4. Incident Reporting: Encouraging employees to report suspicious activities immediately.

5. Refusal of Administration (DoS) and Circulated Forswearing of Administration (DDoS) Assaults

 

What are DoS and DDoS Attacks?

A Denial of Service (DoS) attack aims to make a machine or network resource unavailable to its intended users by overwhelming it with a flood of illegitimate requests. A Distributed Denial of Service (DDoS) attack is similar but involves multiple compromised Cyber Threats a single target, making it more challenging to defend against.

Types of DoS and DDoS Attacks

1. Volume-Based Assaults: Overpower the transmission capacity of the objective.
2. Protocol Attacks: Exploit weaknesses in the protocol stacks to exhaust server resources.
3. Application Layer Attacks: Target the application layer to crash the web server.

Impact of DoS and DDoS Attacks

These Cyber Threats can cause significant downtime, loss of revenue, and reputational damage. They can also serve as a smokescreen for other malicious activities, such as data breaches.

Mitigation Strategies
