Let us learn the prevention and protection from DoS or DDoS Attack.
A Denial-of-Service (DoS) attack is a cyber attack that attempts to keep the users of a device or network from using that device or network by overwhelming them with malicious traffic.
Steps to avoid DoS or DDoS Attack :
Regularly keep your software up to date and regularly update your security software, operating system and applications.
Security update help us to mend or cover vulnerability in the network system that the hacker or the attacker may tried to exploit.
Apply router filter to avoid the exposure to certain DoS or DDoS attack, if such filters are available for your system install patches to guard against SYN flooding attack.
Disable any unusual or unwanted network service attack, so as to reduce the ability of attacker to take advantage of the exposed service to attack.
Use firewalls and intrusion detection system which act as traffic scanning barriers between the network systems.
Use anti-DoS or DDoS hardware and software, use of the anti-DoS or DDoS hardware and software help to detect and reduce the DoS attack.
Regularly inspect your physical security with current new security requirements.
Maintain the appropriate strong passwords, especially access to higher confidential accounts and data, such as UNIX Root or MS Windows.
Avoid clicking on suspicious links or downloading attachments from the unknown source which may be harmful malware.
Monitor network traffic to detect any unusual pattern and take immediate action to prevent from the DoS or DDoS attack.
