What Is A DDoS Attacks

A DDoS attacks is a type of cybercrime in which the perpetrator aims to flood the server with traffic to prevent the user from accessing the site or services. The intent of this kind of attack is a personal vendetta, fun, or financial gain. When the financial gain is the motive, it hinders users from accessing the website and as a result, using the competitor’s website. At times, it is also carried out to ask for a ransom.

It’s no secret that DDoS attacks are on the rise, and the latest occurred on AWS (Amazon Web Service) in February 2020, two years after GitHub.

IoT and work from home are on the rise, increasing the susceptibility to DDoS attacks. Hence, in these times it is important to safeguard your system against these attacks. An Small Business IT Consultant knows about DDoS perfectly and how much they are dangerous for your business.

How DDoS Attacks Function

A DDoS attack aims to generate a lot of traffic on a particular server, making it inaccessible to authentic users.

The DDoS attack is a form of denial-of-service (DoS). In DoS, a single connection is bombard with a fraudulent request.

Botnets are the means DDoS is implemented. The hacker will install a malicious code or software in the device called a botnet which shall barrage the server with incessant traffic.

How to Identify a DDoS Attack

As the DDoS attack symptoms match the signs of daily glitches like the sluggish performance of the website, low download speed, etc., detecting them is difficult. These attacks may vary based on the period or the degree of ill effect.

Types of DDoS attack

You can categorize DDoS attacks as follows:

DNS amplification is a volume-based attack. A fake address is sent to the DNS server with a DNS request using the fake address. DNS responses are amplified.

Using Layer 3 and 4 of the OSI protocol stack, a protocol attack compromises the entire system.

Application-Layer Attacks: This type of attack intends to overwhelm the target’s resources. This type attacks the application layer which generates a response to Hypertext Transfer Protocol (HTTP) requests.

How To Prevent and Mitigate DDoS Attacks?

As the signs of DDoS attacks are very similar to the symptoms we encounter often, pinning them down is a little tricky. However, once an attack is detect the ways you can fix them include:

Risk Assessment: Risk assessment is a practice every organization must undertake. Regularly conducting them lets you know the strengths and shortcomings of the organization. Once all weaknesses are known, you would have a picture of how to tackle DDoS attacks.

Traffic Fragmentation: Once you suffer from a DDoS attack, shutting down the traffic completely is not a viable option. However, a suggested means is to distribute them across servers to make them manageable.

Black Hole Routing: In this strategy, redirect the traffic to a black hole. However, it is important to note all traffic, including bad and good is redirect to a black hole.

Rate Limiting: Another strategy is to reduce the magnitude of requests a server can accept in a time frame. Though it is not adept in warding off a robust attack but is a feasible approach.

Firewalls: A web Application Firewall (WAF) is a layer between the internet and the company’s server. They can then specify the rules and see the pattern of traffic.
