Every day, new techniques to compromise computing environments are created, and it is a great challenge for the information security market to keep up with this speed, and even be ahead so as not to act reactively. For this reason, the implementation of a good IDS policy is fundamental in a security architecture, since this feature, if constantly updated, is able to keep the infrastructure away from opportunistic attacks, either from a network perspective, or by compromising a computer itself.
Combining both network-based and host-based intrusion prevention and detection systems is critical to good safety health. None of the models presented is necessarily exclusive; on the contrary, they should be treated as complementary according to the need and criticality of protection demanded by a business.
Are you already using IDS to detect anomalous and unwanted situations in computer systems and networks?
The network intrusion detection and prevention system (IDPS) appliance market is composed of stand-alone physical and virtual appliances that inspect defined network traffic either on-premises or in the cloud.
They are often located in the network to inspect traffic that has passed through perimeter security devices, such as firewalls, secure Web gateways and secure email gateways.
IDPS devices are deployed 'in-line' and perform full-stream reassembly of network traffic.
They provide detection via several methods — for example, signatures, protocol anomaly detection, behavioral monitoring or heuristics, advanced threat defense (ATD) integration, and threat intelligence (TI).
When deployed in-line, they can also use various techniques to detect and block attacks that are identified with high confidence; this is one of the primary benefits of this technology.
Next-generation IDPSs have evolved in response to advanced targeted threats that can evade first-generation IDPSs.
