Cloud Computing and Privacy FAQ
David TS Fraser
In Canada, there is often a perception that using cloud computing services may be against the law or may undermine privacy. This is often not the case, but the perception remains. The purpose of this frequently asked questions is to dispel some of the mythology and to provide the reader with a framework so that cloud computing and privacy can be properly assessed.
One important consideration for anyone contemplating a cloud computing solution is that the “baseline” from which you should measure any potential decision is your existing information system, warts and all. As objectively as possible, you will need to consider the security and privacy risks that are inherent in your corporate infrastructure. This may include insecure desktop systems, users with unencrypted mobile devices and constantly playing catch-up with patches and security updates. When making comparisons about the different options, keep your eyes as open as you can. Also, factor in the cost of bringing your existing system up to your desired standards as a matter of comparison.
No. There is no law that prevents most Canadian businesses from “exporting” personal information. Private sector privacy laws require that you ensure a comparable level of security for personal information, regardless of whether you permit it to be managed by a Canadian company or a non-Canadian company. (Some highly regulated industries, such as banking, have special rules which may include additional regulation for outsourced services.)
It depends on the jurisdiction of the public sector or government body. Only British Columbia and Nova Scotia have laws strictly regulating the export of personal information from Canada by public bodies. For all other jurisdictions, including the federal jurisdiction, export is permitted but the public body must ensure a comparable level of security for personal information, regardless of whether you permit it to be managed by a Canadian company or a non-Canadian company.
Alberta has enacted legislation that makes it an offense for a public body or a service provider to disclose personal information in response to an order that does not have jurisdiction in Alberta.
In 2001, the United States Congress passed the USA Patriot Act, which expanded the powers of law enforcement and national security agencies to carry out investigations and to obtain intelligence in connection with anti-terrorism investigations. Investigative powers that had been restricted to counter-intelligence (spy vs. spy stuff) were extended to anti-terrorism investigations. In Canada, attention was focused on the USA Patriot Act when the British Columbia government proposed to outsource processing of medicare claims to the Canadian subsidiary of a US company. Public sector unions who opposed the outsourcing focused on the fact that the company was American and suggested that sensitive health information would be readily available to US authorities. The British Columbia Information and Privacy Commissioner carried out an inquiry into the impact of this outsourcing on the privacy of British Columbians and recommended wide prohibitions on the “export” of personal information by BC’s public bodies.
British Columbia amended its Freedom of Information and Protection of Privacy Act to prohibit the export of personal information. (It is notable that the government did outsource the processing to the Canadian subsidiary of the US company and the legislature has had to amend the Act to scale back some of the unworkable provisions.) For more information, see below.
Nova Scotia followed suit with the passage of the Personal Information International Disclosure Protection Act. For more information, see below.
Amendments to the Freedom of Information and Protection of Privacy Act require that information under the custody and control of a public body be stored only in Canada and accessed only in Canada unless the individual has consented to its storage or disclosure outside of Canada or one of a number of narrow exceptions apply. The public body and any of its service providers are under a legal obligation to report any foreign demands for disclosure. Violating any of these provisions is an offense.
The Personal Information International Disclosure Protection Act requires that information under the custody and control of a public body be stored only in Canada and accessed only in Canada unless the individual has consented to its storage or disclosure outside of Canada or one of a number of narrow exceptions apply. Importantly, the head of a public body may authorize the storage of personal information or access to personal information from outside of Canada if the head of the public body determines it is for the necessary operations of the public body. The head is obliged to report these exceptions to the Minister of Justice after the year end in which these decisions are made.
The public body and any of its service providers are under a legal obligation to report any foreign demands for disclosure. Violating any of these provisions is an offense.
Not necessarily. The provisions of the USA Patriot Act that have attracted the most criticism have equivalents under Canadian law. Regardless of where information resides, it will always be subject to lawful disclosure to law enforcement or national security bodies. In Canada, this includes search warrants under the Criminal Code of Canada and the Canadian Security Intelligence Service Act, and administrative subpoenas such as those issued under the Income Tax Act.
It should also be noted that many European countries permit broader law enforcement and national security access to information than in both the United States and Canada.
Secret Court Orders - The Foreign Intelligence Surveillance Act (amended by the USA Patriot Act) permits a specialized court - the Foreign Intelligence Surveillance Court - to issue secret court orders for the production of “any tangible thing” in connection with terrorism investigations. These orders are accompanied by a “gag order”, which prevents the recipient of the order from telling anyone other than legal counsel about the order. Canadian authorities have virtually identical powers under the Canadian Security Intelligence Service Act, which permits secret court orders that authorize CSIS to intercept communications or to obtain any thing named in the warrant.
Warrantless Wiretapping - The Foreign Intelligence Surveillance Act law permits the American government to intercept foreign communications and international communications without a warrant. Canada’s National Defence Act has essentially the same powers.
National Security Letters - National Security Letters are a form of administrative subpoena that permits a senior official of the Department of Justice to compel a third party (such as a bank, a telecom provider or an Internet service provider) to hand over information about a person’s use of the third party’s services. For example, they can require a telephone company to provide information about a customer’s use of the telephone, such as phone numbers called and the phone numbers of callers to the target of surveillance. It does not authorize the provision of the contents of any communications. Canada does not have an equivalent, but authorities in Canada can obtain this information by use of production orders.
In short, no. Canada, the United States and most western democracies engage in a very high level of cooperation that includes mutual legal assistance treaties and ad hoc information sharing. If US agencies are interested in an individual who has ties to Canada, the Federal Bureau of Investigation can make a formal request of the Royal Canadian Mounted Police or CSIS to obtain the relevant information on their behalf. Most Canadian privacy laws actually permit this sort of information sharing under treaties or informal arrangements. And if you are concerned about covert access to this sort of data, American laws do not prohibit federal agencies from seeking the information covertly if it is not in the United States. Some have suggested that information is safer from US authorities in the US because of this.
Under most Canadian laws, you technically do not need to seek consumer consent or provide notice. However, the Privacy Commissioner of Canada has taken the position that businesses that propose to have personal information processed outside of Canada should give notice of this to customers. This is not required under the statute, but probably represents a best practice. If you are required to give notice or elect to as a best practice, you should be mindful of how it is presented to your customers so that it does not appear to be a request for consent that they can “opt out” of or that raises concerns. Under the Alberta and Quebec private sector laws, you are required to give notice of this to your customers.
Canadian legislation is silent about what particular security practices should be adopted when using cloud computing. The Personal Information Protection and Electronic Documents Act, for example, only says that safeguards must be adopted that are commensurate with the sensitivity of the information. The more sensitive the information, the greater the precautions that should be taken. The general prevailing view is that you should insist on at least the industry best practices for the sort of data at issue.
The original organization remains legally responsible for the safeguarding personal information even if it is outsourced. It is up to the organization to make sure that any service provider implements adequate protections.
One must be mindful of any additional risks introduced by cloud computing, which is principally related to having data in transit over the open Internet. These risks can generally be mitigated by the use of SSL, VPN or other encryption technologies to make the information safe in transit.
When evaluating the security and privacy implications of outsourcing services, you should benchmark the provider against the status quo at your organization. If the provider you are considering is compliant to a national or international standard such as ISO27001 or FISMA/FIPS or SAS 70, consider whether your current systems would be compliant.
Provided a reputable provider is used, information is generally safer when in the custody of a cloud service provider. This is generally because cloud providers have greater resources to devote to security and because mobile users will no loner have to carry data with them in vulnerable devices, such as laptops and USB/thumb drives.
Jurisdiction is not irrelevant, but is less relevant that many people believe. For example, you should be very wary of any situation that casts doubt over whether your contract with your service provider will be enforceable. Afterall, their obligations to secure your data are set out in the contract. This means, at a minimum, you should be sure that your service provider is based in a jurisdiction with a mature and fair legal system. You should be aware that data may fall under the jurisdiction of any country that is reasonably connected to, so this would include at a minimum where you are located, where the service provider is based and where the data resides (which may be difficult for the customer or any third party to determine). For each of these jurisdictions, you should consider whether any them introduce any significantly meaningful increase in risk to your data. Expert legal advice should be sought as it is very difficult to determine and measure this risk.
Below is a list of what you should be asking for. Not every service provider will negotiate these terms and some are simply difficult or impossible to deliver depending on the model of cloud computing the provider uses, but you should ask for them and consider any response.
1. Limit service provider to only using your data for your purposes and for no other purpose
Depending on the service, it is reasonable that your provider will want to gather analytics about how users use the service so they can improve it, but the provider should be limited in what possible secondary uses they can make of your own data. In most cases, they should not make any use of this data for their own purposes unless you explicitly consent.
2. Include provision that data is held “in trust” for customer
The purpose of this stipulation is to make it clear that the data remains yours and their role is to process/store/manage it on your behalf. In addition, if the data is held for you in trust, their obligations with respect to the data are increased as they are a legal fiduciary.
3. No disclosures of information without your consent
The provider should not permit -- and should be legally responsible for -- any disclosures of your data other than as expressly set out in the service agreement. The service agreement should contemplate what the provider should do to respond to a legal order for access.
4. Liquidated damages for any disclosure without consent
It is often difficult to quantify the harm resulting from disclosure of information, so it is a good idea to try to set out in the agreement a reasonable sum of damages that the service provider should pay in the event of a disclosure without your consent. It should not be a fixed sum, but rather a multiplier connected to the extent of the disclosure. And make sure that it is “general damages”, so that you are not precluded from claiming additional damages for the out-of-pocket costs associated with any claims made by your customers against you, any fines that may be levied and your costs associated with notifying your customers.
5. Obligation to resist – to the extent lawful – orders to disclose information without consent
If the service provider receives legal process that would require them to hand over the data and they are not able to tell anyone about it, this would make it mandatory for them to resist the disclosure to the extent that they can. For example, if they receive a subpoena or a production order, they should not just hand it over but apply to the issuing court to have the subpoena quashed. (There is never any assurance that it will be successful, however.) It should be noted that some orders, such as search warrants, cannot be resisted at the time but an application can be made to have the warrant set aside and the data returned.
6. Obligation to cooperate with you in any regulators’ investigations
In the event of any investigation by the Privacy Commissioner or some other regulator, your service provider should be obliged to assist you with such an investigation.
7. Will not deal with any regulators related to your information without your participation
In the event of any investigation by the Privacy Commissioner or some other regulator, your service provider should not be dealing directly with the investigators. It is your data and you are ultimately responsible for it, so the job of addressing any complaints should be yours alone.
8. Implement safeguards to protect information – Set minimums but shift as much responsibility to the service provider
Cloud computing agreements are complicated, technologies are subject to constant change and security standards shift over time, so it is better to have the service provider agree to abide by well-known information security standards instead of dictating particular technologies to use. Make sure your provider is regularly audited against these standards and make sure that you will have the right to obtain copies of the audit reports. It is unlikely that you will be able to audit them yourselves (which is a good thing, because you don’t want other customer’s auditors going through the systems on which your data resides).
Make sure they warrant that they will abide by these standards and that they will cover all of your costs in the event of any breach that results from their lapse.
If possible, you should make sure that you are able to audit your users’ access of the data, which may be necessary if there is a breach of security that originates within your systems.
9. Do not accept any limitations of liability related to privacy and security – full indemnity
One of the reasons for choosing a cloud provider is because of their expertise in securing your data. The agreement should not limit their liability to a nominal amount if they fail to safeguard the data. Their warranty and indemnity should cover all of your costs and any remedies you have to offer your customers due to a security breach. The service provider should have adequate insurance for incidents such as these and the provider should be obliged to keep their insurance in force and to provide you with certificates of insurance evidencing this.
10. No retention of your information after the contract is finished (and make sure you get all your data back!)
You should make sure that any contract with your service provider permits you to get all our data out if you choose to terminate the agreement or if it expires and that the provider cannot retain or use any of your data (other than general analytics information that is used to improve the service) after that point. It just makes sense.
As with any new program that involves the handling of personal information, the organization should undertake a privacy impact assessment (also known as a “PIA”). PIAs are a systematic way of canvassing all of the privacy issues inherent in a project so they can be identified and hopefully mitigated. PIAs are widely done in the public sector and should be undertaken by private sector organizations who are considering moving customer or employee data to a service provider. The author has considerable experience with PIAs and can provide training and additional information.
