What is a Computer Safety?
Computer Safety is a branch to technologies heard as information safety as it is attached to computer. Information safety means protecting information and information systems from unauthorized access, use, opening, breaches, modification, or destruction. The Purpose to computer safety changes and can include protection to information from theft or corruptions, or conservations to accessibility, as defined in policy of safety.
Technological and administrative procedures enclosed to computer system to guarantee accessibility, wholeness and confidentiality to information controlled computer system
Computer safety obtrudes the requirements a computer, which differ from majority of the system
requirements since they often take the form of the restrictions on which computers are not expected that will do.
The Typical methods in perfecting computer safety can include following:
The Access Physically limit to computer on only that, which will not compromise safety.
The Hardware mechanisms, which obtrude the rules computer program, thereby avoiding depending on computer programs for computer safety.
The Mechanisms of the Operating system, which obtrude the rules a program to avoid to believe the computer program.
The Methodses of the programming to do the computer program dependable and resist to breach.
Computer Safety has three Layers:
o Forgery o Cracking o Phreaking
The Forgery:
Unauthorized use or attempts to avoid
or avoid the mechanisms to safety of the information system or network.
The Computer forgery always includes certain degree an encroachment in secrecy others or damage in machine characteristic such as, files, pages веб or software. The Influence of the computer forgery changes from simply simply invasive and сердясь on illegal.
The Cracking:
The Action of the breakup in computer system.
The Programme Cracking is a software modification to delete the methods of protection: prevention to copies, test/demonstration version, serial number, hardware key, cheque CD or programme annoyance like screen of the faultfinder and adware.
Most general programme rift is a modification of the applied binary code to cause or prevent the specific key branch in software execution.
Phreaking:
The Art and science of the cracking to telephone network.
Safety on purpose:
Technologies to computer safety are founded in logic. No universal standard notion which provides the behaviour. "Safety" is a notion, which unique in each situations. Safety external in functions of computer application, rather then auxiliary this, thereby to safety without fall obtrudes
the restrictions to applied behaviour.
There is several methods in safety on processing; sometimes combination of the methods in effect:
1. Believe whole software to keep the policy to safety but software not reliable (this - computer insecurity).
2. Believe whole software to keep the policy to safety and software is confirmed as reliable ( boring branch and analysis of the way for instance).
3. Do Not Believe the никакому to software but realize the policy to safety with mechanism, which not reliable (once again this - computer insecurity).
4. Do Not Believe the никакому to software but realize the policy to safety with reliable mechanism.
12 ends for computer safety:
1. Correction / patch ALL your software sometimes!
2. The Cheque / installation ALL your settings so they safe, with they ARENT by default!
3. Use firewall, like ZoneAlarm on control, which falls into and from your computer!
4. Use the good passwords: at least once 13marks long (the length), содержа both letter and numbers. Do Not forget to change your password each several months atleast and dont ever use same password on two places!
5. Get get prettier antivirus program: NOD32, F-Secure or Norton Antivirus
and keep is updated!
6. Open Don t or executes the files, which You - not 100% certainly - absolutely safe nomatter where or as You get them.
7. Vystirayte your historyfiles (like cookies, histories internet and temporary file, etc..), protocols and personal files, with specific deleting the program (like Wiping device) instead of exact deleting them.
8. The Cryptooperation of the Use to raise your secrecy! Use coded email (like Hushmail or Ziplip), www- concerning with serfing and code the sensitive files in your computer (PGP).
9. When You completed using some founded service internet like email, sign thereof rather then simply closing your browser! Also, when You leave your computer, make sure that nor one of such programs or relationship are left opened that anyone could abuse. In WindowsNT/2k/XP, the striking Windowskey+L to lock the workstation.
10. The Public computers of the use Don t for anything You it is necessary to bring their own input, beside them usually there is Troyanec horses, which seizes your passwords.
11. Do the copy and load them on safe place! The Easiest way to do general-copy - do "Image" your harddrive or separate and load this in safe position, but floppy-disks usually will simply be a spume for keeping document, etc..
12. Install and Use Hardware Firewall
