network management is different from the system administration. In the system administration tasks, all facing a computer system independent. In the case of network administration, if you upgrade your system to a network, it interacts with many other systems. In the hectic world of today, everyone is for the modern network which is much better than the previous challenge. We need security and improved for better network management. Network management often includes activities such as the allocation of network addresses, routing protocols and configuration of authentication and authorization services directory. Often, the maintenance of network hardware includes individual machines, such as drivers and settings of personal computers. It is also the maintenance of certain network: gateways, Intrusion Detection System, etc. The task of the network administrator of network administration implemented. Network Administrator is responsible for network design and security. Design: Designing a network is called the network architecture. Network architecture can be used as principles of design, physical configuration, functional organization, procedures are established and data structures used for planning and construction of a communications network. In this rapidly changing scenario, the term network architecture has also called the classification and differentiation of the distributed computing architecture. To resolve the conflict with a specific theme set of rules that are more secure than a computer via a packet through a data line to send. Safety: Sometimes, security must do more with policy and human resources as a networking theme. A security administrator is usually guaranteed priority in the balance when deciding on a reasonable degree of security and flexibility for users to post their work. A security administrator will seek a balance between these two opposites. Safety clothes like the clothes are designed so they are not too stringent so as not to restrict freedom of movement is not and should not be so vague that it will have on public consent. If the thought of securing a corporate network three possibilities in mind that someone must have access to the corporate network will be maintained: 1) via the Internet. 2) The dial-up. 3) Virtual Private Networks. network management system: network management system is a combination of hardware and software to monitor and manage a network. network elements are controlled by Element Management Systems. Network management refers to activities, methods, processes and tools related to the operation, administration, maintenance and deployment of networked systems. • The company has been held with the network (and services offered by the network) and proper functioning. It includes the monitoring of network problems as soon as possible on the ground, ideally before users are affected. • Body handles monitoring of network resources and how they are affected. It includes all the “housewives”, which is necessary to maintain the network under control. • Maintenance is concerned with the implementation of repairs and updates – for example, if the device must be replaced when a router is a patch for an operating system image, if a new switch is added to a network needs. The maintenance includes corrective action and preventive management of network “works better”, as adjustment parameters of device configuration. • Commissioning is to help the configuration of network resources to a particular service concerned. For example, this could be the establishment of the network, so that a new customer can receive voice services. The changing dynamics of network administration: Perhaps you prefer to work outside the office, for example, on the golf course. If you travel, it would be useful to monitor your servers and network remotely. You’re lucky, there may be a host of utilities that you monitor, diagnose and repair problems, and administrative functions of the distance with a smartphone or mobile device in conjunction with one of your center servers data. Most offers, you can manage passwords, programs for printer connections, e-mail server or database with a tree BlackBerry, Palm or Smartphone Nokia in conjunction with a network server as the rest your network is connected. But Avocent Sonic-Admin, Ecutel IC2 (Infrastructure Command and Control System), Mobile control function of ASG and doubtless many other solutions, many governments have reservations about safety. Security Considerations The idea of network management applications using a wireless device is a dream for many network administrators is true, but it will take some time before the concept takes. In fact, the market potential for these programs is enormous, but security concerns have reduced only a thriving market and the start of benefits is too weak to continue, an analyst Gerry Purdy said Mobile Trax. ”Of course, the demand for this type of application is finally more smartphones feature sets and the software can handle the load required for growth,” said Purdy. “But at the same time, these security devices and applications Risks [in the spirit of the [directors], as when a person leaves the company and has access to the network with his mobile device or when a wireless device may be supplied] the possibility for someone to hack your network with a smartphone. Recognizing that security concerns toughest sell appease Robert Touw, agent in charge of business development mobile solutions group Avocent claims that IT administrators are increasingly buying in both the idea of networking Remote and security that can provide utilities. He also said that even the finance companies, is a major concern for security, now with the utility. Wireless remote control and freedom Above all, administrators have the capacity, wireless and remote network management. “It is the quality of life: all of a sudden you do not give dinner to fix something immediately,” said Touw. “Now, suddenly, you can also do things that used to take 10 minutes in 40 minutes.” For security reasons, said Avocent SonicAdmin offers 3DES encryption and authentication transaction token, if the server only accepts packets valid trademarks recognized. levels of authentication supported by RSA SecurID understand, Sonic Admin user authentication, the authentication device and NT / AD authentication RSA SecurID as well as the integration option. Confidential personal data such as network and application are not stored on mobile devices. In addition, remote administrative measures on the server logs both Sonic Admin and Managed Server. Ecutel IC2 said its software provides six layers of security. The server on which it operates, for example, is sitting at the computer center of the firewall and signals to and from servers and mobile devices are based on a minimum 128-bit encryption. The authentication is an administrative client Web and RSA SecurID is based. There is also a complete audit trail of the time server operating IC2 and IC2 automatically after 30 minutes of inactivity. ASG said users of the interface for managing mobile control of the administrator is required to connect using a PIN number and registration information domain. The systems can also use RSA SecurID, SSL, VPN and wireless solutions third gateway server security. Sensitive data such as passwords, is never stored on the mobile device and an automatic function of time on each wireless device to prevent illegal entry into the network if a wireless device is lost or stolen . According to Purdy, the application will likely be some time provider of directors to convince them that security risks can be minimized. Purdy wrote: “It’s just a question of this society that the word [the utilities] are safe and they work.”

Can you guess which is the amount of money lately for network marketing? Social Networking! I’ll explain why, but we’ll take a look at how it began. First there was MySpace and Facebook, two huge giant social networks. Network Marketers have joined them to market their opportunities through these sites. It is a great way for additional exposure, although the network members are not targeted. However, the value of marketing on MySpace and Facebook is in freefall. This is due to the massive release of new products and niche focused social networks. The fact is that this year alone, I have a growing number of professional social networks for traders of the network-oriented start seen increasingly popular. To name a few: TalkMoola. com, ZenZuu, Friendswin, Yuwie and Wowzza. Some are more direct matches, and even AdLandPro Ryze. Frankly, I can not even be the slightest surprised a bit more starting this year – is just how it is catching up! He is also obvious why they’re so popular with marketers network, because there is no better advertising than targeted advertising. To expose your business opportunity, the system or product to other network marketing is simply the most effective thing to do. Once you connect a network marketing agent, they have already had their foot in the door and some knowledge of the industry and can greatly help your business. However, if a random person like MySpace and connects to your company, they are not as valuable to you, because they probably have no idea what they are or what network marketing is done of. So if network marketing with the possibility of joining a social network full of network marketing, it is almost a breeze are invited. Just to clarify why I’m doing, “said almost. . . Because all network marketers have the power of social networks yet, or are captured, how to properly use social networks to explode their business. But the possibility of further explained themselves and their activities to other people like you are extremely valuable and profitable for most. The old method of network marketing is out, and I see the future engagement of social marketing through professional social networks. However, many of these new companies of social networks are incentives for those who join. These range from revenue sharing and pay affiliate commissions and other direct MLM plans. This support network, this new social enterprise, is the increased awareness and exposure they deserve experience. All professional social networks are not the same. Here are some things you look for when deciding which one to use in the detection of yourself and your possibilities. 1) Something specific target or extreme? In the search to find information on your social networks, if those involved in the type of social network of people interested in what you offer, or you’d mind. This means that if you are looking for a marketer of network for a chance to other computers on the network, so people are marketing in the social network in question, must necessarily be of network marketing. Is the social network you belong to members think seeking a date or love? If the social network includes these niches or nothing at all to do so undermines the potential of this network for you. However, if the network marketing social network and one of business opportunity seekers, then it is an incredible resource for you. 2) Are there any restrictions on how to communicate with your friends in the crowd? Increase your friends, or list of contacts on social networks is an important thing that you do to maximize exposure and reach. This means accepting invitations to add social network and also trying other people like you in your network of friends. More list of friends more active, you will be and the more people will be at the heart of what you have to say. It can also mean more people you send messages through the social network. Some social networks limit the number of people you will be able to send a message at a time. Suppose you have 200 friends, but you’re limited to sending only 30 people per message, and you can use a bulk message per day. Well this is a very critical limitation and even more if you have a network of friends much more. On the other hand, some social networks will give you unlimited friends and them to a newsletter or a message to all your friends at once at any time with ease. That’s what you should look, because if you have 100 friends, 1,000 or even 10,000 to send a message to all as easily as if you were in the shipment possible. This means potentially huge burden on you. If you wish, you can even consider for a moment, as targeted contact list prospects! However, I warn you send too many unsolicited messages to your friends, you should try to contact them and send them as much quality information as possible and instead present then easily what you have to offer. If you regularly send what they consider as spam, they will simply block or remove them from their network of friends is that properly with the important social network. be 3) The members paid for free, or both? Another factor is the true quality of the membership base. If membership is usually free, then they are less likely to buy loans. However, if the membership of all paid and everyone is used to pay for part of the social network, are members of the highest quality you in contact with, because they get money to invest in you can work with. Mixed is not in order, but if this factor as important as the first two. 4) What are the incentives of the other side? It is the least important, but it is worth mentioning nonetheless. Other incentives could include compensation, such as sharing revenue, affiliate commissions, or a kind of matrix structure. It could also be other services provided with your payment of membership fees, such as training, tools or other bonuses. Remember, even if they do not offer very good incentives, but the rest of the factors mentioned above, I would love to join again. For the moment there is not a huge selection of professionals targeted social networks, but I am convinced that the future is true for more and more are available. I personally use “and any social network, because the extra exposure for me, and any additional burden, as is always a good thing. But in choosing the most active in the selected networks, you might want the above factors. take into account that I have established many good relationships, learned a lot, learned a lot and benefited a lot from the relationship within social networks. They should at least some of each social network advatange professional to take, even if only to create a profile to gain some additional visibility. If a niche social network, like the mind closely related, even then you should definitely open to further promote actively using the network. The benefits can be enormous.

1 Introduction Ad hoc networks are a new paradigm of wireless communications for laptops (which we call nodes). In an ad hoc network, there is no fixed infrastructure such as base stations and mobile switching centers. mobile nodes to communicate within each radio coverage of other directly via wireless connections, while those who are distant from each other nodes based on messages before the router. node mobility in an ad hoc network causes frequent changes of network topology. On the tactical military operations are still the most important The use of ad hoc networks today. For example, military units (such as soldiers, tanks, aircraft, or), equipped with wireless communication devices could create an ad hoc network when they travel to form a battlefield. The ad-hoc networks can also be used for law enforcement and emergency rescue operations. As an ad hoc network can be deployed rapidly with relatively low costs, it is an attractive option for commercial uses, such as sensor networks or virtual classrooms. Safety First 1 Goals Security is an important issue for ad hoc networks, security, especially for applications. To ensure an ad-hoc network, we consider the following attributes: availability, confidentiality, integrity, authentication and non-refoulement. Availability ensures the survival of network services despite denial of service attacks. A denial of service may at any level of an ad hoc network can be started. On the physical layer and Media Access Control, an opponent of interference papers dealing with the discomfort of physical channels. At the network level, it could disrupt an opponent of the routing protocol and disconnect the network. At higher altitudes, an opponent could throw the high level services. Such an objective is the Key Management Service, an essential service for all security frameworks. Confidentiality ensures that certain information is disclosed to unauthorized persons. network transmission of sensitive information, such as strategic or tactical military information requires confidentiality. Leaking information to the enemy could have devastating consequences. routing information must remain confidential in some cases because the information could identify the enemy and find their targets in a battlefield value. ensures the integrity of a message is never transmitted damaged. A message has been because of benign failures, such as radio propagation loss or damage due to malicious attacks on the network. Authentication enables a node to guarantee the identity of communication nodes peer. Without authentication, an adversary could masquerade a node, so that unauthorized access to resources and sensitive information and disrupt the operation of other nodes. Finally, non-repudiation ensures that the origin can not deny a message that the message sent. No release is useful for the detection and isolation of compromised nodes. If a node A is a false message from a node, B non-repudiation can convince B to acknowledge with this message and other nodes, the risk B. There are other security objectives (eg approval), which are relevant for some applications, but we will not pursue these issues in this document. First 2 Challenges The main characteristics of ad hoc networks have both challenges and opportunities in achieving security objectives. Firstly, the use of wireless connections allows ad hoc network vulnerable to attacks by replay link passive listening post impersonation active, and the distortion of the message. Eavesdropping might give access to secret information opponent, respect for confidentiality. Active attacks might allow the adversary to delete messages, to inject erroneous messages, changing messages and an output node, and therefore violates the availability, integrity, authentication and non- repression. Second, nodes, roaming in a hostile environment (like a battlefield) physical protection relatively low, have a substantial likelihood of a compromise. Therefore, we must consider not only attacks outside a network, but also consider attacks inside the network will be launched by compromised nodes. Therefore, to achieve high survivability, ad hoc networks must have a distributed architecture, without two central institutions. The introduction of a central place in our security solution can lead to a significant vulnerability, that is, if this centralized entity is compromised, then the whole network is compromised. Third, an ad hoc network is dynamic due to frequent changes in both its topology and its members (ie, nodes often join and leave the network). Trust between nodes also changes, for example, if some nodes are detected as a compromise. Unlike other mobile wireless networks, such as mobile IP [21, 48, 34], nodes in an ad hoc network can be dynamically join with administrative sectors. While not a security solution with sufficient static configuration would be. It is desirable that our security mechanisms to adjust on the fly to these changes. Finally, an ad hoc network is composed of hundreds or even thousands of nodes. The security mechanisms must be scalable to handle such a large network. First 3 routing protocol and threats routing protocols for ad hoc networks are still actively looking. There is no single standard routing protocol. Therefore, we want to capture the common security threats and provide guidelines to secure routing protocols. In most routing protocols, routers exchange information about the topology of the network to establish links between nodes. This information could be a target for malicious adversaries who want to reduce the network has become. There are two sources of threats to routing protocols. The first comes from outside attackers. By injecting false routing information, the reproduction of old routing information, or distorting routing information, an attacker could successfully load sharing network or introduce excessive traffic in the network by retransmission and inefficient routing. The second and come to the severe nature of the threats from compromised nodes, advertising false routing information to other nodes can. Identification of erroneous information, it is so difficult just have to be signed routing information of each node does not work, because compromised nodes are able to generate valid signatures with its private key. In defense can protect against such threats the first node routing information the same way they protect data traffic, namely the use of cryptographic systems such as digital signatures. However, this defense against attacks compromised servers is inefficient. Worse yet, as we have explained, we can not overlook the possibility of compromised nodes in an ad hoc network. Detecting compromised nodes by routing information is difficult in an ad hoc network by dynamically changing topology: when finding a piece of routing information is not valid, the compromise by a node, or it would could generate invalid may be due to changes in topology. It is difficult to distinguish the two cases. On the other hand we can use to obtain specific properties of ad hoc networks, secure routing. Note that the handle of routing protocols for ad hoc networks must be overcome routing information to reflect the topology changes dynamically. False routing information generated by compromised nodes could, to some extent, are also outdated information. While there is enough correct many nodes, the routing protocol must be able to find ways to get around these nodes compromised. The ability of routing protocols is usually based on collective redundancies inherent – disjointed, perhaps, the connections between nodes – in ad hoc networks. 2nd Key Management Service We use cryptographic systems, such as digital signatures, to protect the routing information and traffic data. Application of these systems generally requires a centralized management service. We take a public key infrastructure because of its superiority in key distribution and implementation of integrity and of non-refoulement. effective secret key systems used to secure communications of other node to authenticate each other and after a session key shared secret. In a public key infrastructure, each node has a public / private key pair. The public key can be distributed to other nodes, while the private key must be kept secret for individual nodes. This is a trusted entity called certification authority (CA) [11, 47 and 26] for key management. The CA has a public / private key pair, with its public key is known, each node, and the keys to sign certificates bind public nodes. The trusted CA must be online to reflect the outstanding bonds because the bonds may change over time: a public key can be revoked if the owner node is no longer trusted or leave the network, a node can renew its key pair periodically to reduce the likelihood of a brute force attack on the success of its private key. It is problematic to create a Key Management Service with a single CA in ad hoc networks. Net sales for the security of the entire network, is a vulnerable point in the network: If the CA is unavailable, can not the current node public keys of other nodes or to establish a secure communication with others. If the CA is compromised and leaks its private key to an adversary, the adversary can then sign up incorrect certificate with the private key on each node to issue or revoke a certificate. A standard approach to improve the availability of a service is replication. But a simple replica of the AC is the vulnerable service: Compromise of a single replica, which holds the key to private service, could lead to the collapse of the entire system. To resolve this problem, we distribute the trust to a set of nodes sharing the node, the responsibility for key management. 3rd Push! Photo: Photo Sharing informal ad hoc networks Like the ubiquitous mobile phone cameras changed the practice of photography. Camera phone pictures are usually taken by an exchange in the soul. Meanwhile, the public online photo sharing is becoming more popular with sites such as Flickr. Push! The photo is a photo sharing for mobile applications where images can be publicly and immediately accessible to anyone nearby. The application also automatically search for files on devices in the vicinity of interesting photos and found relevant. Push! Photo shows how it is possible to share digital photos as easy as photo paper. Shoot! Submit! Discover! Enjoy! A third THE PUSH! PROTOTYPE PHOTO The current prototype of Push! Pictures, photos can be made public, and users can browse their own collections and those of others in the region. For devices are close to each other, they automatically launch every other collections of photos from public research Photographs relevant to a car. These photos are a multi-picture slide show, which is extended as shown in the photos are new. beat you to browse photos of an event in a particular image, the user can click on this image in the slideshow. The application will then download all the pictures from nearby devices during this event. This way, if a user can find an interesting picture in the slideshow, they can easily find other images of the same event. Deciding What are two photos of the same event, information about who is the opposite and used the time of the shooting. The application uses a discovery service for other devices if they are within the WiFi zone is still demand to know who else (push! Photo) is clear at once. As the photo is taken, the image resulting from this information over time and the identity of the photographer. The current prototype is an application running on Pocket PCs with wireless cards and external cameras SD 2 THE third related In earlier work with Push! Music [2 files] music were known as media agents that activate independently replaced if you copy between devices on a wireless ad-hoc. The media are trying to find their agents Path of potential listeners to respond to a user, and how a song is automatically copied to the play list. In this way, users discover new music, while listening passively. Other projects have looked at the photo sharing Mobile. Davis et al. mm2 at the notion of co-presence used to share the decision with which [to simplify 1]. Photos can be automatically entered in a central Web server, where access to share photos downloaded receiver. Kohno Rekimoto and instead decide to GPS information and time stamps, if the images are of the same event or not [4]. It is used to enable users to navigate easily use each other’s picture while standing in a group as a subject of discussion. The system also users drag and drop images between themselves and others. In contrast, Push! Photo sharing is a simple mobile use to simplify common view, and using context and marking automatically find you interesting and relevant photos 4 Conclusions In this paper we have analyzed the security threats facing a network ad-hoc and put the objectives of security policy to achieve. First security applications in sensitive areas to require ad hoc networks, the high level of security on the other hand, ad hoc networks inherently vulnerable to security issues, attacks. Therefore, security mechanisms for ad hoc networks are indispensable. The nature of ad hoc networks presents both challenges and opportunities of these mechanisms. This document focuses on how to secure routing and how to create a secure key management service in an ad hoc networking. These two questions are fundamental to achieving our security objectives. In addition to standard security mechanisms, we use redundancy in ad hoc network topology and the use of diversity coding on multiple routes tolerate benign and Byzantine faults. To build a highly available and highly secure key management service, we propose to use the first threshold cryptography to distribute trust among a group of servers. In addition, our service offers key management and share original services to ensure proactive security and adapt to changes in the network in a scalable manner. Lastly, by relaxing the requirement of consistency on the servers, not the end of our services are based on assumptions synchrony. These assumptions could lead to a security vulnerability. A prototype of the function key management has been implemented, demonstrating its feasibility. This document represents the first step of our research to analyze the security threats in order to understand the security requirements for ad hoc networks and identify existing technologies and propose new mechanisms to secure ad hoc networks. More work must be done to these security mechanisms are in use to investigate ad-hoc network and the impact of these mechanisms on the safety performance of the network. 5 Acknowledgements I want to thank my friends for their valuable contribution to this work.
