Personal security refers to the measures individuals take to protect themselves from harm, theft, or other threats. This can include being aware of one's surroundings, using safety devices like alarms or locks, and practicing self-defense techniques. Personal security also involves safeguarding personal information to prevent identity theft and fraud. In today's digital age, personal security extends to online activities as well. Individuals should use strong passwords, enable two-factor authentication, and be cautious about sharing personal details on social media. By taking these precautions, people can enhance their safety and reduce the risk of becoming victims of crime or cyber threats.
