Beginner's Guide to Cloud Security

Cloud Security: A Complete Guide for Beginners

Cloud technology has opened up a whole new era in IT solutions in terms of storage, flexibility, accessibility, and productivity. As the cloud gives the provision of shared resources, it brings along the new overheads of security concerns. Not only sharing features but also its identity management, access control, and privacy are the points of concern. Thus for organizations using cloud computing as well as for the cloud vendors providing services – cloud security is a high priority.

Certificate of Cloud Security Knowledge

In this blog, we will cover what is cloud security and the different aspects of cloud security like possible risks, challenges, and solutions. Also, we will have a look over the list of the most in-demand cloud security certification.

What is Cloud Security?

Cloud security is similar to IT security in on-premises data centers. However, it does not need any hardware or maintenance facility. Cloud security solutions are provided using software tools that protect and monitor the information flow in the cloud resources. Hence, there is no need for physical storage devices or servers. Using various security measures, we can prevent data theft, data leakage, and unwanted data deletion.

In a broad sense, cloud security is a subdomain of information security which comprises the computer and network security. However, it has its own set of policies, controls, and technologies to protect cloud data, applications, and infrastructure.

What are the Various Cloud Security Risks?

Cloud security challenges may come in different ways. The most vulnerable are as below:

1. Account Hijack

Account hijack is a growing threat in the IT industry due to open access to the cloud platform. It has enhanced credential compromise like login details by attackers to make them successful in accessing sensitive user information in the cloud. Moreover, they can manipulate the information using the hijacked credentials. Sometimes hijackers use the cloud for stealing credentials by injecting cross-site scripting bug.

2. Insider Threat

Every company maintains some quality control measures in terms of its process, data security, data sharing, and access. When any violation happens to that by the employees, it is called an insider threat. Though it is very unlikely to happen inside an organization, the insider threat is a viable security issue in the cloud. In such a scenario, an employee can misuse his authorized access to access organization’s cloud-based services such as customer accounts, financial information, and other sensitive information.

3. Malware Injection

Malware injections are the code or scripts which are used for malicious activities in the cloud. They are embedded into valid instances of cloud services and run as Software as a Service (SaaS) to cloud servers. Once such code or scripts are injected, it starts executing and utilizing it. Attackers can compromise the sensitive information along with stealing data. 

4. Abuse of Cloud Services

As the cloud leverages the extended facility of storage and services, enterprises whether small or large host a vast amount of data in the cloud. However, this storage solution also allows hosting illegal software, and other digital contents. Consequently it sometimes adversely affect the cloud service providers and their clients. In most of the cases, such contents include pirated software, music, videos or books.

5. Insecure APIs

Application Programming Interfaces (API) is the means to customize the features of cloud services to enhance user cloud experience. Programmers build their own programs and integrate those applications with cloud services for better performance. However, sometimes these APIs are used for authentication, accessibility and encryption purposes, and that’s where the vulnerability lies with it. This increases the security risks.

6. Denial of Service Attacks (DoS)

Denials of Service (DoS) attacks are the kind of cyber attack that does not target to breach the sensitive information. However, they carry long-term effects like making a website and servers unavailable. In addition to that, sometimes it turns down firewalls to perform malicious activities.

7. Data Breaches

Data breaches are the common problem in IT for years. With the cloud, this problem is more highlighted as the cloud offer open access to data stored online. There are different types of data breaches that happen in cloud platform which is displayed in the below chart.

Data Breaches

As per the market survey report, data breach occurrence happens 3 times more in the organizations that use cloud than those of the others. This is because of the cloud’s unique set of characteristics which makes it more vulnerable.

8. Insufficient Due Diligence

Apart from the technical security concern, security issue can arise due to incorrect cloud strategy. This means when an organization is not clear about its policies, organizational goals, and resources, that causes insufficient due diligence which creates the security risk for the company.

9. Shared Vulnerabilities

The security of cloud is a shared goal for the provider and the client. Here the partnership is between the client and the provider where the client needs to take preventive measures to protect data. In case this shared responsibility is omitted, there is a high possibility of comprising security.

10. Data Loss

Cloud service provider must have a proper data recovery plan. The reason behind is that there is a high chance of data loss on cloud services due to:

  • Malicious attack
  • Natural disaster
  • Data removal by the provider

An organization can lose vital information along with these lost data, and it could badly impact an organization. Hence, verifying the provider’s data backup policy is an utmost importance as it is related to physical storage, access, and geographical location of the data centers.
