With a view to stimulating cooperation between the public and private sector and within the private sector, in particular to support the protection of the critical infrastructures, ENISA should support information sharing within and among sectors, in particular the sectors listed in Annex II to Directive (EU) 2016/1148, by providing best practices and guidance on available tools and on procedure, as well as by providing guidance on how to address regulatory issues related to information sharing, for example through facilitating the establishment of sectoral information sharing and analysis centres.
