Understanding Cyber Attacks and Prevention

Introduction to Anne's Experience

Meet Anne, a frequent shopper at www.shoppingcart.com, who has her personal information saved for convenience.

Anne receives a seemingly legitimate email about a discount voucher, prompting her to enter her account credentials without suspicion.

This leads to unauthorized access of her account by a hacker, resulting in significant financial loss.

Types of Cyber Attacks

Cyber attacks can vary; one common type is malware attacks (e.g., Trojan, adware, spyware).

Phishing attacks involve fraudulent emails that appear legitimate to steal sensitive data or install malware.

Man-in-the-middle attacks occur when hackers intercept communication between the user and the server, often exploiting unsecured networks.

Password attacks exploit weak passwords through guessing or using common combinations.

Implementing Cyber Security Measures

To prevent future incidents, Anne installs a firewall that filters incoming and outgoing traffic to protect her network.

She also implements honeypots—decoy systems designed to attract attackers away from real systems.

Additional measures include using unique alphanumeric passwords and antivirus software while avoiding unknown emails.

Impact on Organizations

Cyber attacks are not limited to individuals; organizations face severe threats leading to substantial losses.

Advanced Persistent Threat (APT): Hackers gain prolonged access for continuous data theft.

Denial of Service (DoS): Networks are overwhelmed with traffic, leaving legitimate requests unattended. A variant is Distributed Denial of Service (DDoS).

The Role of Cyber Security Professionals

Ethical hackers identify vulnerabilities in networks similarly to malicious hackers but aim for protection against actual threats.

Security architects design robust security structures within organizations. Chief Information Security Officers (CISOs) oversee overall information safety.

Conclusion: The Growing Need for Cyber Security Experts

With increasing digital data production, cyber attacks are expected to rise significantly.
