Cyber Security Fundamentals

Study Notes

Types of Cyber Threats

Malware: Software designed to harm or exploit computer systems, including viruses, worms, and Trojan horses.
Phishing: Fraudulent emails, texts, or messages that trick users into revealing sensitive information.
Ransomware: Malware that encrypts files and demands payment in exchange for decryption.
Denial of Service (DoS) and Distributed Denial of Service (DDoS): Attacks that overwhelm systems with traffic, making them unavailable.
SQL Injection: Injecting malicious code into databases to access or manipulate sensitive data.
Cross-Site Scripting (XSS): Injecting malicious code into websites to steal user data or take control of user sessions.

Cyber Security Measures

Firewalls: Network security systems that monitor and control incoming and outgoing traffic.
Encryption: Protecting data by converting it into a code that can only be deciphered with a decryption key or password.
Strong Authentication: Verifying user identities through passwords, biometrics, or two-factor authentication.
Regular Software Updates: Keeping software and systems up-to-date to patch vulnerabilities and fix security flaws.
Network Segmentation: Dividing networks into smaller, isolated segments to limit the spread of attacks.
Incident Response: Plans and procedures for responding to and managing cyber security incidents.

Cyber Security Best Practices

Use Strong Passwords: Use unique, complex passwords and avoid using the same password across multiple sites.
Keep Software Up-to-Date: Regularly update operating systems, browsers, and software to ensure you have the latest security patches.
Be Cautious with Email Attachments: Avoid opening suspicious email attachments or clicking on links from unknown senders.
Use Two-Factor Authentication: Add an extra layer of security to your accounts by requiring a second form of verification, such as a code sent to your phone.
Back Up Data: Regularly back up important data to prevent loss in the event of a cyber attack.

Cyber Security Careers

Security Analyst: Monitor and analyze network traffic to identify and respond to security threats.
Penetration Tester: Simulate cyber attacks to test an organization's defenses and identify vulnerabilities.
Chief Information Security Officer (CISO): Oversee and implement an organization's cyber security strategy.
Incident Responder: Respond to and manage cyber security incidents, including containment, eradication, and recovery.
Cyber Security Consultant: Provide expert advice and guidance on cyber security best practices and risk management.
