Broadband, a high-speed network connection, offers an “always-on” Internet experience, contrasting with traditional “dial-on-demand” services. This constant connectivity increases security risks, making it crucial for every user to configure their broadband connection securely. Without proper security measures, your computer can be compromised and used for malicious activities, potentially affecting other systems. Here’s how to protect your broadband Internet connection and ensure safe usage.
Broadband Security Threats
-
Always-On Connection Risks
- Trojans and Backdoors: Malicious software can infiltrate your system, allowing unauthorized access.
- Denial of Service (DoS): Your network can be targeted to disrupt service.
- Intermediary for Attacks: Compromised systems can be used to launch attacks on others.
- Hidden File Extensions: Malicious files can disguise themselves to avoid detection.
- Chat Clients: Instant messaging apps can be exploited for malicious activities.
- Packet Sniffing: Hackers can intercept and analyze data transmitted over your network.
-
Vulnerable Default Configurations
- Out-of-the-box settings are often insecure, making it essential to modify these configurations.
Guidelines for Securing Broadband Internet Access
1. Download Drivers from Legitimate Sources
- Always get broadband drivers from the manufacturer’s recommended websites.
2. Regular Firmware Updates
- Keep your modem’s firmware up to date to protect against vulnerabilities.
3. Use Manufacturer-Supplied Power Adapters
- Ensure you’re using the correct power adapter to avoid power issues.
4. Enable Filters for Terminal Adapter Modems
- Filters reduce unnecessary noise during transmission, enhancing performance.
5. Change Default Administrator Credentials
- Modify the default admin username and password to prevent unauthorized access.
6. Assign Static IP Addresses
- Turn off DHCP and assign static IP addresses to reduce the risk of IP address theft.
7. Enable MAC Address Filtering
- Restrict network access to specific devices by allowing only their MAC addresses.
8. Enable Wireless Security
- Choose and enable a wireless security protocol (WPA/WEP) with a strong protection key.
9. Change the Default SSID
- Modify the default network name to prevent easy identification and misuse by attackers.
10. Use End Point Security Solutions
- Protect your devices with antivirus, antispyware, and desktop firewall software.
11. Enable Firewalls
- Activate firewall features on both your modem router and connected computers.
12. Turn Off Modems When Not in Use
- Shut down your network during extended periods of inactivity, such as travel.
13. Disconnect USB Modems After Use
- Remove and disconnect USB broadband modems when not in use.
14. Monitor Bandwidth Usage
- Install tools to keep track of your broadband Internet bandwidth usage.
15. Enable SSH for Remote Administration
- Use a secure channel for remote administration to prevent unauthorized access.
