Cybersecurity is one of the most important parts of today’s life. Almost all of us have different problems nowadays regarding Cyber Security. The scams online have also been increased in the last few years. Many people have faced bankruptcy in the last few years. Hence, it has become a serious concern for the people of today’s world.
Hence, in this article today, we are going to point out a few of the most common cybersecurity threats and, we will also tell you about how you can fight them. Check out these tips below:
TCP SYN flood attack
Exploiters attack the buffer space during TCP aka Transmission Control Protocol session initialization handshake. The attacker will flood your device with a small in-process queue with different connection requests, but will not respond if you reply to those requests. This makes your system crash as it waits for the response from the attacker’s device.
To keep yourself safe, you can:
- Place servers behind a firewall to stop the inbound SYN system.
- Increase the connection queue size and decrease the timeout with an open connection.
Teardrop attacks
This attack causes length and fragmentation offset fields in sequential IP packets to overlap one another on the attacked host overall. The attacked hosts in the meantime will try to reconstruct these packets; however, they fail miserably. This way, the target system gets confused and starts crashing.
To keep yourself safe, you can:
- Install patches to protect against this DoS attack
- Or, if you don’t have these patches, you can disable the SMBv2 and block ports 139 and 445.
Smurf attack
These attacks involve IP spoofing ICMP to confuse the target network with traffic. This attack uses ICMP echo requests targeted at the broadcast IP address. These ICMP requests will originate from a spoofed victim address. For example, if the target address is 10.0.0.10, the attacker will spoof an ICMP echo request from the target address to broadcast address 10.255.255.255. This request will go to all the IPs in range with the requests going back to the former address, i.e. 10.0.0.10. And thus, will overwhelm the network. This process is going to be repeatable and will generate a huge amount of network congestion, causing the address to crash.
To keep yourself safe, you can:
- Disable IP-broadcasts at the routers. This will help you prevent the ICMP echo broadcast request to every network device.
- Also, configure these end systems to prevent them from responding to the ICMP packets from the broadcast address.
Ping of death attack
This attack uses IP packets to ping a target system with an IP size over a maximum of 65,535 bytes. IP packets of this huge size are not allowed. Hence the attackers opt to fragment them. Once the target system reassembles the packet, it starts to buffer overflow. Then it comes back to the same old story, where the system ultimately crashes.
To keep yourself safe, you can:
- Block this attack using a firewall that is going to check the fragmented IP packets of maximum size.
