Security threat: Any potential danger to your digital assets, including viruses, malware, phishing attacks, and more.
Vulnerability: A weakness in your system or software that can be exploited by hackers.
Risk management: The process of identifying, assessing, and mitigating potential security threats.

Types of Cybersecurity Threats

Cybersecurity threats come in various forms, including:

Malware: Software designed to harm or exploit your system, such as viruses, Trojans, and ransomware.
Phishing: Social engineering attacks that trick you into revealing sensitive information.
Denial of Service (DoS) attacks: Overwhelming your system with traffic to make it unavailable.
SQL injection: Injecting malicious code into databases to extract or manipulate data.

Cybersecurity Best Practices
