Lessons from Data Breaches

More than 6 million Canadians were impacted by the Capital One data breach that happened this year – and that was not even the biggest breach by any stretch. The biggest data breach is still Yahoo, whose breach impacted more than 3 billion people. Big or small, however, each data breach is costly and damaging – to consumers, to businesses, and to the economy. We can – and should – learn everything we can from these incidents to avoid repeating them. In analyzing security breaches that have occurred over the last 10 years, experts found that the main reasons data breaches occur are:

• Failure to patch
• Human error
• Insider attacks
• Poor mobile device management

Failure to Patch

Too often, a breach occurs because an organization has delayed patching, leaving them vulnerable to hackers. This often happens because the organization does not have a dedicated IT staff, leaving one or more employees responsible for IT on top of their other duties. Those other duties – their “real” jobs – take priority and patching jobs get postponed.

Partnering with a managed services provider (MSP) can help solve this problem and extend the strength of your IT team, whether your team is a whole department, or one person assigned with additional responsibilities. An MSP ensures patches are installed in a timely manner, but they’re also there to monitor your network 24/7.

Human Error

Clicking links and opening attachments in emails that appear to come from within your organization or from a trusted vendor cause more data breaches than we can measure. It’s possible your organization has malware sitting on your network right now that has been introduced by an errant employee and has yet to have been detected.

While we can never completely remove human error from the equation, we can drastically reduce the number of email-related data breaches by:

• Developing, implementing, and enforcing strict zero-trust policies
• Providing ongoing training to employees to help them recognize potential phishing scams
• Limiting the data to which employees have access
• Requiring multi-layer authentication that includes complex passwords and other access barriers

Insider Attacks

Insider attacks don’t account for many data breaches, but they can be the most devastating simply because of the betrayal involved. According to the 2019 Verizon Data Breach Investigations Report, insider threats are on the rise, accounting for 34% of data breaches. In one case highlighted in the DBIR, a hacker admitted that when all other efforts failed, he bribed an employee to get him inside the network.

Preventing insider attacks can be difficult; they are often only discovered after the fact during forensic analysis– and often after the employee is long gone. But you can minimize the risk of insider threats by having multiple layers of security, strictly limiting employee and third-party access to data, and by conducting regular audits. Often, insider attacks come from former employees whose access to the network was not terminated; make it protocol to immediately revoke all access to employees who leave – whether they leave on good terms or not.

Poor Mobile Device Management

Mobile phones are being used to conduct business whether you authorize it or not, so your best bet for protecting your organization is to have a highly sophisticated MDM security plan in place that includes the following:

• Strict usage requirements that include installing your security on the device being used and requiring the use of a secure network when conducting business
• Remote wipe capabilities to disconnect the device from your network in the event that it is stolen, or the employee leaves the organization
• A no-tolerance policy for any employee who refuses to comply with the security requirements

Data breaches are not going away, but you can minimize the risk to your organization with strong IT security and a comprehensive disaster recovery plan. You can’t just address one of these issues; you must have a comprehensive, proactive data security program that addresses all of these risks and more.
