6 Tips for Getting the Most from Your VPN

VPNs are critical for information security. But simply having these cozy security tunnels in the toolkit isn't enough to keep an organization's data safe.

Blanket forts are great. As kids, we love the feelings of warmth and security that come from being wrapped, safe from the world, in that cozy embrace. IT security pros get a similar feeling when network communications are wrapped in a virtual private network (VPN).

VPNs are encrypted "tunnels" through which network traffic can safely flow. But simply having a VPN in the toolkit isn't enough to keep data safe; the VPN has to be deployed properly and used correctly to be effective.

There are two scenarios for deploying a VPN. One is "point-to-point," in which a VPN protects the network links between servers, data centers, or large infrastructure blocks. The other scenario is for mobile, where the VPN wraps the communication from a laptop, desktop, or handheld computer in the blanket fort of encryption wherever the device may be.

In many ways, the VPN between fixed assets is the easier deployment, since it will be totally within the control of the central IT group to connect assets that rarely, if ever, change. However, the mobile VPN "in the wild" is a much different deployment exercise, one that requires particular attention in order for the VPN to be truly effective at protecting the data flowing to and from devices in the field.

What can an organization's security staff do to make sure that its VPNs are protecting all of the data that has to flow from the field? Start with the steps described here, each of which must be communicated with employees so they understand how important data protection is.

One additional point: For purposes of this article, we're discussing VPNs as a general tool — not just the public VPN services widely used by consumers. If you're already using VPNs for all your network connections, let us know what your best practices look like in the comment section, below.

VPN on your router
Legit, I think the best thing you can do is install a VPN on your router. I know from experience that ExpressVPN has their own router apps, I think Nord may also.

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...
