Internet Security: Protecting From Data Breaches on the Inside

Last week we discussed internet security, how to create a “digital fortress” with defense in depth.  If you have all of the systems in place that we discussed you probably believe yourself secure.  Although you are more secure than many, there are still chinks in the armor that can be exploited.  One such potential problem arises with employees using their own devices (BYOD).  For the longest time, it was believed that the only defense against a threat from a personal device was anti-virus software on all your workstations and servers.  Certainly, it is important for network security to have anti-virus software, however, no A/V software is 100% secure.

Why Anti-Virus Software Does Not Always Work

The problem with A/V software arises because bad guys are constantly developing viruses and malware that exploit security holes and then the anti-virus community reacts to these attempts. This means there is always a lag time between the creation of a virus and the deployment of an update to the A/V software that protects against the new threat.  During this time your network is at risk.

With BYOD we can add a second or even third level of defense.  Many antivirus vendors now offer a version for Android and IOS. Therefore enforcing a BYOD policy that requires A/V software on all devices that connect to your network is becomes an additional line of defense.  Furthermore, modern security appliances, like the Meraki MX series have an option that includes Stateful, layer 3-7 deep packet inspection, intrusion detection and prevention, content filtering and a host of other applications designed to keep your network secure.

Stateful Packet Inspection: Information Security from the Inside Out

Effectively, this appliance looks deep into the individual data packets and determines if there is a threat.  If edge security is the equivalent to having security guards at the gate to your fortress, think of this as guards roaming throughout the fortress.  These guards effectively strip search every packet they come across and make sure they aren’t bringing, leaving with, or carrying something they shouldn’t.  This provides us additional defense in depth with protection on the portable device, the router and the individual permanent devices on the network.

In spite of all of this protection, no system is perfect.  There are non-digital threats to your data, such as fire, flooding, and other force majeure events.  In these cases, prevention is not as important as recovery.  Next week we will discuss disaster recovery considerations.

Meeting IT security compliance standards is crucial for businesses that handle sensitive data, particularly in industries such as healthcare, finance, defense, and e-commerce. Regulatory frameworks such as HIPAA, CMMC, PCI-DSS, and GDPR exist to help ensure businesses protect customer information and maintain robust cybersecurity practices. Unfortunately, many organizations fall short of these requirements, often due to common, avoidable mistakes. These gaps can result in costly fines, data breaches, and reputational damage, which can significantly impact the business's bottom line and customer trust. 1. Failing to Conduct Regular Risk Assessments The Pitfall: Many businesses overlook the importance of conducting routine risk assessments. Without these, it’s challenging to identify vulnerabilities or evaluate whether your current cybersecurity controls meet compliance standards. How to Avoid It: Implement a regular risk assessment schedule. Work with a qualified IT provider to evaluate your systems, identify weaknesses, and document remediation plans. These assessments should be performed at least annually, or whenever significant changes to the system occur. 2. Inadequate Employee Training The Pitfall: Your employees are your first line of defense—and often your most significant vulnerability. A common compliance issue arises when businesses fail to train staff on cybersecurity best practices or on handling sensitive data appropriately. How to Avoid It: Invest in ongoing cybersecurity awareness training. Ensure employees understand how to recognize phishing emails, create strong passwords, and report any suspicious activity. Training should be updated regularly to reflect current threats and compliance requirements. 3. Improper Data Handling and Storage The Pitfall: Storing sensitive data in unsecured locations, failing to encrypt information, or retaining data longer than necessary are significant compliance risks. These practices are often flagged during audits. How to Avoid It: Adopt data classification policies that define how different types of data should be handled; encrypt sensitive data both at rest and in transit. Establish clear data retention policies and ensure that obsolete data is disposed of securely. 4. Lack of Incident Response Planning The Pitfall: When a security incident occurs, time is of the essence. Many businesses lack a documented incident response plan, or their existing plan hasn’t been thoroughly tested. This can lead to delayed responses, increased damage, and regulatory penalties. How to Avoid It: Develop a formal incident response plan that includes roles, responsibilities, communication protocols, and steps for containment and recovery. Run simulated breach scenarios with your IT team to ensure everyone knows how to respond effectively. 5. Using Outdated Software or Systems The Pitfall: Running outdated operating systems, software, or firmware is a common issue that can lead to compliance failures. Unsupported technologies are more vulnerable to exploitation. How to Avoid It: Keep all systems and applications up to date with the latest patches. Use automated tools to track software versions and receive alerts about end-of-life technologies. Schedule regular maintenance windows to apply updates and upgrades. 6. Insufficient Access Controls The Pitfall: Allowing too many employees access to sensitive data—or failing to revoke access when it’s no longer needed—can lead to data breaches and non-compliance. How to Avoid It: Implement role-based access controls and follow the principle of least privilege. This principle means that each user should have the minimum level of access necessary to perform their job. Regularly audit user accounts and permissions to ensure access is current and appropriate. Use multi-factor authentication (MFA) to add an additional layer of protection. 7. Neglecting Third-Party Vendor Risks The Pitfall: Businesses often overlook the fact that their compliance responsibilities extend to third-party vendors. If a vendor mishandles your data, you could still be held accountable. How to Avoid It: Vet third-party vendors carefully. Ensure they meet the same compliance standards as your business and include security requirements in your contracts. Conduct periodic audits or request compliance certifications from your vendors. 8. Failing to Document Policies and Procedures The Pitfall: Even if your security practices are strong, failing to document your compliance policies can result in audit failures. Regulators want to see evidence that you have formal processes in place. How to Avoid It: Create and maintain clear documentation for all compliance-related policies, including data protection, access control, incident response, and employee training. Make these documents easily accessible for audits and regularly review them to ensure updates are current. Conclusion Compliance with IT security standards is not a one-time project—it requires ongoing attention, regular updates, and a proactive approach to maintain effectiveness. By understanding and addressing these common pitfalls, your business can stay ahead of regulatory requirements, strengthen its security posture, and reduce the risk of costly incidents. This ongoing attention is crucial to maintaining your business's security and audit readiness.
