1. Difference between virus, worm, and ransomware

1.Virus:
A malicious program that attaches itself to a legitimate file or program. It spreads when the infected file is executed and often requires user action to activate.

2.Worm:
A standalone malware that spreads automatically across networks without needing a host file or user interaction. It mainly exploits system vulnerabilities.

3.Ransomware:
A type of malware that locks or encrypts a victim’s data and demands payment (ransom) to restore access.

2. Steps of a typical phishing attack + employee training

Phishing attack steps:

Preparation: Attacker creates fake emails, messages, or websites that look legitimate.
Delivery: The phishing message is sent via email, SMS, or social media.
Deception: The message tricks the victim into clicking a link or opening an attachment.
Data capture: Victim enters sensitive information (passwords, credit card data) on a fake site or downloads malware.
Exploitation: Attacker uses stolen data for fraud or system access.

3. What is a DDoS attack and its impact on availability?

A Distributed Denial-of-Service (DDoS) attack occurs when multiple compromised devices (a botnet) flood a server, website, or network with massive traffic, overwhelming its capacity.

Impact on business availability:

Website or service becomes extremely slow or completely unavailable

Legitimate users cannot access the system

Loss of revenue (especially for e-commerce platforms)

Damage to brand reputation and customer trust

Potential downtime for critical services
