Directory
Cybersecurity
Cybersecurity is the practitioner side of the directory, aimed at people who defend systems or investigate them. Security tools and toolkits covers scanners, frameworks, and command line utilities. Security scanners and resolvers follows with services that check a host, a certificate, or a configuration. Domain, IP, and DNS research collects lookup and reputation tools, while malware protection lists engines, sandboxes, and analysis services. Safety and risk research covers threat reports, vulnerability databases, and standards, and IoT security deals with connected devices and their firmware. Threat intelligence, malware analysis, password and hash tools, and sandboxes and emulation sit at the deeper end of the category. Check what a tool is built to do and whether you are allowed to point it at a target before you start a scan.
