Security breach and notification

California was the first state in the nation to pass a data breach notification law in 2003, and it’s now planning to broaden the notification for companies doing business in the state. Notification will require specific information about the breach to the consumer and send notices to the state authorities at the same time.

The notices which consumers currently receive are basically too little too late, meaning they might say that your information may have been compromised and these notices may be released several months after the incident.

California’s new legislation will force the organization to admit the extent of the compromise, so consumers can assess their own risks in a timely manner. Heartland, the credit card processor, has been sued by the banks to recover the breach notification cost. Should the credit card processing company which had a security breach be responsible for the cost of the notification?

Current notification does not inform you where and how your credit card information was compromised so that at least you can stop shopping from that merchant. When consumers ask specific questions regarding the breach to the credit card company customer service representative, they will deny any knowledge of the breach and will say something along the lines of, when all the legal information has been taken care the credit card company will send you a detailed letter about the breach.
Now in case of a processor security breach, the credit card company might issue notices to several hundred thousand people. Without specifics, that particular notice might have “crying wolf” effect and consumers might not take any action.

Last week a well publicized security breach at UC Berkeley exposed the records of 160,000 people. The hackers had access to the vulnerable system for more than six months before they were discovered, which clearly shows lack of monitoring control and due care.
When a young college student affected by the breach receives a “may have been breached” notice he or she immediately will worry about his/her credit and possibility of identity theft. Now the question is why a student has to bear the burden of the negligence by the merchant or campus and lack of reasonable security safeguards. After issuing such notice that the private information “may have been compromised,” the responsibility of keeping an eye on your credit is transferred to you. The problem is some fraudulent transactions might not be noticed for at least a year.

Open Network and Security

Category: Information Security,Open Network — DISC @ 7:54 pm

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.
