Why invite / create problems on purpose? It’s not hard to imagine there are those who benefit from people throwing money at their problems.īut even if it’s not planned, insecure computing and networking are where we came from. http: on general principles but it comes at a price, however intangible.Īnd lo and behold right when content delivery networks could use more capacity, now servers are becoming less efficient than ever, with their mitigations for newly “discovered” vulnerabilities going in. Many folks have more computer power than they need, and they might prefer an https: connection vs. We’re all becoming numb to mega/giga/tera but it’s an unprecedented large network and server load – by a lot. Let’s not forget, with concepts like “cumulative” and “6 month major release cycles” dawning, updates are working out to hundreds of megabytes to gigabytes apiece. That translates to money when running a network that’s tasked with delivering an unprecedented amount of data.

But then explain, why they offer kb articles via https, while downloads from http download links are redirected to https pages – and Update Catalog downloads still shipped via http.Ī reason might be that it takes computer power to encrypt large blocks of data. Well, we can discuss about http versus https. So: Overall I guess, it’s a ‘non optimal’ solution, Microsoft decides to use (nicely spoken). Brian below indicates, that some parts are checked and others not. I guess (haven’t tested it), the digitale signatur proof check will be executed for.

But Windows accept this update and install it. The saved package is flagged ‘as modified’ on digital signature property page. Then he used Notepad++ to edit some strings within the update package. He downloaded an update package via Microsoft Update Catalog. Within my German blog post, a reader did a simple test. Tested: Windows accepts altered updates … Since all Microsoft updates are signed, they are tamper-proof and thus secure regardless of whether the transport is secure. Please convert to plain text (.txt) before cut/paste If the update has been tampered with, it is not installed.”

When an update is downloaded, WSUS checks the digital signature and hash. In addition to signing each update, a hash is computed and sent with the metadata for each update. Microsoft mitigates the risk of sending update files over an unencrypted channel by signing each update. This is also the way Microsoft Update distributes updates.Īs discussed earlier in this guide, updates consist of two parts: metadata that describes what an update is useful for, and the files to install the update on a computer.

Note that WSUS only uses SSL for metadata. “WSUS also uses SSL to encrypt metadata passed between clients and downstream WSUS servers. WSUS also requires both HTTP and HTTPS ports, this is well documented: What additional benefit would using HTTPS offer? Absolutely nothing, it would just waste CPU performance.

Agreed, and also with the click bait comment above.
