Which intrusion detection system contains information about specific attacks and system vulnerabilities?
UC Berkeley security policy mandates compliance with Minimum Security Standard for Electronic Information for devices handling covered data. The recommendations below are provided as optional guidance to meet continuous vulnerability assessment and
remediation requirements. Resource Custodians must continuously monitor for signs of attack and compromise on all covered devices. Attackers can discover and compromise covered data on devices that are not secured against vulnerabilities. Intrusion Detection Systems (IDS) are automated
systems that monitor and analyze network traffic and generate "alerts" in response to activity that either match known patterns of malicious activities or is unusual. In some cases, alerts trigger further automated processes such as recording the suspect activity and/or scanning the computer(s) involved for signs of compromise. IDS allows resource proprietors and custodians to respond timely to covered devices that are compromised or imminently in danger of being compromised. IDS can be either network or host-based. A network-based IDS monitors network traffic for particular network segments or devices and analyzes network, transport, and application protocols to identify suspicious activity. A host-based IDS (HIDS) monitors the characteristics of a single host and the events occurring within that host for suspicious activity. For more discussion on HIDS, please see the relevant section in Additional Resources. The Information Security Office (ISO) provides a centralized, MSSEI compliant, network-based intrusion detection program that monitors systems on the campus network. By registering as directed in MSSEI “Annual Registration” requirement, covered devices are enrolled in additional monitoring services. ISO alerts from the IDS program on covered devices should be responded to in a timely fashion, as defined in your system’s Incident Response Plan (see MSSEI 16). Off-campus NetworksIn cases where covered devices are hosted outside of campus networks, such as collaborating research labs and agencies, ensure non-campus networks also maintain equivalent intrusion detection controls that follow the recommended practices below:
Additional ResourcesSecuring IDSSecuring IDS components is very important because IDSs are often targeted by attackers who want to prevent the IDSs from detecting attacks or want to gain access to sensitive information in the IDSs, such as host configurations and known vulnerabilities. IDSs are composed of several types of components, including sensors or agents, management servers, database servers, user and administrator consoles, and management networks. All components’ operating systems and applications should be kept fully up-to-date, and all software-based IDS components should be hardened against threats. Specific protective actions of particular importance include
Administrators should maintain the security of the IDS components on an ongoing basis, including verifying that the components are functioning as desired, monitoring the components for security issues, performing regular vulnerability assessments, responding appropriately to vulnerabilities in the IDS components, and testing and deploying IDS updates.

HIDS can provide additional detection is by installing agents on monitored systems. A central management server typically controls the agent software over the network, which maintains agent configuration as defined by the HIDS administrator and collects events from the agent software. From the collected events, the central HIDS server is able to correlate activities from all of its monitored hosts based on predefined signatures and customized rules to produce alerts on suspicious or malicious behaviors. The collected events can also be sent to log correlation software (e.g. ISO Log Correlation program) for further analysis. Some of the additional detection capabilities include:

What are the types of intrusion detection system?IDS are classified into 5 types:. Network Intrusion Detection System (NIDS): ... . Host Intrusion Detection System (HIDS): ... . Protocol-based Intrusion Detection System (PIDS): ... . Application Protocol-based Intrusion Detection System (APIDS): ... . Hybrid Intrusion Detection System :. What are the two types of intrusion detection system in information security?There are two main types of IDSes based on where the security team sets them up: Network intrusion detection system (NIDS). Host intrusion detection system (HIDS).
What is intrusion detection system in information security?An Intrusion Detection System (IDS) is a monitoring system that detects suspicious activities and generates alerts when they are detected. Based upon these alerts, a security operations center (SOC) analyst or incident responder can investigate the issue and take the appropriate actions to remediate the threat.
