Alibaba Cloud Elastic Compute Service (ECS) provides a faster and more powerful way to run your cloud applications as compared with traditional physical servers. You can achieve great results on your cloud needs. With ECS, you can achieve more with the latest generation of CPUs as well as protect your instance from DDoS and Trojan attacks.
In this tutorial, we will talk about the best practices for provisioning your Ubuntu 16.04 server hosted on an Alibaba Cloud Elastic Compute Service (ECS) instance.
Ubuntu 16.04 comes with a default interface for interacting with IP tables known as UFW (Uncomplicated Firewall). UFW is a simplified tool which aims towards simplifying the process of setting up IP tables especially for beginners who are new to the Linux environment.
UFW is a right choice for adding another security to your Ubuntu 16.04 server running on Alibaba Cloud.
In this article, you will get some information on the importance of IoT device security by looking at CERT's interpretation of the infamous 2016 DDoS attack.
Dyn said that this DDoS attack involved tens of millions IP addresses, most of which were IoT and smart devices. Dyn believed that the attack came from a malicious code named "Mirai." Hacker organizations NewWorldHackers and Anonymous claimed responsibility for the attack .
In DDoS attacks (including Mirai) targeted at IoT devices, attackers perform brute-force cracking on popular password files through the Telnet port, or log on using the default password. If attackers successfully log on through Telnet, they attempt to use the necessary embedded tools like BusyBox and wget to download the bot of the DDoS function, modify executable attributes, and run and control IoT devices. Due to the difference of the CPU command architectures, after determining the system architecture, some botnets can select samples of the MIPS, arm, or x86 architectures for downloading. After running these samples, botnets receive related attacks commands to initiate attacks.
In this article, you will get some information on the analysis of scanning and intrusion script for DockerKiller Threat.
Once Docker is compromised and auto.sh is executed, earlier versions of malicious files, if any, are removed, and then updated files are downloaded from the server to the compromised server, including the webshell, mining program, backdoor program, task files, and mining configuration files, and proceeds to their execution.
The sequence of the attack is as follows:
When you use Anti-DDoS Pro to protect your site, we recommend that you add back-to-origin CIDR blocks to the whitelist so that traffic from Anti-DDoS Pro is not mistakenly blocked by security software on your origin server.
This tutorial explains a simple setup and verification process of Anti-DDoS Pro non-website protection through the Alibaba Cloud console. It does not cover all possible options.
Anti-DDoS Pro is a value-added service used to protect servers, including external servers hosted in Mainland China, against volumetric DDoS attacks. You can redirect attack traffic to Anti-DDoS Pro to ensure the stability and availability of origin sites.
Alibaba Cloud Anti-DDoS Premium is a value-added DDoS protection service. This service is used to protect servers against volumetric DDoS attacks and ensure the availability of business. By modifiying DNS records to redirect malicious traffic through Anti-DDoS Premium’s dedicated IP address, Anti-DDoS Premium, protects your online presence.
Alibaba Cloud Anti-DDoS Premium is a value-added DDoS protection service. This service is used to protect servers against volumetric DDoS attacks and ensure the availability of business.
In this demo, you will learn the benefits of using Anti-DDoS premium and also you will see a step by step demo about how to setup Anti-DDoS premium service in just a few seconds.
