The Security

Linux is entirely open-source, unlike other operating systems, meaning one has thousands of people around the globe are tearing apart the Linux source code on a daily basis [37]. The open-source community looks for every security vulnerability and issues a security patch [37]. The more people you get to look at and review your code, the better, which is the case in the Katheer OS. On the contrary, when you only have a select team of people (as with Windows and macOS) to review code, you're definitely going to run into some significant issues, and you will have far more vulnerabilities than the global crowd-sourced one.
Many industry experts say Linux could be safer than Windows and macOS. Linux has advanced options to sandbox any process, which is why some analysts and users view Linux as more secure than Windows and macOS. Linux implements various aspects of security that are intended to complement each other. Instead of looking at anti-malware or firewalls, Linux recognises that permissions solve 99% of the issues in cybersecurity [37].
Katheer Project will apply the Security-Enhanced Katheer operating system by default, which implements a diversity of security policies, including forced access controls. Katheer will render a hardening wrapper using compiler features like position-independent executable (PIE). Contrary to certain beliefs, the open-source nature of the Katheer OS helps patch security issues very quickly and spot any security flaws due to its collaborative nature. Moreover, Katheer OS will not give its users admin access by default and therefore limits the damage that users can do by clicking on links that could be malicious. Finally, many companies already use Linux operating systems like the Red Hat Enterprise Linux, which is specifically hardened for data security and will use the Katheer OS for the same reason.
In addition to the above, the Katheer OS will have a built-in security application, the K Guard Endpoint Security. K Guard Endpoint Security provides next-generation, multi-layered protection against all types of cyberthreats on the Katheer OS that detects known and advanced threats, even in memory or boot sectors. It delivers reliable protection with minimal impact on performance and offers complete protection in hybrid environments, ensuring all systems are managed and protected all the time. K Guard Endpoint Security provides built-in technologies to eliminate redundant scanning, protect valuable data and business applications, identify and block the latest emerging threats, and deliver optimal security with minimal impact on other applications or overall system performance. K Guard Security Network is an advanced system that processes anonymised threat data from millions of nodes worldwide, using sophisticated data science technologies to deliver near real-time threat intelligence to every user.
This agility means that even in zero-day attack situations, where threat information is not yet available to the endpoint, K Guard Security Network works with K Guard Endpoint Security for the Katheer OS to stop threats. Big data processing of massive volumes of threat metadata from suspicious files makes it possible to make rapid, accurate decisions about their safety without analysing their content - with short response times; it's a significant additional layer of security.
K Guard will have the Behavior Detection feature, which provides proactive defences, identifying and extracting suspicious behaviour patterns and effectively protecting your system against advanced threats. It will also have the Auto-scan feature for newly connected storage devices that don't allow malicious programs that exploit operating system vulnerabilities to replicate themselves via removable drives. K Guard can also scan network ports and monitor web traffic for attempts to visit phishing websites and block access to them.
