Researchers have developed a new defense framework called SPARD to combat harmful fine-tuning attacks on large language models. These attacks aim to remove safety alignments and induce unsafe behaviors. SPARD integrates Safety-Projected Alternating optimization with Relevance-Diversity aware data selection, using a method called SPAG that alternates between utility updates and explicit safety projections with safe data. Experiments show SPARD significantly outperforms existing defense methods in preventing attacks while maintaining task accuracy. AI
