How to Protect Your Data When Sending Files
Protecting your data has become more critical than ever owing to the increasing number of cyber-attacks occurring in the technological realm. A study by the University of Maryland showed that on average, hackers attack every 39 seconds. Curbing this intrusion requires optimal security measures, especially when transferring your files or data. Ensuring that only the intended recipient can access the sent data is paramount. In this article, we will unravel practical ways to fortify your data while sending files, maintaining confidentiality, and ensuring the highest level of security.
**Choosing the Right Channel**
A secure transmission channel is a prerequisite to sending a secure file. Using a network connection that is unsecured might expose your data to potential hackers, who could intercept the files. You should always opt for a secured network connection for sending sensitive documents. Encrypted email services, messaging apps with end-to-end encryption, or secure file transfer protocols (SFTPs) are ideal choices for transmitting sensitive data securely.
**Encrypting the File**
Encryption is one of the most effective ways to safeguard your data. When you encrypt your file, you are obscuring the data making it unreadable to individuals who do not possess the decryption key. Even if the file is intercepted, it remains undecipherable to unauthorized persons. Advanced software like WinZIP or WinRAR allows data owners to compress and encrypt the data before transferring it.
**Password Protection**
Implementing password protection for your files is another practical measure to protect your data when sending files. This adds an extra layer of security ensuring that even if someone manages to access the file, they won’t be able to open it unless they have the correct password. You should ensure that the passwords you choose are strong—typically 8-12 characters, including alphanumeric characters, symbols, and are case-sensitive.
**Using Digital Signatures**
A digital signature is a technique that verifies the authenticity of digital messages or documents. It is an encrypted code attached to an electronically transmitted document to verify its contents and the sender's identity. This adds an extra layer of security and identification, making it difficult for hackers to tamper with your files.
**Using Secure File Transfer Tools**
There are specific tools designed to facilitate secure file transfer. For documents that require confidentiality, these tools are essential. They come with a suite of functionalities such as data encryption, password protection, digital signatures, and controls for who gets to see your files.
One of these is HelpRange, an online tool designed to offer robust PDF/document protection. Apart from offering high-end security, HelpRange also provides usage analytics, revealing who accessed your files, when, and for how long. With this, you can gain insights into your document's distribution and usage while ensuring its security.
**Deleting After Sending**
Once you are done sending your sensitive files, it's advisable to delete them from the device you sent from. This minimizes the chances of unauthorized access in the case of device theft or loss. If you need to keep a copy, make sure it's encrypted and stored in a secure storage solution.
**Educate Your Recipients**
Having taken all the measures to ensure the safety of your files, educating your recipients on how to maintain the security of the files is equally essential. Subjecting confidential documents to unprotected networks or computing devices is equally threatening and may compromise the data. As such, they should be informed about measures to ensure the documents' security, such as downloading over secure networks or storing them securely.
**Strengthen Your Firewall**
Firewalls serve to bar unverified access to your computer. This includes both outbound and inbound traffic. Strengthen your firewall security by employing techniques such as packet filtering, proxy service, or inspection services to filter out potential security threats that could compromise your data when conducting a file transfer.
In conclusion, data security is a crucial aspect in this age of digital transactions. Ensuring security when sending files guarantees the integrity of such files. By adopting measures such as data encryption, using secure file transfer tools like HelpRange, educating receivers, amplifying your firewall, and others, you rest assured that your data is prepared for any threats during transmission. Proactively investing in data security will not only defend your documents from unauthorized access but will also promote trust and loyalty from your stakeholders.
