Bots and botnets have become a significant worry for many organizations, including government offices.
A bot is a computer that has been infected with malware and has particular malicious tools installed so it can attack other computers as coordinated by a hacker. Botnets — worldwide networks of bots — are utilized each day in different kinds of attacks, from compromising other computers to generating phishing messages and committing financial fraud.
Keeping bots out of your condition can be challenging, however, the means are straightforward.
Mitigating vulnerabilities, for example, will incredibly reduce the opportunities for hackers to compromise an organization's computers. Organizations ought to likewise consider adding other security controls to supplement antivirus software, for example, intrusion prevention systems, firewalls, content filtering and inspection technologies (spam filtering and web content filtering, for instance), and application whitelisting.
Remember about the "soft" side of prevention — having strategies that address malware prevention and implementing a viable mindfulness program that causes users to understand how to avoid malware infections. Many malware infections prevail by preying on users' slip-ups, not by specialized vulnerabilities in the computers they at last infect.
A particular sort of intrusion prevention system known as network behavior investigation (NBA) can distinguish unordinary network traffic designs, for example, those produced by bots attacking other computers. On the off chance that a few computers have been transformed into bots, an NBA system might be very powerful at finding their activity on the network and helping to recognize which computers are influenced.
On the off chance that administrator-level access was gained by the bot software or other malware on the computer, or the malware can't be expelled by ordinary methods, it is enthusiastically suggested that you modify the computer, including reinstalling and securing the operating system and all applications, then restore its data from clean backups. In the event that a computer isn't properly cleaned up after an infection, all things considered, it will be re-infected and turn out to be a piece of another botnet.

1) Prevent Botnet Attack
Traditionally, the most important security control for preventing malware infections is antivirus software. While this is a basic part of stopping bots, without anyone else it's not adequate. Organizations ought to endeavor to eliminate the low-hanging natural product, for example, unpatched operating systems and applications that are not configured securely.Mitigating vulnerabilities, for example, will incredibly reduce the opportunities for hackers to compromise an organization's computers.

2) Identify the Real-Time Botnet Attack
The greater part of similar tools that are suggested for stopping malware, especially antivirus software, intrusion prevention systems, and application whitelisting, are additionally useful for determining when a computer has been infected with a bot or other malware. Antivirus software and intrusion prevention systems are best at identifying known attacks. On the off chance that application whitelisting is properly implemented and monitored, it can distinguish changes to a computer's executables and identify the nearness of obscure new executables — both indications of a potential malware infection.A particular sort of intrusion prevention system known as network behavior investigation (NBA) can distinguish unordinary network traffic designs, for example, those produced by bots attacking other computers.

3) Clean Up Devices that Already Have Infected
After identifying any computers that are infected with bots, the following stage is to disconnect them. Separate them from the networks to keep them from infecting other computers or causing other harm. In a perfect world, cleaning up an infected machine would just involve using antivirus software or a specific bot removal tool to uninstall the malware, just as mitigating the helplessness that was misused to install the bot in any case. Unfortunately, it's increasingly regular that such tools can't uninstall or otherwise expel malware from computers.On the off chance that administrator-level access was gained by the bot software or other malware on the computer, or the malware can't be expelled by ordinary methods, it is enthusiastically suggested that you modify the computer, including reinstalling and securing the operating system and all applications, then restore its data from clean backups.
