The IB ACIO profile primarily involves intelligence collection, surveillance, security analysis, and operational support. Officers monitor sensitive information, investigate suspicious activities, assist senior officers in national security matters, and coordinate with other intelligence or law enforcement agencies. The role requires discretion, vigilance, strong observation skills, and commitment to duty. Postings may include field intelligence gathering, office analysis work, or both. While the job can be demanding and at times stressful due to its secretive and strategic nature.
