Tag: Operating System

An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. The operating system is a component of the system software in a computer system. Application programs usually require an operating system to function.

Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.

For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers.

Examples of popular desktop operating systems include Apple OS X, Linux and its variants, and Microsoft Windows. So-called mobile operating systems include Android and iOS. Other classes of operating systems, such as real-time (RTOS), also exist.

A focus on foundation makes for an important but nigh-invisible update.
We're already used to the fact that complex cyberattacks use 0-day vulnerabilities, bypassing digital signature checks, virtual file systems, non-standard encryption algorithms and other tricks.
Sometimes, however, all of this may be done in much simpler ways, as was the case in the malicious campaign that we detected a while ago – we named it 'Microcin' after microini, one of the malicious components used in it.
Even as Windows 10 users grow, support calls are declining.

In the field of information security, sandboxes are used to isolate an insecure external environment from a secure internal environment (or vice versa), to protect against the exploitation of vulnerabilities, and to analyze malicious code.

At Kaspersky Lab, we have several sandboxes, we will look at just one of them that was customized to serve the needs of a specific product and became the basis of Kaspersky Anti Targeted Attack Platform.
A little while back we were investigating the malicious activities of the Freakyshelly targeted attack and came across spear phishing emails that had some interesting documents attached to them.

They were in OLE2 format and contained no macros, exploits or any other active content.
Virtual machines and hardware features will provide secrecy.
Results that had been obtained during research that we discussed in a previous article called for a more detailed analysis of the security problem, but now from within medical institutions (with the consent of their owners, of course).

The analysis allowed us to work on mistakes and give a series of recommendations for IT experts who service medical infrastructure.
Bringing a Siri watch face, workout motivation prompts, and more to the watch.
Containers offer the promise of portability and agility: the ability to move your applications from a developer's laptop to your internal datacenter, and out to different cloud providers with little trouble right? They offer the ability to spin up new, custom versions of your software to quickly meet contractual deadlines which were signed last minute, or maybe even provide your customers with self service.

They start faster, and are easier to move around than virtual machines. Right?Thatrsquo;s the goal, but portability and compatibility are not the same thing. Portability is a business problem, while compatibility is a technical problem. Portability can only be achieved by planning compatibility in different environments.

Adopting containers alone provides no guarantee of application compatibility. Why would it? Containers are really just a fancy way of packaging applications and all their operating system dependencies.To read this article in full or to leave a comment, please click here
