Top 5 Most Secure Operating Systems

By -
The security of a given anything, even operating systems (OS), tends to be a difficult or even controversial issue to examine. The only, truly secure operating systems are those that lack contact to the outside world (e.g., a DVD player's firmware). As for any other OS, they'll inevitably have some sort of vulnerability or weakness that can be exploited. In fact, any networked OS can be exposed by careful abuse of its configuration—no exceptions. All the same, here are the top ten most secure operating systems on the planet today.


1.           OpenBSD

OpenBSD is a security-focused, free and open-source, Unix-like operating system based on the Berkeley Software Distribution. Theo de Raadt created OpenBSD in 1995 by forking NetBSD. According to de Raadt, OpenBSD is a research operating system for developing security mitigations.

2.           Linux

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged in a Linux distribution.

3.           Mac OS X

Building on the unique capabilities of Apple hardware, system security is designed to maximize the security of the operating systems on Apple devices without compromising usability. System security encompasses the boot-up process, software updates, and the ongoing operation of the OS.


4.           Windows Server 2008

On January 14, 2020, support for Windows Server 2008 and 2008 R2 ended. That means regular security updates have also ended. Don't let your infrastructure and applications go unprotected. We're here to help you migrate to current versions for greater security, performance and innovation.

5.           Windows Server 2000

During the Windows 2000 period, the nature of attacks on Windows servers changed: more attacks came from remote sources via the Internet. This has led to an overwhelming number of malicious programs exploiting the IIS services – specifically a notorious buffer overflow tendency

Types of Networks in Use Today

1. Personal Area Network (PAN) The smallest and most basic type of network, a PAN is made up of a wireless modem, a computer or two, phones, printers, tablets, etc., and revolves around one person in one building. These types of networks are typically found in small offices or residences, and are managed by one person or organization from a single device. 2. Local Area Network (LAN) We’re confident that you’ve heard of these types of networks before – LANs are the most frequently discussed networks, one of the most common, one of the most original and one of the simplest types of networks. LANs connect groups of computers and low-voltage devices together across short distances (within a building or between a group of two or three buildings in close proximity to each other) to share information and resources. Enterprises typically manage and maintain LANs. Using routers, LANs can connect to wide area networks (WANs, explained below) to rapidly and safely transfer data. 3. Wireless Local...
