Importance of Remote Vendor Access Controls

Neglecting to treat Remote Vendor Access™ (RVA) differently from traditional remote access for employees can introduce security risks ranging from virus infection to unauthorized access and non-compliance. The mission critical differences between employee remote access and RVA are significant.

Remote vendors should have access restricted so they are only able to access the areas of the company they support. A remote vendor contracted to administer specific Unix systems should not be connecting to other systems or resources at will.
Remote vendors use their own client equipment to establish connectivity. This means that requirements around Personal Firewalls, Anti-Virus, platforms, etc. are difficult if not impossible to enforce.
Requiring remote vendors to utilized specific VPN client software to access remotely may not be possible and can introduce remote vendor system liabilities and/or create incompatibilities with existing vendor client software.
Remote vendors have staff that is outside the view of the company. Staff changes at the vendor company may result in challenges around accountability.

Compliance Drivers

While these differences alone seem significant enough, the introduction of additional laws and regulations has added significantly to the list of RVA issues:

If the company is to be compliant with the Gramm Leach Bliley Act (GLBA), how does the company know that the vendor has not violated customer privacy while performing their service?

Similarly, under the Health Insurance Portability and Accountability Act (HIPAA), can the company ensure no patient data has been compromised? Specific to the Sarbanes Oxley Act, can the vendor directly or indirectly affect financial systems?

Remote Vendor Access Deserves Distinct Requirements

Since the areas most often supported by remote vendors include: system management, desktop management, application management, development, and security, the above mentioned questions are extremely difficult to address. Therefore, we submit that RVA necessitates a new set of remote access requirements distinct from those belonging to traditional employees:

The solution must provide granular access control, to completely control the access of the remote vendor.
The solution must be clientless, since most companies can not dictate the remote client system or software.
The solution must provide a complete and robust session and access audit trail, so companies can answer the regulatory questions of who had access and what did they do.
The solution must provide protection to the customer network from network pathogens like worms and malware.

A Solution that Meets the Challenge

An appliance based solution exists today that satisfies all of the above requirements. Recognizing the unique demands driven by Remote Vendor Access, eGuardPost™ was developed.

eGuardPost provides granular access control, not only to the system, but also to the protocol and userid used by the remote vendor. Multiple grouping functions make this scalable for thousands of systems.

eGuardPost provides a clientless solution. The only requirement for the client is a browser that supports Java.

eGuardPost captures and records the entire session in a space efficient manner, much like a keystroke logging mechanism works for a terminal. Since the entire session is captured, this solution works for Windows systems, Unix systems, applications and network equipment.

eGuardPost proxies the connection between the remote vendor and the customer system, meaning that no system level connection exists. Even if the remote vendor is completely compromised, there is no chance for that system to introduce malware into the customer network. The remote vendor connection to eGuardPost is HTTPS and SSH, eliminating the ability to pass netbios or other network traffic.

eGuardPost saves hours of event log review while providing 100% accuracy when looking at past events. For example, a single remote vendor patch load can create many thousands of system event logs. It could take hours or days of detailed log review to conclude an authorized patch was loaded. With eGuardPost session capture, a simple reply in minutes shows the patch command which was executed.

In addition, eGuardPost supports two factor authentication tokens, has High Availability capabilities, and is delivered as a purpose built appliance hardened with a commercial grade embedded firewall and AES encryption.
