Remote Office / Branch Office (ROBO) scenario is usually challenging due to some constraints (like limited budget, lack of local IT people, limited IT resources and stuff, …) and some possible risks (like the bandwidth or latency assumptions could be wrong and not enought).

But in most companies the solution must provide same enterprise level services, like a right level of high availability, data protection, scalability (maybe not locally, but having more offices with similar solutions, …).

In most cases a two nodes solutions with a virtualization level could be enough, but what about the data protection aspects? Which kind of solutions could be suitable for a ROBO?

These people have gone above and beyond their day jobs to share their technical expertise and communicate the value of the specific vendor’s technologies to their colleagues and to the community.

Dirty COW (CVE-2016-5195) is a privilege escalation vulnerability in the Linux Kernel. The bug has existed since around 2.6.22 (released in 2007) and was fixed on Oct 18, 2016.

“A race condition was found in the way the Linux kernel’s memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.” (RH)
