iPhone takes security to the next level
iPhone takes security to the next level

Apple's most powerful iPhone security setting ever, Lockdown Mode, is an unexpected addition to iOS 16.

The new security model, which will also appear in macOS Ventura and iPadOS 16, is not for everyone. In fact, you might argue it's for a select few: those who believe they could be targeted by state-sponsored cybersecurity attacks. In other words, this is software for the President of the United States. It might also be for the head of your local power authority, water treatment plant, or a journalist covering the war in Ukraine. And thanks to Apple, anyone with an iPhone, it seems.

Lockdown Mode is Apple's new hardcore approach to security that, when enabled on an iPhone, will introduce five key protections, any one of which might make your iPhone less useful and fun, but also, apparently, a whole lot more secure.

These protections include.

Most message attachment types other than images are blocked and link previews are disabled.
In Safari, some web technologies, including just-in-time (JIT) JavaScript compilation, are disabled. Though you can exclude a trusted site from Lockdown mode.
It disables or blocks some Apple services like requests for incoming FaceTime calls from unknown callers (ones where you haven't previously initiated a Facetime call).
Wired connections with a computer or accessory are blocked when iPhone is locked.
You can't install configuration profiles and won't be able to enroll the device in mobile device management (MDM) when Lockdown Mode is enabled.
Together, all of these could significantly reduce attack avenues on your iPhone, and on your iPad and Mac, if you enable it on those systems, too.

In a release on Lockdown Mode, Apple says adding all three platforms to the security matrix "further hardens device defenses and strictly limits certain functionalities, sharply reducing the attack surface that potentially could be exploited by highly targeted mercenary spyware."

While this level of restricted access would feel like overkill for the average consumer or business person, many folks will find this Lockdown Mode useful, including those whose phones are connected to a variety of apps, services, and contracts relating to government, law enforcement, infrastructure, human rights groups, and news reporting.

For those working on the front line of human rights, Lockdown Mode might be a low-cost and efficient way of protecting their phones. It might also be a little too restrictive; there's a chance that it might be more effective in an official capacity.

Back in the day,  government officials, including the US President, were handed specialized and highly-secure phones, though some reportedly kept using their personal iPhones(opens in new tab). iOS 16 Lockdown Mode, which is already appearing in Developer Beta 3, might be a way of giving officials their iPhone cake, while eating securely, too.

My Take: Good for you, Apple. Thanks for keeping us safe.

We reached out to Rich and his team at Computer Geek in July 2021. We were in desperate need of help because our former website design agency left us hanging with major website issues that needed immediate attention. Rich and his team were extremely helpful and quick to come to our rescue! They have helped us with numerous projects that have helped our SEO. Our sales have increased 30% since coming to Computer Geek. We've been working with them for about nine months now and are very pleased with their response time and helpful manner. Rich has proven himself to be trustworthy and dependable. We feel valued as a customer and look forward to continuing a relationship with Computer Geek.

I would certainly like to recommend that anyone pursing maintenance for a website to contact The Computer Geek. I have been using another company to do some maintenance on my site with moderate success. There were issues that were evidently beyond what could be handled by them. However, the professionals at The Computer Geek had them addressed and rectified in no time at all. The Computer Geek approached all of my requests focusing on my goals and the needed performance. Then, once versed, presented me with a very reasonable price. Once the projects were in motion, I found that the tasks were achieved before I expected, with professional results. Also, in one instance where The Computer Geeks brought an issue to my attention that I would have likely overlooked. This was accompanied by a recommendation on how to solve the issue. Overall The Computer Geeks exceeded my expectations!

We discovered an issue with our Oscommerce cart processing images. It is about 14 years old and heavily modified. Looking on google for some expert help I found Rich and reached out to him. We received a response the same day. The next day his team was working on our issue and was able to solve it within a few hours. Price was reasonable and we are very appreciative to find a competent and professional oscommerce expert to help successfully troubleshoot our issue.

I'm very new to the whole idea of having a website / blog. I used Bluehost.com and WordPress.org to create Thepredatorhunter.com and then managed to wreck it.

In trouble? Stop fretting and start typing in the chat box. You will be glad you did!
