Securing Operating Systems Through Fine-grained Kernel Access Limitation for IoT Systems
With the development of Internet of Things (IoT), it is gaining a lot of attention. It is important to secure the embedded systems with low overhead. The Linux Seccomp is widely used by developers to secure the kernels by blocking the access of unused syscalls, which introduces less overhead. However, there are no systematic Seccomp configuration approaches for IoT applications without the help of developers. In addition, the existing Seccomp configuration approaches are coarse-grained, which c…

The giant, remote-controlled vehicle
— somewhere between a tractor trailer, a tank and a Zamboni in appearance
— slowly rolled across the dry, brittle grass growing between the tangle of freeways making up the 101 and 23 interchange in Thousand Oaks.
Inside the beast, fire churned.
And as it rolled over the land, that fire incinerated any brush it encountered,
leaving only a thin smoke cloud billowing from the top of the machine, some flashes of orange and red fr…

Shrinking the Kernel Attack Surface Through Static and Dynamic Syscall Limitation
Linux Seccomp is widely used by the program developers and the system maintainers to secure the operating systems, which can block unused syscalls for different applications and containers to shrink the attack surface of the operating systems. However, it is difficult to configure the whitelist of a container or application without the help of program developers. Docker containers block about only 50 syscalls by default, and lots of unblocked useless syscalls introduce a big kernel attack surfa…

#Orwell wrote about the #JustTransition in 1947 ("Toward European Unity"):
«The European peoples, and especially the British, have long owed their high standard of life to direct or indirect exploitation of the coloured peoples. [...] But it is by no means certain that we can afford these th…

RL Is a Hammer and LLMs Are Nails: A Simple Reinforcement Learning Recipe for Strong Prompt Injection
Prompt injection poses a serious threat to the reliability and safety of LLM agents. Recent defenses against prompt injection, such as Instruction Hierarchy and SecAlign, have shown notable robustness against static attacks. However, to more thoroughly evaluate the robustness of these defenses, it is arguably necessary to employ strong attacks such as automated red-teaming. To this end, we introduce RL-Hammer, a simple recipe for training attacker models that automatically learn to perform stro…
