QUESTION
I am working on an SMS-based service that parses incoming texts and sends a response, building on top of Twilio. I am concerned about a possible ddos which would result in increased costs. Is there a way of preventing this or limiting the number of times a user can send SMS without you being charged? I am based in Australia, so some of the alternatives to Twilio are not available with local numbers.
...ANSWER
Answered 2021-Apr-16 at 17:06You can monitor inbound activity and if you see a massive influx, you can remove the webhook, as detailed here, which will prevent anymore SMS inbound toward your account.
Is there a way to block incoming SMS on my Twilio phone number?
QUESTION
While Azure Event hub can have thousands and million? of messages per second, the Azure IoT hub has a surprisingly low limitation on this.
- S1 has 12 msg/sec speed but allow 400.000 daily msg pr. unit
- S2 has 120 msg/sec speed but allow 6.000.000 daily msg pr. unit
- S3 has 6000 msg/sec speed but allow 300.000.000 daily msg pr unit.
Imagine an IoT solution where your devices normally sends 1 message every hour, but have the ability to activate a short "realtime" mode to send messages every second for about 2 minutes duration.
Example: 10.000 IoT devices:
Let's say 20% of these devices happens to start a realtime mode session simultaneously 4 times a day. (We do not have control over when those are started by individual customers). That is 2000 devices and burst speed needed is then 2000 msg/second.
Daily msg need:
- Normal messages: 10.000dev * 24hours = 240.000 msg/day
- Realtime messages daily count: 2.000dev * 120msg(2 min with 1 msg every second) * 4times a day = 960.000 messages Total daily msg count need: 240.000 + 960000 msg = 1.200.000 msg/day. Needed Azure IoT hub tier: S1 with 3 units gives 1.200.000 msg/day. ($25 * 3units = $75/month)
Burst speed needed:
- 2000 devices sending simultaneously every second for a couple of minutes a few times a day: 2000 msg/second. Needed Azure IoT hub tier: S2 with 17 units gives speed 2040 msg/second. ($250 * 17units = $4250/month) Or go for S3 with 1 unit, which gives speed 6000 msg/second. ($2500/month)
The daily message count requires only a low IoT hub tier due to the modest messages per day count, but the need for burst speed when realtime is activated requires an unproportionally very high IoT hub tier which skyrockets(33 times) the monthly costs for the solution, ruining the businesscase.
Is it possible to allow for temporary burst speeds at varying times during a day as long as the total number of daily messages sent does not surpass current tier max limit?
I understood from an article from 2016 by Nicole Berdy that the throttling on Azure IoT hub is in place to avoid DDOS attacks and misuse. However to be able to simulate realtime mode functionality with Azure IoT hub we need more Event Hub like messages/second speed. Can this be opened up by contacting support or something? Will it help if the whole solution is living inside its own protected network bubble?
Thanks,
...ANSWER
Answered 2021-Apr-07 at 15:31For real-time needs definitely, always consider Azure IoT Edge and double check if it is possible to implement it on your scenario.
In the calculations you did above you refer, for example that S2 has 120 msg/sec speed. That is not fully correct. Let me explain better:
- The throttle for Device-to-cloud sends is applied only if you overpass 120 send operations/sec/unit
- Each message can be up to 256 KB which is the maximum message size.
Therefore, the questions you need to answer to successfully implement your scenario with the lowest cost possible are:
- What is the message size of my devices?
- Do I need to display messages in near-real-time on customer's Cloud Environment, or my concern is the level of detail of the sensors during a specific time?
- When I enable "burst mode" am I leveraging the batch mode of Azure IoT SDK?
To your questions:
Is it possible to allow for temporary burst speeds at varying times during a day as long as the total number of daily messages sent does not surpass current tier max limit?
No, the limits for example to S2 are 120 device-to-cloud send operations/sec/unit.
Can this be opened up by contacting support or something? Will it help if the whole solution is living inside its own protected network bubble?
No, the only exception is when you need to increase the total number of devices plus modules that can be registered to a single IoT Hub for more than 1,000,000. On that case you shall contact Microsoft Support.

QUESTION
The website i scapped blocked me out by showing 406 Not Acceptable on the browser. It might i mistakenly sent too many requests at once on phython code.
So i put time.sleep(10)
for each loop to not make it look like a DDoS attack, and it seems worked out.
My questions are:
How long would it be reasonable to send between each request? Sleep 10 seconds for each loop makes my code running too slow.
How to fix the 406 Not Acceptable error on my browsers? They still block me out, only if i chance my ip address but it's not permanent solution.
Thank you all for your answers and comments. Good day!
...ANSWER
Answered 2021-Mar-30 at 09:21Any rate-limit errors are all subject to which website you choose to scrape / interact with. I could set up a website that only allows you to view it once per day, before throwing HTTP errors at your screen. So to answer your first question, there is no definitive answer. You must test for yourself and see what's the fastest speed you can go, without getting blocked.
However, there is a workaround. If you use proxies, then it's almost impossible to detect and stop the requests from executing, and therefore you will not be hit by any HTTP errors. HOWEVER, JUST BECAUSE YOU CAN, DOESN'T MEAN THAT YOU SHOULD- I am a programmer, not a lawyer. I'm sure there's a rule somewhere that says that spamming a page, even after it tells you to stop, is illegal.
Your second question isn't exactly related to programming, but I will answer it anyways- try clearing your cookies or refreshing your IP (try using a VPN or such). Other than changing your IP or cookies, there's not many more ways that a page can fingerprint you (in order to block you).
QUESTION
I want to create a virtual private network in which I can manage virtual machines's interfaces with iproute2.
For example, with AZ CLI, I create two virtual machines in subnet 172.16.1.0/24, each machine has one interface:
az network vnet create -g test -n net --address-prefix 172.16.0.0/16 --ddos-protection false --vm-protection false
az network vnet subnet create -g test --vnet-name net -n subnet1 --address-prefixes 172.16.1.0/24 --network-security-group test
az network nic create -g test -n vm1-nic --vnet-name net --subnet subnet1 --private-ip-address 172.16.1.10 --public-ip-address vm1-pub
az network nic create -g test -n vm2-nic --vnet-name net --subnet subnet1 --private-ip-address 172.16.1.11 --public-ip-address vm2-pub
az vm create -g test -n vm1 --image rhel --size Standard_F4 --generate-ssh-keys --nics vm1-nic
az vm create -g test -n vm2 --image rhel --size Standard_F4 --generate-ssh-keys --nics vm2-nic
Then I connect on vm1 with ssh, ping 172.16.1.11 should work.
It is possible to change vm's network interfaces ip addresses with iproute2 command? Like I put 10.100.0.1/24 on vm1's interface and 10.100.0.2/24 on vm2's interface with iprout2 command and I ping to 10.100.0.2 from 10.100.0.1.
I want to understand how virtual machines are connected, the connection is simulated as a wired connection which we can configure network interfaces?
...ANSWER
Answered 2021-Mar-24 at 02:19See the description for the static IP address here:
If you manually set the private IP address within the operating system, make sure it matches the private IP address assigned to the Azure network interface. Otherwise, you can lose connectivity to the VM.
It means if you want to change the IP address within the VM, you need first to change the configuration of the VM NIC in Azure, then you can change the IP address within the VM using the command. If not, you can't change it. Generally, all the things of the VM are configured by Azure.
QUESTION
Multer has a couple of optional parameters and I understand some of them. But my understanding is a bit unclear for:
- fieldNameSize (is this just the size of field name in req.body or req.file?)
- fieldSize (same as (1) but the field value instead?)
- fields (is this just other fields in body?)
- parts (no idea what this is)
- headerPairs (like Bearer auth token header?)
One last thing. Points 3,4 have a limit of infinity by default. Would it be prudent to set some other limit? How do I determine what to set those to prevent DDOS.
Thanks!
...ANSWER
Answered 2021-Mar-15 at 15:19The limits object specifies the size limits of the following optional properties:
- fieldNameSize — maximum field name size. Defaults to 100 bytes
- fieldSize — maximum field value size. Defaults to 1MB
- fields — the maximum number of non-file fields. Defaults to Infinity
- fileSize — maximum file size in bytes. Defaults to Infinity
- files — maximum of file fields. Defaults to Infinity
- parts — the maximum number of parts (fields and files). Defaults to Infinity
- headerPairs — the maximum number of header key-value pairs to parse. Defaults to 2000.
On how to prevent DDOS, the main setting to focus on would be fileSize
. A large file upload would make it very easy to overwhelm your server.
The rest of the setting is kind of optional, depending on the needs of your project. However, it is a good idea to set to something small like 100
for those that default to infinity.
QUESTION
I'm looking to use annotations like below for rate limiting for DDOS protection
...ANSWER
Answered 2021-Mar-10 at 05:30Nginx ingress uses the A leaky bucket, FIFO queue
for the rate-limiting.
Nginx ingress has some limitations like :
- Requests are counted by client IP, which is not accurate. Not much useful when you want rate-limiting by user identity.
- It is not easy to monitor rejected requests
By using this you can stop a certain amount of requests it's not accurate you can try with POC.
There is one nice article on rate limiting with Nginx : https://medium.com/titansoft-engineering/rate-limiting-for-your-kubernetes-applications-with-nginx-ingress-2e32721f7f57#:~:text=When%20we%20use%20NGINX%20ingress,configure%20rate%20limits%20with%20annotations.&text=As%20an%20example%20above%2C%20the,qps)%20on%20the%20Hello%20service.
QUESTION
Recently I am using pktgen to construct a tool for sending network packets to simulate DDoS attacks.The script I currently write can use four ports to send four different types of network packets. The code is as follows
...ANSWER
Answered 2021-Mar-02 at 07:36Yes, you can generate a range of packets TCP/UDP/NON-IP/SCTP with a single physical NIC port. To do the same follow the steps as
- create VF ports equal to the various ranges (in your use case 2, that is TCP and UDP).
- Insmod with either vfdio-pci or igb_uio
- pass the ports to pktgen as 2 DPDK ports.
- in
main page
set the rate to 50% withset all rate 50
- Use the
range page
to set TCP for port 0 and UDP for port 1.
