 To protect against zero-day vulnerabilities, here are some effective techniques: Regular Patching and Updates : Ensure that all software, operating systems, and applications are regularly updated with the latest patches and security updates. Vendors often release patches to address known vulnerabilities, including zero-day exploits. Intrusion Detection/Prevention Systems (IDS/IPS) : Deploy IDS/IPS solutions that can monitor network traffic and identify suspicious activities or behavior that may indicate a zero-day exploit. These systems can help detect and block attacks before they can cause harm. Network Segmentation : Implement network segmentation to isolate critical systems and sensitive data from the rest of the network. By separating network resources, even if a zero-day vulnerability is exploited, the attacker's access and impact can be limited. Application Whitelisting : Implement application whitelisting, which allows only approved and trusted software to run on systems. ...

 Intrusion detection and prevention systems (IDS/IPS) concepts. Intrusion Detection Systems (IDS) : IDS are like the "guard dogs" of a computer network. They monitor network traffic, searching for any suspicious or malicious activity. When they detect something fishy, they raise an alarm to alert the administrators. IDS can use various detection methods, such as signature-based detection (matching known attack patterns) or anomaly-based detection (identifying deviations from normal network behavior). Intrusion Prevention Systems (IPS) : IPS can be thought of as the "bouncers" of a network. They not only detect intrusions but also take action to prevent them. When an IPS identifies a potential attack, it can actively block the suspicious traffic, drop malicious packets, or modify network configurations to stop the attack in its tracks. Honey Pots : Imagine a honeypot as a "decoy" system, deliberately designed to attract attackers. It mimics vulnerable or va...
