- Traffic tools enable St. Luke’s to find network bottlenecks
When St. Luke’s University Health Network migrated to a new data center in 2011, it also started implementing technology from security vendor Savvius to improve the troubleshooting of its information systems.
Before using those capabilities, its hospitals didn’t know if a network or information system was having trouble until it manifested with slow response times, typically indicated by phone calls from users to the information technology department for the system, based in Bethlehem, Pa., and operating seven hospitals and a network of 300 physicians.

- Gazing ahead: Security predictions, Part 6
As more IT infrastructure transitions to become cloud-based and accessible from anywhere, hackers will focus on targeting browsers as the weak point. Browsers are essentially the operating system today, no matter whether you are using Windows, Mac OS or Linux. Employees spend most of their time in the browser, talking on Hangouts, drafting documents on Google Docs, and using multiple plug-ins. It's a very large attack surface that hasn't been fully used by hackers, but that is about to change. And once hackers find a vulnerability within a browser, they'll have access to everybody who uses Chrome as their browser, regardless of OS. This will be a nightmare for IT security professionals, unless they are using incredibly sophisticated analytics tools.

- How 802.11ac Wave 2 Complicates WiFi Troubleshooting
For all intents and purposes, 802.11ac has been a great success. Since its approval by the IEEE nearly two years ago, the WiFi standard has introduced thousands of compatible routers, laptops, mobile phones, IoT devices and other wireless gadgets operating at blazing speeds in the 5 GHz band. And the revolution has just begun.

- Examining the scene of the (cyber) crime with network forensics
Enterprise security teams have historically spent most of their time, human resources, and money on defences like firewalls and Intrusion Detection Systems (IDS) to protect and monitor the security of their networks. However, a quick look at the news will tell you that these barriers are far from foolproof. With breaches becoming more common (and costly), enterprise teams are turning to tools that help them respond quickly to security incidents as soon as the attack has been discovered. Network forensics looks at information such as log data, network flow, and packet data to answer the question ‘how did the attackers get in?’

- Cyberattack CSI: Forensics investigations should start with pre-attack analysis
Enterprise security teams have historically spent a lot of time, human resources, and money on developing strong defenses such as firewalls and deploying equipment and software like intrusion detection systems (IDS) to monitor the security of their networks. In fact, most enterprises have built an impressive level of expertise when it comes to configuring and monitoring these tools.
Nevertheless, as we all know, breach detection and prevention technologies are not foolproof. Given attackers’ success in penetrating standard corporate defenses, enterprise teams are looking beyond these well-known technologies and incorporating better tools and training that deal specifically with incident response once attacks have been discovered.

- The LTE-U Vs. WiFi Debate
If carriers use unlicensed spectrum, it may not be the WiFi disaster that some expect.
LTE-U, an emerging technology that aims to reduce cell phone data congestion by offloading traffic onto unlicensed spectrum, has been a hot topic in the wireless world. Carriers like AT&T, T-Mobile and Verizon are proponents of rolling out this technology while wireless companies and coalitions like the Wi-Fi Alliance worry that it will degrade WiFi performance. In fact, they have gone so far as to say that LTE-U would be disastrous. Is this just hype, or a valid concern? It may be too early to tell, but let’s look at what we know so far.

- Optimizing Network Security With Packet Intelligence
Enterprise security teams devote an incredible amount of resources to monitoring and defending their networks. Everyone knows there are professional grade tools that can monitor networks 24×7 providing detailed information about usage as well as enabling the in-depth examination of captured traffic once an Intrusion Detection System (IDS) has identified an activity that needs to be investigated.

- The Value Of The Packet
Networks are complex, and always changing. Trying to troubleshoot them – or find the cause of a breach – can be a huge undertaking, but this task can be made much easier if packet data is available. You can learn a tremendous amount from a single data packet. Just from the header you can determine who the sender and receiver are, the general characteristics of the communication – whether TCP (receipt acknowledgement requested), UDP (just make the best effort), or RTP (time-critical so resending just isn’t practical), and even a clue about the packet contents based on the port used to send the traffic, like Secure or Remote Shell (SSH or RSH), HTTP, and thousands of others.

- The top three network alerts you need to monitor. Hint: it’s all about utilisation
Every network is different, but they all share similar challenges. For the engineers and IT managers tasked with monitoring, analysing and troubleshooting corporate networks, there are a multitude of alerts and alarms that can be triggered by abnormal activity.
In the case of organisations with large, distributed networks and multiple local branches or smaller offices, it can be even more difficult to isolate and remedy problems from a remote location. Sending dedicated staff to troubleshoot at those offices is both time-consuming and costly.

- Network Forensics at 40G and 100G Speeds
The 40G and 100G market will generate tens of billions of dollars in revenue in the next few years according to a recent Infonetics market forecast (link is external). Growth in traffic, which some analysts (link is external) estimate will reach 50 to 60 percent annually, enables new opportunities but also puts enormous pressure on networks and creates new challenges.
Network forensics is one of these new challenges. Although network forensics is most commonly associated with investigating security incidents and breaches, it is also very valuable for providing visibility into network activities, troubleshooting issues quickly and diagnosing common network problems such as connectivity, unexpected change in utilization, or poor VoIP call quality.

- Packets still rule when it comes to useful network traffic analysis
It seems obvious to say that network traffic is growing in volume and speed. And of course, it means that IT staff are always looking for faster ways to detect any problems that would interfere with the reliable movement of data, but simply monitoring traffic flow has proven to be insufficient.
