NIDS (Network Intrusion Detection Systems) are strategically placed in your network (e.g., routers, switches) to monitor traffic. They detect attacks like DoS attacks or exploits targeting network vulnerabilities. NIDS provides a comprehensive view of network activity, helping identify anomalies or patterns indicative of breaches. Limitations include inability to inspect encrypted traffic and constraints within local area networks (LANs). Despite these, NIDS are vital for detecting and mitigating network-level threats.

Network Intrusion Detection Systems (NIDS) keep an eye on network traffic to find possible security threats. There are two types: Signature-Based, which checks for known attack patterns, and Anomaly-Based, which looks for unusual behavior compared to normal activity. NIDS inspect the content of network packets, generate alerts if something suspicious is found, and can sometimes take actions like blocking harmful traffic. They help protect networks by identifying and responding to potential threats.

Network-based IDS (NIDS) act as sentinels, offering a bird's-eye view of network activities. While strategically placed at key points in a network, they actively monitor traffic, allowing detection of attacks targeting the network as a whole. However, NIDS have limitations such as the inability to inspect encrypted traffic or traffic within a local area network (LAN). The strategic placement of NIDS provides a comprehensive overview of network traffic and potential threats. Despite limitations, NIDS offer a proactive defense against external attacks on network infrastructure. Addressing the constraints of NIDS involves integrating complementary security measures for a robust defense.

NIDS monitor network traffic in real-time, looking for patterns or signatures that may indicate malicious activity, such as known attack signatures or abnormal behavior.

NIDS offer pervasive network-wide visibility and can detect network-level attacks, but they may struggle with encrypted traffic and LAN-based activities.

HIDS is designed to monitor and analyze the activities on individual host machines. The primary purpose of HIDS is to detect and respond to security threats or potential breaches at the level of an individual computer or server. You can monitor events and activities occurring on the host itself, including file changes, log entries, system calls, and user activities. It involves monitoring critical system files and directories for any unauthorized changes or modifications. Changes to system files can be an indicator of a security breach. HIDS can employ anomaly detection techniques to identify deviations from normal behavior on a host.

Host-based IDS (HIDS) act as personalized guards for individual hosts, demanding careful consideration of resource allocation and regular updates to maintain effectiveness in safeguarding against potential intrusions. Installed on individual hosts, they monitor system files, logs, processes, and applications, identifying attacks targeting specific hosts. HIDS contribute to a proactive cybersecurity strategy by offering detailed insights into host activities. While resource-intensive, their role in verifying the integrity and compliance of individual systems is crucial. HIDS play a dynamic role as personalized defenders, necessitating frequent updates and attention to ensure their ongoing effectiveness.

NIDS provide network-wide visibility, detecting network-level threats, while HIDS monitor individual hosts, detecting host-specific attacks. Both play crucial roles in cybersecurity.

Los IDS/IPS basados en host (HIDS/HIPS) analizan el tráfico de red en busca de patrones y comportamientos anómalos, utilizan bases de datos de firmas y patrones conocidos de ataques para identificar y bloquear actividades maliciosas (exploits, malware, etc.), llevan a cabo un análisis heurístico para identificar comportamientos sospechosos, en el caso de los HIPS pueden tomar medidas proactivas para bloquear o mitigar la actividad maliciosa lo que incluye reset de conexiones, modificación de reglas de FW, reporting, etc. Además de servir como aliados a la defensa perimetral de la organización.
