Why You Absolutely Need a Firewall for Your Website

Why You Absolutely Need a Firewall for Your Website
With the average data breach costing around $3.6 million, it's vital that your company is safe from any nefarious actors. When a hacker gets into your servers, they can take control your system and all its users. You desperately need a firewall to ensure your customers and company are well protected.

With the prevalence of ransomware like the widespread WannaCry hack in recent years, hackers have gotten more sophisticated. As ransomware gets easier to deploy, smaller systems and companies are at a higher risk. A hack could damage your brand, your public perception, and even lead to lawsuits.

If you're not sure if you need a firewall, you should get to know more about what kind of insurance they can offer.

Here are three reasons to consider a firewall.

1. Protect Your Assets

The work that your company does likely resides on your company's servers. If you create any copywritten material or digital projects, a hacker could get ahold of your licensed material and distribute it for free.

Media companies that create films, music, and other media could lose profits when data goes out before it's planned release date.

You could also put sensitive employee communications at risk. If you're in the middle of any kind of legal settlement, those details could put the whole deal in jeopardy. You need to protect your employee communication as intently as you protect your financial assets.

2. Protect Your Users

If you have user data stored in your system, you should treat that with care and respect. The payment information that users keep on your servers is expected to be safe and secure. If hackers can breach a firewall and get to it, your reputation could be severely damaged.

Failure to protect your users could lead to a lawsuit or a general distrust, the losses of which are hard to calculate.

3. Be A Step Ahead Of The Competition

Not every company prioritizes the importance of securing their users' data. If your competitors get hacked, you can be the company they turn to for all of their needs in your industry. With your competitors marked as unsecured, you'll be able to take advantage of a gap left in the market.

Users that were the victims of poor company practices will be wary about working with another company. Offer them a discount in response to the costs they'll be accruing due to their compromised data.

You Need A Firewall

With all that could go wrong with anything from unsecured wi-fi networks to negligent employees, you should implement a firewall. A firewall will ensure that your company's communications stay within the company. You won't be walking down the street and see a competitor has suddenly got a product that looks and acts just like the product you were working on.

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.

Different Systems
There are a few different systems for network forensics. Each comes with pros and cons.

·        “Catch it as you can” systems: These types of forensic systems pass all packets through a specific traffic point. The packets are written to storage and the analysis is performed later in batches. This system allows comprehensive visibility of all traffic in the past but it also requires larger amounts of storage.
·        “Stop, look, and listen” systems: Each packet gets analyzed in a simple and basic way and only specific information is saved for future analysis. This type of network forensics requires less storage but faster processing speeds to keep up with traffic.
