ISO 27001 used as a Framework
I agree with the article in that you really need to understand the business drivers, but I also think that a vast majority of business would be best served using ISO 27001 as their Information Security Management System. This gives the framework for their security program as a whole, from the creation of policies to performing compliance activities. I would not even consider certification, unless there is an overwhelming need. The next decision is whether to use the controls contained within ISO 27001, or take the opportunity to swap out more suitable controls (e.g. NIST, CIS20, ISF, PCI DSS etc.). The good thing about ISO 27001 is that it does give a wide coverage of controls across a security program, such as covering non IT-related area's most other controls don't (e.g. policies, people, physical etc.) However, ISO 27001 can be a bit high level and not detailed enough, even if using ISO 27002. This is where tailoring your controls either by using say NIST SP 800-53 across your enterprise, or specific requirements (e.g. PCI DSS). I personally like to use ISO27001 as the framework and also utilise the non-tech controls contained within. Then I would bring in more specific controls to cover the technical side, cloud specific, privacy, IoT etc. My concern about going straight to NIST is that although they are excellent controls, they are designed for information systems and therefore focus on the IT security side and not really a holistic information security program. Lack resources, time, or just need to get some technical controls in fast? I would go with CIS20 controls as they are very easy to follow and lead you through a three stage maturity process.

CVE-2020-15208
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, when determining the common dimension size of two tensors, TFLite uses a `DCHECK` which is no-op outside of debug compilation modes. Since the function always returns the dimension of the first tensor, malicious attackers can ...
CVE-2020-15209
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, a crafted TFLite model can force a node to have as input a tensor backed by a `nullptr` buffer. This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one....
CVE-2020-15210
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, if a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption. We have patched the issue in d58c96946b and ...
CVE-2020-15211
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices f...
CVE-2020-15212
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger writes outside of bounds of heap allocated buffers by inserting negative elements in the segment ids tensor. Users having access to `segment_ids_data` can alter `output_index` and then write to outside of `outpu...
