Distributed denial-of – service (DDoS ) attacks are malicious attempts that focus on interrupting a targeted server, network, or service ‘s normal traffic by overwhelming the target or its surrounding infrastructure with an Internet traffic overflow. DDoS attacks use multiple compromised computer systems as sources of traffic in attack. Computers and many other networked tools such as Internet of Things ( IoT) devices can be used in managed machines. Thus, a DDoS attack can be likened to a traffic jam that clogs up with a highway, stopping normal traffic from reaching its destination of choice.
Let’s look at some key ways to protect yourself from DDoS attacks:
Let your architecture look as robust as possible
It ‘s essential that you make the architecture as robust as possible to reinforce resources against a DDoS attack. This idea of strengthening network architecture is a vital step not only in the preservation of the DDoS network but also in maintaining business continuity and security from unforeseen situations of various kinds. Architecture priorities in general should be providing diversity, eliminating bottlenecks and geographic diversity. While these are considered best practices for the continuation of general business and the recovery of disasters, they can also help to ensure organizational resilience in response to an attack by DDoS.
Create an Action Plan for DDoS
Before you get hit by one such attack, your company will have to start planning to protect against DDoS attacks. Build a system that can help you withstand a DDoS attack, helping you to mitigate the risk when there is one. A DDoS action plan might address the use of automated reports to send an internal alert when your traffic goes well beyond normal levels. It’s also important to document your IT infrastructure with an asset inventory to develop a network topology diagram.
Make sure you have more bandwidth
Over-provisioning of your bandwidth gives you additional time to detect and handle a DDoS attack. In addition , extra bandwidth allows your server to accommodate unforeseen spikes in traffic, cushioning you against a potent attack.
Making your IoT devices more stable
DDoS attacks are increasing constant, and hackers are now exploiting massive IoT device-composed botnets worldwide. Businesses and consumers must improve the security of their devices to reduce the attack power of DDoS attacks. One effective way to get this done is by updating factory-set passwords from default – easily guessed by hackers using brute force methods. Always ensure strong passwords are created and they are changed regularly.
Use a Content Delivery Network (CDN)
The use of a Content Delivery Network (CDN) is considered one of the best protections against an attack by DDoS. CDNs are responsible for identifying traffic started as part of a DDoS attack and then diverting it to a cloud infrastructure of third parties.
Blacklist and Whitelist
Using blacklists and whitelists will help you monitor who can access your network and APIs. You need to be careful though, as it is important not to automatically blacklist IP addresses that activate alerts to the network. You will have to temporarily block traffic and analyze how it responds to gage whether it is malicious or real. Legitimate users will generally try again after a few minutes while unlawful traffic tends to switch IP addresses.
Block spoofed IP addresses
Spoofing is known to be an internet impersonation of a computer, user or client, often used during a cyberattack to mask the source of the traffic of an attacker. IP spoofing is employed during a DDoS attack to mask positions of botnet devices and stage what is called a reflected attack. There are a number of services that block spoofed IP addresses. Current solutions include deep packet inspection (DPI), which looks at packets rather than just sourcing IP addresses. However, DPI is a resource-intensive and costly operation, so you’ll probably need to outsource it to a third party provider.
Upgrades to Hardware
A lot of hardware on network will mitigate different types of DDoS attacks. For example , a number of commercially available network firewalls and load balancers can effectively protect a business from app layer attacks and layer 4 attacks. Hardware upgrades also serve to protect against SYN flood attacks.
Get Fixhackedwebsite to take protection from DDoS attacks
Fixhackedwebsite has developed an all-in-one web security tool which can prevent DDoS attacks. This web security framework has a Web Application Firewall ( WAF) capable of removing vulnerabilities in the application and defending web applications and websites from advanced attacks like DDoS, SQL injection, and cross-site scripting.
The functionality of Fixhackedwebsite WAF is as follows:
DDoS protection: Globally distributed Anycast network allows for efficient traffic distribution. It specifically blocks all traffic based on nonHTTP / HTTPS, with a current network capacity of more than 1 TB / s. Each PoP has multiple 10 G and 100 G ports which are designed to scale and absorb extremely large attacks.
Prevention of malicious bot and brute force: This WAF blocks malicious bots and website brute force attacks. It also protects account registration forms and login pages from various attack vectors including protection from denial of service application , web scraping, and reconnaissance attacks.
Zero day immediate response: Fixhackedwebsite WAF provides regular updates of virtual patches for all websites under management and instant reaction to apply a patch for the zero day attacks when they become publicly known.
Stop attacks and hacks on websites: Protect vulnerable websites by detecting and removing malicious requests and preventing attempted hacking. This WAF is also based on device targeting attacks such as Drupal , Joomla, WordPress and plugins etc.
Other security features which Fixhackedwebsite offers include:
