Exercises between red and blue teams simulate attacks on company networks.

FREMONT, CA: Red teams are offensive security experts skilled at attacking systems and breaching defenses. Blue teams are defensive security specialists tasked with defending internal networks against all types of cyber attacks and threats. Red teams mimic assaults on blue teams to evaluate the network's security. These red and blue team activities give a comprehensive security approach that ensures strong defenses while also keeping an eye on new threats. The red team attacks the blue team's defenses and attempts to breach them. In an ideal world, these ethical hackers would be oblivious of an enterprise's protection measures, which is why their services are frequently outsourced. Red teams employ a range of tactics and technologies to exploit a network's weaknesses and vulnerabilities. It's critical to understand that red teams will use any methods required to breach the system following the conditions of engagement. Depending on the vulnerability, they may use malware to infect hosts or even overcome physical security barriers by cloning access cards.

The following are some examples of red team exercises:

• Penetration testing, also called ethical hacking, is when a tester attempts to acquire access to a system, frequently using software tools.
• The Red Team uses social engineering to convince or deceive staff members into exposing their credentials or granting entry to a restricted location.
• Phishing is the practice of sending seemingly valid emails to staff members that tempt them to perform specific actions, such as signing into the hacker's website and entering credentials.
• Software tools for intercepting communication, such as packet sniffers and protocol analyzers, can map a network or read plain text messages. These tools are used to gather information about the system. For instance, if an attacker is aware that a server is using Microsoft's operating system, they will concentrate their efforts on exploiting Microsoft vulnerabilities.
• Cloning a security card of an employee to get access to restricted places, such as a server room.

Along with these more conventional hacking approaches, red team members employ custom-built tools to gain access to networks and frequently increase privileges to penetrate the firm successfully. Since exercises improve security, red team members prepare post-attack reports that document the strategies utilized, the vectors targeted, and successful and unsuccessful attempts. Additionally, the reports should include recommendations for enhancing the organization's security posture, ensuring that defenses are up to date and hardening systems against potential attacks. The reports assist blue teams in determining where coverage gaps exist, where protections failed, and where security should be reinforced.
