Network traffic monitoring from your site is vital. What is HTTPS inspection?
What Is HTTPS Inspection?
Web Filtering is the practice of monitoring and controlling the flow of network traffic entering an organization. HTTPS traffic is encrypted, making it challenging for traditional firewalls to monitor and control. Also, it is the capability to decrypt HTTPS traffic, read the content, and re-encrypt it before sending it on to its destination.
In a nutshell: Web Filtering monitors and controls traffic from users’ web browsers to block or allow access to different websites. Web Filtering allows organizations to secure their networks from malware and other types of malicious content. This includes controlling bandwidth usage by limiting access to bandwidth-intensive sites.
Monitoring employee productivity by blocking social media during work hours is vital as well. So, Web Filtering is designed to be transparent to the user so that they are unaware that filtering is taking place. This works by intercepting the network traffic flowing between a user’s web browser and the target website.
Decrypting HTTPS Traffic
With HTTPS Inspection, this interception process includes decrypting HTTPS traffic. So that the filtering device can analyze the text of the web page being accessed. This is to decide whether that page should be allowed or blocked.
Web Filtering is utilized by companies with multiple locations to allow a consistent policy for all users accessing the internet from any location. Without web filtering, each branch office would need its local internet connection with a firewall installed at each site. Because each location typically has its own IT staff and network architecture.
Using Web Filtering saves money because it can be managed centrally instead of through multiple connections at each branch office. Web filtering software typically includes many different levels of filtering which allow an organization to tailor its policy to its unique needs. Examples of these levels include:
1. a basic level that only blocks or allows access based on the URL being requested;
2. an intermediate level that adds categories such as file sharing sites or online games;
3. an expert level which provides much more customization based on keywords or specific domains
4. custom policies where every URL is specifically allowed or denied for individual users or groups
Web Filtering Services
Web Filtering can be implemented on-premises or in the cloud. HTTPS Inspection is a feature of web filtering services that inspects HTTPS traffic to allow or block web pages. This is based on the content being accessed by users.
Network traffic monitoring from your site is vital. Also, Web Filtering is the practice of monitoring and controlling network traffic entering an organization. Web filtering can be implemented on-premises or in the cloud.
Because it can be used by attackers to steal your login credentials or personal information like your credit card number. Clickjacking occurs when an attacker uses a hidden iframe or invisible button to trick you into clicking on a button or link. So, this is on a legitimate site to redirect your browser to a malicious website that can steal your login credentials or personal information.
The key role of HTTPS inspection in preventing these types of attacks is its ability to decrypt SSL traffic. Thus, inspecting it for indicators of malicious activity such as suspicious URLs and email addresses.
