The flow of sensitive data is visible and under control thanks to a cloud access security broker (CASB). They also detect suspicious activity and encrypt data at rest or in transit.
A CASB combines these capabilities with data loss prevention to secure sensitive information across endpoints, networks, and cloud services. As a result, it helps to mitigate external and internal threats, as well as shadow IT.
Security
Cloud access security brokers (CASBs) are policy enforcement points that consolidate and implement various security policies as cloud-based resources are accessed. They include authentication, single sign-on, authorization, credential mapping, device profiling, encryption, tokenization, logging, alerting, malware detection/prevention, and more.
CASB security is especially needed today, given the growth of cloud computing and SaaS applications and the popularity of bring-your-device (BYOD) policies. However, it has primarily expanded the data environment, making it difficult for IT teams to oversee network use and protect corporate data.
For this reason, organizations need to select a CASB solution that observes modern privacy standards and only inspects company data. They must also evaluate whether the vendor integrates with secure web gateways, application firewalls, data loss prevention tools, and email providers.
Another advantage of CASB is that it protects sensitive data in the cloud, regardless of where it is stored. In addition, it can encrypt data at rest and in transit, scrambling information, so it’s unusable by an attacker.
In addition, CASBs can help reduce the risk of shadow IT, which is applications and infrastructure that are managed and used without an organization’s IT department knowing about it. They can provide visibility into these unauthorized assets and offer automated recommendations on preventing them from becoming a problem.
Visibility
Visibility is an essential pillar of security. It allows you to see what’s happening within your organization’s cybersecurity ecosystem so that you may take the necessary actions to safeguard sensitive information and avoid a data breach.
A CASB solution can help you gain visibility into your applications and the users who access them. It can also help you detect suspicious authentication attempts and data loss prevention alerts so that you can quickly address any issues.
It’s essential to choose a CASB solution that is tailored to your specific business needs. In addition, ensuring you’re getting the right security solutions and benefits from your CASB solution is necessary.
CASB vendors typically offer coverage across many cloud service delivery models, including SaaS, platform (PaaS), and infrastructure (IaaS). Most CASBs support the most popular SaaS applications, like content collaboration platforms, CRM systems, HR systems, ERPs, service desks, office productivity suites, and enterprise social networking sites.
CASB security is essential for organizations that want to safeguard their most valuable data and remain secure in the cloud.
Compliance
CASB security is essential to any cloud-based solution involving sensitive data. It allows security teams to control access to this information through authorization policies and prevents unauthorized sharing of sensitive data such as credit card numbers, health records, or social security numbers.
Besides authentication and authorization, a CASB should offer cloud data loss prevention (DLP) capabilities. These include detecting if sensitive information is shared in public or external links and encrypting data at rest in the cloud.
A CASB will also block malware and ransomware that can be installed on devices in the cloud or on-premises. These threats can compromise sensitive corporate information and disrupt the operation of cloud services.
Another significant benefit of a CASB is its visibility into an organization’s cloud usage. This visibility allows IT teams to monitor unsanctioned cloud applications, a growing issue for many organizations.
CASBs are an intermediary between cloud services and the organization’s on-premises IAM tools, providing visibility into cloud usage and associated risks. It allows IT to make informed decisions about granting users access and monitoring their use. Moreover, it helps them to identify suspicious cloud activity and automatically remediate breaches. As a result, IT can keep their enterprise’s cloud usage safe without compromising productivity and efficiency.
Cost
Having a CASB security solution is not only an effective way to mitigate data breaches and other threats, but it can also save your business money. It can help you reduce the number of cloud services your organization uses, and it will also allow you better to manage risk and compliance across the entire cloud ecosystem.
In addition, a CASB can protect your organization’s assets and infrastructure from malware and other threats.
A CASB can identify misconfigurations and help you remediate them quickly. It can also help encrypt your data and control personal devices and mobile applications.
With a CASB, you can protect your organization’s data and infrastructure from threats and malware that can access it in the cloud or on-premises. It can also monitor and alert you when suspicious activities happen, such as stolen credentials or lost laptops.
Consider how a CASB will integrate with your existing systems when assessing it. It will help determine whether it offers the necessary functionality to meet your business’s needs. It will also ensure that the solution can grow and change to accommodate new threats as they develop.
