US Homeland Security: Evolving All-Hazards Framework Beyond Terrorism, Distinct from DHS

Homeland security in US national policy denotes efforts to protect against terrorism and all hazards, including natural disasters, via an all-hazards approach encompassing prevention, vulnerability reduction, and damage minimization. It originated post-9/11 with the 2002 Homeland Security Act creating DHS, but extends to 187 federal entities beyond DHS, such as FBI, CIA, and FEMA-integrated functions. Definitions vary without consensus, distinguishing it from military-led homeland defense and civilian executive agency DHS.

Wikipedia Reverts Vandalism to Restore Core Definition of US Homeland Security as All-Hazards National Effort

US homeland security is defined as the national effort to protect against terrorism and other hazards using an all-hazards approach encompassing natural disasters and man-made events. Established post-9/11 via the 2002 Homeland Security Act, it involves DHS coordination of 187 federal entities but extends beyond to agencies like FBI, CIA, and DoD. Lacks practitioner consensus, spanning narrow anti-terrorism views to broad jurisdictional hazard coverage; distinguished from military-led homeland defense.

Wikipedia Reverts Vandalism on Homeland Security Page, Preserving Core Definition of All-Hazards National Security Effort

The Wikipedia diff captures a reversion of nonsensical vandalism on the Homeland Security article, restoring the standard definition as a U.S. national effort for safety against terrorism and other hazards, encompassing an all-hazards approach including natural disasters. Content distinguishes homeland security (civilian-focused, post-9/11 policy via DHS formation in 2003) from homeland defense (military protection) and notes involvement of 187 federal entities. Scope includes emergency response, border control, critical infrastructure protection, and biodefense, with noted definitional debates among narrow (terrorism-only) and broad (all sectors) views.

Wikipedia Minor Edit Refines Homeland Security Definition from "In American" to "An American"

A recent minor edit to the Wikipedia "Homeland security" page corrected line 4 by changing "In American national security policy" to "An American national security policy," fixing a grammatical error while preserving the core definition. Homeland security is defined as the national effort to protect against terrorism and hazards, encompassing an all-hazards approach including natural disasters like Hurricane Katrina and man-made events like the September 11 attacks. The term's meaning lacks consensus, varying from narrow anti-terrorism focus to broad coverage of all jurisdictional hazards, distinct from the DHS agency and military homeland defense.

SAL: Modular Framework for Testing Visual SLAM Robustness Across Adverse Perturbations

SAL transforms clean datasets into adversarial ones via modular perturbations modeling fog, rain, and other conditions, with severity in real-world units like fog visibility in meters. Its extensible interfaces decouple datasets, perturbations, and SLAM algorithms, enabling easy addition of new components. Includes a search to pinpoint failure thresholds and evaluates 7 SLAM systems on 3 datasets under weather, camera, and video perturbations.
