Ping Commands'
primary use is to test various points in network connectivity. Unfortunately,
the ping command can be used to attack a network or website. These attacks are
often called Denial of Service (DoS), which overloads a web server by sending
too many ping requests. DoS attacks can slow down the web server, even causing
it to crash (Guru99.com, 2020). These attacks work because the ping command
requires sending small packets of information out to an IP address, which sends
a response back. When thousands of ping commands are sent to one IP address or
a web server, it causes it to slow down or crash due to the vast amount of
bandwidth needed to process the packets being sent.
A computer virus
is a malicious software that infects the computer to spread to other networks
and computers. Symptoms of a computer virus may vary based on the type of
virus. However, common symptoms are unusually slow performance, frequent
crashes, unknown programs, and mass emails being sent from your account
(Fruhlinger, 2019). Protecting your computer is essential and can be done so by
installing antivirus software. Antivirus software has its limitations and can
only stop what viruses are known to the software. Along with antivirus
software, it is vital to keep your Operating System up to date because of virus
attack vulnerabilities in your OS (Fruhlinger, 2019).
Phishing is an
internet scam that attempts to steal sensitive information from users, usually
by email (Vahid et al., 2017). Criminals encourage victims to download or visit
websites that will secretly install malicious software or persuade a user to
enter personal information. Each attack is different and can result in money
lost for a company or a personnel bank account being emptied. It is essential
to remain the causes of phishing attacks when using email. Avoid clicking any
links or downloading any software that may seem suspicious. Phishing attacks
often have poor grammar or unusual email sender. Training is the best way to
identify and circumvent any phishing attacks.
