You bet. On average, businesses are losing R84,000 for every minute of unplanned network downtime (Gartner). That’s well over R4.5M every hour. How long does it take your IT team to find and fix issues?

The issue that grinds your business to a halt could be an application or server issue, an unknown virus, a BOT or DDoS attack a disgruntled employee wanting revenge or simply an unknown event that disrupts the network and magically disappears. What can be done to prevent or at least detect these many diverse, unusual and challenging issues?

Things to consider:

Dynamic Network Mapping – See who is up, who’s down, response times, etc Mapping the network and drilling down to maps of specific locations and connections allows us to quickly pinpoint issues. If a router in Cape Town is acting up, you can instantly see the problem, where it is located, the impact it can have on the network, and what we need to do to fix the issue.”

Anomaly Detection – Detect any abnormal activity on the network, Worms, Virus’s, DDoS attacks, repeat password attempts, high or low bandwidth usage, data seepage, abnormal response times, unknown or unauthorized IP addresses, in fact anything that is not normal. Most companies rely on legacy IT systems, consisting of perimeter security and endpoint protection. However, they dismiss the significant infrastructure located between these two areas. In the world where threats have more opportunities than ever to bypass traditional solutions and sneak in, where 70% of attacks come from an internal network, this approach is not enough anymore. How do you secure your systems and data from sophisticated, ever changing threats that are undetectable by traditional solutions?

Application Performance Monitoring

Applications are usually the only part of the IT environment visible to the end users. So that ensuring a high quality user experience is crucial for application-driven business. For years, transaction simulations and software agents on servers were only resource demanding ways how to achieve this. Network traffic monitoring proves that there is a better way how to identify and resolve performance issues and enhance user experience.

Network Traffic Monitoring

Do you know who communicates with whom, when, how long and how often in your network? Flow based monitoring, NetFlow, IPFIX, sFlow, jFlow, etc have been developed to provide these answers and manage corporate infrastructure with confidence. By using Flow based analysis, administrators get an instant insight into network traffic structure to check its utilization, to find stations most loading the crucial connections, to plan capacity properly or control QoS.

All of the above functions are available in one product, FlowMon from Invea, developed for GÉANT in Europe linking most of the research institutions and universities and hosting over 65 million users FlowMon is the most powerful Network Monitoring and Security tool available and is used by many Government agencies, Police and Military organizations, worldwide. Now available in South Africa from Soba Vigor.

FlowMon is comprehensive solution for monitoring of network infrastructure, based on an observation of IP data flow (NetFlow/IPFIX). The technology provides overall view of network traffic within fixed, mobile or cloud infrastructure, details of every single communication as well as details about who, where, for how long, how often, using which protocol and which service, or amounts of data transferred during the communication. FlowMon is the only European solution using Network Behavioral Analysis (NBA) as identified by analytical agency Gartner.

The solution consists of powerful dedicated probes, collectors and NBA based module ADS (Anomaly Detection System), which detects both known and unknown security threats (attacks on network services, infected hosts, network traffic anomalies etc.). FlowMon solution may be extended by additional modules such as DR (Data Retention) to fulfill governmental law requirements not only in Czech Republic. Furthermore it is module TR (Traffic Recorder), recording chosen portion of traffic, including contain of packets.

Flow Monitoring – Next Generation Network Monitoring (NetFlow/IPFIX)

Network Behavior Analysis – Next Generation Network Security (NBA, NBAD)

IP Data Retention for ISP – governmental law fulfillment

FlowMon Traffic Recorder – recording of whole network traffic (L2-L7)

As of today, internet service providers require solution of a new generation, which provides faster and more comprehensive overview of network traffic and security of both their networks and their customer networks. Width of bandwidths is growing as well – from 10Gbps, 40Gbps, 80Gbps up to 100Gbps and the only solution delivering overall network monitoring is IP flow monitoring.

FlowMon solution detects anomalies or security incidents during the occurrence on the network thanks to ADS module. Through a collector the data is stored for the required period (for tracing incidents or forensic analysis). The whole solution can be fully integrated into SIEM solutions (Syslog, CEF).

Detection of these events:

• Attacks (port scanning, dictionary attacks, DoS, Telnet)
• Network traffic anomalies (DNS, multicast, high variability of communication)
• Anomaly behavior of IP addresses (change in behavior profile)
• Malware (viruses, spyware, botnets, communication with blacklisted addresses)
• Mail (outgoing SPAM, illegitimate mail servers)
• Operation problems (delay, overcapacity, reverse DNS records, service outages)
