Day 21 of #100daysofcybersecuritychallenges: An Intrusion Detection System (IDS) is a security tool that monitors computer networks or systems for malicious activities or policy violations Monitoring and Analysis: IDS continuously monitors network traffic or system activities, analyzing packets, logs, and events in real-time or near-real-time. How IDS Works: Traffic Monitoring: The IDS continuously monitors network traffic, including incoming and outgoing data packets. Signature-Based Detection: One common detection method involves comparing traffic patterns against a database of known attack signatures. Anomaly-Based Detection: Another approach focuses on identifying unusual patterns in network traffic that deviate from normal activity. Alert Generation: If the IDS detects suspicious activity, it generates an alert, notifying security personnel or taking pre-configured actions to contain the threat. Benefits of Using an IDS: Enhanced Threat Detection: IDS can identify a wider range of threats compared to firewalls, which primarily focus on blocking pre-defined malicious traffic. Real-Time Monitoring: Continuous monitoring allows for early detection of potential intrusions, giving security teams time to react and mitigate the damage. Improved Security Posture: By proactively identifying and addressing threats, IDS helps to strengthen your overall network security posture. Types of IDS: Network Intrusion Detection System (NIDS): Monitors network traffic for suspicious activity at strategic points within the network. Host-Based Intrusion Detection System (HIDS): Installed on individual devices (servers, desktops) to monitor system activity and file changes for signs of intrusion attempts. #network #cybersecurity #ComputerNetwork #100daysofcybersecurity #100daysofselflearning #ethical #hacking #networkingbasics #staysecure

Cybersecurity Terminologies of the Day: IR (Incident Response), IPS (Intrusion Prevention System), and IDS (Intrusion Detection System). Today, let's explore three essential components of our cybersecurity toolkit: IRP(Incident Response Plan), IPS (Intrusion Prevention System), and IDS (Intrusion Detection System). 1. Incident Response Plan (IRP): IRP serves as our strategic blueprint plan when cyber threats knocking. It's the strategy we employ to identify, manage, and mitigate the impact of security incidents. Think of it as our playbook for dealing with breaches, data leaks, and other malicious activities. 2. Intrusion Prevention System (IPS): IPS is like the vigilant gatekeeper of our digital fortress. It's designed to proactively identify and block potentially harmful traffic before it can infiltrate our network. IPS is our first line of defense, actively keeping intruders at bay and ensuring that only safe data enters. 3. Intrusion Detection System (IDS): IDS, on the other hand, is our watchful sentry. It constantly scans our network for signs of suspicious or malicious activity. When it spots something amiss, it raises the alarm. IDS doesn't block traffic but acts as our early warning system, alerting us to potential threats so we can take swift action. Always remember, that our greatest assets against cyber threats lie in continuous learning and collaborative efforts. #CyberSecurity #IncidentResponse #IPS #IDS #StaySecure
