Defining security\r\ncapability levels for the control system component is the goal and objective of this document as opposed to SL-T\r\nor achieved SLs (SL-A), which are out of scope.\r\nThe contents of the corrigendum of August 2022 have been included in this copy.\r\n  CHF 405.-\r\n Share by email\r\nTechnical committee\r\nTC 65 Industrial-process measurement, control and automation\r\nCategory\r\nInformation security and data privacy\r\nPublication type International Standard\r\nPublication date 2019-02-27\r\nEdition 1.0\r\nICS\r\n25.040.40\r\nhttps://webstore.iec.ch/publication/34421\r\nPage 1 of 2\n\n35.030\r\nStability date 2027\r\nISBN number 9782832265970\r\nPages 192\r\nFile size 2.84 MB\r\nSource: https://webstore.iec.ch/publication/34421\r\nhttps://webstore.iec.ch/publication/34421\r\nPage 2 of 2",
