SECURE FILE SHARING – ISMS TIPS – WEEK IV
Secure file sharing is the process of transferring files online in a way that protects them from unauthorized access, modification, or disclosure. Secure file sharing is important for complying with the information security management system (ISMS) standards, such as ISO 27001, which aim to ensure the confidentiality, integrity, and availability of information.
There are different ways to share files securely online, depending on the type, size, and sensitivity of the files, as well as the preferences and needs of the sender and the receiver. Some common methods are:
- Cloud storage services: These are online platforms that allow users to store and share files over the internet. Cloud storage services offer secure file sharing and protection with various security features, such as permission-based access, password protection, encryption, virus scanning, ransomware detection, and more. Some examples of cloud storage services are Dropbox, Google Drive, OneDrive, and Internxt.
- Email attachments: These are files that are attached to an email message and sent to one or more recipients. Email attachments are convenient for sharing small files, but they have some limitations and risks. For example, email attachments may have size limits, may be blocked by spam filters, may be intercepted by hackers, or may contain malware. Therefore, email attachments should be encrypted and scanned before sending or opening them.
- File transfer services: These are online tools that allow users to upload and download files from a server. File transfer services are useful for sharing large files that cannot be sent via email or cloud storage. However, file transfer services may also have some drawbacks, such as limited storage time, bandwidth restrictions, or lack of security features. Therefore, file transfer services should be chosen carefully and used with caution. Some examples of file transfer services are WeTransfer, MediaFire, and SecureDocs.
- Virtual private networks (VPNs): These are secure connections that create a private network over a public network. VPNs allow users to access and share files securely from any location, as if they were on the same local network. VPNs encrypt the data that is transmitted over the internet, making it unreadable to anyone who intercepts it. VPNs also hide the user’s IP address and location, enhancing their privacy and anonymity. Some examples of VPNs are ExpressVPN, NordVPN, and CyberGhost.
To choose the best way to share files securely online, you should consider the following factors:
- The size and type of the files you want to share
- The number and identity of the recipients you want to share with
- The level of security and privacy you need for your files
- The speed and reliability of your internet connection
- The cost and convenience of the service you want to use
