Network Security Essentials for Small Businesses

Network Security Essentials for Small Businesses Cadamier Denver
Here at Cadamier in Denver, we want to share a bit about network security essentials for small businesses. Sometimes, small business owners think that cybercriminals only go after big companies. Unfortunately, this can put them at risk. Powerful network security can protect you from empty accounts, as well as stolen business and client information.

Sometimes, cybercriminals seek out smaller businesses specifically because they tend to lack high levels of security. If you want to protect your company, take a look at our list of network security essentials for small businesses.

Use Some Security Basics
Small businesses need to change their thinking to be more reflective of big businesses. For example, small business should follow rigorous guidelines for system and data safety. Some of these guidelines include:

·        Install firewalls for both wire-based access points and wireless access points.
·        Install anti-malware on both servers and endpoints.
·        Install spam filters. This will help keep out phishing emails.
·        Install patch updates for applications and operating systems as they are issued.
·        Install white-listing. This will help prevent inappropriate software downloads.

Backup Your System Regularly
There are a number of ways your systems can be damaged. Malware, hackers, floods, fires, earthquakes, and even bad employees can cause problems for your system security. Disaster recovery is key to cybersecurity and can only be successful if your system is regularly backed-up and the back-ups are monitored for success.

Train Employees
Employees are a line of defense for your business. Training them is an important step in ensuring that your employees are able to help maintain your cybersecurity. Employees who lack cybersecurity training are frequently the cause of security breaches.

Creating policies to help your employees understand your network security needs and expectations is a good way to protect your business. Check their compliance and repeat training regularly. Also, consider penalties for failure to comply with your security policies.

Mobile Device Policies 
Your cybersecurity needs to include mobile devices in addition to your own computer system. Determine appropriate access and balance the needs of your business with the personal data use of your employees. If you need help determining the best policies and procedures for your business, we here at Cadamier in Denver can help. We can also help you with various aspects of your cybersecurity needs and provide comprehensive packages for your business’s needs.

Protect All Your Data
You need to know where your data resides: cloud services, mobile devices, desktop computers, and servers. You need to be sure that all the locations have network protection. You even need to be concerned about disposal of your data to ensure that old devices will not pose a security risk to your business. Don’t forget about disposal of sensitive paper documents. Proper shredding and disposal are still important in the digital world of today.


Keeping track of all the network security essentials for small businesses can be hard. Here at Cadamier in Denver, we can help your small business have the big business security it needs to be safe and protected.

How to Protect Yourself After the Equifax Breach

How to Protect Yourself After the Equifax Breach
Here at Cadamier Network Security in Denver, we want to share how to protect yourself after the Equifax breach. Unfortunately, it’s highly likely that your personal information was part of the recent data breach. In fact, 143 million people may have had their information exposed, including names, birth dates, social security numbers, driver’s licenses, and more.

At Cadamier, we’ve been watching this situation unfold and wonder what steps were taken to ensure network security. With the right precautions taken, it’s quite possible that this could have been prevented. And it’s certainly a cautionary tale for businesses of all sizes to invest in proper data security and intrusion prevention.

Needless to say, here we are and you may be trying to figure out what next. Let’s take a look.

Those who also had their credit card numbers (209,000 people) will be notified directly about the breach. Everyone else must visit the Equifax site and use their last name and their last four SSN digits to determine whether they were affected. If you are affected you may want to take the following precautions to protect yourself after the Equifax breach.

Order Your Credit Reports
Get your free copy of your credit report (you are entitled to one free report annually per agency) from TransUnion, Equifax, and Experian. Your credit report will show who has requested your report, which is a sign your information may have been used to open a line of credit or obtain a loan.

A lack of requests doesn’t mean you are safe. It just means that it isn’t on your report. Sometimes, it can take a while for items to make it to your report. Some activities, such as stolen money or suspicious credit card purchases will not show up on a credit report.

Fraud Alert on Credit
Contact one of the credit reporting agencies and place a fraud alert on your reports. Whichever agency you choose is then required to contact the remaining agencies. The alert is good for 90 days and is renewable.

Examine Your Bank and Credit Statements
It is important to look over all of your statements carefully so that you can spot suspicious activity. Look for small amounts of money stolen across your accounts. You can also have a financial advisor or your lawyer look over your statements to help you spot unusual activity. Be sure to check your accounts every month.

Sign up for Identity Theft Protection or Credit Monitoring
Monitoring services are helpful but are not foolproof either. Such services track your credit and alert you to credit requests and new accounts, but they do not alert you to suspicious activity. Many of these services also include identity theft protection, which is helpful and will monitor utilities, social media, and payday loan applications.

Many monitoring services have a fee, but Equifax is offering one free year of monitoring through TrustedID Premier. This service will track your credit reports and provide you with free copies. It will also scan the web for use of your social security numbers and includes identity theft insurance.

Freeze Your Credit
This is an extreme step, but it blocks anyone from accessing your credit reports without your express permission. While it can be effective in stopping new accounts, it can also be inconvenient to you because you have to contact the company to lift the freeze when you need a loan or credit card. There is a fee associated with these services as well.


Now that you know how to protect yourself after the Equifax breach, if you have a business and want to keep your data and customer data safe, use Cadamier Network Security Corporation in Denver. We offer the products and services you need to keep intruders out and prevent a similar event from ruining your company’s stellar reputation.

What Is a Firewall and Why Do You Need It?

What Is a Firewall and Why Do You Need It?
What is a firewall and why do you need it? Here at Cadamier Network Security, we realize that most people have heard of a firewall, but far too many people are not aware of the details of how firewalls work and how one might improve security for you or your business. Firewalls can be an important part of your network’s security and can also provide some additional benefits.

What is a Firewall?
A firewall intrusion products filter information coming in from the internet into a network or computer. Firewalls are frequently set up with filters that stop certain types of traffic. For example, firewall filters can help stop hackers from gaining entry to your network. Firewalls also prevent your employees from accessing sites they should not access while using a work computer. In a work environment, this can help curb some of the unproductive web searching habits of employees.

How Does a Firewall Work?
Firewalls control network traffic. The firewall can filter the flow of traffic to and from the network or computer. Firewalls can be customized to fill the specific needs of your business, and firewalls can work in different ways to achieve the filtering and protection such as packet filtering, stateful inspection, and proxy service.

Packet Filtering, Stateful Inspection, and Proxy Service
One way that firewalls can process information is in small packets. Packets, which are able to make it through the filters are allowed through while packets that do not make it through the filters are discarded. Stateful inspection is similar to packet filtering but it compares portions of the packet to already verified database information to determine if it is verified and trusted.

Proxy service acts as a gateway between networks, it can both be used to help improve security and to monitor traffic. Proxy services sometimes use caches of previously visited sites to improve traffic response time. Proxy service can also create mirrored sites to protect the location of information. Additionally, customizing firewalls can allow for adding or removing filters based on domain names, ports, IP address, or even words or phrases.

Why Use Firewalls
Firewalls alone may not solve all your security issues but firewalls can help with a myriad of security problems such as SMTP hijacking, spam, macros, redirect bombs, email bombs, viruses, backdoors, and remote logins. Firewalls and comprehensive security management can be customized to dramatically reduce your security risks and threats to your business. Firewalls can also help stop your employees from misusing their computers in the workplace.


Adding firewalls to your security is great but may require some time to adjust the customizations correctly for your company’s needs. It should also be just one part of your network security. If you want to improve your network security or if you need a current system to work better for your unique specifications, contact Cadamier Network Security in Denver. We can help you get the maximum network security and best designed WAN infrastructure you need.

Cybersecurity and Employee Buy-In

Cybersecurity and Employee Buy-In
At Cadamier Network Security in Denver, we see cybersecurity and employee buy-in as very important parts of your overall business security program. Cybersecurity is important to you and it should be just as important to your employees. Your employees can be a large security vulnerability in your organization. If your employees understand how important cybersecurity is to the protection of your organization, the vulnerability of your employees can become much smaller. Here are some tips on how to achieve better cybersecurity and employee buy-in.

Use “Live-Fire” Training Exercises
If your organization’s employees undergo a “live-fire” training, they experience cyber attacks as though they are real. Part of such training includes reviewing lessons learned from the experience as well as reviewing implications and possible prevention strategies for the future. For example, your IT team could regularly send fishing emails to employees to find out what happens. This can provide information about people or departments who need additional training. Over time, you can use the information to determine how well training is working and to find out what level of improvement has been gained.

Make Cyber Awareness Part of On-Boarding
New employees should experience cybersecurity awareness from day one. This emphasizes the level of importance of such security. Additionally, you should also ensure that your cybersecurity messages are continuous and repeated.

Perform Evaluations
Find out how vulnerable your business is to a cyber attack. Awareness of the strengths and weaknesses of your cybersecurity allows you to determine a clear path toward improvement. Testing also allows you to spot potential weaknesses you may not find otherwise. This can be a great way to determine how advanced of a firewall solution you need.

Have a Formal Plan
Create a formalized plan that encompasses your cybersecurity training. This plan should be executed, reviewed, and updated regularly. The updates should include a review of new risks and new cybersecurity concerns.

Get Buy-In
For a good cybersecurity plan, you need understanding, commitment, and appropriate and dedicated resources. This means you need buy-in from your employees, but also buy-in among all your leaders and executives. It is important that there is dedicated on-going funding supporting the budget, people, and security management needed for good cybersecurity.

Communication
For any cybersecurity plan to work, regular and clear communication with all employees is a necessity. All departments need to be on board with using best practices and completing training for your cybersecurity to function optimally.

Training Should Be Continuous
Because cybersecurity is a moving target, training needs to be offered throughout the year. The training also needs to be specific and tailored to an employee’s job. An IT employee is going to have very different cyber security risks than a customer service employee. Recognizing this and incorporating it into your training will improve your overall cybersecurity. Additionally, your cybersecurity training should be as up-to-date as possible to be truly successful.


Knowing how intertwined cybersecurity and employee buy-in are, we hope the above tips help you in improving your cybersecurity. If you need help with cybersecurity in your organization, contact us here at Cadamier in Denver.

Can Artificial Intelligence Help with Cyber Security?

Can Artificial Intelligence Help with Cyber Security
Our security experts at Cadamier Network Security in Denver are often asked: can artificial intelligence help with cyber security? We know cyber attacks are becoming more sophisticated every day. We can see the extensive damage done recently by the WannaCry cyber attack which shows the ongoing problems that governments and companies have not successfully addressed, despite being warned.

The cyber security industry is currently examining the ability of Artificial Intelligence (AI) to give organizations a quick and strong response to a cyber attack. It may have the ability to respond in real time when there is a cyber attack or data breach and could provide big advantages.
                                               
According to the Research and Development Branch of the Cooperative Cyber Defense Center of Excellence (CCD COE) and Estonian Academy of Sciences, the speed of processes and the amount of data that is used to defend the cyberspace may be too much to handle without automation. It is a challenge to develop software with conventional fixed algorithms (hardwired logic on decision-making level) to effectively defend against the constantly evolving attacks on networks. But the solution may be to use methods of artificial intelligence that add flexibility and learning capabilities to software. It’s possible to enhance cyber defense capabilities by increasing the intelligence of the defense systems. Some useful applications already exist.
           
Unfortunately, many businesses today are still using outdated network security techniques. Many people in the security industry are looking toward a new method of security which is based on Artificial Intelligence. Proponents of using Artificial Intelligence believe machines are far better than people at processing vast amounts of data and finding the hidden attacks. It is often pointed out that this need developed from the failure of signature-based techniques to be able to stop current threats, the huge amounts of security threat data; and the challenges of changing the size and scale as we address the security threat data.

Deep learning develops a machine to think more like a human with the ability to make decisions with great accuracy and this AI next-generation security products may be able to identify and kill malware as fast as the attackers can create it. The advantage of deep learning comes from the vast speed and processing power of modern computers. A deep learning algorithm paired with elastic cloud computing resources can consume hundreds of millions of samples of training data in hours. This may be able to create a neural network classifier so accurate and fast that it can outperform even highly trained human experts.

Artificial Intelligence may change security technologies and their design by being able to identify unknown malware from benign programs. This would be accomplished by training the deep learning neural networks on tens of millions of variants of malware, as well as known benign programs. According to a CNBC article, sometimes it takes days for organizations to realize their systems have been breached. This gives the hackers time to look for the crucial information inside the network. Cyber attackers not only steal data but they often alter data without detection. Cyber criminals often change their attacking methods with every target, which may limit the effectiveness of security defenses based on known files and attacks.


Our security experts at Cadamier Network Security in Denver help defend your organizations from network cyber attacks. Can artificial intelligence help with cyber security? As hackers and cyber attackers use more sophisticated weapons to steal information and hold data hostage, there will also be the need to improve responses and defenses. You can rest assured that our team will explore leading-edge AI options to find the best-fit security defenses for our clients.

5 Pillars of Network Security

5 Pillars of Network Security
Your business data is constantly under attack, that’s why you need Cadamier Network Security in Denver to implement the 5 pillars of network security to keep your information safe. Designing multiple layers of hardware and software security can prevent internal and external threats from damaging your computer networks and can contain attacks if they get around your defenses.

Today’s network threats include a host of problems including viruses, spyware, malware, adware, Trojan horses, worms, botnets, hacker attacks, data theft, among others. Cyber thieves are always looking for unpatched software and hardware, weak passwords, lost devices, unsecured wireless networks and websites, potentially unwanted applications, malicious users, and much more.

According to an IT Manager Daily article, there are five fundamentals of network security that you should set as a priority to prevent downtime, address compliance with government regulations, protect your company’s reputation, and reduce your liability. 

Inactive accounts
All inactive accounts that once belonged to contractors or ex-employees should be deleted because cyber hackers can use them to gain access and hide their activity. There is software you can use to clean up inactive accounts if you have a large network with lots of users.

Passwords
You need to create the strongest passwords possible and keep them safe. A strong password is six characters or more, uses both upper and lower case letters, and includes numbers and symbols. To increase password security, you should change your password every 90 days or so. You can set up a lock-out system where after a number of failed log-in attempts the user will be locked out.

VPN
If you have an open network connection it is vulnerable to hackers trying to get onto your network, it is important to secure a VPN by the strongest possible protocols for data encryption and identity authentication. Consider using a multi-factor authentication method. This may include a password and a PIN or a random code created by a key fob authenticator. You should also look into having a firewall that separates the VPN network from the rest of your network.

Patches and Updates
It’s important to keep all devices updated regularly, including network hardware and mobile devices because cyber hackers will target operating systems, software applications, web browsers and browser plug-ins if you haven’t kept patches and updates current. In addition, all computers should be updated automatically and should have the most current software versions.

User Access
You should actively manage your employees’ access privileges to your company’s critical data, making sure they do not have access to sensitive or confidential information outside the scope of their job requirements. If your employee’s job changes, make sure your IT manager restricts their access privileges to reflect only the duties of the new job.


In today’s cyber world, where your network and your critical business information is always under attack, you need to take the appropriate steps to address the 5 pillars of network security so your data is safe. Our experts at Cadamier Network Security in Denver can design hardware and software security to stop cyber threats and counter any breaches.

The Darknet Protects Itself by Being More Robust Against Attacks

The Darknet Protects Itself by Being More Robust Against Attacks
How the Darknet protects itself by being more robust against attacks is just one of the many recent issues Cadamier Network Security in Denver is staying up-to-date on. As part of our own efforts to safeguard our clients from threats, we wanted to pass along the latest news.

If you don’t know, the Darknet is a secret network which is often used for illegal purposes to stay hidden from the legal authorities. For example, drug trafficking communications and child pornography exchanges, or exchanging protected intellectual property free of charge often take place on the Darknet. The contents of the Darknet are not accessible through search engines. Basically, it is a part of the internet where both web surfers and website publishers are anonymous.

According to a Science Daily article, recent research by the Universitat Rovira i Virgili (URV) explains how the Darknet can counter large attacks on its own by spontaneously adding more network capacity. Researchers studied why cyber attacks are usually not successful against the Darknet, which guarantees the users' privacy and anonymity and thereby assures more secrecy for illegal activities on the internet. The Darknet’s enhanced privacy allows illegal operations to be conducted without anyone knowing and can defend against cyber attacks under most circumstances.

There are cyber attacks conducted by law enforcement agencies and others against the Darknet but they are usually not very successful. The URV researchers Manlio De Domenico and Alex Arenas from their Department of Computer Engineering and Mathematics have worked to figure out why the Darknet is so difficult to infiltrate.

In their recently published article in Physical Review E, the researchers discussed how the Darknet is almost impenetrable because of its unique topology. They examined the differences between the Darknet and the rest of the internet.

They used data published by the Internet Research Lab of the University of California in Los Angeles and network analysis to quantify the strength and resilience of the Darknet. They talked about the Darknet’s topology and came up with a model that demonstrated how information is transmitted using the onion router, a technique that encrypts messages in multiple layers.

The Science Daily article describes how this information allows the researchers to explain the ways the Darknet would respond to three types of attack:

·        Attacks on a particular node
·        Attacks that make certain nodes to fail randomly, and
·        Attacks that send a wave of errors that are propagated across the network

The study's results show that in order to really affect significant disruption, an attack on the Darknet's various nodes needs to be four times stronger than an attack against the internet's nodes.

In addition, they found the Darknet was able to very easily counter the waves their attacks through its different nodes by just adding more network capacity. They believe the Darknet’s resilience is attributed to a more decentralized topology that emerges spontaneously from the Darknet's onion router protocol. Whereas, the internet's structure is more heterogeneous.


Our computer experts at Cadamier Network Security in Denver specialize in the security of networks and computer information systems. We are on the forefront of network security issues including how the Darknet protects itself by being more robust against attacks. Everything we learn gives us the leading edge to help you.

Malware Turns PCs into Eavesdropping Devices

Malware Turns PCs into Eavesdropping Devices
Cadamier Network Security in Denver has recently learned that malware turns PCs into eavesdropping devices even without a microphone according to researchers at Ben-Gurion University of the Negev (BGU). If you’re concerned about this news (and you should be), our experts can make sure this is not happening to you. We are committed to network security protection, detection, and enforcement. We’ve been in business since 2001 and our job is to help business, governments, and organizations keep their information network safe and that includes protecting you from malware. 

According to Science Daily, which reports on research news, the new research paper titled, SPEAKE(a)R: Turn Speakers to Microphones for Fun and Profit, details and demonstrates how most PCs and laptops are vulnerable to this type of malware attack, which lets hackers change your headphones into a microphone and listen to your conversations.

An article in Daily Mail explains researchers have designed a code called 'Speake(a)r, which retasks a computer's outputs to inputs. This means it allows them without your knowledge to record audio even when your headphones are in the output-only jack.

Amazingly, the Ben Guiron University research team used a pair of headphones to capture vibrations in the air and convert them to electromagnetic signals in order to record audio from 20 feet across the room.

With malware, the research team used a common feature in most computers—RealTek audio codec chips. This allows them to get inside the computer and reverse its output function to input, which lets them to secretly hear your conversations.

According to an article at Cornell University Library, the malware can use a computer as an eavesdropping device, even when a microphone is not present, muted, taped, or turned off. A typical computer chassis has a number of audio jacks, in the front panel or in the rear panel or both. The jack is used for input, or for output. The audio chipsets in today’s motherboards and sound cards have an option for changing the function of an audio port with software, sort of like an audio port programming which is called jack retasking or jack remapping.

Professor Yuval Elovici is the director of the BGU Cyber Security Research Center (CSRC) and he is a member of BGU's Department of Information Systems Engineering. Elovici points out that since headphones, earphones, and speakers are physically built like microphones, the audio port in the PC and laptops can be reprogrammed from output to input allowing hackers to gain access to private information without your knowledge.

Several software countermeasures have been suggested, including disabling the audio hardware, using an HD audio driver to let the user know when microphones are being secretly accessed, and creating a rejacking policy within the industry. Another consideration is developing anti-malware and intrusion detection systems to monitor and detect unauthorized speaker-to-mic retasking operations and the block them.

In just another example of how malware can create dangerous information leaks and privacy invasion, researchers at Ben-Gurion University of the Negev (BGU) have shown how malware turns PCs into eavesdropping devices even without a microphone. Cadamier Network Security in Denver can help protect you and your business. Cadamier has provided Security Services for a wide range of clients including the DOD and the FBI and have been instrumental in providing network security reviews to organizations of all sizes. Cadamier continues to work closely with both state and federal regulatory authorities including the NCUA, FFIEC, and the DHHS in order to ensure that our clients are implementing the latest technologies and services to best protect their interests.

All About Adware and the Dangers it Poses to Your Business

All About Adware and the Dangers it Poses to Your Business
We all know what adware is. But at Cadamier Security Network in Denver, we believe you should know all about adware and the dangers it poses to your business. Many don’t realize that his software that displays advertising online has become very aggressive. Now, adware companies add more applications and often install whatever they want onto your system.

If you’re like many of our customers, you may just tolerate it instead of fighting it. Here’s the problem. Adware can install additional software without a user’s knowledge or consent and often is a risk for causing information leakage.

So, what type of information is leaked and how is privacy is being compromised? The main adware categories are ad-injectors, browser hijackers, and utilities that can change your system settings and lead to insecure configurations.

Sometimes it’s in-browser ad-injection, pop-ups, word highlights, or offering fake services with the goal of redirecting users traffic to their own websites for profit. They are distributed through software bundles. What happens is the user installs what they think is a legitimate application, but other applications are installed as well. Often the user can’t refuse the installation.

Let’s break these down a bit further.

Browser Hijackers
This kind of adware makes more modifications to the system than traditional ad-injectors, highlighting words, changing the default search engine, showing pop-ups outside the browser.

Utilities
Another kind of adware, utilities applications are shown as system optimizers and software removal tools. They trick you by showing fake problems on the system, such as an infection or poor system performance, in order to get you to subscribe to their service. But the problems simply do not exist.

Ad-Injectors
This type of adware modifies the content of the browser in order to display advertising that wouldn’t be there if you visited the website. The majority of ad-injectors are browser-based infections in the form of malicious browser extensions.

What happens is that once an ad-injector is installed on your system it will start injecting code in the visited websites which will load and display the desired advertising.

They will try to inject advertising into all the pages opened in your browser and the malicious browser extensions will monitor every page you visit. The applications will put many pieces of advertising on every page you visit. Critical information may be leaked about the user, such as visited news sites, intranet sites of an organization, username, activities, personal preferences, location, political ideology, and even more.

Leaked information can create many problems. There are three main problems associated with this information leakage that makes it even more critical:

Historical Visibility 
If you don’t stop adware, their servers are able to store your leaked browsing information for a long time. This can give them an accurate profile of your online behavior and activities.

No Encryption 
Your leaked information is sent through plain HTTP to the ad-injector servers. This not only exposes your information to them but to anyone that is watching your traffic.

Redundancy
Multiple ad-injection servers are storing your information in multiple malicious locations and that increases the opportunity for misuse by malicious actors.

The objections to ad-injector adware aren’t just about the advertising, although that’s annoying enough. More importantly, ad-injectors can leak information about the online behavior of your business activities and your company's personal preferences. The concern is these third parties receiving this information can misuse it and put your business’ security in danger.

If you use an ad-blocker or a script blocker it might help prevent the advertising to load and will protect users from the risks of the injected advertising. But here’s the problem – if you don’t see the advertising, you won’t know the infection is even there. You need to remove it, not hide it.


We believe you should know all about adware and the dangers it poses to your business. At Cadamier Network Security Corporation in Denver, we’ve been in business since 2001 and we are committed to network security protection, detection, and enforcement. If you have or suspect adware issues in any or all of your company’s computers or network, give us a call and let us help you protect your business.

Affordable 10 Gigabit Ethernet for Small and Midsize Business

Affordable 10 Gigabit Ethernet for Small and Midsize Business
When it comes to your business, it’s important that your network keeps up. Luckily, an affordable 10 Gigabit Ethernet for small and midsize business is now available and our experts at Cadamier Network Security in Denver can get you all setup. With this development and our help, migrating to 10 gigabits is easy on you and your budget. Soon, you’ll be on the fast track to growing your business!

To get you up to speed, let’s start with a quick definition that will provide deeper insight into 10 Gigabit Ethernet. This is information that you can also check out over at PC Magazine.

In simpler terms, we’re talking about an Ethernet standard that transmits 10 gigabits per second (10 Gbps). It was introduced in 2002 and is also be known as 10 GbE, 10GE or 10G Ethernet. This standard extended Gigabit Ethernet ten times for enterprise backbones, high-speed storage networks (SANs), as well as wide area, and metropolitan area networks.

Ten Gigabit Ethernet only works in full-duplex mode and does not support CSMA/CD, the usual Ethernet collision method utilized to gain access to the physical medium. A WAN interface sublayer (WIS) makes 10G Ethernet compatible with the SONET transport at 10 Gbps (OC-192). The 10GBASE-LX4 carries four wavelengths of light on one pair of fibers. Ten Gigabit Ethernet over copper wire was introduced in 2004 for short distances between data center switches and storage devices.

No matter what your business is, it requires a fast and reliable network. Your digital network needs to keep increasing from technologies like 802.11ac wireless, server virtualization, IP convergence, Cloud, and the Internet.

The key to taking advantage of affordable 10 Gigabit Ethernet for small and midsize business is to anticipate your growing network needs. A 10G network core will help improve employee productivity, allow faster customer response time, avoid network congestion, and introduce new products and services to the market faster.

According to a Computer Weekly article, if you have lots of gigabit connects to your desktops and laptops on your network, then you probably need something larger than a gigabit core backbone and server connections.

There are three components needed to upgrade your network to a 10G network. Those are access switches with 10G uplinks, 10G core switches, and 10G network interface cards for servers and storage devices. You can start by upgrading the core switches that you use to connect all your access switches together and connect your servers and storage devices. You may want two core switches stacked together to give redundancy and improve performance.

Now that your core switches are upgraded to 10G, you can migrate your key access switches and servers to 10G and connect to your new core switches. You should see an immediate performance gain in your network. You can upgrade the rest of your network to 10G whenever you’re ready or in step-up phases.


An affordable 10 Gigabit Ethernet for a small and midsize business network can be yours. Your company’s growing, why shouldn’t your network? Of course, if some of this technical jargon was a bit too much to digest, you can trust that our network experts at Cadamier Network Security in Denver are ready to upgrade your network to 10 Gigabit Ethernet. Contact us today to get started.
