The concept of military readiness nevertheless probably does not adequately resonate with the average American to put those risks in context.
This is a brief one-chapter introduction to a very large and important topic. This chapter Security deals with protecting systems from deliberate attacks, either internal or external, from individuals intentionally attempting to steal information, damage information, or otherwise deliberately wreak havoc in some manner.
Some of the most common types of violations include: Breach of Confidentiality - Theft of private or confidential information, such as credit-card numbers, trade secrets, patents, secret formulas, manufacturing procedures, medical information, financial information, etc. Breach of Integrity - Unauthorized modification of data, which may have serious indirect consequences.
For example a popular game or other program's source code could be modified to open up security holes on users systems before being released to the public. Breach of Availability - Unauthorized destruction of data, often just for the "fun" of causing havoc and for bragging rites.
Vandalism of web sites is a common form of this violation. Theft of Service - Unauthorized use of resources, such as theft of CPU cycles, installation of daemons running an unauthorized file server, or tapping into the target's telephone or networking services.
Denial of Service, DOS - Preventing legitimate users from using the system, often by overloading and overwhelming the system with an excess of requests for service. One common attack is masquerading, in which the attacker pretends to be a trusted third party.
A variation of this is the man-in-the-middle, in which the attacker masquerades as both ends of the conversation to two targets. A replay attack involves repeating a valid transmission.
Sometimes this can be the entire attack, such as repeating a request for a money transferor other times the content of the original message is replaced with malicious content.
There are four levels at which a system must be protected: Physical - The easiest way to steal data is to pocket the backup tapes.
Also, access to the root console will often give the user special privileges, such as rebooting the system as root from removable media.
Even general access to terminals in a computer room offers some opportunities for an attacker, although today's modern high-speed networking environment provides more and more opportunities for remote attacks.
Human - There is some concern that the humans who are allowed access to a system be trustworthy, and that they cannot be coerced into breaching security.
However more and more attacks today are made via social engineering, which basically means fooling trustworthy people into accidentally breaching security.
Phishing involves sending an innocent-looking e-mail or web site designed to fool people into revealing confidential information. Dumpster Diving involves searching the trash or other locations for passwords that are written down. Passwords that are too hard to remember, or which must be changed frequently are more likely to be written down somewhere close to the user's station.
Password Cracking involves divining users passwords, either by watching them type in their passwords, knowing something about them like their pet's names, or simply trying all words in common dictionaries.
Note also that it is proper etiquette to look away from the keyboard while someone else is entering their password.What Are The Least Common Features Of Physical Security.
