Computing @ York http://computing.yorku.ca Fri, 18 Apr 2014 04:35:10 +0000 en-US hourly 1 Secure Remote Access (VPN) Update – Tuesday April 22nd, 7:30am – 8:00am http://computing.yorku.ca/2014/04/secure-remote-access-vpn-update-april-22nd-730am-800am/ http://computing.yorku.ca/2014/04/secure-remote-access-vpn-update-april-22nd-730am-800am/#comments Thu, 17 Apr 2014 18:32:05 +0000 http://computing.yorku.ca/?p=11164 On Tuesday April 22nd, between 7:30am - 8:00am, the Secure Remote Access (VPN) service will be migrated to a new Junos Pulse VPN client.  During the migration window there may be a loss of Secure Remote Access (VPN) service to connected users. The Junos Pulse VPN client supports a wide range of mobile tablets and phones.   

Beginning Tuesday April 22nd a listing of supported platforms and information on how to download, install and configure Junos Pulse VPN will be available at:   
        http://computing.yorku.ca/faculty-staff/internet-access/secure-remote-access/

PLEASE NOTE:

The Junos Pulse VPN client must be manually downloaded and installed from: http://computing.yorku.ca/faculty-staff/internet-access/secure-remote access/    

The Junos Pulse VPN client does not support Linux systems. Linux OS users will    continue to use  Network Connect with a supported browser for SSLVPN remote access. 

The https://vpngateway.yorku.ca/voicemail SSL Web only services will be unaffected and will continue to use a supported browser.

Please direct any questions or concerns to UIT Client Services -

Heartbleed Bug – Security Threat – posted on April 9th, 2014 http://computing.yorku.ca/2014/04/security-threat-heartbleed-bug-posted-on-april-9th-2014-2/ http://computing.yorku.ca/2014/04/security-threat-heartbleed-bug-posted-on-april-9th-2014-2/#comments Wed, 09 Apr 2014 20:50:47 +0000 http://computing.yorku.ca/?p=11041 What is it?

Earlier this week a serious computing vulnerability called the The Heartbleed Bug was discovered. This weakness affects a large number of websites allowing an attacker to steal login information and other data that would normally be protected by SSL protocol for communication (ie. pages that start with https). According to a research firm, Netcraft,as many as 500,000 servers may be affected globally. Further information about this can be found at:

http://cacr.iu.edu/news/631

How does it affect York University?

UIT has been working to identify and notify system owners that may be vulnerable to this issue. Affected servers need to be updated to the latest version of OpenSSL. Fortunately, many important York systems, such as Passport York, were never at risk for this vulnerability, and many systems have already been updated. Network-based defenses are in place to help prevent threats from outside York’s campus network.

At this time, there is no indication the vulnerability has been used to compromise data from any York site, however there is code available in public to potentially do so, and there are indications that the bug has existed for 2 years before being publicly known.

What can you do?

Clients are advised to take the following actions:

  • Via normal mechanisms, change your passwords for any York application that you may be concerned about, or deal with highly confidential information.
  • Most major websites will have dealt with this problem by now. To be safe, you should change all your passwords now, just in case they were ever captured in the past. You can always contact the external sites to confirm.
  • Be vigilant with fraudulent phishing messages that ask you to change your password by clicking on a link in an email. There are already indications that criminals are using the opportunity to create targeted “phishing” email messages to trick people into divulging passwords via email or directing people to a malicious/fraudulent web site.

Questions or concerns can be directed to UIT Client Services.

Windows XP is no longer supported by Microsoft – posted on April 9th, 2014 http://computing.yorku.ca/2014/04/windows-xp-is-no-longer-supported-by-microsoft/ http://computing.yorku.ca/2014/04/windows-xp-is-no-longer-supported-by-microsoft/#comments Wed, 09 Apr 2014 20:36:16 +0000 http://computing.yorku.ca/?p=11029 On April 8th 2014, Microsoft has ended support for Windows XP operating system and will no longer provide updates, including security and critical patches for this operating system. Hence a computer running Windows XP has more chances of being vulnerable to virus and security threats. See suggestions below to protect your XP computer:

Office Computers using XP:

I.T. Service providers at York have been working with the community for many months to migrate computers from Windows XP to Windows 7. If you are using Windows XP on your administrative computer then please contact your local desktop support.

Home and Personal Computers using XP:

  1. Avoid using the XP computer for surfing websites or reading your email as these are the most common ways of computers getting infected by virus and other malware. Otherwise, only visit well-known bookmarked or favourite sites and do not open attachments or click on links in email.
  2. Ensure that Windows XP firewall is turned on. For further information you can visit Microsoft Windows XP Knowledge base.
  3. Ensure that Symantec Anti-Virus is installed on the computer and that it is updated and full scans are run regularly.
  4. Instead of using any Microsoft software that comes pre-installed in your computer such as Internet Explorer, Windows Mail etc use alternate software such as Firefox (browser) or Thunderbird (email reader). Remember Microsoft will not provide any further patches for any software that comes pre-installed with your Windows XP machine.
  5. Keep all applications up to date. eg. Adobe Acrobat, Adobe Flash, Java etc.
  6. Use an account which does NOT have administrator privileges. If an account with admin priviledges is compromised then the hacker / attacker can compromise the entire computer. For further information you can visit Microsoft Windows XP Knowledge Base.
  7. Download and install Microsoft’s EMET (Enhanced Mitigation Experience Toolkit). This can prevent some (not all) vulnerabilities from being exploited.

NOTE: In spite of following all the suggestions above, your Windows XP computer may still not be safe from future virus and security threats. Upgrading to a supported version of Microsoft Windows or any other operating system will be the best way to help secure your computer and data.
