Network and Application Attacks

Application Attacks (Server Side)

Cross Site Scripting (XSS)

How to Defense Cross Site Scripting (XSS)

• Web masters should determine that their web pages validateinput, do not echo bad input to the user, and do not allowinput of code where it does not belong

• Web server administrators should make sure web services anddatabase programs are up to date on patches

• Users should never click an embedded link in an emailmessage without being sure where that link leads

Application Attacks (Server Side)

SQL Injection

How to Defense SQL INJECTION

• Validate input, rejecting SQL commands and scripts

• Provide drop down lists of choices for users (preparedstatements) instead of allowing free form entry

• Do not assign more privileges than the users need

• Do not ask users for SQL commands (yes, some systems haveallowed users to do this)

• Don't give your data tables and fields obvious names: aSELECT command must call a table and its columns by theircorrect names, or the command will fail
