Networks have various points of entry that need close monitoring with adequate security built around them: travelling staff need constant access from various remote locations, mobile and smart devices of increasing complexity are arriving on the scene almost weekly and wireless networks that bring their own set of security considerations. Today’s networks need to be so much more dynamic and flexible to accommodate constantly moving trends and new developments.

This week we’ll cover how a firewall log analyser assists in keeping security vulnerabilities at bay and optimise the traffic flow through your environment. Firewalls don’t only keep malicious software on the right side of your network, they also play a big role in the analysis of network traffic that aids in the design, expansion and optimisation of your environment.

The internal and external security vulnerabilities in today’s network makes it impossible for IT staff to plug vulnerability as it arrives. Constant monitoring andevaluation of network traffic makes it possible for engineers to understand the nature of data traversing the network. Fast analysis of real-time network metrics gives real meaning to proactive monitoring. Firewall log analyzers provide clear and comprehensive insight to network behaviour patterns such as bandwidth usage, user browsing, security vulnerabilities and application performance metrics.

Here’s how a firewall log analyzer helps you get peak performance from your network:

1.  Monitor bandwidth usage: When bandwidth issues are causing the business to suffer, IT engineers need to understand where the root cause lies. Your firewall log analyzer will provide insight to how bandwidth is consumed by applications and users. This allows you to identify problem areas in your environment and take corrective steps. User browsing habits can be the cause of many hours spent unproductively; ultimately resulting in lost revenue. Log analysis allows you to identify bandwidth misuse and stamp it out.
2.  Help meet compliance: Depending on the line of business in which your organisation functions, legal compliance around data security may be a very large concern for you. Use your firewall log analyser to identify compliance shortcomings and implement changes to ensure regulatory compliance.
3.  Eliminate vulnerabilities: Minimise security threats such as network intrusion, virus attacks, denial of service (DoS) attacks through early detection. Your firewall log analyser will reveal pertinent information around the type of traffic coming in and out of your environment.
4.  Capacity planning: It is vital for IT engineer and managers to pick up on trends and the effects it has on the environment. Network and Internet traffic trend analysis allows for informed decision making involving expansion undertakings. Also, shaping traffic according to business needs requires an understanding of how bandwidth is consumed.

A firewall log analyzer brings tighter security with deeper insight.

 It is a mistake to think that simply installing a firewall takes care of your security needs. The wealth of information available in firewall logs are invaluable to IT engineers and managers who want to keep their networks safe and running at peak. The trick is to make all that information simple and easy to digest, and this is where log analyzers come in. Taking large volumes of network metrics and repurposing it into easy-to-understand information gives IT professionals the insight they need to ensure they build networks that are fast, secure, robust and compliant.
