The cloud computing market has been fully formed, and security needs have become the biggest key point. As we all know, the network is the most overlooked security risk. For cloud computing, understanding user behavior is essential to ensure safe use and collaboration.
Today, many chief information security officers are calling for people to face the security needs of cloud computing. However, although everyone has a common focus, the approach taken is different; some people call for protection on the server side, while others want to focus on the uploading, downloading, and Safety education in areas such as collaboration, which often results in a series of new restrictions and monitoring policies. While these methods are usually built around servers, new ways to make user cloud platforms more secure should be a top priority for optimizing cloud security.
1. Protecting devices is as important as protecting access to cloud services
No one seems to deny the fact that operating system (OS) providers are most effective in terms of device protection, and these providers can handle almost all violations in zero-day time. The number of mobile devices that staff use to access organizational resources is increasing, and security vulnerabilities such as theft, human negligence, or irresponsibility are emerging. For example, if a device is already populated with a virus or has been loaded with some illegal applications, all cloud services accessed by that device may be compromised.
One might think that strengthening user education is enough to solve this problem, and users need to be responsible for their actions. However, even the most responsible and secure user is still a risk factor. Moreover, even if the user's own device is safe, it is still in a dangerous area. Users may have unsafe behaviors such as downloading sensitive data to the device, using an external computer with a keylogger installed, and reloading the application to a private device.
Therefore, any of these behaviors will make it easier for a malicious person to crack the device and embed the program in a way that may not be recognized and will not be detected by the user - at least until it is too late. Implant, load, disable encryption, password cleanup, and unpatched operating systems are some of the risks that will be brought to devices, proxies, and cloud applications. Organizations that want to have strong cloud protection capabilities need to understand the security status of the device and the ability to identify the risk.
2. The network is the most overlooked security risk
However, protecting devices and the cloud does not mean that the networks that connect to them are not compromised. Today's workplaces are more flexible, and workers are more likely to work remotely in public. Wireless networks come in many forms: some wireless networks are easy to identify and classify in terms of security risks, while others are grayed out and people are not familiar with them. Users do not always pay enough attention to the networks they are connected to. Sometimes users don't really understand the dangers, sometimes they only focus on finding the fastest way to connect to the network so they can continue working. Staff are usually connected directly to the corporate cloud platform via a coffee shop, hotel room, and public network at the airport. Unfamiliar network connections make it difficult for users to guard against hackers, which can put risks on the enterprise cloud platform and the entire cloud security chain. The network seems to be the weakest part of the secure link.
Unfortunately, many people think that rejecting any public network access is the ultimate solution, but is this a realistic approach? Employees using proprietary devices are always looking for the easiest and most convenient solution, and even after experiencing a bad user experience, they will continue to find ways to bypass network security restrictions. It is also a misleading fact that all public networks are risky, and in fact not all open networks are malicious. There are built-in safeguards when each end of the network (device and cloud) is connected, and these security measures are rare on the network itself.
Therefore, it is important to monitor network behavior and quickly and thoroughly analyze suspicious networks in order to identify malicious networks before any damage occurs. Protecting the cloud platform requires a posture that protects the network to ensure continued trust for all users, which means protection from security and encryption settings to the routing path of the IP network. After all, if the device is connected to a threatened network, then the network can be used to steal user credentials, steal corporate data or delete encryption. What are the benefits of using such a network?
3. Understanding user behavior is critical to ensuring safe use and collaboration
When discussing any security issue, malicious actors seem to be a starting point, but the internal threats that companies face should be real security priorities. Some users' intentions are not malicious, but some of their unintentional behavior is dangerous. Some users don't even know that their actions may have an impact on their operations. A user profile can be divided into three parts: user role, user behavior, and collaboration mode.
The user's role is an important aspect of permissions, access rights, and reasonable behavior. A good security access strategy will help. For example, while administrators can be granted broad access, they should not be allowed access to AWS from non-company networks. Marketers may not be allowed to access the financial Dropbox directory.
User behavior should be treated as a trajectory map. From the usual location of user operations, to the specific time they are usually active, and the typical services they visit, these are their activity tracks. After mapping their digital footprints on the user's virtual map, any of their anomalies should alert the system and act in accordance with a pre-assigned security policy. Unusual anomalous behavior is strongly signaled. For example, the geographic environment of the monitoring device can indicate that the user is attempting to log in from Asia while his device is in New York. Or, users who typically download 2MB to 3MB files per working day suddenly try to download 3GB files at 3am.
As for the collaboration model, any content that can be shared with collaborators should be monitored. This includes which permissions are granted, which users are active, which users can access which information, and can share this information as needed. Only systems that understand user behavior can mark users as believable and warn users to perform activities that may be at risk.
Device protection, network security, and user behavior are three elements of security, each of which is an integral part of ensuring cloud security. They are part of the security chain that includes the server itself, but they are equally important. Combining these three little-known factors with other key parts of the security chain will create more powerful cloud security. And chief information security officials don't have to worry about cloud security because they use the right cloud security approach.
