Network Packet Broker (NPB) and Network TAP are two different technologies in network monitoring and management. Each of them has different roles and functions.   Network (TAP)Test Access Point A network TAP is a hardware device that provides a direct and accurate way to replicate the actual packets flowing in the network for monitoring and analysis purposes. Taps are typically deployed at critical nodes of the network, such as switches, routers, or near servers, in order to capture packets flowing through these nodes. The main features of network TAP are:   Data replication: TAP is able to losslessly replicate network traffic, ensuring that the data received by the analysis tool is exactly the same as the original network traffic. Independence: As an independent hardware device, TAP will not interfere with or affect the normal operation of the network. Flexibility: TAP supports multiple types of network traffic capture, including full packet capture and deep packet inspection.   Network Packet Broker(NPB) Unlike network taps, a network packet broker is a higher level device that sits between TAP and SPAN (port mirroring) points and analysis tools and is responsible for directing raw packets to required security, monitoring, and performance devices. The main functions of NPB are:   Data Distribution: NPB is able to intelligently distribute data packets to multiple analysis tools, ensuring that each tool receives the data it needs. Filtering and transforming: NPB can filter and transform packets as needed to meet the requirements of different analysis tools. Centralized management: NPB provides the ability to centrally manage multiple TAP and SPAN points, simplifying the network monitoring and management process.   What's the difference between network packet broker and network tap? The main differences: Functional level: Network TAP mainly focuses on data replication and capture, while network packet broker focuses more on data distribution, filtering and transformation. Deployment location: Network taps are usually deployed on critical nodes of the network to directly capture packets. However, the network packet broker acts as a "mediator" between the TAP and SPAN points and the analysis tool. Management complexity: Network TAP is relatively simple and mainly focuses on data capture. However, the network packet broker provides higher level management functions, such as centralized management, intelligent distribution, etc.   In summary, network packet broker and network test access point each play different roles in network monitoring and management. Network TAP provides accurate data replication function, which is the basis of network monitoring. The network packet agent improves the efficiency and flexibility of network monitoring through intelligent data distribution and management functions. When choosing which technique to use, there are trade-offs to be made based on the specific network environment and monitoring requirements.

What is a Network packet Broker?   Why do I need a network packet broker? - Get more comprehensive and accurate data for better decision making - Tighter security - Solve problems faster - Increase initiative - Better return on investment   What exactly can the NPB do? - Redundant packet deduplication - SSL decryption - Header stripping - Application and threat intelligence - Application monitoring - Benefits of NPB for you   Keeping networks secure and users evolving in a rapidly changing IT environment requires a complex set of tools to perform real-time analytics. Your monitoring infrastructure may have network and application performance monitoring (NPM/APM), data loggers, and traditional network analyzers, while your defense systems utilize firewalls, intrusion protection systems (IPS), data leak prevention (DLP), anti-malware, and other solutions.   No matter how specialized security and monitoring tools are, they all have two things in common: - You need to know exactly what's going on in the network - The results of the analysis are based only on the data received   A 2016 survey by the Business Management Association (EMA) found that nearly 30 percent of respondents don't trust their tools to receive all the data they need. This means there are monitoring blind spots in the network, which ultimately leads to futility, excessive costs, and a higher risk of being hacked.   Visibility requires avoiding wasteful investment and network monitoring blind spots, which require collecting relevant data on everything moving in the network. The mirror ports of splitters/splitters and network devices, also known as SPAN ports, become access points used to capture traffic for analysis.   This is a relatively "simple operation," and the real challenge is how to efficiently deliver data from the network to every tool that needs it. If you only have a few network segments and relatively few analysis tools, then the two can be directly connected. However, given the ever-expanding speed of the network, even if logically feasible, this one-to-one connection has the potential to create an unmanageable management nightmare.   The EMA reports that 35% of organisations cite a shortage of SPAN ports and splitters as the main reason they are unable to fully monitor their network segments. Ports on high-end analytics tools such as firewalls can also be scarcer, so it's important to avoid degrading performance by overloading your device.   Why do I need a network packet broker? The Network Packet Broker (NPB) is installed between the splitter or SPAN port used to access network data, as well as security and monitoring tools. As the name suggests, the basic function of a network packet broker is to coordinate network packet data to ensure that each analysis tool gets exactly what it needs.   NPB adds an increasingly critical layer of intelligence that reduces cost and complexity and helps you achieve the following:   Get more comprehensive and accurate data for better decision making Network packet agents with advanced filtering capabilities are used to provide accurate and effective data for your monitoring and security analysis tools.   Tighter security When you can't detect a threat, it's hard to stop it. NPB is designed to ensure that firewalls, IPS, and other defense systems always have access to precisely the data they need.   Solve problems faster In fact, the time it takes just to identify an existing problem accounts for 85% of the average time to fix (MTTR). Downtime means money is lost, and mishandling it can have a devastating impact on your business. Context-aware filtering provided by NPB helps you discover and determine the root cause of problems faster by introducing advanced applied intelligence.   Increase initiative The metadata provided by the Smart NPB via NetFlow also facilitates access to empirical data to manage bandwidth usage, trends, and growth to nip the problem in the bud.   Better return on investment Smart NPB can not only aggregate traffic from monitoring points like switches, but also filter and collate data to improve security and utilization and productivity of monitoring tools. By simply handling the associated traffic, you can improve tool performance, reduce congestion, minimize false positives, and achieve greater security coverage with fewer devices.   5 ways to Improve ROI with Network packet Brokers   - Speed up troubleshooting - Detect vulnerabilities faster - Reduce the burden of security tools - Extend monitoring during an upgrade - Tool life - Simplify compliance   What exactly can the NPB do? In theory, aggregating, filtering, and delivering data sounds simple. But in reality, smart NPBS can perform very complex functions, resulting in exponentially higher efficiency and security gains.   Load balancing traffic is one of these functions. For example, if you upgrade your data center network from 1Gbps to 10Gbps, 40Gbps, or more, NPB can slow down to distribute high-speed traffic to an existing batch of 1G or 2G low-speed analytical monitoring tools. This not only extends the value of your current monitoring investment, but also avoids costly upgrades when IT migrates.   Other powerful features performed by NPB include:   Redundant packet deduplication Analysis and security tools support receiving large numbers of duplicate packets forwarded from multiple splitters. NPB eliminates duplication to prevent tools from wasting processing power while processing redundant data.   SSL decryption Secure Socket Layer (SSL) encryption is a standard technology used to securely send private information. However, hackers can also hide malicious cyber threats in encrypted packets.   Examining this data must be decrypted, but breaking down the code requires valuable processing power. Leading network packet brokers can offload decryption from security tools to ensure overall visibility while reducing the burden on high-cost resources. Data desensitization   SSL decryption makes the data visible to anyone with access to security and monitoring tools. The NPB can block credit card or Social Security numbers, protected health information (PHI), or other sensitive personally identifiable information (PII) before passing on information, so that information is not disclosed to the tool and its administrators.   Header stripping NPB can remove VLAN, VXLAN, L3VPN headers, etc., so tools that cannot handle these protocols can still receive and process packet data. Context-aware visibility helps detect malicious applications running on the network and the footprints left by attackers as they work their way through the system and network.   Application and threat intelligence Early detection of vulnerabilities can reduce the loss of sensitive information and the ultimate cost of vulnerabilities. The context-aware visibility provided by NPB can be used to expose intrusion indicators (IOCS), identify the geographic location of attack vectors, and combat cryptographic threats.   Application intelligence extends beyond Layers 2 through 4 of the packet data (OSI model) up to layer 7 (application layer). Rich data about user and app behavior and location can be created and exported to prevent application-layer attacks where malicious code masquerades as normal data and valid client requests.   Context-aware visibility helps spot malicious applications running on your network and the footprints left by attackers as they work their way through systems and networks.   Application monitoring The visibility of application perception also has a profound impact on performance and management. Perhaps you're wondering when an employee used a cloud-based service like Dropbox or Web-based email to bypass security policies and transfer company files, or when a former employee tried to access files using a cloud-based personal storage service.   Benefits of NPB for you - Easy to use and manage - The intelligence that removes the burden on the team - No packet loss - 100% reliability when running advanced features - High-performance architecture

Where Does Cyber Security Differ? Cyber security is much more concerned with threats from outside the castle. Where network security is worried about what is going on within the castle walls, cyber security is watching who is trying to pass through the gate or breach the parapets. The two areas have a lot of overlap, but their areas of concern are quite different. The cyber security specialist is the crusading knight defending the kingdom. Cyber security focuses on the barbarians at the gate and how the castle connects to the world around it.   Network protection - detecting and protecting against outside attempts to get into the network   Up-to-date information - staying informed on how attackers and hackers are improving their efforts Intelligence - identifying the sources of outside attacks and protecting against them Applications - monitoring the use of applications to avoid unintended breaches from within   Cyber security: Mainly to deal with external threats, network securty is mainly to deal with internal network security, cybersecurty is mainly to monitor who wants to climb over our walls, or in our inadequate care of the place to punch a hole in. There is overlap between the two jobs, but cyber securiy is more like the Crusader knights defending the king and the barbarians guarding the gate People, and they also have to think about how the castle connects to the outside. Main work content: 1. Network Protection - Monitoring and protecting bad actors from outside who are trying to illegally enter our internal network 2. Update - Keep track of what the hackers are up to and how they're doing it 3. Intelligence - Identify external sources of attack and reject them 4. Apps - Monitor your app for allegations and avoid unexpected violations from within       What is Network Security? If the field of internet security is attractive to you, you need to know the important distinction between network security and cyber security. If you think of a company as castle fortified against outside threats, network security is concerned about maintaining peace and calm within the walls of the castle. It focuses on maintaining the fortifications, of course, but its primary purpose is to guard against problems from within. A person concerned with network security will be focusing on protecting a company's internal information by monitoring employee and network behavior in several ways. They are the shire reeve responsible for keeping peace in the land.   IDs and passwords - making certain they are effective and updated frequently   Firewalls - keeping outside threats at bay Internet access - monitoring the sites employees visit on the company's computers Encryption - making certain that company information is useless to anyone outside the company Backups - scheduling regular backups of company information in case of a hardware malfunction or successful outside threat Scans - conducting regular virus and malware scans to detect any outside infection   Network Security It mainly corresponds to the internal use of the network, which is mainly used to manage the network behavior in the company, monitor the important information inside the company, and the online behavior of employees. Main work content: 1. User |D and password - Make sure they are changed regularly and updated regularly 2. Firewall - Set up security policies and monitor traffic 3.internet Access - Monitor employees accessing websites within the company 4. Encryption - Encrypt the computers of important employees and important company documents to prevent artificial transmission 5. Backup - Develop and follow company backup policy 6. Scan - Periodically scan for server vulnerabilities and monitor client viruses 7. Server Connection Monitoring - Regularly monitor server logs and abnormal connections (personal increase)8. Network security training - Regular security training for employees (personal increase)

Netflow (Network Data Flow Detection Protocol) With the software system upgrade and the maturity of the vulnerability repair scheme, the virus attack mode that directly invades the host for damage is gradually reduced, and then turns to malicious consumption of limited network resources, causing network congestion, thus destroying the ability of the system to provide external services. In response to such attacks, the industry has proposed a method of detecting network data Flow to judge network anomalies and attacks. By detecting network data flow information in real time, network managers can check the status of the whole network in real time by matching the historical pattern (to judge whether it is normal) or the abnormal pattern (to judge whether it is attacked). Detect possible bottlenecks in network performance, and automatically handle or alarm display to ensure efficient and reliable network operation. Netflow technology was first invented by Darren Kerr and Barry Bruins of Cisco in 1996 and registered as a US patent in May of the same year. Netflow technology is first used in network equipment to accelerate data exchange, and can realize the measurement and statistics of high-speed forwarded IP data flow. After years of technological evolution, the original function of Netflow for data exchange acceleration has been gradually replaced by dedicated ASIC chips in network devices, while the function of measuring and statistics of IP data flow through network devices is still retained. It has become the most recognized industry standard for IP/MPLS traffic analysis, statistics and billing in the Internet field. Netflow technology can analyze and measure the detailed behavior pattern of IP/MPLS network traffic, and provide detailed statistics of network operation. The Netflow system consists of three main parts: the Exporter, the Collector, and the Analysis reporting system. Exporter: monitors network data Collector: Used to collect network data exported from Exporter Analysis: Used to analyze the network data collected from the Collector and generate reports   By analyzing the information collected by Netflow, network administrators can know the source, destination, network service type of packets, and the cause of network congestion. It may not provide a complete record of network traffic like tcpdump does, but when put together it is much easier to manage and read. NetFlow network data output from routers and switches consists of expired data flows and detailed traffic statistics. These data flows contain the IP address associated with the source and destination of the packet, as well as the Protocol and Port used by the end-to-end session. The traffic statistics include the data flow timestamp, source and destination IP addresses, source and destination port numbers, input and output interface numbers, next hop IP addresses, total bytes in the flow, number of packets in the flow, and time stamps of the first and last packets in the flow. And front mask, packet number, etc. Netflow V9 is a new flexible and extensible Netflow data output format with template-based statistics output. Easy to add data fields that need to be output and support a variety of new functions, such as: Multicase Netflow, MPLS Aware Netflow, BGP Next Hop V9, Netflow for IPv6, and so on. In 2003, Netflow V9 was also selected as the IPFIX (IP Flow Information Export) standard by the IETF from five candidates.   IPFIX (Network Traffic Monitoring) Flow-based technology is widely used in network field, it has great value in QoS policy setting, application deployment and capacity planning. However, network administrators lack a standard format for output data streams. IPFIX (IP Flow Information Export, IP data flow information output) is a standard protocol for measuring flow information in networks published by IETF. The format defined by IPFIX is based on the Cisco Netflow V9 data output format, which standardizes the statistics and output standards of IP data flows. It is a protocol for analyzing data flow characteristics and output data in a template-based format. Therefore, it has strong scalability. If traffic monitoring requirements change, network administrators can modify the corresponding configurations without upgrading network device software or management tools. Network administrators can easily extract and view important traffic statistics stored in these network devices. For a more complete output, IPFIX uses seven key domains of network devices by default to represent network traffic per share: 1. Source IP address 2. Destination IP address 3. TCP/UDP source port 4. TCP/UDP destination port 5. Layer 3 protocol type 6. The Type of service (Type of service) byte 7. Enter a logical interface If all seven key domains in different IP packets match, the IP packets are regarded as belonging to the same traffic. By recording the characteristics of the traffic on the network, such as the traffic duration and average packet length, you can learn about the current network application, optimize the network, detect the security, and charge the traffic.   IPFIX networking architecture To sum up, IPFIX is based on the concept of Flow. A Flow refers to packets from the same subinterface with the same source and destination IP address, protocol type, source and destination port number, and ToS. The packets are usually 5-tuples. IPFIX records statistics about the stream, including the timestamp, the number of packets, and the total number of bytes. IPFIX consists of three devices: Exporter, Collector, and Analyzer. The relationships among the three devices are as follows: Export analyzes network flows, extracts qualified flow statistics, and sends the statistics to Collector. The Collector parses Export data packets and collects statistics in the database for analysis by the Analyser. The Analyser extracts statistics from the Collector, performs subsequent processing, and displays the statistics as a GUI for various services.   IPFIX application scenarios Usage-based Accounting Traffic billing in network operators is generally based on the upload and download traffic of each user. Because IPFIX can be accurate to the destination IP address, protocol port and other fields, the future traffic charging can be segmented based on the characteristics of the application service. Of course, the protocol also explains that IPFIX packet statistics are "sampled". In many applications (such as the backbone layer), the more detailed the data flow statistics are, the better. Due to the performance of network devices, the sampling rate cannot be too small, so it is not necessary to provide completely accurate and reliable traffic billing. However, at the network operator level, the billing unit is generally more than 100 megabits, and the sampling accuracy of IPFIX can meet the relevant needs. Traffic Profiling, Traffic Engineering The record output of IPFIX Exporter, IPFIX Collector can output very rich Traffic record information in the form of various charts, this is the concept of Traffic Profiling. However, just the record of information, can not take advantage of the powerful function of IPFIX, IETF also launched the concept of Traffic Engineering: in the actual operation of the network, often planned load balancing and redundant backup, but the various protocols are generally according to the predetermined route of the network planning, or protocol principles are adjusted. If IPFIX is used to monitor the traffic on the network and a large amount of data is found in a certain period of time, the network administrator can be reported to adjust the traffic, so that more network bandwidth can be allocated to related applications to reduce the uneven load. In addition, you can bind configuration rules, such as route adjustment, bandwidth allocation, and security policies, to the operations on the IPFIX Collector to automatically adjust network traffic. Attack/Intrusion Detection Attack/Intrusion detection IPFIX can detect network attacks based on traffic characteristics. For example, typical IP scanning, port scanning, DDOS attacks. The sampling standard IPFIX protocol can also use a "signature database" upgrade to block the latest network attacks, just like the general host-side virus protection. QoS Monitoring (Network Quality of Service Monitoring) Typical QoS parameters are: Packet loss condition: loss [RFC2680] one-way delay: One-way delay [RFC2679] round-trip delay: round-trip delay [RFC2681] delay variation [RFC3393] Previous technologies are difficult to monitor the above information in real time, but IPFIX's various custom fields and monitoring intervals can easily monitor the above values of various messages.   Here's an expanded table that provides more details about the differences between NetFlow and IPFIX:
