Information Security consists in protecting information and its supporting assets (systems, networks, infrastructures and other) in three essential aspects: Confidentiality, Integrity and Availability. The protection of information must comply with our company's internal policies regarding information but also with all the applicable national and international laws and regulations. It should also consider the service requirements documented in the SLAs, contracts or operating agreements with customers.
NOS’ Security Policy establishes the principles of Information Security to be observed by NOS' Employees, Suppliers and Partners. It also defines the different security levels and domains and their respective control objectives. This Policy is voluntarily based on the adaptation of recommended international standards, such as ISO 27001 and the Technical Guidelines for Security Measures of ENISA - European Network and Information Security Agency.
Please refer to our General Policy for Information Security.
