Increasingly corporate networks are the targets of massive virus attacks. These malicious attacks often cause the corporate networks to go down leading to lost business days. Network dependant enterprises can't afford to suffer such attacks, as the financial implications are quite high. A sound tool that lets you detect the onslaught of any virus attack or worm attack instantly is well in order.
Scenario:
A Network Engineer observes anomalous peaks in network load at the start of business day. He views the traffic report and observes spikes in the traffic pattern.
He suspects a possible worm attack that has been known to be affecting computer networks elsewhere. To confirm his suspicion he views the Troubleshoot report in the NetFlow Analyzer.
He finds unusually high traffic on port UDP 1434, which is characteristic of a SQL Slammer Virus attack. Now, he can drill down to see the IP addresses from which this attack is originating and also the list of IP addresses that are infected.
He can now block the source of this attack and then proceed to apply the appropriate patch on the infected IPs.
NetFlow Analyzer helps network managers to quickly identify the cause of attacks and take immediate corrective action to contain any possible damage.
As a network manager you need to be on top of your network to be in control of the day-to-day happenings in your network. Especially, with more and more businesses being increasingly dependent on the internet, it is very vital that you are in total control of your network.Any network outage has to be quickly attended to and fixed right away. More importantly any network incidents has to be pro-actively attended to. NetFlow Analyzer with its proactive alerting mechanisms ensure that you are informed of any network exceptions as it happens. Also the drill down features let you quickly pin down the cause of any network problems and troubleshoot faster.
It is also very essential that you ensure your business critical applications are not starved off bandwidth while non-critical activities like music downloads hog the available bandwidth. By giving you an indepth visibility in to your network and the bandwidth usage statistics you can appropriately set QoS policies. It is also possible to categorize applications that consume bandwidth by port, protocol and IP address. This way you can be fully empowered to ensure that the business critical applications always have the required bandwidth.
As a network administrator you need to have all the reports to take the right decision. Especially when it comes to bandwidth capacity planning decisions the stakes involved are high and even a small mistake can cost huge money. NetFlow Analyzer with its long range historical reporting lets you take the right decisions. Also as a network administrator you need to have periodic reporting to understand how the network is performing. NetFlow Analyzer's automatic report generation feature at scheduled time periods help you with just that.
Should you need any specific information at any point in time, you could just access the application for a quick snapshot. NetFlow Analyzer's dashboard presnet you with all the vital metrics you need to eb aware on as an administrator. You could drill down on it for any further infromation on any specific element of your network.
