Introduction to Cybersecurity
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business processes. The goal of cybersecurity is to defend against a wide range of threats, safeguard the integrity of networks, and ensure data privacy and availability.
Threats
Cyber threats refer to malicious attempts to damage or disrupt computer systems or networks. Common threats include malware, ransomware, phishing attacks, and denial-of-service attacks.
Cyber Attacks
Cyber attacks are deliberate actions taken by attackers to exploit vulnerabilities in systems. Examples include SQL injection, cross-site scripting (XSS), and broken authentication. These attacks target both the technology and the people behind it.
Defense Mechanisms
Defense mechanisms in cybersecurity include the implementation of firewalls, intrusion detection systems, encryption, multi-factor authentication (MFA), regular patching, and security awareness training. A layeredapproach is critical to building resilient cyber defenses.
