What is CRSP?

Microsoft Global Compromise Recovery Security Practice.

Who is CRSP?

We are a worldwide team of cybersecurity experts operating in most countries, across all organizations( public and private ), with deep expertise to fasten an environment post-security breach and to help you prevent a violate in the first place.

As a specialist team within the wider Microsoft cybersecurity functions, we predominantly focus on reactive security projects for our clients. The main types of projects we undertake are 😛 TAGEND

Compromise recovery: Giving customers back control of their environment after a compromise. Rapid ransomware recovery: Restore business-critical applications and restriction ransomware impact. Advanced threat hunting: Proactively hunt for the presence of advanced menace performers within an environment.

In addition to our reactive operate due to our technical expertise and experience, we are sometimes engaged to work proactively with high-profile customers to help keep them safe no matter who or what the adversary.

Compromise recovery is the process by which we withdraw existing nefarious attacker control from environmental issues and tactically increase security posture within a set period of time. Compromise recovery takes place post-security transgres. This remedial activity often follows investigation into the cases from our Microsoft DART colleagues or other third-party forensic incident response experts. We incorporate these findings into the recovery efforts and work to build your environment as fasten as we can, with the aim for “youre going to” can be taken control.

Rapid ransomware recovery is where an organization has been targeted by advanced ransomware, which is usually human-operated and targeted to specific organizations. We used to help bringing back operation-critical business systems, such as Azure Active Directory, and work hard to limit exposure of ransomware across an environment. These programmes are typically very time-sensitive and require a great number of efforts to contain the attack.

With advanced threat hunting, we bring expertise in Microsoft security tooling into an environment to actively hunt for advanced menace actors–advanced lingering threats( APTs) and decided human adversaries. We can work within a customer’s existing security processes to help improve internal security capabilities and trust. As part of this, we deliver our findings and provide practical and real the recommendations on how to further enhance your security, as well as indicate if additional tactical steps may be required.

Historically we have maintained our life quiet, and our activities were only published internally at Microsoft. Given that we are seeing more and more cybersecurity incidents, we thought it was time to publicly let the world know where we fit into the Microsoft security story.

We are flexible in our approach to helping clients. Traveling and being away from home for extended periods and working in high-pressure situations with high-profile issues is normal and frequent for a CRSP cybersecurity professional. We are likewise practiced and effective at delivering these participations altogether remotely.

CRSP is the team that takes back control.

How do we help customers?

At Microsoft, we advocate that everyone maintain an “assume breach” mindset. Unfortunately for the customers “were working with”, we know there has been a breach and often find the worst that attackers can do.

In the last year, we have dealt with issues from crypto-malware making an entire environment unavailable to a nation-state attacker maintaining covert administrative perseverance in an environment. We help customers take back control. At all times, we work with customers to restore legitimate control and secure trust in their computing environment by removing, mitigating, and reducing the risks.

Our scope is often to secure the assets which thing the most to organizations, such as Azure Active Directory, Exchange, and certificate authorities, whose loss leads to the highest impacts and therefore have the highest risks.

Part of our work is to deep analyze your existing investments and identity where activity is required. This investigation is helpful as it helps you understand your assets in a way you may have never had the opportunity to do so previously.

Bringing back control of these high-value assets is our goal. By taking a tactical approach we implement secure and sustainable changes that minimise exposure, thereby reducing the risk of any follow-up assaults and exhaustively removing any illegitimate control and hardening systems. We do this within a specific timeframe in mind which is usually measured in weeks. For a more urgent crisis, “were having” operated in hours.

We see sustainability in maintaining control as a key part of our role. This control is not simply removes the attacker but reduces the risk of follow-up assaults, so therefore it must be possible to maintain. We render deep technical expertise to attain your environment more secure. An additional benefit of working with CRSP is that we often leave our patrons with a true security administration mindset.

Based on assist so many patrons, we understand what works well to secure an environment and what doesn’t. Some things may be important but not strictly necessary for you to take back control. That isn’t to say that these things are not important in improving security, because they often are, but when it comes to tactical and swift activities, they may not be vital. As part of medium and longer-term planning, we help you identify these options correctly and build a plan to enable you to further continue your security journey.

Although we bring with us a squad who are experts in their own specialties, we never run alone. We work with our wider Microsoft colleagues and sometimes our partners and third parties to identify additional vulnerabilities and security incidents. We assist you and your security team in building sure they can help maintain your security once we leave.

Usually, our services are engaged through the regular customer services and support route or via your Microsoft account handling team.

We hope you should never need our services. But if you do, know you are in safe hands.

Fasten admin track

We have documented many times that most antagonists will go after your Azure Active Directory and your administrators because they know these will give them the best opportunity for having full control. Securing your administrative route will make it much harder for adversaries to take over.

Administrative workstations, credential hygiene, and implementing the tier model will help a great deal. Additionally, having security and administrative functions working together is something we encourage our customers to do.


Turn off unused services, implement host-based firewalls, run network-level encryption, remove unused software, maintain software up to date, remove unused accounts, check certification stores, and remember to do the same for any hypervisors or storage networks. You should reduce interdependent control and adopt in-depth defense with Zero Trust.

Patching cycles should be measured in hours and not weeks. Your business-critical applications should not be running on obsolete software, hardware, or firmware. Exploit and zero-days are bought in” the wild” within hours–sometimes even minutes, so it is essential to do the patching as quickly as possible. With this approach, you are limiting the attack surface significantly.

Insights and oversight matters

Understand what is normal in your environment and what isn’t. You can only do this with good monitoring and comprehensive baselines.

Know that monitoring isn’t just looking at traditional security incidents but looking at spotting exposure to your admin track. Monitor the performance of your systems and make sure they are logging correctly. Make sure that people who are looking at this data understand the difference between normal and not normal. These process may not always be in your security functionings, so it is key that you add this. Using AI can greatly improve your visibility in what should be normal user behavior, by creating alerts around these behaviors( with automatic mitigations) you are eligible to have a head start in protecting your infrastructure and referred components.

React quickly and efficiently to anything that is not normal or supposed bad.

Overall judgment

In the end, cybersecurity is largely about the mindset that needs to be adopted, embraced, and supported by everyone in an organization. You can lock all the doors, install an alarm, and set CCTV in place, but unless everyone remembers to lock the door and turn alarm systems on you won’t be very secure.
