Automated Attack Disruption: Improve Your Security with Microsoft Defender for Business

Updated: Oct 16

Cyberattacks have become a major threat, especially for small and medium-sized enterprises (SMEs). These businesses are more vulnerable than large corporations due to their limited resources. That's where the automated attack disruption technology offered by Microsoft Defender for Business  comes into play. This innovative security solution provides comprehensive protection to SMEs and allows business processes to continue uninterrupted.


Microsoft Defender for Business: Automated Attack Disruption

Microsoft Defender for Business is a user-friendly security solution designed specifically for SMBs. One of the most striking features of this system is its automatic attack interrupt capability. This feature is an industry first for Endpoint Detection and Response (EDR).


How Does Automatic Attack Interrupt Work?

Automated attack disruption responds to active human ransomware attacks in real time. Malicious attackers contain users and devices before they can perform more damaging actions. This capability is "on by default" for SMBs, allowing business to continue uninterrupted. For example, imagine that one day an employee's account is hacked. Automatic attack interrupt detects this attack immediately and neutralizes the account, preventing the attacker from doing further damage.


The Impact of Cyber Threats on SMBs

Cyber threats can be quite disruptive for SMBs. In 2021, the total cost of cybercrime to small businesses worldwide reached $2.4 billion. The rate of ransomware attacks targeting small businesses is as high as 82%. For example, "TeknoSoft", a small technology company, suffered a massive ransomware attack in 2021. The attackers encrypted all of the company's data, demanding a ransom of $100,000. If they had been using Microsoft Defender for Business, this attack could likely have been detected and prevented early.


Benefits of Automated Attack Disruption

Microsoft Defender for Business offers automatic attack disruption and provides several key benefits:

  1. High-reliability signals: Thanks to the high-reliability signals provided by the AI model, complex attacks are detected early.

  2. Auto-blocking: Ongoing attacks are automatically blocked, and compromised users and devices are protected.

  3. Limiting impact: Limiting the impact of an attack reduces lost productivity and associated costs.


How Does It Work?

Microsoft Defender for Business helps customers respond to ransomware attacks in real time with its Endpoint Detection and Response (EDR) capability. In this process, attackers are neutralized before they can carry out their malicious actions. For example, "SağlıkNet", an SME operating in the healthcare sector, used this solution to prevent an attacker from obtaining patients' personal and medical information.


Case Study

Let's take a look at a real-life example to better understand this system. Let's say an attacker gained access to user Bob's account with a compromised credential and tried to create backup credentials. Automatic attack interrupt kicks in and detects this activity and terminates the RDP session. Mert's account is taken under control and the attacker is prevented from taking further malicious steps.


If the attacker fails in the first step, they will try to use Mert's credentials for remote encryption. However, the system stops this attempt by preventing Mert's activity. Caught in the clutches of failure again, the attacker finally uses the backup credentials they created to encrypt remotely. However, the backup credentials are also automatically associated and the horizontal movement that is tried to occur is stopped. Happy ending!


Stay Safe with Microsoft Defender for Business

As a result, the automatic attack interruption feature offered by Microsoft Defender for Business offers a major advantage for SMBs. This innovative security solution provides effective protection against cyber threats, while at the same time helping businesses to keep their business running without interruption.


In this digital world where cyber threats are increasing day by day, stay safe with Microsoft Defender for Business!
