All software media should be backed up regularly to ensure that no data are lost. Periodic backups stored in a secure off-site location will make it possible to recover quickly from a catastrophe on site. The agency should take into account regional peculiarities when storing backups off site. For example, in areas prone to earthquakes, media should not be stored in high-rise buildings; in areas prone to flooding, media should be stored in a facility away from the flood plain. Some recommendations for software security are as follows: store software media in a locked cabinet within a proper environment; retain off-site storage for backups of installation media; test the process for restoring software; retain off-site storage of licensing and application documentation; maintain and back up licensing management and related documentation; allow access to applications through the use of network security settings to only those groups/users that require access; implement a software-auditing package to ensure license compliance and to ensure that no unauthorized software has been installed on the agency's system; standardize applications across the agency; use virus-scanning software with frequent definition updates (network-attached appliances are available for e-mail virus scanning); and use spamming prevention or filtering software to prevent unauthorized entry of email (e.g., do not allow web-based e-mail programs, such as Hotmail?). Unauthorized e-mail entry is a serious vulnerability that can lead to the entry of viruses into the network through a "back door." Securing the Network The same security procedures in place for server hardware apply to equipment that supports the network, including switches, hubs, routers, firewalls, access points, cabling, etc. Network equipment should be installed in an environment with proper ventilation and power requirements and should be protected from unauthorized access. The agency should place the equipment in dedicated building spaces. Access should be limited to staff that have a key, combination lock, key card, or other security device. Some basic precautions for securing network equipment are as follows: limit access to network equipment to authorized individuals; do not allow users to install unauthorized network equipment; use secure, encrypted passwords for "root" access (access to the "root" enables users to control entire systems or servers); and ensure proper cabling and cable protection by running cabling under a false floor, avoiding running cable over fluorescent lighting fixtures, and staying within cable/fiber length requirements. A fundamental action the agency can take toward maintaining a secure and reliable network is to hire a qualified individual to serve as the network administrator. Network administration is not a task for the average high school teacher/technology coordinator. Many agencies, however, cannot afford to hire an experienced network administrator for each school and often do rely on faculty for this position. If a teacher/coordinator is to be responsible for a school network, the agency must recognize training and professional development as priorities. Agency network policies and procedures should be clearly defined. These policies should be made readily available to anyone responsible for maintaining the network. Listed below are some items to consider for agencies managing their own networks. The responsibilities of a network administrator are, for the most part, very technical in nature. This reinforces the point that training is critical for anyone with the responsibility of running a network. Agencies should assign one individual to be responsible for network administration (and one individual as his/her backup); limit access to network equipment console screens by login credentials (either on the piece of network equipment or using an authentication server); limit access to Telnet sessions on network equipment through access lists and/or authorized workstations where only authorized users have access; limit protocols running on the network equipment; configure login banners to warn intruders of possible prosecution; use firewalls to prevent unauthorized access between external and internal systems; use unroutable IP addressing schemes within the internal network [Class A - 10.0.0.0-10.255.255.255 (10/8 prefix), Class B - 172.16.0.0-172.31.255.255 (172.16/12 prefix), Class C - 192.168.0.0-192.168.255.255 (192.168/16 prefix)]; utilize intrusion detection systems (IDS); inspect, analyze, and maintain router audit logs; provide ingress and egress access control list (ACL) filtering to prevent IP spoofing; and eliminate unauthorized network resource use by monitoring network traffic and bandwidth usage and protocols to ensure adequate bandwidth for applications; removing the ability to download unauthorized files; restricting remote access to network resources to authorized individuals with types of remote access including dial-up connections, virtual private networks (VPN), and Point-to-Point Protocol (PPP); implementing a multiple-authentication policy for authorized users or integrating into an authentication server; eliminating any "back-door" types of equipment (e.g., user modems installed on desktops); maintaining proper encryption of remote connections to ensure confidentiality; and using VPN technology with proper encryption to gain connectivity through the public networks such as the Internet. Wireless Networks Wireless communication is a rapidly evolving technology that is becoming increasingly prevalent in everyday life. The built-in security for wireless computer networks, however, is relatively weak. Technology coordinators need to pay particular attention to secure these networks properly, and the network administrator must keep up to date on emerging methods for securing wireless networks. Some security measures to consider when planning a wireless network are as follows: shut off Service Set Identifier (SSID) broadcasting and use an SSID that does not identify the agency by name; select a hardware vendor and software revision that has fixed the problem of randomization of initialization vectors (IVs); utilize applications like AirSnort or BSD-AirTools, which will be less likely to crack the agency's Wired Equivalent Privacy (WEP) keys; use 128-bit WEP and change WEP keys regularly. Select a vendor that provides a tool to rotate the agency's WEP keys; disallow access to resources at the first router hop other than the agency's VPN server, which ensures that the only host available to the wireless segment is the VPN server until a tunnel is established; place wireless access points on a dedicated virtual local area network (VLAN). Do not mix wired and wireless clients on the same LAN segment; implement a policy that limits the amount of connectivity a wireless client has to the agency's network. Assess whether students/faculty/staff need more access than TCP/80, TCP/443, etc.; utilize personal firewalls on the agency's workstations; and disable automatic IP address assignment (DCHP). If hackers are able to guess or crack the agency's WEP keys, they will not be able to access the remainder of the internal network because VPN and VLAN architecture with access lists will allow only authorized VPN clients to be routed to the network from a wireless VLAN segment. Hackers will be able to attack clients on the same subnet, however, and if one VPN connection is left up, it could be abused to access the rest of the internal network. back to top 2b1af7f3a8
