Which communication protocol is commonly used for incident response in security operations?

• A. Shared emails and informal messages only.
• B. Clear, concise, and standardized radio or phone communication; use of incident command terminology.
• C. Face-to-face meetings only.
• D. Text messages without structure.

Answer: (B)

During security incidents, effective coordination hinges on clear, fast, and standardized communication. Using radio or phone channels with concise messages and established incident command terminology ensures responders from different teams understand each other immediately, maintains situational awareness, and follows a known chain of command. This structured approach minimizes miscommunication, reduces delays, and supports a unified, efficient response.

Relying on shared emails and informal messages is too slow and fragmented for real-time incident management. Face-to-face meetings alone aren’t practical when responders are dispersed or resources are stretched. Text messages without structure can be vague and miss critical details, leading to confusion.
