Time Management

One of the things at #WISPAPALOOZA2018 I kept hearing was “I don’t have the time”.  Randy Pauusch gives a talk on time management.  Why pay attention to this video? Randy Pausch was diagnosed with pancreatic cancer and he was working against this when giving this talk.  He only had a limited time to live and became an expert on time management because he had to.

 

NIST releases second draft of “Guidelines for the Selection, Configuration, and Use of Transport Layer Security (TLS) Implementations.”

From an e-mail the folks at nist sent out.

NIST has released a second draft of NIST Special Publication (SP) 800-52 Revision 2,Guidelines for the Selection, Configuration, and Use of Transport Layer Security (TLS) Implementations. It provides guidance for selecting and configuring TLS protocol implementations that utilize NIST-recommended cryptographic algorithms and Federal Information Processing Standards (FIPS). The document requires that government TLS servers and clients support TLS 1.2 configured with FIPS-based cipher suites, and recommends that agencies develop migration plans to support TLS 1.3 by January 1, 2024.

A public comment period for this document is open until November 16, 2018.

Guest Article: Can my router catch a virus?

Our friends over at TechWarn have their take on routers vulnerable to virus attacks

https://www.expressvpn.com/blog/can-my-router-catch-a-virus/

Big price differences between routers are often confusing to consumers as, unlike with personal computers, the quality difference is not always obvious. As routers are normally tied to a physical location, it is also rather difficult to test their reliability in different environments, unlike with highly mobile laptops or smartphones.

Routers often do not receive updates, or updates have to be manually downloaded and applied — a cumbersome process that is not an attractive option to many non-tech-savvy users.

Routers are desirable targets for attackers as they sit at a very sensitive spot on a network — right at the edge. They are a centralized point and connected to every single device in the network. Routers read all of the data that each device sends to the Internet, and if these connections are unencrypted, the router could easily inject malicious scripts and links.

CredSSP error message fix for Windows RDP

The folks over at On-Ramp Indiana found a fix for this one.
The Microsoft Tech Article can be found here…

Symptoms


Consider the following scenario:

In this scenario, you receive the following error message:

If you are getting a CredSSP error message when trying to RDP to a server add this registry key to your local computer.  It will disable CredSSP

Cambium PTP550 Data Rates

Some info on the cambium PTP 550 Data Rates

“Downlink Max Rate” specifies the maximum downlink MCS value that the Rate Adapt algorithm will choose.
MCS values range for data from MCS 9 to MCS 1 for one or two Spatial Streams (Single Stream and Dual Stream respectively). A higher MCS value (e.g. MCS 9) carries more data, but requires more link budget / stronger radio signal. Thus, MCS 9 provides the most data, but the least robust link (i.e. greatest chance data can be lost) and MCS 1 provides the least data, but the most robust link (i.e. least change data can be lost).
DS MCS provide two streams of independent data over the two transmit chains while SS MCS provide one stream of data over both transmit chains.
Setting “Uplink Max Rate” to a DS MCS 9 – DS MCS 1 value will allow this MCS and all lower dual stream MCS values to be used along with all similar or lower single stream MCS values. For example, choosing DS MCS 8 means that DS MCS 8 – DS MCS 1 and SS MCS 8 – SS MCS 1 will be used in the Rate Adapt algorithm. Setting “Uplink Max Rate” to an SS MCS 7 – SS MCS 1 value will allow this and all lower single stream MCS values.
