In today’s complex network infrastructure comprised of diverse resources, devices, and users, port scans represent a significant amount of network traffic. Crackers and hackers alike use port scanners to discover port vulnerabilities that can become attack vectors to malicious outcomes. In this post, we discuss the fundamentals of port scanning, and why you need to deploy an effective port scanner software on your network right now.
Async hooks are one of those Node.js features that seem interesting when you first see them, but in practice they end up failing to provide overtly obvious use cases. At their core, async hooks are a way to step into the lifecycle of any asynchronous resource. This may be a promise, a timeout, streams, DNS lookups, and even HTTP requests—like API calls. Most examples are focused on tracking the execution context or enhancing asynchronous stack traces.
Network security management typically entails end-to-end management of the entire network security infrastructure of an enterprise. However, in this rapidly changing security ecosystem, there’s an inherent need for IT admins to be extremely agile to maintain an effective security posture.
Halloween is tomorrow, and do you know what that means? For starters, it means you can dance under the rare blue moon. A full moon visible for all time zones on Earth hasn’t happened since 1944, and won’t happen again until 2039. It also means you can don a costume and be anything you like. Kind of like a fraudster, that assumes a new persona every time there is a payment fraud attack.
In our previous article we talked about Synthetic Monitoring—a technique used to automate the testing and monitoring of resources by performing simulated user interactions and API calls. Now we're going to look at a complimentary technique called real-user monitoring which takes a more passive hands-off approach.
Testing uptime, response time, and other performance metrics in applications can take a few different shapes. One common technique is an approach known as synthetic monitoring. This form of performance monitoring doesn't rely on real users interacting with a service, and instead uses automated tools to mimic interactions. Then, the results are recorded and parsed just like other solutions.
Most of us can think of a time when we received a phishing email. In fact, most phishing emails are easy to identify, and automatically go to spam. However, in this ongoing pandemic, hackers are adopting advanced tactics that cleverly conceal their malicious intentions, and fly under the radar by leveraging the victim’s fear, anxiety, or plain negligence.
