DDoS attacks are becoming more frequent, increasingly sophisticated, resulting in more significant losses of all time. Some organisations heavily rely on the old fashioned, outdated firewall solutions to protect themselves. If you are still one of them, an upgrade in the strategy or a more effective DDoS response plan is required to tackle the current threat landscape- no matter what your existing DDoS mitigation strategy looks like.
Strategy to build effective DDoS plan you need these necessary steps to make a robust protective system:
Create a Response plan:
Risk assessment, organisational roles and responsibilities, topics should be identified as the pillars of the strategy. The primary purpose of the program is to define the rules, procedure, resource and tools in the allotted budget to minimise any risk or loss associated with the attack.
It’s important to understand the scope of risk, which assets need protection or cost incurred if any asset goes missing. Recovery costs and importance of each associated asset versus the cost incurred for implementing DDoS protection for that asset.
Building Team to tackle DDoS response:
You need to include personnel who will do both strategising and execution part with expertise. They must be able to fulfil various tasks like identifying and mitigating an attack on coordinating with ISPs.
Identifying the points of failure:
The identification of single points of failure, whether it is the router or your DNS server, and how to minimise potential risk issues related to them. Without sufficient network visibility, organisations lack the information needed to understand the root cause of failure whether poor service or application performance is a result of DDoS attack traffic or a network misconfiguration.
Include your ISP in the Strategy
It’s important to include your ISP as massive attacks can strangle your bandwidth resulting in service degradation and service-level agreement violation. In some extreme cases, the ISP can even terminate your connectivity.
Test and Maintain
You don’t want to wait for an actual attack for testing you need to turn off your security services and check after 3-4 months and do the necessary updates so that your system continues to perform and there is no negative impact on the users.
