Implementation of the high-security remote access concept

Posted on

Continuing the series of articles on organizing Remote-Access VPN access, I cannot help but share an interesting experience of deploying a highly secure VPN configuration. One client posed a non-trivial challenge (there are quite a few imaginative thinkers in Russian villages), but Challenge Accepted—creatively implemented.

Loneliness for rent. 1. Fantasy

Posted on

Open spaces have always annoyed me. Stuffy air. Struggling for a draft. Constant background noise. Everyone around needs to communicate. You are always in headphones. But even they don’t help. Dozens of colleagues. You sit facing a wall. Everyone is watching your screen. And at any moment, someone tries to distract you. Sneaking up from behind. Now—working from home in quarantine. Lucky to be able to work remotely. With […]

6 key questions when moving a business to the cloud

Posted on

Due to the forced break, even large companies with developed IT infrastructures find it challenging to organize remote work for their staff, while small businesses simply lack the resources to deploy the necessary services. Another issue is related to information security: opening access to the internal network from employees' home computers is risky without specialized corporate-class products. Renting virtual servers does not require capital investment […]

A vulnerability in the vhost-net driver within the Linux kernel

Posted on

A vulnerability (CVE-2020-10942) has been identified in the vhost-net driver, which provides virtio net functionality on the host environment, allowing a local user to initiate a kernel stack overflow by sending a specially crafted ioctl(VHOST_NET_SET_BACKEND) to the /dev/vhost-net device. The issue arises from the lack of proper validation of the sk_family field content in the get_raw_socket() function code. Preliminary reports indicate that the vulnerability could be leveraged for a local DoS attack through kernel crash calls (details are […]
