Best Botnet Detection Software

Botnets are fleets of unwitting devices hijacked by hackers and ordered to access websites and Web services simultaneously.

Although the primary use of these annoying devices is to overwhelm the servers of targeted websites, they can also be used for click fraud, artificially padding the bill of pay-per-click customers.

However, the bots are used, they are tough to shut down. However, there are several techniques that you can use to combat this problem and keep your website available to legitimate visitors. To implement these strategies, you need the right tools.

Here is our list of the seven best botnet detection software:

Botnet detection software

You want to stop them from overloading your resources rather than just spotting botnets. There are several ways this can be done. Probably the most effective tactic is to get a vast capacity server to take the hit and just pass on the actual traffic to your Web server. There are other methods available, such as blacklists, honeypots, and black holes.

As there are several angles you can use to detect and block botnet activities, we have identified various solutions that include onsite options and edge services.

The best botnet detection software

Botnet detection requires network traffic analysis for incoming connection requests to Web servers and load balancers.

What should you look for in a botnet detection system? 

We reviewed the market for botnet detection software and analyzed the options based on the following criteria:

  • A system that can catch DDoS attacks before they block access to a Web server
  • A software package that offers security services in addition to botnet detection
  • A service that can take remediation action to reduce the effects of a botnet attack
  • Threat intelligence that includes an IP address blacklist
  • Quick detection and response
  • A free trial or a money-back guarantee for a no-risk assessment period
  • A good deal that provides valuable services for a reasonable price

As well as working to our selection criteria, we looked for a range of solutions that offer options for hosted and on-premises packages and include subscription services and software packages that can be bought outright.

1. SolarWinds Security Event Manager (EDITOR’S CHOICE)

SolarWinds Security Event Manager

SolarWinds Security Event Manager is a protection system for networks. The service operates on your site as a virtual appliance, installed on top of either VMWare or Hyper-V. This isolates the system from any potential threats circulating on the network, making it hard to tamper with.

The botnet detection systems and defense strategies in the Security Event Manager are focused on protecting the network – as it operates within the network, it cannot intercept traffic before it arrives on site. However, it able to block traffic as soon as it arrives.

SolarWinds supplies all installations of the Security Event Manager with a feed of community-sourced IP addresses found to be the sources of malicious activity. This blacklist saves time examining packet contents – if the address is on the list, that packet just isn’t getting in.

The Security Event Manager updates firewall tables with its blacklist, putting botnet blockers right on the network’s boundary. Any action the firewall takes to block traffic gets logged, and those logs are all picked up by the Security Event Manager. The security system is a SIEM. It collects and consolidates log messages. The threat hunter then scours through log messages, which will spot the block on a request. This then gets reported in the dashboard. The notification from the firewall gets passed through to a log file and stored.

The logs that the Security Event Manager saves are all preserved and made available for standards compliance auditing. This log management function makes the Security Event Manager a good choice for businesses that need to follow PCI DSS, GLBA, SOX, NERC CIP, HIPAA. The log manager includes a file integrity monitor that protects log files from tampering.

SolarWinds offers the Security Event Manager for a 30-day free trial.

As with the SolarWinds option, this is a network resident solution. It can communicate with firewalls to push its detection capabilities right to the edge of the network. However, it is primarily a network defense system.

The dashboard for the NetFlow Analyzer includes attractive dials and graphs that show live traffic patterns. The system offers an overview of network activity, and it also provides traffic shaping measures. These allow you to throttle certain types of traffic and prioritize or block specific applications. This tool could be used to shut down a botnet attack by closing off all services to connection requests temporarily. However, a more targeted approach would be to update the firewall table to block the IP addresses of the source of suspicious activity.

The ManageEngine NetFlow Analyzer allows you the flexibility to choose a strategy to deal with botnet activity. The dashboard of the service is customizable as well. This tool would save you money on your botnet detection strategy because it can help you with general network traffic management and squeeze value out of your existing network infrastructure.
