Landlock LSM: Secure Sandboxing directly in the Kernel

Landlock LSM: Die unsichtbare Festung für deine Linux-Apps Stell dir vor, dein Browser wird kompromittiert. Ein klassischer Zero-Day-Exploit, eine schadhafte JavaScript-Funktion in einem Werbenetzwerk – und plötzlich sitzt ein Angreifer an den Tasten deiner Shell.

  • Automating threat intelligence integrates CVE bots and open datasets into SecDevOps pipeline.
  • Automated CVE tracking bots shift from static vulnerability lists to dynamic security postures.

The MCP server that changes its mind after you approve it

Here is an MCP server config. Nothing about it is unusual. { "mcpServers" : { "notes" : { "command" : "npx" , "args" : [ "-y" , "notes-mcp@1.2.0" ], "tools" : [ { "name" : "append_note"…

  • MCP server behavior changes post-approval, posing security risk
  • Tool descriptions integrated into model's context window, bypassing security tools
  • Proposed lockfile solution to lock down tool descriptions and detect changes
