What Are DoS and DDoS Attacks in Cyber Security?

DoS attacks are those where the hackers flood a network or system with heavy traffic. The system or the network is crashed or shut down, and becomes inaccessible to the users. 

Mostly, the DoS attacks are carried out on the servers of companies in various industries, like banks, IT firms, eCommerce, government, media portals, etc. While DoS attacks don’t cause data loss or financial breach, but it costs time and money to tackle such attacks. 

DDoS attacks are those where the hackers flood a server or network with heavy traffic from several machines or computers. In DDoS attacks, hackers use numerous exploited systems as a source of flooding the target. It prevents the intended users from accessing the network or server. 

DoS attacks are of two types: flooding and crashing.

• Flooding is when the targeted server or system gets plenty of traffic that can’t be handled. It results in slowing down the server or completely shutting it down. 

• Crashing is when the vulnerabilities in the target source are exploited to crash it. When the server is crashed, it becomes inaccessible to the intended users.

DRDoS attacks are those where the hackers hide their own identity and use third parties to flood the server with traffic. DRDoS is used because it is an anonymous type of attack, where the victim servers are reflected as the cause of the attack. 

Performing DoS/DDoS on Mobiles

• Use intrusion detection and protection systems.

• Install reputed antivirus and antispyware software on all the computers.

• Use reverse DNS lookup to find and verify the source of traffic.

• Implement strong security practices on all devices and servers.

• Use ingress, egress, and address filters on external firewalls.
