The cybersecurity state of affairs can be described as too complex today. There is an enormous number of threats endangering sensitive data for the average IT team to cope with. Threats ranging from exposure of physical assets stored in an office, to “social engineering” attacks resulting in unauthorized access, or even threats that exploit obscure software vulnerabilities.
Many people are familiar with the stories of coal miners using canaries to detect carbon monoxide and other toxic gases as a warning system for when they should evacuate. Even though cybersecurity is far removed from coal mining, it has an equivalent “canary in the coal mine” that takes the form of indicators of compromise, or IoC for short. So why should an MSP be concerned with looking for IoCs?
It has been a while since I have been excited to write about encrypted tunnels. It might be the sheer pain of troubleshooting old technologies, or countless hours of falling down the rabbit hole of a project’s source code, that always motivated me to pursue a better alternative (without much luck). However, I believe luck is finally on my side.
The identification of every user making a request to a given system is vital to ensuring that action is only taken by, and information only returned to, those who need it. This happens in two steps: first, the requester is identified (authenticated), and then that identity is used to determine which parts of the application they are allowed to access.
In the workplace, certain web pages can be a distraction for employee productivity—or worse, a disruption. If you’re a managed services provider (MSP), your customers may be interested in finding a way to control the types of websites their employees can access during the workday. One viable option for them to utilize is a DNS block to restrict access to certain web addresses on a given server. This article will help you understand what DNS block is, who uses it, and how it works.
If you haven’t had a chance to check out VMware Tanzu Mission Control, you’re missing out on one of the greatest tools available to manage Kubernetes. However, it’s not just for managing one cluster; rather, it delivers “fleet-wide” management with a focus on policy. Policy management is powerful because it enables us to, for example, limit access to certain users or prohibit pulls from specific container registries.
When you think about how to automate processes within the IT industry, your mind probably goes first to tools. After all, the past decade has witnessed an explosion of tools from across the industry that promise to make it easy to automate virtually every aspect of IT operations — from low-code development solutions that automate coding, to release automation tools for applications, to automated monitoring and security platforms.
Extended Berkeley Packet Filter (eBPF) is a relatively new feature for Linux kernels that has many DevOps, SREs, and engineers excited. But is it a one-stop shop solution for all of your Linux kernel needs? Let’s take a look at what eBPF does well, and how it stacks up against standard Linux iptables.
The Internet is a tool that, without a doubt, offers a great amount of positive aspects in the daily life of our society, like instant communication, easy access to information… among many other benefits. But also it has negative aspects, and one of the big ones is cyberattacks. That is why we give you today 21 computer security tips for beginners!
