Looking at encryption vs decryption, they might sound similar, but they come with pretty different focus areas. The short version is that encryption makes sure that only authorized users can read the data. Whereas with decryption, you\u2019re getting a restoration of data to its original and usable form.<\/span><\/p><p><span style=\"font-weight: 400;\">You\u2019ve likely heard both of these words before, but context definitely matters when it comes to network security and all of the associated hardware. As a whole, the fundamentals behind these words support data confidentiality, integrity, and authenticity through efforts like digital signatures.<\/span><\/p><p><span style=\"font-weight: 400;\">It can get a lot more complex than this, but it doesn\u2019t have to turn into a headache just to benefit from what they bring to your network security strategy. This article provides a clear look into encryption vs decryption to help you avoid any confusion when it comes to your <\/span><a href=\"https:\/\/www.firewalls.com\/blog\/network-security-tools\/\"><span style=\"font-weight: 400;\">network security setup<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f5240a0 elementor-widget elementor-widget-heading\" data-id=\"f5240a0\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h1 class=\"elementor-heading-title elementor-size-default\">Encrypted vs Decrypted Data\n<\/h1>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f3d89c0 elementor-widget elementor-widget-text-editor\" data-id=\"f3d89c0\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">Diving a little deeper into the topic, encrypted data changes from plaintext to unreadable ciphertext. This works to protect sensitive data points from unauthorized access. Decrypted data restores data to its original format, while still guaranteeing that only authorized access is allowed. They work in opposite directions, with both minimizing vulnerabilities along the way.<\/span><\/p><p><span style=\"font-weight: 400;\">A few real-world use cases you\u2019re likely used to encountering include end-to-end encrypted messaging, secure web browsing, and email security. From the business world to our everyday lives, you can easily find encryption and decryption at play. At the same time, it\u2019s pretty important to understand how they handle data and what makes them different for the sake of your company\u2019s network security.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-476c78e elementor-widget elementor-widget-heading\" data-id=\"476c78e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">What is Encryption?\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ebdef0c elementor-widget elementor-widget-text-editor\" data-id=\"ebdef0c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">In today\u2019s world, encryption is seen as a pretty base-level security solution, but many people don\u2019t truly understand how it works. It\u2019s a core component of safeguarding your data while maintaining its integrity through authenticity verification. While protecting your business from data breaches requires a multi-layered strategy, encryption is definitely a part of that.<\/span><\/p><p><span style=\"font-weight: 400;\">Here are a few unique elements about encryption that make it so important for your network security:<\/span><\/p><ul><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Protects all of your most sensitive internal business data, from financial records to intellectual property, and more<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reduces the risk of cyber threats during the transmission or storage of critical data points<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Helps you maintain compliance with security regulations like GDPR, HIPAA, and more<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Prevents unauthorized tampering with important data, maintaining accuracy and integrity<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Acts as a measure of reassurance to clients and customers interacting with your business<\/span><\/li><\/ul><p><span style=\"font-weight: 400;\">Encrypted file sharing for business use cases is easy to understand, but there are times when decryption is needed as well.

By turning data back into readable plaintext, it can be reviewed, but only by authorized users. That doesn\u2019t mean you can overlook security measures, but there shouldn\u2019t be any irrational fear behind using decryption when it\u2019s needed most.<\/span><\/p><p><span style=\"font-weight: 400;\">In comparison, the list below offers a quick gist of how decryption works from several angles:<\/span><\/p><ul><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Decryption works to restore scrambled data for ease of access and usability<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Keys, in this context, are used to unlock data points<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It provides access to data, but only for authorized users<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Decryption-specific algorithms decode the information rather than turning it into ciphertext<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Works to enforce access control, but doesn\u2019t compromise your network security<\/span><\/li><\/ul><p><span style=\"font-weight: 400;\">Don\u2019t let the similar terminology fool you here, as both of these security practices go hand in hand.
