Question: What exactly is keylogger software, and how can we avoid this type of security breach with our computer systems?

The software records the keystrokes that a device user hits, and puts that information to nefarious use. Hackers may enter your system through the following means: The primary problem is that the malware is usually added without the user even knowing. But once the hackers have access to your system, they can cause all sorts of trouble for you and your organization. Best bet: Alert staff to these potential modes of entry, and train individuals to avoid these scenarios and report anything suspicious, for instance, if they open an email attachment that they initially think is from a valid sender. Also, protect your system with up-to-date virus software.
