Distributed denial of service or DDOS attacks can be harmful for a business in terms of lost revenue and additional expenditures. Preventing these attacks has a vital role in helping your online business run smoothly. In this article, we shall talk about some of the useful ways that can be utilized to ensure an uninterrupted delivery of services to your consumers.
Switches for DDOS Mitigation
Made with an automatic control list capacity, switches can regulate data flow in a number of ways. They can use several techniques such as delayed binding, deep packet inspection, bogon filtering or traffic shaping as well as can control data floods at the system level. Each technique has its individual role to play. For instance, traffic shaping is a way to limit traffic rate, and helps forgo to increase the functional bandwidth of specific traffic. As a network administrator, you can explore one of these options and set them manually or as default settings to prevent DDOS attacks.
Necessary Measures at Firewall Level
There are simple networking rules that can help network administrators allow or block protocols, ports or IPs within the network. While firewalls may not be that intelligent to control good traffic, they can help preventing internal flooding attacks on the system. However, some complex attacks can be very difficult to determine since you cannot clog all the traffic to a point because this may stop genuine traffic from reaching to the server. Also, insignificant firewalls within the network are usually not very helpful as there can be a blockage in routers before the traffic reaches the firewall. Even so, you can utilize firewalls as a form of great defense to combat simple DDOS attacks.
Sink Holing and Black Holing
Black holing is used to send incoming traffic that will affect a server to an imaginary IP address. Sing holding, on the other hand, can be used to send traffic to an existent IP address so it can receive incoming traffic and filter it to eliminate bad traffic.
Using an appropriate testing platform to recognize weak areas within a network is another technique to prevent DDOS attacks. You can use the information received from this system to regulate the settings of both manual and automated systems that are handy to have back up in the event of a DDOS attack on the network.
Clean/scrub center Utilization
Cleaning or scrubbing center separates genuine traffic from all types of suspected traffic including those causing DDOS attacks on the network. In order to benefit from this facility, your network must have a strong internet connection. There are numerous techniques such as proxies, direct circuits and tunnels that can be used to clean the incoming traffic on your network.
Prevention at the Router Level
Another simple way to prevent DDOS attacks is to set the limits of the router by configuring a control list. These changes will help the routers prevent the request flow coming from a potential DDOS attack whilst keeping the network easily accessible to its genuine users.
DDOS attacks can be very damaging to any business’s reputation. They can obstruct the overall performance by overwhelming the traffic flow to a network/service, often making it inaccessible to the genuine audience. The given strategies in this article can be helpful in preventing these cyber-attacks and keeping up the network run smoothly.
