Information security due diligence is the process of assessing the current state of information security in an organization, identifying any gaps, risks, or vulnerabilities, and estimating the costs and efforts required to remediate them. Performing information security due diligence prior to making the purchase is important to determine the security exposures that may affect the value, reputation, or liability of the organization, as well as the feasibility and compatibility of integrating the security systems and processes of the two organizations.

Proactive monitoring (e.g., threat hunting, real-time log analysis, anomaly detection) is the most effective defense against Advanced Persistent Threats (APTs), which are stealthy, well-resourced, and long-term attacks.

APT actors:

Use zero-day exploits

Maintain long-term unauthorized access

Avoid detection

Traditional controls often fail. Proactive monitoring detects anomalies early, allowing for faster mitigation.

“Ongoing monitoring and detection programs are essential for identifying and responding to persistent and evolving threats.”

— CISM Review Manual 15th Edition, Chapter 4: Threat Management, Section: APT Detection Techniques*

The best step to address the situation of losing a smartphone that contains sensitive information is to remotely wipe the device, which means erasing all the data on the device and restoring it to factory settings. Remotely wiping the device can prevent unauthorized access to the sensitive information and protect the organization from data breaches or leaks. Remotely wiping the device can be done through services such as Find My Device for Android or Find My iPhone for iOS, or through mobile device management (MDM) solutions. The other options, such as disabling the user’s access, terminating the device connectivity, or escalating to the user’s management, may not be effective or timely enough to secure the sensitive information on the device.

The first thing that the information security manager should do after reading about a vendor product compromise on social media is to validate the risk to the organization. This means verifying the source and credibility of the information, determining if the organization uses the affected product, and assessing the potential impact and likelihood of the compromise on the organization’s data and systems. Validating the risk to the organization will help the information security manager to decide on the appropriate course of action, such as activating the incident response program, notifying relevant stakeholders, or performing a BIA.
