Ddos protection hosting
What is DDos Attack?
A Denial of Service attack (DoS) or Distributed Denial of Service attack (DDoS) aims at rendering a computer resource either unavailable or with sufficiently crippled user accessibility. There are different techniques and means to launch such attacks. Motives could also be very varied, as well as the targets. DDoS attacks usually represent the organized attempts to make a web site or service not function or cause sufficient downtime for a limited time or permanently.
Typical targets of DoS attacks include all kinds of (prominent or not so prominent) sites or services such as financial and banking institutions, online e-commerce establishments, news & media sites, online gaming communities, the public sector, and lately, even entire countries.
Type of Ddos
There are four primary types of DDoS attacks that provide the foundation for numerous variations and combinations. Below is a brief description of what they are and how they affect site/server accessibility.SYN flood - numerous TCP connection requests (SYN packets, the first packet of the three-way handshake) are sent to a machine at such a rate that it cannot cope to process all of them. Often, these packets are sent with randomly-generated spoofed source IP addresses. The server responds to SYN request by sending a SYN-ACK trying to establish a valid connection, then waits for confirmation (ACK) for some time, yet such confirmation never arrives. Thus, the connection table of the server fills up and as it does, all new connections are dropped and legitimate users are effectively cut off from accessing the server.
Connection flood is an attack that creates a vast number of empty connections to the targeted server. Only packets establishing the three-way handshake (SYN, SYN-ACK, ACK) are sent with no data transfer, the server starts waiting, within keepalive TCP parameters if such are set at all, for data that never comes through. As the name suggests, the aim is to create a large number of real connections, coming from real IP's, eating into the backlog connection capacity of targeted web servers.
UDP flood is mostly aimed at bandwidth depletion. A large number of big (up to 35Kb) packets are being sent, often with spoofed source IP addresses to a targeted host through the stateless computer networking protocol UDP. In order to intensify bandwidth abuse, sometimes packets are sent to random ports on the host, thus increasing return ICMP rates, in which case the victim server usually replies with an ICMP Destination Unreachable packet after checking for application listening at the respective port and finding none. Connection bandwidth is depleted, rendering the server unreachable by real clients.
HTTP flood aims to bring down a machine through en masse addressing of a single or multiple URLs within a domain, thus causing a webserver overload and as a result - hardware resource depletion. HTTP Flood attacks sometimes lead to physical destruction of server hardware, due to its inability to cope with the overload on CPU and RAM. Rather than going after static content, attackers prefer to target dynamic content in order to amplify hardware load. As the server gets busy with the attack requests, it cuts off or considerably slows down "good" traffic generated by legitimate users.

Remote Desktop Protocol
Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft, which provides a user with a graphical interface to connect to another computer over a network connection. The user employs RDP client software for this purpose, while the other computer must run RDP server software.
Clients exist for most versions of Microsoft Windows (including Windows Mobile), Linux, Unix, Mac OS X, iOS, Android, and other modern operating systems. RDP servers are built into Windows operating systems; an RDP server for Linux also exists. By default, the server listens on TCP port 3389.[1]
Microsoft currently refers to their official RDP server software as Remote Desktop Services, formerly "Terminal Services". Their official client software is currently referred to as Remote Desktop Connection, formerly "Terminal Services Client".
The protocol is an extension of the ITU-T T.128 application sharing protocol.
Security issues
The RDP protocol in its default configuration is vulnerable to a man-in-the-middle attack. Administrators can enable transport layer encryption to mitigate this risk.
RDP sessions are also susceptible to in-memory credential harvesting, which can be used to launch pass the hash attacks.
In March 2012, Microsoft released an update for a critical security vulnerability in the RDP protocol. The vulnerability allowed a Windows computer to be compromised by unauthenticated clients and computer worms.
RDP client version 6.1 can be used to reveal the names and pictures of all users on the RDP Server (no matter which Windows version) in order to pick one, if no username is specified for the RDP connection.

Linux-VServer
Linux-VServer is a virtual private server implementation that was created by adding operating system-level virtualization capabilities to the Linux kernel. It is developed and distributed as open-source software.
The project was started by Jacques Gélinas. It is now maintained by Herbert Pötzl of Austria and is not related to the Linux Virtual Server project, which implements network load balancing.
Linux-VServer is a jail mechanism in that it can be used to securely partition resources on a computer system (such as the file system, CPU time, network addresses and memory) in such a way that processes cannot mount a denial-of-service attack on anything outside their partition.
Each partition is called a security context, and the virtualized system within it is the virtual private server. A chroot-like utility for descending into security contexts is provided. Booting a virtual private server is then simply a matter of kickstarting init in a new security context; likewise, shutting it down simply entails killing all processes with that security context. The contexts themselves are robust enough to boot many Linux distributions unmodified, including Debian and Fedora.
Virtual private servers are commonly used in web hosting services, where they are useful for segregating customer accounts, pooling resources and containing any potential security breaches. To save space on such installations, each virtual server's file system can be created as a tree of copy-on-write hard links to a "template" file system. The hard link is marked with a special filesystem attribute and when modified, is securely and transparently replaced with a real copy of the file.
Linux-VServer provides two branches, stable (2.2.x), and devel (2.3.x) for 2.6-series kernels and a single stable branch for 2.4-series. A separate stable branch integrating the grsecurity patch set is also available.
Virtual servers share the same system call interface and do not have any emulation overhead.
Virtual servers do not have to be backed by opaque disk images, but can share a common file system and common sets of files (through copy-on-write hard links). This makes it easier to back up a system and to pool disk space amongst virtual servers.
Processes within the virtual server run as regular processes on the host system. This is somewhat more memory-efficient and I/O-efficient than whole-system emulation, which cannot return "unused" memory or share a disk cache with the host and other virtual servers.
Processes within the virtual server are queued on the same scheduler as on the host, allowing guests processes to run concurrently on SMP systems. This is not trivial to implement with whole-system emulation.
Networking is based on isolation rather than virtualization, so there is no additional overhead for packets.
Smaller plane for security bugs. Only one kernel with small additional code-base compared to 2+ kernels and large interfaces between them.
Rich Linux scheduling features such as real-time priorities.
Requires that the host kernel be patched.
All virtual servers share the same kernel so all must be Linux. (Because of backwards compatibility in user-space API, this does not impair use of old Linux programs or distributions.[citation needed])
No clustering or process migration capability is included, so the host kernel and host computer is still a single point of failure for all virtual servers.
Networking is based on isolation, not virtualization. This prevents each virtual server from creating its own internal routing or firewalling setup.
Some system calls (mostly hardware-related: e.g. real-time clock) and parts of the /proc and /sys filesystems are left unvirtualized.
Does not allow disk I/O bandwidth to be allocated on a per-virtual server basis.

what is Virtual private server (vps) ?
A virtual private server (VPS) is a virtual machine sold as a service by an Internet hosting service.[1]
A VPS runs its own copy of an operating system, and customers have superuser-level access to that operating system instance, so can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software defined are able to be much more easily created and configured. They are priced much lower than an equivalent physical server, but as they share the underlying physical hardware with other VPSs, the performance may be less, and may depend on the workload of other instances on the same hardware node.
The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualisation used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in 2001. The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines. These guest operating systems are allocated a share of resources of the physical server, typically in a manner in which the guest is not aware of any other physical resources save for those allocated to it by the hypervisor. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS, however due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.
Although VMware and Hyper-V dominate in-house corporate virtualization, they are less common for VPS providers, mainly due to cost and limitations - who typically use products such as OpenVZ, Virtuozzo, Xen or KVM.
Many companies offer virtual private server hosting or virtual dedicated server hosting as an extension for web hosting services. There are several challenges to consider when licensing proprietary software in multi-tenant virtual environments.
With unmanaged hosting, the customer is left to administrate their own server instance.
Unmetered hosting is generally offered with no limit on the amount of data-transferred on a fixed bandwidth line. Usually, unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s (with some as high as 10Gbit/s). This means that the customer is theoretically able to use 3.33~ TB on 10 Mbit/s, 33~ TB on 100 Mbit/s and 333~ TB on a 1000 Mbit/s line per month (although in practice the values will be significantly less). In a virtual private server, this will be shared bandwidth and (should) mean there is a fair usage policy involved. Unlimited hosting is also commonly marketed but generally limited by acceptable usage policies and terms of service. Offers of unlimited disk space and bandwidth are generally false due to carrier capacities and technological boundaries.
A VPS which is dynamic (that is, it can be changed at runtime) is often referred to as a cloud server. Key attributes for this are:
Additional hardware resources can be added at runtime (CPU, RAM)
Server can be moved to other hardware while the server is running (automatically according to load in some cases)

A virtual private server or VPS is a type of internet hosting service that makes use of a virtual machine. The so-called virtual machine is the one that caters the needs of each and every user. Well in terms of its overall service, it is quite similar to a shared web hosting service. However, the main difference is that the given server functions that you will receive is similar to a dedicated server. It is mainly enhanced to give all your web hosting needs. It offers useful tools that let you create and configure your own site. It also does not jeopardize the security of your website since it offers the similar privacy that you could experience with a separate server. It can also be easily configured to run different software systems.
As mentioned before, a VPS hosting offers utmost independence for your site. Well, the basis for such statement is that it practically offers you unmanaged and unmetered hosting options. For unmanaged hosting, you are given the opportunity to take care of your own web site. From its maintenance, configurations to all other little details, you are responsible for everything.

A VPS runs its own copy of an operating system, and customers have superuser-level access to that operating system instance, so can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software defined are able to be much more easily created and configured. They are priced much lower than an equivalent physical server, but as they share the underlying physical hardware with other VPSs, the performance may be less, and may depend on the workload of other instances on the same hardware node.
Virtualization
The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualisation used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in 2001. The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines. These guest operating systems are allocated a share of resources of the physical server, typically in a manner in which the guest is not aware of any other physical resources save for those allocated to it by the hypervisor. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS, however due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.
Although VMware and Hyper-V dominate in-house corporate virtualization, they are less common for VPS providers, mainly due to cost and limitations - who typically use products such as OpenVZ, Virtuozzo, Xen or KVM.
Hosting
Many companies offer virtual private server hosting or virtual dedicated server hosting as an extension for web hosting services. There are several challenges to consider when licensing proprietary software in multi-tenant virtual environments.
With unmanaged hosting, the customer is left to administrate their own server instance.
Unmetered hosting is generally offered with no limit on the amount of data-transferred on a fixed bandwidth line. Usually, unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s (with some as high as 10Gbit/s). This means that the customer is theoretically able to use 3.33~ TB on 10 Mbit/s, 33~ TB on 100 Mbit/s and 333~ TB on a 1000 Mbit/s line per month (although in practice the values will be significantly less). In a virtual private server, this will be shared bandwidth and (should) mean there is a fair usage policy involved. Unlimited hosting is also commonly marketed but generally limited by acceptable usage policies and terms of service. Offers of unlimited disk space and bandwidth are generally false due to carrier capacities and technological boundaries.
Cloud servers
Main article: Cloud computingA VPS which is dynamic (that is, it can be changed at runtime) is often referred to as a cloud server. Key attributes for this are:
Additional hardware resources can be added at runtime (CPU, RAM)
Server can be moved to other hardware while the server is running (automatically according to load in some cases)

Wat is website hosting?
Website hosting is het beschikbaar stellen van een stuk schijfruimte
op een server, een computer die continu met het internet verbonden is,
waarop bijvoorbeeld de pagina's van een website op geplaatst kunnen
worden.
Zo'n afgebakend stuk schijfruimte, met alle bijbehorende diensten en beheermogelijkheden, noemen we een hosting account.

Web hosting is the service that makes your website
available to be viewed by others on the Internet. A web host provides
space on its server, so that other computers around the world can access
your website by means of a network or modem. There are literally
thousands of web hosting services available today, ranging from free
services with limited options to expensive, specialized business web
hosting services. Which option you choose depends primarily on how you
plan to use your website and how much you want to spend.
Types of Web Hosting Services
Internet Service Providers (ISPs)
Many people put up their first websites through their ISPs,
because it's generally easy and inexpensive. Most ISP service packages
include a small amount of free web space, along with tools to create and
upload websites quickly and easily. ISP websites are perfect for people
who want to put up small sites with low amounts of traffic. However,
there are usually rate restrictions, and most ISPs don't offer a lot of
features, so they might not be the best choice for a thriving business
website.
Free Web Hosting
Free web hosting is another good option for smaller, personal
websites. There are many free hosting providers that offer all types of
features; some include CGI access and more. The drawback to most free
hosting services is that they are funded by advertising that appears on
your site, so free web hosting so generally best for personal, rather
than business, websites.
Paid Hosting
With paid hosting, you pay a fee for space and services on a web
hosting provider's server. Monthly fees can range from a few dollars to
several hundred dollars. Obviously, the more you pay, the more features
you should have at your disposal. Services can include CGI access,
database support, ASP, e-commerce, SSL, additional space on the server,
extra bandwidth, and more.
Domain Hosting
A good option for small businesses is to pay for domain hosting.
Domain hosting allows you to host your site anywhere you like: on an
ISP, a free hosting service, or even your own server. You buy a domain
name and have the provider forward all requests for that domain to the
actual web location. This is often less expensive than buying both the
domain and the hosting service, and it allows businesses to brand their
URLs.
Collocation
Collocation is an option for businesses that want to run their
own web servers and machines, but don't want to have to maintain them
directly. With collocation, the website owner places its own server on
the premises of its ISP or other host, where it is stored, maintained,
and provided with an uninterrupted power supply. Collocation provides
security and protection for your server while still giving you control
of your own equipment.
Direct Internet Access
Hosting your site yourself offers you the most control over your
web server. Companies with large data centers or that require high
security in every aspect of their web and Internet access should look
into this type of hosting.
