I. Core Characteristics of Security Information

Highly purposeful: The ultimate goal of all safety information is to "avoid risks" or "reduce harm", rather than merely convey knowledge or entertainment. For instance, the core purpose of the instructions on a fire extinguisher is to guide people on how to put out a fire correctly during a fire, rather than to introduce the product's principle.

Strict timeliness: Most security information has "immediate validity". Outdated security information may lose its value and even cause danger. For instance, earthquake early warning information needs to be transmitted within a few seconds to tens of seconds before an earthquake; otherwise, it is meaningless. The "shelf life" of food is essentially also safety information. Once it exceeds the expiration date, its warning function becomes ineffective.

High accuracy requirements: Deviations or errors in safety information may directly lead to accidents. For instance, if the "toxic substance leakage concentration data" of a chemical enterprise is wrongly reported, it may lead to insufficient emergency measures (failure to evacuate in time) or excessive measures (triggering panic). If the speed limit signs on the road are marked incorrectly, it may cause traffic accidents.

Scene dependence: The content and form of security information will change with the application scenarios and need to match the specific types of risks. For instance, "gas leakage alarm" in household scenarios, "mechanical operation procedures" in factory scenarios, and "fire evacuation route map" in public scenarios, although all are safety information, the risks they target and the objects they convey are completely different.

Ii. Main Classifications of Security Information (by Application Scenarios)

The coverage of security information is extremely wide. According to the service scenarios, it can be divided into the following categories, almost covering all areas where "risks need to be prevented"

Personal and family safety category: The core is to safeguard an individual's life, property and daily safety, and guide individuals to avoid common risks in life. For instance, the "leakage alarm sound" of a gas alarm, the "anti-electric shock warning" in the user manual of household appliances, and the "anti-picking status feedback" of a door lock.

Production and industrial safety category: Mainly used to prevent production accidents (such as mechanical injuries, chemical leaks, explosions), ensuring employee safety and production stability. For instance, the "Fault shutdown warning signal" for factory equipment, the "toxic gas concentration display screen" in chemical workshops, and the "Safety Regulations for High-altitude Operations" in construction projects.

Public safety category: Focuses on preventing group risks in the public domain (such as disasters, accidents, and public health incidents), and guides the public's emergency response. For instance, "meteorological disaster warning text messages" for earthquakes and heavy rain, "fire evacuation signs" in subway stations, and "protection guidelines" during the epidemic.

Information and network Security category: It is used to protect data and systems from attacks, leaks or damage, and ensure the security of the digital environment. For instance, the "Unfamiliar Device Login Reminder" on mobile phones, the "Hacker Attack Defense Log" on enterprise systems, and the "Vulnerability Repair Patch Prompt" on software.

Traffic and travel safety category: The core is to prevent traffic accidents, regulate the behavior of traffic participants, and convey the road/traffic conditions. For instance, the "Speed limit/No Overtaking signs" on roads, the "Traffic jam warning Ahead" on navigation apps, and the "Safety Instructions before Takeoff" on aircraft.

Environmental and ecological security category: It is used to monitor environmental pollution and ecological damage risks, and guide environmental governance and risk avoidance. For instance, the "Water pollution index report" of rivers, the "heavy metal content detection data" of soil, and the "radiation dose monitoring results" of nuclear power plants.
