Too Expensive to Attack: Enlarge the Attack Expense through Joint Defense at the Edge
This addresses cybersecurity for businesses and individuals reliant on the Internet, offering a novel collaborative defense approach.
The paper tackles DDoS attacks on vulnerable edge servers by proposing a joint defense framework that significantly increases the required number of bots and attack expenses, with evaluations showing expenses can surge up to thousands of times, preventing further attacks.
The distributed denial of service (DDoS) attack is detrimental to businesses and individuals as people are heavily relying on the Internet. Due to remarkable profits, crackers favor DDoS as cybersecurity weapons to attack a victim. Even worse, edge servers are more vulnerable. Current solutions lack adequate consideration to the expense of attackers and inter-defender collaborations. Hence, we revisit the DDoS attack and defense, clarifying the advantages and disadvantages of both parties. We further propose a joint defense framework to defeat attackers by incurring a significant increment of required bots and enlarging attack expenses. The quantitative evaluation and experimental assessment showcase that such expense can surge up to thousands of times. The skyrocket of expenses leads to heavy loss to the cracker, which prevents further attacks.
