Private cloud security: Which programs and tools are more effective

Although the public always mistakenly thinks that private cloud isSecurityIn fact, Private clouds are not absoluteSecurityBecause it is private. To ensure the security of the private cloud, you must develop a comprehensive plan and conduct regular checks to ensure the security of the private cloud and avoid losses.

To ensure the security of the private cloud, you must first check the security of the network where the private cloud is located. Depending on the nature of a specific private cloud, there are multiple inspection forms. However, for most networks, protocols and checks are the most common.

The first step in maintaining private cloud security is planning. In the planning phase, protocols and programs are executed to access data in the private cloud. If you only access the cloud, it is clear that the company must ensure that these services are not accessible from the outside. However, if employees are in the company's external network and access private cloud resources, it is important to determine how to obtain data and put the authentication mechanism in place. In addition, if there are limits, determine which resources need to be configured with access restrictions. If several users are simultaneously accessing resources, creating multiple virtual machines (VMS) and running multiple applications, the private cloud may be overloaded and the security of the private cloud may be threatened. Therefore, plan in advance to reduce this risk and execute the protocol.

When building a private or public cloud, the company must ensure that it is equipped with dedicated security personnel to reduce risks. Security personnel are responsible for protecting the operating environment and are ready to respond to catastrophic events at any time.

Test the security of private cloud

Periodic Wireshark or TShark capturing on physical machines covers virtual infrastructure. Once administrators know which types of traffic can be used to access the network and which types of traffic cannot be used to access the network, they can easily write scripts. Developing a baseline about what is normal network behavior is also a good way. For example, if the network administrator knows that his private cloud does not have DHCPServerHowever, they see "DHCP" Information in Wireshark capture and further investigation is crucial.

When Wireshark is used in a private cloud environment, ensure that the capture is completed from a host. In this way, network traffic can be fully captured, rather than simply captured from the virtual machine.

In additionSystemLog check because these logs belong to the private cloud environment. There are many hardware devices and software applications that perform Automatic Log Analysis to complete alarm triggering and alarm messages. For example, if a person attempts to log on to the private cloud at two o'clock P.M. on Saturday, this may be automatedSystemIt is deemed invalid. However, these systems are also created by humans, and they will never completely replace an experienced person with the ability to detect exceptions. Therefore, it is necessary for an experienced professional to perform regular checks.

 

Is it worthwhile to transfer to the public cloud?

 

Many organizations move to the public cloud. Because of the cost of uninstalling cloud infrastructure and the responsibility for maintaining cloud infrastructure, it is worth the Organization's time and money. But is it the best way to move to the public cloud from the security perspective? The answer is both positive and negative.

Many companies do not consider DOS attacks.AttackAnd other formsAttackBecause the company's infrastructure exists in one of the massive data centers of Amazon Web Services. If the Organization's infrastructure is attacked by attackers, the provider is responsible for this. However, over the weekend, companies should set up a call system, arrange network administrators, and invest a lot of time and resources to avoid private cloud attacks.

Advantages of public cloud

On the other hand, companies that decide to move to the public cloud-if any-rarely know where the data is stored and how to process it. When a company uses a public cloud, it does not have the root access permission for the physical machine where the public cloud is located. Therefore, a person with a bad attempt can access the given box and destroy the data of a company if he has root access permissions. Currently, public and private clouds still have advantages and disadvantages.
