Cloud Security refers to the practice of safeguarding cloud computing data, applications, and information from unauthorized access, malware, DDOS (distributed denial of service) and several other risks.
Global interest in cloud computing has shown significant growth in the last few years as more companies and enterprises are moving their data and application to the cloud.
Cloud has its benefits including improved flexibility, scaling, productivity, agility and profitability but every technology has its flaw. In cloud security, the flip side lies with breaches, information leaks, lack of control, data hacks and others which can be a nightmare for any organization or individual.
With more data and information moving to the cloud it is essential to maintain the sanctity and integrity of it. Many security professionals are still skeptical of cloud-based services infrastructure. According to a report, 24% of the enterprises have hosts missing high-security patches in the cloud environment. Well, due to these reasons, the cloud computing technology is throwing numerous opportunities for beginners and professionals in security, networking, architecture, etc., To grab this, you can go through AWS Technical Essential Online Course, blogs, videos, online platforms etc., where you will get to explore all the phases involved in the cloud computing development to deployement works.
Here are the some best practices which will help you to leverage the benefits of cloud by strengthening your defense against its issues and weakness:
1. Map your Cloud Processes
Although moving your data to the cloud is a positive and long-term decision, however, it can complicate your security policies in many unexpected ways. Hence, it is advised to map out your cloud processes and track them as soon as you make any changes.You need to remember a few points such as:
- Where your information is getting stored?
- What are the applied security rules to your folders and database?
- Who is allowed to access your database?
Once you map out the whole process, share it with your coworkers, trading partners, third-party vendors and people who have access to your cloud environment.
It is also advised to hire professionals who have security certifications such as CCNP Cloud certification, Azure Architect Certification, and others as organizations today, keep a close eye on certified professionals and data experts.
- Review Users Permission
Most of the cloud computing platforms have their security practices to protect the data of their clients, but still, it is recommended to practice best security hygiene from your side.
You can start with an audit of the user accounts and their cloud privileges. For example, if your employee has recently left your organization, then you must delete their accounts and remove their rights to access to the cloud.
This process also implies to the active accounts. You need to give the cloud users only that permission which is required to do their job.
If any user has more authority than they need then consider revoking it immediately to avoid any unnecessary risks.
3. Encrypt your data end to end
Whenever you transfer any data from the local network to the cloud environment always ensure the highest level of standard encryption methods such as SFTP, AS2, FTPS, and SCP.
Practice the given methods even if your data is at rest at the cloud server. The level of encryption for your files, folders or database is up to you, but it is recommended to use the maximum level of security you can provide to your cloud server.
Many organizations like to use the latest and up-to-date standards and guidelines for a secure cloud file transfer solutions.
The encryption keys used should also encrypt themselves regularly with a rotated set of master keys.
Get a Cloud Disaster Recovery Plan
The best way to keep your data secure is to plan for the future and prepare for the worst. To do so try to get the best cloud disaster recovery plan.
With the help of the disaster recovery plan, you can schedule automated backups and save multiple copies of your cloud environment to several non-local geographical locations.
All the cloud computing platforms provide their recovery tool to create backups frequently.
You can save your database in two more data centers- for example, one in London and the other in California. By following this method, you can be sure that your data is secure even in a possible natural disaster.
5. Frequent Vulnerability testing
Use the best and industry-leading vulnerability testing and incident response tools. These tools are fully automated, and they test system issues and weaknesses and fix them accordingly.
These applications and tools save a lot of time and manual labor for critical security audits from yearly to monthly or even daily.
It’s up to you do decide when a vulnerability assessment is required, varying from network to network. You can even schedule in the evaluation or make the tools perform on demand.
6. Log Management and Monitoring
Log management and its reviews are essential security practice when remote management systems or cloud servers are concerned.
Most organization leverage their access on logs and monitor any unexpected behavior and keep track of their users who have access.
Continuously monitoring logs are helpful to pick a pattern on unsafe behavior and malicious activity which assist in a further investigation.
Unified log management can help in threat detection by real-time tracking which will help you to know where things went wrong and what necessary steps you need to make it right.
7. Stay Informed
You need to stay updated about the latest threats and emerging vulnerabilities that may affect your enterprise or organization.
The importance of security research and gathering valuable information for your organization’s security cannot be understated.
To act with confidence, you need to know the details and working of the system as well as the potential impact of any new vulnerability.
Cyber-ignorance is one of the most dangerous traditions of many industries which can affect their growth and scalability. Thus, it is advised to keep everyone informed about the latest technologies used in cloud security.
Cloud security is not just a platform debate; it’s more about understanding the organization’s requirement and thereby the most efficient way to secure applications and database on the cloud environment.
Security is the primary component at the beginning of any new project so that when you spin up new tools and systems, it does not impact the overall process.
If you have a company and planning to move your database to the cloud, securing your on-premise servers should be your primary focus. Later you need to follow the necessary steps and methods to protect data in the cloud.
Follow the above practices to make informed decisions regarding cloud infrastructure and its security.
