What Is a Traffic Analysis Attack?

The times when it was enough to install an antivirus to protect yourself from hackers are long gone. We actually don’t hear much about viruses anymore. However, nowadays, there are many different, more internet-based threats. And unfortunately, you don’t need to be a million-dollar company to become a target of an attack. Hackers these days use automated scanners that search for vulnerable machines all over the internet. One such modern threat is a traffic analysis attack.

The 95th Percentile: How to Manage Capacity Before You Run Out

One of the largest challenges with network bandwidth metering is the way traffic flows. Traffic comes in bursts. It’s never a constant, predictable stream of data you can measure once, spec hardware for and be done with (wouldn’t that be nice?!). Instead, you need to account for the dynamic nature of bandwidth utilization and its impact on performance. You’ll never be able to predict every burst of traffic your network experiences.

How NaaS Can Support Development and Testing Environments

The widespread adoption of the cloud has transformed the way applications are developed just as much as it has transformed the way they are deployed and consumed. In this blog we look at how Network-as-a-Service (NaaS) can help developers support the complete application lifecycle by unlocking the value of PaaS (Platform-as-a-Service).

Monitoring Load Balancers with Grafana

Load balancers play an important role in distributed computing. With load balancers, you can distribute heavy work loads across multiple resources, which allows you to scale horizontally. Since they are placed prior to computing resources, they need to endure heavy traffic and allocate it to the right resources fast. For this to happen, monitoring the health and performance of load balancers is key. In monitoring, visualization helps users to view various metrics quickly.

Monitoring Network Switches with Grafana

In monitoring, a target system or device is a deciding factor in designing your monitoring stack. You will have to consider various aspects starting from how you want to collect data in what frequency to how you want to surface metrics to end users. You will have to take this strategic approach when you want to monitor your network infrastructure. In this article, we will discuss how Grafana, an open-source visualization tool, can help you to monitor network switches.

What Is Network Monitoring?

Network monitoring is the practice of making sure the network as a whole, functions optimally by keeping a watch over all endpoints of a network, which is the heart of any business’s routine functioning. Any discrepancy in the form of a breach or slowdown could prove costly. Proactively monitoring networks helps administrators identify and prevent any potential issues that could occur at any time.

Root cause analysis using Metric Correlations

As complexity of systems and applications continue to evolve and change, the number of metrics that need to be monitored grows in parallel. Whether you’re on a DevOps team, an SRE, or a developer building the code yourself, many of these components may be fragmented across your infrastructure, making it increasingly difficult to identify the root cause when experiencing downtime or abnormal behavior.

Difference Between IPv4 and IPv6: Why haven't We Entirely Moved to IPv6?

IPv4 and IPv6 are the two versions of IP. IPv4 was first released in 1983 and is currently widely used as an IP address for a variety of systems. It aids in the identification of systems in a network through the use of an address. The 32-bit address, which may store multiple addresses, is employed. Despite this, it is the most widely used internet protocol, controlling the vast bulk of internet traffic. IPv6 was created in 1994 and is referred to as the "next generation" protocol.

Monitoring HAProxy Logs and Metrics with Sumo Logic

HAProxy is one of the world’s most innovative and highest-performing load balancing solutions. The load balancer is critical for enabling high availability and supporting the dynamic scaling of infrastructure within modern applications. Because of its importance, engineers need tools that can quickly and effectively diagnose any problems with the load balancer if they arise.
