Providing a quick and effective reporting system when anomalous or malicious activity occurs, which enables the threat to be passed up the stack.

Providing an extensive database of attack signatures that can be used to match and detect known threats.Providing an easy-to-use interface that allows staff who are not security experts to help with the management of an organization’s systems.

Enabling system administrators to organize and understand their relevant operating system audit trails and logs that are often difficult to manage and track.

Monitoring the performance of key firewalls, files, routers, and servers to detect, prevent, and recover from cyberattacks.

IDS solutions do this through several capabilities, including: This enables organizations to detect the potential signs of an attack beginning or being carried out by an attacker. It then alerts or reports these anomalies and potentially malicious actions to administrators so they can be examined at the application and protocol layers. They are placed at strategic locations across a network or on devices themselves to analyze network traffic and recognize signs of a potential attack.Īn IDS works by looking for the signature of known attack types or detecting activity that deviates from a prescribed normal. IDS solutions excel in monitoring network traffic and detecting anomalous activity. This approach enables the IDS to watch packets as they move through the organization’s network and pulls malicious packets before applications or the operating system can process them.

Stack-based intrusion detection system (SBIDS): SBIDS is integrated into an organization’s Transmission Control Protocol/Internet Protocol (TCP/IP), which is used as a communications protocol on private networks.

It enables organizations to monitor traffic across all the devices and systems that their devices are connected to.

Virtual machine-based intrusion detection system (VMIDS): A VMIDS solution detects intrusions by monitoring virtual machines.

Perimeter intrusion detection system (PIDS): A PIDS solution is placed on a network to detect intrusion attempts taking place on the perimeter of organizations’ critical infrastructures.

This ensures businesses can discover new, evolving threats that solutions like SIDS cannot. An AIDS solution uses machine-learning techniques to build a baseline of normal behavior and establish a corresponding security policy.

Anomaly-based intrusion detection system (AIDS): This solution monitors traffic on a network and compares it with a predefined baseline that is considered 'normal.' It detects anomalous activity and behavior across the network, including bandwidth, devices, ports, and protocols.

Signature-based intrusion detection system (SIDS): A SIDS solution monitors all packets on an organization’s network and compares them with attack signatures on a database of known threats.

It can also discover malicious threats coming from the host, such as a host being infected with malware attempting to spread it across the organization’s system. This solution can detect packets that come from inside the business and additional malicious traffic that a NIDS solution cannot.

Host intrusion detection system (HIDS): A HIDS system is installed on individual devices that are connected to the internet and an organization’s internal network.

This IDS approach monitors and detects malicious and suspicious traffic coming to and going from all devices connected to the network.

Network intrusion detection system (NIDS): A NIDS solution is deployed at strategic points within an organization’s network to monitor incoming and outgoing traffic.

Common types of intrusion detection systems (IDS) include: IDS solutions come in a range of different types and varying capabilities.
