Businesses today need to implement layered defenses to prevent malware and ransomware from being installed on their networks. A web filtering solution should be one of those defenses. At its most basic, a web filter will block access to websites known to contain malware, exploit kits, or be used for phishing.
While web filters are commonly used as an additional security measure to block malware, one of the most important reasons for implementing a web filter is to prevent employees from accessing inappropriate or illegal website content and to prevent productivity draining online activities. In some cases, employers choose to severely restrict Internet access by only allowing employees to access to whitelisted sites – websites that need to be accessed for work purposes.
Regardless of the level of control you want to apply, it is usual for different controls to be needed for different individuals or groups of employees. For example, social media sites could be blocked for the entire organizations, but not for the marketing department, which would need to access corporate social media accounts.
While it is possible to place restrictions on different computers using a virtual local area network (VLAN), using a VLAN for content control lacks flexibility. If a device is on a VLAN that prohibits Internet access entirely, there may be instances when Internet access is temporarily required.
Integrating a Web Filter with LDAP
A better, more flexible solution is to base content filtering controls on the user, or user group. Integrating a web filter with LDAP allows filtering controls to be easily applied for different users, rather than limiting controls to a particular device.
In a call center, a telemarketer could logon using their LDAP information and have one set of filtering controls, whereas a manager could logon to the same device and have far greater permissions. The use of LDAP also allows detailed reports to be generated on which users and devices have accessed certain websites or website content. If DHCP is used on workstation and mobile devices, it may only be possible to view access logs up to a day old. Integrating a web filter with LDAP will make it much easier to generate reports when performing audits of Internet use.
Oftentimes, employees will be assigned to more than one LDAP group, so while it is possible to assign web filtering controls to specific groups, rules can be set to cater for members of more than one group, such as using the most or least restrictive content filtering settings when a user is in multiple LDAP groups. Not everyone will have a LDAP account. When guests require Internet access, a default configuration can be set. If users need to take their devices off site, content filtering by IP address or VLAN would not be possible. In such cases, a client-based solution is used to capture the LDAP session. This is important for K12 Schools that issue laptops for students to take home.
Using a web filtering solution that integrates with LDAP makes content filtering much easier to manage. WebTitan integrates with LDAP allowing you to easily apply content filtering controls by user or user group, with a range of APIs also provided to integrate with Active Directory, NetIQ and other deployment, billing and management tools.
