A Dynamic Multipoint Virtual Private Network (DMVPN) can be used with other networks like Multiprotocol Label Switching (MPLS), but streaming multicast is accomplished quite well using "Default" and "Data" Multicast Distribution Trees (MDTs) with MPLS.

The first big push toward implementation of IPv6 was mobile devices. Now, one of the driving forces is the Internet of Things. As the name implies, this means everything, including machine to machine communication (M2M).

Switches play a vital role in moving data from one device to another. Specifically, switches greatly improve network performance, compared to hubs, by providing dedicated bandwidth to each end device, supporting full-duplex connectivity, utilizing the MAC address table to make forwarding decisions, and utilizing ASICs and CAM tables to increase the rate at which frames can be processed.

The network forensics market is set to dramatically expand as increasing numbers of organizations become the victims of malware attacks.

Discover why healthcare organizations must take an immediate active role in securing their data. It is much more costly, monetarily as well as with regard to reputation, for an organization to react to a breach rather than plan for it.

Experts agree that as long as there is data, there will be people trying to steal it. For every defense mechanism put in place, there is someone who will find a way to get around it. Constant vigilance, education of the workforce, and management support are all necessary to implement effective security policies. While a well-trained IT staff is key to protecting data, all employees must understand the importance of protecting company assets, including data.

Technology is a wonderful thing, but it comes with a price: cybersecurity.

Consider how many financial transactions are performed on the Internet everyday. Protecting all this data is of upmost importance. Cryptography can be defined as the process of concealing the contents of a message from all except those who know the key. Cryptography can be used for many purposes, but there are two types of cryptographic algorithms you need to understand, symmetric and asymmetric. Symmetric uses a single key, whereas asymmetric uses two keys. What else is required to have a good understanding of cryptography? It’s important to start with an understanding of how cryptography relates to the basic foundations of security: authentication, integrity, confidentiality, and non-repudiation.

Google takes security to a whole new level thanks to their years of experience as one of the most popular targets on the internet for would-be hackers and denial of service bots. This led Google to build a sophisticated security infrastructure the likes of which few companies or organizations can claim. Google approaches security holistically and involves everything from the physical data centers, to the data pipelines between them, down to the training of each employee that is responsible for managing the infrastructure.

In the digital age, people and intellectual property have supplanted physical assets as the most important criteria for determining the value of an organization.

There are several advantages to implementing a route-based VPN (a.k.a. tunnel interface VPN) instead of a site-to-site one. Learn more.

While Apple has created many fine things, they were yet to be created themselves when Xerox PARC scientists created Media Access Control addresses. These MAC addresses are 48 bits or 6 bytes long, so they are also known as MAC-48 or EUI-48. EUI stands for Extended Unique Identifier. It is written in hexadecimal characters as shown below:

The key difference between hubs, switches and bridges is that hubs operate at Layer 1 of the OSI model, while bridges and switches work with MAC addresses at Layer 2 of the OSI model.
