| Sumario: | It is our great pleasure to welcome you to the 2021 ACM International Workshop on Security and Privacy Analytics (IWSPA 2021). This year's workshop is the seventh in the series and is co-hosted with the Eleventh ACM Annual Conference on Data and Application Security and Privacy (CODASPY 2021). IWSPA addresses important research topics associated with the application of data analytics tools (including statistical, machine learning, data mining, and natural language processing) to challenges that arise with security and privacy preservation. IWSPA provides a forum for the interaction between researchers in these areas, identifying and pursuing new topics that arise in the intersection between the fields of Artificial Intelligence and Cybersecurity. The IWSPA 2021 call for papers attracted 22 papers from four continents (Africa, Asia, Europe and North America). Each paper considered for presentation was evaluated by three reviewers, who were either committee members or assigned by committee members. The reviews were detailed and examined various aspects of the papers, including correctness and presentation. Five papers were accepted for presentation as full papers (11-page limit) and three were accepted as short papers (7-page limit). We thank the authors, reviewers, and program committee members, whose enthusiastic efforts make the workshop possible, and are critical in its success. We also thank the CODASPY publicity chairs, workshop chair and general chair, as well as the ACM Special Interest Group on Security, Audit and Control (SIGSAC), for supporting IWSPA '21. Special thanks are also due to Rakesh Verma, former IWSPA chair, for his guidance during the entire process of organizing IWSPA '21.
