acts as a Web Application Firewall (WAF) will send logs to Fail2ban when exploits occur on the Web Server. Meanwhile, Fail2ban will block the Attacker's IP address so that both can be used as a Web Application Firewall or can be used as layer 7 network security.

Individual machines are no longer sufficient to handle the offered load to many Internet sites. To use multiple machines for scalable performance, load balancing, fault transparency, and backward compatibility with URL naming must be addressed. A number of approaches have been developed to provide transparent access to multi-server Internet services including HTTP redirect, DNS aliasing, Magic Routers, and Active Networks. Recently however, portable Java code and lightly loaded client machines allow the migration of certain service functionality onto the client. In this paper, we argue that in many instances, a client-side approach to providing transparent access to Internet services provides increased flexibility and performance over the existing solutions. We describe the design and implementation of Smart Clients and show how our system can be used to provide transparent access to scalable and/or highly available network services, including prototypes for: telnet, FTP, and an Internet chat application.

We design and evaluate an adaptive traffic conditioner to improve application performance over the differentiated services assured forwarding behavior. The conditioner is adaptive because the marking algorithm changes based upon the current number of flows traversing through an edge router. If there are a small number of flows, the conditioner maintains and uses state information to intelligently protect critical TCP packets. On the other hand, if there are many flows going through the edge router, the conditioner only uses flow characteristics as indicated in the TCP packet headers to mark without requiring per flow state. Simulation results indicate that this adaptive conditioner improves throughput of data extensive applications like large FTP transfers, and achieves low packet delays and response times for Telnet and WWW traffic.

Instant messaging(IM) is a real-time communication medium between two or more people. Users can exchange messages privately or involve in group conversations. Today, IM does not only allow text messages, it can also send images and audio and video conversation. Although it is deemed as a social tool, it is not restricted for communication between people. Besides people, Software can be also involved in IM conversation, this kind of software is called IM bot. IM bot is being used to provide user with weather, stock exchange and local news. However, the use of IM bot type software in system administration field is not much studied and it is also not much available. The goal of this project is to develop an IM bot to provide system administrator with remote machine status and information. A daemon type software is developed to create the machine presence on the IM network and allows system administrator to interact with the machine as the same service provided by Telnet and SSH.

Hackers on the Internet usually send attacking packets using compromised hosts, called stepping-stones, in order to avoid being detected and caught. With stepping-stone attacks, an intruder remotely logins these stepping-stones using programs like SSH or telnet, uses a chain of Internet hosts as relay machines, and then sends the attacking packets. A great number of detection approaches have been developed for stepping-stone intrusion (SSI) in the literature. Many of these existing detection methods worked effectively only when session manipulation by intruders is not present. When the session is manipulated by attackers, there are few known effective detection methods for SSI. It is important to know whether a detection algorithm for SSI is resistant on session manipulation by attackers. For session manipulation with chaff perturbation, software tools such as Scapy can be used to inject meaningless packets into a data stream. However, to the best of our knowledge, there are no exis...

Attackers on the Internet often launch network intrusions through compromised hosts, called stepping-stones, in order to reduce the chance of being detected. In a stepping-stone attack, an intruder uses a chain of hosts on the Internet as relay machines and remotely log in these hosts using tools such as telnet, rlogin, or SSH. A benefit of using stepping-stones to launch attacks is that intruders can be hidden by a long interactive session. Since each interactive TCP session between a client and a server is independent of other sessions even though the sessions may be relayed, so accessing a server via multiple relayed TCP sessions can make it much harder to tell the intruder's geographical location unless all the compromised servers collaborate with each other and work efficiently. Due to such a nature of TCP protocol, the final victim host can only see the traffic from the last session of the connection chain, and it is extremely difficult for the victim host to learn any information about the origin of the attack. This paper provides a research survey in the area of stepping-stone intrusion detection. Most of the significant approaches developed by far for stepping-stone intrusion detection are included in this paper. These detection methods are put into two categories: host-based and network-based (i.e., connection-chain based), according to whether multiple hosts in the connection chain are involved in the design of detection algorithms. In each category, the detection algorithms are divided into several different subsections based on the key techniques used in the algorithms. At the end of the paper, several important and challenging open problems are proposed in this area.

In Ubiquitous computing small embedded sensor and computing nodes are the main enabling technologies. System programming for such small embedded systems is a challenging task involving various hardware components with different characteristics. This paper presents a file system which organizes all computational and sensory functionality of a sensor node as resources in a uniform name space. It further provides a lightweight and uniform access model for all these resources. This mechanism forms an abstraction from different hardware, makes functions re-useable and simplifies the development on such systems. With ParticleFS a conrete file system implementation on a sensor node platform is shown. Application cases demonstrate sensor logging, an interactive shell, executables, a pipe mechanism and remote access capabilities of the ParticleFS.

We studied Brute-force SSH attacks carried out on six different universities campus networks by using Honeypot Techniques. Brute-force password guessing attacks against SSH, FTP and telnet servers are the most common form of attack to compromise servers facing the internet. A key factor to avoid disruption of these networks is to defend it against Brute-force attacks. We focused on the attempts to gain remote access to our SSH Honeypots Plus Tools and techniques employed. There are striking similarities in the methods used to attack these dissimilar systems. The evidence shows that, pre-compiled lists of usernames and passwords that are widely shared form the basis for brute-force attacks. When the passwords were analysed, it was found that in the event of actual malicious traffic what was commonly understood to be strong password did not protect the systems from being compromised. The data from the study were used to evaluate the efficacy of a variety of techniques designed to defend the systems against these attacks. Table 17 lists some commonly recommendation for the protection of SSH servers.

This paper introduces JitterBugs, a class of inline interception mechanisms that covertly transmit data by perturbing the timing of input events likely to affect externally observable network traffic. JitterBugs positioned at input devices deep within the trusted ...
