Crucial Aspects of Cloud Security
Cloud computing has revolutionized the way we store and handle data, resources and tools. Cloud computing offers many advantages, and there has been an increase in its use over the past decade. The adoption of cloud computing has created the need for guarding against an internal threat, preventing data loss and protecting businesses from threats.
What is cloud computing?
Cloud computing is the use of online servers to store and provide data services, resources and tools.
You can access data, run memory intensive programs from the cloud. The most common application of cloud computing is the storing of data.
Why is cloud computing important?
Cost reduction: Cloud computing eliminates the need for physical space and hardware. Massive amounts of data can be stored with a cloud computing provider. Clients can get access to a resource without needing to acquire them. They can use these resources on a pay-as-you-go basis.
Security: Cloud providers implement top-notch security standards and protocols to keep your data completely safe. Companies can channel the time spent on securing and update into more productive ventures. This can also cost and improve the overall productivity of an organization.
Easy access to data: Cloud computing gives authorized clients easy access to data from any location. To safeguard your data, a client must use a secure internet connection for accessing these files. Using public Wi-Fi can leak sensitive data to hackers.
Cloud computing is also useful for data analytics. People can have access to massive data sets stored in the cloud. Businesses and organizations can take advantage of this and can have access to data from numerous sources.
This can also help experts in the field of software development. Cloud computing gives software developers room to store and access more data.
Flexibility: Cloud providers offer clients flexible service options and access to pre-built tools. Because clients can easily change their demand for tools and resources, cloud computing is a superb option for fluctuating workload.
Disaster recovery: Having a disaster recovery plan is crucial for any business or establishment. Earthquakes, fires or any other natural disaster can strike without warning.
These ‘acts of God’ can wipe your entire database. This can damage your reputation and decimate the trust built with your clients.
The only remedy to this is to securely store your data in a safe and isolated place.
Cloud computing security
Cloud computing security involves the protection of data, applications and resources used in cloud computing. It is an essential part of cyber-security. It consists of several policies, technologies and protocols that ensure critical information and resources are secure and accessible to clients.
Data security: This is one of the most important aspects of cloud security. Your data must be protected from cyber-attacks like malware injection. Data must also be well protected from internal breaches. There are three critical elements of data security. They include data integrity, availability and data encryption.
More often than not, sensitive information like credit card details or health records is stored with cloud servers. Having this information deleted or tampered with can have devastating effects.
Stored data needs to be easily accessed. Sometimes cloud computing service provides store information for different organizations/client. This can cause latency in the time it takes to retrieve data. It is imperative that your data is properly isolated in a multi-tenant cloud server. This is critical when dealing with a time-bound operation.
Another way in which cloud service providers secure data is encryption. It involves the use of highly complex algorithms to encode data. The type of encryption employed depends on the data type. Encryption allows only authorized users to have access to sensitive data on the cloud. These methods of encryption include tokenization and using cryptography.
Network security: A cloud network is exposed to different types of passive and active attacks. Cloud network security uses multiple layers of protection to prevent threats. One of these is the adoption of firewalls for traffic control. Network security also employs end-end transport-level encryption between applications.
It also involves the use of encapsulated protocols such as IPSEC, SSL, and SSH while deploying a virtual private cloud. Some strategies employed in network security involves micro-segmentation or isolation of workloads. This means resources on a cloud server are made exclusive to a workload group.
Identity management: Identity and access management systems are crucial elements of cloud storage. These systems must be robust and comprehensive. Cloud computing can incorporate an organization’s IAM system to theirs or provide one of their own.
Security controls: Security controls are used by cloud networks to detect and improve areas of weakness and prevent attacks. It includes a broad range of practices and procedures and guidelines for evaluating, detecting and preventing attacks.
Deterrent controls work by warning would-be intruders or attackers about the adverse consequences they would face if the progress with their actions.
Preventive controls find vulnerabilities in the system and eliminate them. An example of this is using strong authorization on cloud users.
Detective controls simply detect and react to attacks and intrusions. They notify the corrective or preventive controls to take action. Intrusion detection and prevention agreements are used in cloud computing to detect attacks.
Corrective controls limit the damage caused by an attack. Corrective controls show during or after the attack. It also gives insight into the nature of the attack and how to prevent a reappraisal attack. Restoring and rebuilding system backup is an example of a corrective control.
Some companies hire the hacker that is specialized in cloud security, to help them enhance there cloud storage security.
Physical security: Cloud computing providers still have physical structures that have and store your data. This is the last line of defense between your data and hackers. If given access, hackers or dishonest workers can wipe and manipulate data.
This location must be well protected at all times. Their server location should be free from natural disasters. Some of these servers may be located in remote locations or other countries.
Cloud computing has clear advantages over in-house data storage. Before moving data to the cloud, organizations and businesses must consider the crucial aspects of cloud security. They must understand the cloud computing provider’s security architecture. This will allow organizations and businesses to make the right adjustments.
