The fast evolution of computer networks brought fantastic developments for communication and connection capacities.
We can easily see this evolution while observing the Internet, first a restricted network and now a complex and global network, where we can do a simple mail exchange or complex and elaborated financial transactions.
But, we also have the dark side of this fantastic environment: threats like virus, worms and Trojan horses, scanning, spoofing, sniffing or snooping, and so many others became the nightmare of all organizations.
Indeed, the technology can play for and against us.
A good way to make the technology works for us is using Packet Inspection. This is a tool frequently used to sniffing networks, looking for password and breaches, but information security professionals can use it to do exactly the opposite: protect the network.
With a good Packet Analyzer you can generate information about your integrated information systems, supporting the system administrator to find and solve the problems in a quick and efficient manner. It’s possible to identify attacks, non-authorized access to systems and malicious behaviors. In other words, with a good inspection solution your organization will be able to see and analyze everything that hits your network.
You can prevent problems and also reconstruct network sessions, providing the needed information for Network Forensics. It’s when the hunter became the hunted: you will be using the same method malicious threats use to put your business under risks to defend your organization.
