DEXIT Security Technology
Dynamic Base Address
Dynamic Base Address in DEXIT leverages Address Space Layout Randomization (ASLR) to enhance security by randomizing memory addresses used by system and application processes. This makes it significantly harder for attackers to predict the location of specific functions or data structures.
Key Benefits:
- Increased Unpredictability: The architecture ensures that memory addresses are randomized, making it difficult for attackers to predict where to inject malicious code.
- Mitigation of Buffer Overflow Attacks: By randomizing the memory layout each time the program runs, DEXIT Sidekick helps prevent buffer overflow attacks.
- Reduced Exploit Reliability: Attackers cannot rely on fixed memory addresses, which decreases the success rate of exploits.
- Enhanced System Security: This feature adds an additional layer of security, complicating efforts to exploit vulnerabilities.
- Compatibility with Other Security Measures: The architecture works seamlessly with other security features like Data Execution Prevention (DEP) to provide comprehensive protection.
Data Execution Prevention (DEP)
Data Execution Prevention (DEP) in DEXIT Sidekick prevents code from being executed in certain regions of memory that are marked as non-executable. This is crucial for protecting against attacks that attempt to execute code from data pages, such as buffer overflow attacks.
Key Benefits:
- Prevention of Code Execution in Data Pages: DEP ensures that code cannot be executed from data-only memory regions, blocking many types of exploits.
- Protection Against Buffer Overflows: By preventing execution in non-executable memory, DEXIT Sidekick mitigates buffer overflow attacks.
- Enhanced System Integrity: DEP helps maintain system integrity by ensuring that only code from executable regions can run.
- Reduced Attack Surface: The architecture limits the areas of memory where code can be executed, reducing the potential attack surface for malicious actors.
- Integration with Modern CPUs: DEP leverages hardware-based support from modern CPUs to enforce execution restrictions, providing robust protection.
