Risk-based alerting slashes SOC noise -- when done right | TechTarget
When the Cybersecurity and Infrastructure Security Agency (CISA) recently announced it would end its 22-year-old weekly vulnerability bulletin, the move marked a federal acknowledgment that the sheer volume of security alerts has made static severity scores nearly useless for prioritization.
CISA's pivot toward risk-based prioritization reflects an industry-wide reckoning with an overwhelming avalanche of threat telemetry. But while the policy direction is clear, the path to practical implementation has remained murky for many security operations centers (SOCs).
