At 15:51 UTC yesterday, the digital media began to boil over: Facebook and its affiliated services WhatsApp and Instagram were all down. Their DNS names stopped resolving and their infrastructure IPs were inaccessible. It was as if someone had “pulled the wires” of their data centers all at once and disconnected them from the Internet.At the end of the day, Facebook revealed some details of what happened internally. Today, it went further in the explanations. Someone, during routine maintenance, issued a command intended to assess the availability of global backbone capacity, which unintentionally took down all backbone connections, effectively disconnecting Facebook’s data centers around the world.
To ensure infrastructure is protected against cyberattacks, organizations are increasingly adopting IT infrastructure monitoring tools. This market is projected to grow in revenue from $16.1 billion in 2020 to more than $64.5 billion in 2031. And one segment that is becoming increasingly popular is Monitoring as a Service (MaaS), particularly following the growth in remote working and telemedicine caused by the Covid-19 pandemic.MaaS offerings consist of various tools and applications designed to monitor a particular aspect of an application, server, system, or any other IT component. an approach that aims to ensure maximum availability, security, and performance of IT assets through 24×7, real-time monitoring contracted under a usage-based billing model.
Since March last year, the 14,000 students at the Pontifical Catholic University of Rio Grande do Sul (PUC-RS) in Brazil have come to depend on online classes. As in many other institutions around the world, in recent months users have experienced a hybrid context, in which activity has had to be carried out partly remotely, partly in physical environments. This configuration has further increased the demand for network monitoring services, as well as for the entire digital environment responsible for local and remote access.
With the advent of digital technology, companies have been asking customers to trust them in new and deeper ways. But that trust depends crucially on the available technologies being used with transparency, ethical practices, increased data privacy, and strengthened security.Not coincidentally, increasing investments in cybersecurity (74%), information security (64%), and consumer privacy (60%) are the top priorities for business leaders to demonstrate a commitment to building digital trust, according to a recent PwC survey of 311 executives from mid-to-large US companies. More than half of them (53%) strongly agree that innovation can be more effective than regulation in building stakeholder trust. That’s why nearly half (49%) have made significant changes in the last 12 months to the way their companies operate.
Unlike NetFlow, SNMP can be used for real-time network management as well as for monitoring and troubleshooting CPU and memory usage – features that are not currently provided by the NetFlow protocol. NetFlow does consume a lot more disk space than SNMP, but that is mainly because it is much more verbose than SNMP. SNMP has proven itself to be the most reliable network management protocol for routers, switches, and multi-protocol usage. However, because NetFlow provides more information, it is better for deep network analysis and debugging. NetFlow is best used for providing more detailed information about applications and traffic sources. Another advantage of NetFlow is that it uses push technology, which makes it capable of showing information as soon as it is available whereas SNMP uses pull technology to pull data from the device’s MIB (Management Information Base) at specific intervals. NetFlow can also provide information on speed, volume, and link usage.
Monitoring patients wherever they are and supervising their health status relentlessly is a pressing task. Inspired by this need, a group of companies recently presented a smart t-shirt with 5G connection and sensors embedded in the fabric that can capture and send real-time information about the user’s health conditions to care centers.Made of washable material without metal components, the T-shirt has biosensors capable of measuring vital signs, such as body temperature, heartbeat, respiratory rate, muscle effort, and sweat elements. The parameters are recorded in a miniaturized control unit and are converted to digital format, which can be transmitted to the user’s smartphone or smartwatch or to a remote center that will analyze the data using medical software.
