Telcos and information privacy

With the economy in the tank, breach of privacy is not going to be a priority in Obama’s administration to do list. It will be quite difficult to make it a priority when Obama has signed a bill indemnifying telcos from suits due to privacy breaches.

During the presidential election campaign, Verizon employee gained unauthorized access to President-elect Obama’s mobile phone records. You might assume that if telcos are having a hard time protecting the privacy of high profile individuals, how would that make you feel as a cell phone owner? Don’t you wonder why the mainstream media didn’t publicize this case of high profile privacy breach more widely?

Basically Telcos have been immunized from privacy lawsuits so that big brother can snoop around our private phone records as they please. In this instance, law only applies to people and makes it illegal to snoop on each other but the telecom entities have been granted an exception by congress. Legal ruling require law enforcement to meet high “probable cause” standard before acquiring cell phone record. In recent report, document obtained by civil liberties group under FOIA request suggest that “triggerfish” technology can be used to pinpoint cell phone without involving cell phone provider and user knowing about it.

Organizations should implement directive, preventive and detective controls to protect the privacy of information. Where directive controls include the policies, procedures, and training. Preventive controls deal with the separation of duties, principle of least privilege, network, application and data controls. Detective controls involve auditing, logging and monitoring.

Verizon case shows lack of detective controls. Organization should have a clearly defined privacy policy which states that private information should be logged, monitored and audited. High profile individual should be identified and documented and reviews of audit logs should be conducted to identify inappropriate access to the privacy information of high profile individuals. The authorized person who has access to private information should be audited on regular basis to find out if they are following the privacy policies and procedures of the company. For privacy information, log who accessed which data, for who and when. Managers should train and monitor subordinate to help protect privacy information, which not only educate the subordinate but also serve as a major deterrence. Privacy is an essential ingredient of liberty and must be guarded with utmost due diligence.

Open Network and Security

Open networks are heterogeneous environment where users like to use all the applications and systems at any given time. In a heterogeneous environment, each department run different hardware and software, but you can control the protocols which will work on this environment.

Universities are famous for open network. Most Universities network is comprised of a Bank (To give loan to students), a restaurant, and a bookstore which have credit card processing ability. Students, alumni, researchers, employee and staff need access to utilize resources. Now how would you control access if same person assume all the roles mentioned above. Universities are basically transient communities, where users come back and plug-in their new devices and expect an immediate access to all the resources. Where the reputation of openness is challenge at every step of the way, now the question is how can they maintain reputation and yet control the environment based on security policies.

Reasonable security can be accomplished by focusing on a process rather than adding yet another security control. The process is based on risk assessment program where you assess your critical assets based on threat and vulnerability pair and measure the likelihood and impact of a threat if a given vulnerability is exploited.

The process start with knowing your assets – Network registration will detect when you plug-in your new equipment. Before you get an access, it detects a hardware address and username. You can also control common misconfigurations and noncompliance issues with network registration process. Some vulnerability management systems discover assets and perform vulnerability and security configuration assessment to proactively identify and prioritize risks. New vulnerabilities are accessed from trusted site on a regular basis and when vulnerabilities are identified, the management system needs to have an ability to remediate to comply with the information security policy.

Most of the departments in an open network contains different systems and applications and basically have different security appetite. Distributed IT Governance can address this issue where you develop policies and procedures which fit their needs and hand it over to the department to comply.
Open network requires pretty much open borders, Instead of securing the network/system emphasis should be on data protection.

Recent news from AT&T to make its network open where customers can use any handset of their choice, perhaps a reaction to in response to recent moves from Verizon and Google to promote open network. Specifically Verizon announced that it would allow “any device” and “any application” to operate on its network. These open networks does provide flexibility for customers but at the same time burden lies on the shoulders of the corporations to provide right balance of security and privacy with availability of the network.

In an open network, reasonable security can be achieved by embracing ISO 27k standard and eventually acquiring ISO 27001 (ISMS) certification. Information Security Management System (ISMS) can be a great value added process to manage ongoing monitoring, maintaining and for process improvement of an open network. ISMS as a process in-place provides reasonable security safeguard to your information and certainly help to minimize the liability in the court of law.
