The Opera company conducted research showing that […]
Ignoring reports about issues requesting the ability to use GitLab without providing access to JavaScript, GitLab continues to tighten its reliance on JavaScript. The server no longer returns the file list as HTML but instead adds an element with the id 'js-tree-list' to the page, with items inserted via JavaScript.

But when […]

Qualys has discovered yet another critical remote vulnerability (CVE-2020-8794) in the OpenSMTPD mail server developed by the OpenBSD project. Just like the vulnerability identified at the end of January, the new issue allows remote execution of arbitrary shell commands on the server with root user privileges.

Ethernet is everywhere, and tens of thousands of manufacturers produce equipment that supports it. However, almost all of these devices share one common number – MTU: $ ip l 1: lo: mtu 65536 state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: enp5s0: mtu 1500 state UP link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff MTU (Maximum Transmission Unit) [maximum transmission unit] […]
With this post, I want to open a series of articles dedicated to IdentityServer4. We'll start with the basic concepts. The most promising authentication protocol at the moment is OpenID Connect, and the authorization protocol (granting access) is OAuth 2.0. IdentityServer4 implements these two protocols. It is optimized to address typical security issues. OpenID Connect is an authentication protocol and standard; it does not provide […]
