DDoS Protection

What is SIEM software? How it works and how to choose the right tool

Evolving beyond its log-management roots, today's security information and event management (SIEM) software vendors are introducing machine learning, advanced statistical analysis and other analytic methods to their products.


DDoS stands for a ‘distributed denial-of-service’. The DDoS attack is a kind of malicious attempt to disturb the normal traffic in a specific server, service or network. It is often done by overwhelming the target. The surrounding infrastructure of internet traffic is often flooded by this attack. Only blocking a single source can not alone stop this attack. It is like an illegitimate crowd jamming the entry of a shop stopping the legitimate customers to have entry to the shop.DDoS attack applies on selling website(e-commerce), bank, the gateway of transmission, credit card payment gateway for blackmail and personal revenge.

Attack on a website or server by increasing trafficking requests and it can do multiple computers together or use a zombie computer for attack by using multiple computers and creating overload trafficking requests which are can’t get the load on the server(means server capacity).

Case study

There are many companies around the world like airline companies, bank agency being attacked by DDoS. It stopped the companies’ sale process by stopping genuine customers to have access to their website. It not only bring their website down but also paralyzed their operations. Sometimes the business servers become so affected that many companies want to shut them down. The severe harm it can do is it often compromises online information and infrastructure. When this happens, it causes irreparable damage to the company and losing their image as well.

Problem statement

 DoS attack prevents legitimate users from accessing the required resource network and server and website. It consumes bandwidth, file space, memory as well as CPU. The server is unable to respond to legitimate users for overload trafficking. A Distributed Denial of Service (DDoS) can be considered to be a subset of a Denia Read more


The approach to solving the networks and computers from being attacked is applying preventive measures and by using network simulation which simulates server system and network performance. DDoS can be prevented by configuring routers at the network layer when possible. This attack can be also prevented by blocking internet attacks from websites. Blocking attacks with packet filters on a router is another effective solution.  Likewise, the attacks can be blocked by configuring the firewalls.There have two filtering ways - ingress filtering and egress f Read more
