Network Security with a Firewall

At Cadamier Network Security Corporation in Denver, we understand the value of network security with a firewall. Firewalls, which continue to evolve and improve, have become very commonplace as they are a proven defense mechanism against an increasing and changing variety of cyber-threats. Today, we discuss a few details to help you better understand how firewalls can protect your business.

What is a Firewall?
Think of a firewall as perimeter fences. Basically, they monitor incoming and outgoing traffic to determine whether it should be allowed or blocked. Firewalls have become increasingly sophisticated and can now implement control policies and more thoroughly inspect packets of traffic. Additionally, firewalls can perform tests on packets to determine if they are safe.

Stateful Firewalls
Stateful takes network security with a firewall to another level, allowing traffic examination to be performed more holistically. For example, this approach can configure your firewall to allow some traffic through for certain users while at the same time blocking other traffic for other users.

Next-Gen Firewalls
Firewalls that have integrated more advanced features are referred to as next-generation firewalls. These more advanced options can include the integration of intrusion detection and prevention as well as encrypted traffic inspection.

If your business needs to improve its network security with a firewall, contact us here at Cadamier in Denver. We have all the solutions you want and need for your business.

Proxy-Based Firewalls
These firewalls act as a gateway between end users (requesters) and the source of the data. With a proxy server, all traffic is filtered before it arrives at the end user. This protects end users, who are often clients, from threats by masking requester identities.

Web Application Firewalls
Instead of sitting at an entry or exit point, web application firewalls are located in front of specific applications. These firewalls are intended to protect application servers.

Firewall Hardware
Firewall hardware is generally a server that is able to be a filtering router while running firewall software. Multiple servers can be used throughout a system to handle the capacity needed for a business.

Firewall Software
This is generally the central manager of firewall deployment. Your software can be used to configure features, control analysis, and implement your cybersecurity policies.

Intrusion Prevention Systems (IPS)
To better accomplish the finer points of cybersecurity measures, a number of companies are using next-generation firewalls in conjunction with IPS products. This combination can help companies perform signature tracing and improved anomaly protection. The combination allows companies to better prevent threats from entering corporate networks.

This is a feature that has started to be included in some next-generation firewalls. This allows the firewall to contain unknown traffic or coding and run it in a test environment. This allows your security to better determine when such traffic is going to cause your company trouble.

If you need to improve your network security with a firewall or upgrade your existing firewall arrangement, contact us here at Cadamier in Denver. We can help you improve your cybersecurity and better protect your business.

Why You Need Log Collection and Security Reporting

Here at Cadamier Network Security Corporation in Denver, we want to share more about why you need log collection and security reporting for your business. Regardless of the size of your organization, these are important components used in monitoring your network for vulnerabilities and attacks.

Purpose of Logs
Log data is a great way to help you ensure that your data security methods are proactive. They also help you make it more difficult for someone trying to breach your security systems. Log data can help you analyze and understand what occurs within your network regularly and this can help you expose attacks and identify the damage done quickly. Each log contains valuable information that can be incredibly useful if you know how to use and analyze each one.

Log data can even help you find breaches in your security in real-time rather than after the damage has been done. Log management systems can help you achieve accurate real time analysis which can help you create real-time responses to cyber-security threats. For example, users can be logged off and the system can be shut down in response to a threat.

Analyzing and Monitoring Logs
Having a log can help you establish what is normal for your networks and this is an important step in allowing you to identify abnormal logon activity. Abnormal activity can then be analyzed using log management. This will enable you to understand root causes for abnormal activity and correlate events and log activity from many devices simultaneously. This can be a great benefit to your business’s security.

While you may understand the need for monitoring servers, firewalls, and network devices, you may benefit from monitoring workstation logs as well. Workstation logs can also give you key information. It can tell you, for example, if someone connected a USB, when it was connected and whether it was an authorized connection. This may help you establish if an employee is doing something unauthorized or breaking your cyber-security protocols.

If you need assistance with log collection, analysis, and security reporting, contact us here at Cadamier in Denver. We can help you with your network security needs and improve your company’s cyber-protections, including log creation and management.

Logs for Auditing
Creating logs, storing them, and analyzing them allows you to create a security audit trail. While these trails are mainly used for security purposes, they can be used for other audit purposes as well. To audit log files effectively, it is likely that a log file management solution will be needed. Log analysis software can automate what may seem like an impossible task and it can make your log management effective and timely while increasing your cyber-security.

If your business is looking for effective log file creation and security reporting, contact us here at Cadamier Network Security Corporation in Denver. We can provide you with the log management security solutions you need. Now that you know why you need log collection and security reporting, contact us for the best solutions for your business and security needs.

Network Security and Protecting Customer Data

Network Security and Protecting Customer Data
At Cadamier Network Security Corporation in Denver, we know the importance of network security and protecting customer data. If data that you collect or store is leaked, even if it is inadvertent, you could be held liable. Here are some ways to better protect your customer’s information as well as your own business.

Point of Sale Security
Making sure that a customer’s data is protected at the point of sale is becoming increasingly important. You may have noticed that the U.S. is now on the list of countries that are moving away from magnetic strip technology in favor of a more secure chip. This has resulted in an increase in fraud for cards that use this soon to be outdated method. The data that has been stolen from these cards now have a limited life and hackers are eager to use the data before it becomes obsolete. Making your system tamperproof at the point of sale is a great way to protect yourself and your customers.

Encrypt Your Data
Data encryption is incredibly important in cybersecurity. While is it best to keep hackers from gaining access to your data, encryption protects the data by rendering it useless even if a hacker manages to get it. Not only is data encryption important but your encryption needs to be regularly updated to maintain its effectiveness.

If you need help ensuring your encryption is regularly up to date, that your data is secure, and your customers are protected, contact us here at Cadamier in Denver. We can help your company with all its cybersecurity needs.

Choose Your BYOD Policy Carefully
Some companies love the BYOD (Bring Your Own Device) era. They enjoy that it can lower a company’s costs and increase employee satisfaction. BYOD can also substantially increase your cybersecurity risks.

One of the real issues with BYOD is the number of entry points that are created. Every device is an opportunity for a hacker. In order for BYOD to work for your company, you need to be clear about the type of data that can be housed on a personal device and make sure you have a method for ensuring network policy is followed closely and effectively. Depending on your business, you may choose not to allow BYOD to minimize the issue.

Remember Your Paper Documents
Criminals and hackers still like to use traditional methods for accessing your customer’s data. This is why it is still very important to ensure your paper documents are protected, particularly when it comes time to dispose of them. Companies that collect and possess consumer information are legally responsible for ensuring proper disposal. All sensitive information must be destroyed properly, such as by shredding them or burning them.

If you want your customers to feel secure about sharing their information with you, excellent network security and protecting customer data are musts. Here at Cadamier in Denver, we can help you have the best data security possible and ensure that your customers and your business are protected.

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.

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.
