+# Description:
+#
+# Modern Linux distributions offer some mitigation techniques to make it 
+# harder to exploit software vulnerabilities reliably. Mitigations such 
+# as RELRO, NoExecute (NX), Stack Canaries, Address Space Layout 
+# Randomization (ASLR) and Position Independent Executables (PIE) have 
+# made reliably exploiting any vulnerabilities that do exist far more 
+# challenging. The checksec.sh script is designed to test what *standard* 
+# Linux OS and PaX (http://pax.grsecurity.net/) security features are being 
+# used.
+#
+# As of version 1.3 the script also lists the status of various Linux kernel 
+# protection mechanisms.
+#
+# Credits:
+#
+# Thanks to Brad Spengler (grsecurity.net) for the PaX support.
+# Thanks to Jon Oberheide (jon.oberheide.org) for the kernel support.
+# Thanks to Ollie Whitehouse (Research In Motion) for rpath/runpath support.
