In the absence of adequate tools and systems for collecting data and analyzing the behavior of a network, IT security professionals may face difficulties.
Greater awareness of the structure of one's network is instead fundamental to be able to intervene on the policies and make it more secure.
Corey Nachreiner CTO WatchGuard Technologies has focused attention on the issue by pointing out that "The more you know what's going on on your network, the better prepared you are to deal with hostile intruders, For this reason, WatchGuard suggests 4 tips to improve the security of a business system thanks to the visibility of the network:
Since network traffic varies for each organization, it cannot be measured in one way. The only way to detect abnormal and potentially dangerous activities is to have an understanding of what 'seems normal' to security officers. To do this you need visualization tools that regularly monitor the network, so that you may be able to detect irregular activities that could serve as an alert for some new or different event than usual
Through the use of visibility tools, it is possible to derive fundamental data to avoid a cyber-attack; these can provide data such as which server receives the most attacks, which users are associated with blocked malware and also other types of attack vectors. This will make it easier to restrict the scope of certain users for the benefit of security
Most connected devices receive a steady stream of network chatters such as automated malware. Thanks to the visibility tools it will be possible to install self-blocking security policies that stop the attack even before it is launched.
Visibility tools can help visualize network and policy flow. They can show how a particular type of traffic currently travels through its network, and what security policies that traffic affects. This helps identify many potential policy errors that may have been inadvertently committed.
The reality is that very few IT administrators have an accurate picture of what is going on on the network, and they do not have automated tools that can quickly identify, interpret and act on threats Network visibility tools help cybersecurity professionals discover things about the network and user behavior that had never been considered before.
Just to meet these needs, WatchGuard recently launched WatchGuard Dimension a solution that allows you to monitor the data traffic of your network in real-time and quickly and easily. The interface is extremely intuitive and consists mainly of tables and graphs that allow you to view potential threats and data traffic trends with a single glance.
