Does your business use cloud services, whether for storage, collaboration, analysis, or business workflows? Or, are you aware that your employees use it?
Although software developers create cloud services with a view to making it as secure as possible, vulnerabilities still exist. At GA Systems, we recognise that the way your organisation interacts with cloud services can present security flaws. Similarly, the clouds you use might not meet your usual network security standards.
With both of those factors in mind, it’s worth considering the use of a Cloud Access Security Broker (CASB). CASBs act as a form of security that bridge the gap between clouds and your network’s existing systems. To decide whether using one is right for your company, it’s worth learning what they are and how they work.
To achieve our CASB goals, the team at GA Systems has partners with the Gartner leading providers to form a robust security solution that ensures your cloud usage remains safe. We have a long-standing history of using 360-degree data protection without slowing down the way businesses use cloud services. While ensuring your Internet use remains flexible, GA Systems deploys the right cloud security solution to cover your security blind spots.
Cloud Access Security Broker Definition
The basic definition of a cloud access security broker is that it’s a software tool that works as a gatekeeper between cloud service providers and their customers to reduce security risks. If you or your employees use cloud services for storage, collaboration, analysis or workflows, the CASB will monitor any activity that takes place and extend security controls. Throughout the process, it will gather data, turn it into analytics, and then highlight security risks.
No two CASBs are made the same and the team here at GA Systems works hard to create solutions that match your company’s needs. Some of the features we can incorporate include:
- Monitoring what users are doing throughout your organisation. This includes how they use the cloud services and the devices they’re using it on.
- Round the clock alerting for sanctioned or unsanctioned cloud services supporting your security team.
- Monitoring from a 360-degree protection perspective that guards data everywhere, and advanced threat protection that stops elusive attacks.
- The enforcement of current policies. For example, if the system detects an action that violates your company’s security controls for cloud services and how you want the clour to be used, it can produce a warning and block the action so that the user is aware of what’s happening.
- Automatically preventing malware. Unfortunately, cloud services are a prime target for those who want to introduce malware to networks. By detecting malware as it attempts to enter your system, we can stop it from having a negative effect.
The GA Systems team can also introduce advanced cloud access security broker services. This includes single user sign on and the tracking of authorisation credentials. Tracking authorisation credentials can identify patterns amongst those who attempt to access information they’re not usually privy to. After liaising with our team, you can help us agree on the CASB control that presents the right alerting for your operational environment. Taking the collaborative approach is essential to providing full coverage whether a browser, mobile app, desktop app or sync client.
Cloud Access Security Broker Services
All good cloud access security broker services will include the four pillars of CASB. They include:
Choosing to implement a blanket ‘block’ or ‘allow’ system can slow your day-to-day operations down. Rather than taking this approach, the team at GA Systems prefers to adjust access permissions according to security risks. For example, if you use Outlook for emails, you may want to allow full access in the office to everyone. You might also eventually realise that some individuals need to access their emails remotely and so you could use your CASB to grant those rights. Ongoing reviews of your CASB will allow you to make similar changes as your company evolves.
The need to comply with local and national legislation with regards to data privacy is always increasing. Using a cloud access security broker, you can automatically make sure this happens.
Strengthening data security
Your data is at its most vulnerable when it moves in and out of the cloud. Using advanced detection mechanisms, including fingerprinting, it’s possible to identify security threats while data is transitioning. The CASB will then give your onsite IT team the chance to intervene if they feel it’s necessary.
Real-time threat protection
It’s often the case that security threats arise from mishaps rather than ill intent. For example, an employee could accidentally introduce malware to the cloud or your onsite network through what they upload or download. Although such instances are accidental, they’re also harmful.
Your CASB will scan and tackle threats as they arise. As a result, the live transition of data becomes safer and you don’t have to slow down your business activities to use the cloud in a secure manner.
Overall, your cloud access security broker can manage risks, deliver security, or do both. In many cases, those who use a CASB opt for both in order to streamline their network’s security.
More refined examples of how a CASB can work include:
Governing cloud usage
Governing the use of cloud services involves looking at the smaller details behind what a user does and what you will allow them to do. It’s more refined than simply allowing access or blocking activities. It’s also an excellent means of using a cloud securely while adhering to your organisation’s policies.
The more often your company’s data transitions between your network and a cloud, the higher its risk of encountering vulnerabilities. You can use a CASB to reduce the chances of sensitive data getting lost during these transitions. This applies to reducing the chances of external individuals seeing sensitive information and limiting the risk of unauthorised access within your organisation. You can use a CASB to introduce security measures onsite, for remote use, and on specific devices.
Malware and ransomware are only getting smarter, which means you need a reliable form of threat protection. CASB services that deliver threat protection will provide full visibility of cloud services, they’ll encrypt connections, produce data that identifies risks, and automatically tackle certain security flaws.
If your company uses cloud services, now’s the time to consider whether a cloud access security broker is necessary for you to remain secure. In addition to keeping information safe, the right CASB will help you work faster. When refined threat detection processes replace simple block and access approaches, your cloud usage becomes more fluid. To learn more, contact the GA Systems team.
