Defending Your Server From Ddos Attacks
November 23, 2015
Your server may be at risks from various viruses and Trojans surfing the internet or propagated by hackers around the world. These risks are extremely dangerous and can stall your system permanently. The virus can attack your system causing the server to decrease its efficiency and its performance. The virus can block the bandwidth of your server, resulting in delayed process or sometimes result in page opening failure. It is thus necessary to get your server protected from DDoS (Distributed Denial of Service), spam attacks and other malware that can compromise your security.
DDoS is an attack perpetrated by hackers by flooding the bandwidth of the host with unwanted spam and IP requests. These docile requests block the ports of the server thus causing the server to temporarily or permanently shut down. Multiple computers are commanded to send such docile requests to the target server to create a bottleneck on the website causing the webpage to decline the request of potential clients. Commanding computers to send requests to a server without the knowledge of the user is called a botnet. A DDoS protected dedicated server will scrutinize the requests and filter them to avoid spam emails. These servers are high security servers and provide maximum efficiency.
Here are some ways in which you can defend your server from attacks from viruses:
Firewalls: Firewalls can block many incoming attacks from IP addresses or ports. This defense mechanism is based on protocols and is not useful for complex situations. Firewalls stop the incoming traffic to the server which also includes legitimate traffic. Hence setting up a firewall is not recommended for creating a DDoS protected dedicated server.
Application Front End Hardware: Application front end hardware is the hardware installed to network before the incoming traffic reaches the server to distinguish between legitimate traffic and bogus traffic. Application Front End hardware analyzes the packet data and checks it for malware and hence segregates it into priority, regular and dangerous.
Application level key Completion Indicators: To check whether the incoming traffic bulk is legitimate or not, application level key completion indicators are installed which monitors the macroscopic events to determine whether the traffic is bogus or not.
DDS (DoS Defense System): This defense system is important to check whether the traffic is legitimate or no. Some traffic are made with legitimate content but are meant to hamper the bandwidth of the website. The DDS will restrict the traffic which has legitimate content but bad intent.
To create a DDoS protected dedicated server, you need to install the above security options to make your server free from any inevitable attacks from hackers. A server free from viruses will give you maximum efficiency and performance. Hence it is necessary for you to look for symptoms of a virus attack on your server at regular intervals of time. DDoS attacks can also destroy your security systems and compromise your security. There are various service providers that deal with installing firewalls and security services.
