Red and Blue team: What exactly are they doing!

Introduction

In this post, you will learn what is red, blue and purple teams. If you have read the cybersecurity book at least once you should have come across the Red and Blue Team and maybe the purple team as well. In this post, I will give a clear definition of all three teams and I will explain them in detail.

Red Team

A group of people doing penetration attacks, vulnerability testing, and all other cyberattacks legally in an organisation or company are called Red Team.

The general work given to Red Team is to do cyberattacks on their own company systems. Many companies don’t have the Red team or the blue team. The companies just hire an Ethical hacker, that’s it. In today’s world, it is very much necessary to hire a Red Team member.

You may argue hiring an Ethical hacker is enough? But if you asked cyber experts, they say “if a company hire an Ethical Hacker, what reason the hire him for” Can the hiring person can do every works. Absolutely not.

So, In recent times you could see the job availability for the red team separately. Hiring a red team member can strong the companies cybersecurity defence strategies.

The red team members do all kinds of cyberattacks and mainly the popular malware attack at the time and most commonly the Red Team perform attacks such as;

  1. Phishing, Malware Attack
  2. Social Engineering Attack.
  3. Targeted Attack.
  4. Crypto and Ransomware Attack.
  5. Penetration and Vulnerability etc.,

In addition, the Red Team members do some Internal reconnaissance attacks using hacking tools such as;

  1. Nmap
  2. ZMap
  3. Metasploit
  4. John the ripper
  5. THC Hydra
  6. Wireshark
  7. Aircrack – ng
  8. Kismet
  9. Nikto
  10. Cain and Abel

what will happen if the Red Team does these attacks;

Once the Red Team does the cyberattack on the organisation network and they would definitely find some loopholes and this vulnerability will be sent to the Blue team and they should patch the vulnerability.

Blue Team

A group of people defending cyberattacks and monitoring the systems on regular basis are called Blue Team. The Blue Team gets the vulnerability reports from the Red Team and the Blue Team members should think of a defence strategy for the vulnerability and execute the strategies.

The Blue Team defence strategies such as;

  1. Continueous monitoring network, system, device.
  2. Continueously collecting their organisation/company Network data and save it.
  3. Analysie the collected data.

After the above measures, the blue team should able to know what is the vulnerability and what measure to take at that place.

The Blueteam members also do some extra works such as;

  1. Check the firewall rules and if there is proble they can detect or replace it.
  2. Ensuing the softwares are up-to-date.
  3. Check the IDS and IPS sensors, if there is any problem they should detect them and also they should do continuous monitoring.
  4. Conducting a DDoS Attack.

In Addition, The Blue Team should also ensure other employees in the company are having knowledge about the new social engineering and phishing attacks.

If the company employees are not clear or don’t know about the new cyberattacks and phishing attacks the Blue Team should go and give them a lecture on the new cyberattack.

Purple Team

A group of people who intermediates between the Red and Blue Team. In other words, I can say a group of people from Red and Blue Teams have formed a purple team. The Red Team members will not share the secrete of how they did the cyber attack and the Blue Team will not share how they increased the cybersecurity strategies. So, the purple teams enter and gather the information from Red Team and give a report to the Blue Team.
