This blog post will answer the question, Can a ddos attack be prevented? It will also cover best methods to prevent a DDOS attack. It outlines how DDOS attacks happen and the damage such attacks can cause.This article also talks about the preventative measures that can be taken to avoid DDOS attacks from happening.
Can a ddos attack be prevented?
Yes a DDOS attack can be prevented. DDOS attack is a distributed denial of service attack that can cause grave damage to a network’s infrastructure. DDoS attack is a malicious attempt to disrupt normal functioning of a server, service or a network.
Malicious actors use a combination of multiple connected online devices(botnets) to direct traffic towards the victims network to overwhelm the network’s maximum bandwidth, resulting in breakdown of all normal services.
DDoS is a simple yet very powerful and an effective method to damage network resources of an organization. It is fueled by less secure devices and bad digital habits of careless people.
DDos attacks are incredibly difficult to prevent and mitigate, considering its distributed nature and the huge number of devices that are involved in carrying such an attack.
Cybercriminals exploit less secure devices including computers, mobile phones, and other IOT devices by infecting them with malware. Each individual infected device is called bots or zombies. These infected devices form an interconnected network called botnets.
The malware installed in these devices allows the hacker to control these botnets remotely. Once a huge network of zombies is established the attacker is able to direct traffic to the victims server by utilizing individual devices’ resources.
When a specific victim has been targeted by the botnet, it sends continuous requests to the target IP address, potentially overwhelming the server or network and disrupting its normal service causing a denial-of-service to its legitimate end users.
Since each bot in a botnet is a legitimate internet device, it’s extremely strenuous to differentiate attack traffic and normal traffic.
Attackers perform these attacks directly or through reflection. Reflection makes it more difficult to track down the source of the attack and makes it more difficult for the DDoS handling systems by bouncing packets off other hosts.
There are many tried and tested methods or mechanisms to prevent DDOS attacks on your organization. These are the few things to keep in mind that can help prevent DDOS attacks.
Develop a DDoS Attack Response Plan. Do not be caught blind to DDoS attacks; have a good response system in case of security breaches so that your organization can respond as quickly as possible.
Your plan should document how you maintain business operations if a DDoS attack is successful, any technical and technical skills that will be required, as well as a checklist of programs to ensure that your assets receive significant threats.
Additionally, set up an incident response team in the event of DDoS success and define responsibilities, such as informing key stakeholders and ensuring communication across the organization.
Protect your infrastructure with DDoS Attack Prevention Solutions. Equip your network, applications, and infrastructure with multi-level security strategies. This may include blocking systems that include security walls, VPN, anti-spam, content filtering and other security layers to monitor activities and traffic identity incompatibility that may be indications of a DDoS attack.
If you want protection through cloud-based solutions, many providers allow advanced security services to incur additional costs. Some options allow businesses to navigate a “full cloud,” entrusting sensitive data to a reputable cloud provider that provides high security protections, both physical and physical.
Perform a Network Risk Assessment. Identify vulnerabilities in your networks before malicious user action. Risk assessment involves identifying security vulnerabilities so that you can integrate your infrastructure to better prepare for a DDoS attack, or for any cybersecurity threats in general.
Testing will protect your network by trying to detect security risks. This is done by taking a list of all network devices, as well as their purpose, system information, and any related risks, and including which devices need to be prepared for future development or testing.
Doing so will help determine your organization’s risk profile so that you can maximize any security investment.
4. Get DDoS Attack Warning Signs. If you can detect the signs of a DDoS attack early, you can take action and hopefully reduce the damage. Spotless connections, slow performance, and occasional web crashes are signs that your business may be under attack by a DDoS hacker.
Educate your team about DDoS attack symptoms so everyone can recognize warning signs.
Not all DDoS attacks are extensive and large-scale; short-term attacks that present a short period of time are equally common. This attack can be very serious because they are more likely to get under the radar as a random incident instead of a potential security breach.
Low-volume DDoS attacks are likely to be malicious software crashes; while your IT security staff is hampered by low volume attacks, malicious software like ransomware could infiltrate your network.
Welcome to cloud-based Service Providers. There are a few extraction benefits to prevent DDoS attacks in the cloud.
Cloud providers that offer high levels of cybersecurity, including security walls and threat management software, can help protect your assets and network from DDoS criminals. The cloud also has greater bandwidth than most private networks, so it is likely to fail if it is under pressure for extended DDoS attacks.
Additionally, reputable cloud providers offer network resuscitation, duplicate copies of your data, systems, and tools so that if your service is damaged or unavailable due to a DDoS attack, you can switch to secure access to backup versions without losing the rhythm.
There are many more things that one can implement in order to prevent a DDOS attack. Staying aware of such attacks and having a response plan is a the one most significant way to protect in case a DDOS attack happens
Conclusion
This blog post addressed the question, Can a ddos attack be prevented? We understood what DDOS attacks are and how they can happen. We also discussed some mechanisms to prevent DDOS attacks. It also outlines the methods one can use to prevent and stop DDOS attacks that can happen to an organization. In this article we also talked about the damage these types of attacks can do.
Frequently Asked Questions (FAQs): Can a ddos attack be prevented?
Can a firewall stop a DDoS attack?
No firewalls can not stop a DDOS attack.Although firewalls are designed to, and still do, protect networks from a variety of security issues, there are a number of security vulnerabilities when it comes to DDoS and malicious server targeted attacks.In such cases a firewall alone cannot prevent a sophisticated distributed denial of service.
Does a VPN protect you from DDoS?
No, a VPN cannot stop a DDoS attack. A VPN can’t outright stop a DDoS attack. In fact, a single device can not stop a DDoS attack. However, a VPN can prevent an attack from doing any real harm to your business. By having remote VPN servers, you protect your actual servers from being attacked.
What protects from DDoS?
There are many ways to protect from DDoS. You can prevent a DDoS attack by making a few simple hardware configuration changes. For instance, you can configure your firewall or router to drop incoming ICMP packets or block DNS responses from outside your network (by blocking UDP port 53).
