In the Cyber Security field a vulnerability is a weakness in your computer which could allow a hacker to break in. The CND Cyber Security Situational Awareness Radar is world renowned and receives around 24,000 hits per hour. This app is a simplified version that reports on new vulnerabilities which are discovered across the Internet by our multinational team of researchers. Each vulnerability is assessed for its severity and if deemed relevant, will be posted on both our The CND Cyber Security Situational Awareness Radar and the CND Radar iOS App. When updated, a notification will be sent out to alert users. New vulnerabilities will have a Threat Indicator and Severity Level, and each 24 hours the existing vulnerabilities drop by one level of severity. After day one, the threat indicator becomes a down arrow, after a maximum of three days the vulnerability is removed, only returning if it becomes actively exploited or if a zero-day is patched. This allows the user to spot new vulnerabilities for the same product as they are often released in clusters, days apart.
