DOS/DDOS Mitigation
About
DOS and DDOS attacks often lead to partial or complete disruption of services or service interruptions for institutions and organizations. DOS and DDOS protection systems are multi-layered and dynamic mechanisms that continuously learn and assess network traffic, block malicious traffic, and actively protect by allowing harmless traffic through behavioural modelling.
Main Types of DDOS Attacks
- Network Level
- YReflective/Amplified
- Fragmentation
- Application Specific
- Crafted
The TR7 ASP DOS/DDOS Mitigation can provide protection against commonly known attacks such as ICMP Smurf Attack, SYN Flood, Tear Drop, UDP Flood, NTP Flood, DNS Flood, Zero Byte UDP, Protocol Validation, PUSH Floods and ACK Floods, Possible WAREZ Attack, Camfrog, TCP Ack, Ping of Death ICMP, Null Flood, Christmas Tree, Port Scan, SMBnuke, Pepsi, Fraggle Attack, Zombie TCP and Smurf Attack.
IP addresses detected in an attack are quarantined for a specified period and can be monitored on the DOS/DDOS Mitigation Dashboard.
How to Configure?
To configure DOS/DDOS Mitigation for the relevant network, follow the steps through the TR7 ASP web interface Network > DOS/DDOS Mitigation.
Interface
DOS/DDOS Mitigation Screen
By following the steps "Network > DOS/DDOS Mitigation" you can find the types of attacks against which protection will be provided on the TR7 ASP device.
