Distributed denial of service (DDoS) is a broad class of cyberattack that disrupts online services and resources by overwhelming them with traffic. This renders the targeted online service unusable for the duration of the DDoS attack. The hallmark of DDoS attacks is the distributed nature of the malicious traffic, which typically originates from a botnet—a criminally-controlled network of compromised machines spread around the globe.

This blog was written by a third party author Zero Trust is a cybersecurity model with a tenet that any endpoint connecting to a network should not be trusted by default. With Zero Trust, everything and everyone— including users, devices, endpoints —must be properly verified before access to the network is allowed.

As companies shift more focus to combatting the recent epidemic in ransomware attacks, they are faced with choices on how to best deploy defenses to counter new attacker tactics and stay ahead of the threat.

A misconfiguration is exactly what it sounds like; something that is wrongly configured. From a security perspective this can be either fairly harmless, or in the worst case devastating. We have written about misconfigurations before, both here and here. Misconfigurations may derive from many different reasons, such as: Hackers often exploit misconfigurations, since this can have a huge security impact.

This is a major Teleport release with a focus on new features, functionality, and bug fixes. It’s a substantial release and users can review 4.3 closed issues on Github for details of all items. We would love your feedback - please pick a time slot for a remote UX feedback session if you’re interested. Teleport 4.3 includes a completely redesigned Web UI.

I’ve worked in the IT field for over 30 years. 20 of those years have been spent in the network security field, employed by some of the largest names in the industry. But to my family, I’m still just the guy who “works with computers”. Many of my family are not computer savvy, which is a nice way of saying I had to teach them where the power button is. However, “Power Button Locator” is just one of my jobs. Windows won’t boot up?

When it comes to card-not-present transactions, security is constantly a moving target. Between February and April, the peak period when COVID-19 was spreading across much of the US, cyber-attacks against the financial sector were reported to have risen by 238%. The exponential growth of digital payment transactions, combined with the increasing variety of customer-facing devices and payment applications, has many financial institutions re-evaluating their approaches to cybersecurity.

Software development and delivery is an ever-changing landscape. Writing software was once an art form all its own, where you could write and deploy machine code with singleness of purpose and no concern for things like connecting to other computers. But as the world and the variety of systems that software supports became more complex, so did the ecosystem supporting software development.

In Part 1 of this blog series, we took a look at how we could use Elastic Stack machine learning to train a supervised classification model to detect malicious domains. In this second part, we will see how we can use the model we trained to enrich network data with classifications at ingest time. This will be useful for anyone who wants to detect potential DGA activity in their packetbeat data.
