Suspicious Link	suspicious-link-v2	Suspicious resources, based on blacklists monitored by Nimbusec, are embedded (but not loaded) on a Web page. A typical example of this type of event would be a link (a-tag) which points to a suspicious domain found in the Nimbusec blacklist.
Suspicious Request	suspicious-request	A suspicious resource, based on blacklists monitored by Nimbusec, is actively loaded by a Web page. A typical example of this type of event would be a JavaScript source which points to a suspicions domain.

Configuration

opendir	config-opendir	When a web server’s directory listing is enabled, anyone can browse the contents of folders (e.g., `/files/`) instead of being restricted to specific pages.
php Error	config-phperror	When PHP error messages are shown directly to users instead of being logged securely.
public config	config-public	Apache status pages are checked for public accesibillity.
Security Header config	config-secheads	Will be shown if SHR rating is grade "D" or lower. (missing or improperly configured HTTP security headers, such as Content-Security-Policy, Stricy-Transport-Security or X-Frame-Options)
Deprecated Header	config-header-deprecated	The server uses outdated headers that are no longer recommended. They should be replaced with modern alternatives for better security and compatibility.

Text

SRI Missing	sri-missing	No integrity hash is defined for the external resource.
SRI Invalid	sri-invalid	The provided hash does not match the actual content of the loaded file.
Hijack Link	hijack-link	The destination domain of the link is not (or no longer) registered. Attackers can register this address to redirect users to malicious or phishing content.
