To secure the information systems and safeguard the personal and social data, experts engaged in the IT security departments should be increasingly turned out. Many universities have incorporated information security courses at the undergraduate and graduate levels as part of information systems or computer science majors, and some high vocational colleges set the IT security specialty to train the information security operators. However, most graduates are lack of practical operations and they don't have the qualifications to do the job. To train the IT security experts, appropriate methods should be developed. We propose a training mode based on project_based learning team. In the team, students work together in small groups aiming at a project topic, which is pertinent to their real contexts. Through analyzing the quality of the ability improving of each individual in the project team, the professional skills and practical experiences of most students are greatly improved.
