For a secretary of state, running your own email server might be a clever—if controversial—way to keep your conversations hidden from journalists and their pesky Freedom of Information Act requests. But ask a few security experts, and the consensus is that it's not a very smart way to keep those conversations hidden from hackers. 
 
 On Monday, the New York Times revealed that former secretary of state and future presidential candidate Hillary Clinton used a private email account rather than her official State.gov email address while serving in the State Department. And this was no Gmail or Yahoo! Mail account: On Wednesday the AP reported that Clinton actually ran a private mail server in her home during her entire tenure leading the State Department, hosting her email at the domain Clintonemail.com. 
 
 Much of the criticism of that in-house email strategy has centered on its violation of the federal government's record-keeping and transparency rules. But as the controversy continues to swirl, the security community is focused on a different issue: the possibility that an unofficial, unprotected server held the communications of America's top foreign affairs official for four years, leaving all of it potentially vulnerable to state-sponsored hackers. 
 
 "Although the American people didn’t know about this, it’s almost certain that foreign intelligence agencies did, just as the NSA knows which Indian and Spanish officials use Gmail and Yahoo accounts," says Chris Soghoian, the lead technologist for the American Civil Liberties Union. "She’s not the first official to use private email and not the last. But there are serious security issue associated with these kinds of services...When you build your house outside the security fence, you’re on your own, and that’s what seems to have happened here." 
 
 The most obvious security issue with Clinton running her own email server, says Soghoian, is the lack of manpower overseeing it compared with the State Department's official email system. The federal agency's own IT security team monitors State Department servers for possible vulnerabilities and breaches, and those computers fall under the NSA's protection, too. Since 2008, for instance, the so-called Einstein project has functioned as an umbrella intrusion-detection system for more than a dozen federal agencies; Though it's run by the Department of Homeland Security, it uses NSA data and vulnerability-detection methods. 
 
 Clinton's email wouldn't have the benefit of any of that expensive government security. If she had hosted her email with Google or even Yahoo! or Microsoft, there might be an argument that those private companies' security teams are just as competent as the those of the feds. But instead, according to the Associated Press, Clinton ran her server from her own home. Any protection it had there—aside from the physical protection of the Secret Service—would have been limited to the Clintons' own personal resources. 
 
 A more specific threat to Clinton's private email relates to its domain name. Unlike the State Department's State.gov domain, Clinton's Clintonemail.com is currently registered with a private domain registrar, Network Solutions, as a simple Whois search reveals. The domain Clintonemail.com (and thus its registrar) was certainly known to at least one hacker: The notorious celebrity hacker Guccifer first revealed it in 2013 when he spilled the emails of Clinton associate Sydney Blumenthal. 
 
 Anyone who hacked Network Solutions would be able to quietly hijack the Clintonemail.com domain, intercepting, redirecting, and even spoofing email from Clinton's account. And Network Solutions is far from the Internet's hardest target: Hundreds of its domains were hacked in 2010, a year into Clinton's tenure at the head of the State Department. 
 
 Even if Clinton used the account only for personal messages rather than those of international importance (say, something along the lines of: "Let's go ahead and drop those bombs, Bibi") the notion that they could be both intercepted and spoofed through a common hacking vector is particularly troubling. "Even the most mundane of communications can be interesting to an intelligence service," says the ACLU's Soghoian. The NSA, he points out, thought it was worthwhile to monitor German Chancellor Angela Merkel's personal cell phone, for instance.1 
 
 There's no evidence, of course, that Clintonemail.com was ever actually compromised. University of Pennsylvania computer science professor Matt Blaze says judging its security versus the State Department's own email servers would require more information. But he notes that the control of the server's domain is a real issue. "It’s certainly true that the domain State.gov is probably harder to hijack than clintonemail.com," says Blaze. 
 
 To be fair, the State Department's track record for its own email security isn't exactly spotless, even relative to Clinton's DIY approach. Consider this: Some critics have pointed out in recent days that Clintonemail.com currently uses an invalid TLS certificate, another method that a man-in-the-middle might use to intercept or spoof emails from the server; but Stanford researcher Jonathan Mayer points out to WIRED that the State Department's own TLS certificate is currently invalid, too. Mayer believes that Clinton's bad certificate is a result of a misconfiguration that occurred when the email service was transferred in 2013 to the McAfee-owned company MX Logic. The State Department, Mayer says, uses a "self-signed certificate," a less-than-sterling security practice. "Against man-in-the middle attacks, both are currently insecure," he says. 
 
 In fact, the State Department has been the target of several successful hacker attacks over the past decade. The most recent one in November of 2014 forced the agency to temporarily shut down its email system as a response to concerns that unclassified communications had been breached by Russian hackers. 
 
 But at least, in that case, there was a response. If the same sort of highly resourced hackers had gone after the server in Clinton's basement, there's no guarantee that the same alarms would have gone off.

In fact, the source for Der Spiegel's reporting on that phone surveillance isn't publicly known. ||||| (CNN) Hillary Clinton broke her 48-hour silence over the use of her personal email account while she served as secretary of state with a late-night tweet Wednesday saying she wants "the public to see my email." But her response is unlikely to tamp down the pressure for answers as she faces the deepest scrutiny she's been under since leaving the government. "I asked State to release them," Clinton tweeted at 11:35 p.m. ET "They said they will review them for release as soon as possible." 
 
 The developments have escalated since the personal email account was first revealed Monday night, turning into both a political tug-of-war between Republicans and Democrats. The account raises questions -- even from within her party -- about transparency, security in the government and her future. 
 
 While the Clintons have plenty of allies, some on the left are using this opportunity as a sign to flag that the Democrats' front-runner in the 2016 campaign might still face some of the same organizational challenges and public relations gaffes her campaign had eight years ago. 
 
 As the story continues, here's a look at what you need to know. 
 
 Clinton: 'I want the public to see my email' 
 
 Late Wednesday night, Clinton made her first public comments regarding the use of a private email server as opposed to a State Department one. 
 
 I want the public to see my email. I asked State to release them. They said they will review them for release as soon as possible. — Hillary Clinton (@HillaryClinton) March 5, 2015 
 
 Marie Harf, a State Department spokeswoman, said the agency would review Clinton's request. 
 
 "The State Department will review for public release the emails provided by Secretary Clinton to the Department, using a normal process that guides such releases," Harf said. "We will undertake this review as quickly as possible; given the sheer volume of the document set, this review will take some time to complete." 
 
 A senior State Department official said on Thursday the department expects the review of Clinton's emails to "take several months." 
 
 Clinton tried to avoid the controversy. On Tuesday night the former secretary of state delivered a much-watched speech in Washington, but did not mention her emails, instead focusing on politics and teasing her likely presidential run. 
 
 After the State Department requested all secretaries of state send in their documents in 2014, Clinton and her team turned over 55,000 pages of emails to the State Department in December 2014. It is those emails that the former secretary of state wants released to the public. 
 
 But because the emails were housed on her private account, the process was overseen by Clinton and her aides, not archivists like it would have been if the email was housed on government servers. 
 
 A Clinton aide said that "anything that pertained to her work there" was given to State. 
 
 "So if she emailed with her daughter about flower arrangements for her wedding, that didn't go in," the aide said, "but if she emailed one of the 100 State Department officials she regularly corresponded with, State had it in their servers already and HRC's office replicated that to ensure it was all there." 
 
 The fact, though, that Clinton was in control of her own archives has concerned some archive and cybersecurity experts. 
 
 The issue has grown from one focused on Clinton to something the White House has had to answer to, as well. Josh Earnest, White House press secretary, said on Tuesday that the administration's policy "allows individuals to use their personal e-mail address as long as those e-mails are maintained and sent to the State Department, which if you ask Secretary Clinton's team, that's what they completed in the last month or two." 
 
 A senior White House official told CNN on Thursday that aides to the President have been in touch with Clinton's staff "to confirm facts and let them know what we planned to say." 
 
 Most, but not all, Democrats unite behind Clinton 
 
 Most Democrats don't want to talk about Clinton's email controversy. She is the party's prohibitive presidential favorite in 2016 and she leads every poll about the race, making it hard for other Democrats to draw her ire or knock her and risk hurting their party's best chance at keeping the White House. 
 
 When CNN's Ted Barrett tried to ask congressional Democrats about the controversy, the responses were far from eager 
 
 "I'm not up to speed on it. I'm really not," said Sen. Jon Tester of Montana, who runs the Senate Democrats' campaign committee. "Check back." 
 
 "I don't know enough about what those rules are, honestly, to comment," said North Dakota Sen. Heidi Heitkamp. 
 
 When CNN tried to ask Massachusetts Sen. Elizabeth Warren, who some liberals are hoping will challenge Clinton for the 2016 nomination, a staffer shielded her and deliberately blocked the senator from answering. Warren climbed into an elevator without looking up. 
 
 Clinton supporters have vocally supported her. New York Rep. Steve Israel said, "Pretty soon we'll have a special investigative committee for every action that Hillary Clinton takes. There will be a special select committee on her breakfast, her lunch and her dinner and what she had in between." 
 
 But the email controversy has emboldened the wing of the Democratic party looking for a Clinton alternative in 2016. 
 
 Some early primary state Democrats told CNN's Peter Hamby that the controversy shows the need for a competitive primary that will help vet Clinton for the general election. 
 
 "The Democratic base that isn't wedded to her is nervous about it," said Deborah Arnie Arnesen, a progressive radio host in Concord, New Hampshire. 
 
 "These are problems that raise real leadership and transparency concerns, concerns that can be addressed in caucuses and primaries, but would go ignored in a coronation process," said Boyd Brown, a Democratic National Committee member and former state legislator from South Carolina. 
 
 Where do the laws stand? 
 
 The National Archives and Records Administration, the government agency that regulates the Federal Records Act, issued guidance in 2009 -- the same year Clinton took over at State -- that did not outlaw use of personal email accounts. 
 
 "Agencies that allow employees to send and receive official electronic mail messages using a system not operated by the agency must ensure that federal records sent or received on such systems are preserved in the appropriate agency recordkeeping system," the regulations said. It is unclear if there was a time requirement for the preservation of the emails. 
 
 Before 2009, according to Miriam Kleiman, spokeswoman for the National Archives, the agency did not "specifically address this issue." 
 
 "But agencies have always had the responsibility to manage federal records created or received outside of agency systems, including email on nonofficial systems," she added. 
 
 It wasn't until August 2013 -- after Clinton left State -- that the records administration issued a bulletin that personal email can only be used in "emergency situations," and when used, the emails "are captured and managed in accordance with agency record-keeping practices." 
 
 Late last year -- long after Clinton left the State Department -- President Barack Obama signed an update to the Federal Records Law to prohibit the use of private email accounts by government officials unless they copy or forward any such emails into their government account within 20 days. 
 
 Jason R. Baron, a lawyer at Drinker Biddle & Reath and the former director of litigation at the National Archives and Records Administration, said on Tuesday that it doesn't appear Clinton violated the law because "the Federal Records Act is amorphous enough." 
 
 Baron did say, however, that the exclusive use of a personal email system is out of the ordinary. 
 
 "I was in the government for 34 years and in my experience, as director of litigation, I cannot recall an instance where a high-level official -- or anyone -- solely used a private email account for the transaction of government business," he said.

 "The Select Committee on Benghazi today issued subpoenas for all communications of former Secretary of State Hillary Clinton related to Libya and to the State Department for other individuals who have information pertinent to the investigation," said Jamal Ware, the committee's communications director, in a statement. "The committee also has issued preservation letters to Internet firms informing them of their legal obligation to protect all relevant documents." 
 
 Rep. Trey Gowdy, chairman of the committee, told CNN on Wednesday, before the subpoenas were announced, that he was willing to do whatever it took to get the documents. 
 
 "We are going to use every bit of legal recourse at our disposal to make sure" the committee gets all the documents, Gowdy said. If that requires "sending legal resource to the secretary herself, that is what we are going to do." 
 
 Democrats on the committee said Wednesday that they received "no notice" from Gowdy that the committee was preparing subpoenas for Clinton's documents. 
 
 "I did not want to believe it, but everything I've seen so far has led me to believe that this is an effort to go after Hillary Clinton. Period. And I think that's very very unfortunate," said Rep. Elijah Cummings, the top Democrat on the select committee. 
 
 A spokesman for Clinton did not respond to CNN questions about the subpoenas, but Clinton's team has been in contact with the committee. 
 
 After Gowdy said Clinton used multiple private email addresses at State, Clinton's lawyer David E. Kendall sent Republicans and Democrats on the House committee investigating Benghazi a statement on Wednesday morning refuting Gowdy's claim. 
 
 "Secretary Clinton used one email account when corresponding with anyone, from department officials to friends to family," Kendall wrote in an email that explained how after Clinton's email address was published in a 2013 Gawker story, "she changed the address on her account." 
 
 "At the time the emails were provided to the department last year this new address appeared on the copies as the 'sender,' and not the address she used as secretary," Kendall continued. "This address on the account did not exist until March 2013, after her tenure as secretary." 
 
 Committee Republicans stood by Gowdy's claim, however, and reacted to Clinton's tweet about releasing her emails on Thursday. 
 
 "The former secretary's tweet does not answer questions about why this was not done when she left office, the integrity of the emails while she controlled them, the scheme to conceal them, or the failure to provide them in logical course," said Jamal D. Ware, communications director for the Republicans on the committee. "Legitimate investigations do not consider partial records. And that is the point of the subpoena issued yesterday by the Benghazi Committee." 
 
 Clinton isn't the first secretary to use personal email, but she is the first to use it exclusively 
 
 By using a private email system, Clinton and her aides had access to all emails that would have been backed up by the government if she had used an official account. 
 
 While she is not the first secretary of state to use a private email address -- former Secretaries Colin Powell and Condoleezza Rice both had private emails -- Clinton is the first to exclusively use a private account. As opposed to Clinton, both Rice and Powell had and used an official government email address. 
 
 An aide to Rice told CNN on Thursday that the former secretary of state "rarely used email during her tenure at State" and "on the very rare occasion she did, her State email was the vehicle for official communication. She did not use personal email for official communication as secretary." 
 
 Rice's aide said her office received the 2014 request from State to send in documents but "had nothing to turn over" to the department. 
 
 Powell, however, did use personal email to communicate with staff at State, but also had an official account. 
 
 A senior aide from the State Department said "Secretary Powell wrote in his book about his efforts to bring the State Department into the email age. He writes about how he installed a personal laptop in his State Department office to use his personal email to connect with his principal assistants, ambassadors and foreign ministers." 
 
 State spokeswoman Harf said this week that "Secretary Kerry is the first secretary of state to rely primarily on a state.gov email account." 
 
 Kerry responded to the Clinton controversy while traveling in Saudi Arabia on Thursday by sarcastically downplaying the importance of the story compared to his current mission abroad to deal with Iran's nuclear program. 
 
 "I believe we have all the emails, all the ones that are state.gov which are appropriately in purview of the department," he said. "But let me check on that when I actually have time to pay attention to such an important issue when I get home." 
 
 GOP calls for more investigations 
 
 Republicans wasted no time in jumping on an issue they see as a winning one. Their goal is to paint Clinton in the same way they painted her husband: A dishonest politician who pushes ethical boundaries and feels the rules don't apply to her. 
 
 The Republican National Committee sent the State Department Inspector General a letter on Thursday demanding an investigation into Clinton's use of private email. The letter, from John Phillippe, chief counsel at the RNC, questions whether Clinton violated "the requirement to archive emails that are federal records under the Federal Records Act." 
 
 "The American public deserves to know whether one of its top-ranking public official's actions violated federal law," the letter said. "With transparency and openness in government being one of President Obama's guiding principles, it is incumbent upon your office to determine the facts surrounding this issue." ||||| And Mrs. Clinton used this private address for everything — from State Department matters to planning her daughter’s wedding and issues related to the family’s sprawling philanthropic foundation.

 Six years later, as Mrs. Clinton prepares for a 2016 presidential campaign, her exclusive use of her clintonemail.com address while secretary of state has set off intense criticism, because it shielded her correspondence from being searched in response to public records requests at the State Department. The practice has also raised questions about whether Mrs. Clinton’s private email was vulnerable to security risks and hacking. 
 
 At the request of the State Department, Mrs. Clinton turned over about 50,000 pages of emails from clintonemail.com related to the government issues late last year. But her aides have declined to describe the process by which they selected which emails to hand over and which to hold back, and public records experts have expressed alarm that Mrs. Clinton’s correspondence was not being preserved as part of the State Department record-keeping system while she was in office. 
 
 Late Wednesday, Mrs. Clinton said in a Twitter message that she had asked the State Department to release her emails and that they would review them for release as soon as possible. “I want the public to see my email,” she wrote.

 “It seems her intent was to create a system where she could personally manage access to her communications,” said John Wonderlich, policy director of the Sunlight Foundation, a nonprofit organization that advocates transparency in government.

 “Given all the power she had as secretary of state, a lot of that work would be jumbled together,” Mr. Wonderlich said. “Her presidential ambitions and the family foundation would be wrapped up technically in email.”

 Mrs. Clinton’s allies have maintained that she followed protocol in the use of a private email address. A spokesman declined to elaborate on Wednesday about her use of clintonemail.com for matters related to the Clinton Foundation, which has received millions of dollars in donations from foreign governments. The foundation ceased to accept most donations from foreign countries while Mrs. Clinton was at the State Department but began the practice again after she left office in February 2013.

 In an email of talking points to supporters, Burns Strider, a senior adviser to Correct the Record, a group that defends Mrs. Clinton in the news media, pointed out that former Gov. Jeb Bush of Florida, also a likely 2016 presidential candidate, also hosts his own personal email server. 
 
 Mr. Bush is a prolific user of email who continued to use his personal jeb.org domain, which his aides could also access, while he was in the governor’s office, said Kristy Campbell, Mr. Bush’s spokeswoman. Under Florida’s records laws, emails from Mr. Bush’s personal account have been made public. “His emails were available via public records requests throughout his time in office and have remained available,” Ms. Campbell said. 
 
 In earlier years, Mrs. Clinton’s account at clintonemail.com was connected to a server registered to the Clintons’ Chappaqua home in the name of Eric P. Hothem. Mr. Hothem, a former aide to the Clintons, now works in finance in Washington, according to regulatory disclosure documents.

 Mr. Hothem, whose name was misspelled in Internet records, did not return a message left on Wednesday with an assistant at his office. Mr. Cooper, whose name is on the clintonemail.com domain registration, now works at Teneo Holdings, a corporate advisory firm with a broad array of global business clients partly run by Douglas J. Band, a former adviser to Bill Clinton.

 The Clintons eventually decided they did not want all three family members on the same email domain, in part, an adviser said, out of concern that it might look as if Mrs. Clinton’s official business at the State Department was too closely overlapping with Mr. Clinton’s work as a global philanthropist. Mr. Clinton stuck with presidentclinton.com, which was established in 2002. Chelsea Clinton has now set up chelseaoffice.com. The clintonemail.com domain is set to expire in 2017, when Mrs. Clinton, if successful in her presumptive campaign for president, would take office. 
 
 In addition to concerns that Mrs. Clinton’s private emails are not subject to requests under the Freedom of Information Act, there are also questions about how secure her personal email address was as secretary of state. 
 
 “She obviously would have been targeted when she stepped outside of the secure State Department networks,” said Tom Kellermann, a cybersecurity expert with Trend Micro. He said her use of her own email server instead of her government account, with its built-in security systems, would be akin to her leaving her bodyguard in a dangerous place. The unintended consequence, he said, is that Mrs. Clinton may have “undermined State Department security.”

 On Wednesday, a congressional committee examining the 2012 attacks in Benghazi sent a subpoena to Mrs. Clinton’s lawyers for all of her emails related to Libya. The committee sent the broad subpoena because it is seeking to determine whether Mrs. Clinton has handed over all of her correspondence about the attacks. Three weeks ago, the State Department provided the committee with roughly 900 pages of emails that the department said had come from her personal account. The committee also sent letters to Internet firms, telling them they were legally obligated “to protect all relevant documents” related to the Benghazi attacks.
– Hillary Clinton's personal email account may soon head for the public domain after all. Following news that a House committee on Benghazi would subpoena her emails, the former secretary of state tweeted yesterday, "I want the public to see my email. I asked State to release them. They said they will review them for release as soon as possible." That won't be instantaneous, says a State Department rep, who notes that "given the sheer volume of the document set, this review will take some time to complete." Aides for Clinton, who exclusively used a personal clintonemail.com email account while at the State Department, say she believed her emails would be collected as they were sent to government accounts, CNN reports. One adds "nine out of 10 emails that she sent over the course of her tenure went to the State Department." Others, however, have criticized her use of personal email as having made government communications vulnerable to attackers, because, as an ACLU technology expert tells Wired, "although the American people didn't know about this, it's almost certain that foreign intelligence agencies did, just as the NSA knows which Indian and Spanish officials use Gmail and Yahoo accounts." Clinton's email account was traced to a server registered to "Eric Hoteham." That's actually a typo: Former Clinton aide Eric P. Hothem now works in finance, the New York Times reports. Another former aide, Justin Cooper, registered the domain name, clintonemail.com, which expires in 2017. The Times notes having an address from clintonemail.com was "a symbol of status within the family's inner circle, conferring prestige and closeness to the secretary." Chelsea Clinton and longtime aide Huma Abedin are two within that group, though Chelsea's used a pseudonym: Diane Reynolds.
