Prevention and Mitigation
What is spam?
Spam is unwanted, unsolicited, and annoying content used for advertising, gaining information, or spreading malware. It can arrive via emails, phone calls, text messages, social media, and more. While not always malicious, spam can be harmful, causing more than just annoyance. Examples include racist text messages targeting students or offensive and sexually explicit emails.
What forms does spam take?
Spam can come in a variety of forms, including:
Inappropriate content: Messages designed to upset or shock the recipient, which may cause emotional harm or disrupt learning.
Advertising: Unsolicited messages from organizations inviting you to buy their products. While not necessarily harmful, they can be a waste of time and space.
Malware and phishing: Spam intentionally created to force users to perform harmful actions. This may include emails with malicious attachments or links to phishing websites.
"Too good to be true" offers: Messages that seek to trick users into revealing personal information in exchange for false prizes or benefits.
How does spam affect students?
Spam can negatively affect students in several ways:
Alienation of populations: Spam may contain messages that discriminate against or exclude certain groups.
Exposure to inappropriate content: Students may be exposed to disturbing content that they are unable to adequately process.
Class disruption: Students may become distracted and discuss the content of messages during lessons.
Inbox clutter: Spam can fill inboxes with unnecessary messages.
Exploiting naivety: Students may fall victim to financial or other scams due to their lack of experience.
Threats and fear: Spam can include threats (such as bomb threats) that lead to school closures, disrupting learning and creating anxiety.
Security breaches: Spam can be the starting point for ransomware attacks, which can result in learning loss, data leaks and costly recoveries.
How can spam be prevented?
There are several tools and tactics to prevent spam in schools:
Mobile Device Management (MDM): MDM helps ensure that school devices are properly configured and protected, enabling tracking of devices, users, and applications.
Email filtering: This is crucial to prevent spam from reaching users. Filters can detect spam based on content, sender, or other attributes.
Content Filter: Prevents access to malicious websites by blocking phishing links and other spam content.
Security software: Prevents malware downloaded through spam from running and takes necessary action once it is detected.
User Education: Teaching students and staff how to identify and respond to potential spam messages is crucial.
Implementation:
Jamf School: Jamf School is an MDM system designed specifically for schools, making device management easy and offering tools to help teachers manage distraction and spam issues in the classroom.
