The Standard for Telecommunications Organisations
What is ISO 27011?
The international standard ISO/IEC 27011 is part of the ISO 27000 series of standards. In 2008 it was published by Joint Technical Committee JTC1 established by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Its official title is "Information technology — Security techniques — Information security management guidelines for telecommunications organizations based on ISO/IEC 27002".
ISO 27011 is to be regarded as an industry-specify ISO 27001 supplement, covering specific security requirements for telecommunications providers. Accordingly, organisations can only be certified against ISO 27001. The implementation guide for both standards is ISO 27002. With ISO 27011, providers have gained the opportunity to establish a required minimum of information security in order to ensure the confidentiality, availability, and integrity of the data processed.
Telecommunication-Specific Threats and Vulnerabilities
Every day, telecommunication companies process large amounts of data from a variety of users. This includes highly sensitive information such as authentication or business data requiring high levels of security.
Another aspect to consider is the high risk this industry is exposed to: the likelihood of security incidents such as hacker attacks is significantly larger than in other sectors, and often consequences are more serious: the strong interconnection of systems often causes incidents to affect large parts of the network. Resulting downtimes do not only involve financial losses, but may also damage a provider's reputation.
