Tails

 

Introduction

Tails, the Linux distribution known for providing anonymous and secure internet browsing, has recently released its latest version, Tails 5.14. This update brings several enhancements to the persistent storage, stronger encryption, and updated software. In this article, we will explore the key features of Tails 5.14 and how it further enhances the privacy and security of its users.

Stronger Encryption for Persistent Storage

One of the notable improvements in Tails 5.14 is the upgrade of the persistent storage’s cryptographic parameters. Previous versions, including Tails 5.12, experienced vulnerabilities when faced with physical attacks from state-level adversaries. To address this, Tails 5.14 converts the persistent storage to LUKS2 encryption with Argon2id. However, Tails’ maintainers recommend users to update the passphrases of their LUKS-encrypted drives, especially if they are not already composed of five or more random words^1.

Simplified Backup Process

Tails 5.14 introduces a simplified backup feature that allows users to create a backup of their persistent storage directly from the installer. This new functionality clones the storage entirely onto a backup Tails system. Of course, users can still utilize the existing backup tool, which enables backup updates and offers faster performance^1.

Improved Captive Portal Detection

For users who need to authenticate their internet access through captive portals, Tails 5.14 now supports the detection of these portals even when the option for automatic connection to the Tor network is enabled. The error message appears promptly and advises users to first sign in to the network before proceeding^1.

Tor Browser Update

With Tails 5.14, the Tor Browser is updated to version 12.0.7. The developers have made some notable changes, such as transforming the button for creating a persistent storage into a slider on the welcome screen. Additionally, they have added descriptions for various features of the persistent storage. Tails now hides duplicate entries for persistent bookmarks in the Files file browser. Furthermore, the desktop environment no longer restarts when users create a persistent storage^1.

How to Update Tails?

Updating Tails to the latest version is a straightforward process. Users can utilize the automatic update function directly on their USB stick. It is highly recommended to perform updates, especially when persistent storage is in use, as reinstalling Tails may result in the loss of stored data. Visit the Tails website to find USB stick images and ISO images for download^1.

Conclusion

Tails 5.14 brings significant improvements to the popular Linux distribution, enhancing the security and privacy features that users rely on for anonymous browsing. With stronger encryption for persistent storage, simplified backup functionality, improved captive portal detection, and the latest version of the Tor Browser, Tails 5.14 ensures a safer online experience for its users. Stay updated with the latest version of Tails to benefit from its ongoing commitment to privacy and security.

 

Understanding MITRE ATT&CK®: A Comprehensive Guide to Effective Cybersecurity

MITRE ATT&CK®

Introduction

In today’s interconnected world, the threat landscape for cybersecurity is constantly evolving.
