Integrate incident response procedures to investigate and escalate confirmed incidents detected by IDS.Develop processes to send suspicious activities alerts to the appropriate resource custodians and proprietors.Capture at least packet headers of traffic and retain for at least 7 days, to be used as forensic data in case of a possible compromise.Schedule automated regular updates to detection signatures such that new and emerging threats can be detected.See Additional Resources section for additional guidance. See Additional Resources for examples of common IDS tools. Use industry-standard network intrusion detection system (IDS) tools to analyze signatures and network behavior for signs of attack or compromise.In 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:

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). By registering as directed in MSSEI “Annual Registration” requirement, covered devices are enrolled in additional monitoring services.
The Information Security Office (ISO) provides a centralized, MSSEI compliant, network-based intrusion detection program that monitors systems on the campus network. For more discussion on HIDS, please see the relevant section in Additional Resources. A host-based IDS (HIDS) monitors the characteristics of a single host and the events occurring within that host for suspicious activity. A network-based IDS monitors network traffic for particular network segments or devices and analyzes network, transport, and application protocols to identify suspicious activity. IDS allows resource proprietors and custodians to respond timely to covered devices that are compromised or imminently in danger of being compromised. 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. 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. Description of RiskĪttackers can discover and compromise covered data on devices that are not secured against vulnerabilities. Resource Custodians must continuously monitor for signs of attack and compromise on all covered devices. The recommendations below are provided as optional guidance to meet continuous vulnerability assessment and remediation requirements. UC Berkeley security policy mandates compliance with Minimum Security Standard for Electronic Information for devices handling covered data.
