As firewalls ease and multi-layered security systems are introduced, white hat hackers are expected to play a crucial role in identifying system vulnerabilities in advance and aiding in their remediation. White hat services like penetration testing and red team services are anticipated to become essential tools for strengthening security in public institutions.

Offensive Security
A security strategy for identifying system vulnerabilities from an attacker's perspective and preemptively recognizing potential threats through simulated hacking. This is mainly evaluated and reinforced in real-life-like situations such as penetration tests, red team activities, and mock attack scenarios.

Penetration Testing

The goal of penetration testing is to detect security vulnerabilities and attempt attacks to confirm actual threats. This testing tries to attack through paths interconnected by various vulnerabilities and is characterized by minimizing the issue of false positives that may arise from security vulnerability diagnostic solutions.

• Scope: Penetration testing is conducted on predefined systems, networks, applications, etc., analyzing and attacking environments with various security vulnerabilities like a real hacker would.

• Short-term: Penetration testing usually occurs over a set period, after which a result report is provided along with proposed vulnerability remediation plans.

• Technical Focus: Penetration testing is primarily focused on identifying technical vulnerabilities and misconfigurations, providing a practical report for strengthening a specific system's security.

Red Teaming

Red teaming aims to test the overall security posture of an organization and evaluate its defensive capabilities through practical cyber-attack scenarios. The red team emulates various tactics, techniques, and procedures (TTPs) used by real attackers to test the organization's security framework.

• Scope: Attacks are attempted on the entire organization and can exceed predefined boundaries. The goal is to assess the organization's overall defensive capabilities rather than focusing on a specific system.

• Persistence: Red team engagements are usually long-term and ongoing. The timing or nature of the attacks is not disclosed to the organization, testing whether the defense team (blue team) can detect and respond to the attacks in real time.

• Comprehensive Evaluation: Red teams explore not only technical vulnerabilities but also physical security, human factors (social engineering attacks), and gaps in procedures and policies. The defense team's (blue team) response capabilities are also evaluated.
