IT is undergoing significant changes for large companies, as evidenced by the increasing migration to cloud services. With that in mind, here are some suggestions on how companies can minimize the risk of data breaches with a good cloud strategy.
1. Don't target your data
Think of strategies to minimize data values in terms of attractiveness as a goal. Consider using services in a virtual private cloud or on-site / on-site systems that are completely behind the firewall so that the information is not in the spotlight of very visible SaaS targets.
2. Protect user identity and company metadata
The user's identity is the target of the attack: the company needs to protect it because successful attacks tend to result in the loss of the user's company data. Similarly, when someone learns about the existence of data and knows its characteristics, it can pose a threat to data security itself.
Some cloud storage providers fail to comply with this code, maintaining the metadata of all their customers in one place, indirectly requiring companies to hand over their fate to their own hands. Logically, this poses a significant risk to data confidentiality and integrity.
3. Avoid SaaS providers that generate themselves and / or manage encryption keys
Encryption keys generated on unencrypted servers can help attackers gain access to your company data. Even if you entrust your SaaS provider with your key management, the risk of losing control of your data increases.
While cloud service providers promote their high security standards, such as physical site hosting protection, electronic monitoring, and ISO 27001 certification, many still fail to protect the requirements of government data, request court data without owner information, and covert espionage attacks. Be sure to still control the user's identity, metadata, and encryption keys to protect your data.
4. Control your endpoints and branches
Use Enterprise Mobility Management Tools (EMM) to prevent the appearance of IT shadows and provide safe work on company-owned BYOD devices. Encrypt all existing data in the place of origin to protect your files from unauthorized access.
5. Limit access to external employees
Use strict policies that determine what data is uploaded in a file-sharing environment and to the domain / e-mail address where e-mails can be sent. Record all access to identify extraordinary events.
6. Increase password security
Apply strong password strength and refresher guidelines. Consider multi-factor authentication, which requires users to enter using a combination of data they know.
This can be a strong password or something they have, such as a smart card or token that generates a password once.
7. Know your privacy
You must understand the limitations of cloud services when returning data that is lost due to attacks, user errors, or other causes. This is part of the service level agreement (SLA) of each provider.
Protect your data in the cloud by securing your SaaS applications and services and applications running on public cloud infrastructure as a service (IaaS). This must be part of the company's backup and recovery strategy for data at all sites (in locations and in the cloud).
8. Learn about multi-cloud strategies
Running applications on many cloud services, not just one provider reduces the risk of service outages. This can cause significant problems and downtime. This is an important part of cloud strategy that allows organizations to maintain their freedom to choose the cloud while ensuring business continuity.
