Getting management to back your application security plans can be a tough sell. Metrics are vital because they help you understand how effective your initial cybersecurity measures are and how to turn them into measurable data that's easy for everyone to understand. This article will explore how to use metrics to get the support you need and make your application security programs more effective.

Zero-days are out there. Lurking just under the surface, waiting for the right moment to strike. A security team can do everything right and still experience a zero-day attack in its supply chain.

When we first built the CISA KEV enrichment dashboard at Nucleus, our goal was to gain new insights into the vulnerabilities that had been confirmed by CISA as being exploited. Recently, CISA expanded the Known Exploited Vulnerabilities Catalog with vulnerabilities “known to be used in ransomware campaigns”. We find this data valuable in helping organizations identify which vulnerabilities on the KEV pose greater risk.

A cross-site request forgery attack (CSRF) attack is a security vulnerability capitalizing on trust between a web browser and a legitimate website. Crafty attackers manipulate browsers into executing malicious actions on websites where users authenticate themselves and log in. Often, these attacks start when users click a link attached to a deceptive email or land on a compromised website, unaware of the logic executing in the background.
