充分发挥网络的强大潜能

Read this solution brief to see how you can use a network packet broker (NPB) to direct SSL-based traffic to a purpose-built decryption device to eliminate the issue.

This solution brief shows a powerful way to improve your network security defenses. Learn how you can automate the security threat alert inspection process. Network packet brokers help this process by allowing IT to serially chain multiple security tools (IDS, DLP, SIEMs, firewalls, etc.) together to inspect network data for security threats.

This solution brief provides an easy way to validate if security patches have been applied and are working to prevent costly damages from network security attacks.

The challenge for IT security and operations professionals is how to balance the need for data protection and security.

This solution brief provides a general overview of how application intelligence can improve network and application troubleshooting and monitoring functions. In addition, a clear example is provided to illustrate how IT can change the focus of troubleshooting from reactive efforts to proactive efforts to help reduce time and cost.

A network visibility architecture can be deployed to allow IT to install solutions that access, aggregate, refine, and distribute critical troubleshooting data. This data can then be used to isolate and identify network problems as quickly as possible to restore optimal functionality.

A key component to reducing the mean time to repair (MTTR) is to choose a network packet broker (NPB) that allows you to create predefined filters, also called floating filters. Once a floating filter is created, it can be applied at will, which can save you several minutes (to more than an hour) of troubleshooting time per occurrence.

To maintain security and optimize performance in the cloud, your monitoring systems need access to all of your cloud-based data traffic. What you need is a reliable and scalable way to get visibility to cloud-based traffic, pinpoint data that is relevant, and deliver it quickly to your monitoring systems, no matter where they are located. Ixia's cloud visibility platform offers key advantages that other solutions do not.

The first building-block to your visibility architecture is access to the data. That comes in one of two forms: a network tap or a switch port analyzer (SPAN) port (also known as port mirroring). But which is the right one? This document should help answer that question. These days, your network is as important to your business as any other item—including your products.

Cisco has created a software defined networking (SDN) solution called Application Centric Infrastructure (ACI). To optimize this solution for monitoring purposes, a Visibility Architecture consisting of taps and network packet brokers (NPBs) is needed. The Visibility Architecture is used to overcome the inherent limitations of an ACI architecture and maximize the use of your Cisco equipment. Read this document to learn how to: First, improve ACI deployments with packet filtering, header striping, and packet slicing. Second, reduce monitoring data bandwidth by applying de-duplication. Third, eliminate encapsulation issues by using an NPB to strip off VXLAN headers.

In regards to network visibility, it's not just about using the right monitoring tool for the right job. Delivering the right information to the right tool, is even more important. Application information is critical to network visibility and monitoring efforts. This includes the ability to remove blind spots, see indicators of compromise, and maximize troubleshooting efforts to improve your network mean time to repair. Read this whitepaper to see how you can: filter data based upon specific applications, spot indicators of compromise, improve your security tool (DLP, IDS, etc.) analysis, and improve your troubleshooting efforts.

Supporting lawful data intercept requests is becoming increasingly important for service providers. At the same time, it has also become a new challenge for enterprises. The world’s nations are writing laws legally mandating access to communications, and expanding access to all types of user information including voice, video, data, and even location information. It does not stop there as the requirements and legal application of laws vary by country, and even by state. This paper provides a basic overview of lawful data intercept, as well as some recommendations for best practices to help you meet basic compliance for several of the mandated lawful intercept scenarios.

General Data Protection Regulation (GDPR) will go into effect on May 25, 2018 and impact all organizations that conduct business in the European Union (EU), offer goods or services to residents of the EU, or monitor the online behavior of EU residents. GDPR is a multi-faceted regulation and no single solution will ensure compliance, but strengthening network security and preventing data loss is key. Keysight is working with customers around the globe to help them increase their visibility to the information crossing their network, so they are better prepared for the upcoming changes. This FAQ document provides key information on GDPR for those making decisions about network and application security.

The Market in Financial Instruments Directive version II (MiFID II) expanded the European Union's financial regulation and took effect in January 2018. Ixia visibility solutions, including TradeVision, help capital market participants meet their MiFID II obligations by rapidly identifying and fixing trading traffic problems.
