difference between security in linux and windows

The effects of such malware were always initially subtle, something you wouldn’t even notice, until the malware ended up so deeply embedded in the system that performance started to suffer noticeably. Another new feature in Service Pack 2 is the ability to uninstall additions to a browser, which potentially places more responsibility on the end user who may have to look at many plug-ins and uninstall the right ones. Red Hat’s system update tool, called up2date, and works with Red Hat Network to enable users to download and install new packages. Every step can be re-run by users, and this enables incremental security on a meta level. Exec-shield enables protection against a variety of exploits that attempt to overwrite data structures or insert code within these structures. Because the bottom line is that every decision you make regarding your systems will affect your security, even the operating system your users do their work on. Linux is somewhat superior due to continuing security issues with Microsoft IIS and Exchange/Outlook. Patch management under Linux is often easier because of the separation of kernel and user space, which reduces the number of potential significant security exploits. Microsoft is taking strides to redesign the security of its products and provides patches for its installed base. Another major change with Linux v2.6 is the addition of Linux Security Modules (LSM), which allows users to add additional security mechanisms to a Linux distribution without needing to patch the kernel. The challenge in evaluating Windows and Linux on any criteria is that there is not a single version of each operating system. Formulate discipline on the part of the IT manager and system administrators who need to understand how to apply security best practices. Since Linux is open source, unlike Windows, there is unrestricted access to the history of all of the source code. That had a lot to do with why PC World came right out and said Linux is more secure. Microsoft participates in open standards but has handling, Trusted Platform Module, Trusted Computing One striking thing about the infestations was that I was never specifically targeted by the miscreants; nowadays, it’s as easy to attack 100,000 computers with a botnet as it is to attack a dozen. This matters because the ability to make either operating system more secure varies depending on architectural design. Fundamental changes in Linux and Windows security. OpenAV, Panda, TrendMicro, firewall capability The lone teen hacker that once dominated the public imagination has been supplanted by well-organized networks of criminals and shadowy, government-funded organizations with vast computing resources. However, there is distinction between hardening infrastructure and hardening the operating system. Microsoft’s version of Kerberos is not completely interoperable with the standard, so IT managers who use Microsoft Kerberos will find it harder to deploy and manage Kerberos across a heterogeneous IT environment and will prefer an all-Windows IT infrastructure. Software Stack, instrumentation, attestation, Trusted Platform Module device driver open Many Linux users depend on non-open source drivers and other binary modules from hardware manufacturers and systems providers. The following analysis is by no means comprehensive and is intended as a starting point for end-user evaluation. In contrast, most Microsoft system administrators use a GUI that can be easy to use but also allow mistakes in configurations easily. What is most outstanding is Microsoft’s focus on enhancing security through improved usability. Windows 98, Windows NT, Windows 2000, Windows 2003 Server, and Windows CE are just a subset of Microsoft’s offerings. A variety of access control mechanisms have been built on top of LSM, including the United States’ National Security Agency’s (NSA) Security Enhanced Linux (SELinux). Next: Key findings: Linux vs. Windows security capabilities, Key findings: Linux vs. Windows security capabilities. Communication by example: Which methods do high-performing open source communities use? exec-shield, McAfee, Symantec, Check Point, IIS, Among its improvements have been rewriting and re-rewriting its operating system codebase, adding its own antivirus software system, improving firewalls and implementing a sandbox architecture, where programs can’t access the memory space of the OS or other applications. default has been emphasized lately, Common Criteria Certification, flaw handling, Linux has achieved EAL3 and has good flaw The Linux v2.6 kernel provides protection against these dangers by placing restrictions on the level of access a non-open source driver or module has to the kernel. “Linux is the most secure OS, as its source is open. If your systems fall within that 88%, you’re probably aware that Microsoft has continued to beef up security in the Windows system. This will reduce the risk of an end user enabling a virus or worm by launching an executable. How secure an IT infrastructure is will vary not only based on the Linux distribution and Microsoft product and service pack deployed, but also by what patches customers choose to implement. This feature promotes stability, but does not place any new restrictions from a security point of view to stop a determined hacker from writing a malicious module.
