The possible attacks
There are multiple kinds of attacks that can be put into action. The main kinds are as follows:
- Denial of Service
- 0-day
- Brute force
- Advanced Persistent Threat
- Automated exploitation tools
- ISP intercept
- Supply chain attack
- Social engineering
- Hypervisor Breakout
Denial of Service
A Denial of Service (DoS) attack is an attack that aims to make some service unavailable. In the last few years, usually we speak about DDoS, since those are very effective and cheap and for those reasons have become the most used DoS attack. DDoS attacks consist in multiple machines trying to overload a server or its connection to make the services that are running on that server unavailable.
The good part about DoS attacks is that in majority of the cases, as soon as they end it, all is back to normal. When this is not true, small actions have to be executed by system administrators, such as restarting a service or rebooting a machine.
Note
There is no way to completely protect a server from a DoS attack...
