Cyber Security

• Cybersecurity refers to the practice of protecting systems, networks, and data from digital attacks, theft, or damage. It involves various technologies, processes, and practices designed to secure information technology infrastructure from cyber threats.

• With the rise of the internet and digital systems, businesses, governments, and individuals are increasingly at risk of cyberattacks. Cybersecurity is crucial to prevent data breaches, maintain privacy, avoid financial loss, and protect sensitive information from cybercriminals.

• • Malware: Malicious software designed to damage or gain unauthorized access to systems.
  • Phishing: Fraudulent attempts to acquire sensitive information by pretending to be a trustworthy entity.
  • Ransomware: A type of malware that locks or encrypts a victim’s data and demands a ransom for its release.
  • Denial of Service (DoS) / Distributed Denial of Service (DDoS): Attacks that overwhelm a system or network to make it unavailable to users.
  • Man-in-the-middle (MitM) Attacks: Attackers intercept communications between two parties to steal or manipulate information.
  • SQL Injection: Exploiting vulnerabilities in a website’s database by injecting malicious code.

A data breach is a security incident where sensitive, confidential, or protected information is accessed, disclosed, or stolen without authorization. This could involve personal data, payment information, or business secrets.

A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It can be hardware or software-based and is used to prevent unauthorized access, viruses, and other malicious traffic from entering or leaving a network.

Cybersecurity professionals are responsible for securing networks, systems, and data from cyber threats. This involves tasks like identifying vulnerabilities, implementing security measures, monitoring systems for potential threats, responding to security incidents, and ensuring compliance with industry regulations.
