我國《刑法》上規定的正當防衛既是我們一項合法權利，也是我們為國家和社會應盡的法律義務，是光榮的行為，受法律保護。

The justifiable defense stipulated in the criminal law is not only a legitimate right, but also a legal obligation for our country and society. It is a glorious act and protected by law.

我們在保安工作中，當遇到公共利益、本人或其他人的合法權益受到了不法侵害時，就可以正當防衛為武器，排除不法侵害，確保我們單位和他人的合法權益不受侵犯，從而有效地保護國家、集體和人民的利益，盡到我們應盡的職責。

We in the security work, when the public interest, I or other people's legitimate rights and interests of the illegal violation, can defend as a weapon to exclude illegal infringement, to ensure that our units and other people's legitimate rights and interests are not violated, so as to effectively protect national, collective and the interests of the people, we should try to duty.

2、正當防衛能夠起到預防違法犯罪，保證社會安定的作用。

2, justifiable defense can play a role in preventing illegal crimes and ensuring social stability.

根據正當防衛的規定，任何公民在正當防衛過程中，依法對不法侵害者本人造成人身或財產的損害，不負法律責任。這樣就使那些圖謀不軌或膽敢以身試法的分子，感到恐懼，有所震懾，使其不敢或輕易地進行危害社會的活動，從而起到了預防和減少違法犯罪的作用。
