Integration Strategies of Various Network Monitoring/Management Platforms with HP Openview Service Desk IT Services Management is a vast field but still it contains broadly three pieces to it: Network Monitoring, Network Management and Service Delivery. Looking at the markets today, it is obvious that the best pitch is made by whatever comes cost effective to the pocket; and with a huge number of Network Monitoring tools coming into the market (some being free/open source), the primary concern is to bring together the three pieces in a seamlessly consolidated form. Breaking this into separate detailed parts, the first bit is the Network Monitoring. Monitoring a network is simple; there are tools which can check device availability, service availability, measure SNMP parameters, even get the process status with agent based monitoring. But adding to this the fact that these network monitoring tools will present the alerts on a platter without much internal correlation, and that these are available on different platforms, the task of Network Management comes into picture as a major concern. Network Management is a consolidated setup in which there is a network being monitored by one or more monitoring tools, and events being received from these are being correlated (if required, in another layer) to form precise and informatory alerts. Service Delivery comes into picture at this point when the information of the alert needs to be sent to a team of engineers who will then need to resolve the issue. This brings us to the integration of these independent pieces, and the layers existing between these. The bottom layer has the Network Monitoring tool. This is what gets the raw data from your network. This may also have the regular syslog enabled for quick fault detection. This usually has a layer of Event Correlation on top of it, which acts as a filtering layer to give the correct and informative alert. The more popularly known Network Monitoring/Management Tools currently available are: Free/OSS • Big Brother • Nagios/Netsaint • OpenNMS • Cheops-ng • OSSIM • MRTG • RRDTOOL • Weathermap • Nino Commercial • HP OV NNM • SMARTS • Aprisma • Netcool • Concord • Proviso • InfoVista • Sitescope • Solarwinds These tools are spread over different OS platforms. And considering that most of these do not come with an internal event correlation, it would be ideal to suggest an external Event Correlation Engine. External Correlation Engines • SEC • LogSerfer • ruleCore • Band Saw These correlation engines usually work on flat files, and parse them based on certain rules applied on them. These rules can then create a list of alerts, which look more English then the events received earlier, and are also not unnecessary.
... for real time monitoring purposes, create alerts, and auditing purposes as well as tools to analyze the log information. Such tools help us a great deal in forensic analysis. It is a welcoming change that organizations realize the importance of auditing computer system activities as well.
The SIEM is a log management system where every network device, server or workstation will send their logs for storage, correlation and analysis. The analysis will provide alerts similar to the NIDS and HIDS. In addition, the log correlation could be used to help track where and when malicious activity has occurred and on what system(s) the activity was seen. The combination of the NIDS, HIDS and SIEM will provide a good array of detection for malicious users, software or unauthorized system access.
NIDS placed at a crucial point within the network to monitor to and from all devices in network. It performs an analysis of passing traffic on the entire SUBNET and matches the traffic that is passed on the subnets to the library of known attacks.
It is also written in pure JAVA and can be used as a standalone library or client
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...
In 1980, James Anderson’s paper, Computer Security Threat Monitoring and Surveillance, bore the notion of intrusion detection. Through government funding and serious corporate interest allowed for intrusion detection systems(IDS) to develope into their current state. So what exactly is IDS? An IDS is used to detect malicious network traffic and computer usage through attack signatures. The IDS watches for attacks not only from incoming internet traffic but also for attacks that originate in the system. When a potential attack is detected the IDS logs the information and sends an alert to the console. How the alert is detected and handled at is dependent on the type of IDS in place. Through this paper we will discuss the different types of IDS and how they detect and handle the alerts, the difference between a passive and a reactive system and some general IDS intrusion invasion techniques.
Hardware, software, support and maintenance costs grow each year with multiple systems in each local region running different types of software and hardware. The application and hardware support teams are larger than could be possible with one integrated solution.
Network Security is the protection of the computer’s network though out the entire infrastructure. It can protect very important information and computer files to help prevent theft, spyware, malware, viruses, and more. Depending on if you have a public or private network, can determine what type of security settings you need for your network. All people are different on what they want to have secured or not, but most people do not know how to prevent people or things from getting in their network. “You must have a general understanding of security terminology and specifications as it relates to configuring hardware and software systems.”(Roberts, Richard M. 599). That quote states that by knowing and understanding security terms and specifics, you can
Although VPN is very popular in the market for networking technology, it may raise some concerns for IT managers. VPN requires an in-depth understanding of public network security issues and proper deployment precautions. The task of choosing and deploying a VPN solution is far from being simple and may require the training of workers in at least the basics...
...mpany up and running through any kind of interruptions such as power failures, IT system crashes, natural or man-made disasters, supply chain/vendor problems and more.
Typically, touching the affected system(s) will not be involved in the initial response. The data collected during this initial response phase includes reviewing of network-based and other evidence. Initial response phase involves the following tasks: • Interviewing system administrators of an incident who might have understanding into the technical details. • Interviewing business unit human resource that may provide a context for the incident, which might have understanding into business events. • To identify data reviewing intrusion detection reports and network-based logs of the incident that would support that an incident has
capacity and performance. However, as networks enable more and more applications and are available to more and more users, they become ever more vulnerable to a wider range of security threats. To combat those threats and ensure that e-business transactions are not compromised, security technology must play a major role in today's networks.
...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.
Networks in organisation are dynamic and complex entities which can be quite challenging to configure and manage. (Kim & Feamster 2013). These corporate networks consist of multiple routers, switches, firewalls, middleboxes and a particular advantage of network management is the ability to monitor the entire business network. As all the devices are interconnected with many event occurring simultaneously, problems with once device can eventually lead and spread throughout...
If you’ve ever been a network administrator, the call you dread the most might be one you receive in the middle of the night by some panicked employee stating that a portion of your critical network has gone down. What troubleshooting options are available to provide answers to your network problem? Besides having a proactive helpdesk that can “read” the mind of your network, an important part of troubleshooting involves using a network protocol analyzer. If you’ve done your research, you realize that there are many choices on the market today that may satisfy your needs but make a dent your company’s pocket book. Plus, you have to factor in training your helpdesk on how to use this new tool and if it will provide some type of return on investment (ROI).
