I need the document for latest security standards for IT, also I need a security standards for specific field in IT such as IoT, cloud computing and social media.
It is always worth looking directly at the standardisation bodies themselves. For example, https://standards.ieee.org/search-results.html?q=security will list out the IEEE standards. If you go into their pages you will see what standards are being worked on and which are due for release shortly. You can also filter by topic. The same is true for the ISO set of standards: https://www.iso.org/search.html?q=security. Some of the older standards are being updated and other standards are completely new. For the oldest standards you can see how they are superceeded by the new standard. Another point worth noting is that many standards have security embedded as an integral part. For example the new IEEE P2675 DevOps standard, currently under development does not consider security as separate. Rather it considers security as a key part of all stages in product development.
