The Phishing and DDoS or denial of service attacks are different types of security breaches similar to attacks using viruses, spyware and other malware which generally arrives through email. The cybercriminals often send bogus but impressive and convincing emails to the employees or a specific employee of an organization. The email often appears as an authentic and urgent communication from a reliable executive with urgent request to send organizations records or username and password or other sensitive and confidential data of the organization. Either because of ignorance or hasting to fulfil the request if the employee emails back to the cybercriminals, he or she puts the organization exposed to issues of a security breach.

When DDoS attacks are performed, the organizations who have been doing prosperous business, they will not be able to access their website which will eventually hamper their business.
