Cloud Server security is an extremely important issue, especially since most businesses today use Cloud servers to store information and data.

Cloud Server security keeps data safe from Hacker attacks

Website data, customer data, employee records, transaction history are all extremely important assets of every business. Once these data are stolen, businesses can suffer serious consequences in terms of time, money, brand reputation. That’s why Cloud Server server security is very important. More specifically, please follow the article below.

Why is Cloud Server security important?
Security for Cloud Server is a necessary and extremely important issue because of the abuse and continuous operation of network hackers. Today, any loophole in security is used by hackers to bring malicious software into your network. More importantly, these software are installed immediately and completely automatically. In that situation, businesses need to choose the best Cloud Server security system and use firewalls to prevent them. Once infiltrated by malware, important data and customer information of the Enterprise can be stolen by Hackers. In addition, they destroy important files and applications.

Cloud Server security optimization need to do?
There are many Cloud Server security methods that you can apply. Whether you are a Cloud Server or Dedicated Server manager or are in the process of learning or have little experience, you can choose the right solution for you.

SSH Security
Use a secure password
Apache Security
Tight data security
System reinforcement
Turn on the firewall
Turn off unused Services and Daemons
Security alert 24/7/365

SSH Security
SSH security is a way to protect Cloud Server servers. It is recommended to switch SSH access to a different port for increased security. To customize the port on which SSH runs, edit the file /etc/ssh/sshd_config. Better yet, you should use a port with a sequence number less than 1024 and not yet used for any other service. Because the ports are used only Root Users can bind to them.

Ports of 1024 or higher are ports that can be used by anyone. Note that SSHv2 should always be used, as SSHv1 is not secure. In addition, you need to change the #Protocol 2.1 line in the /etc/ssh/sshd_config file to Protocol 2.

Use a secure password
Using a secure password is essential to ensure the safety and security of Cloud Server. You can edit the /etc/login.defs file to configure many password options on the system. A secure password needs to be at least 8 characters including numbers and letters. In addition, you must not use passwords that contain dictionary words or popular dates.

Apache Security
The fastest and easiest way to access a Web Cloud Server is through applications on this Web Server. Therefore, installing Apache security is essential. Accordingly, using the ModSecurity™ tool will help you prevent the use of Apache for malicious purposes. You can use the following interfaces to manage ModSecurity in cPanel & WHM version 11.46 and later:

WHM’s ModSecurity™ Configuration interface (Home >> Security Center >> ModSecurity™ Configuration)
WHM’s ModSecurity™ Tools interface (Home >> Security Center >> ModSecurity™ Tools).
Tight data security
Tight data security is a top priority. Accordingly, if a customer accesses the system, it will have to go through a strict process and only some senior engineers under the customer’s permission can access that customer’s Server. This ensures data is always safe.

Your data must be kept safe

System reinforcement
System Fortification is another Cloud Server security you can use. Accordingly, you should mount a separate /tmp partition with the nosuid option. This will force a process to run with the privileges of its executor. After installing cPanel and WHM you also need to mount the /tmp directory with noexec. In addition, it is necessary to mount the /tmp partition to a temporary file to run the script /scripts/secure tmp for backup purposes.

If you don’t want to run Script /scripts/secure tmp, you can create File /var/cpanel/version/secure tmp disabled. To do this, run the following command: touch /var/cpanel/version/securetmp_disabled. This file prevents the Script from running on your Cloud Server. But you should not disable Script /scripts/securetmp.

Turn on the firewall
Installing a firewall to limit access to the Server or remove unused software on the system is a way to increase security. You can turn on the firewall to prevent unwanted access before removing unnecessary Services or Daemons.

Turn off unused Services and Daemons
Often Hackers will take advantage of Services or Daemons that are able to connect to the Server. To limit this risk, turn off unused Services or Daemons through WHM’s Service Manager interface.

Security alert 24/7/365
Security Alert 24/7/365 is a pretty good way to secure Cloud Server. By immediately notifying when the server is attacked, providing information about the attack status, the attack flow will help you stay proactive and have a quick and timely response. It is essential to arrange an experienced technical team that is always ready to respond and support 24/7.

Server security solution when renting Cloud Server at ODS
In addition to the above Cloud Server security methods, when renting a Cloud Server at ODS, you will be able to use Storage Space Direct storage technology to increase security.

What is Storage Space Direct storage technology?
Storage Space Direct in Windows server 2016 is an upgrade from the Storage Space feature in Windows server 2012 R2. It provides Highly Available – Scalable Storage through the use of Local Disks on the Server.

This makes the deployment and operation of Windows Storage more efficient and cost-effective. In addition, Storage Space Direct technology also allows the use of more types of storage devices in the Storage infrastructure such as SATA SSD and NVMe Disk.

Storage Space Direct uses Mirror algorithm to protect Cloud Server

Outstanding advantages of Storage Space Direct
Storage Space Direct technology possesses many outstanding advantages such as:

Simple: the time to Deploy this technology is less than 15 minutes.
High performance: Storage Space Direct can achieve 150,000 Mixed 4K Random IOPS per Server. Best of all, it has low latency thanks to its Hypervisor-Embedded, Built-In Read/Write Cache architecture. In addition, S2D supports NVMe devices to increase Storage performance.
Fault Tolerance: Built-in recovery feature that handles disk or Server failure without affecting data.
Efficient Resource Management: Erasure Coding provides up to 2.4x more efficient storage space with unique innovations such as Local Reconstruction Codes and real-time tiering that increase the ability to exploit the advantages of hard drives, mixed hot/cold workloads, which reduces CPU consumption to serve other resources like VMs on Hyper-V.
Manageability: Use Storage QoS Control to manage IOPS for each VM and Scale-Out File Server roles. Healthy Service provides inbuilt features monitoring and alerting. New APIs make it easy to collect Performance and Capacity metrics across the board.
Scalability: This technology requires a minimum of 2 Nodes and can be scaled up to 16 Nodes and 400 hard drives. In addition, storage capacity can be up to Petabytes per Cluster. Cluster expansion is very simple, you just need to add a hard drive or a Server, Storage Spaces Direct will automatically integrate new hard drives and load balance them.

Server data protection mechanism
Storage Space Direct (S2D) protects data by providing algorithms that ensure a level of security and resiliency in the event of failure:

Mirror Algorithm: works by dividing the data and multiplying it according to the specified number of Replicas. This algorithm keeps data safe and resilient when a certain Node in the Cluster crashes. It should be noted that there must be at least 2 Nodes in the Cluster to Enable Mirror Resiliency. Mirror algorithm has 2 options including:

Two-way mirror: there are 2 copies of data mirror. This option is fault tolerant with a failed disk or server.
Three-way mirror: has 3 copies of data, fault tolerance with 2 servers dying unexpectedly.
The data is broken down and transferred to the Server, along with the Parity part (the amount you want). For Parity, at least 4 Nodes in the Cluster are required to Enable Parity Resiliency. Parity also has 2 options:

Single parity: Similar to RAID5, the system will have 1 copy of Parity and can be fault-tolerant with a failed disk or server.
Dual parity: Similar to RAID6, there are 2 versions of Parity, fault tolerance with 2 disks or Server failures, good data recovery ability.
