□ Type of DDoS solution
To prepare for DDoS attacks, various DDoS defense solutions have been developed. These solutions protect networks and systems by providing traffic monitoring, detection and blocking capabilities. Commonly used DDoS solutions include:
 |
| DDoS solution products |
▶ Network Firewall
A firewall is responsible for monitoring network traffic and blocking malicious traffic. When a DDoS attack is detected, the firewall blocks that traffic and prevents it from reaching the target server. Network firewalls detect and block attacks by setting policies based on traffic's source IP, port, protocol, and more.
▶ Load Balancer
A load balancer serves to increase the availability of a service by distributing traffic to multiple target servers. In the event of a DDoS attack, the load balancer reduces server load by forwarding traffic only to legitimate servers and filtering out malicious traffic.
▶Intranet Firewall
An intranet firewall prevents DDoS attacks originating from the internal network. When an infected computer or device on the internal network attempts to launch a DDoS attack, the intranet firewall detects and blocks it, preventing it from propagating to the external network.
▶Internet service provider (ISP) cooperation
ISPs can prepare for DDoS attacks and provide their own traffic filtering or blocking capabilities. The ISP is responsible for monitoring the traffic to the target server and blocking malicious traffic to keep the target server available.
▶ Cloud-based DDoS protection service
Cloud service providers provide cloud-based DDoS protection services against DDoS attacks.
□ DDoS solution Function
▶ Traffic Scrubbing
The DDoS solution monitors and analyzes all traffic entering the target system and filters abnormal packets. To this end, the DDoS solution collects and analyzes all packets entering the target system, and generally uses software or hardware-based DDoS defense equipment for this purpose.
▶ Traffic Shaping
DDoS solutions reduce the load on the target system by managing traffic according to flow. For example, to defend against volumetric attacks that generate large amounts of traffic, DDoS solutions reduce bandwidth utilization by distributing incoming traffic to the target system.
▶ Anomaly Detection
The solution detects unusual behavior by monitoring traffic patterns coming into the target system. Anomaly detection is typically implemented using machine learning, artificial intelligence, or behavior-based detection.
▶ Cloud-Based Protection
To defend against massive DDoS attacks, some DDoS solutions offer cloud-based protection. To this end, cloud service providers use a method to protect customers' Internet connections, filter large amounts of traffic, and pass only normal traffic to the target system.
▶ Redundancy
In order to prevent the target system from being down due to a DDoS attack, the DDoS solution provides a function to ensure the resiliency of the target system.
□ DDos solution products
Several companies offer a variety of products and solutions to protect against DDoS attacks. Below are examples of some popular DDoS products and solutions.
▶ AhnLab TrusGuard DPX
The main features of AhnLab TrusGuard DPX are as follows.
 |
| AhnLab TrusGuard DPX |
DDoS attack detection: TrusGuard DPX detects and analyzes various types of DDoS attacks. This allows you to identify DDoS attacks in real time and take action.
Traffic analysis and filtering: The solution analyzes large volumes of traffic in real time to distinguish legitimate traffic from malicious traffic. Malicious traffic is filtered and blocked from reaching the target system.
Virtualization and Distributed Defense: TrusGuard DPX operates in a virtual environment, and provides preparation for DDoS attacks and load balancing by distributing to multiple servers or devices.
Behavior-based detection: Solutions can analyze the traffic patterns of target systems to identify unusual behavior or behavior, and take countermeasures against them.
Real-time Response and Reporting: TrusGuard DPX takes countermeasures against DDoS attacks in real-time and provides alerts and reports to administrators, enabling rapid response.
AhnLab TrusGuard DPX is known as a powerful solution that helps prepare against DDoS attacks to protect networks and servers. Information on detailed features and configuration of the product can be found on AhnLab's official website or product documentation.
▶ Arbor Networks
Arbor Networks is a leading provider of DDoS attack detection and prevention solutions. Arbor DDoS Protection provides traffic analysis, malicious traffic filtering, behavior-based detection, and cloud-based protection.
▶ Radware
Radware is a company that provides DDoS protection and application delivery control (ADC) solutions. Radware's DDoS protection product, DefensePro, mitigates DDoS attacks through real-time traffic analysis, malicious traffic filtering, and script-based attack detection.
▶ F5 Networks
F5 Networks specializes in providing application delivery and security solutions. Silverline DDoS Protection, F5's DDoS protection product, provides visibility, traffic filtering, malicious traffic recognition, and application-level protection.
▶ Cloudflare
Cloudflare is a company that provides cloud-based security and performance optimization solutions. Cloudflare's DDoS protection service provides the ability to detect and block attacks by analyzing the traffic coming into the target system.
▶ Akamai Technologies
Akamai operates a globally distributed content delivery network (CDN) and also provides DDoS protection solutions. Akamai's Kona DDoS Defender mitigates DDoS attacks by analyzing traffic, providing visibility, and intelligent filtering.
In addition to this, many companies offer DDoS protection products and services, each with its own unique features and functions. In order to select an appropriate product that meets the company's requirements and budget, it is necessary to consider the product's performance, scalability, availability, management and monitoring functions, etc.
