Many variables — such as your users' device type and configuration, external hosting services, and third-party libraries — can impact an application's performance. Without a performance monitoring system in place, numerous problems can arise. These issues could even mean that users stop using your application.
Any application you build has three distinct layers - a server-side interface, a client-side interface and the central codebase. In a monolith application, all these programs are written in a single language, and placed in the same web stack as well. Earlier web applications were written this way.
Coding is a big part of building an application. But, most of the time, you don’t write the entire code. Yes, you don't! Some people, usually big companies, provide pre-written codes for certain standard functions - like loggers, APIs, etc. This is because these functions work the same way in most applications; they require only simple fine-tuning to be adapted for your program as well. In such a case, writing it all from scratch would be a waste. And that is why developers use libraries.
At Canonical, we often get questions about open-source security and of course, Linux security is a common topic. Based on a recent webinar hosted by our security team and an accompanying blog post, we put together the most common questions we receive. This is by no means an exhaustive list, but it should give you a general idea about Ubuntu’s approach to security vulnerability management, livepatch, IoT, and its compliance and hardening tools.
The risk from insider threats has grown massively, with perpetrators frequently getting around organizations' increasingly complex perimeter protections. It is one of the most common ways customer data or industrial and trade secrets leak. This very complex topic includes many types of threats and techniques. Let's discuss how you could detect insider threat activity at a network level.
