Mirai, a massive botnet made up of millions of hijacked Internet of Things (IoT) smart devices such as web-enabled cameras and routers, was unleashed to wreak havoc.
#1 Know What Mirai Is
Before they were sold to customers, Mirai was created by a failure by vendors to protect new internet-enabled gadgets, like smartwatches, or conventional appliances like kettles and toasters. This is why we now have the Mirai botnet.
A successful DDoS attack may have severe consequences, erasing your firm from the internet and rendering it unable to engage with consumers. Therefore, you must read the Mirai botnet attack analysis and apply a proper strategy to defend your system.
#2 Detect The DDoS Attack As Soon As Possible
To protect your servers, you must be able to tell when they’re being targeted. The sooner you can determine that a DDoS assault causes your website’s troubles, the sooner you can halt the DDoS attack.
Knowing your regular incoming traffic profile can help you identify when your traffic profile changes. Therefore, it’s a good idea to acquaint yourself with what your typical traffic looks like. You can detect whether you’re dealing with a DDoS assault by looking for abrupt surges in traffic.
#3 It’s better to have more bandwidth than you need
As a general rule, it would be best if you had more bandwidth accessible to your Web server than you believe you’ll ever need. Your website can handle spikes in traffic from advertising campaigns, special offers, or even a mention in the media, so you don’t have to worry about unexpected traffic surges.
Regardless of how much overprovisioning you do, a DDoS assault is still likely to occur. You may have a few more minutes to act before your resources are entirely overloaded.
#4 Protect Your Network’s Perimeter (If You Run Your Own Web Server)
In the initial few minutes after an assault, a few easy technical steps may be performed to lessen the damage. You may, for instance, do as follows:
- Avoid overloading your Web server by limiting the bandwidth of your network.
- To prevent attacks from timeout half-open connections, use filters to instruct your router to discard packets from certain sources.
- Set lower SYN, ICMP, and UDP flood drop levels to discard spoofed or faulty packets more aggressively.
While these techniques have been successful in the past, DDoS assaults are currently frequently too massive for these procedures to halt a DDoS attack. The most you can hope for is that they’ll give you some time to deal with a DDoS assault before it gets out of hand.
#5 Call Your Internet Service Provider or Web Host
The next step is to contact your Internet service provider (ISP) (or hosting provider, if you don’t run your Web server) and request assistance.
Keep your ISP or hosting provider’s emergency phone numbers on hand so you can swiftly call them in the event of a problem. There are several factors to consider when determining whether or not an Internet service provider (ISP) or web host has previously identified an assault.
