An introduction to Managed Detection and Response

Security - Computer security


Businesses of all sizes and industries need to be prepared for any situation. 58% of Australian businesses experienced up to five IT security incidents in the last in the last year, with 37% of those incidents most likely concerning compromised endpoints.

With the chance of a cyber security incident occurring in your business environment all too likely, it’s time to take a look at active security defences. Crucially, this means being alert and ready to take action in the event of a cyber-attack – or, preferably, proactively staving off attacks before they exploit your endpoints. 

Managed threat response is the dynamic solution your business needs for extended detection and response to catch cyber-attackers before they strike.

What is Managed Threat Detection and Response?

Managed Threat Detection and Response (MDR) is a service that proactively identifies, mitigates, and responds to threats before they affect your business’ resources or data. It requires you to consider the risks posed by various threats and malware prior to implementing security policies or technologies. 

This service provides customers with remotely delivered modern security operations centre functions, which allow businesses to rapidly detect, investigate, and actively respond to threats. 

Managed threat detection and response service providers offer a turnkey experience by using predefined technology stack (including endpoint, network, and cloud services) to collect relevant data, logs, and contextual information, which is then analysed on the provider’s platform using various methods. 

Benefits of MDR

MDR is an effective way for small and medium-sized businesses (SMB) to defend themselves from cyber-attacks. It provides all the services required to respond to a cyber incident, including prevention, detection, and remediation.

Fast action: When an incident is confirmed, a dedicated threat response lead is provided to directly collaborate with your on-premises resources (internal team or external partner) until the active threat is neutralised.

Reduced costs: Avoid the cost of hiring specialised staff for detection and prevention.

Improved productivity: Focus on their core business instead of being distracted by security issues.

Increased understanding of risk: Understanding the risk posed by different threats allow you to adjust your cyber security posture to mitigate those risks.

24/7 monitoring: Constant endpoint monitoring and management by skilled security analysts.

Expert investigation: Incidents are investigated by an expert team to understand what caused the initial alert, and how to remedy it.

Improved threat intelligence: Better response based on indicators from global insights.

Common cyber threats

A number of threats may affect your network that are not easily detected by traditional means, including: 

Zero-days: a flaw in software that allows an attacker to take control of the system without any warning or protection.

Ransomware: a malicious computer program that takes over a device or network of devices and demands a ransom to be paid in order to regain control.

Software exploits: a type of security exploit that take advantage of vulnerabilities in computer software to cause unintended or unanticipated behaviour to occur on computer systems.

Anomalous/suspicious behaviour: a term used in cyber security to describe any activity that is different from what is expected. It can be anything from an unusual change in network traffic, to a user logging into the system and doing something they would not normally do.

Conducting threat hunts

Rather than simply waiting for threats to strike, security analysts regularly conduct threat hunts, where they proactively hunt for, and validate, potential threats, and incidents. Threat hunting also identifies new Indicators of Attack (IoA).

Threat hunters collect the required contextual information from targeted devices and third-party sources, perform their initial hunts, and take the necessary steps to eliminate a detected threat, or improve their hypothesis to reduce “false positive” detections.

This proactive security posture not only helps mitigate cyber-attacks, it identifies weaknesses before they are taken advantage of, strengthening the business’ overall cyber security posture.

Control and transparency

A significant portion of the benefits of MDR comes from the transparency that it provides to the user. With MDR, you can better understand how your assets are being used and where risks are occurring. This type of visibility can help you proactively address risks, detect trends that may indicate a need for tighter controls, and take corrective actions when necessary.

Increased transparency in your business helps you identify issues and find solutions. The information that comes back to you from your managed threat response team can help guide and position you to identify and address the root causes of issues. This will help you avoid common problems and tedious workarounds that can slow down or stop your business.

Proactive defence

One of the biggest benefits of MDR is its ability to proactively detect and respond to threats. With this capability, you can take steps to protect yourself by implementing controls before they are needed. It can provide a continuous, automated, and secure way to protects your assets. 

You can ensure that devices and applications are updated to ensure the latest versions of security patches are in place. This is particularly useful when devices and applications that need to be updated are located in remote locations or behind firewalls.
