DKCISSP REPORT

The model is available with zero data retention and through Amazon Web Services, Google Cloud and Microsoft Azure.

A flaw in Titan, an internal Microsoft analytics service, could have let an attacker read employee records and Bing search analytics, a 16-year-old security researcher has disclosed.

Sift is a free, open-source command line tool that searches for passwords, API keys, and other sensitive data across the places a company keeps its work: local disks, Windows file shares, an entire Active Directory domain, SharePoint, OneDrive, Teams channel files, Slack messages, and Jira and Confluence.

Anthropic has released Claude Sonnet 5.5, an AI model for coding and office work.

Users who run Sonnet with thinking turned off must switch to the new between_tools setting before moving to Sonnet 5.5.

Permify is an open-source authorization service that answers access questions at run time: can user X view document Y, which posts can members of team Y edit.

Developers can select it on the Claude Platform using the model name claude-sonnet-5-5 .

As an Application Security Researcher, you will test web applications and APIs to verify vulnerabilities found by Novee’s AI platform and document how they can be exploited.

The company says it responds more than 30% faster than its predecessor and uses fewer tokens to complete many tasks, reducing the cost per task without changing its listed API price.

Faav reported the vulnerability to the Microsoft Security Response Center (MSRC) on September 5.
