How would you respond to the following discussion posting?

• How do you remove a key logger?
• What is the difference between black box testing and white box testing?
• What can you do to prevent a port scan?

Keylogger is a piece of software that is installed and can record a user's keystroke on a keyboard,

which then saves the information. Additionally, keyloggers can collect information from computers, laptops, smartphones and other mobile devices. An interesting fact about this type of software is that it is both legal and illegal to use. When it comes to removing a keylogger, it is best to do so as soon as possible. One of the best ways to remove this type of software is to use an anti-virus/anti-malware software to detect and eliminate the software. Additionally, you can run another program that will run a full system scan and attempt to fix any of the damages that were caused by the keylogger (Torres, 2017).

When it comes to black box testing and white box testing, the biggest difference between the two is whether the tester knows any information about the subject being tested. An example of this would be, for white box testing, a tester knowing what the topology of a network is before gaining access. Additionally, black box testing is used for a much higher level of testing (Differences, n.d.).

Port scans occur when a user uses a tool like Nmap, which is a free port scanner, to see what ports are open on a targeted system. So, the best way to prevent a port scan is to have all the open ports blocked or shut down. Additionally, if the security team wanted to go all out, they could utilize their firewalls to redirect those open ports to honeypots (Badrick, 2019).
