Outside-In Hacker Attacks

No Password Disabling
– Hacker routines love systems that do not disable a user ID after repeated password attempts.  On these systems, they run bots to try hundreds of thousands of passwords until they gain entry.

Man-in-the Middle Attacks – Hackers can gain access to computer systems by guessing the IP address of a connected user and sending a TCP/IP packet with that user’s IP information.

Trojan Horse Access – Once a hacker gets a user’s IP address, they can map-out phony sign-on screens to their boss and get a privileged password.  These attacks are usually easy to use tools such as ASP and Active-X that allows HTML pages to be redirected to the user’s IP address.

Buffer Overflow Attacks – In these attacks, the web cache buffer is deliberately overloaded to gain unauthorized entry to the system.

Injection Threats – Many database systems have vulnerabilities in which access to confidential data can be gained via a SQL injection, a technique where a “1=1” string is added to a sign-on string.  For example, this query might return the real password for a user named Jane: 

select
   userid, password
from
   dba_users

OR 1=1;”
