Disable insecure connections

Overview​

About this category

This category contains privacy scripts for Windows.

These changes use Windows system commands to update your settings.

This category includes scripts designed to enhance users' security and privacy by disabling outdated or vulnerable connections across the system. It safeguards data against interception, unauthorized access, and attacks that exploit outdated technology vulnerabilities, including man-in-the-middle attacks and data breaches.

By disabling these insecure connections, these scripts follow cybersecurity best practices and recommendations. Although Windows supports insecure connections for compatibility, prioritizing security, these scripts disable them.

Caution

This may cause compatibility issues with older devices or software.

Caution: Mixed Risk Levels

Be careful running these scripts. This category includes scripts with high impact:

  • 🔴 Some not recommended scripts. They should only be used by advanced users. They may break important functionality.
  • 🟡 Some recommended scripts only if you understand its implications. Some non-critical or features may no longer function correctly after running this this category.
  • 🟢 Some safely recommended scripts. Safe-to use for any user.

Apply now​

These scripts are written using Batch (batchfile) scripting language.

Choose one of two ways to apply:

  1. Automatically via privacy.sexy: The easiest and safest option.
  2. Manually by downloading: Requires downloading a file.

Alternative 1. Apply with Privacy.sexy​

privacy.sexy is free and open-source application that lets securely apply this action easily.

Open privacy.sexy

It allows selectively choose parts of this action to conduct. You can fully restore this action (revert back to the original behavior) using the application. Additionally, you can apply only the recommended scripts, instead of applying all of the scripts.

Disable insecure ciphers

This category improves network security by disabling outdated and less secure cipher suites. Cipher suites are sets of cryptographic algorithms used to secure network connections. They include ciphers, known as bulk encryption algorithms or simply bulk ciphers. Ciphers encrypt messages exchanged between clients and servers. Using outdated cipher suites exposes data to risks of interception and tampering during transmission. Disabling insecure ciphers meets security standards set ...

Disable insecure hashes

This category includes scripts to disable insecure hash algorithms during cryptographic operations. Hash algorithms are essential for internet security, electronic banking, and document signing. Insecure hashes, however, are susceptible to collision attacks. This vulnerability enables attackers to spoof content, perform phishing, or execute man-in-the-middle attacks. Consequently, an attacker could intercept or modify data transmitted over what is believed to be a secure connection, without bein...

Disable insecure protocols

This category focuses on enhancing user privacy by disabling legacy and insecure communication protocols. It targets protocols that expose users to security vulnerabilities due to their outdated nature. Retaining obsolete protocols creates a false sense of security because they may seem secure but are vulnerable to exploitation. Authorities like NIST (FIPS), NSA (National Security Agency), Office of the Chief Information Security Officer, Microsoft, Mozilla, PCI Security Standards Council, the C...

Disable insecure renegotiation

This script enhances your security by reducing risks associated with secure communications. By running this script, you proactively enhance your online privacy and secure against well-known TLS vulnerabilities. TLS secures internet communications. It allows parties such as browsers and websites to update their encryption settings through renegotiation. Without safeguards, attackers could intercept and compromise these communications. Insecure renegotiation can let attackers hijack communicat...

Disable insecure connections from .NET apps

This script improves security by enforcing secure network connections across all .NET applications. By setting the "SchUseStrongCrypto" configuration, it prevents the use of outdated and insecure connections, including: Protocols weaker than TLS 1.1 and TLS 1.2. • Cipher algorithms such as RC4, NULL, DES, and export suites. • Hash algorithms like MD5. Authorities like Microsoft, and Department of Defense (DoD) recommend this configuration as part of their security guidelines. This script applies...
