Welcome back to the Kosciusko Connect blog series on internet-based scams and cyberattacks. In our previous articles, we covered a range of threats, from phishing to ransomware. Today, we will look at another menacing cyber threat: Denial-of-Service (DoS) attacks. These attacks can disrupt your online world and cause havoc, making it crucial to understand what they are, how they work, and how to protect yourself.
Denial-of-Service attacks, often abbreviated as DoS attacks, are cyberattacks designed to make online services, websites, or networks unavailable by overwhelming them with a flood of malicious traffic. The primary goal of a DoS attack is to disrupt the normal functioning of a targeted system, rendering it inaccessible to its intended users. In essence, it's like jamming a busy road with an endless stream of vehicles, making it impossible for anyone to get through.
Ping Flood: In this type of attack, the attacker sends an overwhelming number of ping requests to a target server, causing it to become slow or unresponsive.
HTTP Flood: Attackers bombard a web server with an excessive number of HTTP requests, often resulting in a website becoming unreachable.
SYN Flood: This attack exploits the three-way handshake process in TCP/IP communication. The attacker floods the target with SYN (synchronization) requests, causing it to run out of resources and crash.
DNS Amplification: Attackers use poorly configured DNS servers to amplify the volume of traffic directed at a target. This can lead to network congestion and service disruption.
The threat of Denial-of-Service attacks is real and continues to grow. According to recent cybersecurity reports:
In the United States, there was a 150% increase in reported DoS attacks in the past year.
Small and medium-sized businesses are increasingly becoming targets, with 60% of DoS attacks aimed at this sector.
The average cost of mitigating a DoS attack in the U.S. is estimated to be around $120,000, including downtime and security measures.
Now that we understand the gravity of DoS attacks, let's explore how you can recognize and protect yourself from them:
Stay Informed: Keep up to date with the latest cybersecurity news and trends. Awareness is your first line of defense.

Content Delivery Networks (CDNs): Business owners and website managers should consider using CDNs to distribute traffic across multiple servers, which can help absorb the impact of an attack.
Incident Response Plan: Develop an incident response plan to quickly mitigate the effects of a DoS attack should one occur.
Traffic Monitoring: Continuously monitor your network traffic for unusual spikes that could indicate an attack in progress.
Seek Professional Help: If you suspect a DoS attack, contact your internet service provider or a cybersecurity expert to help mitigate the attack.
Denial-of-Service attacks are a serious threat in today's digital landscape. By understanding what they are, recognizing their signs, and taking proactive steps to protect your online presence, you can defend against this disruptive menace.
