Cloud security has been a hot topic for years. As the cloud computing market continues to grow, so does the need for companies to protect their data and applications.
Cloud security is more than just locking down information; it also means ensuring that all of your applications are as secure and compliant as possible.
For example, you might want to consider encrypting sensitive data before uploading it to a third-party service — even if that means paying extra money for encryption tools.
To answer all your queries, we have summed up the 5 most important elements of cloud security.
1. Centralized Logging & Secure APIs
The first component of cloud security is centralized logging. This is where all the logs from your applications, infrastructure, and even users can be collected and analyzed as a single source. Logs are essential to any good security program because they allow you to identify and diagnose problems with your system.
For example, if an application starts crashing more frequently than usual, it may be due to an error in the code or someone misusing it. These issues can only be identified by analyzing the logs generated by that application’s use over time – something that would not be possible unless you had centralized logging enabled on your system!
APIs are the new frontier of security. To keep up with the times, you need to understand what an API is and know how it can help your organization.
Encryption is the process of encoding data in such a way that only authorized parties can read it. There are many different types of encryption, but all involve using an algorithm to transform the original data into something unreadable by anyone who doesn’t have access to the password or key needed to make sense of the information.
It’s important for cloud providers to use strong encryption algorithms because if they don’t, it would be easy for someone with access to their servers (like hackers) to view sensitive information like credit card numbers or social security numbers.
3. Authentication and Authorization
Authentication and authorization are two key cloud security concepts.
Authentication is the process by which you can prove that you are who you say you are. It’s a way to verify that your identity information matches what is on file for your account or what has been previously entered into a system.
On the other hand, authorization determines what resources an authenticated user can access (and in what capacity). For example, suppose someone logs into a website using their email address as their username and password. In that case, they will be authenticated at a network level—but they might not have any permissions associated with that specific website yet. Their ability to read content could be enabled by adding them as an administrator of the site.
However, if there was no need for this particular user to have access to sensitive data within this organization, only general administrative functions such as managing permissions across all sites hosted on that platform. Then there would be no reason why they should need elevated privileges beyond those already given once logged in through authentication alone.
Additionally, in a cloud environment, it’s important to have logging and alerting in place so you can identify any potential security breaches early on. With real-time alerts, you can quickly respond by deploying remediation strategies such as freezing activity or shutting down applications.
It’s vital to know what is happening in your cloud environment so that you can detect and prevent any unwanted activities.
4. Data Lifecycle Management
Data Lifecycle Management tools are a set of features that help you manage data throughout its lifecycle. This includes tools like:
- Data Discovery, which allows you to find and classify all your corporate data so that it can be appropriately protected and managed;
- Data Classification, which is used to identify the sensitivity of each piece of information so that it can be appropriately protected or destroyed;
- Data Protection and Archiving, which provides encryption for sensitive information and an archival copy in case something happens to the original copy;
- Retention policies (which tell you how long information can be kept) as well as disposal policies (which tell you when sensitive data must be destroyed).
5. Contingency planning, Disaster Recovery, Backup and Restore
Contingency planning ensures that the system will continue to operate despite an outage of one or more components. The most common way to achieve recovery is using redundant hardware components in the same data center. This technique is called hot standby redundancy (or N+1 redundancy).
For example, suppose you have three web servers running in a physical server room. In that case, there should be four power supplies feeding those servers — one for each machine and one spare power supply for use when a maintenance operation requires shutting down a web server for maintenance work. In this case, all four machines are connected to redundant power systems so that if one fails due to an accident or malfunction, another can seamlessly take over its role without any loss of service to clients.
The most important thing about N+1 redundancy is that it needs only two essential (non-redundant) elements:
- An active device doing useful work at all times;
- A passive device ready to go as soon as needed; this last item must be located close enough to prevent too long delays before switching over from one device
Cloud security is protecting data and applications in the cloud from unauthorized access and use. It is a combination of people, processes, and technology that work together to ensure that information remains secure.
Cloud security requires us to understand what makes up the cloud infrastructure we’re working with. We need to know where each component lives (i.e., on-premises or in the cloud), what it does for us (i.e., compute power), who owns it (i.e., our own internal IT team or a third party provider), how it gets deployed (manually or automatically) and when an update will occur (on schedule or whenever possible).
The five elements of cloud security will help you build a more secure cloud environment by addressing all areas, from data encryption to access management.
