Opinion for the Court filed by Circuit Judge BROWN.
Plaintiff-appellant Electronic Privacy Information Center (“EPIC”) filed a Freedom of Information Act (“FOIA”) request with the National Security Agency (“NSA”) seeking disclosure of any communications between NSA and Google, Inc. regarding encryption and cyber security. NSA issued a Glomar response pursuant to FOIA Exemption 3, indicating that it could neither confirm nor deny the existence of any responsive records. EPIC challenged NSA’s Glomar response in the district court, and the parties cross-moved for summary judgment. The district court entered judgment for NSA, and EPIC appealed. We affirm.
I.
EPIC’s FOIA request arose out of a January 2010 cyber attack on Google that primarily targeted the Gmail accounts of Chinese human rights activists. 1 Google *930 subsequently changed Gmail’s privacy settings to automatically encrypt all traffic to and from its servers. David Drummond, Google’s Senior Vice President for Corporate Development and Chief Legal Officer, stated that the company was notifying other companies that may have been targeted and was “also working with the relevant U.S. authorities.” David Drummond, A New Approach to China, Official Google Blog (Jan. 12, 2010), http://googleblog. blogspot.com/2010/01/new-approach-tochina.html On February 4, 2010, the Wall Street Journal and Washington Post reported that Google had contacted the NSA immediately following the attack. Former NSA director Mike McConnell commented in the Washington Post that collaboration between NSA and private companies like Google was “inevitable.” Mike McConnell, Mike McConnell on How to Win the Cyber-War We’re Losing, Washington Post (Feb. 28, 2010), http://www. washingtonpost.com/wp-dyn/content/ article/2010/02/25/AR2010022502493.html.
On February 4, 2010, EPIC submitted a FOIA request to NSA, specifically requesting three categories of records:
1. All records concerning an agreement or similar basis for collaboration, final or draft, between the NSA and Google regarding cyber security;
2. All records of communication between NSA and Google concerning Gmail, including but not limited to Google’s decision to fail to routinely encrypt Gmail messages prior to January 13, 2010; and
3.All records of communications regarding NSA’s role in Google’s decision regarding the failure to routinely deploy encryption for cloud-based computing service, such as Google Docs.
NSA responded to EPIC’s request on March 10, 2010 by invoking Exemption 3 of the FOIA and Section 6 of the National Security Agency Act 2 to issue a Glomar response, in which the agency neither confirmed nor denied the existence of any responsive records.
EPIC filed suit in the district court challenging NSA’s
Glomar
response.
3
The parties cross-moved for summary judgment. In support of its motion for summary judgment, NSA filed a declaration by Diane M. Janosek, NSA Deputy Associate Director for Policy and Records (the “Janosek Declaration”). The district court held that NSA was entitled to summary judgment because the Janosek Declaration was “both logical and plausible” and “contain[ed] sufficient detail, pursuant to Section 6, to support NSA’s claim that the protected information [sought by EPIC] pertains to” NSA’s organization, functions, or activities.
Elec. Privacy Info. Ctr. v. NSA,
*931 II.
The Freedom of Information Act, -5 U.S.C. § 552(a), provides that “[e]ach agency shall make available to the public” records in its possession unless the information is covered by one of Section 552(b)’s nine statutory exemptions. As relevant here, FOIA Exemption 3 shields from disclosure records that are “specifically exempted from disclosure by statute” if such statute either “requires that the matters be withheld from the public in such a manner as to leave no discretion on the issue” or “establishes particular criteria for withholding or refers to particular types of matters to be withheld.” 5 U.S.C. § 552(b)(3).
In addition to withholding records that are exempt, an agency may issue a
Glomar
response,
i.e.,
refuse to confirm or deny the existence or nonexistence of responsive records if the particular FOIA exemption at issue would itself preclude the acknowledgement of such documents.
See Wolf v. CIA,
In
Glomar
cases, courts may grant summary judgment on the basis of agency affidavits that contain “reasonable specificity of detail rather than merely conclusory statements, and if they are not called into question by contradictory evidence in the record or by evidence of agency bad faith.”
Gardels v. CIA,
NSA issued a
Glomar
response to EPIC’s request for records pertaining to the agency’s contact with Google, claiming that any responsive records would be exempt from disclosure under Exemption 3 and Section 6 of the National Security Agency Act, and that acknowledgement of the existence of such records would cause harm cognizable under the exemption. Because Section 6 of the National Security Agency Act “is a statute qualifying under Exemption 3,”
Founding Church of Scientology of Washington, D.C. v. NSA
EPIC claims its request seeks some records that are not covered by Exemption 3 and Section 6 of the NSA Act — specifically, unsolicited communications from Google to NSA, which would fall within the second category of information described in the request. In light of the broad language of Section 6, however, we find the Janosek Declaration provides adequate support for NSA’s Glomar response. As the Declaration explains, one of NSA’s primary cryptologic missions is its Information Assurance mission, under which NSA is tasked with protecting Government information systems. Because the Government is “largely dependent on commercial technology for its information systems,” NSA also monitors commercial technologies purchased by the government for security vulnerabilities. Janosek Dec’l ¶ 6. If NSA concludes that vulnerabilities in those commercial technologies pose a threat to U.S. Government information systems, NSA may take action against the threat.
The Declaration further explains that if NSA disclosed whether there are (or are not) records of a partnership or communications between Google and NSA regarding Google’s security, that disclosure might reveal whether NSA investigated the threat, deemed the threat a concern to the security of U.S. Government information systems, or took any measures in response to the threat. As such, any information pertaining to the relationship between Google and NSA would reveal protected information about NSA’s implementation of its Information Assurance mission. The existence of a relationship or communications between the NSA and any private company certainly constitutes an “activity” of the agency subject to protection under Section 6. Whether the relationship — or any communications pertaining to the relationship — were initiated by Google or NSA is irrelevant to our analysis. Even if EPIC is correct that NSA possesses records revealing information only about Google, those records, if maintained by the agency, are evidence of some type of interaction between the two entities, and thus still constitute an NSA “activity” undertaken as part of its Information Assurance mission, a primary “function” of the NSA. Moreover, if private entities knew that any of their attempts to reach out to NSA could be made public through a FOIA request, they might hesitate or decline to contact the agency, thereby hindering its Information Assurance mission.
EPIC’s attempt to liken this case to
Founding Church of Scientology,
in which this Court found the agency’s affidavit too conclusory to support the NSA’s rejection of a FOIA request,
see
*933
EPIC also attempts to distinguish this Court’s prior interpretations of Section 6 because those cases involved requests for records relating to the NSA’s classified intelligence gathering activities and sources.
See, e.g., Larson,
Moreover, NSA does not waive its protection under FOIA by disclosing basic information about its information assurance activities. The fact that limited information regarding a clandestine activity has been released does not mean that all such information must be released.
See Students Against Genocide v. Dep’t of State,
III.
Subsection (b) of the FOIA provides that “[a]ny reasonably segregable portion of a record shall be provided to any person requesting such record after deletion of the portions which are exempt under this subsection.” 5 U.S.C. § 552(b). In response to a FOIA request, agencies “must make a good faith effort to conduct a search for the requested records, using methods which can be reasonably expected to produce the information requested.”
Nation Magazine, Washington Bureau v. U.S. Customs Serv.,
EPIC argues that Section 552(b) requires NSA to search for responsive documents and conduct a segregability analysis prior to issuing a
Glomar
response. We rejected a similar argument in
Wolf,
and EPIC is no more persuasive. In
Wolf,
the requester claimed that
de novo
review of the agency’s response “requires the district court to order the Agency to search for responsive records and to submit a
Vaughn
index.”
EPIC claims this Court has upheld
Glomar
responses “only in cases where it is apparent from the record that the Agency first conducted a search and segregability analysis, and even disclosed or withheld specific responsive records,” Appellant’s Br. 25. This is inaccurate. In the cases cited by EPIC, the agency conducted a search and segregability analysis of its own volition prior to issuing the
Glomar
response.
See, e.g., Larson,
EPIC’s reliance on
Jefferson v. Dep’t of Justice, Office of Profl Resp.,
IV.
For the foregoing reasons, the decision of the district court is
Affirmed.
Notes
. Gmail is a “cloud-based” email program, meaning the data and applications of the user reside on remote computer servers operated *930 by Google. Prior to January 2010, Google allowed Gmail users to encrypt the mail that passed through Google servers using Hypertext Transfer Protocol Secure, but it did not provide encryption by default.
. Section 6 of the National Security Agency Act provides that "nothing in this Act or any other law ... shall be construed to require the disclosure of the organization or any function of the National Security Agency, [or] of any information with respect to the activities thereof....” Pub.L. No. 86-36, § 6(a), 73 Stat. 63, 64 (1959).
. EPIC initially filed an administrative appeal, arguing that NSA's response was unlawful because the agency had failed to present factual evidence that the requested documents fell within Section 6, but filed suit in the district court prior to the resolution of that appeal.
. The
Glomar
response takes its name from the
Hughes Glomar Explorer,
“a ship built (we now know) to recover a sunken Soviet submarine, but disguised as a private vessel for mining manganese nodules from the ocean floor.”
Bassiouni v. CIA,
. EPIC’s claim that collaboration between Google and NSA was “widely reported in the national media and acknowledged by the former director of the NSA” is similarly unavailing. Appellant’s Br. 19. NSA has never officially acknowledged a collaborative relationship with Google, and the national media are not capable of waiving NSA’s statutory authority to protect information related to its functions and activities.
