Increasing network security threats and destructive network attacks bring serious losses to enterprises. Simple firewalls cannot prevent complex and changeable attacks. You are advised to deploy IDS (intrusion detection system) and other security devices to protect enterprise networks. IDS protects suspicious behaviors on the network or operating system, makes policy responses, cuts off the source of intrusion in time, records and notifies network administrators through various channels, and ensures system security to the maximum extent.

Apsara Clouder Cloud Security Special skills certification: Build intrusion detection system

(This certification course can help students to understand the role, function, classification, technical principle of IDS (Intrusion Detection system) and open source intrusion detection and commercial intrusion detection products, master the deployment mode of intrusion detection system, through the powerful Snort as an example to build IDS, understand the preparation and installation of Snort environment. Familiar with Snort configuration and precautions in the configuration process, understand and operate Snort configuration of three modes, and finally verify IDS through simulated hacker attack)


Now network administrators expect intrusion detection systems (IDS) and intrusion Prevention systems (IPS) to also detect web application attacks, including sensing anomalies. This article will help you understand IDS and IPS, and how to integrate them for perfect protection.
The hardest part about choosing an IDS or IPS is knowing when you need it and what it does. With all the firewalls on the market, application firewalls, unified threat management devices, IDS and IPS, it’s hard to differentiate between the functions of these products and know which ones are best for certain functions. Some enterprises deploy IPS and find that they can remove the original IDS, and you may be considering whether to replace IDS with IPS. But it’s not for everyone.
Application programs are increasingly becoming the gateway of attack threats. For example, e-commerce applications are very vulnerable to attack. Unfortunately, traditional IDS and IPS do not protect the enterprise from such attacks. Fortunately, vendors now have application-oriented IDS and IPS, for example, Web application firewalls, which detect frequent attack techniques through exceptions and tagging techniques. The new IPS could make up for the shortcomings of traditional systems.
Installing and configuring network intrusion prevention Installing and configuring intrusion prevention devices based on exceptions is more complex than token-based devices. Exception-based devices detect and prevent zero-day attacks by detecting abnormal network activity. Installing and configuring a system that recognizes unknown activities requires knowledge of expected activities. But it’s not enough to monitor the network for just a few hours. To avoid false positives, the system must identify different activities that occur during the day and during the month.
Unlike other security devices, IDS/IPS need to be maintained and adjusted after installation and configuration. The algorithms of IDS and IPS are completely different, so it is necessary to adjust in time to reduce false positives and missed positives.
If you’ve ever been in a situation where companies have to integrate multiple defense systems while also being constrained by data center and energy costs, you might want to unify network infrastructure security policies. Vendors will adjust their offerings from putting multi-vendor software on open racks to integrating network infrastructure security policies that can reduce administrative and energy expenses by reducing physical security equipment in data centers.
