Controlled Unclassified Information, or CUI, must be protected at the moderate confidentiality level defined by NIST SP 800-171. That standard is built on the moderate control baseline from NIST SP 800-53, and it applies to every nonfederal system, network, and organization that stores, processes, or transmits CUI. It sits wellContinue Reading
Zigbee and Thread are the two most common low power wireless protocols behind smart home devices like bulbs, sensors, locks, and thermostats. Both build a mesh network so devices can relay signals to each other instead of relying on a single router. The real difference comes down to what sitsContinue Reading
Most models people call “open source” today are not actually open source. Llama, DeepSeek, Qwen, and Gemma all get labeled that way in headlines, but under the definition the software industry actually uses, almost all of them are open weight instead. The difference sounds technical, but it decides whether youContinue Reading
Crosstalk happens when a signal on one wire pair leaks into a neighboring pair and shows up as noise. Near End Crosstalk (NEXT) is measured at the same end of the cable where the signal starts. Far End Crosstalk (FEXT) is measured at the opposite end, after the signal hasContinue Reading
GROW with SAP and RISE with SAP are the two paths SAP offers for moving a business onto S/4HANA Cloud, and the choice between them comes down mostly to where a company is starting from. GROW is built for organizations that are new to SAP and want a standardized, publicContinue Reading
The biggest difference between Cat6a and Cat6e is that only Cat6a is an official cable standard. Cat6a (Category 6 Augmented) is defined by the Telecommunications Industry Association under TIA/EIA 568.2 D, tested to a guaranteed 500 MHz bandwidth, and certified to run 10 Gbps over the full 100 meter channel.Continue Reading
LPWAN is a broad category of wireless technology built for sending small amounts of data across long distances on very little battery power. LoRaWAN is one specific, open standard protocol that lives inside that category, alongside options like Sigfox, NB IoT, and LTE M. It happens to be the mostContinue Reading
Onion over VPN sends your traffic through a VPN server and then through three volunteer run Tor nodes, while Double VPN sends it through two servers owned by the same provider. Onion Over VPN wins on raw anonymity because the routing is decentralized and no single company can see theContinue Reading
Cat 4, Cat 5, and Cat 6 are three generations of twisted pair Ethernet cable, and they are not close cousins. Cat 4 tops out at 16 Mbps and is obsolete. Cat 5 supports up to 100 Mbps. Cat 6 handles up to 10 Gbps over shorter runs. If youContinue Reading
LTE-M and NB-IoT are both cellular technologies built for the Internet of Things (IoT). They run on licensed mobile spectrum, which means they use the same towers and infrastructure as regular 4G and 5G networks rather than needing new hardware installed nearby. LTE-M stands for Long Term Evolution for Machines.Continue Reading
