What practice improves security for wireless remotes in gate systems?

• A. To minimize cost; reuse default codes
• B. It has no impact on security; use simple codes
• C. Prevents spoofing and unauthorized access; use rolling codes, encryption, device pairing, and regular code changes
• D. To increase range by using no encryption

Answer: (C)

Wireless gate remotes are at risk of spoofing, interception, and unauthorized access. The best way to protect them is by combining several security measures that address different attack methods: rolling codes, encryption, device pairing, and regular code changes. Rolling codes ensure that each press uses a new code, so captured codes can’t be reused to gain access. Encryption keeps the communication private so an eavesdropper cannot understand or manipulate the signal. Device pairing links only trusted remotes to the gate receiver so unfamiliar remotes can’t operate the gate. Regularly changing codes reduces the damage window if a code or remote is compromised.

Using default or simple codes is insecure because those codes are easy to guess or copy. Trying to extend range by removing encryption only weakens security, making it possible for attackers to intercept or spoof signals. That’s why the approach described in this option is the strongest and most effective for protecting wireless gate systems.
