Businesses today rely heavily on the internet for services; hence, due to cyber attacks, the horizon is now looming quite large. Distributed Denial of Service is one of the lethal and prevalent forms of cyber-attacks. These types of threats can blow up the network infrastructure of any organization into vast amounts of downtowns, damaging the brand’s revenue and reputation.
Below are different types of DDoS attacks and mitigation techniques that can safeguard your network from such threats, which never seem to end. It is therefore prudent to be aware that Distributed Denial of Service attacks have increased in the last two decades in terms of incidents and the level of sophistication adopted.
Anatomy of DDoS Attacks
Volumetric Attacks
Volumetric is the most common form of DDoS attack. In a volumetric attack, overwhelming traffic is sent to the target in a volume more significant than the capacity of the target’s bandwidth. Such threats flood the network with high volumes of data packets, exhausting all available resources and services. These attacks include UDP floods, ICMP floods, and DNS amplification attacks. Traffic filtering mechanisms can be implemented to counter volumetric attacks.
Attacks in the Application Layer
The application layer attacks are layer seven, focusing on attacking particular software applications rather than the network infrastructure. Application layer attacks are directed against the protocols that form the base of communication over the web, namely HTTP, HTTPS, and DNS, to overwhelm web servers and applications. Some standard techniques by which these floods had been created include HTTP floods, Slowloris attacks, and SYN floods.
Protocol Attacks
Protocol attacks aim to take advantage of the insecure nature of certain network protocols, which in this case, will include TCP, UDP, and ICMP. In so doing, it prevents devices and services from communicating with each other, hence giving the impression that the protocol stack’s lower-level infrastructure of a network has not replied or has crashed. Examples include SYN floods, ICMP floods, and UDP floods. In particular, mechanisms that guarantee rate limiting, protocol validation checks, and stateful packet inspection to detect and block malicious traffic are needed.
Protection Against DDoS Attacks
Deploy DDoS Mitigation Solutions
Deploy DDoS mitigation solutions that potentially save your network from such threats. The solution implements complex algorithms and machine learning to identify and neutralize attacks within the shortest time frame. Also, volumetric and application-layer attacks are efficiently prevented due to continued monitoring of network traffic and applying adaptive mitigation strategies.
Implement Network Segmentation
Network segmentation is a process of segregating the network into smaller pieces called segments, which helps reduce its impact in case of an attack. This means that organizing essential components of the infrastructure and services in different segments can enable organizations to contain the attack’s dissemination throughout the network.
Work with ISPs and DDoS protection organizations.
Collaboration with Internet Service Providers (ISPs) and Distributed denial-of-service protection providers can offer an additional layer of defense against these attacks. Most ISPs do offer mitigating features to redirect and filter malicious traffic. Similarly, collaboration with specialized DDoS protection providers can also use their experience and resources to reduce such threats.
Strengthen Incident Response End
An excellent response to these incidents must reduce the impact and restore operations to normal within the minimum possible time. Organizations need to make proper response planning, adequately outlining roles, responsibilities, and procedures for response. This feature would involve opening the lines of communication and response coordination to establish countermeasures with a better chance of minimizing the attack’s impact.
Types of DDoS attacks present an immense danger to any organization, regardless of size. Knowing the anatomy of your network and using mitigation strategies can go a long way in keeping it safe from these growing threats. Utilize DDoS mitigation solutions, network segmentation, and collaboration with an ISP and a DDoS security provider, which can also enhance your incident response capabilities.
