Understanding DDoS Attacks: Risks, Trends, and Prevention Strategies

What Is a DDoS Attack

DDoS (Distributed Denial of Service) attacks involve a large number of compromised computers or attackers sending massive amounts of seemingly legitimate requests to a server, overwhelming its capacity and causing slowdowns or crashes. The attacks are coordinated through botnets and are therefore called distributed denial‑of‑service attacks.

Harms of DDoS Attacks

Business Impact

Online platforms such as gaming, e‑learning, e‑commerce, finance, and live‑streaming lose traffic and revenue when their servers become inaccessible. Surveys show that 26% of attacked enterprises view loss of business opportunities as the most serious consequence.

Reputation Damage

Service outages lead to poor user experience, complaints, and loss of trust. About 37% of companies report reputation harm, one‑third see credit‑rating impacts, and many experience higher insurance premiums after an attack.

Data Leakage

Attackers often use DDoS as a smokescreen for other crimes. When a site is overwhelmed, defenders focus on mitigation, allowing data theft, malware infection, or deception to succeed. Studies indicate that one in three DDoS events is combined with network intrusion, resulting in significant data loss.

DDoS Attack Trends

According to Neustar, the number, size, and intensity of attacks have risen sharply in the first half of the year. Small attacks (≤5 Gbps) grew by over 200%, while large attacks (≥100 Gbps) increased by 275%.

How to Prevent DDoS Attacks

Two common mitigation approaches are used:

If the attack traffic is modest, increasing bandwidth at the data center can absorb it.

For large‑scale attacks, professional DDoS protection services (e.g., high‑defense IP) filter malicious traffic before it reaches the origin server, ensuring stable operation.

Experts recommend selecting an appropriate high‑defense solution early, before an outage occurs, to avoid irrecoverable losses.
