As bots are legitimate internet devices, identifying a DDoS attack is tough

Protection against cybercrime
Cybercriminals orchestrate malware, ransomware, phishing, DDoS attacks, identity theft, etc. to steal valuable data or money. Fortunately, we can adapt best practices to protect ourselves from malicious actors. The first line of defence is using antivirus and other security solutions that provide us visibility at Wirespeed. Updating operating system and software, using strong passwords, not opening attachments in the spam mailbox, refraining from accessing or giving out personal data on untrusted websites and keeping a strict vigil on bank statements can protect us.
Safeguarding the vulnerability of computers
Cybercriminals infect computers with viruses and malware to cause disruptions in enterprise operations, damage to the network, steal or delete data. The number of cyberattacks in India stood at 6,07,220 up to June 2021. Though we can’t stop these attacks but can arm ourselves with preventive measures to protect against them. The foremost defense mechanism is installing a firewall to block any brute force attacks on computers. The second line of defense comprises deploying network detection and response tools. Keeping software and systems updated helps prevent malicious actors from exploiting the vulnerabilities. Ensuring endpoint protection allows enterprises to prevent attacks from devices that are remotely connected to the network.
Solutions to prevent Distributed DoS attacks (DDoS)
Identifying a DDoS attack is a tough task for security teams as the bots are legitimate internet devices. However, certain indications include a spike in traffic originating from a single IP address, an unexpected amount of requests to access a single page or endpoint, etc.
To secure the network from these attacks, three fundamental principles have to be followed; identify, defend and respond. Deploying Network Detection and Response (NDR) solutions that monitor networks 24*7 allow security teams to identify any activity outside the normal parameters in real-time. Once the attack has been detected, NDR solutions ensure that the network is defended properly and prompt security teams with the appropriate course of action. Network Forensic tools can be used to analyse the attack and learn the vulnerable spots in the network. Other measures include installing a firewall, creating a blackhole to channel traffic into that route.
Approach to the current situation
Traditional approaches can no longer be adopted to tackle these sophisticated cyberattacks. Malicious actors need to be dealt with using state-of-the-art security solutions that use Artificial Intelligence and Machine Learning to create cyber situational awareness. NDR solutions need to be deployed to ensure network visibility in real-time and network forensics should be performed to analyse the loopholes.
