IP SLA Fundamentals. Cisco ISE: TrustSec, what is it and why do I care? As promised, in this entry to our ISE blog series we are going to begin our adventure into Cisco TrustSec, or CTS for short.

Cisco ISE: TrustSec, what is it and why do I care?

When I am approaching a new technology, I find it helpful to not only understand what it is, but also why it exists. So, in this post, we’re going to attempt to cover just that; what is Cisco TrustSec and why do I care? TrustSec, what is it? CTS is a security architecture developed by Cisco comprised of three components. When most of us think about CTS, we think of Security/Scalable Group Tags (SGT’s) and Security/Scalable Group Access Control Lists (SGACL’s). Components of the CTS Architecture: MACSec - Media Access Control Security. UPDATE on 11 Jul 2019: I wrote a fresh article describing how to implement MACSec on Cisco devices in the simplest way possible.

MACSec - Media Access Control Security

I think that one is maybe what most of you are searching for.. get it here Media Access Control Security or MACSec is the Layer 2 hop to hop network traffic protection.

Download next-gen vSRX firewall trial. Getting Started With pfSense Software. Overview The pfSense project is a free network firewall distribution, based on the FreeBSD operating system with a custom kernel and including third party free software packages for additional functionality. pfSense software, with the help of the package system, is able to provide the same functionality or more of common commercial firewalls, without any of the artificial limitations.

It has successfully replaced every big name commercial firewall you can imagine in numerous installations around the world, including Check Point, Cisco PIX, Cisco ASA, Juniper, Sonicwall, Netgear, Watchguard, Astaro, and more. pfSense software includes a web interface for the configuration of all included components. There is no need for any UNIX knowledge, no need to use the command line for anything, and no need to ever manually edit any rule sets. Deployment Selection Hardware Unlike most common commercial firewalls offerings, the pfSense project is just the software portion of the firewall. Cloud.

The software that empowers network professionals. Network Bandwidth - How to Calculate WiFi Bandwidth Need? Bandwidth is the capacity of a channel to transmit data. During the transmission, the information is sent in a binary system, a language that encodes data using only two symbols (often defined as “1” and “0”, or “on” and “off”), each of which is called a bit. The basic unit of this language, the byte, is composed of 8 bits. The bandwidth determines, therefore, the number of bytes that can be transmitted on the connection. The unit of measurement is the bits per second (bps). For example, a low definition video lasting 15 seconds, weighing 1 Megabyte, can be downloaded from an Internet site on your computer in 3-5 minutes if the connection is made via modem (56 kbps) or ISDN line (from 64 to 128 kbps).

Network bandwidth is the capacity of a network communications link to transmit the maximum volume of data from one point to another over a computer network or Internet connection in a given amount of time, usually one second.
