Regardless of its size, every financial institution must have a DDoS protection, remediation, and preparedness strategy.
Distributed Denial of Service (DDoS) attacks on businesses are an increasingly alarming trend. Whether it’s for compromising data security, intellectual property theft, or cyber espionage, DDoS hacks provide a way to degrade server and communications performance, to test and probe infrastructure security, and to disguise any incursion attempts.
Types of DDoS Attacks
Generally speaking, there are 3 kinds of DDoS attacks:
1. Protocol-Based Attacks
These are created to eat up server resources by exploiting particular communications protocols.
2. Volume-Based Attacks
These depend on high-traffic volumes to prevent or reduce access to a server.
3. Application-Based Attacks
These attack the code that runs at the application layer to crash or degrade servers.
Each of these attacks is distinct and thus requires different technologies to detect and remedy. As such, several factors need to be considered such as how quickly a response can be launched, the cost of defensive cybersecurity or DDoS protection, the methods of detection, and the target being attacked. In other words, you need a strategic approach to protect your business’ critical infrastructure.
Creating a Rock-Solid DDoS Protection Strategy
A DDoS protection plan — which means implementing DDoS protection technologies and hoping they never have to be used — is not enough to defend your business infrastructure. Here’s what you need to do:
Evaluate Your Assets
First things first, identify which of your assets are absolutely vital to your business. These usually include application servers, web server, VPN services, email systems – essentially, any asset that will effectively halt your business operations should they become compromised or impacted in any way.
Assign reasonably estimated time duration and a downtime dollar value to repair as well as any other metrics relevant to your organization’s network security evaluation to pinpoint critical assets.
Set up Strong DDoS Protection Measures
The DDoS protection strategy you choose for your infrastructure must be cutting-edge, with a reliable track record. You may want to analyze your vendor’s responsiveness and support options, and then work with them to create a robust mitigation system with regular test protocols. It is vital that you know for sure that your deployment will work without a hitch in the event of a DDoS attack.
Get Visibility into Your Network
One of the keys to in-depth DDoS protection and detection is being able to recognize abnormal packet flows and events and understanding what the “normal” traffic patterns are. For example, if someone uses DDoS to degrade your connectivity – rather than executing an all-out network assault – you may not even notice the attack if you don’t have an idea of what’s normal.
Keep in mind that traffic patterns change over time (like they did post-COVID-19 pandemic), so keep re-evaluating your network to understand what your normal traffic pattern is.
Utilize Deep Packet Inspection
An application-level deep packet inspection is the final step in your DDoS protection strategy. You need to monitor your inbound traffic as well as the outbound traffic. Also keep an eye on inappropriate content like credit card numbers, and any dangerous and unauthorized payloads.
