The Complete Guide To DDoS Attack Protection
DDoS (Distributed denial of service) aren’t new but the problem caused by them are spiking over the last few months. Here’s a complete guide from how to know if you are being attacked by DDoS to what can you do to prevent them.
What is DDos?
DDoS, as the name suggests is caused by heavy traffic from multiple machines. Traffic service received is being disrupted, so it cripples your network from all type of domains. Usually the source of traffic directed toward the target is by network of zombie computers. Also known as Botnet, the traffic generated by them is difficult to stop as the traffic is coming from multiple computers. Unlike DoS you can’t just stop the traffic by simply blocking one IP. You don’t have to be an expert to launch a DDoS attack; information is available at ddosprogram.com to demonstrate how to launch a DDoS attack. Due to these reasons, attacks by DDoS are major problems for anyone hosting a domain.
How to know if you are being attacked by DDoS
Lag and Isp problems should not be confused with DDos attacks. The determining process, whether you are experiencing DDos attacks, are very challenging. But you need to determine whether you are being DDoS’d or if its just another ISP problem.
DDoS attacks can cause the server to response late or give no response at all. If you’re experiencing this type of problem it’s a possibility that you’re being DDoSd. The server can be unresponsive due to many reasons. However, whatever the reason other than being attacked by DDoS, the effect is temporary. When you’re under DDoS attack your server can become unresponsive for a very prolonged time, even days. If this is happening to you it’s time to look into the matter.
The following steps illustrate how to check problem line by line.
1. Open your command prompt and enter ” ping google.com”
2. The default ping request is four however you can increase it by putting in the -n command for exact number of pings you want.
3. Take note of all the information displayed after the ping operation.
The information you noted will serve you as clues to your problem. If you find any that the info of time column disrupts heavily after each ping you may be a victim of DDoS attack. Heavy fluctuations in latency column can also indicate that you are being DDoSd.
An alternative way is to Enter the command netstat -q, this will display all the remote computers that you are connected to. Try it both times, when your server is working fine and when server is giving slow response and cell phone spy software reviews. If you find tremendous spike in numbers, you can be a victim of attack.
When stuck in situations like these it’s in your best interest to contact your ISP.
What to do to avoid getting DDoSd?
Follow these three points of safety:
1. Invest in technologies that will prevent your chance of experiencing the attacks.
2. Get help, acquire a host that’s an expert in mitigation, these specialists generally add IPs to access control list only allowing those IPs which need to connect.
3. Effective utilization of service is as important as buying the service.
The amount of investment may depend upon how much you are affected if you experience an attack. Although the initial cost is high for attaining services, the money spent will help your server to be always active.December 8, 2014
