In this case, Apple took only 10 days to release its security patch. Apache must be enabled either through the Sharing preference pane's Web Sharing service check box or at the command line. Ruby isn't used for any native Apple products, and it must be wired in at the command line or through third-party packages.

Locking down this sort of access would prevent the most likely security flaws from being exposed, but that's problematic with the current OS. Configuration management software does exist to help such a lockdown, but again, Mac support may not exist in the software you're running companywide. That should change. Solution: Consider limited deployment of third-party software to restrict configuration by administrative users if your current solution doesn't include Mac support.
For home users and small businesses, the distinction is probably enough.
An unprivileged or normal user can be restricted via parental controls and typically can't create user accounts, enable file-sharing services, or install certain kinds of software. For that, an administrative-flagged account is needed.
Punching a Hole for Back to My Mac
But with administrator privilege set, a user can turn on features through switches in System Preferences, such as enabling Samba -- "the Mac version is typically three to six months out of date," Mogull says -- or using the Terminal application to activate any of the thousands of Unix daemons and servers that ship as part of a stock Mac OS X system. By contrast, a single click might be enough in Mac OS X.
Mac from Apple and administrator privileges.
While Apple uses IPv6 tunnels, IPsec encryption, and Kerberos tickets to secure connections, starting up such a connection from anywhere on the Internet requires just the password to someone's MobileMe account. With that password, all computers with Back to My Mac enabled can have their files examined or screens remotely controlled.
In a managed enterprise, security experts don't believe that Back to My Mac creates any real risk, despite its feature set. If users are running Back to My Mac on their own, "it would mean that [IT] royally screwed up" the firewall, he adds. Matasano Chargen's Ptacek says that Back to My Mac will eventually fall under the category of services that businesses ban their employees from using in the office.

Solution: Confirm that Back to My Mac won't work in your environment. Establish a policy that bans its use.
But that Trojan horse doesn't meet the smell test: Like a few other "concept attacks," the exploit requires that someone download and install software, although no password is required for the malware to run. An AppleScript command can be sent to the agent, which is handed off as a root-level shell command. A survey of security experts and the buzz among the Mac enterprise management community shows that this threat is a nonstarter.
The fact is that the Mac has not been a malware target, and it is safer than Windows from such threats. Create an iOS passcode Just to be sure that you can unlock your device locally if you do re-enable Find My iPhone, it's a good idea to set a passcode. Open the Settings app. Scroll down to Passcode. If you've never created a passcode before, toggle Turn Passcode On. Pro tip: Even if your employer or educational institution requires a complex passcode via MDM, you can still access the "quick entry" numeric keypad for your passcode Once your passcode is enabled and verified, you can set the timeouts for passcode access, which apps can be accessed from the lock screen, and more.

Mac account details at one of his computers and two of mine, one machine would show the other two computers in the Back to My Mac set, one would show none, and another would show just one. We were stymied. This is very helpful when configuring a firewall.
I determined that the Qwest DSL router lacked UPnP, which is a shame, but it had some very fine-grained controls for enabling incoming access to specific services by name for computers on the local network. It seems to pick up the Samba sharing name of those computers to identify them by IP address, even when the address changes; or I could assign a static private address, too. I turned on incoming access for the two ports mentioned in the Apple tech note, and now Back to My Mac works as expected. Mac password.
