How to Defend Against a DDoS Attack | Total Security Software

Cybercrime is growing dramatically in today's tech world. Hackers exploit the personal information of Internet users to their advantage. They dive into the dark web to buy and sell illegal products and services, and they even have access to classified government information.

Cybercrime is at an all-time high, costing businesses and individuals billions every year. The evolution of technology and the increasing accessibility of smart technologies will not help in the future. As law enforcement attempts to tackle the growing problem, the number of criminals continues to grow, taking advantage of the anonymity of the Internet.

What is Cybercrime?

Cybercrime is defined as a crime when a computer is the object of the crime or is used as a tool to commit an offense. A cybercriminal can use a device to gain access to a user's personal information, confidential business or government information, or to deactivate a device.

Cybercrimes fall into two categories:

• Crimes targeting networks or devices (viruses, malware, Dos attacks)
• Crimes using devices to participate in criminal activity ( phishing, cyber-harassment, identity theft)

What is a DDoS attack?

DDoS attacks are used to make an online service unavailable and destroy the network by flooding the site with traffic from various sources. Large networks of infected devices called botnets are created by depositing malware on users' computers. The cybercriminal then hacks the system when the network is down.

How to Protect Yourself and Prevent a DDoS Attack?

1. Back to basics

Simple things like bandwidth buffering can allow traffic spikes, including those from a DDoS attack, and give you time to recognize and respond to the attack.

Implement other basic protections to save you time, too: limit your router's throughput, add filters to eliminate spoofed or malformed packets, and set lower drop thresholds for ICMP, SYN, and flooding. UDP. All of this will save you time trying to find help.

2. Planning DDoS responses

When a DDoS attack is confirmed, put in place a response plan.

• Contact the relevant members of your response team.
• Contact your ISP, but don't be surprised if they block your traffic. It may offer you to divert your traffic through a third-party cleansing network.

3. Prioritize and sacrifice to survive

Make sure that the available network resources are prioritized.

Sacrifice low-value traffic to keep high-value applications and services alive.

This is the kind of thing that should be in your response plan so that these decisions are not made on the fly and under pressure. List your most trusted partners and external employees using VPN to make sure they get priority.

4. Multi-vector attacks

Multiple vector attacks, such as when a DDoS attack is used to hide another hack, are very difficult to defend.

The hacks behind a DDoS attack do not matter as long as you defend yourself against this attack as a priority. You do this by using a CDN to handle volumetric attacks, with web application firewalls and gateway devices doing the rest. A specialist in defense against DDoS attacks will be able to advise you.

5. DDoS Attack Mitigation Services

If you are likely to be the target of a DDoS attack (for example, if you are a large corporation), it is wise to invest in DDoS attack mitigation services.
