Backing Up Defenses against DDOS Attacks

Backing Up Defenses against DDOS Attacks

DDoS stands for Distributed Denial of Service. DDoS is a type of DOS attack where multiple compromised systems, which are often infected with a Trojan, are used to target a single system causing a Denial of Service (DoS) attack. This kind of attack tries to make a computer resource unavailable to users.

Examples of the legitimate tools used are in helping, socket programming, and httping. There are also underground tools available for such attacks.

Signs DDoS

Signs Of A DDoS Attack

• The US Computer Emergency Response Team defines symptoms of a DDoS attack as :

• Unusually slow network performance, either processes or opening files. Unavailability of a website. 

• Inability to access a web site. Dramatic increase in spam emails, this is an email bomb.

DDoS attacks lead to issues with branches of a network being attacked. The attack over loads the network; other branches will try to compensate for the increase in traffic

• This causes the whole network to slow down. A large enough attack can shut down entire regions of internet connectivity.

The DDoS Attack May Also Use Malware To Cause Further Damage:

• Max out the processor’s usage so no work gets done

• Cause Microcode errors in the machine

• Lock up the computer by giving the processor erroneous sequencing

• Locking up the computer through the operating system through resource starvation.

• Crashing the operating system itself.

Defending using DDoS Protection

Defending Against DDoS Attacks:

• Recognize the signs of a DDoS attack. The first and best defense against a DDoS attack is the ability to recognize it early. Unfortunately, not all DDoS attacks are easy to distinguish from normal spikes in network or web traffic or a sudden slowdown in network performance.

• DDoS attacks can take a website down quickly and emphatically. By knowing what you are facing you can defend against them. 

• DDoS Attacks range from brute force incursions to surgical strikes against key components of a network. The right tools to set up your defenses and a DDoS attack can be stopped cold.

Consider our advice to help prevent attackers from shutting down your network with a flood of unwanted traffic. Have an incident response plan in place and talk about DDoS countermeasures in advance with your ISP and a service provider that specializes in mitigating these types of attacks.
