iStock_000005643842XSmallAn organization in Hawaii is working to construct one of the world’s largest telescopes, but that work came to a halt when their website was disrupted by an apparent cyberattack.

The Thirty Meter Telescope website was unavailable for about two hours after a Denial of Service (DoS) attack by the blog site Operation Green Rights. The group, along with other native Hawaiians, opposes the construction of the telescope because they believe the land it’s being built on is sacred.

Denial of service attacks are direct attempts to target a website with the intent of making it unavailable. These attacks work by sending repeated requests for communication to the server to the point where it becomes flooded with requests and cannot process any legitimate traffic.

Similar to the attack on Thirty Meter, most DoS attacks are the result of a campaign against a company’s actions or products. You can prevent a denial of service attack on your computing resources by following these three steps:

1. Install a firewall or other network protection device.

Proper configuration of network switches, routers, and firewalls can limit the effectiveness of a DoS attack.

2. Maintain strong anti-virus and anti-malware software on all computers on the network.

This software can help detect and prevent a computer from being used in a distributed denial of service attack (DDoS).

3. Monitor network activity and maintain network traffic baselines.

Intrusion detection and other intelligent hardware devices can identify network traffic, classify it as harmful or legitimate, and block it or allow it to pass.
