Evolved Firewalls

Similar to every technology, firewalls have also changed over the past few decades.

A firewall is a security device for the network that monitors both incoming and outgoing traffic over a network and allows or blocks the network traffic according to its programmed security rules. For a quarter of a century, these firewalls have served as the first line of defense in network security. Firewalls create a barrier between secured and controlled in-house networks. They also decide whether to trust an external system or not, such as the Internet.

In modern-day firewalls, you get to see more than just a packet inspection. Because of their proven ability to block malicious traffic from accessing the corporate networks and guard the most valuable assets of organizations, firewalls have become ubiquitous throughout their IT landscapes.

How Have Firewalls Evolved Over the Years?

Firewalls were invented as a software tool to regulate access from mainly free and non-targeted network security threats. Over the years, firewalls have evolved into exclusive hardware devices. As the appliances, firewalls are enforced to adjust according to the continually rising performance demands. With the increasingly sophisticated attacks, firewalls are also required to embrace additional security functionality. With the introduction of the public and private cloud services, a division of firewalls needed to get back to their software state and virtualized form.

The contribution of a firewall towards a cyber-ecosystem has been refined with evolution. Having progressed from a simple access guard, a few forms of modern firewalls act as a highly sophisticated cyber defense system. The evolved firewalls have taken on the extremely challenging, tough, and sneaky adversaries. Next-Generation Firewall (NGFW) solutions and the multi-solution Unified Threat Management (UTM) are the two examples of evolved firewalls.

The Latest Trends in Firewall Security

Modern-day firewalls, also known as next-generation firewalls at present depend more on a similar analysis of the application layer. However, evolved firewalls are more focused on deep-packet introspection. To this extent, evolved firewalls can be highly effective in the execution of different security features such as detecting and preventing intrusions, integration of user ID, firewalls for Web applications. Another latest trend in Firewall security is the integration of Virtual Private Network (VPN) services into firewalls. This has become a common practice by most enterprises because it enables off-site employees of an organization access company resources while interacting over an unprotected network such as a public Wi-Fi.

Guest Post: Smart Card Technology

Massive Networks uses various types of smart cards for security measures within its data center facilities. And because the smart card is among the digital icons in today’s information era, we thought’s we’d share a feature guest post about it from our friends at The Smart Card Institute.

Smart Card Technology – Types, Applications, and Working

Your smart card is always at your beck and call for making transactions every now and then. Today’s article takes a dive deep into the types, applications, and workings of this technology.

Smart card technology is available in markets for gaining access to products and services, for authenticating identity, and for establishing and facilitating trade. In a survey conducted in 2016, it was discovered that 27 percent of smart card applications are utilized in the banking industry, 18 percent in the welfare and health sectors, and 15 percent in the transportation industry. Besides these, smart card tech equally applies to other applications, including radio security, identification, telecommunications, and metering. In this article, we elucidate on the types of this technology, its applications, and how it works.

What is a Smart Card?

“Smart card” is a term used to describe a special kind of card-like device, pocket-sized, and containing a small integrated circuit (IC) chip. Also called a readable device, it is deployed for security verification in big corporations. The IC chip embedded in smart cards could be a simple memory circuit or a microprocessor with memory. These cards have 3 primary functions: storing personal information/data, authentication, and storing values.

Types of Smart Cards

Contact Smart Card

This type comprises electrical contacts that connect to the reader where the smart card gets inserted. In a contact smart card, the electrical contacts can be seen arranged upon a conductive gold plated coating on the surface.

Contactless Smart Card

The contactless type establishes communication with your card reader without any form of physical contact. Contact-less smart cards consist of an antenna, used for communicating with the RF (radio frequency) band with the antenna on the reader. This antenna gets power from the reader via the electromagnetic (EM) signal.

Furthermore, based on smart card functionalities and configuration, 2 types of cards can be identified:

Memory Cards

These comprise only memory circuits and are used for storing, reading, and writing data to a specific location. These are cards which only consist of memory circuits. The data, stored and written in this manner, can neither be manipulated nor processed.

A memory card is also used as a rechargeable or disposable card, containing memory units usable only once. This type is a straight memory card, which is only used for storing and writing data. And this data is protected from unrestricted access.

Microprocessor-Based Cards

Microprocessor-based cards consist of a microprocessor, which is inserted into the chip together with memory blocks. This type has specific sections of files, associated with a specific function. The data contained in these files are either managed by a fixed operating system or a dynamic one. Microprocessor-based cards also carry out multiple functions and are equally utilized for data processing as well as manipulations.

How Smart Cards Work

Your smart card is connected to the controller or host computer through a card reader — also known as an interface device, card programmers, or a card acceptance device — that receives information from the card and then conveys this information to the controller or host computer. A difference of one minute exists between both the reader and the terminal.

When your smart card gets closer to a smart card reader, the card identifies itself to the interface device by transmitting information and receiving it. If the data that is exchanged does not match, any further processing will cease. Smart cards, just like ordinary bank cards, can secure themselves against unauthorized use.

Applications of Smart Cards

Smart cards were first introduced 3 decades ago in Europe as a storage value tool for payphones to crack down on perpetrators of theft cases. Since that time, the smart card technology has made great advances, and people have invented innovative ways of using them, which include tracking credit purchases, record-keeping that took the place of paperwork, among others.

For example, in the US, consumers have been making use of smart cards for all commercial activities, such as buying groceries, ordering items online via smartphones, visiting libraries, attending movies, just to mention a few.

Smart card applications cut across many sectors and industries, ranging from banking, transportation, to telecommunications, domestic purpose, and even in government agencies. We’ve firmly integrated the smart card technology into virtually every activity in our daily lives, obviating the need to carry cash on a person. Many a state in the United States has made things a lot simpler by including chip card programs for government applications, which range from traffic departments to electronic benefit transfers.

A lot of industries have equally adopted smart card technology in their products, like GSM digital cellular phones and TV-satellite decoders. Indubitably, smart cards have a wide variety of applications in modern times, stretching across many different fields.

One of the most prominent and relevant smart cards applications is in SIM Cards and telecommunication, where they are also called secure elements, allowing the safe and secure operation of network traffic, through the provision of security technology for several millions of subscriber identity modules (SIMs) on a yearly basis. Smart cards are consumed which help the unique identifier, stored in the SIM card to protect the rights as well as privileges of all mobile subscribers.

In 2017, Brussels, Belgium-based Eurosmart reported that 5.6 billion secure elements, would be shipped globally for applications in the telecommunications sector. Eurosmart estimated that in 2018 secure element shipments for applications in the telecommunications industry would grow to 10 billion.

In a Nutshell

The technology behind smart cards has many uses today and some potential benefits for the future. With this tool — contact or contactless cards; memory or microprocessor-based cards — so many organizations and individuals now seamlessly maintain a business relationship between clients, suppliers, vendors or government authorities. They are equally capable of use, either as portable storage devices or for different purposes entirely, as they possess the capacity to hold more data in various forms.

Network Virtualization: What is it exactly and why is it useful?

Network Virtualization. What is it exactly and why is it useful? In a nutshell, network virtualization combines hardware and software resources into a single administrative entity. Its purpose is to enable a data center or service provider with the applications they require on a daily basis.

But What Makes NV So Special?

All businesses aim to achieve efficiency, flexibility and cost savings. Network virtualization fulfills those. Additionally, it also provides security. In a world where malware, hacking, and data breaches are common, eliminating these possibilities is crucial.

Behind The Network Virtualization Scenes

For the last ten years, enterprises have been embracing virtualization technologies at a fast pace. Network virtualization decouples networking connectivity and services, which were previously delivered through hardware, into a dynamic, logical virtual network.  Network virtualization helps address a large number of networking challenges within modern-day data centers. It also assists with consolidating any on-demand programming and provisioning of businesses networks while eliminating the need of making any physical changes to the primary infrastructure. Network virtualization allows enterprises to simplify the way they roll out, scale, and regulate workloads and resources for effective management of ever-increasing computing requirements.

The primary objective of advancements made in the field of virtualization is to automate and ease the physical management required. In physical environments, the addition of switch ports demands connections and configurations through cabling along with the additional cost of actual switch ports. A switch port can be created separately from the primary physical ports with virtual settings. Making it an ideal solution if a company requires multiple virtual switch ports.

Why Should Your Company Use Network Virtualization?

Aside from efficiency, flexibility, and cost reduction, a company can create and configure an entirely new logical network while using the existing physical hardware. This new logical network can be independent of the other virtual networks even though it also utilizes the same equipment including cables, routers, switches, etc. Network virtualization allows for the facilitation of complex needs within multi-tenancy settings while maintaining complete security. It can keep the traffic of each network into a different logical zone and prevents it from mixing with other resources.

By allowing multiple heterogeneous network architectures to cohabit on a shared physical substrate, network virtualization provides flexibility, promotes diversity, and promises security and increased manageability — all at a lower cost to you regarding physical hardware.

Network Deployment: 3 Best Practices

It can be extremely challenging to manage an enterprise network. Or any network for that matter. Most businesses are heavily dependent upon real-time data sharing, online transactions, and operational processes making network systems a critical component to ensuring business efficiency. From backup and load balancing to stringent security controls, the quality of every aspect pertaining to the network is heavily dependent upon an effective deployment process.

Below are some best practices related to network deployments that your business must know.

Embrace the power of Ethernet

We have seen an unprecedented improvement and progress in the ability of Ethernet in the last decade. Networks that power over Ethernet offers greater scalability, flexibility, and reliability to enterprises, supplemented by the improved security provisions. The installation involves a simple routing process using Ethernet cables compared to complex VPN and MPLS setups. Business Ethernet also supports the existing network configuration. Carrier Ethernet can handle massive volumes of traffic and facilitates in high-speed connectivity of data centers to transfer substantial data loads efficiently. Moreover, Carrier Ethernet is easily upgradable and helps an organization cope with adaptive networking and ever-changing application and service demands.

Copy physical media to a hard drive

To keep it short and sweet, copy your physical media to a hard drive. This will accelerate the process of the deployment while immunizing the risk of errors and file corruption. Using this practice will also ensure that no communication errors occur and data installation is performed smoothly without any bugs or connectivity issues related to private networking.

Use a Uniform Naming Convention (UNC)

When specifying network paths during the deployment, using a Uniform Naming Convention (UNC) instead of mapped drive letters can be extremely beneficial. Each computer has different mapped drive letters and utilizing UNC paths help to navigate this problem and facilitate error-free network deployment. An example of a UNC path is using “\\server\share\folder” instead of “E:\folder”.

Final Thoughts

Using the techniques as mentioned earlier and other best practices and data solutions will allow you to avoid bottlenecks and issues related to deployment and enable you to get your network up and running swiftly and smoothly.

4 Ways Ethernet Boosts Data Center Needs

Data centers are continually searching for ways to push more data at a faster rate. The increased demand for swifter enterprise-class data transport has resulted in substantial changes in Ethernet speeds in the data center.

Carrier Ethernet has become the networking norm in the past few years as customer data-center servers are required to handle the massive amount of traffic from smarter, data-intensive applications, IoT devices, and more. 

The Need For Increased Speed

Most hyper-scale data centers are equipped with 100 Gigabit Ethernet (GbE), and it is anticipated that they will move to 200 or 400 GbE by 2021. Moreover, there is an expectation that they will move from Gigabit Ethernet to Terabit Ethernet in the next few years.

If we talk about enterprise data centers, they are trying to catch up as currently, we have only seen 10 GbE, which is much slower for adaptive networking, especially in this demanding business environment. However, as the Ethernet speeds are increasing at an accelerated rate, it is likely that we will see enterprise data centers upgrading to at least 100 GbE.

There are many reasons why data centers require higher speeds, the primary one being the significant growth of hyper-scale networks from tech giants such as Amazon, Facebook, and Google. Furthermore, the availability of higher Gigabit Ethernet products at a lower price has also amplified its demand, supplemented by an increased amount of data load and private networking.

Adaptive Networking

In addition to that, workloads are becoming more adaptable and flexible as organizations branch away from the conventional enterprise data center. Enterprises are becoming more mobile, more distributed and more hyper-scale oriented, which further warrants the need for adaptive networking and fast speed in data centers.

Other important reasons include usage of data for multiple applications, including, but not limited to, financial trading, traffic management, car and airplane design, private networking, social media drug discovery, and even national security. Most data centers are considering fiber backbone for their Ethernet cable to support increased GbE speeds, higher bandwidth, and future expansions.

Another important reason is the requirement for fast and high-speed ports and an increased amount of data being driven from the dense edges of the network, which is further driving the advancement in this area. It will be fascinating to see how high-speed Ethernet boosts data center needs in the future.
