NSIA is an application for detecting defacements, errors, information leaks and other types of security problems on websites and web applications (think of it as a "website IDS").
The main dashboard clearly displays the status of the scanner and of the monitored websites.
Scan reports indicate what resources were discovered and provides details on what issues were observed.
ThreatScript signatures perform deep content analysis and can detect significant changes.
ThreatPattern signatures can identify known-bad elements such as attacks, offensive language and information leaks.
The rule status page shows indicates the current state of each rule; including which have found issues, were unable to scan (for example, due to an outage in the webserver) or those rules that have not been scanned yet.
The rule history page displays the status of past scans.
NSIA was designed for multiple users and supports sophisticated access controls.
The system status page displays the operational status of the scanner, including memory usage, number of threads, number of rules evaluated, etc.
Individual scan policies can be defined in order to tailor the scans according to the websites begin scanned.
NSIA features a built-in database (no DBA required). NSIA maintains the database by creating backups, defragmenting indexes, etc. You can also use an external database instead.
