The guide to protecting cloud-based systems

Learn how to protect data and infrastructure in your cloud from cyber threats. Learn more about encryption, access controls and security policies for cloud-based systems to ensure data integrity, availability and confidentiality on our topic page.

These are the most common cloud computing services

Cloud computing has established itself as a key element in the modern IT landscape. It offers a wide range of options for making companies' IT infrastructures more flexible, scalable and cost-efficient. Cloud computing is based on the principle that IT resources and services are provided and utilised via the internet instead of operating them locally on individual computers or servers within the company.

Infrastructure as a Service | Topic Cloud Security

Infrastructure as a Service (IaaS)

This is the most basic form of cloud computing. cloud computing. IaaS providers offer virtual machines, storage and network network components. Users have control over the operating system and the software installed on it, while the provider maintains the hardware. Examples include Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform. Cloud Platform.

Platform as a Service | Topic: Cloud Security

Platform as a Service (PaaS)

PaaS offers a development environment in the cloud. cloud. In addition to the infrastructure, tools for software development are are also provided. This enables developers to create, test and deploy applications without applications without having to worry about the underlying infrastructure. have to worry about the underlying infrastructure. Examples include Microsoft Azure and Heroku.

Software as a Service | Topic: Cloud Security

Software as a Service (SaaS)

SaaS applications are software products that are provided and used provided and used via the Internet. Users do not have to worry about installation and maintenance of the software, as this is done by the provider. by the provider. Well-known examples include Google Workspace, Microsoft Office 365 and Salesforce.

Cloud security - the biggest threats

Cloud systems offer enormous advantages in terms of flexibility and scalability, but also pose specific security challenges.

Philipp Kalweit, CEO of Kalweit ITS GmbH, is regarded as Germany's youngest professional hacker. With his company, he has specialised in penetration testing.

In this interview, the professional hacker explains which security gaps in cloud systems he regularly uncovers in penetration tests, how you can protect yourself against attacks on cloud systems and what you should look out for when switching to cloud services.

The challenges of cloud security

  • Data control and data protection: The distribution of data across different cloud services makes monitoring and control difficult, which brings with it data protection issues.
  • Identity and access management: It is challenging to ensure that only authorised users have access to cloud services, which requires robust authentication and access control systems.
  • Management in hybrid and multi-cloud environments: Managing security across different cloud models and providers is often challenging.
  • Endpoint security: Protecting the endpoints that access cloud services is critical to avoid vulnerabilities.
  • Cyberthreats and advanced attacks: Cloud services are attractive targets for cybercriminals. This requires a high level of vigilance and advanced security measures.
  • How can companies arm themselves against this? Find out more about the challenges and how you can prevent them here.

What cloud security solutions are available?

There are a variety of solutions in the world of cloud security, but three of the most important that are critical to most cloud environments include:

Highly magnified digital fingerprint

Identity and access management (IAM)

IAM is a central component of any cloud security strategy. It regulates who has access to which resources within the cloud environment. The core functions include user authentication, access control and authorisation management. Advanced IAM systems often use multi-factor authentication (MFA) to increase security. These systems ensure that only authorised users can access critical data and applications and reduce the risk of data leaks and other security breaches.

Cloud Security - Data Loss Prevention (DLP)

Data Loss Prevention (DLP)

Data encryption is a fundamental method of ensuring the confidentiality and security of information in the cloud. It protects data both during transmission (data in transit) and during storage (data at rest). Encryption makes it extremely difficult for unauthorised persons to access sensitive data, even if they penetrate the infrastructure. It is particularly important as data in the cloud is often moved across different networks and storage locations. Translated with DeepL.com (free version)

Firewalls and network security

Cloud-based firewalls are crucial for ensuring the security of network peripherals. They monitor and control inbound and outbound network traffic based on a defined security policy. These firewalls specialise in protecting the cloud infrastructure from unwanted access, cyberattacks and other threats. They can be configured to block or allow specific types of traffic through and play an important role in preventing data loss and theft.

Good to know - what you should know about cloud security

  • What is cloud security?
    Cloud security refers to measures and technologies for the protection of data, applications and infrastructure in cloud environments. It encompasses various aspects such as data encryption, access management, network security and compliance.
  • How secure is data storage in the cloud?
    The security of data in the cloud depends on the provider and the security measures implemented. Many cloud providers offer advanced security technologies such as encryption and robust firewalls that protect the data from unauthorised access and cyber threats.
  • What are the most common threats to cloud security?
    The most common threats include data leaks, hacker attacks, malware, insecure APIs and insider threats. Human error and a lack of security awareness can also pose risks.
  • How can I better protect my data in the cloud?
    You can protect your data by using strong passwords, activating multi-factor authentication, carrying out regular security audits and ensuring that all cloud services you use comply with the latest security standards.
  • What is the difference between public and private clouds in terms of security?
    In a public cloud, users share resources, which potentially entails more security risks. Private clouds offer more control and customised security measures, but are generally more expensive.
  • Are cloud providers responsible for the security of my data?
    While cloud providers are responsible for the security of the cloud infrastructure, the security of the data stored in the cloud is often the responsibility of the user. This model is often referred to as the "shared responsibility model".
  • Wie wirkt sich die Compliance auf Cloud-Sicherheit aus?
    Compliance plays an important role in cloud security, as organisations need to ensure that their cloud usage complies with applicable data protection laws and industry standards.
  • What are best practices for cloud security?
    Best practices include regularly reviewing security settings, training employees on security issues, using encryption, implementing strong access management and conducting penetration tests.
  • Can I use my own security software in the cloud?
    Yes, many cloud services allow users to implement their own security solutions. However, this depends on the specific guidelines of the cloud provider.
  • How do I prepare for security incidents in the cloud?
    An effective approach includes creating an incident response plan, regular backups, monitoring security logs and regularly updating security systems.
