Automation technology can aid in the prevention of cyber-attacks however, it is also dependent on human expertise and monitoring to safeguard your website to its maximum extent. Traditional web design structures don’t suffice. Multi-layered cloud security created and monitored by highly skilled and dedicated engineers is the best way to protect your business. Knowing the way DDoS attacks operate and becoming familiar with the behaviour on your networks are essential actions to prevent interruptions, intrusions, or downtime due to cyber attacks. Here are some suggestions to prevent DDoS attack:

1. Use a sound system of monitoring networks
The first step to reducing DDoS threats is to recognize whether you’re about to be hit by one. This requires installing technology that permits you to check your network in real-time. Find out how much bandwidth that your site consumes in order you can monitor the instances of irregularities.
DDoS attacks can be detected visually and, if you’re very familiar with your network’s behavior and patterns, you’ll be better capable of detecting the attacks in real-time.
2. Make sure you practice basic hygiene for security
There are easy steps that every company can do to provide a minimum security level to defend against DDoS threats. These include the best practices like using complicated passwords, having the reset of passwords every couple of months, and avoiding making notes of passwords. This may sound like a trivial thing, however it’s alarming how many businesses are at risk due to not taking care of basic security practices.
3. Create basic traffic thresholds
You are able to reduce DDoS attacks by using a few other measures of security. This includes setting traffic thresholds and limits, such as rate limitation on your router as well as filters for packets coming that come from suspect sources. Set the lower SYN, ICMP and UDP flood drop thresholds, IP forwardlisting, signature identification and geo-blocking are additional methods you can use as a starting point of defense. These are simple measures that will allow you to save time, but DDoS attacks are always changing in sophistication, and you’ll have to have additional strategies in place to stop these attacks.
4. Make sure your security system is up-to-date
Your network is as solid as the weakest link in your network. This is the reason it is crucial to keep an eye on the legacy and obsolete systems within your network as they can often be gateways to attacks after they have been damaged.
Maintain your data center as well as system up to date and patch your internet application firewalls as well as other security software for networks. In addition cooperating together with the ISP as well as hosting company, your security, and data center vendors to implement additional advanced security features is also an excellent idea.

5. Prepare yourself with an DDoS response strategy
If an attack like a DDoS attack is detected in the near future, it’s already too late to think about how to respond. You must have a plan of attack prior to the attack so that effects are reduced. The plan for response should contain
- Checklist of tools – A list of all tools that will be utilized with the most advanced detection and assessment of threats, and filtering and both hardware and software.
- Response team – a group of individuals with clear tasks and responsibilities that they must be able to carry out when an attack is discovered.
- Escalation protocols are clearly defined guidelines on who to inform, escalate, and include in the event of an attack
- A communication plan is a plan for communicating with external and internal stakeholders, such as your ISP as well as vendors and customers. It also outlines how to convey information in real-time.
6. Make sure you have enough server capacity
Because the volumetric DDoS attacks operate by consuming the bandwidth of networks One way to stop them is to increase bandwidth. Therefore, by ensuring that your server’s capacity can handle the heavy traffic surges by increasing bandwidth, you’ll be prepared for sudden and unexpected increases in traffic that are caused through DDoS attacks. Be aware that this won’t completely stop an DDoS attack entirely, but it gives you some extra time to plan other defenses prior to the resources you have are exhausted.
7. Explore cloud-based DDoS protection options
It is also advisable to investigate the cloud for DDoS security strategies as part DDoS reduction strategy. Cloud-based solutions provide more capacity and bandwidth compared to private networks. Cloud data centers can absorb harmful traffic and redirect the traffic to different areas and block them from reaching their intended users.
8. Use a Content Delivery Network (CDN)
A modern and effective way to combat DDoS attacks is to utilize the the content delivery network (CDN). Because DDoS attacks are based on overloading servers that host websites CDNs are able to help by distributing the load across multiple servers located geographically and are closer to the users. So, in the event that one server fails it will be replaced by another operating. CDNs may also offer certificate management as well as automated renewal and generation of certificates.
9. Get professional DDoS mitigation support
Do not hesitate to speak to an experienced. DNS providers and companies such as CDNetworks can assist you in protecting your website’s assets by redirecting visitors when needed, analyzing the performance of your site and dispersing traffic among several servers should an attack happen.
The Cost of DDoS Attacks
DDoS attacks, as well as the motives behind them have changed since the attacks of 1990s. Nowadays, they are more ferocious and easier to launch and usually based on political motives. Everyday there are orchestrated cyber-attacks that take place not just on big target companies, but on smaller and medium-sized companies too. There aren’t many companies that are prepared enough to stop them however. The financial burden for businesses is growing exponentially, and estimates suggest that it will be around $500,000 or so. However, according to experts that most fifty million hacks every year are not detected. The price of a cyberattack for companies isn’t just an interruption in revenues, productivity, and chances for business, but it can also cause an injury to the image of the business. The cost of operations can skyrocket in many situations, as companies try to discover and repair their security weaknesses.
Steps to Take if You’re Attacked
While early detection is essential to avoiding devastating consequences however, there are steps to follow if you’re victimized by an DDoS attack. First, make sure that you have an online DDoS protection system installed that can deal with attacks. Other steps include:
- New IP addresses to be set up for your systems
- Ensure DNS Records are in place to provide the highest level of security
- Blocking countries that are recognized by the DDoS attack as DDoS attack hubs
- A dedicated server for email
- Connecting to your servers and recording the connections
