Security Hot Spots for Organizing Security Knowledge

“The key to success in any field is identifying the hot spots and then creating a comprehensive, well thought-out plan.” — Bruce Bochy

The Security Hot Spots framework is a powerful tool that can help your organization better manage and advance software security.

As a business leader, you know that security is critical for your organization. However, it can be overwhelming to navigate the vast amount of information out there on security principles, patterns, and practices.

That’s where the Security Hot Spots framework comes in. I created the Security Hot Spots framework a lens for security that can help you find, organize, and share software security knowledge in a more actionable way.

I had worked on several large knowledge bases and knowledge management systems at Microsoft, so I wanted to apply that knowledge to advance the software security space.  I figured the best way to advance security would be to create a set of categories for knowledge, similar to how the Project Management Body of Knowledge created Knowledge Categories to advance project management.

And so the Security Hot Spots framework was born.

The Power of Security Hot Spots

By using Security Hot Spots, you can focus your attention on key categories, such as threats, attacks, vulnerabilities, and countermeasures, instead of dealing with a laundry list of information.

This can help simplify and clarify your approach to security, allowing you to gain insights and identify your best opportunities before wasting time down the wrong paths.

Think of Security Hot Spots as the Pareto Principle or 80/20 rule in action. By focusing on the 20% of security knowledge that has the highest ROI, you can effectively prioritize and optimize your security efforts.

Benefits of the Security Hot Spots

The Security Hot Spots framework provides several benefits for organizations looking to improve their security posture:

1. Chunking up the security space: The Security Hot Spots framework helps to divide the vast and complex security space into manageable chunks, making it easier to understand and approach.
2. Creating meaningful filters: Security Hot Spots create more meaningful filters for problem domains, allowing organizations to focus on specific areas of concern and tailor their security measures accordingly.
3. Providing durable, evolvable backdrops: The Security Hot Spots framework serves as a durable and evolvable backdrop for organizations to use as a reference point when rationalizing their security space. This helps to create a more cohesive and unified security strategy.
4. Living map: The framework is a living map that can be updated and expanded as new security issues arise or as the organization’s security needs change.
5. Dealing with information overload: Security Hot Spots can be used as a heat map to help organizations prioritize their security efforts and focus on the areas that require the most attention.
6. Guiding inspections: Security Hot Spots can be used to guide inspections of security designs, code, and deployments, ensuring that all aspects of security are being adequately addressed.
7. Reducing friction: By providing a clear and structured framework, Security Hot Spots can help to reduce friction between different stakeholders involved in the security process, promoting better communication and collaboration.

Security Hot Spots for Applications

With Security Hot Spots, it’s easy to walk the categories and think of potential security problems or mistakes.

The Security Hot Spots for Applications provides a way to chunk up the security space into manageable pieces to simplify the process of identifying and addressing security vulnerabilities.

The Application Level table includes several hot spots related to application security, such as input validation, output encoding, authentication, and authorization.

By focusing on these hot spots and ensuring they are properly addressed, developers can greatly improve the security of their applications.

Here are some example issues, grouped by Security Hot Spots Framework at the application level:

Hot Spots	Examples
Auditing and Logging	User denies performing an operation. Attacker exploits an application without trace. Attacker covers his tracks.
Authentication	Network eavesdropping. Brute force attacks. Dictionary attacks. Cookie replay attacks. Credential theft.
Authorization	Elevation of privilege. Disclosure of confidential data. Data tampering. Luring attacks.
Configuration Management	Unauthorized access to administration interfaces. Unauthorized access to configuration stores. Retrieval of clear text configuration secrets. Lack of individual accountability. Over-privileged process and service accounts.
Cryptography	Loss of decryption keys. Encryption cracking.
Exception Management	Revealing sensitive system or application details. Denial of service attacks.
Input and Data Validation	Buffer overflows. Cross-site scripting. SQL injection. Canonicalization attacks. Query string manipulation. Form field manipulation. Cookie manipulation. HTTP header manipulation.
Sensitive Data	Accessing sensitive data in storage. Accessing sensitive data in memory (including process dumps.) Network eavesdropping. Information disclosure.
Session Management	Session hijacking. Session replay. Man-in-the-middle attacks.

Security Hot Spots for Code

The Security Hot Spots for Code table lists various security hot spots for code-level security, including input validation, output encoding, authentication and access control, sensitive data handling, error handling, and logging and auditing.

Each hot spot includes a brief description, associated security concerns, and recommended practices to ensure secure coding.

The table serves as a helpful reference for developers to check their code for potential security vulnerabilities and ensure they are following best practices for secure coding.

Here’s a list of potential security mistakes and issues, grouped by Security Hot Spots at the code level:

Hot Spots	Examples
Authentication, Authorization and Trust	Comparing Classes by Name Single-Factor Authentication Hard-coded Passwords
Cryptography and Secrets	Key Exchange Without Entity Authentication Failure to Add Integrity Check Value Failure to Follow Chain of Trust in Certificate Validation
Language and Feature Misuse	Failure to Protect Class Data with Accessors
Logic Errors	Improper Pointer Subtraction Failure to Deallocate Memory Assigning Instead of Comparing
Memory	Null Pointer Dereference Using Freed Memory Doubly Freeing Memory
Range	Buffer Overflow Stack Overflow Heap Overflow
Synchronization and Timing	Race Condition in Time of Check, Time of Use Unsafe Function Call from Signal Handler Passing Mutable Objects to an Untrusted Method
Type	Format String Truncation Sign Conversion
Validation	Cross-site Scripting Command Injection Deserialization of Untrusted Data

Examples / Case Studies of the Security Hot Spots in Action

The Security Hot Spots Framework provides a way to organize security knowledge effectively and efficiently.

Examples of Security Hot Spots in action include security guides and books, competitive assessments, web application security frames, web services security frames, security engineering methodology, security inspections, security checklists, and threat modeling.

While the security guidance was downloaded several million times, the competitive assessments by 3rd parties were even more revealing.  In each case, the assessments revealed that the security guidance created using the Security Hot Spots was easier to use, more insightful, and more actionable.

By leveraging Security Hot Spots, organizations can focus on high ROI activities, drive results, and identify threats, attacks, and vulnerabilities.
