Description: Cybersecurity management is the process of managing and protecting an organization’s information systems against cyber threats. Within this scope, Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) play a crucial role. An IDS is a tool that monitors network traffic and system activities for suspicious behavior or policy violations. On the other hand, an IPS not only detects these threats but also takes measures to prevent them by blocking malicious traffic in real-time. Both systems are essential for defense in depth, providing an additional layer of security that complements other protective measures. Effective implementation of IDS/IPS allows organizations to quickly identify and respond to security incidents, minimizing the impact of potential breaches. Additionally, these systems generate reports and alerts that are fundamental for forensic analysis and the continuous improvement of security policies. In an increasingly complex and threatening digital environment, cybersecurity management, particularly the use of IDS/IPS, has become a strategic priority for companies seeking to protect their most valuable assets.
History: Intrusion Detection Systems (IDS) emerged in the 1980s in response to the growing need to protect computer networks. The first IDS, known as the ‘Intrusion Detection Expert System’ (IDES), was developed by the United States Department of Defense in 1984. As cyber threats evolved, so did IDS, incorporating more advanced techniques such as behavioral analysis and artificial intelligence. In the 1990s, Intrusion Prevention Systems (IPS) began to appear, offering not only threat detection but also the ability to block attacks in real-time. This evolution has been driven by the increase in Internet connectivity and the sophistication of cyber attacks.
Uses: IDS/IPS systems are primarily used in various environments to protect critical networks and systems. They are implemented across multiple industries, including finance, healthcare, and telecommunications, where data security is paramount. These systems enable organizations to detect and respond to intrusions, as well as comply with security and auditing regulations. Additionally, they are key tools in security incident management, providing valuable information for threat investigation and analysis.
Examples: An example of an IDS is Snort, which is widely used for its real-time detection capabilities and flexibility. As for IPS, an example is Cisco Firepower, which combines detection and prevention capabilities with advanced threat analysis. Both systems have been used in real security incidents, where they have helped mitigate attacks and protect data integrity.
