This weblog publish is a part of the “All You Have to Know About Purple Teaming” sequence by the IBM Safety Randori crew. The Randori platform combines assault floor administration (ASM) and steady automated purple teaming (CART) to enhance your safety posture.
“No battle plan survives contact with the enemy,” wrote navy theorist, Helmuth von Moltke, who believed in creating a sequence of choices for battle as a substitute of a single plan. Immediately, cybersecurity groups proceed to be taught this lesson the laborious approach. Based on an IBM Safety X-Power examine, the time to execute ransomware assaults dropped by 94% over the previous few years—with attackers transferring quicker. What beforehand took them months to realize, now takes mere days.
To close down vulnerabilities and enhance resiliency, organizations want to check their safety operations earlier than menace actors do. Purple crew operations are arguably top-of-the-line methods to take action.
What’s purple teaming?
Purple teaming may be outlined as the method of testing your cybersecurity effectiveness via the elimination of defender bias by making use of an adversarial lens to your group.
Purple teaming happens when moral hackers are licensed by your group to emulate actual attackers’ ways, methods and procedures (TTPs) in opposition to your personal techniques.
It’s a safety danger evaluation service that your group can use to proactively determine and remediate IT safety gaps and weaknesses.
A purple crew leverages assault simulation methodology. They simulate the actions of refined attackers (or superior persistent threats) to find out how effectively your group’s individuals, processes and applied sciences might resist an assault that goals to realize a selected goal.
Vulnerability assessments and penetration testing are two different safety testing companies designed to look into all identified vulnerabilities inside your community and check for methods to use them. In brief, vulnerability assessments and penetration assessments are helpful for figuring out technical flaws, whereas purple crew workout routines present actionable insights into the state of your general IT safety posture.
The significance of purple teaming
By conducting red-teaming workout routines, your group can see how effectively your defenses would face up to a real-world cyberattack.
As Eric McIntyre, VP of Product and Hacker Operations Middle for IBM Safety Randori, explains: “When you could have a purple crew exercise, you get to see the suggestions loop of how far an attacker goes to get in your community earlier than it begins triggering a few of your defenses. Or the place attackers discover holes in your defenses and the place you’ll be able to enhance the defenses that you’ve got.”
Advantages of purple teaming
An efficient approach to determine what’s and isn’t working in the case of controls, options and even personnel is to pit them in opposition to a devoted adversary.
Purple teaming presents a robust strategy to assess your group’s general cybersecurity efficiency. It offers you and different safety leaders a true-to-life evaluation of how safe your group is. Purple teaming may help your enterprise do the next:
- Determine and assess vulnerabilities
- Consider safety investments
- Check menace detection and response capabilities
- Encourage a tradition of steady enchancment
- Put together for unknown safety dangers
- Keep one step forward of attackers
Penetration testing vs. purple teaming
Purple teaming and penetration testing (typically known as pen testing) are phrases which are typically used interchangeably however are utterly totally different.
The principle goal of penetration assessments is to determine exploitable vulnerabilities and achieve entry to a system. However, in a red-team train, the objective is to entry particular techniques or knowledge by emulating a real-world adversary and utilizing ways and methods all through the assault chain, together with privilege escalation and exfiltration.
The next desk marks different practical variations between pen testing and purple teaming:
| Penetration testing | Purple teaming | |
| Goal | Determine exploitable vulnerabilities and achieve entry to a system. | Entry particular techniques or knowledge by emulating a real-world adversary. |
| Timeframe | Quick: In the future to a couple weeks. | Longer: A number of weeks to greater than a month. |
| Toolset | Commercially out there pen-testing instruments. | Broad number of instruments, ways and methods, together with customized instruments and beforehand unknown exploits. |
| Consciousness | Defenders know a pen check is going down. | Defenders are unaware a purple crew train is underway. |
| Vulnerabilities | Recognized vulnerabilities. | Recognized and unknown vulnerabilities. |
| Scope | Check targets are slender and pre-defined, akin to whether or not a firewall configuration is efficient or not. | Check targets can cross a number of domains, akin to exfiltrating delicate knowledge. |
| Testing | Safety system is examined independently in a pen check. | Methods focused concurrently in a purple crew train. |
| Submit-breach exercise | Pen testers don’t have interaction in post-breach exercise. | Purple teamers have interaction in post-breach exercise. |
| Objective | Compromise a corporation’s surroundings. | Act like actual attackers and exfiltrate knowledge to launch additional assaults. |
| Outcomes | Determine exploitable vulnerabilities and supply technical suggestions. | Consider general cybersecurity posture and supply suggestions for enchancment. |

Distinction between purple groups, blue groups and purple groups
Purple groups are offensive safety professionals that check a corporation’s safety by mimicking the instruments and methods utilized by real-world attackers. The purple crew makes an attempt to bypass the blue crew’s defenses whereas avoiding detection.
Blue groups are inside IT safety groups that defend a corporation from attackers, together with purple teamers, and are always working to enhance their group’s cybersecurity. Their on a regular basis duties embrace monitoring techniques for indicators of intrusion, investigating alerts and responding to incidents.
Purple groups usually are not truly groups in any respect, however moderately a cooperative mindset that exists between purple teamers and blue teamers. Whereas each purple crew and blue crew members work to enhance their group’s safety, they don’t all the time share their insights with each other. The position of the purple crew is to encourage environment friendly communication and collaboration between the 2 groups to permit for the continual enchancment of each groups and the group’s cybersecurity.
Instruments and methods in red-teaming engagements
Purple groups will attempt to use the identical instruments and methods employed by real-world attackers. Nonetheless, not like cybercriminals, purple teamers don’t trigger precise injury. As an alternative, they expose cracks in a corporation’s safety measures.
Some widespread red-teaming instruments and methods embrace the next:
- Social engineering: Makes use of ways like phishing, smishing and vishing to acquire delicate info or achieve entry to company techniques from unsuspecting staff.
- Bodily safety testing: Exams a corporation’s bodily safety controls, together with surveillance techniques and alarms.
- Software penetration testing: Exams net apps to search out safety points arising from coding errors like SQL injection vulnerabilities.
- Community sniffing: Screens community visitors for details about an surroundings, like configuration particulars and person credentials.
- Tainting shared content material: Provides content material to a community drive or one other shared storage location that incorporates malware applications or exploits code. When opened by an unsuspecting person, the malicious a part of the content material executes, probably permitting the attacker to maneuver laterally.
- Brute forcing credentials: Systematically guesses passwords, for instance, by attempting credentials from breach dumps or lists of generally used passwords.
Steady automated purple teaming (CART) is a sport changer
Purple teaming is a core driver of resilience, however it might probably additionally pose severe challenges to safety groups. Two of the most important challenges are the fee and size of time it takes to conduct a red-team train. Because of this, at a typical group, red-team engagements are likely to occur periodically at finest, which solely offers perception into your group’s cybersecurity at one time limit. The issue is that your safety posture is likely to be robust on the time of testing, however it might not stay that approach.
Conducting steady, automated testing in real-time is the one strategy to really perceive your group from an attacker’s perspective.
