Cloud storage security: how to make your cloud storage safer

Cloud storage allows storing files and information online without worrying about device capacity. Both individuals and companies face daily risks of hacking and data disclosure, therefore, protecting your cloud storage accounts is extremely important. We describe key actionable steps to enhance cloud storage security to safeguard your data.

We store more and more of our lives online and with cloud storage becoming a go-to solution for storing everything from personal memories to sensitive business documents, ensuring its security is non-negotiable. That's where Koofr comes in. As a trusted, European cloud storage provider that stands out for its commitment to security and privacy, Koofr offers a secure platform with security features to keep your data safe from threats.

If you find yourself wondering, "How can I make my cloud storage more secure?" – here's the answer. In the next paragraphs, we'll explore how to enhance your cloud storage security using Koofr's tools and best practices. Whether you are storing personal photos or business documents, these tips will help you sleep easier knowing your data is protected and safe from prying eyes and cyber threats.

1. How can I make my cloud storage more secure: Understanding the threat to cloud storage security

Common threats to cloud storage security are data breaches in which access to sensitive data is gained due to vulnerabilities in the cloud storage security infrastructure or due to compromised credentials, unauthorized access through phishing attacks, weak passwords or credential theft, and malware and ransomware attacks. Data can also be intercepted during transmission between the user's device and the cloud server or can be vulnerable to unauthorized access due to a lack of data encryption both in transit and at rest.

All of these threats can lead to adverse consequences such as data exposure, data manipulation, and theft. Additionally, misconfigurations on the users' side like weak passwords and neglecting the option of two-factor authentication give rise to significant risks. These vulnerabilities on the side of the users can be as detrimental to cloud storage security as external threats, mentioned before.

Cloud storage services provide robust security measures to protect user data, along with options that empower users and offer them additional tools for extra protection. The combination of security features and best practices on the provider's and the user's side offers the necessary security measures to mitigate common threats to cloud storage effectively.

Therefore, proactive security measures from the users' side, including regular password updates, use of robust authentication methods and client-side encryption are essential for bolstering cloud storage security and cannot be neglected.

2. How can I make my cloud storage more secure: Strong passwords and multi-factor authentication

There are a few different ways of strengthening your cloud storage defences. One of them is using strong passwords. The significance of passwords in our data security strategy is often underestimated, yet they serve as the primary defence against all data threats.

You must dedicate time to selecting secure and unique passwords to protect your data. Utilizing helpful tricks and specific tools can help in choosing and managing passwords more efficiently. Password managers, for example, are of great help. They serve as valuable tools for generating strong, unique passwords for each online account, eliminating the necessity to memorize them all. They encrypt passwords and store them in a secure digital vault, protected by a master password or biometric authentication. Additionally, they offer convenient features like auto-fill and auto-log-in, simplifying access to online accounts while strengthening security by mitigating the risks associated with password reuse or weak passwords.

Often, using only passwords to secure your online accounts is not enough, no matter how strong they appear to be. A very important aspect of cloud storage security is multi-factor authentication (MFA). This feature adds an extra layer of protection to cloud storage accounts, safeguarding them against unauthorized access, even in cases where the password is compromised. Multi-factor authentication establishes a robust second line of defence by requiring secondary confirmation, such as a confirmation through an authentication app on your smartphone or your fingerprint, to grant access to your account.

Enabling two-factor or multi-factor authentication on your Koofr cloud storage account will double the security of your data following only a few simple steps.

3. How can I make my cloud storage more secure: Data encryption and its role in cloud storage security

Data encryption plays an important role in ensuring the security of cloud storage. It converts readable information into incomprehensible text or ciphertext using mathematical algorithms, ensuring data confidentiality by safeguarding it against unauthorized access. Encryption is fundamental for protecting sensitive data such as passwords, financial information or any kind of private information while it is stored, used or transferred, ensuring user privacy and security.

Koofr encrypts data at rest, which refers to information stored within its system, and data in transit, the information that is transferred between devices or servers. By encrypting data in both circumstances, Koofr ensures that sensitive information remains protected from unauthorized access or interception at all times. This comprehensive encryption strategy enhances overall security and guarantees compliance with privacy regulations. Moreover, with client-side encryption, Koofr Vault empowers users with enhanced control and protection over their data. Secure your cloud storage files through Koofr Vault, where your files are encrypted locally on your device.

For data encryption to be used effectively, users must grasp the encryption settings, responsibly manage the encryption keys, and adhere to best practices to optimize encryption's effectiveness in protecting their data.

4. How can I make my cloud storage more secure: Cloud storage security and access control permissions

If multiple users have access to cloud storage data, then controlling access is vital for safeguarding privacy, security, and compliance. By managing access permissions, you ensure that only authorized users can view, modify, or delete sensitive information, reducing the risk of data breaches and unauthorized access.

Defining roles, creating groups or user categories, specifying permissions, using strong authentication methods for accessing the cloud storage account, and monitoring the activity of your cloud storage account can prevent or detect threats in time.

Koofr offers the option to set access permissions when sharing folders with the Add people option. If you share your folder with that option, you can add different permissions for each member by clicking the Modify button next to each member and choosing the correct permissions from the list. You can define who can comment (and also see comments) or modify the shared files within the folder, who can create download and upload links, and who can manage share.

Monitoring your cloud storage account for suspicious activity allows you to take immediate action to protect your data. You can enable account alerts for login attempts, file access, and other activities to increase your security by providing real-time notifications of potentially suspicious behaviour.

5. How can I make my cloud storage more secure: Best practices that ensure cloud storage security

We’ve covered the key tools and methods to improve your cloud storage security but there are some other best practices that you should consider and use too.

Keep your software updated: Regularly update your operating systems, applications, and security software to patch vulnerabilities and protect your accounts and devices against emerging threats.

Be cautious about phishing: Stay alert against phishing attempts by carefully examining emails and messages for suspicious links or requests for sensitive information.

Avoid sharing access credentials: Never share your login credentials, passwords, or access keys with anyone and use secure methods for sharing access to cloud storage resources.
