Being on the law enforcement court-ordered side of the house for suspect device records and also physically processing iPhones through Cellebrite's UFED, I wanted to see what the difference was between user-requested data and court-ordered or forensically captured data. So, on 15 February 2019, I navigated on over to Apple's privacy page ( and requested a copy of my data. [ 421 more words ]

I recently updated my MX records to reflect changes to my mail host. If you are making MX changes and are using MTA-STS, don't forget to update your MTA-STS text record with valid MX servers and the MTA-STS serial number in your DNS TXT entry. My previous MTA-STS ID was id=20160831085700Z and taken directly from the IETF's draft MTA-STS page. If you remember correctly, any changes to your MTA-STS record require a change of the ID.

DNSviz, provided by Sandia National Laboratories, is a great tool in validating the chain of trust for DNSSEC. Check them out if you need DNSSEC validation or other insight in DNS troubleshooting. Back story: For any public-facing domains that I setup, I configure DNSSEC about 24 hours after the domain is purchased and configured in Cloudflare. From personal experience, if you enable DNSSEC too soon after registering a domain, you run the risk of resolution problems. [ 172 more words ]

"Be strong... to be weak is to invite aggression, oppression, tyranny, misery and woe." - Louis Karoniaktajeh A multi-part series by John Ball, Phillip Kuzma, and Ted Nass on server security. I'll be covering a few security topics centered around email in this post. The configuration of many of these technologies is vendor specific, meaning if you use Google Apps for Business then there is a Google-specific implementation and for Office 365 there is a Microsoft-specific implementation.

This is a follow up to: If you're using the "All In One WordPress Security & Firewall" plugin in conjunction with Cloudflare, there are a few tweaks you'll need to make to ensure proper compatibility. One of the biggest changes, which might not work unless you have server-side access to make changes, is to configure the server to allow real IP's to pass through as opposed to Cloudflare-obscured IPs.

So you've deployed SharkRF perhaps following this guide ( and now you need to update your deployment. Should be a straight forward process. I'm going to make an assumption we are on Ubuntu. If you're running your SharkRF server on a virtual machine, take a snapshot. In VMware ESXi, this is as simple as right-clicking on the virtual machine and selecting "take a snapshot".
