Data security and privacy: A holistic approach Download here |
"Our Steam forums were defaced on the evening of Sunday, Nov. 6," said Gabe Newell, co-founder and managing director of Steam parent company Valve, in a statement on the company's website. "We began investigating and found that the intrusion goes beyond the Steam forums.
"We learned that intruders obtained access to a Steam database in addition to the forums," Newell wrote. "This database contained information including user names, hashed and salted passwords, game purchases, email addresses, billing addresses and encrypted credit card information."
Valve can't say for sure whether the hackers got away with any personally identifying information, but it did say the credit card numbers were encrypted.
"We are still investigating," the statement says. "We don’t have evidence of credit card misuse at this time. Nonetheless you should watch your credit card activity and statements closely."
Only "a few forum accounts" have been compromised, according to Newell, but all forum users will be required to change their passwords. "We do not know of any compromised Steam accounts, so we are not planning to force a change of Steam account passwords, which are separate from forum passwords," the statement says. "However, it wouldn’t be a bad idea to change that as well."
Steam will reopen its forums "as soon as we can," the statement says.
"Gaming companies are the new gold mine of consumer identity information for hackers," says Wasim Ahmad, data protection expert and vice president at security vendor Voltage Security. "Few of them have thought about security the way that, say, financial services companies do.
"Truth is, hackers always find a way to get to the data, so securing data itself is a main priority," Ahmad says. "Looking for evidence of tampering or trying to keep intruders out is not a sufficient security strategy.”

Securing The Data Warehouse
Many enterprises are building data warehouses to centralize the ever-increasing information flowing through their organizations into useful repositories. This makes good business sense, but it opens up a slew of concerns from a security standpoint. IT professionals can apply many of the same security best practices used with databases, but there are new lessons to be learned as well.
Defend Your Data From Malicious Insiders
The biggest threat to your company?s most sensitive data may be the employee who has legitimate access to corporate databases but less-than-legitimate intentions. And while the incidence of insider data breaches has decreased, external attacks often imitate them--and do serious damage. Follow our advice to mitigate the risk.
Ensuring Secure Database Access
Role-based access control based on least user privilege is one of the most effective ways to prevent the compromise of corporate data. But proper provisioning is a growing challenging, due to the proliferation of "big data," NoSQLdatabases, and cloud-based data storage.

Establishing a Strategy for Database Security is No Longer Optional
As databases continue to grow in size, complexity and importance, enterprises struggle to identify the most appropriate controls regarding their use and misuse. The report identifies best practices, including: Implementing database activity monitoring to mitigate the high levels of risk from database vulnerabilities, and address audit findings in areas such as database segregation of duties and change management; using data security measures, such as data masking and data encryption; and monitoring privileged-user access and access to critical data.
Database Activity Monitoring Is Evolving Into Database Audit and Protection
In this report, Gartner writes that "Database audit and protection (DAP) represents an evolutionary advance in database activity monitoring tools." DAP suites provide comprehensive, cross-platform support in heterogeneous database environments to protect sensitive data from inappropriate use. Organizations are increasingly concerned with optimizing database security and mitigating risks associated with database vulnerabilities.
Protecting Against Database Attacks and Insider Threats: Top 5 Scenarios
Data security presents a multi-dimensional challenge in today's complex IT environment. Multiple access paths and permission levels have resulted in a broad array of security threats and vulnerabilities. We invite you to read this new eBook: "Protecting against database attacks and insider threats" to learn the top five scenarios and essential best practices for preventing database attacks and insider threats.
Demo: Distributed Database Security with Real-time Monitoring and Audit Protection
Organizations across the globe continue to experience compromised data caused by malicious attacks, web application vulnerabilities or unauthorized changes. View this demo and learn how IBM InfoSphere Guardium? database activity monitoring can help protect your sensitive data in distributed DBMS environments with a holistic approach to data security and compliance.
Look Beyond Native Database Auditing To Improve Security, Audit Visibility, And Real-Time Protection
Today's attacks on enterprise databases are more sophisticated than ever, and they occur so fast that it's often difficult to stop them in real time. Despite significant efforts to protect enterprise databases, the number of records breached has grown each year - due to all types of internal and external attacks and violations of corporate policy.
