Why is security necessary? Security is fundamentally an activity and action designed to ensure safety.
The tragedy that occurred in Itaewon on October 29, 2022, was truly heartbreaking.
The government belatedly added 'congestion and traffic guidance security services' to the scope of security services under the Security Services Act, and introduced measures to ensure safety in resolving congestion and traffic problems at various festivals and large-scale events.
But safety is not achieved through laws alone.
Each individual must become his or her own bodyguard, striving to protect the safety of himself or herself and his or her family through protective mindset and behavior.

Meanwhile, on July 31, 2024, Ismail Haniyeh, the top political leader of Palestinian Hamas, was killed by a remote-controlled explosion of a pre-planted explosive device at the Iranian guesthouse known as Neshat (the IRGC said the explosion was "a short-range projectile with a warhead of approximately 7 kg" from outside the residence).
The importance of basic information and security is just as great as the countermeasures against cutting-edge weapons.
Domestically, the Blue House, which had been used as the presidential office and residence for nearly 74 years since the establishment of the Republic of Korea government, returned to the people, and with the start of the Yoon Seok-yeol administration in 2022, there were changes such as the presidential office moving to Yongsan and the presidential residence moving to Hannam-dong.
Security must consider and devise methods to respond to the changing security environment in any situation.
Like a boat going against the current, you have to go forward step by step, fighting against the waves.

Before I knew it, the 8th revised edition of Introduction to Security Studies was published.
Just as I first began writing, with the intention of organizing my life's work, researching security crisis management systems and developing a systematic "security studies" based on them, even after publishing each revised edition, I always felt a lingering sense of regret in a corner of my heart.
I am glad that with the publication of this revised 8th edition, I feel that 『Introduction to Security Studies』 as a textbook has been completed to some extent, and the regret that I had felt has been relieved.
