Filtering
Summary
In order to comply with CIPA, we provide web filtering for staff
computers, public computers as well as devices that the customers
connect to the library's wireless network.
Policies
The filtering policies themselves (as in, the lists of what
types of content to block) are determined by the library system, not ESRL.
Antivirus
In addition to the filtering policy, all filtering also includes
some antivirus, antimalware and anti-phishing protection. This
protection is not expected to be perfect or comprehensive (none
ever is) and is not a replacement for antivirus software or common
sense.
Filtering on Staff Computers
ESRL suggests that staff computers, at a minimum, use our
"unfiltered" filter which includes only the virus/malware/phishing
protection. Staff computers may have stricter settings based
on local library system policy.
Filtering on Public Computers
The filtering on library owned public machines is managed
through Envisionware, and can be enabled or disabled (based
on local library policy) through Envisionware.
Envisionware - Dropping Filtering
Filtering on the Public Wireless
Filtering on the wireless segment cannot be disabled individually.
If a customer needs an unfiltered connection (and local
policy allows) they can be signed in to an unfiltered session
on a public computer.
We are unable to filter any device that has its own data plan, only devices that connect to the library wifi.
What you see when content is blocked
The screen that you will see if a page is blocked by the
filtering system looks like this:
The reason the page is blocked is given in bold, in this case "Block Example".
Reporting a problem or wrongly blocked site
ESRL makes every effort to make sure that legitimate sites are not blocked accidentally,
however no system is perfect. In the event that a legitimate site
is blocked, click the "View details" button to show more information,
then click the "Report to IT" link and contact Jim or Eli at ESRL
about the page. IT staff will not take any action about any page
reported unless a library staff member also contacts us about the report.
Categories
The "Category List" link in the block page details takes you to a page describing all the possible filtering categories.
