**CASB Selection**
When selecting a CASB tool, it is essential to consider its compatibility with your existing cloud infrastructure. Integration capabilities with popular cloud service providers, such as AWS, Azure, or Google Cloud, are crucial for seamless deployment and management. Additionally, the CASB solution’s scalability and ease of deployment are factors to consider to ensure minimal disruption to your existing cloud environment.
Secure cloud-based applications and services with Cloud Access Security Brokers (CASB). These solutions, typically deployed between cloud service consumers and providers, allow organizations to enforce security policies and gain visibility into cloud usage.
1. Visibility
Both managed and unmanaged cloud services require visibility and control. Instead of allowing or blocking all cloud services, cloud brokerage should enable IT to say “yes” to valuable services while controlling access to their activities. For users on unmanaged devices, this could mean offering Web-only email access instead of a sanctioned suite like Microsoft 365. A “no sharing outside the company” policy could also be enforced across an unsanctioned service category.
Security is the primary focus of cloud access security brokers, but they can also help you understand cloud spending. With a CASB, you can discover all cloud services in use, report on your cloud spend, and uncover redundancies in functionality and license costs. In addition to protecting your business and finances, a CASB can provide valuable information.
2. Compliance
Moving data and systems to the cloud requires organizations to consider compliance. If these compliance standards are ignored, data breaches can be costly and dangerous, as they ensure the safety of personal and corporate data.
If you are a healthcare organization concerned about HIPAA or HITECH compliance, a retail company concerned about PCI compliance, or a financial services organization concerned about FFIEC and FINRA compliance, cloud access security brokers can help ensure compliance. Through a CASB, you can keep your company in compliance with industry-specific data regulations and avoid costly data breaches.
3. Data Security
Accuracy can be achieved by using highly sophisticated cloud DLP detection mechanisms like document fingerprinting and reducing the detection surface area (user, location, activity, etc.). A cloud access security broker (CASB) should provide IT with the option to move suspected violations to their on-premises systems for further analysis when sensitive content is discovered in the cloud or on its way there.
CASBs can act as gatekeepers and facilitate the detection and prevention of malicious activity before it escalates. They can carry out more profound research on threat observations. CASBs are IT and business practices experts and take a skilled approach to enhancing an organization’s security.
4. Threat Protection
Organizations should ensure their employees are not introducing or propagating cloud malware and threats by using cloud storage services and their associated sync clients and services. An employee trying to share or upload an infected file should be able to scan and remediate threats in real-time across internal and external networks. In addition, this means detecting and preventing unauthorized access to cloud services and data, which can assist in identifying compromised accounts.
CASBs can protect organizations from cloud threats and malware. Your company must avoid threats that combine prioritized static and dynamic malware analysis for advanced threat intelligence. Proper threat protection can help protect you from threats that originate from or are propagated through cloud services.
**Network Security Components**
Recently, when I spoke to Sorell Slaymaker, we agreed that every technology has its own time and place. Often, a specific product set is forcefully molded to perform all tasks. This carries along with its problems. For example, no matter how modified the Next-Gen firewall is, it cannot provide total security. As you know, we need other products for implementing network security, such as a proxy or a cloud access security broker (CASB API) to work alongside the Next-Gen firewall and zero trust technologies, such as single packet authorization to complete the whole picture.

A cloud access security broker (CASB) allows you to move to the cloud safely. It protects your cloud users, data, and apps that can enable identity security. With a CASB, you can more quickly combat data breaches while meeting compliance regulations.
For example, Cisco has a CASB in its SASE Umbrella solution that exposes shadow IT by enabling the detection and reporting of cloud applications across your organization. For discovered apps, you can view details on the risk level and block or control usage to manage cloud adoption better and reduce risk.
Introducing CASB API Security
Network security components are essential for safeguarding business data. As most data exchange is commonplace in business, APIs are also widely leveraged. An application programming interface (API) is a standard way of exchanging data between systems, typically over an HTTP/S connection. An API call is a predefined way of obtaining access to specific types of information kept in the data fields.
However, with the acceleration of API communication in the digital world, API security and CASB API mark a critical moment as data is being passed everywhere. The rapid growth of API communication has resulted in many teams being unprepared. Although performing API integrations is easy, along with that comes the challenging part of ensuring proper authentication, authorization, and accounting (AAA).
When you initiate an API, there is a potential to open up calls to over 200 data fields. Certain external partners may need access to some, while others may require access to all.
That means a clear and concise understanding of data patterns, and access is critical for data loss prevention. Essentially, bad actors are more sophisticated than ever, and simply understanding data authorization is not enough to guard the castle of your data. A lack of data security can cause massive business management and financial losses.
CASB Tools: The challenge
Many enterprise security groups struggle to control shadow IT. One example is managing all Amazon Web Services (AWS) accounts, where AWS employs tools like Macie for API management. However, these tools work well only for AWS accounts for which Macie is turned on. Enterprises can have hundreds of test and development accounts with a high risk of data leakage, of which the security teams are unaware.
Also, containers and microservices often use transport layer security (TLS) connections to establish secure connectivity, but this falls short in several ways. Examining the world of API security poses the biggest challenge that needs to be solved in the years to come. So what’s the solution?
CASB Tools and CASB API: The Way Forward
Let’s face it! The digital economy is run by APIs, which permit the exchange of data that needs to be managed. API security tools have become a top priority with the acceleration of API communication. We don’t want private, confidential, and regulated data to leave that is not supposed to go, and we need to account for data that does go. If you don’t have something in the middle and encrypt just the connections, data can flow in and out without any governance and compliance.
API Security Tools
Ideally, a turnkey product that manages API security in real-time independent of the platform—in the cloud, hybrid, or on-premise—is the next technological evolution of the API security tool market. Authentically, having an API platform across the entire environment and enforcing real-time security with analytics empowers administrators to control data movements and access. Currently, API security tools fall into three different types of markets.
- Cloud Access Security Brokers: The CASB API security is between an enterprise and the cloud-hosted services, such as O365, SFDC, ADP, or another enterprise
- API Management Platforms: They focus on creating, publishing, and protecting an API. Development teams that create APIs consumed internally and externally rely on these tools as they write applications. You can check out the Royal Cyber blog to learn about API management platforms like IMB API Connect, MuleSoft, Apigee API, and MS Azure API.
- Proxy Management focuses on decrypting all enterprise traffic, scanning, and reporting anomalies. Different solutions are typically used for various types of traffic, such as web and email. Chat is an example.
Cloud Access Security Brokers
The rise of CASB occurred due to inadequacies of the traditional WAF, Web Security Gateway, and Next-Gen Firewalls product ranges. The challenge with these conventional products is that they work more as a service than at the data level.
They operate at the HTTP/S layer, usually not classifying and parsing the data. Their protection target is different from that of a CASB. Let’s understand it more closely. If you parse the data, you can classify it. Then, you have rules to define the policy, access, and the ability to carry out analytics. As the CASB solutions mature, they will become more automated.
They can automatically discover API, map, classify, and learn intelligently. The CASBs provide a central location for policy and governance. They sit as a boundary between the entities. They are backed by the prerequisite to decrypt the traffic, TLS, or IPSec. After decrypting, they read, parse, and then re-encrypt the traffic to send it on its way.
Tokenization
When you are in the middle, you need to decrypt the traffic and then parse it to examine and classify all the data. Once it is classified, if there are specific susceptible data, be it private, confidential, or regulated, you can tokenize or redact it at a field and file level. Many organizations previously created a TLS or IPsec connection between themselves and the cloud provider or third-party network.
However, they didn’t have strict governance or compliance capabilities to control and track the data going in and out of the organization. TLS or IPsec is the only point-to-point encryption; the traffic is decrypted once you reach the end location. As a result, sensitive data is then available, which could be in an unsecured network.
Additional security controls are needed so that the data has an extra level of encryption when the connections are complete. TLS or IPSec is for the data in motion, and tokenization is for the data at rest. We have several ways to secure data, and tokenization is one of them. Others include encryption with either provider-managed keys or customer BYOK.
We also have different application-layer encryption. Tokenization substitutes the sensitive data element with a non-sensitive equivalent, a token. As a result, the third party needs additional credentials to see that data.
However, when you send the data out to a 3rd party, you add another layer of encryption by putting in a token instead of a specific number like the social security number. Redact means that the data is not allowed to leave the enterprise.
CASB API Security
For API security, AAA is at an API layer. This differs from the well-known AAA model used for traditional network access control (NAC). Typically, you allow IP addresses and port numbers in the network world. In an API world, we are at the server and service layer.
– Data Loss Prevention (DLP) is a common add-on feature for CSBs. Once you parse and classify the data, you can govern it. Here, the primary concern is what data can be left, who can access it, and when. DLP is an entire market, whereas the CASB will be specific to specific APIs.
– It would be best if you often had a different DLP solution, for example, to scan your Word documents. Some vendors bundle DLP and CASB. We see this with the Cisco Umbrella, where the CASB and DLP engines are on the same platform.
– Presently, the next-generation CASBs are becoming more application-specific. They now have the specific capability for Office 365 and SalesForce. The market constantly evolves; it will integrate with metadata management over time.
Example IDS Technology: Suricate
API Management Platforms
API Management platforms are used by DevOps teams when they are creating, publishing, and protecting their APIs. DevOps creates an API that is consumed internally and externally to enable their application to rely on these tools. In an enterprise, had everyone been using an effective API management tool, you wouldn’t need a CASB. One of the main reasons for introducing CASBs is that you have a lot of development and test environments that lack good security tools. As a result, you need the 3rd tool to ensure governance and compliance.
Finally, Proxy Management
A proxy monitors all the traffic going in and out of the organization. A standard proxy keeps a tab on the traffic moving internally to the site. A reverse proxy is the opposite, i.e., an external organization looking for internal access to systems. A proxy operates at Layer 5 and Layer 6. It controls and logs what the site users are doing but does not go into layer 7, where all the critical data is.
