How to secure from DDoS Attack

Introduction of DDoS Attack :

A distributed denial-of-service (DDoS) attack operates as its name implies; it’s a form of cyber attack that disrupts connectivity or network services to deny service to users. Attacks generally feature tools, such as a bot, that overwhelm the network with repeated signals until it can no longer process genuine requests from users.

In which multiple compromised computer systems attack a target, such as a server, website, or another network resource, and cause a denial of service for users of the targeted resource. service may include email, online accounts (e.g.., banking), or other services.

Basically 3 common types of DDoS attacks:

The following are:

  1. Volumetric attacks

2. Protocol attacks

3. Application-layer attacks

1. Volumetric attacks: The volumetric attacks flood a machine’s or a network’s bandwidth with false data requests on every available port. This overwhelms the network, leaving it unable to accept its regular traffic. There are subcategories of volumetric attacks as well.

2. Protocol attacks: Protocol attacks target the protocols used in transferring data to crash a system.

3. Application-layer attacks: Similar to protocol attacks, application attacks target weaknesses in an application.

These attacks focus primarily on direct web traffic and can be hard to catch, because a machine may think it’s dealing with nothing more than a particularly high level of Internet traffic.

Various types of ways to secure a DDoS attack :

a. Identify Warning Signs of a DDoS Attack

b. Secure your Infrastructure with DDoS Attack Prevention Solutions

c. Know your network’s traffic

d. Know the symptoms of an attack

e. Have a DDoS Plan

f. Protect your Network

g. Define a Specific Team

h. Update Everything Regularly

Identify Warning Signs of a DDoS Attack: If you can identify the symptoms of a DDoS attack as early as possible, you can take action and hopefully mitigate damage. Spotty connectivity, slow performance, and intermittent web crashes are all signs that your business may be coming under attack from a DDoS criminal.

b. Secure your Infrastructure with DDoS Attack Prevention Solutions: Equip your network, applications, and infrastructure with multi-level protection strategies. This may include prevention management systems that combine firewalls,

VPN, anti-spam, content filtering, and other security layers to monitor activities and identity traffic inconsistencies that may be symptoms of DDoS attacks.

Know your network’s traffic: Every organization’s infrastructure has typical Internet traffic patterns — know yours. When you understand your organization’s normal traffic pattern, you’ll have a baseline.

Know the symptoms of an attack :

Your network slows down inexplicably. The website shuts down. All of a sudden, you’re getting a lot of spam.

These can all be signs of a DDoS attack. If so, the organization should investigate.
