Low-tech security culture
To speak of training and security culture, it really touches all levels of the organization -- and information security should be top of mind even in low-tech contexts.  (After all, social engineering is the skilled hacker's top choice when it comes to finding weaknesses.  All it takes is a slip-up during a phone call.)

White List Thinking
We need a "Sea Change" to Whitelist Thinking.

it is necessary to authenticate many messages, certainly those dealing with money, -- or software.

The Essential Element to this change in thinking deals with the symmetric nature of our customary identification data.   Name, address, date of birth, Social Security Number -- even Company Letterhead Stationary -- can all be easily compromised in the digital world.   These keys -- once released in public -- are compromised forever.   In this they act like the symmetric keys used on basic encryption where the decryption key is the same as the encryption key: a shared secret.

The trouble is our traditional identification data are a shared secred -- with everyone in on it.   See KREBS essay on "Superget" -- a DarkWeb service selling these symmetric keys

this is why we need to move to the general use of PGP

PGP is based on asymmetric keys: the signing key is private and the authentication key is public.   This means you can produce an authenticated document in public -- without compromising your identity -- i.e. your private key

many detractors claim this is too complicated for ordinary people.  This is a myth that needs to be dispeled. As packaged technology it is no more difficult to use PGP than it is to use the PIN on a debit card to get cash from an ATM.   Practice using the ENIGMAIL plug-in for the Thunderbird eMail client.

There are two keys to progress in fighting hacking

1. use a secure operating system.   A secure operating system is one which will not allow itself to be compromised by the activity of an application program -- such as a web page.

2. authenticate transactions -- including software downloads, eMail, tax forms &c -- using PGP

Half-way measures have been ineffective.   It's time to recognize hacking as a problem that must be addressed in a serious manner.

well done.
Thanks for a well considered and well written post.

 

As always we want easy. We don't want maintenance. We want things to work so we don't have to. So we buy cars with low maintenance and trade them out on a lease, our phones are disposable when the 32 year contract is up, and we expect internet security should work out of the box.

Jeff, it is just the way it is. Our entire modern culture is avoidance and avoiding responsibility.

Good article - excellent points, but it isn't about to change. We will continue to drive and talk on our cell phones and we will continue to ignore best practices in security and when there is a breach we will point fingers.


Thanks again. good post.

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...
