In late 2016, a new era of massive DDoS attacks has arrived. Last fall, we confirmed the launch of Mirai, the prototype for numerous attacks affecting sites like Twitter, Netflix, Reddit, and CNN. A month later, Mirai-type DDoS attacks continued against various email providers and other targets, including Comcast.

While cyberattacks can be detrimental to a business, looking back on the lessons learned from past disasters can help prevent future attacks and repair existing vulnerabilities. These five best practices help strengthen overall cybersecurity and protect users from potential DDoS attacks and other malicious attacks.

DDoS Attack Basics

A distributed denial of service attack (DDoS) is a type of cyber attack that repeatedly attacks a server through a large group of connected devices. Sometimes many aspiring participants can unintentionally activate managed ddos services, such as those looking to buy coveted items, like concert tickets and Black Friday sales. However, DDoS attacks often consist of a legitimate set of malicious participants whose device was infected by malware. This is known as a botnet. The first is increasing pain that can be simply designed, while the second is a malicious attempt at state-sponsored or industrial sabotage that can be harmful or even deadly to business. It is.

In a Botnet-based DDoS attack, the network of devices infected with malware (under the attacker's control) simultaneously sends requests to the target server, overwhelming its resources. Computers, smartphones, media players, appliances, and any web-enabled devices can become infected and added to the botnet. There are three types of DDoS attacks (volume-based, protocol-based, and application-layer attacks), but they all work with (almost) the same resource drain tactics.

5-step DDoS protection plan

While malicious actors are always looking for new targets to compromise, there are a few steps they can take to limit their exposure to these attacks. Once the attack begins, it is too late to implement most of these tactics. However, these steps reduce the damage caused by the attack.

  1. Monitor Traffic

You must be familiar with common traffic patterns to understand if your site is under attack. Web traffic spikes can be part of normal business. Advertising, promotions and events can lead to an increase in visitors to your site. Knowing when these events occur can help you understand their impact on traffic. This helps to identify that unusual traffic is being sent to the server. DDoS attackers generally initiate a small intrusion before a major attack.

  1. Overprovisioning Of Network Resources

Providing sufficient network capacity for a site is another important component of preparing a site for potential DDoS attacks. Excessive bandwidth allocation can provide a small but useful buffer for a site in the event of an attack. Earn valuable by securing excess network capacity to handle large spikes in traffic. We recommend that your network handle 2 to 6 times normal traffic.

However, even with adequate network provisioning, even if the upstream providers don't have the capacity, DDoS attacks can have a significant impact on a product or service. A good example of this can be seen in actual highway traffic. Even the most intricate traffic management systems and ramps cannot avoid traffic congestion if the main roads are poorly built or have too much capacity. By ensuring that upstream providers also have the resources to handle large-scale DDoS attacks, you can ensure that precautions are not wasted in the event of a large-scale attack.

  1. Stay Alert

Some network equipment will spend years with minimal security incidents. This type of success can often lead to self-satisfaction resulting in the failure of corporate security measures. This makes them very vulnerable to attack. It is easy for a team to be distracted by a minor vulnerability, but it is crucial to look for weaknesses in the strongest network components. Failure analysis in larger areas of success may seem contradictory, but it is essential to strengthen your network and prepare for possible attacks.

4.Using a dedicated server or hybrid cloud server

Hosting a product or service on a dedicated server or hybrid cloud server is an important part of protecting your product from DDoS attacks. Verifying that the site is the only tenant on the server allows full access to all security settings and resources. Shared hosting, VPS, and semi-dedicated hosting clients have limited security options set by the host to protect other tenants on the server. These limited security options, along with the inherent risk of sharing the server with another tenant, make your site more vulnerable to malicious traffic.

  1. Install Available Updates

Keeping applications up-to-date is an important component of cybersecurity that is often overlooked. DDoS attacks often target recently discovered security holes. Installing immediately after installing an update on an open source platform like WordPress will provide you with the latest secure version available. Updates are often ignored, but selecting the latest version allows you to patch and remove previously released security holes. If you choose to install updates automatically, you always have the most secure application available.
