The commitment of each user in following TIMWETECH Information Security policy can minimize costs and the impacts listed above.
The CSO is responsible for the supervision of ISMS implementation and its policies. All employees or external entities are responsible for complying with policies that are part of TIMWETECH’s ISMS.
The current policy or any related standards and controls, is subject to a review process and continuous improvement to ensure its continuing suitability and effectively mitigate the risks related with IS and, consequently the business, in compliance with the applicable rules and regulations.
