ntop users have started to use our tools for malware analysis as contrary to packet sniffers or text-based security tools, ntopng comes with a web interface that simplifies the analysis. For this reason we have recently: Added the ability to upload a pcap file to ntopng using the web GUI, so that you can analyze […]
Using Blacklists to Catch Malware Communications Using ntopng
A category list is a control mechanism used to label traffic according to a category. In nDPI, the traffic classification engine on top of which ntop applications are built, there are various categories including (but not limited to) mining malware advertisement file sharing video streaming A blacklist is a list of IP addresses or symbolic […]
Traffic Monitoring and Enforcement for ISPs and Service Providers
Last week we have talked at ITNOG6 where we presented a report of the lessons learnt while monitoring ISP and service providers networks. This work is the result of one year of activities carried on with some of our users who provided feedback and new ideas. In summary we concluded that cybersecurity is a hot […]
HowTo Use ntopng for Pcap Analysis
Many times traffic analysts receive pcap files containing some traffic to analyse. The usual steps for analysing the pcap file with ntopng have been for a long time: Save the pcap file to disk and upload it to the host where ntopng is running. Stop the ntopng service and restart it from shell as ‘ntopng […]
Introducing nTap: a Virtual Tap for Monitoring and Cybersecurity (including Wireshark, Suricata, Zeek, OpenvSwitch)
This is to announce a new product named nTap that implements a software tap, to be used in physical and virtual/containerised environments. Using nTap with ntop applications nTap with Third Party Applications nTap allows you to capture and deliver packets using a secure and encrypted communication channel from remote hosts to a collector host […]
HowTo Implement Flow Relay, Replication and Fanout with nProbe
Sometimes flow (sFlow/NetFlow/IPFIX) collection can become a complicated activity when you need to: Collect, on your private network, flows originated by devices with a public IP. Migrate your infrastructure to nProbe/ntopng while sending flows to both nProbe and your legacy collector. Implementing all this is often an expensive exercise with non-ntop solutions, therefore in order […]
HowTo Select the Right Network Adapter for Traffic Monitoring and Cybersecurity
Since the introduction of PF_RING ZC drivers for Mellanox/NVIDIA, and the new family of Intel E810 adapters, the activity of selecting the best, cost-effective adapter, based on the use case and the performance we need to achieve, has become more complicated. Let’s try to shed some light. Intel Adapters Most commodity adapters, including Intel and […]
What is CyberScore and How it Works: a Technical Overview
ntop users as familiar with concepts such as flow risk and cyberscore. This week we have presented a conference paper [slides] at 2022 IEEE International Conference on Cyber Security and Resilience where we describe in detail what is cyberscore, how it works, and how we have validated it in real life. In essence this is […]
Introduced RHEL/RockyLinux 9 support (and new GPG Package Signing Keys)
This is to announce the availability of ntop packages for RedHat EL9 / RockyLinux 9 at packages.ntop.org. This has forced us to change many things in the way we build packages due to the deprecation of the SHA-1 algorithm. Because of this we had to modify the GPG signing keys used to sign the ntop […]
Welcome to ntopng 5.4: Enhanced Traffic Analysis and Cybersecurity
The previous stable release introduced a new persistency layer based on ClickHouse, paving the way for a more flexible yet fast historical data analysis, with its ability to store billion of records (alerts and flows) with limited disk space and very low query time. This new 5.4 release introduces many enhancements in the historical data analysis […]
