1. Establish a baseline understanding of your organization's digital footprint.
This means understanding what systems and data your organization has, where it is stored, and who has access to it. You should also have a good idea of how these systems are used and what data is accessed most frequently. This information can help you to identify any vulnerabilities in your system and focus your investigation accordingly.
2. Identify authorized and unauthorized users.
It is important to know who is authorized to access your organization's data and systems, as well as who is not authorized. This can help you to quickly identify any unauthorized activity or access attempts.
3. Track user activity, including login times, access privileges, and changes to files or systems
By tracking user activity, you can see what people are doing on your systems and whether they are accessing the correct data and using the correct applications. This can help you to identify any malicious or unauthorized behavior.
4. Review external data sources for information about your organization
External data sources such as social media platforms, news websites, and public records databases can contain valuable information about your organization that may not be publicly available elsewhere. By reviewing these sources, you can gain a better understanding of any potential threats to your cybersecurity.
5. Use social media monitoring to track conversations about your company online
Social media platforms can be a valuable source of information for osint investigations, especially for tracking conversations about your company online. You can use tools like Twitter search or SocialMention to monitor mentions of your company across social media platforms. This can help you to identify any potential threats or vulnerabilities that may not be publicly visible elsewhere.
6. Analyze email traffic for suspicious or malicious activity
Email traffic can be a valuable source of information for osint investigations, especially for identifying malicious or spam emails that may be sent to your organization's employees. You can use tools like SpamTitan or Mimecast to scan email traffic for suspicious or malicious activity. This can help you to protect your organization from spam or malware attacks that may be launched through email communications.
7. Run malware scans on all devices and systems
Malware scans can help you to identify any malware infections that may be present on devices or systems within your organization. By identifying and removing any malware infections early on, you can help to prevent them from causing damage or spreading further within your network.
8. Monitor website bandwidth and usage to identify attacks or unauthorized access attempts
Monitoring website bandwidth and usage can help you to identify any unusual activity that may be taking place on your website. This can include unauthorized access attempts, as well as data breaches or other attacks that may be taking place. By monitoring website activity, you can quickly identify any potential threats and take steps to mitigate them.
9. Restrict access to sensitive data according to the need-to-know principle
Sensitive data should only be accessible to those who need it for their job duties. By restricting access to this data, you can help to prevent it from falling into the wrong hands. This can also help to limit the damage that may be caused by a data breach or other security incident.
10. Educate employees about cybersecurity threats and best practices
Employees should be properly educated about cybersecurity threats and best practices. By teaching employees how to identify and avoid potential threats, you can help to reduce the risk of a security incident occurring within your organization. You can also provide employees with the knowledge and skills they need to properly respond to a security incident if one does occur.
