Study Notes
Cybersecurity Threat Environment
- The modern cybersecurity threat environment consists of various types of threats, each with distinct characteristics.
Threat Actors
- Cybersecurity threat actors differ in skills, capabilities, resources, and motivation.
- They can be internal or external to an organization.
- Internal threats can be just as dangerous as external threats.
- Threat actors can be categorized by their level of sophistication, ranging from unsophisticated script kiddies to advanced persistent threats (APTs).
- Resources and funding also vary among threat actors, with some having virtually limitless resources and others being hobbyists.
- Motivation and intent also differ, with some seeking thrills and others engaged in targeted corporate espionage.
Physical Security
- Physical security is crucial, as attackers who gain physical access to a component can compromise it.
- Attackers can exploit unsecured or poorly secured wireless networks, even from a parking lot.
- Removable media, such as USB drives, can be used to spread malware.
Supply Chain Risks
- Sophisticated attackers may target an organization's IT supply chain, gaining access to devices before they are delivered to the end user.
- This type of third-party risk is difficult to anticipate and address.
- Strong vendor management practices can help identify and mitigate these risks.
Threat Research
- Threat research involves gathering intelligence on modern cyber adversaries' tactics, techniques, and procedures (TTPs).
- Security companies and researchers engage in primary cybersecurity research to uncover TTPs.
- Security solution providers analyze customer data to identify TTPs.
- Honeynets are used to observe how hackers interact with vulnerable systems.
- The dark web is a primary source of threat intelligence.
Threat Intelligence
- Organizations need reliable, up-to-date threat intelligence feeds to stay ahead of threats.
- Multiple feeds can be used to validate information.
- Threat maps provide a geographic view of the threat landscape.
- However, geographic attribution is often unreliable due to attackers relaying attacks through cloud services and compromised networks.
Assessing Threat Intelligence
- Timeliness, accuracy, and relevance are key factors in assessing threat intelligence sources.
- Confidence scores can be used to filter and prioritize threat intelligence based on trustworthiness.
- Low confidence information should not be ignored, but should be treated with caution.
Building a Threat Research Toolkit
- Sources for building a threat research toolkit include:
- Vendor security information websites
- Vulnerability and threat feeds from vendors, government agencies, and private organizations
- Academic journals and technical publications
- Professional conferences and local industry group meetings
- Social media accounts of prominent security professionals
- Information on adversary TTPs.
