Vulnerability refers to a weakness or flaw in a system, network, application, or hardware component that could be exploited by attackers to compromise the security of the system and gain unauthorized access to private data.

Vulnerabilities can exist in various forms, such as:

1. Network Vulnerabilities: Often occur due to weakness in network infrastructure, protocols, or poor configuration. Common examples include unsecured ports, misconfigured firewalls unencrypted communication channels, etc.
2. Software Vulnerabilities: They may arise due to coding errors, flaws in logic, insufficient input validations, etc.
3. Physical Vulnerabilities: These are related to weaknesses in the physical security of devices, hardware components, or infrastructure. some examples include lack of tamper resistance, susceptibility, or inadequate access controls, etc.
4. Human Vulnerabilities: These refer to weaknesses associated with human behavior, such as susceptibility to social engineering tactics, poor password practices, or lack of security awareness.

What’s a Zero Day?

Zero-day vulnerabilities are critical security flaws in software or hardware that are unknown to the vendor or developer. These…
