Two more services have been launched with the aim of shoring up the security of the cloud, as its popularity sees it becoming increasingly targeted for attack.
File sharing company Box has launched a customer-managed encryption service, KeySafe, in a bid to give clients more control over their encryption keys without sacrificing the ease of use and collaboration features of Box. Meanwhile UK-based open source security vendor Black Duck has been recognised under IBM PartnerWorld’s ‘Ready for IBM Security Intelligence’ designation.
An Introduction to SELinux
Way back in kernel 2.6, a new security system was introduced to provide a mechanism for supporting access control security policies. This system was Security Enhanced Linux (SELinux) and was introduced by the National Security Administration (NSA) to incorporate a strong Mandatory Access Control architecture into the subsystems of the Linux kernel.
If you’ve spent your entire Linux career either disabling or ignoring SELinux, this article is dedicated to you — an introduction to the system that lives “under the hood” of your Linux desktop or server to limit privilege or even eliminate the possibility of damage should programs or daemons become compromised.
Some MacBooks have two graphics cards, the specific one this post is about is a MacBookPro8,2 (15-inch, Late2011) with an Intel HD Graphics 3000 and an AMD Radeon HD 6750M.
If you boot any OS into legacy BIOS mode (only option supported by – at this time – most recent release version 5.8 of OpenBSD), it is always the Radeon card that gets activated (except for Windows OS, where Bootcamp/drivers should handle the automatic switching just like in Mac OS).
You need an external USB WLAN card (or something else, if you want network access), because the internal one is not supported by OpenBSD.
