UAG Certificate Validation


Sometime it may be desirable to disable certificate validation for the SSL protected back-end services published via UAG. You can do this by editing the following registry keys:
  • Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\WhaleCom\e-Gap\Von\URLFilter\Comm\SSL
    • right-click ValidateRwsCert, select Modify, and change the Value data to 0
    • right-click ValidateRwsCertCRL, select Modify, and change the Value data to 0
    • restart IIS
Please, note that disabling certificate validation process may not be an acceptable security practice in certain environments. For a complete list of UAG registry keys consult the following TechNet article. Also, there are different uses for certificates within UAG, to understand them better I strongly recommend reading through the following excellent blog post by Ben Ari.

Updating computer's AD Security Group membership without rebooting

I found the following to be very useful - From the elevated command prompt execute “ klist –li 0x3e7 ” to view the logon session of the computer account . To purge them, simply execute “ klist –li 0x3e7 purge ”. A typical use case might involve targeting GPOs based on computer's group membership. When you add computer to the group in order to test the application of policies you can reboot it or, alternatively, run the above mentioned to clear logon sessions, then do “ gpupdate /force ” and check. In a spirit of giving credit where credit is due, I found a few references to this, but the one I learned it from was  http://setspn.blogspot.com/2010/10/updating-servers-security-group.html

WordPress displays weird characters

Sometimes after a database conversion (e.g. from MySQL to MariaDB) or due to encoding issues a situation might arise when WordPress is showing weird characters. A quick way of remedying the situation would involve examining the pages to discover a pattern (what characters are being substituted, in the example below the apostrophe was replaced by  ’ ) then running an queries against the database to reverse the effect. Here's a quick example (common tables that store content): UPDATE  wp_posts  SET  post_content =  REPLACE (post_content,  'Â' ,  '' )      UPDATE  wp_posts  SET  post_content =  REPLACE (post_content,  '’' ,  "'" )      UPDATE  wp_postmeta  SET  meta_value =  REPLACE (meta_value,  'Â' ,  '' )      UPDATE  wp_postmeta  SET  meta_value =  REPLACE (me...

  AI Agents as Trusted IoT/Software Defined Devices 🤖 Your Newest Endpoint Isn’t a Laptop; It’s an AI Agent. Are You Ready to Secure It? Dive into the next frontier of cybersecurity. Autonomous AI agents are no longer just code; they are powerful actors in our digital ecosystems. Treating them as simple software leaves a massive security gap. Our latest report introduces a new paradigm: The AI Agent as a Software-Defined Device. Discover the essential framework for securing the agentic future: ➡️ The Agent-as-Device Model: Learn why abstracting agents as software-defined devices, similar to IoT endpoints, is the key to managing their complexity and risk. Secure the “hardware” (host), “software” (agent logic), and “network” (communications). ➡️ A Digital Passport for AI: Move beyond static API keys. Explore how Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) create a cryptographic root of trust, giving every agent a verifiable identity and provable permissions. ➡️...
