Secure operating systems
Secure coding
Capabilities and access control lists
computing
Hacker (computer security) or cracker, who accesses a computer system by circumventing its security system
Hacker (programmer subculture), who shares an anti-authoritarian approach to software development now associated with the free software movemen

The world is full of fascinating problems waiting to be solved.
No problem should ever have to be solved twice.
Boredom and drudgery are evil.
Freedom is good.
Attitude is no substitute for competence.

Help test and debug open-source software
Publish useful information
Help keep the infrastructure working

Reconnaissance
hackers first perform routine and detailed reconnaissance.
Methods of reconnaissance include Dumpster Diving, Social Engineering, Google Searching & Google Hacking, and work their way up to more insidious methods such as infiltrating your employees environments from coffee shops to simply walking in and setting up in a cubicle and asking a lot of questions.
Scanning
can reveal vulnerabilities that create a hit list, or triage
list, for hackers to work through.
Typically, hackers perform port scans and port mapping, while attempting to discover what services and versions of services are actively available on any open or available ports.
Gaining Access
Open ports can lead to a hacker gaining direct access to
services and possibly to internal network connections.
Whether the hacker is successful attacking an internal system has much to do with how vulnerable the specific system is, which is related to system configurations and architecture.
Maintain Access
Hackers may choose to continue attacking and exploiting
the target system, or to explore deeper into the target network and look for more systems and services
Hackers can continue to sniff your network looking for more information to use against you.
Covering Tracks
Most hackers will attempt to cover their footprints and tracks as carefully as possible.
Gaining root level access and administrative access is a big part of covering one’s tracks as the hacker can remove log entries and do so as a privileged administrator as opposed to an unknown hacker.

Alice sends a message to Bob, which is intercepted by Mallory:
Alice "Hi Bob, it's Alice. Give me your key"--> Mallory Bob
Mallory relays this message to Bob; Bob cannot tell it is not really from Alice:
Alice Mallory "Hi Bob, it's Alice. Give me your key"--> Bob
Bob responds with his encryption key:Alice Mallory <--[Bob's_key] Bob
Mallory replaces Bob's key with her own, and relays this to Alice, claiming that it is Bob's key:
Alice <--[Mallory's_key] Mallory Bob
Alice encrypts a message with what she believes to be Bob's key, thinking that only Bob can read it:
Alice "Meet me at the bus stop!"[encrypted with Mallory's key]--> Mallory Bob
