Around Mid-2010: A Secret Service agent advises Pagliano to take a step to improve the security of Clinton’s private server, but the step is not taken.

After Bryan Pagliano sets up Clinton’s new private server in January 2009, he sets up Internet Protocol (IP) filtering on the firewall, once a firewall is established in late March 2009. Pagliano will later tell the FBI that he tried to review the firewall log files once a month.

At some point, Justin Cooper, a Bill Clinton aide who is helping Pagliano manage the server, puts Pagliano in contact with a US Secret Service agent. The timing of this is not clear. However, in a September 2016 Congresssional hearing, Cooper will say it happened after Clinton’s server started to get frequent “brute force” hacking attacks, and that begins around the middle of 2010.

This agent recommends that Pagliano should also perform outbound filtering of email traffic. According to a September 2016 FBI report, “Pagliano further considered, but ultimately did not implement, a Virtual Private Network (VPN) or two-factor authentication to better secure administrative access to the server system by him and Cooper.”

The FBI report will explain: “‘VPN’ is a private network that runs on top of a larger network to provide access to shared network resources, which may or may not include the physical hard drives of individual computers… VPN offers an additional layer of security by encrypting the data traveling to the private network before sending it over the Internet. Data is then decrypted when it reaches the private network. … ‘Two-factor authentication’ is a method of confirming a user’s claimed identity by utilizing a combination of two different components…” (Federal Bureau of Investigation, 9/2/2016) (US Congress, 9/13/2016)

Around March 7, 2015: Changes are made to the security settings of Clinton’s private server after its existence was revealed in the media.

In the days following a New York Times article revealing Clinton’s use of her private server, Cheryl Mills, who is one of Clinton’s lawyers as well as her former chief of staff, requests that Platte River Networks (PRN), the computer company managing Clinton’s server, conduct a complete inventory of all equipment related to the server. Two unnamed PRN employees do so.

This results in some changes to the server’s security settings around March 7, 2015. According to a September 2016 FBI report, these changes “include disabling the server’s public-facing VPN page and switching from SSL protocol to TLS to increase security.”

The FBI will explain: “TLS is a protocol that ensures privacy between communicating applications, such as web browsing, email, and instant-messaging, with their users on the Internet. TLS ensures that no third-party eavesdrops on the two-way conummication. TLS is the successor to SSL and is considered more secure.” (Federal Bureau of Investigation, 9/2/2016)
