Protect us from DDoS attacks

WHY PROTECT US FROM DDOS ATTACKS?

Nowadays it is easy to find in the news, almost every day, Internet references, banks, forums and websites that have stopped working for a few hours to recover after a short time, stating that they have suffered a hacker attack, usually the most common of them: a DDoS attack, one of the most used to stop the operation of an Internet service and attract attention, but what is really a DDoS attack? How does it affect the server, and what effects can it cause?

A DoS or DDoS attack (depending on how it is carried out) is nothing more than an unusually large number of requests to an IP address. This is so that the server is unable to manage such requests causing an error in the system and stopping or restarting the service, leaving your website inaccessible to other users.

Now, a simpler example, imagine a hospital, (our server) where hundreds of users (applications) arrive at the emergency room, however the hospital no longer has more doctors available and its infrastructure does not allow one more patient. The result: the hospital collapses, cannot provide an acceptable service and closes its doors until it can be re-established and reopened. The same goes for DDoS attacks, it creates a huge flow of messages and requests that are thrown at the target so that it is overloaded and forced to close; as a result, the service is denied to the real users.

 

BUT HOW DO DDOS ATTACKS WORK?

The DDoS attacks first infect a Trojan with other innocent computers called slaves, which receive the Trojan through spam, emails, visits to certain undesirable web pages, etc. The Trojan acts without the victim noticing.

When the hacker orders it, this network of slave computers, called a botnet, performs a coordinated attack, all at the same time. It is not an aggression in itself that is why it is difficult to detect, because these computers ask for an access to the service, or send a data, or another apparently innocuous activity. But by doing so all at the same time they congest the system and end up blocking it.

Be it for whatever reason: political, economic, or simple a   personal purpose, a DDoS attack can be directed to any type of host connected to the Internet. Be it the systems of a government, those of a company, a video game platform, or even a simple blog. The three most common attacks are:

 

Based on volume: in this case the purpose of the attack is to saturate the bandwidth of a website that is the target. The idea is to cause congestion.

 

Protocol attacks: this type of attack consumes server resources or some service that works as an intermediary, such as a firewall or load balance. This attack can knock down services that are capable of maintaining millions of active connections in a stable manner.

Application layer attacks: this uses requests that are disguised as legitimate or innocent users but in order to make the web server stop working.

 

HOW TO DETECT AN IMMINENT ATTACK?

While there are service interruptions that do not necessarily occur due to hacker attacks, there are some symptoms to consider for identifying a denial of service attack. If the network was running much slower than usual, the websites were not available, or if you received a huge amount of spam, you could be under a denial of service attack. You must notify your network operations staff of your suspicions.
