- 2. T heTHREAT wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww VDisabling and hacking networks are a major threat to computers at school, home, businesses, or in public places. VAnother concern is keeping all data and software protected from corruptions. VKeeping email free from spam is also a part of network security.
- 3. Common Misconceptions wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww VOne major misconception is that only those that are computer illiterate are going to be attacked. Computer specialists are affected by network security as well. The Y2k was a big scare for those. VAnother misconception is those that believe the school districts can stop malicious attacks and theft of information. Districts have made technology unpleasant, nonflexible, and difficult for instruction to take place in the classroom.
- 4. T he realities Of Network security wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww VCost: Keeping the network secure is a high price to pay. VSensitive and Confidential Information: District networks usually contain personal information, grades, assessments of both students and teachers. Many legal implications can come about if confidentiality is breached. VStudent Safety: Administrators have to make certain that all students are protected from harmful content or situations VTeacher Access and Productivity: Some districts have provided an extremely secure firewall so teachers can have access to virtual private networks (BPNs) from school and home. VAccess and Functionality: This would entail teachers being provided with a server space for educational websites and Internet access. Teachers need the capability to be able to transport work from school and home computers.
- 5. Common Responses wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww V Some common responses include: Restricting Permissions: Users are allowed to complete certain functions. This can be overridden with a password. V Blocking Instant Messaging (IM): Misuse of the network and the content that can be viewed through IM. Many districts have disable this feature. V Disabling of USB Drives: Illegal downloading and file sharing are the main reasons for USB drives to be disabled. V Firewalls, Antivirus, and Spam Filters: Schools are using antivirus software which are installed on the proxy server. V Policies and Procedures: The security policies include the roles and responsibilities of network users, regular maintenance, and implementation of security assessments. V Restricting Server Use: Some districts forbid the use of the server for classroom and teacher websites. “Teachers are simply not allowed to upload any files or create access points on the web.” (Robinson, Brown, & Green, 2010). These district are trying to prevent network security breaches from what teachers are posting that can accidentally or purposefully harm the network.
- 6. A few Recommendations wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww V Network Rights Strategies: Acceptable Use Policies (AUPs)- contracts between the school and the students and teachers to keep the school’s network safe. V Balance Instructional Needs with Desktop Security: Teachers making sure software being installed is legal. V Server Space and Network Use: This will enhance teaching by allowing teachers to use the web to utilize Web 2.0 tools and create websites, etc. for student learning. V Monitor Student Use: Districts use software that monitor all the users’ activity while using the internet. V Firewalls: Districts need to invest in buying a good firewall that will have fast Internet access while still blocking the viruses and protecting that servers. V Security Assessments: District should have a security assessment plan that include knowledge of security measures, policies, and procedures, characteristics of the network and regular updates, and how the firewall works. V Secure Passwords: Teacher should create and memorize passwords.
