Cybersecurity: Protecting Against Cyber Attacks

Anne's Experience

• Anne often shops from shoppingcart.com and has her info (email, address, credit card details) saved for convenience.
• She received an email claiming eligibility for a special discount voucher, asking for her account credentials.
• The email was fake, leading to unauthorized access to her account and a substantial amount of money stolen.
• This incident is an example of a cyber attack, carried out by a hacker.

Understanding Cybersecurity

• Cybersecurity involves techniques to secure digital components, networks, data, and computer systems from unauthorized access.
• Numerous methods are employed depending on the network type and potential cyber attacks.

Types of Cyber Attacks

1. Malware Attack

   • Includes trojans, adware, spyware.
   • Occurs when suspicious attachments with malicious viruses are downloaded.

2. Phishing Attack

   • The type of attack Anne experienced.
   • Hackers send fraudulent emails appearing legitimate to steal sensitive information.

3. Man-in-the-Middle (MITM) Attack

   • Hacker intercepts the communication between Anne's device and server.
   • Common with unsecured Wi-Fi or through malware.

4. Password Attack

   • Cracking passwords using common sequences or brute force attempts.

Preventing Cyber Attacks

• Firewall: A virtual barrier filtering traffic between Anne's computer and the internet.
• Honeypots: Dummy systems to attract and deceive attackers, protecting real systems.
• Unique Alphanumeric Passwords: Strong, less predictable passwords.
• Antivirus Software: Protects against malware.
• Avoiding Unknown Emails: Reduces risk from phishing.

Cyber Attacks on Organizations

• Advanced Persistent Threat (APT): Extended access to networks to gather confidential information.
• Denial of Service (DoS) Attack: Networks flooded with traffic, blocking legitimate requests.
• Distributed Denial of Service (DDoS) Attack: Multiple systems launch the attack.
• SQL Injection Attack: Hackers manipulate SQL queries to access, edit, or delete database information.

Cybersecurity Professionals

• Ethical Hacker: Identifies and resolves vulnerabilities by simulating hacker tactics.
• Security Architect: Designs robust security structures.
• Chief Information Security Officer (CISO): Overall responsibility for an organization’s information safety.
