The terms ‘red team’ and ‘blue team’ are used to refer to cyber warfare as a weapon to test assertiveness towards planned attacks by skilled attackers. Testing infrastructure and personnel are becoming popular in government, finance, private enterprises, and many other institutions that largely focus on security. The red team stands as an external entity that is hired to test the effectiveness of a blue team. Blue team members are internal security staff who try to defend attacks that a red team executes. The main objective of this team activity is to test and strengthen the cybersecurity infrastructure of an organization.
Blue Team Vs. Red Team:
How is a blue team different from a red team?
A blue team, on the one hand, is similar to a red team as it assesses network security and identifies potential vulnerabilities. A blue team stands prepared to defend, modify and re-group defense mechanisms that contribute to the effectiveness of the incident response strategy.
Similar to that of a red team, the blue team must be aware of malicious activities, procedures, and techniques to construct response strategies for the organization. They are involved in strengthening the entire security infrastructure. A blue team also uses software like an intrusion detection system to analyze suspicious activity.
Blue team skills – To build a perfect defensive team
1. Be organized and detail-oriented
A blue team member is someone who follows the pre-defined methodologies that are tried and tested. A member should have an eye for detail, to prevent forming gaps in an organization’s security infrastructure.
2. Draft a threat profile
A threat profile is needed to assess the security of an organization. A good threat profile includes examples of real-life threat instances and potential threat attackers. The profile shall define working on weak fronts, to prepare for future attacks thoroughly.
3. Use hardening techniques
The hardening of DNS is usually ignored in hardening policies. Technical hardening techniques of all systems, including DNS hardening, is crucial as it reduces the exploit from attack surface hackers.
4. Know their detection systems
Software applications allow tracking of the network for any unfamiliar, or malicious activity. A blue team member should know network traffic, firewalls, packet filtering, etc. which enables better hold of the process in the organization’s systems.
5. Perform Security Information and Event Management
SIEM performs real-time analysis of security events. Security Information and Event Management collects data from external sources to analyze a specific criterion.
When it comes to the red team or a blue team, an organization cannot favor one team over another. A capable security infrastructure can be built only on the performance of the two teams. Engaging both sides to work together is the need for a perfect cybersecurity policy. Both the team members should be proficient with penetration testing in its two forms – defense and attack. The team members certified in penetration testing will be skilled in the process. But as the overall team activity is that of cyber warfare nature, the team members should be competent to challenge their roles. A successful team play, therefore, requires experts in penetration testing who can successfully penetrate a network.
EC-Council’s Licensed Penetration Testing (L|PT) Master is a certification that differentiates novices from experts in penetration testing. The 18 hours long program challenges three levels, where each level requires you to demonstrate mastery of deploying advanced penetration testing tools and techniques. The exam includes multi-level pivoting, SSH tunneling, OS vulnerabilities, privilege escalation, web server exploitation, web application exploits, etc. The candidates have to face the attacks in real-life scenarios on hardened machines, networks, and applications. L|PT Master tests your perseverance and focus by making you out-perform with every new challenge.
