In response to your peers, apply a systems-thinking approach and provide recommendations on resolving the issue or reducing the impact of false positives or negatives from an IDS/IPS. To complete this assignment, review the Discussion Rubric. For your response posts, do the following: • Reply to at least two classmates outside of your own initial post thread. . In Module One, complete your two response posts by • In Modules Two through Eight, complete your two response posts Demonstrate more depth and thought than saying things like “I agree” or “You are wrong.” Guidance is provided for you in the discussion prompt.

Both of these systems log detailed information about the traffic and patterns they Total deliver, including IP addresses (both source and destination), timestamps, protocol details, and payload snippets. This data is invaluable in understanding the traffic flow and identifying anomalies and patterns that may indicate a compromise or attack. Using a threat intelligence feed that includes up-to-date information on IP addresses, file hashes, and URLs associated with malicious activities can enrich the data already being analyzed by an IDS/IPS significantly. The correlation of incoming network traffic to known malicious indicators provided can help the IDS/IPS identify and respond to threats more efficiently, faster, and with more accuracy. Proactive approaches like this help security teams to prioritize their responses better and adapt their defensive strategies based on real-time global threat data. Response Two 8-1 Discussion Karl Reddick Hello class and congrats on making it to week 8! We made it! Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) are crucial technologies that help organizations gather data about activities within their network. IDS monitors network traffic for suspicious activity or security policy violations, while IPS actively blocks or prevents attempted intrusions. One example of a threat intelligence source is the Open Source Intelligence (OSINT) feeds, which provide information on known malicious IP addresses, domains, or signatures. By leveraging OSINT feeds, organizations can stay updated on the latest threats and indicators of compromise. When correlating data from an operational IDS/IPS with threat intelligence sources like OSINT feeds, organizations can enhance their security posture in the following ways: 1. Identifying Known Threats: IDS/IPS alerts can be compared with threat intelligence sources to check for matches with known malicious indicators. This correlation helps in quickly identifying and responding to threats based on established patterns. 2. Behavioral Analysis: By analyzing the network traffic patterns detected by IDS/IPS in conjunction with threat intelligence, organizations can uncover anomalous behavior that may indicate a new or evolving threat. 3. Enhanced Response: Correlating IDS/IPS data with threat intelligence allows security teams to prioritize and respond to threats effectively. It helps in focusing on the most critical alerts that pose a significant risk to the network. 4. Threat Hunting: Security analysts can proactively search for indicators from threat intelligence feeds within their network data collected by IDS/IPS to uncover potential threats that may not have been detected initially. By integrating threat intelligence sources with IDS/IPS data, organizations can create a more robust security defense mechanism that is proactive, informed, and capable of identifying and mitigating threats in real-time.
