Should we be sharing files via email?
Reducing cyber breach risks in your business
Sending information by email is never really secure, even over an HTTPS connection. Not all email providers offer an encrypted way to send messages.
Unless the files themselves are encrypted, such as by using a password-protected PDF, there is no guarantee that the intended recipient will be the only one to see the message.
Email attachments vs share links:
|Email attachments: 👎||Share links: 👍|
|👎 Limited to about 10mb||👍 Can handle 1gb or more|
|👎 No security features||👍 Can be password protected|
|👎 Spam filters can block genuine attachments||👍 Links aren’t caught by spam filters|
|👎 Can take up precious storage space||👍 Stored on the cloud, so no storage space needed|
|👎 Don’t know who else accessed it||👍 Track all opens and downloads|
|👎 Attachments never expire||👍 Expiration or destruction dates can be set|
|👎 Mistakes can’t be corrected without re-sending||👍 The information can be updated at any time|
|👎 Can’t be recalled if sent in error||👍 Link access can easily be revoked|
Sharing files using a removable device
Sharing files by using a removable storage device like a USB stick or flash drive can be a bit more secure than email. It involves directly copying or moving the files onto the removable storage device and then physically transmitting it to the recipient.
However, USB storage devices are small and can easily get lost or stolen. Therefore extra care must be taken when sharing sensitive files via removable device.
Do’s and don’ts for devices
❌ plug an unknown flash drive into your computer
❌ use the same flash drive for work and personal files
❌ purchase a flash drive from a non-reputable seller
✔️ use a password-protected or encrypted flash drive
✔️ keep it in a safe and secure location
✔️ report a lost or stolen flash drive
File sharing by printing
If you are printing information to physically hand or send to someone, be aware that it comes with cyber security risks.
Possible risks include:
- Data being sent to a printer over an unsecured network
- The printer storing data on an unencrypted hard drive during the printing process
- Sensitive data being sent to the wrong printer
- The documents ending up in the wrong hands
- Printers themselves can be vulnerable to hacking
It’s not just cyber security to be aware of when printing. Not being cautious when using printers can also result in data protection breaches. Leaving personal information for others to find it, not properly shredding used data, and even not using the latest secure printing technologies could result in a GDPR breach. This is because data protection law requires all proper technical measures to be taken to protect personal information.
