    • Circumvention of passwords
    • DDoS attacks
    • Phishing attacks.
    • Email spoofing.



    We have listed some/ major computer security threats we face every day, let's proceed to know each one of these threats and solutions to countermeasure them.

    DDoS Attack

    DDoS (Distributed Denial Of Service) attack involves a malicious user using several zombie computers to sabotage/ destroy a website or server. 

    This is easily done when a malicious user sends traffics to a computer /server over and over again, this increases traffic and thereby causing the website to slow, thereafter, crashing the server or website.

    Computer security threats and solutions DDoS

    It is also possible for your computer to be used to perform these attacks. These can be done when a malicious user takes advantage of your computer vulnerabilities to 'distribute' these attacks or spam emails since this is a 'distribution' process, your computer can also be used to perform DDoS attacks.

    • Subduing of data.


    Email Spoofing


    Email spoofing is an act of sending a forged email to an individual. This is done by changing the MAIL FROM of an email to the spoofed email.



    common computer threat email spoofing




    For example.Alice's computer is being infected and Bob and Charlie's email addresses are collected from Alice's computer, the Malware is used to send a spoofed email to Charlie thinking the messages was from Bob.
