Security Software Enriches Troy City Schools Educational Experience by Providing Safe E-Mail
Based on the IT team's and the district's overall experience in combating spam over the last few years, they now advocate an approach that provides a series of tools such as filtering based on subject, content and sender. They also support reverse blacklisting technology for checking the IP addresses of the servers sending incoming mail to identify known or suspected spammers.To meet the need of monitoring and filtering all e-mail (both internal and external) Troy City Schools is also using concept-filtering technology, which is based on thesaurus matching and natural language processing, to identify and block spam in response to message content. This technique has provided the district with an additional layer of protection as it monitors much more than keywords. It also looks at the overall meaning of the message as an individual would to determine if an e-mail is legitimate or spam.
And to meet the ever-changing needs of students and the district itself, Troy City Schools has used its anti-spam solution to apply different rules to students and staff. For example, the system has been configured to ensure that students use e-mail only for school purposes. In addition, all messages with attachments can be easily quarantined, so network administrators can proactively fight back against known viruses.
Creating a Safe Environment
Over the last year, new types of attacks have emerged where viruses and spam converge to strike networks and user inboxes. The Sobig virus was one such attack where viruses struck the operating system and used e-mail to distribute spam. For Troy City Schools, the close integration of the anti-spam solution and the existing anti-virus system have enabled the district to quickly identify and filter out viruses disguised as spam. It has also protected its network against these new and increasingly frequent types of attacks.
For any organization deploying an anti-spam solution, one of the biggest challenges is administration. This is particularly true in the case of an educational organization, as IT budgets tend to be limited and administrators have many areas to oversee. Troy City Schools has been able to quickly configure the anti-spam solution to reduce the time spent reviewing e-mails that are quarantined, or those that are filtered and marked as possible spam.
Instead of reviewing all e-mails, the team has set up an automatic "white list" so e-mails with known addresses can bypass all or some filters, which significantly reduces the time spent reviewing quarantined e-mail on a daily basis. The end result is that the IT staff knows students aren't receiving offensive content, while saving time so other IT duties can be addressed.
At Troy City Schools, and for any school regardless of the age of its students, ensuring a safe environment for facilitating the education of all is the No. 1 priority. By providing e-mail, the district has been able to enrich the educational experience of its pupils, and having the right anti-spam technology in place enables the district to protect them. With the confidence that all users will only receive appropriate e-mail that is relevant to them, now parents can be comfortable with the fact that e-mail is, and will continue to be, a valuable tool in their child's education.
