Black hat hackers can be very aggressive when they want to target a website. Some hackers use distributed denial of service (DDOS) attacks to take the site down. You will need to know what to do to protect yourself if a hacker tries to take down your site.
Protecting Yourself Against a DDOS Attack
DDOS attacks are some of the most sophisticated attacks many hackers use. They can be conducted in a variety of ways. One of the ways hackers use DDOS attacks is by infecting a network of computers and using them to flood a server or website with traffic. The server will eventually shut down when it can no longer handle the traffic.
The good news is that DDOS attacks are actually pretty rare against most small websites. Hackers generally use these attacks against larger sites for either financial gain or on idealistic grounds. However, you should still be prepared in case your site is the target of a DDOS attack. Here are some things that you will want to know. You can read more here if you would like more tips.
Monitor Your Services
There are a number of scripts that you can run to see if there is anything wrong on these servers. The script will let you know if the traffic levels are increasing significantly. This is a sign that you may be the victim of a DDOS attack and will need to take defensive action.
Increase Your Bandwidth
One way to reduce the effectiveness of a DDOS attack is to increase your bandwidth. This can be costly, but it is also the easiest way to stop hackers from taking the site down.
Hackers have to take the cost of a DDOS attack into consideration. If you buy enough bandwidth, many of them will give up trying to execute an attack. Some truly dedicated or obsessed hackers may continue, but you will have at least reduced the likelihood of an attack.
Purchase Enhanced DNS Security
You can take a number of measures to protect your website from being taken down. Unfortunately, these strategies won’t do you much good if the hacker successfully deploys a DDOS attack against the servers. You will need to make sure that your servers can withstand a coordinated DDOS attack.
You can purchase enhanced DNS security for better protection. Your DNS servers won’t be directly exposed to hackers, which will make it more difficult for them to launch a DDOS attack of cache poisoning against you.
Drop Junk Packets
You will want to find out if any junk packets are trying to connect to your site. This is especially important if you are managing your own hosting.
One way to do this is to use the IP verify unicast reverse-path interface command. This will allow you to see what IP addresses computers are trying to connect from and see if it has a route in the CEF tables on the same interface. Your router will drop the packet if the IP can’t be verified.
