Don't use Internet Explorer

Microsoft Security Advisory 2963983 (CVE-2014-1776) is a serious Vulnerability in the Internet Explorer web browser that could Allow Remote Code Execution. Microsoft is aware of limited, targeted attacks that attempt to exploit a vulnerability in Internet Explorer 6, Internet Explorer 7, Internet Explorer 8, Internet Explorer 9, Internet Explorer 10, and Internet Explorer 11.
The vulnerability is a remote code execution vulnerability. The vulnerability exists in the way that Internet Explorer accesses an object in memory that has been deleted or has not been properly allocated. The vulnerability may corrupt memory in a way that could allow an attacker to execute arbitrary code in the context of the current user within Internet Explorer. An attacker could host a specially-crafted website that is designed to exploit this vulnerability through Internet Explorer and then convince a user to view the website.
For more information on Microsoft Security Vulnerability 2963983, please visit:

Skyward and other vendors are recommending that everyone use an alternate web browser until Microsoft releases a patch.

Do you have your new password ready?

Do you have your fifteen character password ready?

This is a reminder that starting July 15, all staff must have a long password. New passwords must be at least fifteen characters long and contain at least one number and symbol.

The good news? Your password will not expire, so you won't ever have to change it unless it gets cracked.

If you are wondering why, or need help creating a password that long that you can also remember, please read "How to choose a good password" on our documentation site.

On July 15, we will switch our servers from Novell to Microsoft. This means your current Novell password will no longer work, and you will have to start using a new one. Because we cannot see or export your current passwords, we will assign you a new one that you must start using on July 15.

Before the end of school, you will receive a piece of paper which will contain your new password. On July 15, you will need to start using this new password. You may want to change it to something you can remember more easily, but you must use the password issued to you at least once to log in and change your password.

If you have questions, please feel free to contact me or read the detailed explanation at http://sites.google.com/a/oregonsd.net/technology-integration-tool/Home/passwords (staff login required).
