In recent years, many organizations have moved a significant portion of their infrastructure to the cloud. This transition has brought with it clear benefits of flexibility, availability, and cost savings, but has also exposed organizations to risks that did not exist when everything ran in-house. Therefore, cloud security is not an add-on but a fundamental part of any responsible cloud deployment. The main challenges, recommended practices, and factors to consider before moving data and processes to a cloud environment require professional preparation in advance.
Cloud information security benefits
Cloud information security allows organizations to benefit from advantages that are difficult to achieve in on-premises environments. Working with a provider that operates multiple data centers ensures high availability and quick recovery in case of a regional failure. Cloud security solutions are built to comply with international standards like ISO 27001 for information security management and ISO 9001 for quality management, providing the organization with a controlled and recognized foundation with customers and business partners. Cloud-based backup solutions enable broad protection of data and organizational mailboxes, with fast recovery capabilities in case of a cyber event or data loss. Cloud-based managed monitoring solutions, SIEM and SOC, enable real-time threat detection and rapid response to security incidents. Working with a partner familiar with the Israeli environment, providing service in Hebrew, and operating on Israel time is a significant advantage when it comes to event response and compliance with local regulatory requirements.
The main challenges in security management in a cloud environment
Identity and Access Management: As many services operate in the cloud, the number of digital identities grows accordingly: employees, automated systems, APIs, and external vendors. Each of these can be an entry point if its permissions are not configured correctly. The principle of least privilege, meaning granting each entity only the access it truly needs, is one of the fundamental principles that significantly reduces risk. Organizations that do not implement this principle may find themselves with dozens of accounts that have broad access privileges, some of which are no longer in use but are still open to attack.
In a local environment, anomalous network behavior can often be identified. In the cloud, data flows between many services, and there isn't always a complete picture of what's happening. Without appropriate monitoring tools, it's difficult to detect intrusion attempts, unauthorized access, or data leakage in real-time. This is where SIEM solutions come into play, enabling the collection, analysis, and response to security events from multiple sources in a hybrid or fully cloud environment. Continuous monitoring is the difference between early threat detection and discovering a breach only after the damage has already been done.
Organizational responsibility for regulatory compliance remains even when moving to the cloud.
Compliance with regulations: Organizations in regulated fields such as finance, health, insurance, and critical infrastructure are required to comply with regulatory requirements even when their data is stored on external vendor servers. Moving to the cloud does not exempt organizations from complying with GDPR, relevant ISO standards, or Israeli regulations that apply to the organization. Sometimes, explicit approval is required regarding the geographic location of data storage, which necessitates a deep understanding of the service terms with the cloud provider even before implementation.
Protection begins with proper backup
Cloud file backup is often the first element organizations adopt, sometimes without realizing it also requires security attention. A backup stored in the cloud that is not encrypted, not isolated, and not protected by appropriate access controls, may become an attractive target for an attack. A proper backup is an encrypted backup, stored separately from the production environment, and adhering to predetermined frequency and policies. In addition, it is important to ensure that the restore process is actually tested and not just documented on paper, because a backup from which a restore cannot be performed does not fulfill its purpose.
Information security in an organization in a hybrid cloud environment
Most organizations don't move to the cloud all at once but manage a hybrid environment where some systems still run on-premises and some in the cloud. Management Information security in an organization This is more complex because defense perimeters are unclear and data moves between environments. Building a unified policy that spans both environments, with tools that provide full visibility into both, is the way to effectively reduce risks. Organizations that manage each environment separately with different tools often lose the necessary visibility to identify threats that move between environments and may go unnoticed.
Cloud Security Best Practices
There isn't one solution that fits every organization, but there are several principles that prove themselves in most cases and should be implemented in any cloud environment.
Encrypting data in transit and at rest is a basic layer of protection that ensures even if an unauthorized party manages to access the information, they won't be able to read it.
✔ Multi-factor authentication (MFA) on every account with access to the cloud environment is a simple step to implement and significantly reduces the risk of a breach through leaked credentials.
Continuous monitoring and log centralization allow for the identification of anomalous behavior even before it becomes a full-blown security incident.
Regular checks of permissions and security settings often reveal outdated, forgotten settings that remain open to external access.
Preparing an incident response plan in advance, including clear procedures and defined roles, significantly shortens response time when a real incident occurs.
Cloud information security starts with choosing a professional partner
Migrating to the cloud is a significant step that requires professional thought, organized preparation, and the right choice of a partner. Ofek Dist specializes in guiding organizations and marketers through the cloud migration process, ensuring that every protection layer is correctly configured from day one. The experience gained from working with hundreds of business partners over the years allows us to identify common vulnerabilities and address them before they become incidents. In an environment where threats evolve rapidly, having a partner who knows the Israeli technological and regulatory landscape is a significant advantage.

Frequently Asked Questions about Cloud Information Security:
What is the difference between cloud provider responsibility and organizational responsibility?
The cloud provider is responsible for the physical infrastructure and the basic operating layer. The organization is responsible for data, identity management, access settings, and protecting applications running in the environment. A common mistake is to assume the provider handles everything.
Is cloud backup sufficient for protection?
Not necessarily. A backup that is not encrypted, not isolated from the production environment, and not tested for actual restoration does not fulfill its purpose. Proper backup includes encryption, access controls, and periodic restoration tests.
How do you manage security in a hybrid environment where some systems are in the cloud and some are on-premises?
A uniform policy that spans both environments must be built with monitoring tools that provide full visibility into both. Managing each environment separately creates blindness that allows threats to move between environments undetected.
Does moving to the cloud exempt an organization from complying with regulations?
No. The organization is required to comply with all relevant regulations even when the data is stored by a third-party provider. In some cases, explicit approval is also required regarding the geographical location of data storage.
What is the single step that reduces the most risk in a cloud environment?
Multi-factor authentication for all accounts with cloud environment access. This is a relatively simple step to implement that dramatically reduces the risk of a breach through compromised accounts.
