+# API Reference: Implementing Memory Protection with DEP and ASLR
+
+## Windows PowerShell Commands
+
+```powershell
+# Check system-wide mitigations
+Get-ProcessMitigation -System
+# Check specific process
+Get-ProcessMitigation -Name chrome.exe
+# Set system-wide DEP
+Set-ProcessMitigation -System -Enable DEP
+# Import XML policy
+Set-ProcessMitigation -PolicyFilePath policy.xml
+# Export current policy
+Get-ProcessMitigation -RegistryConfigFilePath export.xml
+```
+
+## Memory Protection Mechanisms
+
+| Mechanism | OS | Description |
+|-----------|-----|------------|
+| DEP/NX | Windows/Linux | Prevent code execution from data pages |
+| ASLR | Windows/Linux | Randomize memory layout |
+| CFG | Windows | Control Flow Guard |
+| SEHOP | Windows | SEH Overwrite Protection |
+| Stack Canary | Linux | Detect stack buffer overflow |
+| PIE | Linux | Position-Independent Executable |
+| RELRO | Linux | Read-Only Relocations |
+| FORTIFY_SOURCE | Linux | Buffer overflow checks |
+
+## Linux ASLR Check
+
+```bash
+# Check ASLR level (0=off, 1=conservative, 2=full)
+cat /proc/sys/kernel/randomize_va_space
+# Enable full ASLR
+echo 2 > /proc/sys/kernel/randomize_va_space
+```
+
+## ELF Binary Check (checksec)
+
+```bash
+checksec --file=/usr/bin/target
+# Or with readelf
+readelf -l binary | grep GNU_STACK
+readelf -d binary | grep BIND_NOW
+```
+
+## GCC Compilation Flags
+
+| Flag | Protection |
+|------|-----------|
+| `-fstack-protector-strong` | Stack canary |
+| `-D_FORTIFY_SOURCE=2` | Buffer overflow checks |
+| `-pie -fPIE` | Position-independent |
+| `-Wl,-z,relro,-z,now` | Full RELRO |
+| `-Wl,-z,noexecstack` | NX stack |
