Effectively responding to such sophisticated supply chain attacks requires more than just a defensive approach. Sometimes, it's necessary to think from the attacker's perspective. This means understanding how attackers might infiltrate and exploit the system. By doing so, we can anticipate and respond to which points in the supply chain they are likely to target and how they might infiltrate them in advance.

In the future, for corporate and organizational security, it will be essential to think from the attacker's point of view and understand how they can infiltrate and exploit the system. To this end, an approach that acts like an actual attacker is necessary, such as finding vulnerabilities in a corporate system through Penetration Testing. Penetration testing allows for a realistic assessment of an organization's security state by simulating various paths attackers might take.

Scenario-based supply chain attack training is also important. This training aims to practice how the internal security team can respond based on actual supply chain attack scenarios. Teams that are trained this way can respond more quickly and accurately in real attack situations. Just as a soccer team formulates strategies in pre-matches, it involves being well-prepared before the real deal.

Email APT (Advanced Persistent Threat) training cannot be overlooked. APT attacks often start with highly sophisticated phishing emails. Regular training exercises for internal staff to identify and respond to APT emails can neutralize attackers' initial attempts, no matter how cunningly they disguise their emails.

Software supply chain attacks are not just a single enterprise's problem. They are severe threats that can significantly impact all organizations using the software. Although protecting a complex, multi-layered supply chain perfectly is challenging, thinking and responding from an attacker's perspective can be the solution. By understanding the attackers and anticipating the points they are likely to target, a more robust and practical security system can be established.

There is a saying, 'The proof of the pudding is in the eating.' Similarly, in Eastern culture, we say '百聞不如一見, seeing once is better than hearing a hundred times.' The same holds true for security. Directly experiencing and experimenting is the way to truly grasp its value. Ultimately, we must stay one step ahead in this battle. When attackers come, we should already be waiting for them.
