How to Do it Yourself: Use Enhanced Filtering and Protection

Protect Your Business with Enhanced Filtering and Advanced Threat Protection

Blocking unapproved websites and email attachments with advanced filtering is crucial for protecting your business from cyber threats. This guide will walk you through setting up enhanced filtering and protection, aligning with CIS Control 9.4 (Limitation and Control of Network Ports, Protocols, and Services).

Step 1: Choose a Filtering Solution

Select a tool to implement enhanced filtering and protection, such as Microsoft Defender for Endpoint or Office 365 Advanced Threat Protection (included in Microsoft 365) or third-party solutions like Cisco Umbrella, DNSFilter, or Cloudflare.

Step 2: Configure Web Filtering

Set up web filtering to block unapproved websites. Define and implement web filtering policies to block malicious or unapproved sites and use category-based blocking to restrict access to specific types of websites (e.g., gambling, social media).

Step 3: Configure Email Filtering

Set up email filtering to block malicious attachments and phishing attempts. Define and implement email security policies to filter and block harmful emails and configure attachment filtering to block dangerous file types (e.g., executable files).

Step 4: Enable Advanced Threat Protection

Enhance your filtering solution with advanced threat protection features. Enable real-time scanning of web traffic and email content and use behavioral analysis to detect and block suspicious activities.

Step 5: Monitor and Adjust Filtering Policies

Regularly review and adjust filtering policies based on emerging threats. Use threat intelligence feeds to stay informed about new threats and regularly update filtering policies to address evolving security needs.

Why Enhanced Filtering and Protection Matter

Enhanced filtering and protection help prevent malware infections, phishing attacks, and access to harmful websites, thereby safeguarding your business. By implementing these measures, you can significantly reduce the risk of cyber incidents and protect your sensitive data.

This step aligns with CIS Control 9.4: Limitation and Control of Network Ports, Protocols, and Services, which focuses on controlling and filtering network traffic to reduce vulnerabilities.

By following these steps, you can set up effective filtering and protection, enhancing your business's security posture. Stay tuned for more tips on managing your business's cybersecurity risk effectively.
