16 Cloud Security Best Practices
Micro-segmentation creates secure zones in data centers and cloud deployments thereby segmenting workloads from each other, securing everything inside the zone, and applying policies to secure traffic between zones. Machine learning and artificial intelligence extend contextual awareness technologies across a cloud security portfolio. With cloud security, businesses have protection across IaaS, PaaS, and SaaS, extending security to the network, hardware, chip, operating system, storage, and application layers. Segmentation of services can help an organization control how their data is accessed and stored. Consider a vulnerability management solution that can continuously scan workloads for vulnerabilities, compile reports and present the results in dashboards, and auto-remediate problems where possible. When making the initial foray into the cloud, there are some non-negotiable security constructs that come into play. Customers should always check with their CSPs to understand what the provider covers and what they need to do themselves to protect the organization. Reading the TOS is essential to understanding if you are receiving exactly what you want and need. Innovate with a wide portfolio of security services and partner solutions to help achieve end-to-end security for your organization. Organizations require powerful capabilities, designed and built by experts, which encode years of experience, knowledge and best practices, all available at their fingertips. The way to approach cloud security is different for every organization and can be dependent on several variables. However, the National Institute of Standards and Technology (NIST) has made a list of best practices that can be followed to establish a secure and sustainable cloud computing framework. The Zero Trust (aka assume breach) approach is the gold standard for enabling cloud security. For example, restrict workload deployment using public IPs, contain east-west traffic flow, or implement monitoring of container workload traffic patterns.

Organizations are adopting cloud platforms for their mission-critical workloads more than ever, thanks to the flexibility and efficiency provided by the cloud in comparison to traditional data centers. Developers on AWS You can either encrypt your data yourself before storing it on the cloud, or you can use a cloud provider that will encrypt your data as part of the service. However, if you are only using the cloud to store non-sensitive data such as corporate graphics or videos, end-to-end encryption might be overkill. On the other hand, for financial, confidential, or commercially sensitive information, it is vital. Identity management methods like data masking have been used to separate identifiable features from user data for GDPR compliance. For HIPAA compliance, organizations like healthcare facilities must make sure that their provider does their part in restricting data access as well. Zero Trust, for example, promotes a least privilege governance strategy whereby users are only given access to the resources they need to perform their duties. Similarly, it calls upon developers to ensure that web-facing applications are properly secured. For example, if the developer has not blocked ports consistently or has not implemented permissions on an “as needed” basis, a hacker who takes over the application will have privileges to retrieve and modify data from the database. So, whether you are an individual user, SMB user, or even Enterprise level cloud user — it is important to make sure that your network and devices are as secure as possible. This starts with having a good understanding of basic cyber security on an individual user level, as well as, ensuring that your network and all devices are protected using a robust security solution that is built for the cloud. Encryption Vulnerabilities Identity and access management (IAM) pertains to the accessibility privileges offered to user accounts. Access controls are pivotal to restrict users — both legitimate and malicious — from entering and compromising sensitive data and systems. Password management, multi-factor authentication, and other methods fall in the scope of IAM. Whether your data and applications live in the public cloud, a private cloud, or a hybrid of the two, they need protection. Providers ensure that all critical data (credit card numbers, for example) are masked or encrypted and that only authorized users have access to data in its entirety. Moreover, digital identities and credentials must be protected as should any data that the provider collects or produces about customer activity in the cloud. Reading the TOS is essential to understanding if you are receiving exactly what you want and need. Encryption scrambles your data so that it’s only readable by someone who has the encryption key. For example, CSPs with SaaS-based offerings may or may not offer customers visibility into the security tools they use. Companies have to constantly remind their employees to keep constant vigilance especially remotely. Legislation has been put in place to help protect end users from the sale and sharing of their sensitive data. Cloud computing is the delivery of hosted services, including software, hardware, and storage, over the Internet. Taking the initiative to educate yourself on how to protect the data you have stored in the cloud starts with knowing what you’re protecting it from. Here is a list of common cloud security risks and concerns that threaten the Cyber Safety of your digital assets. Cloud security, also known as cloud computing security, is the practice of protecting cloud-based data, applications and infrastructure from cyber attacks and cyber threats. How to Secure Your Cloud Computing Environment After all, your files, photos, and videos are being stored on servers that are not under your control. A major benefit of the cloud is that it centralizes applications and data and centralizes the security of those applications and data as well. Eliminating the need for dedicated hardware also reduces organizations’ cost and management needs, while increasing reliability, scalability and flexibility. Putting the right cloud security mechanisms and policies in place is critical to prevent breaches and data loss, avoid noncompliance and fines, and maintain business continuity (BC).
