One of the keys to a secure network is to implement proper Network Management. Network Manage encompasses five domains. Those five domains are known as configuration management, accounting management performance management, fault management and security management. Utilizing these concepts is paramount for maintaining a secure network. Configuration management is the process of obtaining data from the network and using that data to manage the setup of all managed devices. The goal is to monitor network and system configurations so that the effects on network operations can be tracked and managed. In order to accomplish this function you must first gather network data. Once the data is gathered it must be used. Finally, all of this data must be stored. The data gathered for configuration management will identify in detail the total configuration such as the hardware, firmware and software that is being implemented on the network. This data can be collected manually or automatically. The manual method can be very time consuming, however during initial network setup this may be the only option. Gather data automatically via a software program would be the preferred method once a network is in place. Regardless of which method is used, enough network information needs to be gathered in order for it to be useful. Using the data collected in order to make or recommend changes to the network is the next step. All networks will need existing hardware to be upgraded at some point. New hardware will be purchased, obsolete hardware will be replaced and modern equipment will need to be installed. This goes the same with software and the inherent vulnerabilities in them. This is where the hard work of gathering the data pays off. This dat... ... middle of paper ... ...de traffic flow control. You can also use ACLs to decide which types of traffic are forwarded or blocked at the router interfaces. But one of the most important reasons to configure ACLs is to provide security for your network. The final step in security management is maintaining secure access points. Keeping the security measures up to date is a formidable task. The job requires a large amount of time and resources - yet it is essential. The key to preserving network security is finding both potential and actual security breaches. In conclusion, configuration, accounting, performance, fault and security management are a good baseline for maintaining and securing your network. These methods can help find loopholes, but no technique can guarantee security. The job of maintaining a secure network falls primarily on the people in the organization.
This can give you the IP address, MAC address and vendor on machines. Then one runs the Nmap -A xxx.xxx.xxx.xxx* command with the same address range to obtain the operating systems on those same range of machines and what application version it is. This also gives the open ports and what services are running on them. Now the IP, MAC address, vendor, port information, services, Operating system and the version are known. After all this information is known, one can utilize a mapping tool such as Solar winds that can give an actual picture representation of the network to visualize things. Next is enumeration to discover more specifics such as user accounts, group settings and application settings. Depending on the OS, version and if NET Bios is enabled, one could use null sessions to find lists of machines, shares, users, groups, and users/host ids. Using the Windows command line, type:
During 2003-2007, cisco registered a top durable top line growth period. They take a strong ability to manufacture and design new products with how the new world processes information. They have strong strategic industry partners and they have a good customer relationship. Cisco is a company that focuses on their core competencies. When they monitor and manage more than 10,000 devices, it becomes time consuming. Even with these problems cisco systems does have many strength...

This is only a small part of the prevention of infiltration of your network and computer. If one desires to learn more, go above and beyond and continue to learn on how to keep your network secure.
Ultimately the end users turn out to be the weak link in the security chain as they ignore the latest security trends and install outdated devices that do not support the latest security features. An example would be that of an outdated wireless router that does not support WPA encryption. By proposing a simple solution that lets the users configure their wireless access points for best possible security, the problem can be nipped in the bud.
It has been demonstrated that a number of interoperable systems must be implemented to fully protect a network; a strategy known as Defense in Depth. Due to the multitude of security devices and device categories available, it can be very difficult to identify the correct tools for meeting security goals. Using the Defense in Depth strategy will require an understanding of the interactions between devices occuring within the network.

According to ITIL best practices, Configuration Management process activity needs to be established to obtain the configuration information and data from different sources or third parties. Figure 4.1 illustrates the activity model for configuration management process. Therefore, the following activities ensure that the data or information stored in CMDB is qualitative and reliable.
This paper describes the basic threats to the network security and the basic issues of interest for designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers
...vantage of the overall network design and implement usable subnets with virtual local area networks. Use encryption and encapsulation to secure communications of public segments to enable extranets and cross-Internet company traffic. Use items such as intrusion detection systems and firewalls to keep unauthorized users out and monitor activity. Taken together, these pieces can make a secure network that is efficient, manageable, and effective.
Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.
Corporate Networks in organisations can be complex structures that “requires a great deal of attention” (Clemm 2007). Even small companies can have quite complex networks that are a considerable investment to the business. The notion that corporate network management is a cost to a business rather than a continual beneficial investment is a naive assumption that requires further investigation to the benefits that network management brings. Clemm (Clemm 2007) states in his text that the ultimate goal of network management “is to reduce and minimize total cost of ownership”, improving operational efficiency and lowering cost. Clemm (Clemm 2007) also notes that “Network Management is not just related to cost and quality”, which will be an continual concept presented throughout the report. The report will address key issues with corporate network management and ultimately argue and justify that corporate network management must be seen as a positive benefit to the business and not as a continual expense. The supporting articles will also provide sound evidence that networking is crucial to a business’s processes and production which can be seen from the OpenSSL Heartbleed Security vulnerability fiasco (Nieva 2014) or the QANTAS Amadeus system failure (Heasley 2012).
Network management planning and security planning involves identifying the best and most appropriate systems and hardware that the firm can use to better manage network and plan security systems. Therefore, the management required me to examine the best software and hardware systems in the market place that the company can adopt to enable it to manage the network and security. The management required me to advice on the implementation procedure of various plans that are going to be adopted. My responsibility also involved finding out or predicting the impact of the plan on the future operations. They required me to evaluate the challenges the company might face while adopting the changes in the network management plan and security plans.
...departments makes it easier to keep a more secure network. Third ACL Layer is focus on allowing and denying access between hosts on networks. ACLs are written on both routers and firewalls. The key on creating strong ACLs is to concentrate on both ingress and egress ACLs.
A critical part of network planning involves setting up of security mechanisms. Deploying the network with security configuration provides superior visibility, continuous control and advanced threat protection across the extended network. Additionally, security procedures define policies to monitor the network for securing critical data, obtain visibility, mitigate threats, identify and correlate discrepancies.
In developing this Network Management System, we use Visual Basic 6 as our tool. We choose this particular application because it is easier to work with as our entire group member familiar with Visual Basic 6.
