DoS Attacks

A Denial-of-Service (DoS) attack is a type of cyberattack in which a malicious actor attempts to make a computer system or network resource unavailable to its intended users. DoS attacks can take many forms, but all share the common goal of disrupting the victim's ability to access or use the targeted resource. DoS attacks can be launched from a single computer or from multiple computers working together in a botnet. They can be targeted at any type of computer system or network resource, including websites, servers, routers, and even entire networks.

Types of DoS Attacks

There are two main types of DoS attacks: Volumetric attacks and protocol attacks.

1. Volumetric attacks flood the target system with so much traffic that it becomes overwhelmed and unable to process legitimate requests. These attacks can be launched from a single computer or from multiple computers working together in a botnet. Volumetric attacks include:
2. • UDP flood
   • TCP flood
   • ICMP flood
   • DNS flood
3. Protocol attacks exploit weaknesses in the protocols used by computer systems and networks. These attacks can be more difficult to detect and defend against than volumetric attacks. Protocol attacks include:
4. • SYN flood
   • Smurf attack
   • Teardrop attack

Impact of DoS Attacks

DoS attacks can have a significant impact on their victims. They can cause:

• Website outages
• Server crashes
• Network congestion
• Data loss
• Financial losses
• Reputational damage

Defending Against DoS Attacks

There are a number of measures that can be taken to defend against DoS attacks, including:

• Using firewalls to block malicious traffic
• Implementing intrusion detection systems to detect and block attacks
• Limiting the number of connections that can be made to a system or network
• Using rate-limiting to prevent attackers from sending too many requests to a system or network
• Using blacklists to block known malicious IP addresses
• Implementing DDoS mitigation services
