Open XDR Services Are Helping Cybersecurity Teams

Benefits of Implementing an Open XDR

Open XDR solutions are designed to perform various activities that include:

• - Threat detection
• - Threat hunting
• - Threat response
• - Threat investigation

These activities provide benefits to your organisation, and here we mention five of the benefits of using an Open XDR-as-service.

1. It centralises your log data and reduces the time security experts spend collecting data from numerous sources

2. Helps you achieve faster reaction times to threats through streamlined detection and response capabilities

3. Allows for scalability as your organisation grows when you require enhanced security tools and technologies

4. Saves your organisation time and money to free up more resources for profit-making activities

5. Reduces the number of false positives through constant optimisation of your security tools

So, is it necessary for you to implement an Open XDR strategy?

How Open XDR Supports SIEM

SIEM is used to collect alert logs and ensure compliance, data storage and analysis. It combines security information management (SIM) and security event management (SEM). The main functions of SIEM include:

• - Collecting log data on incidents and alerts
• - Using the data to identify, categorise and analyse the events and incidents logged
• - Examining your entire threat environment, including cloud applications and hardware
• - Collating all security data into a centralised security platform
• - Providing visibility into destructive hacker behaviour
• - Taking advantage of log data to create alerts and reports and ensure an efficient incident response
• - Preempting security threats before they cause damage to your organisation’s security systems

SIEM is focused on log collection, compliance data storage, analysis and reporting alerts. However, it cannot adequately identify threats unless connected to a separate security system. Open XDR can adequately fill this gap and support SIEM by providing threat-based use cases.

How Open XDR Supports SOAR

SOAR often works alongside SIEM, but this lateral connection is the only integration mechanism SOAR has. It cannot perform big data analytics or protect your network from breaches.

SOAR faces the challenge of integrating various siloed tools. It must be properly configured to work efficiently – a task that takes a lot of your employees’ time. A system failure may also disrupt or disconnect the data feeding into the system. This results in a large number of false positives and low-priority alerts.

XDR enhances SOAR by breaking down these siloes and integrating all your cybersecurity tools. It also provides:

• - Advanced analytics
• - Improved threat detection and response
• - Enhanced visibility of your network environment
• - Better scalability

XDR, however, should not fully replace SOAR as it cannot use playbooks to perform orchestration activities. It also can’t automate actions outside incident responses, meaning it cannot fully replace SOAR.

For this reason, it is advisable to hire a professional Open XDR vendor like Microminder to implement the correct XDR strategy to merge the two security tools.

How Open XDR Supports EDR

EDR uses behaviour analysis to identify threats at your endpoints and help you perform kill chain analysis. It provides greater network visibility and prevents unknown threats from infiltrating your systems. It also helps your team filter network traffic and automates rule-based event responses to ensure prompt remediation and mitigation of threats.

So how does XDR provide additional support to EDR?

1. EDR allows your organisation to manually integrate the tools with various third-party point solutions. The disadvantage of this, however, is that you will have to manage a range of different security tools.
   Open XDR security companies like Microminder provide an integrated solution that will simplify your security architecture. It will give your infosec teams greater visibility and threat management.
2. EDR is focused on providing wider visibility for a specific device. XDR, however, provides a wider view of your security architecture by integrating numerous threat areas. These areas include endpoints, email and cloud security, and by providing end-to-end tracing, you can easily manage security across various environments.

Four Questions to Ask Before Choosing the Right XDR Solution

1. Does the tool automate responses? An efficient Open XDR tool should be able to automate responses across domains to help prevent incidents. These responses should be repeatable and pre-defined, which allows infosec teams to intervene at any step of an ongoing attack.
2. Does the system provide advanced analytics? Open XDR should be able to send intelligence alerts to allow security teams to develop incident timelines. It should also include automated, AI-based event correlation.
3. Can the Open XDR architecture be integrated with our SIEM? Both systems contain TDIR (threat detection, investigation and response) capabilities. Open XDR focuses on threat detection across different security stacks.
   SIEM should be able to go beyond threat detection and response and also provide log event storage to help meet compliance requirements.
   Some organisations might need to start with a specific focus on TDIR, but they usually plan to scale their business.
   Such companies can choose first to install an Open XDR platform that can easily and seamlessly be upgraded to integrate with a SIEM. Look for XDR tools that offer a solution that can cater to both small-scale and advanced business security needs.
4. Does the Open XDR solution offer visibility across your entire security stack? An efficient Open XDR platform collects telemetry from numerous security layers, attack points and networks. It should:
   1. Provide constant monitoring and management of all incoming alerts
   2. Use threat intelligence activities to actively search for hidden threats
