Do You Blame Users For IT Security?

Posted on in Categories Linux, Linux desktop, Security, Sys admin, UNIX, Windows, windows vista last updated March 12, 2009

An interesting article published by security guru Bruce Schneier:

Blaming the victim is common in IT: users are to blame because they don’t patch their systems, choose lousy passwords, fall for phishing attacks, and so on. But, while users are, and will continue to be, a major source of security problems, focusing on them is an unhelpful way to think.

=> Blaming the user is easy – but it’s better to bypass them altogether

Uninstall IE8 Under Windows 7

Posted on in Categories Security, Windows, Windows server, windows vista last updated March 5, 2009

IE (Internet explore) was first released as part of the add-on package Plus! for Windows 95 in 1995. IE is fully integrated into MS operating system. IE has been subjected to many security vulnerabilities such as spyware, adware, and computer viruses. Removing Internet Explorer does have a number of consequences. Applications that depend on libraries installed by IE will fail to function, or have unexpected behaviors. A just-leaked build of Windows 7 lets users remove Internet Explorer (IE), the first time that Microsoft has offered the option since it integrated the browser with Windows in 1997.

Security Through Obscurity: MAC Address Filtering ( Layer 2 Filtering )

Posted on in Categories data center, fedora linux, FreeBSD, Gentoo Linux, GNU/Open source, Hardware, Iptables, Linux, Networking, RedHat/Fedora Linux, Security, Ubuntu Linux, UNIX, Windows, windows vista, Wireless networking last updated February 17, 2009

MAC Filtering (layer 2 address filtering) refers to a security access control methodology whereby the 48-bit address assigned to each network card is used to determine access to the network. Iptables, pf, and IPFW can block a certain MAC address on a network, just like an IP. One can deny or allow from MAC address like 00:1e:2a:47:42:8d using open source firewalls. MAC address filtering is often used to secure LAN or wireless network / devices. Is this technique effective?

Debunking the "Linux is virus free" Myth

Is Linux is virus free? The author of foobar blog provides some insight about the same. Linux users can’t just catch a virus by email or downloading malware from the Internet, contrary to “those Windows users”. From the foobar blog post:

Then you save an email attachment under Linux, the execute flag is normally NOT set and thus, the file can’t be executed just by clicking on it. So, no luck?

Why Did You Switch From IE ( Internet Explorer ) ?

Posted on in Categories Ask nixCraft, Linux, Linux desktop, UNIX, Windows, Windows server, windows vista last updated February 11, 2009

I was going though my server logs / Google Analytics settings and found that over 60% users are on MS-Windows. However, each and every month visitors are switching to Firefox or Google browser and so on. So I would like to know your reasons for making switch from IE to another browser. Why did you switch and which browser did you switch to?

Woman Blames Dell and Ubuntu For Missing Online School Classes

Posted on in Categories GNU/Open source, Linux, Linux desktop, Ubuntu Linux, Windows, windows vista last updated January 15, 2009

Another clueless woman has claimed that Dell computer and Ubuntu Linux have kept her from going back to school via online classes. According to a story – a woman bought a Dell computer and realized she ordered it with the Ubuntu Operating System rather than MS-Windows. She tried to change OS to Windows but Dell refused. Her Verizon High-Speed Internet CD won’t load, so she can’t access the internet. She also can’t install Microsoft Word, which she says is a requirement for MATC’s online classes. As a result, with no internet and no Microsoft Word, Schubert dropped out of MATC’s fall and spring semesters. The full story is here including followup.

Now, I’ve no idea about Verizon’s modem and DSL connection but most A/DSL provider modem (router) comes with an Ethernet port. There is no need to use wizard or CD based installer. Other software such as MS-Word can be replaced with OO (I submitted all my school work using OO office writer and no one noticed the difference… ). Further both Verizon and MATC ready to help:

Verizon says it will dispatch a technician to try to assist her accessing the internet without using the Windows-only installation disk.

MATC also says it promises to accept any of Schubert’s papers or class documents using whatever software she has installed.

So what is the problem here?

Tutorial: OpenOffice.Org Mail Merge

Posted on in Categories fedora linux, Gnome, GNU/Open source, Howto, Linux, Linux desktop, OS X, Tips, Ubuntu Linux, UNIX, Windows last updated January 14, 2009

openoffice

Mail merge is a software function describing the production of multiple documents from a single template form and a structured data source. This helps to create personalized letters and pre-addressed envelopes or mailing labels for mass mailings from a word processing document which contains fixed text, which will be the same in each output document, and variables, which act as placeholders that are replaced by text from the data source. The data source is typically a spreadsheet or a database which has a field or column matching each variable in the template. When the mail merge is run, the word processing system creates an output document for each row in the database, using the fixed text exactly as it appears in the template, but substituting the data variables in the template with the values from the matching columns.

This technique of merging data to create mailshots gave rise to the term mail merge. OpenOffice.Org has a in built software mail merge feature.

If you haven’t tried OpenOffice.org’s mail merge feature because you find it confusing or difficult to use, you are in luck. Mail Merges in OpenOffice.org and StarOffice provides a detailed description of the mail merge feature from start to finish. Among other things, it shows how you can use the mail merge to create letters, labels, and envelopes.
