VDS/VPS servers with DDoS protection

VPS servers with DDoS protection

DDoS is a kind of network attack, which basically boils down to creating such a load on the server that it will not be able to cope adequately with user requests. As a result, the server "goes down", the real visitors can not access it, and the site owner suffers reputational and financial losses.

As a rule, the initiators of attacks are either competitors or simply ill-wishers, for whom a particular site prevents a quiet life. That is why VPS with DDoS protection are popular among representatives of large and medium-sized businesses. The bigger the business is, the more potential enemies are and the higher is the need for this kind of protection.

Protection options and their differences

There are three types of DDoS attacks:

1. Protocol attacks (at L3, L4 levels). The purpose of such attacks is to overload the table space on the screen with a firewall in the network. It works in the following way: on several layers a large number of requests are launched, which the target node has no time to process, which causes a failure. A FIFO rule with sequential processing of requests can not always protect, because as a result of network flooding the server simply does not have enough resources to complete the original request. There are five variants of such flooding: HTTP, SYN, UDP, MAC and ICMP. They can often be combined for better performance.
2. Applied. Attacks at infrastructure level, aimed at overloading the hardware part of the server, thus causing a state of failure on the CPU. It is achieved in different ways. The first one is filling server with log files due to script; this variant will work if there is no limit set on VPS. The second option is to send oversized packets, which the server can not cope with. The third scenario involves a quota system, but the hacker will need access to the CGI.
3. Attacks on applications (L7 level). For these DDoS attacks, the hacker would need to find vulnerabilities at the source code level, and then come up with mechanisms to exploit them. All of the existing exploit programs are from here.

In general, there are many attack options, so most companies use different methods to protect data and servers in general.

Keep in mind the fundamental principle that "there is always a counteraction to every action", so there are also quite a few mechanisms for protecting against DDoS attacks. We can divide them into three types:

1. Local. These include a variety of specialized software, as well as network devices that help prevent DDoS.
2. Cloud-based. This is a software variant of protection, but such software runs on another server, in the cloud. The advantage of cloud technologies is that a hacker cannot somehow disable or bypass them, except by hacking the developer's servers - and this is virtually impossible if the service provider is a serious company with a proven track record. Cloud DDoS protection today is one of the most common options, especially since the use of such solutions does not affect the client's server itself.
3. Hybrid. Complex solution, a combination of two previous types of protection. They demonstrate even higher efficiency, but also are more expensive, that's why they are mainly used by large corporations.

For whom is this service intended

According to 2021 statistics, about 40% of all DDoS attacks targeted the entertainment industry, slightly more than 29% targeted the telecommunications industry, and 12% targeted online retailers. Websites in construction (6%), finance (4.5%) and education (3.6%) suffered the least DDoS attacks. This data allows every businessman to assess all possible risks and decide for himself whether he needs to rent a virtual dedicated server with protection against DDoS attacks.

As for web applications, it is almost always necessary to provide this kind of protection, because according to the same year 2021, they were twice as often the victims of hackers than sites and portals. The reason is simple - web applications collect much more data about users, and once hacked, they can easily be used to their advantage.

This service is for anyone interested in ensuring that their project is protected from the encroachment of ill-wishers and competitors. You can rely on the interest, but no one can guarantee that your site will not become a target for attackers, even if statistically it is in the lowest-risk zone.

Advantages of HostZealot over other services

HostZealot offers the ability to lease secure VPS - we use hybrid DDoS protection mechanisms on hardware and software levels, which will monitor all incoming traffic in order to counteract artificial server overload. Configured packet dropping filters allow to cut off any unwanted traffic, which may negatively affect VPS operation.

Protection of servers on a network and transport levels (L3, L4) is provided by the fact that all incoming traffic goes through several filtering nodes, where it is carefully analyzed and cleared of spam, floods and other unwanted packets. We can handle loads of up to 400 Gbps.
