Rules can be per Security Group, too, for fine-grained access control. I would also strongly recommend that installation of dependencies is a build-time task, not a run-time task, and if those two stages are separated, it makes egress filtering a whole lot more effective since the build-time allowlists are often multi-tenant CDNs where a threat actor can host their own data capturing or malicious payload delivering service.
• Google's CRLs from the same intermediate CA (same public key) have different URLs and different content when pulled from different hosts (google.com, youtube.com).
• DigiCert has sharded according to 'assurance' class, algorithm, year and acquisition's name.
• Sectigo also has sharded according to 'assurance' class [1].
• GlobalSign has sharded by the yearly quarter presumably.
• HTTP Cache-Control maxage (or s-maxage), 'Expires' and 'Next Update' within the CRL file are not in sync.
• Some CAs other than Let's Encrypt also do not publish CRL URLs in the leaf certificates.

Data is on CRL availability, number of entries, expiry & refresh times, etc. from various x509 leaf server SSL certificates.

It can be disabled if an organisation wishes to. I wrote about how to do this in Chrome [2,3], and will write about Firefox when I get a chance.

*for many websites, the domain name visibility during an HTTPS handshake will no longer be available to firewalls/proxies (unless they were terminating.)
10. What are the usage limitations for HashiCorp’s products under BSL?
All non-production uses are permitted. All production uses are allowed other than hosting or embedding the software in an offering competitive with HashiCorp commercial products, hosted or self-managed.
24. Can I host the HashiCorp products as a service internal to my organization?
Yes. The terms of the BSL allow for all non-production and production usage, except for providing competitive offerings to third parties that embed or host our software. Hosting the products for your internal use of your organization is permitted.
[1] https://www.hashicorp.com/license-faq Removed Message Lookups. This is a hardening related to changes made to prevent CVE-2021-44228. While this change is recommended, it is NOT required to fix CVE-2021-44228.
[1] https://lists.apache.org/thread/d6v4r6nosxysyq9rvnr779336yf0...> This article will examine the unnamed and potentially devastating constraining effect of software on human autonomy. I call this concept residual causality, where software design decisions made long ago in different circumstances for different reasons constrain human action in an unknown future. The less aware the designers of software systems are of complexity in social systems, the more likely they are to introduce residual causality."
1. TLS inspection: Azure Firewall Premium terminates outbound and east-west transport layer security (TLS) connections. Inbound TLS inspection is supported in conjunction with Azure Application Gateway allowing end-to-end encryption. Azure Firewall performs the required value-added security functions and re-encrypts the traffic which is sent to the original destination.
2. IDPS: Azure Firewall Premium provides signature-based intrusion detection and prevention system (IDPS) to allow rapid detection of attacks by looking for specific patterns, such as byte sequences in network traffic or known malicious instruction sequences used by malware.
3. Web categories: Allows administrators to filter outbound user access to the internet based on categories (for example, social networking, search engines, gambling, and so on), reducing the time spent on managing individual fully qualified domain names (FQDNs) and URLs. This capability is also available for Azure Firewall Standard based on FQDNs only.
4. URL filtering: Allow administrators to filter outbound access to specific URLs, not just FQDNs. This capability works for both plain text and encrypted traffic if TLS inspection is enabled.
