Firewalls & Security

Detect, analyze, and prevent ransomware, advanced threats, and targeted attacks

Enterprises need to make an NGFW (Next Generation Firewalls) purchase decision based on need, risk and future growth. Don't buy a Cadillac if a Chevy pickup truck will do the job.

Intrusion Detection Systems & Firewall Configuration Services

Every computer is always at risk for unauthorized access and intrusion, however, businesses with sensitive and private information are at a higher risk.

Every computer is always at risk for unauthorized access and intrusion, however, businesses with sensitive and private information are at a higher risk. While the occurrence of intrusions may be rare, this can be a costly problem for any size business as confidential and important information may be stolen or destroyed. It makes any organization vulnerable to theft or even legal action. We can help improve your computer network security by using firewalls and intrusion detection systems. Firewalls are set up at multiple levels to provide protection for servers, networks and individual devices.

  • Intrusion detection systems help information systems and networks to prepare for and deal with attacks by collecting information from a variety of network systems and analyzing and monitoring this information for possible security problems.
  • Firewalls are software or hardware based systems that act as a barrier against unauthorized access to a computer system.

Implementing Intrusion Detection Systems

One of the computer network security services that we offer for small and mid-sized businesses is to implement and monitor intrusion detection systems.

One of the computer network security services that we offer for small and mid-sized businesses is to implement and monitor intrusion detection systems. Intrusion detection systems monitor network and system activities in order to prevent attacks and malicious activities that can come from within a network. Typically, intrusion detection systems will notify the network administrator when suspicious activity has been detected. In some cases, the intrusion detection systems can take action when problems are detected such as barring a user or IP address from accessing the system.

  • Intrusion detection systems typically provide the following services:
  • Monitoring and analyzing user and system activity
  • Auditing system configurations and vulnerabilities
  • Assessing the integrity of critical system and data files
  • Performing statistical analysis of activity patterns based on matching patterns with known attacks
  • Analyzing abnormal activity
  • Operating system audits

Firewall Configuration Services

Firewalls

A firewall is another important part of computer network security. Like intrusion detection systems, firewalls can help strengthen any business' network security. However, firewalls differ from intrusion detection systems largely because they look outwardly for intrusions into a network in order to stop them from happening.

When implementing a firewall as part of your network security system, it is important to understand that a firewall must be configured properly in order for it to be effective. Steps involved in proper firewall configuration include setting firewalls to monitor incoming and outgoing packets, utilizing adequate firewall hardware or software for your needs, and standardizing wireless connections on a WPA.

What Is The Difference Between a Hardware & Software Firewall

Software Firewalls

There are two types of software firewall, Server based and Client PC based. Server based software is when you install a centrally managed application which will search the network for PCs connected to that network. Client based software is when each pc has its own software and each pc updates itself.

There are two types of software firewall, Server based and Client PC based. Server based software is when you install a centrally managed application which will search the network for PCs connected to that network and install clients with software that will protect them from viruses, spyware, Trojans and so on. This means the server is protected and so are the client machines. Server based software puts less strain on Internet bandwidth because all updates are done by the server only and then the server pushes the updates to the client machines. This ensures all networked PCs are protected in the same manner. This is particularly good if end users have laptops which they take off-site and connect to the Internet at home etc and then bring their laptop to the office. Client based software is when each pc has its own software and each pc updates itself. If you only have a few PCs and no server, this is a simple means of protection.

Hardware Firewalls

Hardware firewalls are easier to deploy and protect the entire network by acting as the first line of defense against anything trying to come in over the Internet.

Hardware firewalls are easier to deploy and protect the entire network by acting as the first line of defense against anything trying to come in over the Internet. First you have your Internet router and then you have the firewall, so ALL Internet traffic gets scanned BEFORE it gets into the network. All emails are scanned for attachments that might contain viruses or links to bad websites. Anything bad is stripped out or the email is prevented from being delivered. Hardware firewalls protect everything that is inside the network. The negative is that should laptop users take their machine off-site and get a virus, once they bring the laptop back INSIDE the network, the firewall is no longer effective so laptops etc will need another line of defense.
