How to use managed IT services like the Fortune 500

Managed IT services are widely used by the most sophisticated organisations across the globe. Recent reports show that over 90% of the Fortune 500 have multiple outsourcing contracts to managed service providers, with a value of over $190 billion. This includes managed IT services such cloud services, infrastructure, networks, security, backup, applications and much more. How can organisations at any scale adopt the same strategy and benefit from managed IT services?

Basic DHCP concepts

Let’s step back and take a very basic look at DHCP. In fact, let’s look at the analogy of assigning a street address to your house. Usually, this is done by the local 911 dispatch office, or some other central authority. They typically use either a survey map or a latitude, longitude pair to locate you, before they assign your house numbers from a pool of available addresses, compatible with other addresses in the area.

Two-factor authentication coming to Ubuntu One

Two factor authentication (2FA) increases your account security further than just using a username and password. In addition to a password (the first factor), you need another factor to access your account. A great example to demonstrate this is when you withdraw money from an ATM. To access your bank account you need both your physical bank card and to know your PIN number. These are the two factors you need to withdraw money = 2 factor authentication!

How to manage a 24×7 private cloud with one engineer

In the last several years, we have witnessed the creation of many technologies, starting with the cloud and going further to machine learning, artificial intelligence, IoT, big data, robotics, automation and much more. The more the tech evolves, the more organizations thrive to adopt these technologies seeking digital transformation and disrupting industries along their journey, all for the benefit of better serving their consumers.

Beyond the network: Next Generation Security and Observability with eBPF - Shaun Crampton, Tigera

Learn how eBPF will bring a richer picture of what's going on in your cluster, without changing your applications. With eBPF we can safely collect information from deep within your applications, wherever they interact with the kernel. For example, collecting detailed socket statistics to root-cause network issues, or pinpointing the precise binary inside a container that made a particular request for your audit trail. This allows for insights into the behavior (and security) of the system that previously would have needed every process to be (manually) instrumented.

CVE-2021-31440: Kubernetes container escape using eBPF

In a recent post by ZDI, researchers found an out-of-bounds access flaw (CVE-2021-31440) in the Linux kernel’s (5.11.15) implementation of the eBPF code verifier: an incorrect register bounds calculation occurs while checking unsigned 32-bit instructions in an eBPF program. The flaw can be leveraged to escalate privileges and execute arbitrary code in the context of the kernel.
