How to Keep a Comcast Gateway Secure
Encrypting the information that is transmitted through the air is the best way to protect communications from eavesdroppers. The two main types of encryption are Wi-Fi Protected Access (WPA) and Wired Equivalent Privacy (WEP). WPA2 is the best choice but many older routers do not have this option. If your router doesn't have WPA2, you should upgrade.
To limit access to your router it is recommended that you use a strong password that isn't freely shared or used anywhere else.
This guide will walk you through the process of protecting your Comcast wireless network.
1 Password Best Practices
Wherever possible, you should pick a password that is impossible to guess and is also resistant to brute-force attacks.
Password Dos and Don'ts
- Passwords should be long, 8-12 characters or more.
- Passwords should be something easy for you to remember, but hard for others to guess or lookup.
- Passwords should have lots of different character types: upper and lower case letters, numbers, and symbols.
- Replacing letters with symbols is a simple way to achieve this: use @ for a, and ( for c, as example.
- Passwords are personal, most services have a way to create a 'linked' account or share services with trusted friends and family.
- Change passwords regularly. Every 90 to 180 days; this helps keep your accounts from being compromised long-term.
- If you must write down a password or make note of it, do so only in specially designed programs, or keep and hold the physical copies with the same care and respect you would a social security card or birth certificate. Remember; anyone with your password "is you".
- Don't use short passwords; computers can guess them very easily.
- Don't use a common word you can find in a dictionary.
- Don't use information that can be looked up or guessed, such as a birthday, anniversary, or pet's name.
- Don't use the same password for everything. If one password is compromised, all of the same ones are compromised across all your accounts.
- Don't share passwords. People with your password "are you" to a computer system, or a service.
- Don't keep the same password forever. Assume that, at some point, it will be guessed, seen, or otherwise compromised, and it must be changed.
- Don't write down passwords in the open, or save them in non-encrypted files on your computer.
