Final answer:
PDA security countermeasures include installing a firewall, disabling HotSync and ActiveSync features when not in use, and installing anti-virus software to prevent unauthorized access and malware infections.
Step-by-step explanation:
PDA security countermeasures are crucial for protecting personal digital assistants (PDAs) from various security threats. Some effective countermeasures include:
- Installing a firewall: This can help protect the PDA from unauthorized access and cyber attacks.
- Disabling HotSync and ActiveSync features not in use: This minimizes the risk of unauthorized data transfer and potential vulnerabilities.
- Installing anti-virus software: Just like computers, PDAs can benefit from anti-virus software to prevent malware infections.
These actions can significantly improve the security of a PDA and protect sensitive information stored within the device.
